Official builds of DPDK +should always be done using ``make``, as described in the ``Getting Started +Guide`` documentation, and at "http://dpdk.org/doc/quick-start". + +Summary +-------- +For many platforms, compiling and installing DPDK should work using the +following set of commands:: + + meson build + cd build + ninja + ninja install + +This will compile DPDK in the ``build`` subdirectory, and then install the +resulting libraries, drivers and header files onto the system - generally +in /usr/local. A package-config file, ``libdpdk.pc``, for DPDK will also +be installed to allow ease of compiling and linking with applications. + +After installation, to use DPDK, the necessary CFLAG and LDFLAG variables +can be got from pkg-config:: + + pkg-config --cflags libdpdk + pkg-config --libs libdpdk + +More detail on each of these steps can be got from the following sections. + + +Getting the Tools +------------------ + +The ``meson`` tool is used to configure a DPDK build. On most Linux +distributions this can be got using the local package management system, +e.g. ``dnf install meson`` or ``apt-get install meson``. If meson is not +available as a suitable package, it can also be installed using the Python +3 ``pip`` tool, e.g. ``pip3 install meson``. Version 0.42 of meson is +recommended - if the version packaged is too old, the latest version is +generally available from "pip". + +The other dependency for building is the ``ninja`` tool, which acts similar +to make and performs the actual build using information provided by meson. +Installing meson will, in many cases, also install ninja, but, if not +already installed, it too is generally packaged by most Linux distributions. +If not available as a package, it can be downloaded as source or binary from +https://ninja-build.org/ + + +Configuring the Build +---------------------- + +To configure a build, run the meson tool, passing the path to the directory +to be used for the build e.g. ``meson build``, as shown above. If calling +meson from somewhere other than the root directory of the DPDK project the +path to the root directory should be passed as the first parameter, and the +build path as the second. For example, to build DPDK in /tmp/dpdk-build:: + + user@host:/tmp$ meson ~user/dpdk dpdk-build + +Meson will then configure the build based on settings in the project's +meson.build files, and by checking the build environment for e.g. compiler +properties or the presence of dependencies, such as libpcap, or openssl +libcrypto libraries. Once done, meson writes a ``build.ninja`` file in the +build directory to be used to do the build itself when ninja is called. + +Tuning of the build is possible, both as part of the original meson call, +or subsequently using ``meson configure`` command (``mesonconf`` in some +older versions). Some options, such as ``buildtype``, or ``werror`` are +built into meson, while others, such as ``max_lcores``, or the list of +examples to build, are DPDK-specific. To have a list of all options +available run ``meson configure`` in the build directory. + +Examples of adjusting the defaults when doing initial meson configuration. +Project-specific options are passed used -Doption=value:: + + meson --werror werrorbuild # build with warnings as errors + + meson --buildtype=debug debugbuild # build for debugging + + meson -Dexamples=l3fwd,l2fwd fwdbuild # build some examples as + # part of the normal DPDK build + + meson -Dmax_lcores=8 smallbuild # scale build for smaller systems + +Examples of setting the same options using meson configure:: + + meson configure -Dwerror=true + + meson configure -Dbuildtype=debug + + meson configure -Dexamples=l3fwd,l2fwd + + meson configure -Dmax_lcores=8 + +NOTE: once meson has been run to configure a build in a directory, it +cannot be run again on the same directory. Instead ``meson configure`` +should be used to change the build settings within the directory, and when +``ninja`` is called to do the build itself, it will trigger the necessary +re-scan from meson. + +As well as those settings taken from ``meson configure``, other options +such as the compiler to use can be passed via environment variables. For +example:: + + CC=clang meson clang-build + +NOTE: for more comprehensive overriding of compilers or other environment +settings, the tools for cross-compilation may be considered. However, for +basic overriding of the compiler etc., the above form works as expected. + + +Performing the Build +--------------------- + +Use ``ninja`` to perform the actual build inside the build folder +previously configured. In most cases no arguments are necessary. + +Ninja accepts a number of flags which are similar to make. For example, to +call ninja from outside the build folder, you can use ``ninja -C build``. +Ninja also runs parallel builds by default, but you can limit this using +the ``-j`` flag, e.g. ``ninja -j1 -v`` to do the build one step at a time, +printing each command on a new line as it runs. + + +Installing the Compiled Files +------------------------------ + +Use ``ninja install`` to install the required DPDK files onto the system. +The install prefix defaults to ``/usr/local`` but can be used as with other +options above. The environment variable ``DEST_DIR`` can be used to adjust +the root directory for the install, for example when packaging. + +With the base install directory, the individual directories for libraries +and headers are configurable. By default, the following will be the +installed layout:: + + headers -> /usr/local/include + libraries -> /usr/local/lib64 + drivers -> /usr/local/lib64/dpdk/drivers + libdpdk.pc -> /usr/local/lib64/pkgconfig + +For the drivers, these will also be symbolically linked into the library +install directory, so that ld.so can find them in cases where one driver may +depend on another, e.g. a NIC PMD depending upon the PCI bus driver. Within +the EAL, the default search path for drivers will be set to the configured +driver install path, so dynamically-linked applications can be run without +having to pass in ``-d /path/to/driver`` options for standard drivers. + + +Cross Compiling DPDK +-------------------- + +To cross-compile DPDK on a desired target machine we can use the following +command:: + + meson cross-build --cross-file <target_machine_configuration> + +For example if the target machine is arm64 we can use the following +command:: + meson arm-build --cross-file config/arm/arm64_armv8_linuxapp_gcc + +where config/arm/arm64_armv8_linuxapp_gcc contains the following +parameters:: + + [binaries] + c = 'aarch64-linux-gnu-gcc' + cpp = 'aarch64-linux-gnu-cpp' + ar = 'aarch64-linux-gnu-ar' + + [host_machine] + system = 'linux' + cpu_family = 'aarch64' + cpu = 'armv8-a' + endian = 'little' + + +Using the DPDK within an Application +------------------------------------- + +To compile and link against DPDK within an application, pkg-config should +be used to query the correct parameters.

\ + (y) += 2; \ + } while(0) + +.. note:: + + Wherever possible, enums and inline functions should be preferred to macros, since they provide additional degrees of type-safety and can allow compilers to emit extra warnings about unsafe code. + +Conditional Compilation +~~~~~~~~~~~~~~~~~~~~~~~ + +* When code is conditionally compiled using ``#ifdef`` or ``#if``, a comment may be added following the matching + ``#endif`` or ``#else`` to permit the reader to easily discern where conditionally compiled code regions end. +* This comment should be used only for (subjectively) long regions, regions greater than 20 lines, or where a series of nested ``#ifdef``'s may be confusing to the reader. + Exceptions may be made for cases where code is conditionally not compiled for the purposes of lint(1), or other tools, even though the uncompiled region may be small. +* The comment should be separated from the ``#endif`` or ``#else`` by a single space. +* For short conditionally compiled regions, a closing comment should not be used. +* The comment for ``#endif`` should match the expression used in the corresponding ``#if`` or ``#ifdef``. +* The comment for ``#else`` and ``#elif`` should match the inverse of the expression(s) used in the preceding ``#if`` and/or ``#elif`` statements. +* In the comments, the subexpression ``defined(FOO)`` is abbreviated as "FOO". + For the purposes of comments, ``#ifndef FOO`` is treated as ``#if !defined(FOO)``. + +.. code-block:: c + + #ifdef KTRACE + #include <sys/ktrace.h> + #endif + + #ifdef COMPAT_43 + /* A large region here, or other conditional code. */ + #else /* !COMPAT_43 */ + /* Or here. */ + #endif /* COMPAT_43 */ + + #ifndef COMPAT_43 + /* Yet another large region here, or other conditional code. */ + #else /* COMPAT_43 */ + /* Or here. */ + #endif /* !COMPAT_43 */ + +.. note:: + + Conditional compilation should be used only when absolutely necessary, as it increases the number of target binaries that need to be built and tested. + +C Types +------- + +Integers +~~~~~~~~ + +For fixed/minimum-size integer values, the project uses the form uintXX_t (from stdint.h) instead of older BSD-style integer identifiers of the form u_intXX_t. + +Enumerations +~~~~~~~~~~~~ + +* Enumeration values are all uppercase. + +.. code-block:: c + + enum enumtype { ONE, TWO } et; + +* Enum types should be used in preference to macros #defining a set of (sequential) values. +* Enum types should be prefixed with ``rte_`` and the elements by a suitable prefix [generally starting ``RTE_<enum>_`` - where <enum> is a shortname for the enum type] to avoid namespace collisions. + +Bitfields +~~~~~~~~~ + +The developer should group bitfields that are included in the same integer, as follows: + +.. code-block:: c + + struct grehdr { + uint16_t rec:3, + srr:1, + seq:1, + key:1, + routing:1, + csum:1, + version:3, + reserved:4, + ack:1; + /* ... */ + } + +Variable Declarations +~~~~~~~~~~~~~~~~~~~~~ + +In declarations, do not put any whitespace between asterisks and adjacent tokens, except for tokens that are identifiers related to types. +(These identifiers are the names of basic types, type qualifiers, and typedef-names other than the one being declared.) +Separate these identifiers from asterisks using a single space. + +For example: + +.. code-block:: c + + int *x; /* no space after asterisk */ + int * const x; /* space after asterisk when using a type qualifier */ + +* All externally-visible variables should have an ``rte_`` prefix in the name to avoid namespace collisions. +* Do not use uppercase letters - either in the form of ALL_UPPERCASE, or CamelCase - in variable names. + Lower-case letters and underscores only. + +Structure Declarations +~~~~~~~~~~~~~~~~~~~~~~ + +* In general, when declaring variables in new structures, declare them sorted by use, then by size (largest to smallest), and then in alphabetical order. + Sorting by use means that commonly used variables are used together and that the structure layout makes logical sense. + Ordering by size then ensures that as little padding is added to the structure as possible. +* For existing structures, additions to structures should be added to the end so for backward compatibility reasons. +* Each structure element gets its own line. +* Try to make the structure readable by aligning the member names using spaces as shown below. +* Names following extremely long types, which therefore cannot be easily aligned with the rest, should be separated by a single space. + +.. code-block:: c + + struct foo { + struct foo *next; /* List of active foo. */ + struct mumble amumble; /* Comment for mumble. */ + int bar; /* Try to align the comments. */ + struct verylongtypename *baz; /* Won't fit with other members */ + }; + + +* Major structures should be declared at the top of the file in which they are used, or in separate header files if they are used in multiple source files. +* Use of the structures should be by separate variable declarations and those declarations must be extern if they are declared in a header file. +* Externally visible structure definitions should have the structure name prefixed by ``rte_`` to avoid namespace collisions. + +Queues +~~~~~~ + +Use queue(3) macros rather than rolling your own lists, whenever possible. +Thus, the previous example would be better written: + +.. code-block:: c + + #include <sys/queue.h> + + struct foo { + LIST_ENTRY(foo) link; /* Use queue macros for foo lists. */ + struct mumble amumble; /* Comment for mumble. */ + int bar; /* Try to align the comments. */ + struct verylongtypename *baz; /* Won't fit with other members */ + }; + LIST_HEAD(, foo) foohead; /* Head of global foo list. */ + + +DPDK also provides an optimized way to store elements in lockless rings. +This should be used in all data-path code, when there are several consumer and/or producers to avoid locking for concurrent access. + +Typedefs +~~~~~~~~ + +Avoid using typedefs for structure types. + +For example, use: + +.. code-block:: c + + struct my_struct_type { + /* ... */ + }; + + struct my_struct_type my_var; + + +rather than: + +.. code-block:: c + + typedef struct my_struct_type { + /* ... */ + } my_struct_type; + + my_struct_type my_var + + +Typedefs are problematic because they do not properly hide their underlying type; +for example, you need to know if the typedef is the structure itself, as shown above, or a pointer to the structure. +In addition, they must be declared exactly once, whereas an incomplete structure type can be mentioned as many times as necessary. +Typedefs are difficult to use in stand-alone header files. +The header that defines the typedef must be included before the header that uses it, or by the header that uses it (which causes namespace pollution), +or there must be a back-door mechanism for obtaining the typedef. + +Note that #defines used instead of typedefs also are problematic (since they do not propagate the pointer type correctly due to direct text replacement). +For example, ``#define pint int *`` does not work as expected, while ``typedef int *pint`` does work. +As stated when discussing macros, typedefs should be preferred to macros in cases like this. + +When convention requires a typedef; make its name match the struct tag. +Avoid typedefs ending in ``_t``, except as specified in Standard C or by POSIX. + +.. note:: + + It is recommended to use typedefs to define function pointer types, for reasons of code readability. + This is especially true when the function type is used as a parameter to another function. + +For example: + +.. code-block:: c + + /** + * Definition of a remote launch function. + */ + typedef int (lcore_function_t)(void *); + + /* launch a function of lcore_function_t type */ + int rte_eal_remote_launch(lcore_function_t *f, void *arg, unsigned slave_id); + + +C Indentation +------------- + +General +~~~~~~~ + +* Indentation is a hard tab, that is, a tab character, not a sequence of spaces, + +.. note:: + + Global whitespace rule in DPDK, use tabs for indentation, spaces for alignment. + +* Do not put any spaces before a tab for indentation. +* If you have to wrap a long statement, put the operator at the end of the line, and indent again. +* For control statements (if, while, etc.), continuation it is recommended that the next line be indented by two tabs, rather than one, + to prevent confusion as to whether the second line of the control statement forms part of the statement body or not. + Alternatively, the line continuation may use additional spaces to line up to an appropriately point on the preceding line, for example, to align to an opening brace. + +.. note:: + + As with all style guidelines, code should match style already in use in an existing file. + +.. code-block:: c + + while (really_long_variable_name_1 == really_long_variable_name_2 && + var3 == var4){ /* confusing to read as */ + x = y + z; /* control stmt body lines up with second line of */ + a = b + c; /* control statement itself if single indent used */ + } + + if (really_long_variable_name_1 == really_long_variable_name_2 && + var3 == var4){ /* two tabs used */ + x = y + z;

See :ref:`doxygen_guidelines` for details. +* Functions that are part of the external API must have an ``rte_`` prefix on the function name. +* Do not use uppercase letters - either in the form of ALL_UPPERCASE, or CamelCase - in function names. Lower-case letters and underscores only. +* When prototyping functions, associate names with parameter types, for example: + +.. code-block:: c + + void function1(int fd); /* good */ + void function2(int); /* bad */ + +* Short function prototypes should be contained on a single line. + Longer prototypes, e.g. those with many parameters, can be split across multiple lines. + The second and subsequent lines should be further indented as for line statement continuations as described in the previous section. + +.. code-block:: c + + static char *function1(int _arg, const char *_arg2, + struct foo *_arg3, + struct bar *_arg4, + struct baz *_arg5); + static void usage(void); + +.. note:: + + Unlike function definitions, the function prototypes do not need to place the function return type on a separate line. + +Definitions +~~~~~~~~~~~ + +* The function type should be on a line by itself preceding the function. +* The opening brace of the function body should be on a line by itself. + +.. code-block:: c + + static char * + function(int a1, int a2, float fl, int a4) + { + + +* Do not declare functions inside other functions. + ANSI C states that such declarations have file scope regardless of the nesting of the declaration. + Hiding file declarations in what appears to be a local scope is undesirable and will elicit complaints from a good compiler. +* Old-style (K&R) function declaration should not be used, use ANSI function declarations instead as shown below. +* Long argument lists should be wrapped as described above in the function prototypes section. + +.. code-block:: c + + /* + * All major routines should have a comment briefly describing what + * they do. The comment before the "main" routine should describe + * what the program does. + */ + int + main(int argc, char *argv[]) + { + char *ep; + long num; + int ch; + +C Statement Style and Conventions +--------------------------------- + +NULL Pointers +~~~~~~~~~~~~~ + +* NULL is the preferred null pointer constant. + Use NULL instead of ``(type *)0`` or ``(type *)NULL``, except where the compiler does not know the destination type e.g. for variadic args to a function. +* Test pointers against NULL, for example, use: + +.. code-block:: c + + if (p == NULL) /* Good, compare pointer to NULL */ + + if (!p) /* Bad, using ! on pointer */ + + +* Do not use ! for tests unless it is a boolean, for example, use: + +.. code-block:: c + + if (*p == '\0') /* check character against (char)0 */ + +Return Value +~~~~~~~~~~~~ + +* Functions which create objects, or allocate memory, should return pointer types, and NULL on error. + The error type should be indicated may setting the variable ``rte_errno`` appropriately. +* Functions which work on bursts of packets, such as RX-like or TX-like functions, should return the number of packets handled. +* Other functions returning int should generally behave like system calls: + returning 0 on success and -1 on error, setting ``rte_errno`` to indicate the specific type of error. +* Where already standard in a given library, the alternative error approach may be used where the negative value is not -1 but is instead ``-errno`` if relevant, for example, ``-EINVAL``. + Note, however, to allow consistency across functions returning integer or pointer types, the previous approach is preferred for any new libraries. +* For functions where no error is possible, the function type should be ``void`` not ``int``. +* Routines returning ``void *`` should not have their return values cast to any pointer type. + (Typecasting can prevent the compiler from warning about missing prototypes as any implicit definition of a function returns int, + which, unlike ``void *``, needs a typecast to assign to a pointer variable.) + +.. note:: + + The above rule about not typecasting ``void *`` applies to malloc, as well as to DPDK functions. + +* Values in return statements should not be enclosed in parentheses. + +Logging and Errors +~~~~~~~~~~~~~~~~~~ + +In the DPDK environment, use the logging interface provided: + +.. code-block:: c + + /* register log types for this application */ + int my_logtype1 = rte_log_register("myapp.log1"); + int my_logtype2 = rte_log_register("myapp.log2"); + + /* set global log level to INFO */ + rte_log_set_global_level(RTE_LOG_INFO); + + /* only display messages higher than NOTICE for log2 (default + * is DEBUG) */ + rte_log_set_level(my_logtype2, RTE_LOG_NOTICE); + + /* enable all PMD logs (whose identifier string starts with "pmd") */ + rte_log_set_level_regexp("pmd.*", RTE_LOG_DEBUG); + + /* log in debug level */ + rte_log_set_global_level(RTE_LOG_DEBUG); + RTE_LOG(DEBUG, my_logtype1, "this is is a debug level message\n"); + RTE_LOG(INFO, my_logtype1, "this is is a info level message\n"); + RTE_LOG(WARNING, my_logtype1, "this is is a warning level message\n"); + RTE_LOG(WARNING, my_logtype2, "this is is a debug level message (not displayed)\n"); + + /* log in info level */ + rte_log_set_global_level(RTE_LOG_INFO); + RTE_LOG(DEBUG, my_logtype1, "debug level message (not displayed)\n"); + +Branch Prediction +~~~~~~~~~~~~~~~~~ + +* When a test is done in a critical zone (called often or in a data path) the code can use the ``likely()`` and ``unlikely()`` macros to indicate the expected, or preferred fast path. + They are expanded as a compiler builtin and allow the developer to indicate if the branch is likely to be taken or not. Example: + +.. code-block:: c + + #include <rte_branch_prediction.h> + if (likely(x > 1)) + do_stuff(); + +.. note:: + + The use of ``likely()`` and ``unlikely()`` should only be done in performance critical paths, + and only when there is a clearly preferred path, or a measured performance increase gained from doing so. + These macros should be avoided in non-performance-critical code. + +Static Variables and Functions +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +* All functions and variables that are local to a file must be declared as ``static`` because it can often help the compiler to do some optimizations (such as, inlining the code). +* Functions that should be inlined should to be declared as ``static inline`` and can be defined in a .c or a .h file. + +.. note:: + Static functions defined in a header file must be declared as ``static inline`` in order to prevent compiler warnings about the function being unused. + +Const Attribute +~~~~~~~~~~~~~~~ + +The ``const`` attribute should be used as often as possible when a variable is read-only. + +Inline ASM in C code +~~~~~~~~~~~~~~~~~~~~ + +The ``asm`` and ``volatile`` keywords do not have underscores. The AT&T syntax should be used. +Input and output operands should be named to avoid confusion, as shown in the following example: + +.. code-block:: c + + asm volatile("outb %[val], %[port]" + : : + [port] "dN" (port), + [val] "a" (val)); + +Control Statements +~~~~~~~~~~~~~~~~~~ + +* Forever loops are done with for statements, not while statements. +* Elements in a switch statement that cascade should have a FALLTHROUGH comment. For example: + +.. code-block:: c + + switch (ch) { /* Indent the switch. */ + case 'a': /* Don't indent the case. */ + aflag = 1; /* Indent case body one tab. */ + /* FALLTHROUGH */ + case 'b': + bflag = 1; + break; + case '?': + default: + usage(); + /* NOTREACHED */ + } + +Dynamic Logging +--------------- + +DPDK provides infrastructure to perform logging during runtime. This is very +useful for enabling debug output without recompilation. To enable or disable +logging of a particular topic, the ``--log-level`` parameter can be provided +to EAL, which will change the log level. DPDK code can register topics, +which allows the user to adjust the log verbosity for that specific topic. + +In general, the naming scheme is as follows: ``type.section.name`` + + * Type is the type of component, where ``lib``, ``pmd``, ``bus`` and ``user`` + are the common options. + * Section refers to a specific area, for example a poll-mode-driver for an + ethernet device would use ``pmd.net``, while an eventdev PMD uses + ``pmd.event``. + * The name identifies the individual item that the log applies to. + The name section must align with + the directory that the PMD code resides. See examples below for clarity. + +Examples: + + * The virtio network PMD in ``drivers/net/virtio`` uses ``pmd.net.virtio`` + * The eventdev software poll mode driver in ``drivers/event/sw`` uses ``pmd.event.sw`` + * The octeontx mempool driver in ``drivers/mempool/octeontx`` uses ``pmd.mempool.octeontx`` + * The DPDK hash library in ``lib/librte_hash`` uses ``lib.hash`` + +Specializations +~~~~~~~~~~~~~~~ + +In addition to the above logging topic, any PMD or library can further split +logging output by using "specializations". A specialization could be the +difference between initialization code, and logs of events that occur at runtime. + +An example could be the initialization log messages getting one +specialization, while another specialization handles mailbox command logging. +Each PMD, library or component can create as many specializations as required. + +A specialization looks like this: + + * Initialization output: ``type.section.name.init`` + * PF/VF mailbox output: ``type.section.name.mbox`` + +A real world example is the i40e poll mode driver which exposes two +specializations, one for initialization ``pmd.i40e.init`` and the other for +the remaining driver logs ``pmd.i40e.driver``. + +Note that specializations have no formatting rules, but please follow +a precedent if one exists. In order to see all current log topics and +specializations, run the ``app/test`` binary, and use the ``dump_log_types`` + +Python Code +----------- + +All Python code should work with Python 2.7+ and 3.2+ and be compliant with +`PEP8 (Style Guide for Python Code) <https://www.python.org/dev/peps/pep-0008/>`_. + +The ``pep8`` tool can be used for testing compliance with the guidelines. + +Integrating with the Build System +--------------------------------- + +DPDK supports being built in two different ways: + +* using ``make`` - or more specifically "GNU make", i.e. ``gmake`` on FreeBSD +* using the tools ``meson`` and ``ninja`` + +Any new library or driver to be integrated into DPDK should support being +built with both systems. While building using ``make`` is a legacy approach, and +most build-system enhancements are being done using ``meson`` and ``ninja`` +there are no plans at this time to deprecate the legacy ``make`` build system. + +Therefore all new component additions should include both a ``Makefile`` and a +``meson.build`` file, and should be added to the component lists in both the +``Makefile`` and ``meson.build`` files in the relevant top-level directory: +either ``lib`` directory or a ``driver`` subdirectory. + +Makefile Contents +~~~~~~~~~~~~~~~~~ + +The ``Makefile`` for the component should be of the following format, where +``<name>`` corresponds to the name of the library in question, e.g. hash, +lpm, etc. For drivers, the same format of Makefile is used. + +.. code-block:: none + + # pull in basic DPDK definitions, including whether library is to be + # built or not + include $(RTE_SDK)/mk/rte.vars.mk + + # library name + LIB = librte_<name>.a + + # any library cflags needed. Generally add "-O3 $(WERROR_FLAGS)" + CFLAGS += -O3 + CFLAGS += $(WERROR_FLAGS) + + # the symbol version information for the library, and .so version + EXPORT_MAP := rte_<name>_version.map + LIBABIVER := 1 + + # all source filenames are stored in SRCS-y + SRCS-$(CONFIG_RTE_LIBRTE_<NAME>) += rte_<name>.c + + # install includes + SYMLINK-$(CONFIG_RTE_LIBRTE_<NAME>)-include += rte_<name>.h + + # pull in rules to build the library + include $(RTE_SDK)/mk/rte.lib.mk + +Meson Build File Contents - Libraries +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The ``meson.build`` file for a new DPDK library should be of the following basic +format. + +.. code-block:: python + + sources = files('file1.c', ...) + headers = files('file1.c', ...) + + +The will build based on a number of conventions and assumptions within the DPDK +itself, for example, that the library name is the same as the directory name in +which the files are stored. + +For a library ``meson.build`` file, there are number of variables which can be +set, some mandatory, others optional. The mandatory fields are: + +sources + **Default Value = []**. + This variable should list out the files to be compiled up to create the + library. Files must be specified using the meson ``files()`` function. + + +The optional fields are: + +allow_experimental_apis + **Default Value = false** + Used to allow the library to make use of APIs marked as experimental. + Set to ``true`` if the C files in the library call any functions + marked as experimental in any included header files. + +build + **Default Value = true** + Used to optionally compile a library, based on its dependencies or + environment. A simple example of use would be: + +.. code-block:: python + + if host_machine.system() != 'linux' + build = false + endif + + +cflags + **Default Value = [<-march/-mcpu flags>]**. + Used to specify any additional cflags that need to be passed to compile + the sources in the library. + +deps + **Default Value = ['eal']**. + Used to list the internal library dependencies of the library. It should + be assigned to using ``+=`` rather than overwriting using ``=``. The + dependencies should be specified as strings, each one giving the name of + a DPDK library, without the ``librte_`` prefix. Dependencies are handled + recursively, so specifying e.g. ``mempool``, will automatically also + make the library depend upon the mempool library's dependencies too - + ``ring`` and ``eal``. For libraries that only depend upon EAL, this + variable may be omitted from the ``meson.build`` file. For example: + +.. code-block:: python + + deps += ['ethdev'] + + +ext_deps + **Default Value = []**. + Used to specify external dependencies of this library. They should be + returned as dependency objects, as returned from the meson + ``dependency()`` or ``find_library()`` functions. Before returning + these, they should be checked to ensure the dependencies have been + found, and, if not, the ``build`` variable should be set to ``false``. + For example: + +.. code-block:: python + + my_dep = dependency('libX', required: 'false') + if my_dep.found() + ext_deps += my_dep + else + build = false + endif + + +headers + **Default Value = []**. + Used to return the list of header files for the library that should be + installed to $PREFIX/include when ``ninja install`` is run. As with + source files, these should be specified using the meson ``files()`` + function. + +includes: + **Default Value = []**. + Used to indicate any additional header file paths which should be + added to the header search path for other libs depending on this + library. EAL uses this so that other libraries building against it + can find the headers in subdirectories of the main EAL directory. The + base directory of each library is always given in the include path, + it does not need to be specified here. + +name + **Default Value = library name derived from the directory name**. + If a library's .so or .a file differs from that given in the directory + name, the name should be specified using this variable. In practice, + since the convention is that for a library called ``librte_xyz.so``, the + sources are stored in a directory ``lib/librte_xyz``, this value should + never be needed for new libraries. + +.. note:: + + The name value also provides the name used to find the function version + map file, as part of the build process, so if the directory name and + library names differ, the ``version.map`` file should be named + consistently with the library, not the directory + +objs + **Default Value = []**. + This variable can be used to pass to the library build some pre-built + objects that were compiled up as part of another target given in the + included library ``meson.build`` file. + +version + **Default Value = 1**. + Specifies the ABI version of the library, and is used as the major + version number of the resulting ``.so`` library. + +Meson Build File Contents - Drivers +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +For drivers, the values are largely the same as for libraries. The variables +supported are: + +allow_experimental_apis + As above. + +build + As above. + +cflags + As above. + +deps + As above. + +ext_deps + As above. + +includes + **Default Value = <driver directory>** Some drivers include a base + directory for additional source files and headers, so we have this + variable to allow the headers from that base directory to be found when + compiling driver sources. Should be appended to using ``+=`` rather than + overwritten using ``=``. The values appended should be meson include + objects got using the ``include_directories()`` function. For example: + +.. code-block:: python + + includes += include_directories('base') + +name + As above, though note that each driver class can define it's own naming + scheme for the resulting ``.so`` files. + +objs + As above, generally used for the contents of the ``base`` directory. + +pkgconfig_extra_libs + **Default Value = []** + This variable is used to pass additional library link flags through to + the DPDK pkgconfig file generated, for example, to track any additional + libraries that may need to be linked into the build - especially when + using static libraries.

This includes guidelines for turning library statistics on and off and +requirements for preventing ABI changes when implementing statistics. + + +Mechanism to allow the application to turn library statistics on and off +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Each library that maintains statistics counters should provide a single build +time flag that decides whether the statistics counter collection is enabled or +not. This flag should be exposed as a variable within the DPDK configuration +file. When this flag is set, all the counters supported by current library are +collected for all the instances of every object type provided by the library. +When this flag is cleared, none of the counters supported by the current library +are collected for any instance of any object type provided by the library: + +.. code-block:: console + + # DPDK file config/common_linuxapp, config/common_bsdapp, etc. + CONFIG_RTE_<LIBRARY_NAME>_STATS_COLLECT=y/n + +The default value for this DPDK configuration file variable (either "yes" or +"no") is decided by each library. + + +Prevention of ABI changes due to library statistics support +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The layout of data structures and prototype of functions that are part of the +library API should not be affected by whether the collection of statistics +counters is turned on or off for the current library. In practical terms, this +means that space should always be allocated in the API data structures for +statistics counters and the statistics related API functions are always built +into the code, regardless of whether the statistics counter collection is turned +on or off for the current library. + +When the collection of statistics counters for the current library is turned +off, the counters retrieved through the statistics related API functions should +have a default value of zero. + + +Motivation to allow the application to turn library statistics on and off +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +It is highly recommended that each library provides statistics counters to allow +an application to monitor the library-level run-time events. Typical counters +are: number of packets received/dropped/transmitted, number of buffers +allocated/freed, number of occurrences for specific events, etc. + +However, the resources consumed for library-level statistics counter collection +have to be spent out of the application budget and the counters collected by +some libraries might not be relevant to the current application. In order to +avoid any unwanted waste of resources and/or performance impacts, the +application should decide at build time whether the collection of library-level +statistics counters should be turned on or off for each library individually. + +Library-level statistics counters can be relevant or not for specific +applications: + +* For Application A, counters maintained by Library X are always relevant and + the application needs to use them to implement certain features, such as traffic + accounting, logging, application-level statistics, etc. In this case, + the application requires that collection of statistics counters for Library X is + always turned on. + +* For Application B, counters maintained by Library X are only useful during the + application debug stage and are not relevant once debug phase is over. In this + case, the application may decide to turn on the collection of Library X + statistics counters during the debug phase and at a later stage turn them off. + +* For Application C, counters maintained by Library X are not relevant at all. + It might be that the application maintains its own set of statistics counters + that monitor a different set of run-time events (e.g. number of connection + requests, number of active users, etc). It might also be that the application + uses multiple libraries (Library X, Library Y, etc) and it is interested in the + statistics counters of Library Y, but not in those of Library X. In this case, + the application may decide to turn the collection of statistics counters off for + Library X and on for Library Y. + +The statistics collection consumes a certain amount of CPU resources (cycles, +cache bandwidth, memory bandwidth, etc) that depends on: + +* Number of libraries used by the current application that have statistics + counters collection turned on. + +* Number of statistics counters maintained by each library per object type + instance (e.g. per port, table, pipeline, thread, etc). + +* Number of instances created for each object type supported by each library. + +* Complexity of the statistics logic collection for each counter: when only + some occurrences of a specific event are valid, additional logic is typically + needed to decide whether the current occurrence of the event should be counted + or not. For example, in the event of packet reception, when only TCP packets + with destination port within a certain range should be recorded, conditional + branches are usually required. When processing a burst of packets that have been + validated for header integrity, counting the number of bits set in a bitmask + might be needed. + +PF and VF Considerations +------------------------ + +The primary goal of DPDK is to provide a userspace dataplane. Managing VFs from +a PF driver is a control plane feature and developers should generally rely on +the Linux Kernel for that. + +Developers should work with the Linux Kernel community to get the required +functionality upstream. PF functionality should only be added to DPDK for +testing and prototyping purposes while the kernel work is ongoing. It should +also be marked with an "EXPERIMENTAL" tag. If the functionality isn't +upstreamable then a case can be made to maintain the PF functionality in DPDK +without the EXPERIMENTAL tag. diff --git a/dpdk/doc/guides/contributing/documentation.rst

the developer. + +* **Release Notes** + + The Release Notes document which features have been added in the current and previous releases of DPDK and highlight + any known issues. + The Releases Notes also contain notifications of features that will change ABI compatibility in the next major release. + + Developers should include updates to the Release Notes with patch sets that relate to any of the following sections: + + * New Features + * Resolved Issues (see below) + * Known Issues + * API Changes + * ABI Changes + * Shared Library Versions + + Resolved Issues should only include issues from previous releases that have been resolved in the current release. + Issues that are introduced and then fixed within a release cycle do not have to be included here. + + Refer to the Release Notes from the previous DPDK release for the correct format of each section. + + +* **API documentation** + + The API documentation explains how to use the public DPDK functions. + The `API index page <http://dpdk.org/doc/api/>`_ shows the generated API documentation with related groups of functions. + + The API documentation should be updated via Doxygen comments when new functions are added. + +* **Getting Started Guides** + + The Getting Started Guides show how to install and configure DPDK and how to run DPDK based applications on different OSes. + + A Getting Started Guide should be added when DPDK is ported to a new OS. + +* **The Programmers Guide** + + The Programmers Guide explains how the API components of DPDK such as the EAL, Memzone, Rings and the Hash Library work. + It also explains how some higher level functionality such as Packet Distributor, Packet Framework and KNI work. + It also shows the build system and explains how to add applications. + + The Programmers Guide should be expanded when new functionality is added to DPDK. + +* **App Guides** + + The app guides document the DPDK applications in the ``app`` directory such as ``testpmd``. + + The app guides should be updated if functionality is changed or added. + +* **Sample App Guides** + + The sample app guides document the DPDK example applications in the examples directory. + Generally they demonstrate a major feature such as L2 or L3 Forwarding, Multi Process or Power Management. + They explain the purpose of the sample application, how to run it and step through some of the code to explain the + major functionality. + + A new sample application should be accompanied by a new sample app guide. + The guide for the Skeleton Forwarding app is a good starting reference. + +* **Network Interface Controller Drivers** + + The NIC Drivers document explains the features of the individual Poll Mode Drivers, such as software requirements, + configuration and initialization. + + New documentation should be added for new Poll Mode Drivers. + +* **Guidelines** + + The guideline documents record community process, expectations and design directions. + + They can be extended, amended or discussed by submitting a patch and getting community approval. + + +Building the Documentation +-------------------------- + +Dependencies +~~~~~~~~~~~~ + + +The following dependencies must be installed to build the documentation: + +* Doxygen. + +* Sphinx (also called python-sphinx). + +* TexLive (at least TexLive-core and the extra Latex support). + +* Inkscape. + +`Doxygen`_ generates documentation from commented source code. +It can be installed as follows: + +.. code-block:: console + + # Ubuntu/Debian. + sudo apt-get -y install doxygen + + # Red Hat/Fedora. + sudo dnf -y install doxygen + +`Sphinx`_ is a Python documentation tool for converting RST files to Html or to PDF (via LaTeX). +For full support with figure and table captioning the latest version of Sphinx can be installed as follows: + +.. code-block:: console + + # Ubuntu/Debian. + sudo apt-get -y install python-pip + sudo pip install --upgrade sphinx + sudo pip install --upgrade sphinx_rtd_theme + + # Red Hat/Fedora. + sudo dnf -y install python-pip + sudo pip install --upgrade sphinx + sudo pip install --upgrade sphinx_rtd_theme + +For further information on getting started with Sphinx see the `Sphinx Tutorial <http://sphinx-doc.org/tutorial.html>`_. + +.. Note:: + + To get full support for Figure and Table numbering it is best to install Sphinx 1.3.1 or later. + + +`Inkscape`_ is a vector based graphics program which is used to create SVG images and also to convert SVG images to PDF images. +It can be installed as follows: + +.. code-block:: console + + # Ubuntu/Debian. + sudo apt-get -y install inkscape + + # Red Hat/Fedora. + sudo dnf -y install inkscape + +`TexLive <http://www.tug.org/texlive/>`_ is an installation package for Tex/LaTeX. +It is used to generate the PDF versions of the documentation. +The main required packages can be installed as follows: + +.. code-block:: console + + # Ubuntu/Debian. + sudo apt-get -y install texlive-latex-extra + + # Red Hat/Fedora, selective install. + sudo dnf -y install texlive-collection-latexextra + + +Build commands +~~~~~~~~~~~~~~ + +The documentation is built using the standard DPDK build system. +Some examples are shown below: + +* Generate all the documentation targets:: + + make doc + +* Generate the Doxygen API documentation in Html:: + + make doc-api-html + +* Generate the guides documentation in Html:: + + make doc-guides-html + +* Generate the guides documentation in Pdf:: + + make doc-guides-pdf + +The output of these commands is generated in the ``build`` directory:: + + build/doc + |-- html + | |-- api + | +-- guides + | + +-- pdf + +-- guides + + +.. Note:: + + Make sure to fix any Sphinx or Doxygen warnings when adding or updating documentation. + +The documentation output files can be removed as follows:: + + make doc-clean + + +Document Guidelines +------------------- + +Here are some guidelines in relation to the style of the documentation: + +* Document the obvious as well as the obscure since it won't always be obvious to the reader. + For example an instruction like "Set up 64 2MB Hugepages" is better when followed by a sample commandline or a link to + the appropriate section of the documentation. + +* Use American English spellings throughout. + This can be checked using the ``aspell`` utility:: + + aspell --lang=en_US --check doc/guides/sample_app_ug/mydoc.rst + + +RST Guidelines +-------------- + +The RST (reStructuredText) format is a plain text markup format that can be converted to Html, PDF or other formats. +It is most closely associated with Python but it can be used to document any language. +It is used in DPDK to document everything apart from the API. + +The Sphinx documentation contains a very useful `RST Primer <http://sphinx-doc.org/rest.html#rst-primer>`_ which is a +good place to learn the minimal set of syntax required to format a document. + +The official `reStructuredText <http://docutils.sourceforge.net/rst.html>`_ website contains the specification for the +RST format and also examples of how to use it. +However, for most developers the RST Primer is a better resource. + +The most common guidelines for writing RST text are detailed in the +`Documenting Python <https://docs.python.org/devguide/documenting.html>`_ guidelines. +The additional guidelines below reiterate or expand upon those guidelines. + + +Line Length +~~~~~~~~~~~ + +* Lines in sentences should be less than 80 characters and wrapped at + words. Multiple sentences which are not separated by a blank line are joined + automatically into paragraphs. + +* Lines in literal blocks **must** be less than 80 characters since + they are not wrapped by the document formatters and can exceed the page width + in PDF documents. + + Long literal command lines can be shown wrapped with backslashes. For + example:: + + testpmd -l 2-3 -n 4 \ + --vdev=virtio_user0,path=/dev/vhost-net,queues=2,queue_size=1024 \ + -- -i --txqflags=0x0 --enable-hw-vlan --enable-lro \ + --enable-rx-cksum --txq=2 --rxq=2 --rxd=1024 --txd=1024 + + +Whitespace +~~~~~~~~~~ + +* Standard RST indentation is 3 spaces. + Code can be indented 4 spaces, especially if it is copied from source files. + +* No tabs. + Convert tabs in embedded code to 4 or 8 spaces. + +* No trailing whitespace. + +* Add 2 blank lines before each section header. + +* Add 1 blank line after each section header. + +* Add 1 blank line between each line of a list. + + +Section Headers +~~~~~~~~~~~~~~~ + +* Section headers should use the following underline formats:: + + Level 1 Heading + =============== + + + Level 2 Heading + --------------- + + + Level 3 Heading + ~~~~~~~~~~~~~~~ + + + Level 4 Heading + ^^^^^^^^^^^^^^^ + + +* Level 4 headings should be used sparingly. + +* The underlines should match the length of the text. + +* In general, the heading should be less than 80 characters, for conciseness. + +* As noted above: + + * Add 2 blank lines before each section header. + + * Add 1 blank line after each section header. + + +Lists +~~~~~ + +* Bullet lists should be formatted with a leading ``*`` as follows:: + + * Item one. + + * Item two is a long line that is wrapped and then indented to match + the start of the previous line. + + * One space character between the bullet and the text is preferred. + +* Numbered lists can be formatted with a leading number but the preference is to use ``#.`` which will give automatic numbering. + This is more convenient when adding or removing items:: + + #. Item one. + + #. Item two is a long line that is wrapped and then indented to match + the start of the previous line. + + #. Item three. + +* Definition lists can be written with or without a bullet:: + + * Item one. + + Some text about item one. + + * Item two. + + Some text about item two. + +* All lists, and sub-lists, must be separated from the preceding text by a blank line. + This is a syntax requirement. + +* All list items should be separated by a blank line for readability. + + +Code and Literal block sections +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +* Inline text that is required to be rendered with a fixed width font should be enclosed in backquotes like this: + \`\`text\`\`, so that it appears like this: ``text``. + +* Fixed width, literal blocks of texts should be indented at least 3 spaces and prefixed with ``::`` like this:: + + Here is some fixed width text:: + + 0x0001 0x0001 0x00FF 0x00FF + +* It is also possible to specify an encoding for a literal block using the ``.. code-block::`` directive so that syntax + highlighting can be applied. + Examples of supported highlighting are:: + + .. code-block:: console + .. code-block:: c + .. code-block:: python + .. code-block:: diff + .. code-block:: none + + That can be applied as follows:: + + .. code-block:: c + + #include<stdio.h> + + int main() { + + printf("Hello World\n"); + + return 0; + } + + Which would be rendered as: + + .. code-block:: c + + #include<stdio.h> + + int main() { + + printf("Hello World\n"); + + return 0; + } + + +* The default encoding for a literal block using the simplified ``::`` + directive is ``none``. + +* Lines in literal blocks must be less than 80 characters since they can exceed the page width when converted to PDF documentation. + For long literal lines that exceed that limit try to wrap the text at sensible locations. + For example a long command line could be documented like this and still work if copied directly from the docs:: + + build/app/testpmd -l 0-2 -n3 --vdev=net_pcap0,iface=eth0 \ + --vdev=net_pcap1,iface=eth1 \ + -- -i --nb-cores=2 --nb-ports=2 \ + --total-num-mbufs=2048 + +* Long lines that cannot be wrapped, such as application output, should be truncated to be less than 80 characters. + + +Images +~~~~~~ + +* All images should be in SVG scalar graphics format. + They should be true SVG XML files and should not include binary formats embedded in a SVG wrapper. + +* The DPDK documentation contains some legacy images in PNG format. + These will be converted to SVG in time. + +* `Inkscape <http://inkscape.org>`_ is the recommended graphics editor for creating the images. + Use some of the older images in ``doc/guides/prog_guide/img/`` as a template, for example ``mbuf1.svg`` + or ``ring-enqueue1.svg``. + +* The SVG images should include a copyright notice, as an XML comment. + +* Images in the documentation should be formatted as follows: + + * The image should be preceded by a label in the format ``.. _figure_XXXX:`` with a leading underscore and + where ``XXXX`` is a unique descriptive name. + + * Images should be included using the ``.. figure::`` directive and the file type should be set to ``*`` (not ``.svg``). + This allows the format of the image to be changed if required, without updating the documentation. + + * Images must have a caption as part of the ``.. figure::`` directive. + +* Here is an example of the previous three guidelines:: + + .. _figure_mempool: + + .. figure:: img/mempool.* + + A mempool in memory with its associated ring. + +.. _mock_label: + +* Images can then be linked to using the ``:numref:`` directive:: + + The mempool layout is shown in :numref:`figure_mempool`. + + This would be rendered as: *The mempool layout is shown in* :ref:`Fig 6.3 <mock_label>`. + + **Note**: The ``:numref:`` directive requires Sphinx 1.3.1 or later. + With earlier versions it will still be rendered as a link but won't have an automatically generated number. + +* The caption of the image can be generated, with a link, using the ``:ref:`` directive:: + + :ref:`figure_mempool` + + This would be rendered as: *A mempool in memory with its associated ring.* + +Tables +~~~~~~ + +* RST tables should be used sparingly. + They are hard to format and to edit, they are often rendered incorrectly in PDF format, and the same information + can usually be shown just as clearly with a definition or bullet list. + +* Tables in the documentation should be formatted as follows: + + * The table should be preceded by a label in the format ``.. _table_XXXX:`` with a leading underscore and where + ``XXXX`` is a unique descriptive name. + + * Tables should be included using the ``.. table::`` directive and must have a caption. + +* Here is an example of the previous two guidelines:: + + .. _table_qos_pipes: + + .. table:: Sample configuration for QOS pipes. + + +----------+----------+----------+ + | Header 1 | Header 2 | Header 3 | + | | | | + +==========+==========+==========+ + | Text | Text | Text | + +----------+----------+----------+ + | ... | ... | ... | + +----------+----------+----------+ + +* Tables can be linked to using the ``:numref:`` and ``:ref:`` directives, as shown in the previous section for images. + For example:: + + The QOS configuration is shown in :numref:`table_qos_pipes`. + +* Tables should not include merged cells since they are not supported by the PDF renderer. + + +.. _links: + +Hyperlinks +~~~~~~~~~~ + +* Links to external websites can be plain URLs. + The following is rendered as http://dpdk.org:: + + http://dpdk.org + +* They can contain alternative text. + The following is rendered as `Check out DPDK <http://dpdk.org>`_:: + + `Check out DPDK <http://dpdk.org>`_ + +* An internal link can be generated by placing labels in the document with the format ``.. _label_name``. + +* The following links to the top of this section: :ref:`links`:: + + .. _links: + + Hyperlinks + ~~~~~~~~~~ + + * The following links to the top of this section: :ref:`links`: + +.. Note:: + + The label must have a leading underscore but the reference to it must omit it. + This is a frequent cause of errors and warnings. + +* The use of a label is preferred since it works across files and will still work if the header text changes. + + +.. _doxygen_guidelines: + +Doxygen Guidelines +------------------ + +The DPDK API is documented using Doxygen comment annotations in the header files. +Doxygen is a very powerful tool, it is extremely configurable and with a little effort can be used to create expressive documents. +See the `Doxygen website <http://www.stack.nl/~dimitri/doxygen/>`_ for full details on how to use it. + +The following are some guidelines for use of Doxygen in the DPDK API documentation: + +* New libraries that are documented with Doxygen should be added to the Doxygen configuration file: ``doc/api/doxy-api.conf``. + It is only required to add the directory that contains the files. + It isn't necessary to explicitly name each file since the configuration matches all ``rte_*.h`` files in the directory. + +* Use proper capitalization and punctuation in the Doxygen comments since they will become sentences in the documentation. + This in particular applies to single line comments, which is the case the is most often forgotten. + +* Use ``@`` style Doxygen commands instead of ``\`` style commands. + +* Add a general description of each library at the head of the main header files: + + .. code-block:: c + + /** + * @file + * RTE Mempool. + * + * A memory pool is an allocator of fixed-size object. It is + * identified by its name, and uses a ring to store free objects. + * ... + */ + +* Document the purpose of a function, the parameters used and the return + value: + + .. code-block:: c + + /** + * Attach a new Ethernet device specified by arguments. + * + * @param devargs + * A pointer to a strings array describing the new device + * to be attached. The strings should be a pci address like + * `0000:01:00.0` or **virtual** device name like `net_pcap0`. + * @param port_id + * A pointer to a port identifier actually attached. + * + * @return + * 0 on success and port_id is filled, negative on error. + */ + int rte_eth_dev_attach(const char *devargs, uint8_t *port_id); + +* Doxygen supports Markdown style syntax such as bold, italics, fixed width text and lists. + For example the second line in the ``devargs`` parameter in the previous example will be rendered as: + + The strings should be a pci address like ``0000:01:00.0`` or **virtual** device name like ``net_pcap0``. + +* Use ``-`` instead of ``*`` for lists within the Doxygen comment since the latter can get confused with the comment delimiter. + +* Add an empty line between the function description, the ``@params`` and ``@return`` for readability. + +* Place the ``@params`` description on separate line and indent it by 2 spaces. + (It would be better to use no indentation since this is more common and also because checkpatch complains about leading + whitespace in comments. + However this is the convention used in the existing DPDK code.) + +* Documented functions can be linked to simply by adding ``()`` to the function name: + + .. code-block:: c + + /** + * The functions exported by the application Ethernet API to setup + * a device designated by its port identifier must be invoked in + * the following order: + * - rte_eth_dev_configure() + * - rte_eth_tx_queue_setup() + * - rte_eth_rx_queue_setup() + * - rte_eth_dev_start() + */ + + In the API documentation the functions will be rendered as links, see the + `online section of the rte_ethdev.h docs <http://dpdk.org/doc/api/rte__ethdev_8h.html>`_ that contains the above text. + +* The ``@see`` keyword can be used to create a *see also* link to another file or library. + This directive should be placed on one line at the bottom of the documentation section. + + .. code-block:: c + + /** + * ... + * + * Some text that references mempools. + * + * @see eal_memzone.c + */ + +* Doxygen supports two types of comments for documenting variables, constants and members: prefix and postfix: + + .. code-block:: c + + /** This is a prefix comment. */ + #define RTE_FOO_ERROR 0x023. + + #define RTE_BAR_ERROR 0x024. /**< This is a postfix comment. */ + +* Postfix comments are preferred for struct members and constants if they can be documented in the same way: + + .. code-block:: c + + struct rte_eth_stats { + uint64_t ipackets; /**< Total number of received packets. */ + uint64_t opackets; /**< Total number of transmitted packets.*/ + uint64_t ibytes; /**< Total number of received bytes. */ + uint64_t obytes; /**< Total number of transmitted bytes. */ + uint64_t imissed; /**< Total of RX missed packets. */ + uint64_t ibadcrc; /**< Total of RX packets with CRC error. */ + uint64_t ibadlen; /**< Total of RX packets with bad length. */ + } + + Note: postfix comments should be aligned with spaces not tabs in accordance + with the :ref:`coding_style`. + +* If a single comment type can't be used, due to line length limitations then + prefix comments should be preferred. + For example this section of the code contains prefix comments, postfix comments on the same line and postfix + comments on a separate line: + + .. code-block:: c + + /** Number of elements in the elt_pa array. */ + uint32_t pg_num __rte_cache_aligned; + uint32_t pg_shift; /**< LOG2 of the physical pages. */ + uintptr_t pg_mask; /**< Physical page mask value. */ + uintptr_t elt_va_start; + /**< Virtual address of the first mempool object. */ + uintptr_t elt_va_end; + /**< Virtual address of the <size + 1> mempool object. */ + phys_addr_t elt_pa[MEMPOOL_PG_NUM_DEFAULT]; + /**< Array of physical page addresses for the mempool buffer. */ + + This doesn't have an effect on the rendered documentation but it is confusing for the developer reading the code. + It this case it would be clearer to use prefix comments throughout: + + .. code-block:: c + + /** Number of elements in the elt_pa array. */ + uint32_t pg_num __rte_cache_aligned; + /** LOG2 of the physical pages. */ + uint32_t pg_shift; + /** Physical page mask value. */ + uintptr_t pg_mask; + /** Virtual address of the first mempool object. */ + uintptr_t elt_va_start; + /** Virtual address of the <size + 1> mempool object. */ + uintptr_t elt_va_end; + /** Array of physical page addresses for the mempool buffer. */ + phys_addr_t elt_pa[MEMPOOL_PG_NUM_DEFAULT]; + +* Check for Doxygen warnings in new code by checking the API documentation build:: + + make doc-api-html >/dev/null + +* Read the rendered section of the documentation that you have added for correctness, clarity and consistency + with the surrounding text. diff --git a/dpdk/doc/guides/contributing/img/patch_cheatsheet.svg b/dpdk/doc/guides/contributing/img/patch_cheatsheet.svg new file mode 100644 index 0000000..8522592 --- /dev/null

outlines the guidelines for submitting code to DPDK. + +The DPDK development process is modelled (loosely) on the Linux Kernel development model so it is worth reading the +Linux kernel guide on submitting patches: +`How to Get Your Change Into the Linux Kernel <https://www.kernel.org/doc/html/latest/process/submitting-patches.html>`_. +The rationale for many of the DPDK guidelines is explained in greater detail in the kernel guidelines. + + +The DPDK Development Process +---------------------------- + +The DPDK development process has the following features: + +* The code is hosted in a public git repository. +* There is a mailing list where developers submit patches. +* There are maintainers for hierarchical components. +* Patches are reviewed publicly on the mailing list. +* Successfully reviewed patches are merged to the repository. +* Patches should be sent to the target repository or sub-tree, see below. +* All sub-repositories are merged into main repository for ``-rc1`` and ``-rc2`` versions of the release. +* After the ``-rc2`` release all patches should target the main repository. + +The mailing list for DPDK development is `dev@dpdk.org <http://dpdk.org/ml/archives/dev/>`_. +Contributors will need to `register for the mailing list <http://dpdk.org/ml/listinfo/dev>`_ in order to submit patches. +It is also worth registering for the DPDK `Patchwork <http://dpdk.org/dev/patchwork/project/dpdk/list/>`_ + +The development process requires some familiarity with the ``git`` version control system. +Refer to the `Pro Git Book <http://www.git-scm.com/book/>`_ for further information. + +Source License +-------------- + +The DPDK uses the Open Source BSD-3-Clause license for the core libraries and +drivers. The kernel components are GPL-2.0 licensed. DPDK uses single line +reference to Unique License Identifiers in source files as defined by the Linux +Foundation's `SPDX project <http://spdx.org/>`_. + +DPDK uses first line of the file to be SPDX tag. In case of *#!* scripts, SPDX +tag can be placed in 2nd line of the file. + +For example, to label a file as subject to the BSD-3-Clause license, +the following text would be used: + +``SPDX-License-Identifier: BSD-3-Clause`` + +To label a file as dual-licensed with BSD-3-Clause and GPL-2.0 (e.g., for code +that is shared between the kernel and userspace), the following text would be +used: + +``SPDX-License-Identifier: (BSD-3-Clause OR GPL-2.0)`` + +Refer to ``licenses/README`` for more details. + +Maintainers and Sub-trees +------------------------- + +The DPDK maintenance hierarchy is divided into a main repository ``dpdk`` and sub-repositories ``dpdk-next-*``. + +There are maintainers for the trees and for components within the tree. + +Trees and maintainers are listed in the ``MAINTAINERS`` file. For example:: + + Crypto Drivers + -------------- + M: Some Name <some.name@email.com> + B: Another Name <another.name@email.com> + T: git://dpdk.org/next/dpdk-next-crypto + + Intel AES-NI GCM PMD + M: Some One <some.one@email.com> + F: drivers/crypto/aesni_gcm/ + F: doc/guides/cryptodevs/aesni_gcm.rst + +Where: + +* ``M`` is a tree or component maintainer. +* ``B`` is a tree backup maintainer. +* ``T`` is a repository tree. +* ``F`` is a maintained file or directory. + +Additional details are given in the ``MAINTAINERS`` file. + +The role of the component maintainers is to: + +* Review patches for the component or delegate the review. + The review should be done, ideally, within 1 week of submission to the mailing list. +* Add an ``acked-by`` to patches, or patchsets, that are ready for committing to a tree. +* Reply to questions asked about the component. + +Component maintainers can be added or removed by submitting a patch to the ``MAINTAINERS`` file. +Maintainers should have demonstrated a reasonable level of contributions or reviews to the component area. +The maintainer should be confirmed by an ``ack`` from an established contributor. +There can be more than one component maintainer if desired. + +The role of the tree maintainers is to: + +* Maintain the overall quality of their tree. + This can entail additional review, compilation checks or other tests deemed necessary by the maintainer. +* Commit patches that have been reviewed by component maintainers and/or other contributors. + The tree maintainer should determine if patches have been reviewed sufficiently. +* Ensure that patches are reviewed in a timely manner. +* Prepare the tree for integration. +* Ensure that there is a designated back-up maintainer and coordinate a handover for periods where the + tree maintainer can't perform their role. + +Tree maintainers can be added or removed by submitting a patch to the ``MAINTAINERS`` file. +The proposer should justify the need for a new sub-tree and should have demonstrated a sufficient level of contributions in the area or to a similar area. +The maintainer should be confirmed by an ``ack`` from an existing tree maintainer. +Disagreements on trees or maintainers can be brought to the Technical Board. + +The backup maintainer for the master tree should be selected from the existing sub-tree maintainers from the project. +The backup maintainer for a sub-tree should be selected from among the component maintainers within that sub-tree. + + +Getting the Source Code +----------------------- + +The source code can be cloned using either of the following: + +main repository:: + + git clone git://dpdk.org/dpdk + git clone http://dpdk.org/git/dpdk + +sub-repositories (`list <http://dpdk.org/browse/next>`_):: + + git clone git://dpdk.org/next/dpdk-next-* + git clone http://dpdk.org/git/next/dpdk-next-* + +Make your Changes +----------------- + +Make your planned changes in the cloned ``dpdk`` repo. Here are some guidelines and requirements: + +* Follow the :ref:`coding_style` guidelines. + +* If you add new files or directories you should add your name to the ``MAINTAINERS`` file. + +* New external functions should be added to the local ``version.map`` file. + See the :doc:`Guidelines for ABI policy and versioning </contributing/versioning>`. + New external functions should also be added in alphabetical order. + +* Important changes will require an addition to the release notes in ``doc/guides/rel_notes/``. + See the :ref:`Release Notes section of the Documentation Guidelines <doc_guidelines>` for details. + +* Test the compilation works with different targets, compilers and options, see :ref:`contrib_check_compilation`. + +* Don't break compilation between commits with forward dependencies in a patchset. + Each commit should compile on its own to allow for ``git bisect`` and continuous integration testing. + +* Add tests to the ``app/test`` unit test framework where possible. + +* Add documentation, if relevant, in the form of Doxygen comments or a User Guide in RST format. + See the :ref:`Documentation Guidelines <doc_guidelines>`. + +Once the changes have been made you should commit them to your local repo. + +For small changes, that do not require specific explanations, it is better to keep things together in the +same patch. +Larger changes that require different explanations should be separated into logical patches in a patchset. +A good way of thinking about whether a patch should be split is to consider whether the change could be +applied without dependencies as a backport. + +As a guide to how patches should be structured run ``git log`` on similar files. + + +Commit Messages: Subject Line +----------------------------- + +The first, summary, line of the git commit message becomes the subject line of the patch email. +Here are some guidelines for the summary line: + +* The summary line must capture the area and the impact of the change. + +* The summary line should be around 50 characters. + +* The summary line should be lowercase apart from acronyms. + +* It should be prefixed with the component name (use git log to check existing components). + For example:: + + ixgbe: fix offload config option name + + config: increase max queues per port + +* Use the imperative of the verb (like instructions to the code base). + +* Don't add a period/full stop to the subject line or you will end up two in the patch name: ``dpdk_description..patch``. + +The actual email subject line should be prefixed by ``[PATCH]`` and the version, if greater than v1, +for example: ``PATCH v2``. +The is generally added by ``git send-email`` or ``git format-patch``, see below. + +If you are submitting an RFC draft of a feature you can use ``[RFC]`` instead of ``[PATCH]``. +An RFC patch doesn't have to be complete. +It is intended as a way of getting early feedback. + + +Commit Messages: Body +--------------------- + +Here are some guidelines for the body of a commit message: + +* The body of the message should describe the issue being fixed or the feature being added. + It is important to provide enough information to allow a reviewer to understand the purpose of the patch. + +* When the change is obvious the body can be blank, apart from the signoff. + +* The commit message must end with a ``Signed-off-by:`` line which is added using:: + + git commit --signoff # or -s + + The purpose of the signoff is explained in the + `Developer's Certificate of Origin <https://www.kernel.org/doc/html/latest/process/submitting-patches.html#developer-s-certificate-of-origin-1-1>`_ + section of the Linux kernel guidelines. + + .. Note:: + + All developers must ensure that they have read and understood the + Developer's Certificate of Origin section of the documentation prior + to applying the signoff and submitting a patch. + +* The signoff must be a real name and not an alias or nickname. + More than one signoff is allowed. + +* The text of the commit message should be wrapped at 72 characters. + +* When fixing a regression, it is required to reference the id of the commit + which introduced the bug, and put the original author of that commit on CC. + You can generate the required lines using the following git alias, which prints + the commit SHA and the author of the original code:: + + git config alias.fixline "log -1 --abbrev=12 --format='Fixes: %h (\"%s\")%nCc: %ae'" + + The output of ``git fixline <SHA>`` must then be added to the commit message:: + + doc: fix some parameter description + + Update the docs, fixing description of some parameter. + + Fixes: abcdefgh1234 ("doc: add some parameter") + Cc: author@example.com + + Signed-off-by: Alex Smith <alex.smith@example.com> + +* When fixing an error or warning it is useful to add the error message and instructions on how to reproduce it. + +* Use correct capitalization, punctuation and spelling. + +In addition to the ``Signed-off-by:`` name the commit messages can also have +tags for who reported, suggested, tested and reviewed the patch being +posted. Please refer to the `Tested, Acked and Reviewed by`_ section. + + +Creating Patches +---------------- + +It is possible to send patches directly from git but for new contributors it is recommended to generate the +patches with ``git format-patch`` and then when everything looks okay, and the patches have been checked, to +send them with ``git send-email``. + +Here are some examples of using ``git format-patch`` to generate patches: + +.. code-block:: console + + # Generate a patch from the last commit. + git format-patch -1 + + # Generate a patch from the last 3 commits. + git format-patch -3 + + # Generate the patches in a directory. + git format-patch -3 -o ~/patch/ + + # Add a cover letter to explain a patchset. + git format-patch -3 -o ~/patch/ --cover-letter + + # Add a prefix with a version number. + git format-patch -3 -o ~/patch/ -v 2 + + +Cover letters are useful for explaining a patchset and help to generate a logical threading to the patches. +Smaller notes can be put inline in the patch after the ``---`` separator, for example:: + + Subject: [PATCH] fm10k/base: add FM10420 device ids + + Add the device ID for Boulder Rapids and Atwood Channel to enable + drivers to support those devices. + + Signed-off-by: Alex Smith <alex.smith@example.com> + --- + + ADD NOTES HERE. + + drivers/net/fm10k/base/fm10k_api.c | 6 ++++++ + drivers/net/fm10k/base/fm10k_type.h | 6 ++++++ + 2 files changed, 12 insertions(+) + ... + +Version 2 and later of a patchset should also include a short log of the changes so the reviewer knows what has changed. +This can be added to the cover letter or the annotations. +For example:: + + --- + v3: + * Fixed issued with version.map. + + v2: + * Added i40e support. + * Renamed ethdev functions from rte_eth_ieee15888_*() to rte_eth_timesync_*() + since 802.1AS can be supported through the same interfaces. + + +.. _contrib_checkpatch: + +Checking the Patches +-------------------- + +Patches should be checked for formatting and syntax issues using the ``checkpatches.sh`` script in the ``devtools`` +directory of the DPDK repo. +This uses the Linux kernel development tool ``checkpatch.pl`` which can be obtained by cloning, and periodically, +updating the Linux kernel sources. + +The path to the original Linux script must be set in the environment variable ``DPDK_CHECKPATCH_PATH``. +This, and any other configuration variables required by the development tools, are loaded from the following +files, in order of preference:: + + .develconfig + ~/.config/dpdk/devel.config + /etc/dpdk/devel.config. + +Once the environment variable the script can be run as follows:: + + devtools/checkpatches.sh ~/patch/ + +The script usage is:: + + checkpatches.sh [-h] [-q] [-v] [patch1 [patch2] ...]]" + +Where: + +* ``-h``: help, usage. +* ``-q``: quiet. Don't output anything for files without issues. +* ``-v``: verbose. +* ``patchX``: path to one or more patches. + +Then the git logs should be checked using the ``check-git-log.sh`` script. + +The script usage is:: + + check-git-log.sh [range] + +Where the range is a ``git log`` option. + + +.. _contrib_check_compilation: + +Checking Compilation +-------------------- + +Compilation of patches and changes should be tested using the ``test-build.sh`` script in the ``devtools`` +directory of the DPDK repo:: + + devtools/test-build.sh x86_64-native-linuxapp-gcc+next+shared + +The script usage is:: + + test-build.sh [-h] [-jX] [-s] [config1 [config2] ...]] + +Where: + +* ``-h``: help, usage. +* ``-jX``: use X parallel jobs in "make". +* ``-s``: short test with only first config and without examples/doc. +* ``config``: default config name plus config switches delimited with a ``+`` sign. + +Examples of configs are:: + + x86_64-native-linuxapp-gcc + x86_64-native-linuxapp-gcc+next+shared + x86_64-native-linuxapp-clang+shared + +The builds can be modified via the following environmental variables: + +* ``DPDK_BUILD_TEST_CONFIGS`` (target1+option1+option2 target2) +* ``DPDK_DEP_CFLAGS`` +* ``DPDK_DEP_LDFLAGS`` +* ``DPDK_DEP_PCAP`` (y/[n]) +* ``DPDK_NOTIFY`` (notify-send) + +These can be set from the command line or in the config files shown above in the :ref:`contrib_checkpatch`. + +The recommended configurations and options to test compilation prior to submitting patches are:: + + x86_64-native-linuxapp-gcc+shared+next + x86_64-native-linuxapp-clang+shared + i686-native-linuxapp-gcc + + export DPDK_DEP_ZLIB=y + export DPDK_DEP_PCAP=y + export DPDK_DEP_SSL=y + + +Sending Patches +--------------- + +Patches should be sent to the mailing list using ``git send-email``. +You can configure an external SMTP with something like the following:: + + [sendemail] + smtpuser = name@domain.com + smtpserver = smtp.domain.com + smtpserverport = 465 + smtpencryption = ssl + +See the `Git send-email <https://git-scm.com/docs/git-send-email>`_ documentation for more details. + +The patches should be sent to ``dev@dpdk.org``. +If the patches are a change to existing files then you should send them TO the maintainer(s) and CC ``dev@dpdk.org``. +The appropriate maintainer can be found in the ``MAINTAINERS`` file:: + + git send-email --to maintainer@some.org --cc dev@dpdk.org 000*.patch + +Script ``get-maintainer.sh`` can be used to select maintainers automatically:: + + git send-email --to-cmd ./devtools/get-maintainer.sh --cc dev@dpdk.org 000*.patch + +New additions can be sent without a maintainer:: + + git send-email --to dev@dpdk.org 000*.patch + +You can test the emails by sending it to yourself or with the ``--dry-run`` option. + +If the patch is in relation to a previous email thread you can add it to the same thread using the Message ID:: + + git send-email --to dev@dpdk.org --in-reply-to <1234-foo@bar.com> 000*.patch + +The Message ID can be found in the raw text of emails or at the top of each Patchwork patch, +`for example <http://dpdk.org/dev/patchwork/patch/7646/>`_. +Shallow threading (``--thread --no-chain-reply-to``) is preferred for a patch series. + +Once submitted your patches will appear on the mailing list and in Patchwork. + +Experienced committers may send patches directly with ``git send-email`` without the ``git format-patch`` step. +The options ``--annotate`` and ``confirm = always`` are recommended for checking patches before sending. + + +The Review Process +------------------ + +Patches are reviewed by the community, relying on the experience and +collaboration of the members to double-check each other's work. There are a +number of ways to indicate that you have checked a patch on the mailing list. + + +Tested, Acked and Reviewed by +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +To indicate that you have interacted with a patch on the mailing list you +should respond to the patch in an email with one of the following tags: + + * Reviewed-by: + * Acked-by: + * Tested-by: + * Reported-by: + * Suggested-by: + +The tag should be on a separate line as follows:: + + tag-here: Name Surname <email@address.com> + +Each of these tags has a specific meaning. In general, the DPDK community +follows the kernel usage of the tags. A short summary of the meanings of each +tag is given here for reference: + +.. _statement: https://www.kernel.org/doc/html/latest/process/submitting-patches.html#reviewer-s-statement-of-oversight + +``Reviewed-by:`` is a strong statement_ that the patch is an appropriate state +for merging without any remaining serious technical issues. Reviews from +community members who are known to understand the subject area and to perform +thorough reviews will increase the likelihood of the patch getting merged. + +``Acked-by:`` is a record that the person named was not directly involved in +the preparation of the patch but wishes to signify and record their acceptance +and approval of it. + +``Tested-by:`` indicates that the patch has been successfully tested (in some +environment) by the person named. + +``Reported-by:`` is used to acknowledge person who found or reported the bug. + +``Suggested-by:`` indicates that the patch idea was suggested by the named +person. + + + +Steps to getting your patch merged +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The more work you put into the previous steps the easier it will be to get a +patch accepted. The general cycle for patch review and acceptance is: + +#. Submit the patch. + +#. Check the automatic test reports in the coming hours. + +#. Wait for review comments. While you are waiting review some other patches. + +#. Fix the review comments and submit a ``v n+1`` patchset:: + + git format-patch -3 -v 2 + +#. Update Patchwork to mark your previous patches as "Superseded". + +#. If the patch is deemed suitable for merging by the relevant maintainer(s) or other developers they will ``ack`` + the patch with an email that includes something like:: + + Acked-by: Alex Smith <alex.smith@example.com> + + **Note**: When acking patches please remove as much of the text of the patch email as possible. + It is generally best to delete everything after the ``Signed-off-by:`` line. + +#. Having the patch ``Reviewed-by:`` and/or ``Tested-by:`` will also help the patch to be accepted. + +#. If the patch isn't deemed suitable based on being out of scope or conflicting with existing functionality + it may receive a ``nack``. + In this case you will need to make a more convincing technical argument in favor of your patches. + +#. In addition a patch will not be accepted if it doesn't address comments from a previous version with fixes or + valid arguments. + +#. It is the responsibility of a maintainer to ensure that patches are reviewed and to provide an ``ack`` or + ``nack`` of those patches as appropriate. + +#. Once a patch has been acked by the relevant maintainer, reviewers may still comment on it for a further + two weeks. After that time, the patch should be merged into the relevant git tree for the next release. + Additional notes and restrictions: + + * Patches should be acked by a maintainer at least two days before the release merge + deadline, in order to make that release. + * For patches acked with less than two weeks to go to the merge deadline, all additional + comments should be made no later than two days before the merge deadline. + * After the appropriate time for additional feedback has passed, if the patch has not yet + been merged to the relevant tree by the committer, it should be treated as though it had, + in that any additional changes needed to it must be addressed by a follow-on patch, rather + than rework of the original. + * Trivial patches may be merged sooner than described above at the tree committer's + discretion. + +DPDK Maintainers +---------------- + +The following are the DPDK maintainers as listed in the ``MAINTAINERS`` file +in the DPDK root directory. + +.. literalinclude:: ../../../MAINTAINERS + :lines: 3- diff --git a/dpdk/doc/guides/contributing/stable.rst b/dpdk/doc/guides/contributing/stable.rst new file mode 100644 index 0000000..0f2f1f3 --- /dev/null +++ b/dpdk/doc/guides/contributing/stable.rst @@ -0,0 +1,99 @@ +.. stable_lts_releases: + +DPDK Stable Releases and Long Term Support +========================================== + +This section sets out the guidelines for the DPDK Stable Releases and the DPDK +Long Term Support releases (LTS). + + +Introduction +------------ + +The purpose of the DPDK Stable Releases is to maintain releases of DPDK with +backported fixes over an extended period of time. This provides downstream +consumers of DPDK with a stable target on which to base applications or +packages. + +The Long Term Support release (LTS) is a designation applied to a Stable +Release to indicate longer term support. + + +Stable Releases +--------------- + +Any major release of DPDK can be designated as a Stable Release if a +maintainer volunteers to maintain it. + +A Stable Release is used to backport fixes from an ``N`` release back to an +``N-1`` release, for example, from 16.11 to 16.07. + +The duration of a stable is one complete release cycle (3 months). It can be +longer, up to 1 year, if a maintainer continues to support the stable branch, +or if users supply backported fixes, however the explicit commitment should be +for one release cycle. + +The release cadence is determined by the maintainer based on the number of +bugfixes and the criticality of the bugs. Releases should be coordinated with +the validation engineers to ensure that a tagged release has been tested. + + +LTS Release +----------- + +A stable release can be designated as an LTS release based on community +agreement and a commitment from a maintainer. The current policy is that each +year's November release will be maintained as an LTS for 2 years. + +The current DPDK LTS releases are 16.11 and 17.11. + +It is anticipated that there will be at least 4 releases per year of the LTS +or approximately 1 every 3 months. However, the cadence can be shorter or +longer depending on the number and criticality of the backported +fixes.

Whenever possible, ABI should be preserved +#. Libraries or APIs marked in ``experimental`` state may change without constraint. +#. New APIs will be marked as ``experimental`` for at least one release to allow + any issues found by users of the new API to be fixed quickly +#. The addition of symbols is generally not problematic +#. The modification of symbols can generally be managed with versioning +#. The removal of symbols generally is an ABI break and requires bumping of the + LIBABIVER macro +#. Updates to the minimum hardware requirements, which drop support for hardware which + was previously supported, should be treated as an ABI change. + +What is an ABI +-------------- + +An ABI (Application Binary Interface) is the set of runtime interfaces exposed +by a library. It is similar to an API (Application Programming Interface) but +is the result of compilation. It is also effectively cloned when applications +link to dynamic libraries. That is to say when an application is compiled to +link against dynamic libraries, it is assumed that the ABI remains constant +between the time the application is compiled/linked, and the time that it runs. +Therefore, in the case of dynamic linking, it is critical that an ABI is +preserved, or (when modified), done in such a way that the application is unable +to behave improperly or in an unexpected fashion. + +The DPDK ABI policy +------------------- + +ABI versions are set at the time of major release labeling, and the ABI may +change multiple times, without warning, between the last release label and the +HEAD label of the git tree. + +APIs marked as ``experimental`` are not considered part of the ABI and may +change without warning at any time. Since changes to APIs are most likely +immediately after their introduction, as users begin to take advantage of +those new APIs and start finding issues with them, new DPDK APIs will be +automatically marked as ``experimental`` to allow for a period of stabilization +before they become part of a tracked ABI. + +Note that marking an API as experimental is a multi step process. +To mark an API as experimental, the symbols which are desired to be exported +must be placed in an EXPERIMENTAL version block in the corresponding libraries' +version map script. +Secondly, the corresponding definitions of those exported functions, and +their forward declarations (in the development header files), must be marked +with the ``__rte_experimental`` tag (see ``rte_compat.h``). +The DPDK build makefiles perform a check to ensure that the map file and the +C code reflect the same list of symbols. +This check can be circumvented by defining ``ALLOW_EXPERIMENTAL_API`` +during compilation in the corresponding library Makefile. + +In addition to tagging the code with ``__rte_experimental``, +the doxygen markup must also contain the EXPERIMENTAL string, +and the MAINTAINERS file should note the EXPERIMENTAL libraries. + +ABI versions, once released, are available until such time as their +deprecation has been noted in the Release Notes for at least one major release +cycle. For example consider the case where the ABI for DPDK 2.0 has been +shipped and then a decision is made to modify it during the development of +DPDK 2.1. The decision will be recorded in the Release Notes for the DPDK 2.1 +release and the modification will be made available in the DPDK 2.2 release. + +ABI versions may be deprecated in whole or in part as needed by a given +update. + +Some ABI changes may be too significant to reasonably maintain multiple +versions. In those cases ABI's may be updated without backward compatibility +being provided. The requirements for doing so are: + +#. At least 3 acknowledgments of the need to do so must be made on the + dpdk.org mailing list. + + - The acknowledgment of the maintainer of the component is mandatory, or if + no maintainer is available for the component, the tree/sub-tree maintainer + for that component must acknowledge the ABI change instead. + + - It is also recommended that acknowledgments from different "areas of + interest" be sought for each deprecation, for example: from NIC vendors, + CPU vendors, end-users, etc. + +#. The changes (including an alternative map file) must be gated with + the ``RTE_NEXT_ABI`` option, and provided with a deprecation notice at the + same time. + It will become the default ABI in the next release. + +#. A full deprecation cycle, as explained above, must be made to offer + downstream consumers sufficient warning of the change. + +#. At the beginning of the next release cycle, every ``RTE_NEXT_ABI`` + conditions will be removed, the ``LIBABIVER`` variable in the makefile(s) + where the ABI is changed will be incremented, and the map files will + be updated. + +Note that the above process for ABI deprecation should not be undertaken +lightly. ABI stability is extremely important for downstream consumers of the +DPDK, especially when distributed in shared object form. Every effort should +be made to preserve the ABI whenever possible. The ABI should only be changed +for significant reasons, such as performance enhancements. ABI breakage due to +changes such as reorganizing public structure fields for aesthetic or +readability purposes should be avoided. + +.. note:: + + Updates to the minimum hardware requirements, which drop support for hardware + which was previously supported, should be treated as an ABI change, and + follow the relevant deprecation policy procedures as above: 3 acks and + announcement at least one release in advance. + +Examples of Deprecation Notices +------------------------------- + +The following are some examples of ABI deprecation notices which would be +added to the Release Notes: + +* The Macro ``#RTE_FOO`` is deprecated and will be removed with version 2.0, + to be replaced with the inline function ``rte_foo()``. + +* The function ``rte_mbuf_grok()`` has been updated to include a new parameter + in version 2.0. Backwards compatibility will be maintained for this function + until the release of version 2.1 + +* The members of ``struct rte_foo`` have been reorganized in release 2.0 for + performance reasons. Existing binary applications will have backwards + compatibility in release 2.0, while newly built binaries will need to + reference the new structure variant ``struct rte_foo2``. Compatibility will + be removed in release 2.2, and all applications will require updating and + rebuilding to the new structure at that time, which will be renamed to the + original ``struct rte_foo``. + +* Significant ABI changes are planned for the ``librte_dostuff`` library. The + upcoming release 2.0 will not contain these changes, but release 2.1 will, + and no backwards compatibility is planned due to the extensive nature of + these changes. Binaries using this library built prior to version 2.1 will + require updating and recompilation. + +Versioning Macros +----------------- + +When a symbol is exported from a library to provide an API, it also provides a +calling convention (ABI) that is embodied in its name, return type and +arguments. Occasionally that function may need to change to accommodate new +functionality or behavior. When that occurs, it is desirable to allow for +backward compatibility for a time with older binaries that are dynamically +linked to the DPDK. + +To support backward compatibility the ``lib/librte_compat/rte_compat.h`` +header file provides macros to use when updating exported functions. These +macros are used in conjunction with the ``rte_<library>_version.map`` file for +a given library to allow multiple versions of a symbol to exist in a shared +library so that older binaries need not be immediately recompiled. + +The macros exported are: + +* ``VERSION_SYMBOL(b, e, n)``: Creates a symbol version table entry binding + versioned symbol ``b@DPDK_n`` to the internal function ``b_e``. + +* ``BIND_DEFAULT_SYMBOL(b, e, n)``: Creates a symbol version entry instructing + the linker to bind references to symbol ``b`` to the internal symbol + ``b_e``. + +* ``MAP_STATIC_SYMBOL(f, p)``: Declare the prototype ``f``, and map it to the + fully qualified function ``p``, so that if a symbol becomes versioned, it + can still be mapped back to the public symbol name. + +Setting a Major ABI version +--------------------------- + +Downstreams might want to provide different DPDK releases at the same time to +support multiple consumers of DPDK linked against older and newer sonames. + +Also due to the interdependencies that DPDK libraries can have applications +might end up with an executable space in which multiple versions of a library +are mapped by ld.so. + +Think of LibA that got an ABI bump and LibB that did not get an ABI bump but is +depending on LibA. + +.. note:: + + Application + \-> LibA.old + \-> LibB.new -> LibA.new + +That is a conflict which can be avoided by setting ``CONFIG_RTE_MAJOR_ABI``. +If set, the value of ``CONFIG_RTE_MAJOR_ABI`` overwrites all - otherwise per +library - versions defined in the libraries ``LIBABIVER``. +An example might be ``CONFIG_RTE_MAJOR_ABI=16.11`` which will make all libraries +``librte<?>.so.16.11`` instead of ``librte<?>.so.<LIBABIVER>``. + +Examples of ABI Macro use +------------------------- + +Updating a public API +~~~~~~~~~~~~~~~~~~~~~ + +Assume we have a function as follows + +.. code-block:: c + + /* + * Create an acl context object for apps to + * manipulate + */ + struct rte_acl_ctx * + rte_acl_create(const struct rte_acl_param *param) + { + ... + } + + +Assume that struct rte_acl_ctx is a private structure, and that a developer +wishes to enhance the acl api so that a debugging flag can be enabled on a +per-context basis. This requires an addition to the structure (which, being +private, is safe), but it also requires modifying the code as follows + +.. code-block:: c + + /* + * Create an acl context object for apps to + * manipulate + */ + struct rte_acl_ctx * + rte_acl_create(const struct rte_acl_param *param, int debug) + { + ... + } + + +Note also that, being a public function, the header file prototype must also be +changed, as must all the call sites, to reflect the new ABI footprint. We will +maintain previous ABI versions that are accessible only to previously compiled +binaries + +The addition of a parameter to the function is ABI breaking as the function is +public, and existing application may use it in its current form. However, the +compatibility macros in DPDK allow a developer to use symbol versioning so that +multiple functions can be mapped to the same public symbol based on when an +application was linked to it. To see how this is done, we start with the +requisite libraries version map file. Initially the version map file for the +acl library looks like this + +.. code-block:: none + + DPDK_2.0 { + global: + + rte_acl_add_rules; + rte_acl_build; + rte_acl_classify; + rte_acl_classify_alg; + rte_acl_classify_scalar; + rte_acl_create; + rte_acl_dump; + rte_acl_find_existing; + rte_acl_free; + rte_acl_ipv4vlan_add_rules; + rte_acl_ipv4vlan_build; + rte_acl_list_dump; + rte_acl_reset; + rte_acl_reset_rules; + rte_acl_set_ctx_classify; + + local: *; + }; + +This file needs to be modified as follows + +.. code-block:: none + + DPDK_2.0 { + global: + + rte_acl_add_rules; + rte_acl_build; + rte_acl_classify; + rte_acl_classify_alg; + rte_acl_classify_scalar; + rte_acl_create; + rte_acl_dump; + rte_acl_find_existing; + rte_acl_free; + rte_acl_ipv4vlan_add_rules; + rte_acl_ipv4vlan_build; + rte_acl_list_dump; + rte_acl_reset; + rte_acl_reset_rules; + rte_acl_set_ctx_classify; + + local: *; + }; + + DPDK_2.1 { + global: + rte_acl_create; + + } DPDK_2.0; + +The addition of the new block tells the linker that a new version node is +available (DPDK_2.1), which contains the symbol rte_acl_create, and inherits the +symbols from the DPDK_2.0 node. This list is directly translated into a list of +exported symbols when DPDK is compiled as a shared library + +Next, we need to specify in the code which function map to the rte_acl_create +symbol at which versions. First, at the site of the initial symbol definition, +we need to update the function so that it is uniquely named, and not in conflict +with the public symbol name + +.. code-block:: c + + struct rte_acl_ctx * + -rte_acl_create(const struct rte_acl_param *param) + +rte_acl_create_v20(const struct rte_acl_param *param) + { + size_t sz; + struct rte_acl_ctx *ctx; + ... + +Note that the base name of the symbol was kept intact, as this is conducive to +the macros used for versioning symbols. That is our next step, mapping this new +symbol name to the initial symbol name at version node 2.0. Immediately after +the function, we add this line of code + +.. code-block:: c + + VERSION_SYMBOL(rte_acl_create, _v20, 2.0); + +Remembering to also add the rte_compat.h header to the requisite c file where +these changes are being made. The above macro instructs the linker to create a +new symbol ``rte_acl_create@DPDK_2.0``, which matches the symbol created in older +builds, but now points to the above newly named function. We have now mapped +the original rte_acl_create symbol to the original function (but with a new +name) + +Next, we need to create the 2.1 version of the symbol. We create a new function +name, with a different suffix, and implement it appropriately + +.. code-block:: c + + struct rte_acl_ctx * + rte_acl_create_v21(const struct rte_acl_param *param, int debug); + { + struct rte_acl_ctx *ctx = rte_acl_create_v20(param); + + ctx->debug = debug; + + return ctx; + } + +This code serves as our new API call. Its the same as our old call, but adds +the new parameter in place. Next we need to map this function to the symbol +``rte_acl_create@DPDK_2.1``. To do this, we modify the public prototype of the call +in the header file, adding the macro there to inform all including applications, +that on re-link, the default rte_acl_create symbol should point to this +function. Note that we could do this by simply naming the function above +rte_acl_create, and the linker would chose the most recent version tag to apply +in the version script, but we can also do this in the header file + +.. code-block:: c + + struct rte_acl_ctx * + -rte_acl_create(const struct rte_acl_param *param); + +rte_acl_create(const struct rte_acl_param *param, int debug); + +BIND_DEFAULT_SYMBOL(rte_acl_create, _v21, 2.1); + +The BIND_DEFAULT_SYMBOL macro explicitly tells applications that include this +header, to link to the rte_acl_create_v21 function and apply the DPDK_2.1 +version node to it. This method is more explicit and flexible than just +re-implementing the exact symbol name, and allows for other features (such as +linking to the old symbol version by default, when the new ABI is to be opt-in +for a period. + +One last thing we need to do. Note that we've taken what was a public symbol, +and duplicated it into two uniquely and differently named symbols. We've then +mapped each of those back to the public symbol ``rte_acl_create`` with different +version tags. This only applies to dynamic linking, as static linking has no +notion of versioning. That leaves this code in a position of no longer having a +symbol simply named ``rte_acl_create`` and a static build will fail on that +missing symbol. + +To correct this, we can simply map a function of our choosing back to the public +symbol in the static build with the ``MAP_STATIC_SYMBOL`` macro. Generally the +assumption is that the most recent version of the symbol is the one you want to +map. So, back in the C file where, immediately after ``rte_acl_create_v21`` is +defined, we add this + +.. code-block:: c + + struct rte_acl_ctx * + rte_acl_create_v21(const struct rte_acl_param *param, int debug) + { + ... + } + MAP_STATIC_SYMBOL(struct rte_acl_ctx *rte_acl_create(const struct rte_acl_param *param, int debug), rte_acl_create_v21); + +That tells the compiler that, when building a static library, any calls to the +symbol ``rte_acl_create`` should be linked to ``rte_acl_create_v21`` + +That's it, on the next shared library rebuild, there will be two versions of +rte_acl_create, an old DPDK_2.0 version, used by previously built applications, +and a new DPDK_2.1 version, used by future built applications. + + +Deprecating part of a public API +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Lets assume that you've done the above update, and after a few releases have +passed you decide you would like to retire the old version of the function. +After having gone through the ABI deprecation announcement process, removal is +easy. Start by removing the symbol from the requisite version map file: + +.. code-block:: none + + DPDK_2.0 { + global: + + rte_acl_add_rules; + rte_acl_build; + rte_acl_classify; + rte_acl_classify_alg; + rte_acl_classify_scalar; + rte_acl_dump; + - rte_acl_create + rte_acl_find_existing; + rte_acl_free; + rte_acl_ipv4vlan_add_rules; + rte_acl_ipv4vlan_build; + rte_acl_list_dump; + rte_acl_reset; + rte_acl_reset_rules; + rte_acl_set_ctx_classify; + + local: *; + }; + + DPDK_2.1 { + global: + rte_acl_create; + } DPDK_2.0; + + +Next remove the corresponding versioned export. + +.. code-block:: c + + -VERSION_SYMBOL(rte_acl_create, _v20, 2.0); + + +Note that the internal function definition could also be removed, but its used +in our example by the newer version _v21, so we leave it in place. This is a +coding style choice. + +Lastly, we need to bump the LIBABIVER number for this library in the Makefile to +indicate to applications doing dynamic linking that this is a later, and +possibly incompatible library version: + +.. code-block:: c + + -LIBABIVER := 1 + +LIBABIVER := 2 + +Deprecating an entire ABI version +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +While removing a symbol from and ABI may be useful, it is often more practical +to remove an entire version node at once. If a version node completely +specifies an API, then removing part of it, typically makes it incomplete. In +those cases it is better to remove the entire node + +To do this, start by modifying the version map file, such that all symbols from +the node to be removed are merged into the next node in the map + +In the case of our map above, it would transform to look as follows + +.. code-block:: none + + DPDK_2.1 { + global: + + rte_acl_add_rules; + rte_acl_build; + rte_acl_classify; + rte_acl_classify_alg; + rte_acl_classify_scalar; + rte_acl_dump; + rte_acl_create + rte_acl_find_existing; + rte_acl_free; + rte_acl_ipv4vlan_add_rules; + rte_acl_ipv4vlan_build; + rte_acl_list_dump; + rte_acl_reset; + rte_acl_reset_rules; + rte_acl_set_ctx_classify; + + local: *; + }; + +Then any uses of BIND_DEFAULT_SYMBOL that pointed to the old node should be +updated to point to the new version node in any header files for all affected +symbols. + +.. code-block:: c + + -BIND_DEFAULT_SYMBOL(rte_acl_create, _v20, 2.0); + +BIND_DEFAULT_SYMBOL(rte_acl_create, _v21, 2.1); + +Lastly, any VERSION_SYMBOL macros that point to the old version node should be +removed, taking care to keep, where need old code in place to support newer +versions of the symbol. + +Running the ABI Validator +------------------------- + +The ``devtools`` directory in the DPDK source tree contains a utility program, +``validate-abi.sh``, for validating the DPDK ABI based on the Linux `ABI +Compliance Checker +<http://ispras.linuxbase.org/index.php/ABI_compliance_checker>`_. + +This has a dependency on the ``abi-compliance-checker`` and ``and abi-dumper`` +utilities which can be installed via a package manager.

It combines functions previously +implemented in separate modules to create a modular and scalable acceleration +and assurance engine. It also implements block encryption algorithms, stream +cipher algorithms, hashing algorithms, public key algorithms, run-time +integrity checking, and a hardware random number generator. SEC performs +higher-level cryptographic operations than previous NXP cryptographic +accelerators. This provides significant improvement to system level performance. + +DPAA_SEC is one of the hardware resource in DPAA Architecture. More information +on DPAA Architecture is described in :ref:`dpaa_overview`. + +DPAA_SEC PMD is one of DPAA drivers which interacts with QBMAN to create, +configure and destroy the device instance using queue pair with CAAM portal. + +DPAA_SEC PMD also uses some of the other hardware resources like buffer pools, +queues, queue portals to store and to enqueue/dequeue data to the hardware SEC. + +Implementation +-------------- + +SEC provides platform assurance by working with SecMon, which is a companion +logic block that tracks the security state of the SOC. SEC is programmed by +means of descriptors (not to be confused with frame descriptors (FDs)) that +indicate the operations to be performed and link to the message and +associated data. SEC incorporates two DMA engines to fetch the descriptors, +read the message data, and write the results of the operations.

This value may be overwritten internally if there are too + many devices are attached. + +* slave: If a cryptodev has been initialized with specific name, it can be + attached to the scheduler using this parameter, simply filling the name + here. Multiple cryptodevs can be attached initially by presenting this + parameter multiple times. + +* mode: Specify the scheduling mode of the PMD. The supported scheduling + mode parameter values are specified in the "Cryptodev Scheduler Modes + Overview" section. + +* ordering: Specify the status of the crypto operations ordering feature. + The value of this parameter can be "enable" or "disable".

Also, to configure the + scheduler in the run-time, like attach/detach slave(s), change + scheduling mode, or enable/disable crypto op ordering, one should stop + the scheduler first, otherwise an error will be returned. + + * The crypto op reordering feature requires using the userdata field of + every mbuf to be processed to store temporary data. By the end of + processing, the field is set to pointing to NULL, any previously + stored value of this field will be lost. + + +Cryptodev Scheduler Modes Overview +---------------------------------- + +Currently the Crypto Scheduler PMD library supports following modes of +operation: + +* **CDEV_SCHED_MODE_ROUNDROBIN:** + + *Initialization mode parameter*: **round-robin** + + Round-robin mode, which distributes the enqueued burst of crypto ops + among its slaves in a round-robin manner. This mode may help to fill + the throughput gap between the physical core and the existing cryptodevs + to increase the overall performance. + +* **CDEV_SCHED_MODE_PKT_SIZE_DISTR:** + + *Initialization mode parameter*: **packet-size-distr** + + Packet-size based distribution mode, which works with 2 slaves, the primary + slave and the secondary slave, and distributes the enqueued crypto + operations to them based on their data lengths. A crypto operation will be + distributed to the primary slave if its data length is equal to or bigger + than the designated threshold, otherwise it will be handled by the secondary + slave. + + A typical usecase in this mode is with the QAT cryptodev as the primary and + a software cryptodev as the secondary slave. This may help applications to + process additional crypto workload than what the QAT cryptodev can handle on + its own, by making use of the available CPU cycles to deal with smaller + crypto workloads. + + The threshold is set to 128 bytes by default. It can be updated by calling + function **rte_cryptodev_scheduler_option_set**. The parameter of + **option_type** must be **CDEV_SCHED_OPTION_THRESHOLD** and **option** should + point to a rte_cryptodev_scheduler_threshold_option structure filled with + appropriate threshold value. Please NOTE this threshold has be a power-of-2 + unsigned integer. + +* **CDEV_SCHED_MODE_FAILOVER:** + + *Initialization mode parameter*: **fail-over** + + Fail-over mode, which works with 2 slaves, the primary slave and the + secondary slave. In this mode, the scheduler will enqueue the incoming + crypto operation burst to the primary slave. When one or more crypto + operations fail to be enqueued, then they will be enqueued to the secondary + slave. + +* **CDEV_SCHED_MODE_MULTICORE:** + + *Initialization mode parameter*: **multi-core** + + Multi-core mode, which distributes the workload with several (up to eight) + worker cores. The enqueued bursts are distributed among the worker cores in a + round-robin manner. If scheduler cannot enqueue entire burst to the same worker, + it will enqueue the remaining operations to the next available worker. + For pure small packet size (64 bytes) traffic however the multi-core mode is not + an optimal solution, as it doesn't give significant per-core performance improvement. + For mixed traffic (IMIX) the optimal number of worker cores is around 2-3. + For large packets (1.5 Kbytes) scheduler shows linear scaling in performance + up to eight cores. + Each worker uses its own slave cryptodev.

Therefore, allocated huge pages may not be on socket 0. +To request memory to be reserved on a specific socket, please use the --socket-mem command-line parameter instead of -m. + + +I am running a 32-bit DPDK application on a NUMA system, and sometimes the application initializes fine but cannot allocate memory. Why is that happening? +---------------------------------------------------------------------------------------------------------------------------------------------------------- + +32-bit applications have limitations in terms of how much virtual memory is available, hence the number of hugepages they are able to allocate is also limited (1 GB size). +If your system has a lot (>1 GB size) of hugepage memory, not all of it will be allocated. +Due to hugepages typically being allocated on a local NUMA node, the hugepages allocation the application gets during the initialization depends on which +NUMA node it is running on (the EAL does not affinitize cores until much later in the initialization process). +Sometimes, the Linux OS runs the DPDK application on a core that is located on a different NUMA node from DPDK master core and +therefore all the hugepages are allocated on the wrong socket. + +To avoid this scenario, either lower the amount of hugepage memory available to 1 GB size (or less), or run the application with taskset +affinitizing the application to a would-be master core. + +For example, if your EAL coremask is 0xff0, the master core will usually be the first core in the coremask (0x10); this is what you have to supply to taskset:: + + taskset 0x10 ./l2fwd -l 4-11 -n 2 + +.. Note: Instead of '-c 0xff0' use the '-l 4-11' as a cleaner way to define lcores. + +In this way, the hugepages have a greater chance of being allocated to the correct socket. +Additionally, a ``--socket-mem`` option could be used to ensure the availability of memory for each socket, so that if hugepages were allocated on +the wrong socket, the application simply will not start. + + +On application startup, there is a lot of EAL information printed. Is there any way to reduce this? +--------------------------------------------------------------------------------------------------- + +Yes, the option ``--log-level=`` accepts one of these numbers: + +.. code-block:: c + + #define RTE_LOG_EMERG 1U /* System is unusable. */ + #define RTE_LOG_ALERT 2U /* Action must be taken immediately. */ + #define RTE_LOG_CRIT 3U /* Critical conditions. */ + #define RTE_LOG_ERR 4U /* Error conditions. */ + #define RTE_LOG_WARNING 5U /* Warning conditions. */ + #define RTE_LOG_NOTICE 6U /* Normal but significant condition. */ + #define RTE_LOG_INFO 7U /* Informational. */ + #define RTE_LOG_DEBUG 8U /* Debug-level messages. */ + + +How can I tune my network application to achieve lower latency? +--------------------------------------------------------------- + +Traditionally, there is a trade-off between throughput and latency. An application can be tuned to achieve a high throughput, +but the end-to-end latency of an average packet typically increases as a result. +Similarly, the application can be tuned to have, on average, a low end-to-end latency at the cost of lower throughput. + +To achieve higher throughput, the DPDK attempts to aggregate the cost of processing each packet individually by processing packets in bursts. +Using the testpmd application as an example, the "burst" size can be set on the command line to a value of 32 (also the default value). +This allows the application to request 32 packets at a time from the PMD. +The testpmd application then immediately attempts to transmit all the packets that were received, in this case, all 32 packets. +The packets are not transmitted until the tail pointer is updated on the corresponding TX queue of the network port. +This behavior is desirable when tuning for high throughput because the cost of tail pointer updates to both the RX and TX queues +can be spread across 32 packets, effectively hiding the relatively slow MMIO cost of writing to the PCIe* device. + +However, this is not very desirable when tuning for low latency, because the first packet that was received must also wait for the other 31 packets to be received. +It cannot be transmitted until the other 31 packets have also been processed because the NIC will not know to transmit the packets until the TX tail pointer has been updated, +which is not done until all 32 packets have been processed for transmission. + +To consistently achieve low latency even under heavy system load, the application developer should avoid processing packets in bunches. +The testpmd application can be configured from the command line to use a burst value of 1. +This allows a single packet to be processed at a time, providing lower latency, but with the added cost of lower throughput. + + +Without NUMA enabled, my network throughput is low, why? +-------------------------------------------------------- + +I have a dual Intel® Xeon® E5645 processors 2.40 GHz with four Intel® 82599 10 Gigabit Ethernet NICs. +Using eight logical cores on each processor with RSS set to distribute network load from two 10 GbE interfaces to the cores on each processor. + +Without NUMA enabled, memory is allocated from both sockets, since memory is interleaved. +Therefore, each 64B chunk is interleaved across both memory domains. + +The first 64B chunk is mapped to node 0, the second 64B chunk is mapped to node 1, the third to node 0, the fourth to node 1. +If you allocated 256B, you would get memory that looks like this: + +.. code-block:: console + + 256B buffer + Offset 0x00 - Node 0 + Offset 0x40 - Node 1 + Offset 0x80 - Node 0 + Offset 0xc0 - Node 1 + +Therefore, packet buffers and descriptor rings are allocated from both memory domains, thus incurring QPI bandwidth accessing the other memory and much higher latency. +For best performance with NUMA disabled, only one socket should be populated. + + +I am getting errors about not being able to open files. Why? +------------------------------------------------------------ + +As the DPDK operates, it opens a lot of files, which can result in reaching the open files limits, which is set using the ulimit command or in the limits.conf file. +This is especially true when using a large number (>512) of 2 MB huge pages. Please increase the open file limit if your application is not able to open files. +This can be done either by issuing a ulimit command or editing the limits.conf file. Please consult Linux manpages for usage information. + + +VF driver for IXGBE devices cannot be initialized +------------------------------------------------- + +Some versions of Linux IXGBE driver do not assign a random MAC address to VF devices at initialization. +In this case, this has to be done manually on the VM host, using the following command: + +.. code-block:: console + + ip link set vf mac + +where being the interface providing the virtual functions for example, eth0, being the virtual function number, for example 0, +and being the desired MAC address. + + +Is it safe to add an entry to the hash table while running? +------------------------------------------------------------ +Currently the table implementation is not a thread safe implementation and assumes that locking between threads and processes is handled by the user's application. +This is likely to be supported in future releases. + + +What is the purpose of setting iommu=pt? +---------------------------------------- +DPDK uses a 1:1 mapping and does not support IOMMU. IOMMU allows for simpler VM physical address translation. +The second role of IOMMU is to allow protection from unwanted memory access by an unsafe device that has DMA privileges. +Unfortunately, the protection comes with an extremely high performance cost for high speed NICs. + +Setting ``iommu=pt`` disables IOMMU support for the hypervisor. + + +When trying to send packets from an application to itself, meaning smac==dmac, using Intel(R) 82599 VF packets are lost. +------------------------------------------------------------------------------------------------------------------------ + +Check on register ``LLE(PFVMTXSSW[n])``, which allows an individual pool to send traffic and have it looped back to itself. + + +Can I split packet RX to use DPDK and have an application's higher order functions continue using Linux pthread? +---------------------------------------------------------------------------------------------------------------- + +The DPDK's lcore threads are Linux pthreads bound onto specific cores. Configure the DPDK to do work on the same +cores and run the application's other work on other cores using the DPDK's "coremask" setting to specify which +cores it should launch itself on. + + +Is it possible to exchange data between DPDK processes and regular userspace processes via some shared memory or IPC mechanism? +------------------------------------------------------------------------------------------------------------------------------- + +Yes - DPDK processes are regular Linux/BSD processes, and can use all OS provided IPC mechanisms. + + +Can the multiple queues in Intel(R) I350 be used with DPDK? +----------------------------------------------------------- + +I350 has RSS support and 8 queue pairs can be used in RSS mode. It should work with multi-queue DPDK applications using RSS. + + +How can hugepage-backed memory be shared among multiple processes? +------------------------------------------------------------------ + +See the Primary and Secondary examples in the :ref:`multi-process sample application `. + + +Why can't my application receive packets on my system with UEFI Secure Boot enabled? +------------------------------------------------------------------------------------ + +If UEFI secure boot is enabled, the Linux kernel may disallow the use of UIO on the system. +Therefore, devices for use by DPDK should be bound to the ``vfio-pci`` kernel module rather than ``igb_uio`` or ``uio_pci_generic``. diff --git a/dpdk/doc/guides/faq/index.rst b/dpdk/doc/guides/faq/index.rst new file mode 100644 index 0000000..a9ae9bd --- /dev/null +++ b/dpdk/doc/guides/faq/index.rst @@ -0,0 +1,13 @@ +..

The installation of these tools is covered in this +section. + +Compiling the DPDK requires the FreeBSD kernel sources, which should be +included during the installation of FreeBSD on the development platform. +The DPDK also requires the use of FreeBSD ports to compile and function. + +To use the FreeBSD ports system, it is required to update and extract the FreeBSD +ports tree by issuing the following commands: + +.. code-block:: console + + portsnap fetch + portsnap extract + +If the environment requires proxies for external communication, these can be set +using: + +.. code-block:: console + + setenv http_proxy : + setenv ftp_proxy : + +The FreeBSD ports below need to be installed prior to building the DPDK. +In general these can be installed using the following set of commands:: + + cd /usr/ports/ + + make config-recursive + + make install + + make clean + +Each port location can be found using:: + + whereis + +The ports required and their locations are as follows: + +* dialog4ports: ``/usr/ports/ports-mgmt/dialog4ports`` + +* GNU make(gmake): ``/usr/ports/devel/gmake`` + +* coreutils: ``/usr/ports/sysutils/coreutils`` + +For compiling and using the DPDK with gcc, the compiler must be installed +from the ports collection: + +* gcc: version 4.9 is recommended ``/usr/ports/lang/gcc49``. + Ensure that ``CPU_OPTS`` is selected (default is OFF). + +When running the make config-recursive command, a dialog may be presented to the +user.

For more information on this setting, and its + possible values, see the *DPDK Programmers Guide*. + +To make the target, use ``gmake install T=``. + +For example to compile for FreeBSD use: + +.. code-block:: console + + gmake install T=x86_64-native-bsdapp-clang + +.. note:: + + If the compiler binary to be used does not correspond to that given in the + TOOLCHAIN part of the target, the compiler command may need to be explicitly + specified. For example, if compiling for gcc, where the gcc binary is called + gcc4.9, the command would need to be ``gmake install T= CC=gcc4.9``. + +Browsing the Installed DPDK Environment Target +---------------------------------------------- + +Once a target is created, it contains all the libraries and header files for the +DPDK environment that are required to build customer applications. +In addition, the test and testpmd applications are built under the build/app +directory, which may be used for testing. A kmod directory is also present that +contains the kernel modules to install. + +.. _loading_contigmem: + +Loading the DPDK contigmem Module +--------------------------------- + +To run a DPDK application, physically contiguous memory is required. +In the absence of non-transparent superpages, the included sources for the +contigmem kernel module provides the ability to present contiguous blocks of +memory for the DPDK to use. The contigmem module must be loaded into the +running kernel before any DPDK is run. The module is found in the kmod +sub-directory of the DPDK target directory. + +The amount of physically contiguous memory along with the number of physically +contiguous blocks to be reserved by the module can be set at runtime prior to +module loading using: + +.. code-block:: console + + kenv hw.contigmem.num_buffers=n + kenv hw.contigmem.buffer_size=m + +The kernel environment variables can also be specified during boot by placing the +following in ``/boot/loader.conf``:: + + hw.contigmem.num_buffers=n hw.contigmem.buffer_size=m + +The variables can be inspected using the following command: + +.. code-block:: console + + sysctl -a hw.contigmem + +Where n is the number of blocks and m is the size in bytes of each area of +contiguous memory. A default of two buffers of size 1073741824 bytes (1 Gigabyte) +each is set during module load if they are not specified in the environment. + +The module can then be loaded using kldload (assuming that the current directory +is the DPDK target directory): + +.. code-block:: console + + kldload ./kmod/contigmem.ko + +It is advisable to include the loading of the contigmem module during the boot +process to avoid issues with potential memory fragmentation during later system +up time. This can be achieved by copying the module to the ``/boot/kernel/`` +directory and placing the following into ``/boot/loader.conf``:: + + contigmem_load="YES" + +.. note:: + + The contigmem_load directive should be placed after any definitions of + ``hw.contigmem.num_buffers`` and ``hw.contigmem.buffer_size`` if the default values + are not to be used. + +An error such as: + +.. code-block:: console + + kldload: can't load ./x86_64-native-bsdapp-gcc/kmod/contigmem.ko: + Exec format error + +is generally attributed to not having enough contiguous memory +available and can be verified via dmesg or ``/var/log/messages``: + +.. code-block:: console + + kernel: contigmalloc failed for buffer + +To avoid this error, reduce the number of buffers or the buffer size. + +.. _loading_nic_uio: + +Loading the DPDK nic_uio Module +------------------------------- + +After loading the contigmem module, the ``nic_uio`` module must also be loaded into the +running kernel prior to running any DPDK application. This module must +be loaded using the kldload command as shown below (assuming that the current +directory is the DPDK target directory). + +.. code-block:: console + + kldload ./kmod/nic_uio.ko + +.. note:: + + If the ports to be used are currently bound to a existing kernel driver + then the ``hw.nic_uio.bdfs sysctl`` value will need to be set before loading the + module. Setting this value is described in the next section below. + +Currently loaded modules can be seen by using the ``kldstat`` command and a module +can be removed from the running kernel by using ``kldunload ``. + +To load the module during boot, copy the ``nic_uio`` module to ``/boot/kernel`` +and place the following into ``/boot/loader.conf``:: + + nic_uio_load="YES" + +.. note:: + + ``nic_uio_load="YES"`` must appear after the contigmem_load directive, if it exists. + +By default, the ``nic_uio`` module will take ownership of network ports if they are +recognized DPDK devices and are not owned by another module. However, since +the FreeBSD kernel includes support, either built-in, or via a separate driver +module, for most network card devices, it is likely that the ports to be used are +already bound to a driver other than ``nic_uio``. The following sub-section describe +how to query and modify the device ownership of the ports to be used by +DPDK applications. + +.. _binding_network_ports: + +Binding Network Ports to the nic_uio Module +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Device ownership can be viewed using the pciconf -l command.

Device name: ``ixN`` + +#. Unit name: ``pci0`` + +#. Selector (Bus:Device:Function): ``1:0:0`` + +Where no driver is associated with a device, the device name will be ``none``. + +By default, the FreeBSD kernel will include built-in drivers for the most common +devices; a kernel rebuild would normally be required to either remove the drivers +or configure them as loadable modules. + +To avoid building a custom kernel, the ``nic_uio`` module can detach a network port +from its current device driver.

To do so, unload both the target kernel module and the +``nic_uio`` module, modify or clear the ``hw.nic_uio.bdfs`` kernel environment (kenv) +value, and reload the two drivers - first the original kernel driver, and then +the ``nic_uio driver``. Note: the latter does not need to be reloaded unless there are +ports that are still to be bound to it. + +Example commands to perform these steps are shown below: + +.. code-block:: console + + kldunload nic_uio + kldunload + + # To clear the value completely: + kenv -u hw.nic_uio.bdfs + + # To update the list of ports to bind: + kenv hw.nic_uio.bdfs="b:d:f,b:d:f,..." + + kldload + + kldload nic_uio # optional diff --git a/dpdk/doc/guides/freebsd_gsg/build_sample_apps.rst b/dpdk/doc/guides/freebsd_gsg/build_sample_apps.rst new file mode 100644 index 0000000..90f0502 --- /dev/null +++ b/dpdk/doc/guides/freebsd_gsg/build_sample_apps.rst @@ -0,0 +1,182 @@ +..

SPDX-License-Identifier: BSD-3-Clause + Copyright(c) 2016 Intel Corporation. + +Flow Bifurcation How-to Guide +============================= + +Flow Bifurcation is a mechanism which uses hardware capable Ethernet devices +to split traffic between Linux user space and kernel space. Since it is a +hardware assisted feature this approach can provide line rate processing +capability. Other than :ref:`KNI `, the software is just required to +enable device configuration, there is no need to take care of the packet +movement during the traffic split. This can yield better performance with +less CPU overhead. + +The Flow Bifurcation splits the incoming data traffic to user space +applications (such as DPDK applications) and/or kernel space programs (such as +the Linux kernel stack). It can direct some traffic, for example data plane +traffic, to DPDK, while directing some other traffic, for example control +plane traffic, to the traditional Linux networking stack. + +There are a number of technical options to achieve this. A typical example is +to combine the technology of SR-IOV and packet classification filtering. + +SR-IOV is a PCI standard that allows the same physical adapter to be split as +multiple virtual functions. Each virtual function (VF) has separated queues +with physical functions (PF). The network adapter will direct traffic to a +virtual function with a matching destination MAC address. In a sense, SR-IOV +has the capability for queue division. + +Packet classification filtering is a hardware capability available on most +network adapters. Filters can be configured to direct specific flows to a +given receive queue by hardware. Different NICs may have different filter +types to direct flows to a Virtual Function or a queue that belong to it. + +In this way the Linux networking stack can receive specific traffic through +the kernel driver while a DPDK application can receive specific traffic +bypassing the Linux kernel by using drivers like VFIO or the DPDK ``igb_uio`` +module. + +.. _figure_flow_bifurcation_overview: + +.. figure:: img/flow_bifurcation_overview.* + + Flow Bifurcation Overview + + +Using Flow Bifurcation on IXGBE in Linux +---------------------------------------- + +On Intel 82599 10 Gigabit Ethernet Controller series NICs Flow Bifurcation can +be achieved by SR-IOV and Intel Flow Director technologies. Traffic can be +directed to queues by the Flow Director capability, typically by matching +5-tuple of UDP/TCP packets. + +The typical procedure to achieve this is as follows: + +#. Boot the system without iommu, or with ``iommu=pt``. + +#. Create Virtual Functions: + + .. code-block:: console + + echo 2 > /sys/bus/pci/devices/0000:01:00.0/sriov_numvfs + +#. Enable and set flow filters: + + .. code-block:: console + + ethtool -K eth1 ntuple on + ethtool -N eth1 flow-type udp4 src-ip 192.0.2.2 dst-ip 198.51.100.2 \ + action $queue_index_in_VF0 + ethtool -N eth1 flow-type udp4 src-ip 198.51.100.2 dst-ip 192.0.2.2 \ + action $queue_index_in_VF1 + + Where: + + * ``$queue_index_in_VFn``: Bits 39:32 of the variable defines VF id + 1; the lower 32 bits indicates the queue index of the VF. Thus: + + * ``$queue_index_in_VF0`` = ``(0x1 & 0xFF) << 32 + [queue index]``. + + * ``$queue_index_in_VF1`` = ``(0x2 & 0xFF) << 32 + [queue index]``. + + .. _figure_ixgbe_bifu_queue_idx: + + .. figure:: img/ixgbe_bifu_queue_idx.* + +#. Compile the DPDK application and insert ``igb_uio`` or probe the ``vfio-pci`` kernel modules as normal. + +#. Bind the virtual functions: + + .. code-block:: console + + modprobe vfio-pci + dpdk-devbind.py -b vfio-pci 01:10.0 + dpdk-devbind.py -b vfio-pci 01:10.1 + +#. Run a DPDK application on the VFs: + + .. code-block:: console + + testpmd -l 0-7 -n 4 -- -i -w 01:10.0 -w 01:10.1 --forward-mode=mac + +In this example, traffic matching the rules will go through the VF by matching +the filter rule. All other traffic, not matching the rules, will go through +the default queue or scaling on queues in the PF. That is to say UDP packets +with the specified IP source and destination addresses will go through the +DPDK application. All other traffic, with different hosts or different +protocols, will go through the Linux networking stack. + +.. note:: + + * The above steps work on the Linux kernel v4.2. + + * The Flow Bifurcation is implemented in Linux kernel and ixgbe kernel driver using the following patches: + + * `ethtool: Add helper routines to pass vf to rx_flow_spec `_ + + * `ixgbe: Allow flow director to use entire queue space `_ + + * The Ethtool version used in this example is 3.18. + + +Using Flow Bifurcation on I40E in Linux +--------------------------------------- + +On Intel X710/XL710 series Ethernet Controllers Flow Bifurcation can be +achieved by SR-IOV, Cloud Filter and L3 VEB switch. The traffic can be +directed to queues by the Cloud Filter and L3 VEB switch's matching rule. + +* L3 VEB filters work for non-tunneled packets. It can direct a packet just by + the Destination IP address to a queue in a VF. + +* Cloud filters work for the following types of tunneled packets. + + * Inner mac. + + * Inner mac + VNI. + + * Outer mac + Inner mac + VNI. + + * Inner mac + Inner vlan + VNI. + + * Inner mac + Inner vlan. + +The typical procedure to achieve this is as follows: + +#. Boot the system without iommu, or with ``iommu=pt``. + +#. Build and insert the ``i40e.ko`` module. + +#. Create Virtual Functions: + + .. code-block:: console + + echo 2 > /sys/bus/pci/devices/0000:01:00.0/sriov_numvfs + +#.

SPDX-License-Identifier: BSD-3-Clause + Copyright(c) 2017 Intel Corporation. + +DPDK pdump Library and pdump Tool +================================= + +This document describes how the Data Plane Development Kit (DPDK) Packet +Capture Framework is used for capturing packets on DPDK ports. It is intended +for users of DPDK who want to know more about the Packet Capture feature and +for those who want to monitor traffic on DPDK-controlled devices. + +The DPDK packet capture framework was introduced in DPDK v16.07. The DPDK +packet capture framework consists of the DPDK pdump library and DPDK pdump +tool. + + +Introduction +------------ + +The :ref:`librte_pdump ` library provides the APIs required to +allow users to initialize the packet capture framework and to enable or +disable packet capture. The library works on a client/server model and its +usage is recommended for debugging purposes. + +The :ref:`dpdk-pdump ` tool is developed based on the +``librte_pdump`` library. It runs as a DPDK secondary process and is capable +of enabling or disabling packet capture on DPDK ports. The ``dpdk-pdump`` tool +provides command-line options with which users can request enabling or +disabling of the packet capture on DPDK ports. + +The application which initializes the packet capture framework will act as a +server and the application that enables or disables the packet capture will +act as a client. The server sends the Rx and Tx packets from the DPDK ports +to the client. + +In DPDK the ``testpmd`` application can be used to initialize the packet +capture framework and act as a server, and the ``dpdk-pdump`` tool acts as a +client. To view Rx or Tx packets of ``testpmd``, the application should be +launched first, and then the ``dpdk-pdump`` tool. Packets from ``testpmd`` +will be sent to the tool, which then sends them on to the Pcap PMD device and +that device writes them to the Pcap file or to an external interface depending +on the command-line option used. + +Some things to note: + +* The ``dpdk-pdump`` tool can only be used in conjunction with a primary + application which has the packet capture framework initialized already. In + dpdk, only ``testpmd`` is modified to initialize packet capture framework, + other applications remain untouched. So, if the ``dpdk-pdump`` tool has to + be used with any application other than the testpmd, the user needs to + explicitly modify that application to call the packet capture framework + initialization code. Refer to the ``app/test-pmd/testpmd.c`` code and look + for ``pdump`` keyword to see how this is done. + +* The ``dpdk-pdump`` tool depends on the libpcap based PMD which is disabled + by default in the build configuration files, owing to an external dependency + on the libpcap development files. Once the libpcap development files are + installed, the libpcap based PMD can be enabled by setting + ``CONFIG_RTE_LIBRTE_PMD_PCAP=y`` and recompiling the DPDK. + + +Test Environment +---------------- + +The overview of using the Packet Capture Framework and the ``dpdk-pdump`` tool +for packet capturing on the DPDK port in +:numref:`figure_packet_capture_framework`. + +.. _figure_packet_capture_framework: + +.. figure:: img/packet_capture_framework.* + + Packet capturing on a DPDK port using the dpdk-pdump tool. + + +Configuration +------------- + +Modify the DPDK primary application to initialize the packet capture framework +as mentioned in the above notes and enable the following config options and +build DPDK:: + + CONFIG_RTE_LIBRTE_PMD_PCAP=y + CONFIG_RTE_LIBRTE_PDUMP=y + + +Running the Application +----------------------- + +The following steps demonstrate how to run the ``dpdk-pdump`` tool to capture +Rx side packets on dpdk_port0 in :numref:`figure_packet_capture_framework` and +inspect them using ``tcpdump``. + +#.

SPDX-License-Identifier: BSD-3-Clause + Copyright(c) 2017 Intel Corporation. + +VF daemon (VFd) +=============== + +VFd (the VF daemon) is a mechanism which can be used to configure features on +a VF (SR-IOV Virtual Function) without direct access to the PF (SR-IOV +Physical Function). VFd is an *EXPERIMENTAL* feature which can only be used in +the scenario of DPDK PF with a DPDK VF. If the PF port is driven by the Linux +kernel driver then the VFd feature will not work. Currently VFd is only +supported by the ixgbe and i40e drivers. + +In general VF features cannot be configured directly by an end user +application since they are under the control of the PF. The normal approach to +configuring a feature on a VF is that an application would call the APIs +provided by the VF driver. If the required feature cannot be configured by the +VF directly (the most common case) the VF sends a message to the PF through +the mailbox on ixgbe and i40e. This means that the availability of the feature +depends on whether the appropriate mailbox messages are defined. + +DPDK leverages the mailbox interface defined by the Linux kernel driver so +that compatibility with the kernel driver can be guaranteed. The downside of +this approach is that the availability of messages supported by the kernel +become a limitation when the user wants to configure features on the VF. + +VFd is a new method of controlling the features on a VF. The VF driver doesn't +talk directly to the PF driver when configuring a feature on the VF. When a VF +application (i.e., an application using the VF ports) wants to enable a VF +feature, it can send a message to the PF application (i.e., the application +using the PF port, which can be the same as the VF application). The PF +application will configure the feature for the VF. Obviously, the PF +application can also configure the VF features without a request from the VF +application. + +.. _VF_daemon_overview: + +.. figure:: img/vf_daemon_overview.* + + VF daemon (VFd) Overview + +Compared with the traditional approach the VFd moves the negotiation between +VF and PF from the driver level to application level. So the application +should define how the negotiation between the VF and PF works, or even if the +control should be limited to the PF. + +It is the application's responsibility to use VFd. Consider for example a KVM +migration, the VF application may transfer from one VM to another. It is +recommended in this case that the PF control the VF features without +participation from the VF. Then the VF application has no capability to +configure the features. So the user doesn't need to define the interface +between the VF application and the PF application. The service provider should +take the control of all the features. + +The following sections describe the VFd functionality. + +.. Note:: + + Although VFd is supported by both ixgbe and i40e, please be aware that + since the hardware capability is different, the functions supported by + ixgbe and i40e are not the same. + + +Preparing +--------- + +VFd only can be used in the scenario of DPDK PF + DPDK VF. Users should bind +the PF port to ``igb_uio``, then create the VFs based on the DPDK PF host. + +The typical procedure to achieve this is as follows: + +#. Boot the system without iommu, or with ``iommu=pt``. + +#. Bind the PF port to ``igb_uio``, for example:: + + dpdk-devbind.py -b igb_uio 01:00.0 + +#. Create a Virtual Function:: + + echo 1 > /sys/bus/pci/devices/0000:01:00.0/max_vfs + +#. Start a VM with the new VF port bypassed to it. + +#.

The device emulation layer by +QEMU in VM's context is saved by just registering a new kind of virtual device +in DPDK's ether layer. And to minimize the change, we reuse already-existing +virtio PMD code (driver/net/virtio/). + +Virtio, in essence, is a shm-based solution to transmit/receive packets. How is +memory shared? In VM's case, qemu always shares the whole physical layout of VM +to vhost backend. But it's not feasible for a container, as a process, to share +all virtual memory regions to backend. So only those virtual memory regions +(aka, hugepages initialized in DPDK) are sent to backend. It restricts that only +addresses in these areas can be used to transmit or receive packets. + +Sample Usage +------------ + +Here we use Docker as container engine.

Currently, DPDK uses anonymous mapping + under this option which cannot be reopened to share with vhost backend. + * Cannot work when there are more than VHOST_MEMORY_MAX_NREGIONS(8) hugepages. + If you have more regions (especially when 2MB hugepages are used), the option, + --single-file-segments, can help to reduce the number of shared files. + * Applications should not use file name like HUGEFILE_FMT ("%smap_%d"). That + will bring confusion when sharing hugepage files with backend by name. + * Root privilege is a must.

See the "Multi-process Sample Application" + chapter in the *DPDK Sample Applications User Guide* and the *DPDK + Programmers Guide* for more details. + +Logical Core Use by Applications +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The coremask (-c 0x0f) or corelist (-l 0-3) parameter is always mandatory for DPDK applications. +Each bit of the mask corresponds to the equivalent logical core number as reported by Linux. The preferred corelist option is a cleaner method to define cores to be used. +Since these logical core numbers, and their mapping to specific cores on specific NUMA sockets, can vary from platform to platform, +it is recommended that the core layout for each platform be considered when choosing the coremask/corelist to use in each case. + +On initialization of the EAL layer by an DPDK application, the logical cores to be used and their socket location are displayed. +This information can also be determined for all cores on the system by examining the ``/proc/cpuinfo`` file, for example, by running cat ``/proc/cpuinfo``. +The physical id attribute listed for each processor indicates the CPU socket to which it belongs. +This can be useful when using other processors to understand the mapping of the logical cores to the sockets. + +.. note:: + + A more graphical view of the logical core layout may be obtained using the ``lstopo`` Linux utility. + On Fedora Linux, this may be installed and run using the following command:: + + sudo yum install hwloc + ./lstopo + +.. warning:: + + The logical core layout can change between different board layouts and should be checked before selecting an application coremask/corelist. + +Hugepage Memory Use by Applications +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +When running an application, it is recommended to use the same amount of memory as that allocated for hugepages. +This is done automatically by the DPDK application at startup, +if no ``-m`` or ``--socket-mem`` parameter is passed to it when run. + +If more memory is requested by explicitly passing a ``-m`` or ``--socket-mem`` value, the application fails. +However, the application itself can also fail if the user requests less memory than the reserved amount of hugepage-memory, particularly if using the ``-m`` option. +The reason is as follows. +Suppose the system has 1024 reserved 2 MB pages in socket 0 and 1024 in socket 1. +If the user requests 128 MB of memory, the 64 pages may not match the constraints: + +* The hugepage memory by be given to the application by the kernel in socket 1 only. + In this case, if the application attempts to create an object, such as a ring or memory pool in socket 0, it fails. + To avoid this issue, it is recommended that the ``--socket-mem`` option be used instead of the ``-m`` option. + +* These pages can be located anywhere in physical memory, and, although the DPDK EAL will attempt to allocate memory in contiguous blocks, + it is possible that the pages will not be contiguous. In this case, the application is not able to allocate big memory pools. + +The socket-mem option can be used to request specific amounts of memory for specific sockets. +This is accomplished by supplying the ``--socket-mem`` flag followed by amounts of memory requested on each socket, +for example, supply ``--socket-mem=0,512`` to try and reserve 512 MB for socket 1 only. +Similarly, on a four socket system, to allocate 1 GB memory on each of sockets 0 and 2 only, the parameter ``--socket-mem=1024,0,1024`` can be used. +No memory will be reserved on any CPU socket that is not explicitly referenced, for example, socket 3 in this case. +If the DPDK cannot allocate enough memory on each socket, the EAL initialization fails. + +Additional Sample Applications +------------------------------ + +Additional sample applications are included in the ${RTE_SDK}/examples directory. +These sample applications may be built and run in a manner similar to that described in earlier sections in this manual. +In addition, see the *DPDK Sample Applications User Guide* for a description of the application, +specific instructions on compilation and execution and some explanation of the code. + +Additional Test Applications +---------------------------- + +In addition, there are two other applications that are built when the libraries are created. +The source files for these are in the DPDK/app directory and are called test and testpmd. +Once the libraries are created, they can be found in the build/app directory. + +* The test application provides a variety of specific tests for the various functions in the DPDK. + +* The testpmd application provides a number of different packet throughput tests and + examples of features such as how to use the Flow Director found in the Intel® 82599 10 Gigabit Ethernet Controller. diff --git a/dpdk/doc/guides/linux_gsg/enable_func.rst b/dpdk/doc/guides/linux_gsg/enable_func.rst new file mode 100644 index 0000000..b2bda80 --- /dev/null +++ b/dpdk/doc/guides/linux_gsg/enable_func.rst @@ -0,0 +1,159 @@ +..

It can +be loaded as shown below: + +.. code-block:: console + + sudo modprobe uio + sudo insmod kmod/igb_uio.ko + +.. note:: + + For some devices which lack support for legacy interrupts, e.g. virtual function + (VF) devices, the ``igb_uio`` module may be needed in place of ``uio_pci_generic``. + +.. note:: + + If UEFI secure boot is enabled, the Linux kernel may disallow the use of + UIO on the system. Therefore, devices for use by DPDK should be bound to the + ``vfio-pci`` kernel module rather than ``igb_uio`` or ``uio_pci_generic``. + For more details see :ref:`linux_gsg_binding_kernel` below. + +Since DPDK release 1.7 onward provides VFIO support, use of UIO is optional +for platforms that support using VFIO. + +VFIO +---- + +A more robust and secure driver in compare to the ``UIO``, relying on IOMMU protection. +To make use of VFIO, the ``vfio-pci`` module must be loaded: + +.. code-block:: console + + sudo modprobe vfio-pci + +Note that in order to use VFIO, your kernel must support it. +VFIO kernel modules have been included in the Linux kernel since version 3.6.0 and are usually present by default, +however please consult your distributions documentation to make sure that is the case. + +Also, to use VFIO, both kernel and BIOS must support and be configured to use IO virtualization (such as Intel® VT-d). + +.. note:: + + ``vfio-pci`` module doesn't support the creation of virtual functions. + +For proper operation of VFIO when running DPDK applications as a non-privileged user, correct permissions should also be set up. +This can be done by using the DPDK setup script (called dpdk-setup.sh and located in the usertools directory). + +.. note:: + + VFIO can be used without IOMMU. While this is just as unsafe as using UIO, it does make it possible for the user to keep the degree of device access and programming that VFIO has, in situations where IOMMU is not available. + +Bifurcated Driver +----------------- + +PMDs which use the bifurcated driver co-exists with the device kernel driver. +On such model the NIC is controlled by the kernel, while the data +path is performed by the PMD directly on top of the device. + +Such model has the following benefits: + + - It is secure and robust, as the memory management and isolation + is done by the kernel. + - It enables the user to use legacy linux tools such as ``ethtool`` or + ``ifconfig`` while running DPDK application on the same network ports. + - It enables the DPDK application to filter only part of the traffic, + While the rest will be directed and handled by the kernel driver. + +More about the bifurcated driver can be found in +`Mellanox Bifurcated DPDK PMD +`__. + +.. _linux_gsg_binding_kernel: + +Binding and Unbinding Network Ports to/from the Kernel Modules +-------------------------------------------------------------- + +.. note:: + + PMDs Which use the bifurcated driver should not be unbind from their kernel drivers. this section is for PMDs which use the UIO or VFIO drivers. + +As of release 1.4, DPDK applications no longer automatically unbind all supported network ports from the kernel driver in use. +Instead, in case the PMD being used use the UIO or VFIO drivers, all ports that are to be used by an DPDK application must be bound to the +``uio_pci_generic``, ``igb_uio`` or ``vfio-pci`` module before the application is run. +For such PMDs, any network ports under Linux* control will be ignored and cannot be used by the application. + +To bind ports to the ``uio_pci_generic``, ``igb_uio`` or ``vfio-pci`` module for DPDK use, +and then subsequently return ports to Linux* control, +a utility script called dpdk-devbind.py is provided in the usertools subdirectory. +This utility can be used to provide a view of the current state of the network ports on the system, +and to bind and unbind those ports from the different kernel modules, including the uio and vfio modules. +The following are some examples of how the script can be used. +A full description of the script and its parameters can be obtained by calling the script with the ``--help`` or ``--usage`` options. +Note that the uio or vfio kernel modules to be used, should be loaded into the kernel before +running the ``dpdk-devbind.py`` script. + +.. warning:: + + Due to the way VFIO works, there are certain limitations to which devices can be used with VFIO. + Mainly it comes down to how IOMMU groups work. + Any Virtual Function device can be used with VFIO on its own, but physical devices will require either all ports bound to VFIO, + or some of them bound to VFIO while others not being bound to anything at all. + + If your device is behind a PCI-to-PCI bridge, the bridge will then be part of the IOMMU group in which your device is in. + Therefore, the bridge driver should also be unbound from the bridge PCI device for VFIO to work with devices behind the bridge. + +.. warning:: + + While any user can run the dpdk-devbind.py script to view the status of the network ports, + binding or unbinding network ports requires root privileges. + +To

+======================================================== + +This document is a step-by-step guide for getting high performance from DPDK applications on Intel platforms. + + +Hardware and Memory Requirements +-------------------------------- + +For best performance use an Intel Xeon class server system such as Ivy Bridge, Haswell or newer. + +Ensure that each memory channel has at least one memory DIMM inserted, and that the memory size for each is at least 4GB. +**Note**: this has one of the most direct effects on performance. + +You can check the memory configuration using

Clock Speed: Unknown + +The output shows a speed of 2133 MHz (DDR4) and Unknown (not existing). +This aligns with the previous output which showed that each channel has one memory bar. + + +Network Interface Card Requirements +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Use a `DPDK supported `_ high end NIC such as the Intel XL710 40GbE. + +Make sure each NIC has been flashed the latest version of NVM/firmware. + +Use PCIe Gen3 slots, such as Gen3 ``x8`` or Gen3 ``x16`` because PCIe Gen2 slots don't provide enough bandwidth +for 2 x 10GbE and above. +You can use ``lspci`` to check the speed of a PCI slot using something like the following:: + + lspci -s 03:00.1 -vv | grep LnkSta + + LnkSta: Speed 8GT/s, Width x8, TrErr- Train- SlotClk+ DLActive- ... + LnkSta2: Current De-emphasis Level: -6dB, EqualizationComplete+ ... + +When inserting NICs into PCI slots always check the caption, such as CPU0 or CPU1 to indicate which socket it is connected to. + +Care should be take with NUMA. +If you are using 2 or more ports from different NICs, it is best to ensure that these NICs are on the same CPU socket. +An example of how to determine this is shown further below. + + +BIOS Settings +~~~~~~~~~~~~~ + +The following are some recommendations on BIOS settings. Different platforms will have different BIOS naming +so the following is mainly for reference: + +#. Before starting consider resetting all BIOS settings to their default. + +#. Disable all power saving options such as: Power performance tuning, CPU P-State, CPU C3 Report and CPU C6 Report. + +#. Select **Performance** as the CPU Power and Performance policy. + +#. Disable Turbo Boost to ensure the performance scaling increases with the number of cores. + +#. Set memory frequency to the highest available number, NOT auto. + +#. Disable all virtualization options when you test the physical function of the NIC, and turn on ``VT-d`` if you wants to use VFIO. + + +Linux boot command line +~~~~~~~~~~~~~~~~~~~~~~~ + +The following are some recommendations on GRUB boot settings: + +#. Use the default grub file as a starting point. + +#. Reserve 1G huge pages via grub configurations. For example to reserve 8 huge pages of 1G size:: + + default_hugepagesz=1G hugepagesz=1G hugepages=8 + +#. Isolate CPU cores which will be used for DPDK. For example:: + + isolcpus=2,3,4,5,6,7,8 + +#. If it wants to use VFIO, use the following additional grub parameters:: + + iommu=pt intel_iommu=on + + +Configurations before running DPDK +---------------------------------- + +1. Build the DPDK target and reserve huge pages. + See the earlier section on :ref:`linux_gsg_hugepages` for more details. + + The following shell commands may help with building and configuration: + + .. code-block:: console + + # Build DPDK target. + cd dpdk_folder + make install T=x86_64-native-linuxapp-gcc -j + + # Get the hugepage size. + awk '/Hugepagesize/ {print $2}' /proc/meminfo + + # Get the total huge page numbers. + awk '/HugePages_Total/ {print $2} ' /proc/meminfo + + # Unmount the hugepages. + umount `awk '/hugetlbfs/ {print $2}' /proc/mounts` + + # Create the hugepage mount folder. + mkdir -p /mnt/huge + + # Mount to the specific folder. + mount -t hugetlbfs nodev /mnt/huge + +2. Check the CPU layout using using the DPDK ``cpu_layout`` utility: + + .. code-block:: console + + cd dpdk_folder + + usertools/cpu_layout.py + + Or run ``lscpu`` to check the cores on each socket. + +3. Check your NIC id and related socket id: + + .. code-block:: console + + # List all the NICs with PCI address and device IDs. + lspci -nn | grep Eth + + For example suppose your output was as follows:: + + 82:00.0 Ethernet [0200]: Intel XL710 for 40GbE QSFP+ [8086:1583] + 82:00.1 Ethernet [0200]: Intel XL710 for 40GbE QSFP+ [8086:1583] + 85:00.0 Ethernet [0200]: Intel XL710 for 40GbE QSFP+ [8086:1583] + 85:00.1 Ethernet [0200]: Intel XL710 for 40GbE QSFP+ [8086:1583] + + Check the PCI device related numa node id: + + .. code-block:: console + + cat /sys/bus/pci/devices/0000\:xx\:00.x/numa_node + + Usually ``0x:00.x`` is on socket 0 and ``8x:00.x`` is on socket 1. + **Note**: To get the best performance, ensure that the core and NICs are in the same socket. + In the example above ``85:00.0`` is on socket 1 and should be used by cores on socket 1 for the best performance. + +4.

For example, to reserve 1024 pages of 2 MB, use:: + + hugepages=1024 + +For other hugepage sizes, for example 1G pages, the size must be specified explicitly and +can also be optionally set as the default hugepage size for the system. +For example, to reserve 4G of hugepage memory in the form of four 1G pages, the following options should be passed to the kernel:: + + default_hugepagesz=1G hugepagesz=1G hugepages=4 + +.. note:: + + The hugepage sizes that a CPU supports can be determined from the CPU flags on Intel architecture. + If pse exists, 2M hugepages are supported; if pdpe1gb exists, 1G hugepages are supported. + On IBM Power architecture, the supported hugepage sizes are 16MB and 16GB. + +.. note:: + + For 64-bit applications, it is recommended to use 1 GB hugepages if the platform supports them. + +In the case of a dual-socket NUMA system, +the number of hugepages reserved at boot time is generally divided equally between the two sockets +(on the assumption that sufficient memory is present on both sockets). + +See the Documentation/kernel-parameters.txt file in your Linux source tree for further details of these and other kernel options. + +**Alternative:** + +For 2 MB pages, there is also the option of allocating hugepages after the system has booted. +This is done by echoing the number of hugepages required to a nr_hugepages file in the ``/sys/devices/`` directory. +For a single-node system, the command to use is as follows (assuming that 1024 pages are required):: + + echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages + +On a NUMA machine, pages should be allocated explicitly on separate nodes:: + + echo 1024 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages + echo 1024 > /sys/devices/system/node/node1/hugepages/hugepages-2048kB/nr_hugepages + +.. note:: + + For 1G pages, it is not possible to reserve the hugepage memory after the system has booted. + + On IBM POWER system, the nr_overcommit_hugepages should be set to the same value as nr_hugepages. + For example, if the required page number is 128, the following commands are used:: + + echo 128 > /sys/kernel/mm/hugepages/hugepages-16384kB/nr_hugepages + echo 128 > /sys/kernel/mm/hugepages/hugepages-16384kB/nr_overcommit_hugepages + +Using Hugepages with the DPDK +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Once the hugepage memory is reserved, to make the memory available for DPDK use, perform the following steps:: + + mkdir /mnt/huge + mount -t hugetlbfs nodev /mnt/huge + +The mount point can be made permanent across reboots, by adding the following line to the ``/etc/fstab`` file:: + + nodev /mnt/huge hugetlbfs defaults 0 0 + +For 1GB pages, the page size must be specified as a mount option:: + + nodev /mnt/huge_1GB hugetlbfs pagesize=1GB 0 0 diff --git a/dpdk/doc/guides/mempool/index.rst b/dpdk/doc/guides/mempool/index.rst new file mode 100644 index 0000000..2ccf916 --- /dev/null +++ b/dpdk/doc/guides/mempool/index.rst @@ -0,0 +1,14 @@ +..

The Arkville RTL +component provides a single PCIe Physical Function (PF) supporting +some number of RX/Ingress and TX/Egress Queues. The ARK PMD controls +the Arkville core through a dedicated opaque Core BAR (CBAR). +To allow users full freedom for their own FPGA application IP, +an independent FPGA Application BAR (ABAR) is provided. + +One popular way to imagine Arkville's FPGA hardware aspect is as the +FPGA PCIe-facing side of a so-called Smart NIC. The Arkville core does +not contain any MACs, and is link-speed independent, as well as +agnostic to the number of physical ports the application chooses to +use. The ARK driver exposes the familiar PMD interface to allow packet +movement to and from mbufs across multiple queues. + +However FPGA RTL applications could contain a universe of added +functionality that an Arkville RTL core does not provide or can +not anticipate. To allow for this expectation of user-defined +innovation, the ARK PMD provides a dynamic mechanism of adding +capabilities without having to modify the ARK PMD. + +The ARK PMD is intended to support all instances of the Arkville +RTL Core, regardless of configuration, FPGA vendor, or target +board. While specific capabilities such as number of physical +hardware queue-pairs are negotiated; the driver is designed to +remain constant over a broad and extendable feature set. + +Intentionally, Arkville by itself DOES NOT provide common NIC +capabilities such as offload or receive-side scaling (RSS). +These capabilities would be viewed as a gate-level "tax" on +Green-box FPGA applications that do not require such function. +Instead, they can be added as needed with essentially no +overhead to the FPGA Application. + +The ARK PMD also supports optional user extensions, through dynamic linking. +The ARK PMD user extensions are a feature of Arkville’s DPDK +net/ark poll mode driver, allowing users to add their +own code to extend the net/ark functionality without +having to make source code changes to the driver. One motivation for +this capability is that while DPDK provides a rich set of functions +to interact with NIC-like capabilities (e.g. MAC addresses and statistics), +the Arkville RTL IP does not include a MAC. Users can supply their +own MAC or custom FPGA applications, which may require control from +the PMD. The user extension is the means providing the control +between the user's FPGA application and the existing DPDK features via +the PMD. + +Device Parameters +------------------- + +The ARK PMD supports device parameters that are used for packet +routing and for internal packet generation and packet checking. This +section describes the supported parameters. These features are +primarily used for diagnostics, testing, and performance verification +under the guidance of an Arkville specialist. The nominal use of +Arkville does not require any configuration using these parameters. + +"Pkt_dir" + +The Packet Director controls connectivity between Arkville's internal +hardware components.

The Wind River Systems virtualization platform +currently uses QEMU/KVM as its hypervisor and as such provides support for all +of the QEMU supported virtual and/or emulated devices (e.g., virtio, e1000, +etc.). The platform offers the virtio device type as the default device when +launching a virtual machine or creating a virtual machine port.

DPRC commands can be used to enumerate the contents +of the DPRC, discover the hardware objects present (including mappable +regions and interrupts). + +.. code-block:: console + + DPRC.1 (bus) + | + +--+--------+-------+-------+-------+ + | | | | | + DPMCP.1 DPIO.1 DPBP.1 DPNI.1 DPMAC.1 + DPMCP.2 DPIO.2 + DPMCP.3 + +Hardware objects can be created and destroyed dynamically, providing +the ability to hot plug/unplug objects in and out of the DPRC. + +A DPRC has a mappable MMIO region (an MC portal) that can be used +to send MC commands. It has an interrupt for status events (like +hotplug). + +All objects in a container share the same hardware "isolation context". +This means that with respect to an IOMMU the isolation granularity +is at the DPRC (container) level, not at the individual object +level. + +DPRCs can be defined statically and populated with objects +via a config file passed to the MC when firmware starts +it. There is also a Linux user space tool called "restool" +that can be used to create/destroy containers and objects +dynamically. + +DPAA2 Objects for an Ethernet Network Interface +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +A typical Ethernet NIC is monolithic-- the NIC device contains TX/RX +queuing mechanisms, configuration mechanisms, buffer management, +physical ports, and interrupts. DPAA2 uses a more granular approach +utilizing multiple hardware objects. Each object provides specialized +functions. Groups of these objects are used by software to provide +Ethernet network interface functionality. This approach provides +efficient use of finite hardware resources, flexibility, and +performance advantages. + +The diagram below shows the objects needed for a simple +network interface configuration on a system with 2 CPUs. + +.. code-block:: console + + +---+---+ +---+---+ + CPU0 CPU1 + +---+---+ +---+---+ + | | + +---+---+ +---+---+ + DPIO DPIO + +---+---+ +---+---+ + \ / + \ / + \ / + +---+---+ + DPNI --- DPBP,DPMCP + +---+---+ + | + | + +---+---+ + DPMAC + +---+---+ + | + port/PHY + +Below the objects are described. For each object a brief description +is provided along with a summary of the kinds of operations the object +supports and a summary of key resources of the object (MMIO regions +and IRQs). + +DPMAC (Datapath Ethernet MAC): represents an Ethernet MAC, a +hardware device that connects to an Ethernet PHY and allows +physical transmission and reception of Ethernet frames. + +- MMIO regions: none +- IRQs: DPNI link change +- commands: set link up/down, link config, get stats, IRQ config, enable, reset + +DPNI (Datapath Network Interface): contains TX/RX queues, +network interface configuration, and RX buffer pool configuration +mechanisms.

The DPAA2 +architecture separates the mechanism to access queues (the DPIO object) +from the queues themselves. The DPIO provides an MMIO interface to +enqueue/dequeue packets. To enqueue something a descriptor is written +to the DPIO MMIO region, which includes the target queue number. +There will typically be one DPIO assigned to each CPU. This allows all +CPUs to simultaneously perform enqueue/dequeued operations.

At the hardware level message interrupts +generated by devices will normally have 3 components-- +1) a non-spoofable 'device-id' expressed on the hardware +bus, 2) an address, 3) a data value. + +In the case of DPAA2 devices/objects, all objects in the +same container/DPRC share the same 'device-id'. +For ARM-based SoC this is the same as the stream ID. + + +DPAA2 DPDK - Poll Mode Driver Overview +-------------------------------------- + +This section provides an overview of the drivers for +DPAA2-- 1) the bus driver and associated "DPAA2 infrastructure" +drivers and 2) functional object drivers (such as Ethernet). + +As described previously, a DPRC is a container that holds the other +types of DPAA2 objects.

VIC Ethernet +NICs. These adapters are also referred to as vNICs below. If you are running +or would like to run DPDK software applications on Cisco UCS servers using +Cisco VIC adapters the following documentation is relevant. + +How to obtain ENIC PMD integrated DPDK +-------------------------------------- + +ENIC PMD support is integrated into the DPDK suite. dpdk-.tar.gz +should be downloaded from http://dpdk.org + + +Configuration information +------------------------- + +- **DPDK Configuration Parameters** + + The following configuration options are available for the ENIC PMD: + + - **CONFIG_RTE_LIBRTE_ENIC_PMD** (default y): Enables or disables inclusion + of the ENIC PMD driver in the DPDK compilation. + +- **vNIC Configuration Parameters** + + - **Number of Queues** + + The maximum number of receive queues (RQs), work queues (WQs) and + completion queues (CQs) are configurable on a per vNIC basis + through the Cisco UCS Manager (CIMC or UCSM). + + These values should be configured as follows: + + - The number of WQs should be greater or equal to the value of the + expected nb_tx_q parameter in the call to + rte_eth_dev_configure() + + - The number of RQs configured in the vNIC should be greater or + equal to *twice* the value of the expected nb_rx_q parameter in + the call to rte_eth_dev_configure(). With the addition of Rx + scatter, a pair of RQs on the vnic is needed for each receive + queue used by DPDK, even if Rx scatter is not being used. + Having a vNIC with only 1 RQ is not a valid configuration, and + will fail with an error message. + + - The number of CQs should set so that there is one CQ for each + WQ, and one CQ for each pair of RQs. + + For example: If the application requires 3 Rx queues, and 3 Tx + queues, the vNIC should be configured to have at least 3 WQs, 6 + RQs (3 pairs), and 6 CQs (3 for use by WQs + 3 for use by the 3 + pairs of RQs). + + - **Size of Queues** + + Likewise, the number of receive and transmit descriptors are configurable on + a per-vNIC basis via the UCS Manager and should be greater than or equal to + the nb_rx_desc and nb_tx_desc parameters expected to be used in the calls + to rte_eth_rx_queue_setup() and rte_eth_tx_queue_setup() respectively. + An application requesting more than the set size will be limited to that + size. + + Unless there is a lack of resources due to creating many vNICs, it + is recommended that the WQ and RQ sizes be set to the maximum. This + gives the application the greatest amount of flexibility in its + queue configuration. + + - *Note*: Since the introduction of Rx scatter, for performance + reasons, this PMD uses two RQs on the vNIC per receive queue in + DPDK. One RQ holds descriptors for the start of a packet, and the + second RQ holds the descriptors for the rest of the fragments of + a packet. This means that the nb_rx_desc parameter to + rte_eth_rx_queue_setup() can be a greater than 4096. The exact + amount will depend on the size of the mbufs being used for + receives, and the MTU size. + + For example: If the mbuf size is 2048, and the MTU is 9000, then + receiving a full size packet will take 5 descriptors, 1 from the + start-of-packet queue, and 4 from the second queue. Assuming + that the RQ size was set to the maximum of 4096, then the + application can specify up to 1024 + 4096 as the nb_rx_desc + parameter to rte_eth_rx_queue_setup(). + + - **Interrupts** + + Only one interrupt per vNIC interface should be configured in the UCS + manager regardless of the number receive/transmit queues. The ENIC PMD + uses this interrupt to get information about link status and errors + in the fast path. + +.. _enic-flow-director: + +Flow director support +--------------------- + +Advanced filtering support was added to 1300 series VIC firmware starting +with version 2.0.13 for C-series UCS servers and version 3.1.2 for UCSM +managed blade servers. In order to enable advanced filtering the 'Advanced +filter' radio button should be enabled via CIMC or UCSM followed by a reboot +of the server. + +With advanced filters, perfect matching of all fields of IPv4, IPv6 headers +as well as TCP, UDP and SCTP L4 headers is available through flow director. +Masking of these fields for partial match is also supported. + +Without advanced filter support, the flow director is limited to IPv4 +perfect filtering of the 5-tuple with no masking of fields supported. + +SR-IOV mode utilization +----------------------- + +UCS blade servers configured with dynamic vNIC connection policies in UCS +manager are capable of supporting assigned devices on virtual machines (VMs) +through a KVM hypervisor. Assigned devices, also known as 'passthrough' +devices, are SR-IOV virtual functions (VFs) on the host which are exposed +to VM instances. + +The Cisco Virtual Machine Fabric Extender (VM-FEX) gives the VM a dedicated +interface on the Fabric Interconnect (FI). Layer 2 switching is done at +the FI. This may eliminate the requirement for software switching on the +host to route intra-host VM traffic. + +Please refer to `Creating a Dynamic vNIC Connection Policy +`_ +for information on configuring SR-IOV adapter policies using UCS manager. + +Once the policies are in place and the host OS is rebooted, VFs should be +visible on the host, E.g.: + +.. code-block:: console + + # lspci | grep Cisco | grep Ethernet + 0d:00.0 Ethernet controller: Cisco Systems Inc VIC Ethernet NIC (rev a2) + 0d:00.1 Ethernet controller: Cisco Systems Inc VIC SR-IOV VF (rev a2) + 0d:00.2 Ethernet controller: Cisco Systems Inc VIC SR-IOV VF (rev a2) + 0d:00.3 Ethernet controller: Cisco Systems Inc VIC SR-IOV VF (rev a2) + 0d:00.4 Ethernet controller: Cisco Systems Inc VIC SR-IOV VF (rev a2) + 0d:00.5 Ethernet controller: Cisco Systems Inc VIC SR-IOV VF (rev a2) + 0d:00.6 Ethernet controller: Cisco Systems Inc VIC SR-IOV VF (rev a2) + 0d:00.7 Ethernet controller: Cisco Systems Inc VIC SR-IOV VF (rev a2) + +Enable Intel IOMMU on the host and install KVM and libvirt. A VM instance should +be created with an assigned device. When using libvirt, this configuration can +be done within the domain (i.e. VM) config file. For example this entry maps +host VF 0d:00:01 into the VM. + +.. code-block:: console + + + + +
+ + +Alternatively, the configuration can be done in a separate file using the +``network`` keyword. These methods are described in the libvirt documentation for +`Network XML format `_. + +When the VM instance is started, the ENIC KVM driver will bind the host VF to +vfio, complete provisioning on the FI and bring up the link. + +.. note:: + + It is not possible to use a VF directly from the host because it is not + fully provisioned until the hypervisor brings up the VM that it is assigned + to. + +In the VM instance, the VF will now be visible. E.g., here the VF 00:04.0 is +seen on the VM instance and should be available for binding to a DPDK. + +.. code-block:: console + + # lspci | grep Ether + 00:04.0 Ethernet controller: Cisco Systems Inc VIC SR-IOV VF (rev a2) + +Follow the normal DPDK install procedure, binding the VF to either ``igb_uio`` +or ``vfio`` in non-IOMMU mode. + +Please see :ref:`Limitations ` for limitations in +the use of SR-IOV. + +.. _enic-genic-flow-api: + +Generic Flow API support +------------------------ + +Generic Flow API is supported. The baseline support is: + +- **1200 series VICs** + + 5-tuple exact flow support for 1200 series adapters.

'last' is not supported + - In total, up to 64 bytes of mask is allowed across all headers + +More features may be added in future firmware and new versions of the VIC. +Please refer to the release notes. + +.. _enic_limitations: + +Limitations +----------- + +- **VLAN 0 Priority Tagging** + + If a vNIC is configured in TRUNK mode by the UCS manager, the adapter will + priority tag egress packets according to 802.1Q if they were not already + VLAN tagged by software. If the adapter is connected to a properly configured + switch, there will be no unexpected behavior. + + In test setups where an Ethernet port of a Cisco adapter in TRUNK mode is + connected point-to-point to another adapter port or connected though a router + instead of a switch, all ingress packets will be VLAN tagged. Programs such + as l3fwd which do not account for VLAN tags in packets will misbehave. The + solution is to enable VLAN stripping on ingress. The following code fragment is + an example of how to accomplish this: + +.. code-block:: console + + vlan_offload = rte_eth_dev_get_vlan_offload(port); + vlan_offload |= ETH_VLAN_STRIP_OFFLOAD; + rte_eth_dev_set_vlan_offload(port, vlan_offload); + +- Limited flow director support on 1200 series and 1300 series Cisco VIC + adapters with old firmware. Please see :ref:`enic-flow-director`. + +- Flow director features are not supported on generation 1 Cisco VIC adapters + (M81KR and P81E) + +- **SR-IOV** + + - KVM hypervisor support only. VMware has not been tested. + - Requires VM-FEX, and so is only available on UCS managed servers connected + to Fabric Interconnects. It is not on standalone C-Series servers. + - VF devices are not usable directly from the host. They can only be used + as assigned devices on VM instances. + - Currently, unbind of the ENIC kernel mode driver 'enic.ko' on the VM + instance may hang. As a workaround, enic.ko should be blacklisted or removed + from the boot process. + - pci_generic cannot be used as the uio module in the VM. igb_uio or + vfio in non-IOMMU mode can be used. + - The number of RQs in UCSM dynamic vNIC configurations must be at least 2. + - The number of SR-IOV devices is limited to 256. Components on target system + might limit this number to fewer than 256. + +- **Flow API** + + - The number of filters that can be specified with the Generic Flow API is + dependent on how many header fields are being masked. Use 'flow create' in + a loop to determine how many filters your VIC will support (not more than + 1000 for 1300 series VICs). Filters are checked for matching in the order they + were added. Since there currently is no grouping or priority support, + 'catch-all' filters should be added last. + +How to build the suite +---------------------- + +The build instructions for the DPDK suite should be followed. By default +the ENIC PMD library will be built into the DPDK library. + +Refer to the document :ref:`compiling and testing a PMD for a NIC +` for details. + +For configuring and using UIO and VFIO frameworks, please refer to the +documentation that comes with DPDK suite. + +Supported Cisco VIC adapters +---------------------------- + +ENIC PMD supports all recent generations of Cisco VIC adapters including: + +- VIC 1280 +- VIC 1240 +- VIC 1225 +- VIC 1285 +- VIC 1225T +- VIC 1227 +- VIC 1227T +- VIC 1380 +- VIC 1340 +- VIC 1385 +- VIC 1387 + +Supported Operating Systems +--------------------------- + +Any Linux distribution fulfilling the conditions described in Dependencies +section of DPDK documentation. + +Supported features +------------------ + +- Unicast, multicast and broadcast transmission and reception +- Receive queue polling +- Port Hardware Statistics +- Hardware VLAN acceleration +- IP checksum offload +- Receive side VLAN stripping +- Multiple receive and transmit queues +- Flow Director ADD, UPDATE, DELETE, STATS operation support IPv4 and IPv6 +- Promiscuous mode +- Setting RX VLAN (supported via UCSM/CIMC only) +- VLAN filtering (supported via UCSM/CIMC only) +- Execution of application by unprivileged system users +- IPV4, IPV6 and TCP RSS hashing +- Scattered Rx +- MTU update +- SR-IOV on UCS managed servers connected to Fabric Interconnects +- Flow API + +Known bugs and unsupported features in this release +--------------------------------------------------- + +- Signature or flex byte based flow direction +- Drop feature of flow direction +- VLAN based flow direction +- Non-IPV4 flow direction +- Setting of extended VLAN +- UDP RSS hashing +- MTU update only works if Scattered Rx mode is disabled + +Prerequisites +------------- + +- Prepare the system as recommended by DPDK suite.

You can enable it or disable it manually + by setting the ``CONFIG_RTE_LIBRTE_PMD_FAILSAFE`` configuration option. + +Features +-------- + +The Fail-safe PMD only supports a limited set of features. If you plan to use a +device underneath the Fail-safe PMD with a specific feature, this feature must +be supported by the Fail-safe PMD to avoid throwing any error. + +A notable exception is the device removal feature. The fail-safe PMD being a +virtual device, it cannot currently be removed in the sense of a specific bus +hotplug, like for PCI for example. It will however enable this feature for its +sub-device automatically, detecting those that are capable and register the +relevant callback for such event. + +Check the feature matrix for the complete set of supported features. + +Compilation option +------------------ + +This option can be modified in the ``$RTE_TARGET/build/.config`` file. + +- ``CONFIG_RTE_LIBRTE_PMD_FAILSAFE`` (default **y**) + + Toggle compiling librte_pmd_failsafe. + +Using the Fail-safe PMD from the EAL command line +------------------------------------------------- + +The Fail-safe PMD can be used like most other DPDK virtual devices, by passing a +``--vdev`` parameter to the EAL when starting the application. The device name +must start with the *net_failsafe* prefix, followed by numbers or letters. This +name must be unique for each device. Each fail-safe instance must have at least one +sub-device, up to ``RTE_MAX_ETHPORTS-1``. + +A sub-device can be any legal DPDK device, including possibly another fail-safe +instance. + +Fail-safe command line parameters +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +- **dev()** parameter + + This parameter allows the user to define a sub-device. The ```` part of + this parameter must be a valid device definition. It could be the argument + provided to any ``-w`` device specification or the argument that would be + given to a ``--vdev`` parameter (including a fail-safe). + Enclosing the device definition within parenthesis here allows using + additional sub-device parameters if need be. They will be passed on to the + sub-device. + +.. note:: + + In case of whitelist sub-device probed by EAL, fail-safe PMD will take the device + as is, which means that EAL device options are taken in this case. + When trying to use a PCI device automatically probed in blacklist mode, + the syntax for the fail-safe must be with the full PCI id: + Domain:Bus:Device.Function. See the usage example section. + +- **exec()** parameter + + This parameter allows the user to provide a command to the fail-safe PMD to + execute and define a sub-device. + It is done within a regular shell context. + The first line of its output is read by the fail-safe PMD and otherwise + interpreted as if passed by the regular **dev** parameter. + Any other line is discarded. + If the command fail or output an incorrect string, the sub-device is not + initialized. + All commas within the ``shell command`` are replaced by spaces before + executing the command. This helps using scripts to specify devices. + +- **fd()** parameter + + This parameter reads a device definition from an arbitrary file descriptor + number in ```` format as described above. + + The file descriptor is read in non-blocking mode and is never closed in + order to take only the last line into account (unlike ``exec()``) at every + probe attempt. + +- **mac** parameter [MAC address] + + This parameter allows the user to set a default MAC address to the fail-safe + and all of its sub-devices. + If no default mac address is provided, the fail-safe PMD will read the MAC + address of the first of its sub-device to be successfully probed and use it as + its default MAC address, trying to set it to all of its other sub-devices. + If no sub-device was successfully probed at initialization, then a random MAC + address is generated, that will be subsequently applied to all sub-device once + they are probed. + +- **hotplug_poll** parameter [UINT64] (default **2000**) + + This parameter allows the user to configure the amount of time in milliseconds + between two slave upkeep round. + +Usage example +~~~~~~~~~~~~~ + +This section shows some example of using **testpmd** with a fail-safe PMD. + +#. To build a PMD and configure DPDK, refer to the document + :ref:`compiling and testing a PMD for a NIC `. + +#. Start testpmd. The slave device should be blacklisted from normal EAL + operations to avoid probing it twice when in PCI blacklist mode. + + .. code-block:: console + + $RTE_TARGET/build/app/testpmd -c 0xff -n 4 \ + --vdev 'net_failsafe0,mac=de:ad:be:ef:01:02,dev(84:00.0),dev(net_ring0)' \ + -b 84:00.0 -b 00:04.0 -- -i + + If the slave device being used is not blacklisted, it will be probed by the + EAL first. When the fail-safe then tries to initialize it the probe operation + fails. + + Note that PCI blacklist mode is the default PCI operating mode. + +#. Alternatively, it can be used alongside any other device in whitelist mode. + + .. code-block:: console + + $RTE_TARGET/build/app/testpmd -c 0xff -n 4 \ + --vdev 'net_failsafe0,mac=de:ad:be:ef:01:02,dev(84:00.0),dev(net_ring0)' \ + -w 81:00.0 -- -i + +#. Start testpmd using a flexible device definition + + .. code-block:: console + + $RTE_TARGET/build/app/testpmd -c 0xff -n 4 --no-pci \ + --vdev='net_failsafe0,exec(echo 84:00.0)' -- -i + +#. Start testpmd, automatically probing the device 84:00.0 and using it with + the fail-safe. + + .. code-block:: console + + $RTE_TARGET/build/app/testpmd -c 0xff -n 4 \ + --vdev 'net_failsafe0,dev(0000:84:00.0),dev(net_ring0)' -- -i + + +Using the Fail-safe PMD from an application +------------------------------------------- + +This driver strives to be as seamless as possible to existing applications, in +order to propose the hotplug functionality in the easiest way possible. + +Care must be taken, however, to respect the **ether** API concerning device +access, and in particular, using the ``RTE_ETH_FOREACH_DEV`` macro to iterate +over ethernet devices, instead of directly accessing them or by writing one's +own device iterator. + +Plug-in feature +--------------- + +A sub-device can be defined without existing on the system when the fail-safe +PMD is initialized. Upon probing this device, the fail-safe PMD will detect its +absence and postpone its use. It will then register for a periodic check on any +missing sub-device. + +During this time, the fail-safe PMD can be used normally, configured and told to +emit and receive packets. It will store any applied configuration, and try to +apply it upon the probing of its missing sub-device. After this configuration +pass, the new sub-device will be synchronized with other sub-devices, i.e. be +started if the fail-safe PMD has been started by the user before. + +Plug-out feature +---------------- + +A sub-device supporting the device removal event can be removed from its bus at +any time. The fail-safe PMD will register a callback for such event and react +accordingly. It will try to safely stop, close and uninit the sub-device having +emitted this event, allowing it to free its eventual resources. + +Fail-safe glossary +------------------ + +Fallback device : Secondary device + The fail-safe will fail-over onto this device when the preferred device is + absent. + +Preferred device : Primary device + The first declared sub-device in the fail-safe parameters. + When this device is plugged, it is always used as emitting device. + It is the main sub-device and is used as target for configuration + operations if there is any ambiguity. + +Upkeep round + Periodical process when slaves are serviced. Each devices having a state + different to that of the fail-safe device itself, is synchronized with it. + Additionally, each slave having the remove flag set are cleaned-up. + +Slave + In the context of the fail-safe PMD, synonymous to sub-device. + +Sub-device + A device being utilized by the fail-safe PMD. + This is another PMD running underneath the fail-safe PMD. + Any sub-device can disappear at any time.

SPDX-License-Identifier: BSD-3-Clause + Copyright(c) 2015-2016 Intel Corporation. + +FM10K Poll Mode Driver +====================== + +The FM10K poll mode driver library provides support for the Intel FM10000 +(FM10K) family of 40GbE/100GbE adapters. + +FTAG Based Forwarding of FM10K +------------------------------ + +FTAG Based Forwarding is a unique feature of FM10K. The FM10K family of NICs +support the addition of a Fabric Tag (FTAG) to carry special information. +The FTAG is placed at the beginning of the frame, it contains information +such as where the packet comes from and goes, and the vlan tag. In FTAG based +forwarding mode, the switch logic forwards packets according to glort (global +resource tag) information, rather than the mac and vlan table. Currently this +feature works only on PF. + +To enable this feature, the user should pass a devargs parameter to the eal +like "-w 84:00.0,enable_ftag=1", and the application should make sure an +appropriate FTAG is inserted for every frame on TX side. + +Vector PMD for FM10K +-------------------- + +Vector PMD (vPMD) uses Intel® SIMD instructions to optimize packet I/O. +It improves load/store bandwidth efficiency of L1 data cache by using a wider +SSE/AVX ''register (1)''. +The wider register gives space to hold multiple packet buffers so as to save +on the number of instructions when bulk processing packets. + +There is no change to the PMD API. The RX/TX handlers are the only two entries for +vPMD packet I/O. They are transparently registered at runtime RX/TX execution +if all required conditions are met. + +1. To date, only an SSE version of FM10K vPMD is available. + To ensure that vPMD is in the binary code, set + ``CONFIG_RTE_LIBRTE_FM10K_INC_VECTOR=y`` in the configure file. + +Some constraints apply as pre-conditions for specific optimizations on bulk +packet transfers. The following sections explain RX and TX constraints in the +vPMD. + + +RX Constraints +~~~~~~~~~~~~~~ + + +Prerequisites and Pre-conditions +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +For Vector RX it is assumed that the number of descriptor rings will be a power +of 2. With this pre-condition, the ring pointer can easily scroll back to the +head after hitting the tail without a conditional check. In addition Vector RX +can use this assumption to do a bit mask using ``ring_size - 1``. + + +Features not Supported by Vector RX PMD +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Some features are not supported when trying to increase the throughput in +vPMD. They are: + +* IEEE1588 + +* Flow director + +* Header split + +* RX checksum offload + +Other features are supported using optional MACRO configuration. They include: + +* HW VLAN strip + +* L3/L4 packet type + +To enable via ``RX_OLFLAGS`` use ``RTE_LIBRTE_FM10K_RX_OLFLAGS_ENABLE=y``. + +To guarantee the constraint, the following configuration flags in ``dev_conf.rxmode`` +will be checked: + +* ``hw_vlan_extend`` + +* ``hw_ip_checksum`` + +* ``header_split`` + +* ``fdir_conf->mode`` + + +RX Burst Size +^^^^^^^^^^^^^ + +As vPMD is focused on high throughput, it processes 4 packets at a time. So it assumes +that the RX burst should be greater than 4 packets per burst. It returns zero if using +``nb_pkt`` < 4 in the receive handler. If ``nb_pkt`` is not a multiple of 4, a +floor alignment will be applied. + + +TX Constraint +~~~~~~~~~~~~~ + +Features not Supported by TX Vector PMD +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +TX vPMD only works when ``txq_flags`` is set to ``FM10K_SIMPLE_TX_FLAG``. +This means that it does not support TX multi-segment, VLAN offload or TX csum +offload. The following MACROs are used for these three features: + +* ``ETH_TXQ_FLAGS_NOMULTSEGS`` + +* ``ETH_TXQ_FLAGS_NOVLANOFFL`` + +* ``ETH_TXQ_FLAGS_NOXSUMSCTP`` + +* ``ETH_TXQ_FLAGS_NOXSUMUDP`` + +* ``ETH_TXQ_FLAGS_NOXSUMTCP`` + +Limitations +----------- + + +Switch manager +~~~~~~~~~~~~~~ + +The Intel FM10000 family of NICs integrate a hardware switch and multiple host +interfaces. The FM10000 PMD driver only manages host interfaces. For the +switch component another switch driver has to be loaded prior to to the +FM10000 PMD driver. The switch driver can be acquired from Intel support. +Only Testpoint is validated with DPDK, the latest version that has been +validated with DPDK is 4.1.6. + +Support for Switch Restart +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +For FM10000 multi host based design a DPDK app running in the VM or host needs +to be aware of the switch's state since it may undergo a quit-restart. When +the switch goes down the DPDK app will receive a LSC event indicating link +status down, and the app should stop the worker threads that are polling on +the Rx/Tx queues. When switch comes up, a LSC event indicating ``LINK_UP`` is +sent to the app, which can then restart the FM10000 port to resume network +processing. + +CRC striping +~~~~~~~~~~~~ + +The FM10000 family of NICs strip the CRC for every packets coming into the +host interface. So, CRC will be stripped even when the +``rxmode.hw_strip_crc`` member is set to 0 in ``struct rte_eth_conf``. + + +Maximum packet length +~~~~~~~~~~~~~~~~~~~~~ + +The FM10000 family of NICS support a maximum of a 15K jumbo frame. The value +is fixed and cannot be changed. So, even when the ``rxmode.max_rx_pkt_len`` +member of ``struct rte_eth_conf`` is set to a value lower than 15364, frames +up to 15364 bytes can still reach the host interface. + +Statistic Polling Frequency +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The FM10000 NICs expose a set of statistics via the PCI BARs. These statistics +are read from the hardware registers when ``rte_eth_stats_get()`` or +``rte_eth_xstats_get()`` is called. The packet counting registers are 32 bits +while the byte counting registers are 48 bits. As a result, the statistics must +be polled regularly in order to ensure the consistency of the returned reads. + +Given the PCIe Gen3 x8, about 50Gbps of traffic can occur. With 64 byte packets +this gives almost 100 million packets/second, causing 32 bit integer overflow +after approx 40 seconds. To ensure these overflows are detected and accounted +for in the statistics, it is necessary to read statistic regularly. It is +suggested to read stats every 20 seconds, which will ensure the statistics +are accurate. + + +Interrupt mode +~~~~~~~~~~~~~~ + +The FM10000 family of NICS need one separate interrupt for mailbox. So only +drivers which support multiple interrupt vectors e.g. vfio-pci can work +for fm10k interrupt mode. diff --git a/dpdk/doc/guides/nics/i40e.rst b/dpdk/doc/guides/nics/i40e.rst new file mode 100644 index 0000000..e1b8083 --- /dev/null +++ b/dpdk/doc/guides/nics/i40e.rst @@ -0,0 +1,642 @@ +..

As such, this +feature provides security benefits. + +In addition, a Floating VEB overcomes a limitation of normal VEBs where they +cannot forward packets when the physical link is down. Floating VEBs don't need +to connect to the NIC port so they can still forward traffic from VF to VF +even when the physical link is down. + +Therefore, with this feature enabled VFs can be limited to communicating with +each other but not an outside network, and they can do so even when there is +no physical uplink on the associated NIC port. + +To enable this feature, the user should pass a ``devargs`` parameter to the +EAL, for example:: + + -w 84:00.0,enable_floating_veb=1 + +In this configuration the PMD will use the floating VEB feature for all the +VFs created by this PF device. + +Alternatively, the user can specify which VFs need to connect to this floating +VEB using the ``floating_veb_list`` argument:: + + -w 84:00.0,enable_floating_veb=1,floating_veb_list=1;3-4 + +In this example ``VF1``, ``VF3`` and ``VF4`` connect to the floating VEB, +while other VFs connect to the normal VEB. + +The current implementation only supports one floating VEB and one regular +VEB. VFs can connect to a floating VEB or a regular VEB according to the +configuration passed on the EAL command line. + +The floating VEB functionality requires a NIC firmware version of 5.0 +or greater. + +Dynamic Device Personalization (DDP) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The Intel® Ethernet Controller X*710 support a feature called "Dynamic Device +Personalization (DDP)", which is used to configure hardware by downloading +a profile to support protocols/filters which are not supported by default. +The DDP functionality requires a NIC firmware version of 6.0 or greater. + +Current implementation supports MPLSoUDP/MPLSoGRE/GTP-C/GTP-U/PPPoE/PPPoL2TP, +steering can be used with rte_flow API. + +Load a profile which supports MPLSoUDP/MPLSoGRE and store backup profile: + +.. code-block:: console + + testpmd> ddp add 0 ./mpls.pkgo,./backup.pkgo + +Delete a MPLS profile and restore backup profile: + +.. code-block:: console + + testpmd> ddp del 0 ./backup.pkgo + +Get loaded DDP package info list: + +.. code-block:: console + + testpmd> ddp get list 0 + +Display information about a MPLS profile: + +.. code-block:: console + + testpmd> ddp get info ./mpls.pkgo + +Input set configuration +~~~~~~~~~~~~~~~~~~~~~~~ +Input set for any PCTYPE can be configured with user defined configuration, +For example, to use only 48bit prefix for IPv6 src address for IPv6 TCP RSS: + +.. code-block:: console + + testpmd> port config 0 pctype 43 hash_inset clear all + testpmd> port config 0 pctype 43 hash_inset set field 13 + testpmd> port config 0 pctype 43 hash_inset set field 14 + testpmd> port config 0 pctype 43 hash_inset set field 15 + +Queue region configuration +~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The Ethernet Controller X710/XL710 supports a feature of queue regions +configuration for RSS in the PF, so that different traffic classes or +different packet classification types can be separated to different +queues in different queue regions. There is an API for configuration +of queue regions in RSS with a command line. It can parse the parameters +of the region index, queue number, queue start index, user priority, traffic +classes and so on. Depending on commands from the command line, it will call +i40e private APIs and start the process of setting or flushing the queue +region configuration. As this feature is specific for i40e only private +APIs are used. These new ``test_pmd`` commands are as shown below. For +details please refer to :doc:`../testpmd_app_ug/index`. + +.. code-block:: console + + testpmd> set port (port_id) queue-region region_id (value) \ + queue_start_index (value) queue_num (value) + testpmd> set port (port_id) queue-region region_id (value) flowtype (value) + testpmd> set port (port_id) queue-region UP (value) region_id (value) + testpmd> set port (port_id) queue-region flush (on|off) + testpmd> show port (port_id) queue-region + +Limitations or Known issues +--------------------------- + +MPLS packet classification on X710/XL710 +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +For firmware versions prior to 5.0, MPLS packets are not recognized by the NIC. +The L2 Payload flow type in flow director can be used to classify MPLS packet +by using a command in testpmd like: + + testpmd> flow_director_filter 0 mode IP add flow l2_payload ether \ + 0x8847 flexbytes () fwd pf queue fd_id + +With the NIC firmware version 5.0 or greater, some limited MPLS support +is added: Native MPLS (MPLS in Ethernet) skip is implemented, while no +new packet type, no classification or offload are possible. With this change, +L2 Payload flow type in flow director cannot be used to classify MPLS packet +as with previous firmware versions. Meanwhile, the Ethertype filter can be +used to classify MPLS packet by using a command in testpmd like: + + testpmd> ethertype_filter 0 add mac_ignr 00:00:00:00:00:00 ethertype \ + 0x8847 fwd queue + +16 Byte RX Descriptor setting on DPDK VF +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Currently the VF's RX descriptor mode is decided by PF. There's no PF-VF +interface for VF to request the RX descriptor mode, also no interface to notify +VF its own RX descriptor mode. +For all available versions of the i40e driver, these drivers don't support 16 +byte RX descriptor. If the Linux i40e kernel driver is used as host driver, +while DPDK i40e PMD is used as the VF driver, DPDK cannot choose 16 byte receive +descriptor. The reason is that the RX descriptor is already set to 32 byte by +the i40e kernel driver. That is to say, user should keep +``CONFIG_RTE_LIBRTE_I40E_16BYTE_RX_DESC=n`` in config file. +In the future, if the Linux i40e driver supports 16 byte RX descriptor, user +should make sure the DPDK VF uses the same RX descriptor mode, 16 byte or 32 +byte, as the PF driver. + +The same rule for DPDK PF + DPDK VF. The PF and VF should use the same RX +descriptor mode. Or the VF RX will not work. + +Receive packets with Ethertype 0x88A8 +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Due to the FW limitation, PF can receive packets with Ethertype 0x88A8 +only when floating VEB is disabled. + +Incorrect Rx statistics when packet is oversize +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +When a packet is over maximum frame size, the packet is dropped. +However the Rx statistics, when calling `rte_eth_stats_get` incorrectly +shows it as received. + +VF & TC max bandwidth setting +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The per VF max bandwidth and per TC max bandwidth cannot be enabled in parallel. +The dehavior is different when handling per VF and per TC max bandwidth setting. +When enabling per VF max bandwidth, SW will check if per TC max bandwidth is +enabled. If so, return failure. +When enabling per TC max bandwidth, SW will check if per VF max bandwidth +is enabled. If so, disable per VF max bandwidth and continue with per TC max +bandwidth setting. + +TC TX scheduling mode setting +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +There're 2 TX scheduling modes for TCs, round robin and strict priority mode. +If a TC is set to strict priority mode, it can consume unlimited bandwidth. +It means if APP has set the max bandwidth for that TC, it comes to no +effect. +It's suggested to set the strict priority mode for a TC that is latency +sensitive but no consuming much bandwidth. + +VF performance is impacted by PCI extended tag setting +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +To reach maximum NIC performance in the VF the PCI extended tag must be +enabled. The DPDK I40E PF driver will set this feature during initialization, +but the kernel PF driver does not. So when running traffic on a VF which is +managed by the kernel PF driver, a significant NIC performance downgrade has +been observed (for 64 byte packets, there is about 25% linerate downgrade for +a 25G device and about 35% for a 40G device). + +For kernel version >= 4.11, the kernel's PCI driver will enable the extended +tag if it detects that the device supports it. So by default, this is not an +issue. For kernels <= 4.11 or when the PCI extended tag is disabled it can be +enabled using the steps below. + +#. Get the current value of the PCI configure register:: + + setpci -s a8.w + +#. Set bit 8:: + + value = value | 0x100 + +#. Set the PCI configure register with new value:: + + setpci -s a8.w= + +Vlan strip of VF +~~~~~~~~~~~~~~~~ + +The VF vlan strip function is only supported in the i40e kernel driver >= 2.1.26. + +DCB function +~~~~~~~~~~~~ + +DCB works only when RSS is enabled. + +Global configuration warning +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +I40E PMD will set some global registers to enable some function or set some +configure. Then when using different ports of the same NIC with Linux kernel +and DPDK, the port with Linux kernel will be impacted by the port with DPDK. +For example, register I40E_GL_SWT_L2TAGCTRL is used to control L2 tag, i40e +PMD uses I40E_GL_SWT_L2TAGCTRL to set vlan TPID. If setting TPID in port A +with DPDK, then the configuration will also impact port B in the NIC with +kernel driver, which don't want to use the TPID. +So PMD reports warning to clarify what is changed by writing global register. + +High Performance of Small Packets on 40G NIC +-------------------------------------------- + +As there might be firmware fixes for performance enhancement in latest version +of firmware image, the firmware update might be needed for getting high performance. +Check with the local Intel's Network Division application engineers for firmware updates. +Users should consult the release notes specific to a DPDK release to identify +the validated firmware version for a NIC using the i40e driver. + +Use 16 Bytes RX Descriptor Size +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +As i40e PMD supports both 16 and 32 bytes RX descriptor sizes, and 16 bytes size can provide helps to high performance of small packets. +Configuration of ``CONFIG_RTE_LIBRTE_I40E_16BYTE_RX_DESC`` in config files can be changed to use 16 bytes size RX descriptors. + +High Performance and per Packet Latency Tradeoff +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Due to the hardware design, the interrupt signal inside NIC is needed for per +packet descriptor write-back. The minimum interval of interrupts could be set +at compile time by ``CONFIG_RTE_LIBRTE_I40E_ITR_INTERVAL`` in configuration files. +Though there is a default configuration, the interval could be tuned by the +users with that configuration item depends on what the user cares about more, +performance or per packet latency. + +Example of getting best performance with l3fwd example +------------------------------------------------------ + +The following is an example of running the DPDK ``l3fwd`` sample application to get high performance with an +Intel server platform and Intel XL710 NICs. + +The example scenario is to get best performance with two Intel XL710 40GbE ports. +See :numref:`figure_intel_perf_test_setup` for the performance test setup. + +.. _figure_intel_perf_test_setup: + +.. figure:: img/intel_perf_test_setup.* + + Performance Test Setup + + +1. Add two Intel XL710 NICs to the platform, and use one port per card to get best performance. + The reason for using two NICs is to overcome a PCIe Gen3's limitation since it cannot provide 80G bandwidth + for two 40G ports, but two different PCIe Gen3 x8 slot can. + Refer to the sample NICs output above, then we can select ``82:00.0`` and ``85:00.0`` as test ports:: + + 82:00.0 Ethernet [0200]: Intel XL710 for 40GbE QSFP+ [8086:1583] + 85:00.0 Ethernet [0200]: Intel XL710 for 40GbE QSFP+ [8086:1583] + +2. Connect the ports to the traffic generator. For high speed testing, it's best to use a hardware traffic generator. + +3. Check the PCI devices numa node (socket id) and get the cores number on the exact socket id. + In this case, ``82:00.0`` and ``85:00.0`` are both in socket 1, and the cores on socket 1 in the referenced platform + are 18-35 and 54-71. + Note: Don't use 2 logical cores on the same core (e.g core18 has 2 logical cores, core18 and core54), instead, use 2 logical + cores from different cores (e.g core18 and core19). + +4. Bind these two ports to igb_uio. + +5. As to XL710 40G port, we need at least two queue pairs to achieve best performance, then two queues per port + will be required, and each queue pair will need a dedicated CPU core for receiving/transmitting packets. + +6. The DPDK sample application ``l3fwd`` will be used for performance testing, with using two ports for bi-directional forwarding. + Compile the ``l3fwd sample`` with the default lpm mode. + +7. The command line of running l3fwd would be something like the following:: + + ./l3fwd -l 18-21 -n 4 -w 82:00.0 -w 85:00.0 \ + -- -p 0x3 --config '(0,0,18),(0,1,19),(1,0,20),(1,1,21)' + + This means that the application uses core 18 for port 0, queue pair 0 forwarding, core 19 for port 0, queue pair 1 forwarding, + core 20 for port 1, queue pair 0 forwarding, and core 21 for port 1, queue pair 1 forwarding. + +8. Configure the traffic at a traffic generator. + + * Start creating a stream on packet generator. + + * Set the Ethernet II type to 0x0800. diff --git a/dpdk/doc/guides/nics/igb.rst b/dpdk/doc/guides/nics/igb.rst new file mode 100644 index 0000000..0171622 --- /dev/null +++ b/dpdk/doc/guides/nics/igb.rst @@ -0,0 +1,38 @@ +..

We may hit problem in this +scenario kernel PF + DPDK VF. If user enables MDD in kernel PF, DPDK VF will +not work. Because kernel PF thinks the VF is malicious. But actually it's not. +The only reason is the VF doesn't act as MDD required. +There's significant performance impact to support MDD. DPDK should check if +the advanced context descriptor should be set and set it. And DPDK has to ask +the info about the header length from the upper layer, because parsing the +packet itself is not acceptable. So, it's too expensive to support MDD. +When using kernel PF + DPDK VF on x550, please make sure to use a kernel +PF driver that disables MDD or can disable MDD. + +Some kernel drivers already disable MDD by default while some kernels can use +the command ``insmod ixgbe.ko MDD=0,0`` to disable MDD. Each "0" in the +command refers to a port. For example, if there are 6 ixgbe ports, the command +should be changed to ``insmod ixgbe.ko MDD=0,0,0,0,0,0``. + + +Statistics +~~~~~~~~~~ + +The statistics of ixgbe hardware must be polled regularly in order for it to +remain consistent. Running a DPDK application without polling the statistics will +cause registers on hardware to count to the maximum value, and "stick" at +that value. + +In order to avoid statistic registers every reaching the maximum value, +read the statistics from the hardware using ``rte_eth_stats_get()`` or +``rte_eth_xstats_get()``. + +The maximum time between statistics polls that ensures consistent results can +be calculated as follows: + +.. code-block:: c + + max_read_interval = UINT_MAX / max_packets_per_second + max_read_interval = 4294967295 / 14880952 + max_read_interval = 288.6218096127183 (seconds) + max_read_interval = ~4 mins 48 sec. + +In order to ensure valid results, it is recommended to poll every 4 minutes. + +MTU setting +~~~~~~~~~~~ + +Although the user can set the MTU separately on PF and VF ports, the ixgbe NIC +only supports one global MTU per physical port. +So when the user sets different MTUs on PF and VF ports in one physical port, +the real MTU for all these PF and VF ports is the largest value set. +This behavior is based on the kernel driver behavior. + +VF MAC address setting +~~~~~~~~~~~~~~~~~~~~~~ + +On ixgbe, the concept of "pool" can be used for different things depending on +the mode. In VMDq mode, "pool" means a VMDq pool. In IOV mode, "pool" means a +VF. + +There is no RTE API to add a VF's MAC address from the PF.

Help is also provided by +the `Mellanox community `_. + +There is also a `section dedicated to this poll mode driver +`_. + +.. note:: + + Due to external dependencies, this driver is disabled by default. It must + be enabled manually by setting ``CONFIG_RTE_LIBRTE_MLX4_PMD=y`` and + recompiling DPDK. + +Implementation details +---------------------- + +Most Mellanox ConnectX-3 devices provide two ports but expose a single PCI +bus address, thus unlike most drivers, librte_pmd_mlx4 registers itself as a +PCI driver that allocates one Ethernet device per detected port. + +For this reason, one cannot white/blacklist a single port without also +white/blacklisting the others on the same device. + +Besides its dependency on libibverbs (that implies libmlx4 and associated +kernel support), librte_pmd_mlx4 relies heavily on system calls for control +operations such as querying/updating the MTU and flow control parameters. + +For security reasons and robustness, this driver only deals with virtual +memory addresses. The way resources allocations are handled by the kernel +combined with hardware specifications that allow it to handle virtual memory +addresses directly ensure that DPDK applications cannot access random +physical memory (or memory that does not belong to the current process). + +This capability allows the PMD to coexist with kernel network interfaces +which remain functional, although they stop receiving unicast packets as +long as they share the same MAC address. + +Compiling librte_pmd_mlx4 causes DPDK to be linked against libibverbs. + +Configuration +------------- + +Compilation options +~~~~~~~~~~~~~~~~~~~ + +These options can be modified in the ``.config`` file. + +- ``CONFIG_RTE_LIBRTE_MLX4_PMD`` (default **n**) + + Toggle compilation of librte_pmd_mlx4 itself. + +- ``CONFIG_RTE_LIBRTE_MLX4_DLOPEN_DEPS`` (default **n**) + + Build PMD with additional code to make it loadable without hard + dependencies on **libibverbs** nor **libmlx4**, which may not be installed + on the target system. + + In this mode, their presence is still required for it to run properly, + however their absence won't prevent a DPDK application from starting (with + ``CONFIG_RTE_BUILD_SHARED_LIB`` disabled) and they won't show up as + missing with ``ldd(1)``. + + It works by moving these dependencies to a purpose-built rdma-core "glue" + plug-in which must either be installed in a directory whose name is based + on ``CONFIG_RTE_EAL_PMD_PATH`` suffixed with ``-glue`` if set, or in a + standard location for the dynamic linker (e.g. ``/lib``) if left to the + default empty string (``""``). + + This option has no performance impact. + +- ``CONFIG_RTE_LIBRTE_MLX4_DEBUG`` (default **n**) + + Toggle debugging code and stricter compilation flags.

Verify the optimized steering mode is configured: + + .. code-block:: console + + cat /sys/module/mlx4_core/parameters/log_num_mgm_entry_size + +2. Use the CPU near local NUMA node to which the PCIe adapter is connected, + for better performance. For VMs, verify that the right CPU + and NUMA node are pinned according to the above. Run: + + .. code-block:: console + + lstopo-no-graphics + + to identify the NUMA node to which the PCIe adapter is connected. + +3. If more than one adapter is used, and root complex capabilities allow + to put both adapters on the same NUMA node without PCI bandwidth degradation, + it is recommended to locate both adapters on the same NUMA node. + This in order to forward packets from one to the other without + NUMA performance penalty. + +4. Disable pause frames: + + .. code-block:: console + + ethtool -A rx off tx off + +5. Verify IO non-posted prefetch is disabled by default. This can be checked + via the BIOS configuration. Please contact you server provider for more + information about the settings. + +.. note:: + + On some machines, depends on the machine integrator, it is beneficial + to set the PCI max read request parameter to 1K.

In addition, + Enhanced MPS supports hybrid mode - mixing inlined packets and pointers + in the same descriptor. + + This option cannot be used with certain offloads such as ``DEV_TX_OFFLOAD_TCP_TSO, + DEV_TX_OFFLOAD_VXLAN_TNL_TSO, DEV_TX_OFFLOAD_GRE_TNL_TSO, DEV_TX_OFFLOAD_VLAN_INSERT``. + When those offloads are requested the MPS send function will not be used. + + It is currently only supported on the ConnectX-4 Lx and ConnectX-5 + families of adapters. Enabled by default. + +- ``txq_mpw_hdr_dseg_en`` parameter [int] + + A nonzero value enables including two pointers in the first block of TX + descriptor. This can be used to lessen CPU load for memory copy. + + Effective only when Enhanced MPS is supported. Disabled by default. + +- ``txq_max_inline_len`` parameter [int] + + Maximum size of packet to be inlined. This limits the size of packet to + be inlined. If the size of a packet is larger than configured value, the + packet isn't inlined even though there's enough space remained in the + descriptor. Instead, the packet is included with pointer. + + Effective only when Enhanced MPS is supported. The default value is 256. + +- ``tx_vec_en`` parameter [int] + + A nonzero value enables Tx vector on ConnectX-5 only NIC if the number of + global Tx queues on the port is lesser than MLX5_VPMD_MIN_TXQS. + + This option cannot be used with certain offloads such as ``DEV_TX_OFFLOAD_TCP_TSO, + DEV_TX_OFFLOAD_VXLAN_TNL_TSO, DEV_TX_OFFLOAD_GRE_TNL_TSO, DEV_TX_OFFLOAD_VLAN_INSERT``. + When those offloads are requested the MPS send function will not be used. + + Enabled by default on ConnectX-5. + +- ``rx_vec_en`` parameter [int] + + A nonzero value enables Rx vector if the port is not configured in + multi-segment otherwise this parameter is ignored. + + Enabled by default. + +Prerequisites +------------- + +This driver relies on external libraries and kernel drivers for resources +allocations and initialization. The following dependencies are not part of +DPDK and must be installed separately: + +- **libibverbs** + + User space Verbs framework used by librte_pmd_mlx5. This library provides + a generic interface between the kernel and low-level user space drivers + such as libmlx5. + + It allows slow and privileged operations (context initialization, hardware + resources allocations) to be managed by the kernel and fast operations to + never leave user space. + +- **libmlx5** + + Low-level user space driver library for Mellanox ConnectX-4/ConnectX-5 + devices, it is automatically loaded by libibverbs. + + This library basically implements send/receive calls to the hardware + queues. + +- **Kernel modules** + + They provide the kernel-side Verbs API and low level device drivers that + manage actual hardware initialization and resources sharing with user + space processes. + + Unlike most other PMDs, these modules must remain loaded and bound to + their devices: + + - mlx5_core: hardware driver managing Mellanox ConnectX-4/ConnectX-5 + devices and related Ethernet kernel network devices. + - mlx5_ib: InifiniBand device driver. + - ib_uverbs: user space driver for Verbs (entry point for libibverbs). + +- **Firmware update** + + Mellanox OFED releases include firmware updates for ConnectX-4/ConnectX-5 + adapters. + + Because each release provides new features, these updates must be applied to + match the kernel modules and libraries they come with. + +.. note:: + + Both libraries are BSD and GPL licensed.

Support for older kernels can be obtained +on Github at +**https://github.com/Netronome/nfp-drv-kmods** along with the build +instructions. + +NFP PMD needs to be used along with UIO ``igb_uio`` or VFIO (``vfio-pci``) +Linux kernel driver. + +Building the software +--------------------- + +Netronome's PMD code is provided in the **drivers/net/nfp** directory. +Although NFP PMD has Netronome´s BSP dependencies, it is possible to +compile it along with other DPDK PMDs even if no BSP was installed previously. +Of course, a DPDK app will require such a BSP installed for using the +NFP PMD, along with a specific NFP firmware application. + +Default PMD configuration is at the **common_linuxapp configuration** file: + +- **CONFIG_RTE_LIBRTE_NFP_PMD=y** + +Once the DPDK is built all the DPDK apps and examples include support for +the NFP PMD. + + +Driver compilation and testing +------------------------------ + +Refer to the document :ref:`compiling and testing a PMD for a NIC ` +for details. + +Using the PF +------------ + +NFP PMD supports using the NFP PF as another DPDK port, but it does not +have any functionality for controlling VFs. In fact, it is not possible to use +the PMD with the VFs if the PF is being used by DPDK, that is, with the NFP PF +bound to ``igb_uio`` or ``vfio-pci`` kernel drivers. Future DPDK versions will +have a PMD able to work with the PF and VFs at the same time and with the PF +implementing VF management along with other PF-only functionalities/offloads. + +The PMD PF has extra work to do which will delay the DPDK app initialization. +This additional effort could be checking if a firmware is already available in +the device, uploading the firmware if necessary or configuring the Link state +properly when starting or stopping a PF port. Note that firmware upload is not +always necessary which is the main delay for NFP PF PMD initialization. + +Depending on the Netronome product installed in the system, firmware files +should be available under ``/lib/firmware/netronome``. DPDK PMD supporting the +PF requires a specific link, ``/lib/firmware/netronome/nic_dpdk_default.nffw``, +which should be created automatically with Netronome's Agilio products +installation. + +PF multiport support +-------------------- + +Some NFP cards support several physical ports with just one single PCI device. +The DPDK core is designed with a 1:1 relationship between PCI devices and DPDK +ports, so NFP PMD PF support requires handling the multiport case specifically. +During NFP PF initialization, the PMD will extract the information about the +number of PF ports from the firmware and will create as many DPDK ports as +needed. + +Because the unusual relationship between a single PCI device and several DPDK +ports, there are some limitations when using more than one PF DPDK port: there +is no support for RX interrupts and it is not possible either to use those PF +ports with the device hotplug functionality. + + +System configuration +-------------------- + +#. **Enable SR-IOV on the NFP device:** The current NFP PMD supports the PF and + the VFs on a NFP device. However, it is not possible to work with both at the + same time because the VFs require the PF being bound to the NFP PF Linux + netdev driver. Make sure you are working with a kernel with NFP PF support or + get the drivers from the above Github repository and follow the instructions + for building and installing it. + + VFs need to be enabled before they can be used with the PMD. + Before enabling the VFs it is useful to obtain information about the + current NFP PCI device detected by the system: + + .. code-block:: console + + lspci -d19ee: + + Now, for example, configure two virtual functions on a NFP-6xxx device + whose PCI system identity is "0000:03:00.0": + + .. code-block:: console + + echo 2 > /sys/bus/pci/devices/0000:03:00.0/sriov_numvfs + + The result of this command may be shown using lspci again: + + .. code-block:: console + + lspci -d19ee: -k + + Two new PCI devices should appear in the output of the above command. The + -k option shows the device driver, if any, that devices are bound to. + Depending on the modules loaded at this point the new PCI devices may be + bound to nfp_netvf driver. diff --git a/dpdk/doc/guides/nics/octeontx.rst b/dpdk/doc/guides/nics/octeontx.rst new file mode 100644 index 0000000..8e2a2b7 --- /dev/null +++ b/dpdk/doc/guides/nics/octeontx.rst @@ -0,0 +1,177 @@ +..

SPDX-License-Identifier: BSD-3-Clause + Copyright(c) 2016 Intel Corporation. + +Tap Poll Mode Driver +==================== + +The ``rte_eth_tap.c`` PMD creates a device using TAP interfaces on the +local host. The PMD allows for DPDK and the host to communicate using a raw +device interface on the host and in the DPDK application. + +The device created is a TAP device, which sends/receives packet in a raw +format with a L2 header. The usage for a TAP PMD is for connectivity to the +local host using a TAP interface. When the TAP PMD is initialized it will +create a number of tap devices in the host accessed via ``ifconfig -a`` or +``ip`` command. The commands can be used to assign and query the virtual like +device. + +These TAP interfaces can be used with Wireshark or tcpdump or Pktgen-DPDK +along with being able to be used as a network connection to the DPDK +application. The method enable one or more interfaces is to use the +``--vdev=net_tap0`` option on the DPDK application command line. Each +``--vdev=net_tap1`` option given will create an interface named dtap0, dtap1, +and so on. + +The interface name can be changed by adding the ``iface=foo0``, for example:: + + --vdev=net_tap0,iface=foo0 --vdev=net_tap1,iface=foo1, ... + +Normally the PMD will generate a random MAC address, but when testing or with +a static configuration the developer may need a fixed MAC address style. +Using the option ``mac=fixed`` you can create a fixed known MAC address:: + + --vdev=net_tap0,mac=fixed + +The MAC address will have a fixed value with the last octet incrementing by one +for each interface string containing ``mac=fixed``. The MAC address is formatted +as 00:'d':'t':'a':'p':[00-FF]. Convert the characters to hex and you get the +actual MAC address: ``00:64:74:61:70:[00-FF]``. + +It is possible to specify a remote netdevice to capture packets from by adding +``remote=foo1``, for example:: + + --vdev=net_tap,iface=tap0,remote=foo1 + +If a ``remote`` is set, the tap MAC address will be set to match the remote one +just after netdevice creation. Using TC rules, traffic from the remote netdevice +will be redirected to the tap. If the tap is in promiscuous mode, then all +packets will be redirected. In allmulti mode, all multicast packets will be +redirected. + +Using the remote feature is especially useful for capturing traffic from a +netdevice that has no support in the DPDK. It is possible to add explicit +rte_flow rules on the tap PMD to capture specific traffic (see next section for +examples). + +After the DPDK application is started you can send and receive packets on the +interface using the standard rx_burst/tx_burst APIs in DPDK. From the host +point of view you can use any host tool like tcpdump, Wireshark, ping, Pktgen +and others to communicate with the DPDK application. The DPDK application may +not understand network protocols like IPv4/6, UDP or TCP unless the +application has been written to understand these protocols. + +If you need the interface as a real network interface meaning running and has +a valid IP address then you can do this with the following commands:: + + sudo ip link set dtap0 up; sudo ip addr add 192.168.0.250/24 dev dtap0 + sudo ip link set dtap1 up; sudo ip addr add 192.168.1.250/24 dev dtap1 + +Please change the IP addresses as you see fit. + +If routing is enabled on the host you can also communicate with the DPDK App +over the internet via a standard socket layer application as long as you +account for the protocol handing in the application. + +If you have a Network Stack in your DPDK application or something like it you +can utilize that stack to handle the network protocols. Plus you would be able +to address the interface using an IP address assigned to the internal +interface. + +Flow API support +---------------- + +The tap PMD supports major flow API pattern items and actions, when running on +linux kernels above 4.2 ("Flower" classifier required). +The kernel support can be checked with this command:: + + zcat /proc/config.gz | ( grep 'CLS_FLOWER=' || echo 'not supported' ) | + tee -a /dev/stderr | grep -q '=m' && + lsmod | ( grep cls_flower || echo 'try modprobe cls_flower' ) + +Supported items: + +- eth: src and dst (with variable masks), and eth_type (0xffff mask). +- vlan: vid, pcp, tpid, but not eid.

However, if the "last" +item, once masked, is identical to the masked spec, then it is supported. + +Only IPv4/6 and MAC addresses can use a variable mask.

It requires that the ``socat`` utility is installed on the +test system. + +Build DPDK, then pull down Pktgen and build pktgen using the DPDK SDK/Target +used to build the dpdk you pulled down. + +Run pktgen from the pktgen directory in a terminal with a commandline like the +following:: + + sudo ./app/app/x86_64-native-linuxapp-gcc/app/pktgen -l 1-5 -n 4 \ + --proc-type auto --log-level 8 --socket-mem 512,512 --file-prefix pg \ + --vdev=net_tap0 --vdev=net_tap1 -b 05:00.0 -b 05:00.1 \ + -b 04:00.0 -b 04:00.1 -b 04:00.2 -b 04:00.3 \ + -b 81:00.0 -b 81:00.1 -b 81:00.2 -b 81:00.3 \ + -b 82:00.0 -b 83:00.0 -- -T -P -m [2:3].0 -m [4:5].1 \ + -f themes/black-yellow.theme + +.. Note: + + Change the ``-b`` options to blacklist all of your physical ports. The + following command line is all one line. + + Also, ``-f themes/black-yellow.theme`` is optional if the default colors + work on your system configuration. See the Pktgen docs for more + information. + +Verify with ``ifconfig -a`` command in a different xterm window, should have a +``dtap0`` and ``dtap1`` interfaces created. + +Next set the links for the two interfaces to up via the commands below:: + + sudo ip link set dtap0 up; sudo ip addr add 192.168.0.250/24 dev dtap0 + sudo ip link set dtap1 up; sudo ip addr add 192.168.1.250/24 dev dtap1 + +Then use socat to create a loopback for the two interfaces:: + + sudo socat interface:dtap0 interface:dtap1 + +Then on the Pktgen command line interface you can start sending packets using +the commands ``start 0`` and ``start 1`` or you can start both at the same +time with ``start all``. The command ``str`` is an alias for ``start all`` and +``stp`` is an alias for ``stop all``. + +While running you should see the 64 byte counters increasing to verify the +traffic is being looped back. You can use ``set all size XXX`` to change the +size of the packets after you stop the traffic. Use pktgen ``help`` +command to see a list of all commands. You can also use the ``-f`` option to +load commands at startup in command line or Lua script in pktgen. + +RSS specifics +------------- +Packet distribution in TAP is done by the kernel which has a default +distribution. This feature is adding RSS distribution based on eBPF code. +The default eBPF code calculates RSS hash based on Toeplitz algorithm for +a fixed RSS key. It is calculated on fixed packet offsets. For IPv4 and IPv6 it +is calculated over src/dst addresses (8 or 32 bytes for IPv4 or IPv6 +respectively) and src/dst TCP/UDP ports (4 bytes). + +The RSS algorithm is written in file ``tap_bpf_program.c`` which +does not take part in TAP PMD compilation. Instead this file is compiled +in advance to eBPF object file. The eBPF object file is then parsed and +translated into eBPF byte code in the format of C arrays of eBPF +instructions. The C array of eBPF instructions is part of TAP PMD tree and +is taking part in TAP PMD compilation. At run time the C arrays are uploaded to +the kernel via BPF system calls and the RSS hash is calculated by the +kernel. + +It is possible to support different RSS hash algorithms by updating file +``tap_bpf_program.c`` In order to add a new RSS hash algorithm follow these +steps: + +1. Write the new RSS implementation in file ``tap_bpf_program.c`` + +BPF programs which are uploaded to the kernel correspond to +C functions under different ELF sections. + +2. Install ``LLVM`` library and ``clang`` compiler versions 3.7 and above + +3. Compile ``tap_bpf_program.c`` via ``LLVM`` into an object file:: + + clang -O2 -emit-llvm -c tap_bpf_program.c -o - | llc -march=bpf \ + -filetype=obj -o + + +4. Use a tool that receives two parameters: an eBPF object file and a section +name, and prints out the section as a C array of eBPF instructions. +Embed the C array in your TAP PMD tree. + +The C arrays are uploaded to the kernel using BPF system calls. + +``tc`` (traffic control) is a well known user space utility program used to +configure the Linux kernel packet scheduler. It is usually packaged as +part of the ``iproute2`` package. +Since commit 11c39b5e9 ("tc: add eBPF support to f_bpf") ``tc`` can be used +to uploads eBPF code to the kernel and can be patched in order to print the +C arrays of eBPF instructions just before calling the BPF system call. +Please refer to ``iproute2`` package file ``lib/bpf.c`` function +``bpf_prog_load()``. + +An example utility for eBPF instruction generation in the format of C arrays will +be added in next releases + +Systems supporting flow API +--------------------------- + +- "tc flower" classifier requires linux kernel above 4.2 +- eBPF/RSS requires linux kernel above 4.9 + ++--------------------+-----------------------+ +| RH7.3 | No flow rule support | ++--------------------+-----------------------+ +| RH7.4 | No RSS action support | ++--------------------+-----------------------+ +| RH7.5 | No RSS action support | ++--------------------+-----------------------+ +| SLES 15, | No limitation | +| kernel 4.12 | | ++--------------------+-----------------------+ +| Azure Ubuntu 16.04,| No limitation | +| kernel 4.13 | | ++--------------------+-----------------------+ + diff --git a/dpdk/doc/guides/nics/thunderx.rst b/dpdk/doc/guides/nics/thunderx.rst new file mode 100644 index 0000000..2642374 --- /dev/null +++ b/dpdk/doc/guides/nics/thunderx.rst @@ -0,0 +1,337 @@ +..

Therefore +Crypto operations, and in the case of symmetric Crypto operations, the session +and the mbuf being operated on, should be allocated from memory pools created +in the local memory. The buffers should, if possible, remain on the local +processor to obtain the best performance results and buffer descriptors should +be populated with mbufs allocated from a mempool allocated from local memory. + +The run-to-completion model also performs better, especially in the case of +virtual Crypto devices, if the Crypto operation and session and data buffer is +in local memory instead of a remote processor's memory. This is also true for +the pipe-line model provided all logical cores used are located on the same +processor. + +Multiple logical cores should never share the same queue pair for enqueuing +operations or dequeuing operations on the same Crypto device since this would +require global locks and hinder performance. It is however possible to use a +different logical core to dequeue an operation on a queue pair from the logical +core which it was enqueued on. This means that a crypto burst enqueue/dequeue +APIs are a logical place to transition from one logical core to another in a +packet processing pipeline. + + +Device Features and Capabilities +--------------------------------- + +Crypto devices define their functionality through two mechanisms, global device +features and algorithm capabilities.

Sessions are used to manage information such as +expand cipher keys and HMAC IPADs and OPADs, which need to be calculated for a +particular Crypto operation, but are immutable on a packet to packet basis for +a flow. Crypto sessions cache this immutable data in a optimal way for the +underlying PMD and this allows further acceleration of the offload of +Crypto workloads. + +.. figure:: img/cryptodev_sym_sess.* + +The Crypto device framework provides APIs to allocate and initizalize sessions +for crypto devices, where sessions are mempool objects. +It is the application's responsibility to create and manage the session mempools. +This approach allows for different scenarios such as having a single session +mempool for all crypto devices (where the mempool object size is big +enough to hold the private session of any crypto device), as well as having +multiple session mempools of different sizes for better memory usage. + +An application can use ``rte_cryptodev_get_private_session_size()`` to +get the private session size of given crypto device. This function would allow +an application to calculate the max device session size of all crypto devices +to create a single session mempool. +If instead an application creates multiple session mempools, the Crypto device +framework also provides ``rte_cryptodev_get_header_session_size`` to get +the size of an uninitialized session. + +Once the session mempools have been created, ``rte_cryptodev_sym_session_create()`` +is used to allocate an uninitialized session from the given mempool. +The session then must be initialized using ``rte_cryptodev_sym_session_init()`` +for each of the required crypto devices. A symmetric transform chain +is used to specify the operation and its parameters. See the section below for +details on transforms. + +When a session is no longer used, user must call ``rte_cryptodev_sym_session_clear()`` +for each of the crypto devices that are using the session, to free all driver +private session data. Once this is done, session should be freed using +``rte_cryptodev_sym_session_free`` which returns them to their mempool. + + +Transforms and Transform Chaining +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Symmetric Crypto transforms (``rte_crypto_sym_xform``) are the mechanism used +to specify the details of the Crypto operation. For chaining of symmetric +operations such as cipher encrypt and authentication generate, the next pointer +allows transform to be chained together. Crypto devices which support chaining +must publish the chaining of symmetric Crypto operations feature flag. + +Currently there are three transforms types cipher, authentication and AEAD. +Also it is important to note that the order in which the +transforms are passed indicates the order of the chaining. + +.. code-block:: c + + struct rte_crypto_sym_xform { + struct rte_crypto_sym_xform *next; + /**< next xform in chain */ + enum rte_crypto_sym_xform_type type; + /**< xform type */ + union { + struct rte_crypto_auth_xform auth; + /**< Authentication / hash xform */ + struct rte_crypto_cipher_xform cipher; + /**< Cipher xform */ + struct rte_crypto_aead_xform aead; + /**< AEAD xform */ + }; + }; + +The API does not place a limit on the number of transforms that can be chained +together but this will be limited by the underlying Crypto device poll mode +driver which is processing the operation. + +.. figure:: img/crypto_xform_chain.* + + +Symmetric Operations +~~~~~~~~~~~~~~~~~~~~ + +The symmetric Crypto operation structure contains all the mutable data relating +to performing symmetric cryptographic processing on a referenced mbuf data +buffer. It is used for either cipher, authentication, AEAD and chained +operations. + +As a minimum the symmetric operation must have a source data buffer (``m_src``), +a valid session (or transform chain if in session-less mode) and the minimum +authentication/ cipher/ AEAD parameters required depending on the type of operation +specified in the session or the transform +chain. + +.. code-block:: c + + struct rte_crypto_sym_op { + struct rte_mbuf *m_src;

For example, data-centers with disaggregated storage +use storage metadata tables to forward I/O requests to the correct back end +storage cluster, stateful packet inspection will use match incoming +flows to signatures in flow tables to send incoming packets to their +intended deep packet inspection (DPI) devices, and so on. + +EFD is a distributor library that uses perfect hashing to determine a +target/value for a given incoming flow key. It has the following +advantages: first, because it uses perfect hashing it does not store the +key itself and hence lookup performance is not dependent on the key +size. Second, the target/value can be any arbitrary value hence the +system designer and/or operator can better optimize service rates and +inter-cluster network traffic locating. Third, since the storage +requirement is much smaller than a hash-based flow table (i.e. better +fit for CPU cache), EFD can scale to millions of flow keys. Finally, +with the current optimized library implementation, performance is fully +scalable with any number of CPU cores. + +Flow Based Distribution +----------------------- + +Computation Based Schemes +~~~~~~~~~~~~~~~~~~~~~~~~~ + +Flow distribution and/or load balancing can be simply done using a +stateless computation, for instance using round-robin or a simple +computation based on the flow key as an input. For example, a hash +function can be used to direct a certain flow to a target based on +the flow key (e.g. ``h(key) mod n``) where h(key) is the hash value of the +flow key and n is the number of possible targets. + +.. _figure_efd1: + +.. figure:: img/efd_i1.* + + Load Balancing Using Front End Node + +In this scheme (:numref:`figure_efd1`), the front end server/distributor/load balancer +extracts the flow key from the input packet and applies a computation to determine where +this flow should be directed. Intuitively, this scheme is very simple +and requires no state to be kept at the front end node, and hence, +storage requirements are minimum. + +.. _figure_efd2: + +.. figure:: img/efd_i2.* + + Consistent Hashing + +A widely used flow distributor that belongs to the same category of +computation-based schemes is ``consistent hashing``, shown in :numref:`figure_efd2`. +Target destinations (shown in red) are hashed into the same space as the flow +keys (shown in blue), and keys are mapped to the nearest target in a clockwise +fashion. Dynamically adding and removing targets with consistent hashing +requires only K/n keys to be remapped on average, where K is the number of +keys, and n is the number of targets. In contrast, in a traditional hash-based +scheme, a change in the number of targets causes nearly all keys to be +remapped. + +Although computation-based schemes are simple and need very little +storage requirement, they suffer from the drawback that the system +designer/operator can’t fully control the target to assign a specific +key, as this is dictated by the hash function. +Deterministically co-locating of keys together (for example, to minimize +inter-server traffic or to optimize for network traffic conditions, +target load, etc.) is simply not possible. + +Flow-Table Based Schemes +~~~~~~~~~~~~~~~~~~~~~~~~ + +When using a Flow-Table based scheme to handle flow distribution/load +balancing, in contrast with computation-based schemes, the system designer +has the flexibility of assigning a given flow to any given +target. The flow table (e.g. DPDK RTE Hash Library) will simply store +both the flow key and the target value. + +.. _figure_efd3: + +.. figure:: img/efd_i3.* + + Table Based Flow Distribution + +As shown in :numref:`figure_efd3`, when doing a lookup, the flow-table +is indexed with the hash of the flow key and the keys (more than one is possible, +because of hash collision) stored in this index and corresponding values +are retrieved. The retrieved key(s) is matched with the input flow key +and if there is a match the value (target id) is returned. + +The drawback of using a hash table for flow distribution/load balancing +is the storage requirement, since the flow table need to store keys, +signatures and target values. This doesn't allow this scheme to scale to +millions of flow keys. Large tables will usually not fit in +the CPU cache, and hence, the lookup performance is degraded because of +the latency to access the main memory. + +EFD Based Scheme +~~~~~~~~~~~~~~~~ + +EFD combines the advantages of both flow-table based and computation-based +schemes. It doesn't require the large storage necessary for +flow-table based schemes (because EFD doesn't store the key as explained +below), and it supports any arbitrary value for any given key. + +.. _figure_efd4: + +.. figure:: img/efd_i4.* + + Searching for Perfect Hash Function + +The basic idea of EFD is when a given key is to be inserted, a family of +hash functions is searched until the correct hash function that maps the +input key to the correct value is found, as shown in :numref:`figure_efd4`. +However, rather than explicitly storing all keys and their associated values, +EFD stores only indices of hash functions that map keys to values, and +thereby consumes much less space than conventional flow-based tables. +The lookup operation is very simple, similar to a computational-based +scheme: given an input key the lookup operation is reduced to hashing +that key with the correct hash function. + +.. _figure_efd5: + +.. figure:: img/efd_i5.* + + Divide and Conquer for Millions of Keys + +Intuitively, finding a hash function that maps each of a large number +(millions) of input keys to the correct output value is effectively +impossible, as a result EFD, as shown in :numref:`figure_efd5`, +breaks the problem into smaller pieces (divide and conquer). +EFD divides the entire input key set into many small groups. +Each group consists of approximately 20-28 keys (a configurable parameter +for the library), then, for each small group, a brute force search to find +a hash function that produces the correct outputs for each key in the group. + +It should be mentioned that, since the online lookup table for EFD +doesn't store the key itself, the size of the EFD table is independent +of the key size and hence EFD lookup performance which is almost +constant irrespective of the length of the key which is a highly +desirable feature especially for longer keys. + +In summary, EFD is a set separation data structure that supports millions of +keys. It is used to distribute a given key to an intended target. By itself +EFD is not a FIB data structure with an exact match the input flow key. + +.. _Efd_example: + +Example of EFD Library Usage +---------------------------- + +EFD can be used along the data path of many network functions and middleboxes. +As previously mentioned, it can used as an index table for + pairs, meta-data for objects, a flow-level load balancer, etc. +:numref:`figure_efd6` shows an example of using EFD as a flow-level load +balancer, where flows are received at a front end server before being forwarded +to the target back end server for processing. The system designer would +deterministically co-locate flows together in order to minimize cross-server +interaction. +(For example, flows requesting certain webpage objects are co-located +together, to minimize forwarding of common objects across servers). + +.. _figure_efd6: + +.. figure:: img/efd_i6.* + + EFD as a Flow-Level Load Balancer + +As shown in :numref:`figure_efd6`, the front end server will have an EFD table that +stores for each group what is the perfect hash index that satisfies the +correct output. Because the table size is small and fits in cache (since +keys are not stored), it sustains a large number of flows (N*X, where N +is the maximum number of flows served by each back end server of the X +possible targets). + +With an input flow key, the group id is computed (for example, using +last few bits of CRC hash) and then the EFD table is indexed with the +group id to retrieve the corresponding hash index to use. Once the index +is retrieved the key is hashed using this hash function and the result +will be the intended correct target where this flow is supposed to be +processed. + +It should be noted that as a result of EFD not matching the exact key but +rather distributing the flows to a target back end node based on the +perfect hash index, a key that has not been inserted before +will be distributed to a valid target. Hence, a local table which stores +the flows served at each node is used and is +exact matched with the input key to rule out new never seen before +flows. + +.. _Efd_api: + +Library API Overview +-------------------- + +The EFD library API is created with a very similar semantics of a +hash-index or a flow table. The application creates an EFD table for a +given maximum number of flows, a function is called to insert a flow key +with a specific target value, and another function is used to retrieve +target values for a given individual flow key or a bulk of keys. + +EFD Table Create +~~~~~~~~~~~~~~~~ + +The function ``rte_efd_create()`` is used to create and return a pointer +to an EFD table that is sized to hold up to num_flows key. +The online version of the EFD table (the one that does +not store the keys and is used for lookups) will be allocated and +created in the last level cache (LLC) of the socket defined by the +online_socket_bitmask, while the offline EFD table (the one that +stores the keys and is used for key inserts and for computing the +perfect hashing) is allocated and created in the LLC of the socket +defined by offline_socket_bitmask. It should be noted, that for +highest performance the socket id should match that where the thread is +running, i.e. the online EFD lookup table should be created on the same +socket as where the lookup thread is running. + +EFD Insert and Update +~~~~~~~~~~~~~~~~~~~~~ + +The EFD function to insert a key or update a key to a new value is +``rte_efd_update()``. This function will update an existing key to +a new value (target) if the key has already been inserted +before, or will insert the pair if this key has not been inserted +before. It will return 0 upon success. It will return +``EFD_UPDATE_WARN_GROUP_FULL (1)`` if the operation is insert, and the +last available space in the key's group was just used. It will return +``EFD_UPDATE_FAILED (2)`` when the insertion or update has failed (either it +failed to find a suitable perfect hash or the group was full). The function +will return ``EFD_UPDATE_NO_CHANGE (3)`` if there is no change to the EFD +table (i.e, same value already exists). + +.. Note:: + + This function is not multi-thread safe and should only be called + from one thread. + +EFD Lookup +~~~~~~~~~~ + +To lookup a certain key in an EFD table, the function ``rte_efd_lookup()`` +is used to return the value associated with single key. +As previously mentioned, if the key has been inserted, the correct value +inserted is returned, if the key has not been inserted before, +a ‘random’ value (based on hashing of the key) is returned. +For better performance and to decrease the overhead of +function calls per key, it is always recommended to use a bulk lookup +function (simultaneous lookup of multiple keys) instead of a single key +lookup function. ``rte_efd_lookup_bulk()`` is the bulk lookup function, +that looks up num_keys simultaneously stored in the key_list and the +corresponding return values will be returned in the value_list. + +.. Note:: + + This function is multi-thread safe, but there should not be other threads + writing in the EFD table, unless locks are used. + +EFD Delete +~~~~~~~~~~ + +To delete a certain key in an EFD table, the function +``rte_efd_delete()`` can be used. The function returns zero upon success +when the key has been found and deleted. Socket_id is the parameter to +use to lookup the existing value, which is ideally the caller's socket id. +The previous value associated with this key will be returned +in the prev_value argument. + +.. Note:: + + This function is not multi-thread safe and should only be called + from one thread. + +.. _Efd_internals: + +Library Internals +----------------- + +This section provides the brief high-level idea and an overview +of the library internals to accompany the RFC. The intent of this +section is to explain to readers the high-level implementation of +insert, lookup and group rebalancing in the EFD library. + +Insert Function Internals +~~~~~~~~~~~~~~~~~~~~~~~~~ + +As previously mentioned the EFD divides the whole set of keys into +groups of a manageable size (e.g. 28 keys) and then searches for the +perfect hash that satisfies the intended target value for each key. EFD +stores two version of the table: + +- Offline Version (in memory): Only used for the insertion/update + operation, which is less frequent than the lookup operation. In the + offline version the exact keys for each group is stored. When a new + key is added, the hash function is updated that will satisfy the + value for the new key together with the all old keys already inserted + in this group. + +- Online Version (in cache): Used for the frequent lookup operation. In + the online version, as previously mentioned, the keys are not stored + but rather only the hash index for each group. + +.. _figure_efd7: + +.. figure:: img/efd_i7.* + + Group Assignment + +:numref:`figure_efd7` depicts the group assignment for 7 flow keys as an example. +Given a flow key, a hash function (in our implementation CRC hash) is +used to get the group id. As shown in the figure, the groups can be +unbalanced. (We highlight group rebalancing further below). + +.. _figure_efd8: + +.. figure:: img/efd_i8.* + + Perfect Hash Search - Assigned Keys & Target Value + +Focusing on one group that has four keys, :numref:`figure_efd8` depicts the search +algorithm to find the perfect hash function. Assuming that the target +value bit for the keys is as shown in the figure, then the online EFD +table will store a 16 bit hash index and 16 bit lookup table per group +per value bit. + +.. _figure_efd9: + +.. figure:: img/efd_i9.* + + Perfect Hash Search - Satisfy Target Values + +For a given keyX, a hash function ``(h(keyX, seed1) + index * h(keyX, seed2))`` +is used to point to certain bit index in the 16bit lookup_table value, +as shown in :numref:`figure_efd9`. +The insert function will brute force search for all possible values for the +hash index until a non conflicting lookup_table is found. + +.. _figure_efd10: + +.. figure:: img/efd_i10.* + + Finding Hash Index for Conflict Free lookup_table + +For example, since both key3 and key7 have a target bit value of 1, it +is okay if the hash function of both keys point to the same bit in the +lookup table. A conflict will occur if a hash index is used that maps +both Key4 and Key7 to the same index in the lookup_table, +as shown in :numref:`figure_efd10`, since their target value bit are not the same. +Once a hash index is found that produces a lookup_table with no +contradictions, this index is stored for this group. This procedure is +repeated for each bit of target value. + +Lookup Function Internals +~~~~~~~~~~~~~~~~~~~~~~~~~ + +The design principle of EFD is that lookups are much more frequent than +inserts, and hence, EFD's design optimizes for the lookups which are +faster and much simpler than the slower insert procedure (inserts are +slow, because of perfect hash search as previously discussed). + +.. _figure_efd11: + +.. figure:: img/efd_i11.* + + EFD Lookup Operation + +:numref:`figure_efd11` depicts the lookup operation for EFD. Given an input key, +the group id is computed (using CRC hash) and then the hash index for this +group is retrieved from the EFD table. Using the retrieved hash index, +the hash function ``h(key, seed1) + index *h(key, seed2)`` is used which will +result in an index in the lookup_table, the bit corresponding to this +index will be the target value bit. This procedure is repeated for each +bit of the target value. + +Group Rebalancing Function Internals +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +When discussing EFD inserts and lookups, the discussion is simplified by +assuming that a group id is simply a result of hash function. However, +since hashing in general is not perfect and will not always produce a +uniform output, this simplified assumption will lead to unbalanced +groups, i.e., some group will have more keys than other groups. +Typically, and to minimize insert time with an increasing number of keys, +it is preferable that all groups will have a balanced number of keys, so +the brute force search for the perfect hash terminates with a valid hash +index. In order to achieve this target, groups are rebalanced during +runtime inserts, and keys are moved around from a busy group to a less +crowded group as the more keys are inserted. + +.. _figure_efd12: + +.. figure:: img/efd_i12.* + + Runtime Group Rebalancing + +:numref:`figure_efd12` depicts the high level idea of group rebalancing, given an +input key the hash result is split into two parts a chunk id and 8-bit +bin id. A chunk contains 64 different groups and 256 bins (i.e. for any +given bin it can map to 4 distinct groups). When a key is inserted, the +bin id is computed, for example in :numref:`figure_efd12` bin_id=2, +and since each bin can be mapped to one of four different groups (2 bit storage), +the four possible mappings are evaluated and the one that will result in a +balanced key distribution across these four is selected the mapping result +is stored in these two bits. + + +.. _Efd_references: + +References +----------- + +1- EFD is based on collaborative research work between Intel and +Carnegie Mellon University (CMU), interested readers can refer to the paper +“Scaling Up Clustered Network Appliances with ScaleBricks;” Dong Zhou et al. +at SIGCOMM 2015 (`http://conferences.sigcomm.org/sigcomm/2015/pdf/papers/p241.pdf`) +for more information. diff --git a/dpdk/doc/guides/prog_guide/env_abstraction_layer.rst b/dpdk/doc/guides/prog_guide/env_abstraction_layer.rst new file mode 100644 index 0000000..559d0f8 --- /dev/null +++ b/dpdk/doc/guides/prog_guide/env_abstraction_layer.rst @@ -0,0 +1,596 @@ +..

This memory is mmap'd in the application. + +The EAL performs physical memory allocation using mmap() in hugetlbfs (using huge page sizes to increase performance). +This memory is exposed to DPDK service layers such as the :ref:`Mempool Library `. + +At this point, the DPDK services layer will be initialized, then through pthread setaffinity calls, +each execution unit will be assigned to a specific logical core to run as a user-level thread. + +The time reference is provided by the CPU Time-Stamp Counter (TSC) or by the HPET kernel API through a mmap() call. + +Initialization and Core Launching +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Part of the initialization is done by the start function of glibc. +A check is also performed at initialization time to ensure that the micro architecture type chosen in the config file is supported by the CPU. +Then, the main() function is called. The core initialization and launch is done in rte_eal_init() (see the API documentation). +It consist of calls to the pthread library (more specifically, pthread_self(), pthread_create(), and pthread_setaffinity_np()). + +.. _figure_linuxapp_launch: + +.. figure:: img/linuxapp_launch.* + + EAL Initialization in a Linux Application Environment + + +.. note:: + + Initialization of objects, such as memory zones, rings, memory pools, lpm tables and hash tables, + should be done as part of the overall application initialization on the master lcore. + The creation and initialization functions for these objects are not multi-thread safe. + However, once initialized, the objects themselves can safely be used in multiple threads simultaneously. + +Shutdown and Cleanup +~~~~~~~~~~~~~~~~~~~~ + +During the initialization of EAL resources such as hugepage backed memory can be +allocated by core components. The memory allocated during ``rte_eal_init()`` +can be released by calling the ``rte_eal_cleanup()`` function. Refer to the +API documentation for details. + +Multi-process Support +~~~~~~~~~~~~~~~~~~~~~ + +The Linuxapp EAL allows a multi-process as well as a multi-threaded (pthread) deployment model. +See chapter +:ref:`Multi-process Support ` for more details. + +Memory Mapping Discovery and Memory Reservation +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The allocation of large contiguous physical memory is done using the hugetlbfs kernel filesystem. +The EAL provides an API to reserve named memory zones in this contiguous memory. +The physical address of the reserved memory for that memory zone is also returned to the user by the memory zone reservation API. + +.. note:: + + Memory reservations done using the APIs provided by rte_malloc are also backed by pages from the hugetlbfs filesystem. + +PCI Access +~~~~~~~~~~ + +The EAL uses the /sys/bus/pci utilities provided by the kernel to scan the content on the PCI bus. +To access PCI memory, a kernel module called uio_pci_generic provides a /dev/uioX device file +and resource files in /sys +that can be mmap'd to obtain access to PCI address space from the application. +The DPDK-specific igb_uio module can also be used for this. Both drivers use the uio kernel feature (userland driver). + +Per-lcore and Shared Variables +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +.. note:: + + lcore refers to a logical execution unit of the processor, sometimes called a hardware *thread*. + +Shared variables are the default behavior. +Per-lcore variables are implemented using *Thread Local Storage* (TLS) to provide per-thread local storage. + +Logs +~~~~ + +A logging API is provided by EAL. +By default, in a Linux application, logs are sent to syslog and also to the console. +However, the log function can be overridden by the user to use a different logging mechanism. + +Trace and Debug Functions +^^^^^^^^^^^^^^^^^^^^^^^^^ + +There are some debug functions to dump the stack in glibc. +The rte_panic() function can voluntarily provoke a SIG_ABORT, +which can trigger the generation of a core file, readable by gdb. + +CPU Feature Identification +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The EAL can query the CPU at runtime (using the rte_cpu_get_features() function) to determine which CPU features are available. + +User Space Interrupt Event +~~~~~~~~~~~~~~~~~~~~~~~~~~ + ++ User Space Interrupt and Alarm Handling in Host Thread + +The EAL creates a host thread to poll the UIO device file descriptors to detect the interrupts. +Callbacks can be registered or unregistered by the EAL functions for a specific interrupt event +and are called in the host thread asynchronously. +The EAL also allows timed callbacks to be used in the same way as for NIC interrupts. + +.. note:: + + In DPDK PMD, the only interrupts handled by the dedicated host thread are those for link status change + (link up and link down notification) and for sudden device removal. + + ++ RX Interrupt Event + +The receive and transmit routines provided by each PMD don't limit themselves to execute in polling thread mode. +To ease the idle polling with tiny throughput, it's useful to pause the polling and wait until the wake-up event happens. +The RX interrupt is the first choice to be such kind of wake-up event, but probably won't be the only one. + +EAL provides the event APIs for this event-driven thread mode. +Taking linuxapp as an example, the implementation relies on epoll. Each thread can monitor an epoll instance +in which all the wake-up events' file descriptors are added. The event file descriptors are created and mapped to +the interrupt vectors according to the UIO/VFIO spec. +From bsdapp's perspective, kqueue is the alternative way, but not implemented yet. + +EAL initializes the mapping between event file descriptors and interrupt vectors, while each device initializes the mapping +between interrupt vectors and queues. In this way, EAL actually is unaware of the interrupt cause on the specific vector. +The eth_dev driver takes responsibility to program the latter mapping. + +.. note:: + + Per queue RX interrupt event is only allowed in VFIO which supports multiple MSI-X vector. In UIO, the RX interrupt + together with other interrupt causes shares the same vector. In this case, when RX interrupt and LSC(link status change) + interrupt are both enabled(intr_conf.lsc == 1 && intr_conf.rxq == 1), only the former is capable. + +The RX interrupt are controlled/enabled/disabled by ethdev APIs - 'rte_eth_dev_rx_intr_*'. They return failure if the PMD +hasn't support them yet. The intr_conf.rxq flag is used to turn on the capability of RX interrupt per device. + ++ Device Removal Event + +This event is triggered by a device being removed at a bus level. Its +underlying resources may have been made unavailable (i.e. PCI mappings +unmapped). The PMD must make sure that on such occurrence, the application can +still safely use its callbacks. + +This event can be subscribed to in the same way one would subscribe to a link +status change event. The execution context is thus the same, i.e. it is the +dedicated interrupt host thread. + +Considering this, it is likely that an application would want to close a +device having emitted a Device Removal Event. In such case, calling +``rte_eth_dev_close()`` can trigger it to unregister its own Device Removal Event +callback. Care must be taken not to close the device from the interrupt handler +context. It is necessary to reschedule such closing operation. + +Blacklisting +~~~~~~~~~~~~ + +The EAL PCI device blacklist functionality can be used to mark certain NIC ports as blacklisted, +so they are ignored by the DPDK. +The ports to be blacklisted are identified using the PCIe* description (Domain:Bus:Device.Function). + +Misc Functions +~~~~~~~~~~~~~~ + +Locks and atomic operations are per-architecture (i686 and x86_64). + +Memory Segments and Memory Zones (memzone) +------------------------------------------ + +The mapping of physical memory is provided by this feature in the EAL. +As physical memory can have gaps, the memory is described in a table of descriptors, +and each descriptor (called rte_memseg ) describes a contiguous portion of memory. + +On top of this, the memzone allocator's role is to reserve contiguous portions of physical memory. +These zones are identified by a unique name when the memory is reserved. + +The rte_memzone descriptors are also located in the configuration structure. +This structure is accessed using rte_eal_get_configuration(). +The lookup (by name) of a memory zone returns a descriptor containing the physical address of the memory zone. + +Memory zones can be reserved with specific start address alignment by supplying the align parameter +(by default, they are aligned to cache line size). +The alignment value should be a power of two and not less than the cache line size (64 bytes). +Memory zones can also be reserved from either 2 MB or 1 GB hugepages, provided that both are available on the system. + + +Multiple pthread +---------------- + +DPDK usually pins one pthread per core to avoid the overhead of task switching. +This allows for significant performance gains, but lacks flexibility and is not always efficient. + +Power management helps to improve the CPU efficiency by limiting the CPU runtime frequency. +However, alternately it is possible to utilize the idle cycles available to take advantage of +the full capability of the CPU. + +By taking advantage of cgroup, the CPU utilization quota can be simply assigned. +This gives another way to improve the CPU efficiency, however, there is a prerequisite; +DPDK must handle the context switching between multiple pthreads per core. + +For further flexibility, it is useful to set pthread affinity not only to a CPU but to a CPU set. + +EAL pthread and lcore Affinity +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The term "lcore" refers to an EAL thread, which is really a Linux/FreeBSD pthread. +"EAL pthreads" are created and managed by EAL and execute the tasks issued by *remote_launch*. +In each EAL pthread, there is a TLS (Thread Local Storage) called *_lcore_id* for unique identification. +As EAL pthreads usually bind 1:1 to the physical CPU, the *_lcore_id* is typically equal to the CPU ID. + +When using multiple pthreads, however, the binding is no longer always 1:1 between an EAL pthread and a specified physical CPU. +The EAL pthread may have affinity to a CPU set, and as such the *_lcore_id* will not be the same as the CPU ID. +For this reason, there is an EAL long option '--lcores' defined to assign the CPU affinity of lcores. +For a specified lcore ID or ID group, the option allows setting the CPU set for that EAL pthread. + +The format pattern: + --lcores='[@cpu_set][,[@cpu_set],...]' + +'lcore_set' and 'cpu_set' can be a single number, range or a group. + +A number is a "digit([0-9]+)"; a range is "-"; a group is "([,,...])". + +If a '\@cpu_set' value is not supplied, the value of 'cpu_set' will default to the value of 'lcore_set'. + + :: + + For example, "--lcores='1,2@(5-7),(3-5)@(0,2),(0,6),7-8'" which means start 9 EAL thread; + lcore 0 runs on cpuset 0x41 (cpu 0,6); + lcore 1 runs on cpuset 0x2 (cpu 1); + lcore 2 runs on cpuset 0xe0 (cpu 5,6,7); + lcore 3,4,5 runs on cpuset 0x5 (cpu 0,2); + lcore 6 runs on cpuset 0x41 (cpu 0,6); + lcore 7 runs on cpuset 0x80 (cpu 7); + lcore 8 runs on cpuset 0x100 (cpu 8). + +Using this option, for each given lcore ID, the associated CPUs can be assigned. +It's also compatible with the pattern of corelist('-l') option. + +non-EAL pthread support +~~~~~~~~~~~~~~~~~~~~~~~ + +It is possible to use the DPDK execution context with any user pthread (aka. Non-EAL pthreads). +In a non-EAL pthread, the *_lcore_id* is always LCORE_ID_ANY which identifies that it is not an EAL thread with a valid, unique, *_lcore_id*. +Some libraries will use an alternative unique ID (e.g. TID), some will not be impacted at all, and some will work but with limitations (e.g. timer and mempool libraries). + +All these impacts are mentioned in :ref:`known_issue_label` section. + +Public Thread API +~~~~~~~~~~~~~~~~~ + +There are two public APIs ``rte_thread_set_affinity()`` and ``rte_thread_get_affinity()`` introduced for threads. +When they're used in any pthread context, the Thread Local Storage(TLS) will be set/get. + +Those TLS include *_cpuset* and *_socket_id*: + +* *_cpuset* stores the CPUs bitmap to which the pthread is affinitized. + +* *_socket_id* stores the NUMA node of the CPU set. If the CPUs in CPU set belong to different NUMA node, the *_socket_id* will be set to SOCKET_ID_ANY. + + +.. _known_issue_label: + +Known Issues +~~~~~~~~~~~~ + ++ rte_mempool + + The rte_mempool uses a per-lcore cache inside the mempool. + For non-EAL pthreads, ``rte_lcore_id()`` will not return a valid number. + So for now, when rte_mempool is used with non-EAL pthreads, the put/get operations will bypass the default mempool cache and there is a performance penalty because of this bypass. + Only user-owned external caches can be used in a non-EAL context in conjunction with ``rte_mempool_generic_put()`` and ``rte_mempool_generic_get()`` that accept an explicit cache parameter. + ++ rte_ring + + rte_ring supports multi-producer enqueue and multi-consumer dequeue. + However, it is non-preemptive, this has a knock on effect of making rte_mempool non-preemptable. + + .. note:: + + The "non-preemptive" constraint means: + + - a pthread doing multi-producers enqueues on a given ring must not + be preempted by another pthread doing a multi-producer enqueue on + the same ring. + - a pthread doing multi-consumers dequeues on a given ring must not + be preempted by another pthread doing a multi-consumer dequeue on + the same ring. + + Bypassing this constraint may cause the 2nd pthread to spin until the 1st one is scheduled again. + Moreover, if the 1st pthread is preempted by a context that has an higher priority, it may even cause a dead lock. + + This does not mean it cannot be used, simply, there is a need to narrow down the situation when it is used by multi-pthread on the same core. + + 1.

As a header on a block of free or allocated memory - normal case + +#. As a padding header inside a block of memory + +#. As an end-of-memseg marker + +The most important fields in the structure and how they are used are described below. + +.. note:: + + If the usage of a particular field in one of the above three usages is not + described, the field can be assumed to have an undefined value in that + situation, for example, for padding headers only the "state" and "pad" + fields have valid values. + +* heap - this pointer is a reference back to the heap structure from which + this block was allocated. + It is used for normal memory blocks when they are being freed, to add the + newly-freed block to the heap's free-list. + +* prev - this pointer points to the header element/block in the memseg + immediately behind the current one. When freeing a block, this pointer is + used to reference the previous block to check if that block is also free. + If so, then the two free blocks are merged to form a single larger block. + +* next_free - this pointer is used to chain the free-list of unallocated + memory blocks together. + It is only used in normal memory blocks; on ``malloc()`` to find a suitable + free block to allocate and on ``free()`` to add the newly freed element to + the free-list. + +* state - This field can have one of three values: ``FREE``, ``BUSY`` or + ``PAD``. + The former two are to indicate the allocation state of a normal memory block + and the latter is to indicate that the element structure is a dummy structure + at the end of the start-of-block padding, i.e. where the start of the data + within a block is not at the start of the block itself, due to alignment + constraints. + In that case, the pad header is used to locate the actual malloc element + header for the block. + For the end-of-memseg structure, this is always a ``BUSY`` value, which + ensures that no element, on being freed, searches beyond the end of the + memseg for other blocks to merge with into a larger free area. + +* pad - this holds the length of the padding present at the start of the block. + In the case of a normal block header, it is added to the address of the end + of the header to give the address of the start of the data area, i.e. the + value passed back to the application on a malloc. + Within a dummy header inside the padding, this same value is stored, and is + subtracted from the address of the dummy header to yield the address of the + actual block header. + +* size - the size of the data block, including the header itself. + For end-of-memseg structures, this size is given as zero, though it is never + actually checked. + For normal blocks which are being freed, this size value is used in place of + a "next" pointer to identify the location of the next block of memory that + in the case of being ``FREE``, the two free blocks can be merged into one. + +Memory Allocation +^^^^^^^^^^^^^^^^^ + +On EAL initialization, all memsegs are setup as part of the malloc heap. +This setup involves placing a dummy structure at the end with ``BUSY`` state, +which may contain a sentinel value if ``CONFIG_RTE_MALLOC_DEBUG`` is enabled, +and a proper :ref:`element header` with ``FREE`` at the start +for each memseg. +The ``FREE`` element is then added to the ``free_list`` for the malloc heap. + +When an application makes a call to a malloc-like function, the malloc function +will first index the ``lcore_config`` structure for the calling thread, and +determine the NUMA node of that thread. +The NUMA node is used to index the array of ``malloc_heap`` structures which is +passed as a parameter to the ``heap_alloc()`` function, along with the +requested size, type, alignment and boundary parameters. + +The ``heap_alloc()`` function will scan the free_list of the heap, and attempt +to find a free block suitable for storing data of the requested size, with the +requested alignment and boundary constraints. + +When a suitable free element has been identified, the pointer to be returned +to the user is calculated. +The cache-line of memory immediately preceding this pointer is filled with a +struct malloc_elem header. +Because of alignment and boundary constraints, there could be free space at +the start and/or end of the element, resulting in the following behavior: + +#. Check for trailing space. + If the trailing space is big enough, i.e. > 128 bytes, then the free element + is split. + If it is not, then we just ignore it (wasted space). + +#. Check for space at the start of the element. + If the space at the start is small, i.e. <=128 bytes, then a pad header is + used, and the remaining space is wasted. + If, however, the remaining space is greater, then the free element is split. + +The advantage of allocating the memory from the end of the existing element is +that no adjustment of the free list needs to take place - the existing element +on the free list just has its size pointer adjusted, and the following element +has its "prev" pointer redirected to the newly created element. + +Freeing Memory +^^^^^^^^^^^^^^ + +To free an area of memory, the pointer to the start of the data area is passed +to the free function. +The size of the ``malloc_elem`` structure is subtracted from this pointer to get +the element header for the block. +If this header is of type ``PAD`` then the pad length is further subtracted from +the pointer to get the proper element header for the entire block. + +From this element header, we get pointers to the heap from which the block was +allocated and to where it must be freed, as well as the pointer to the previous +element, and via the size field, we can calculate the pointer to the next element. +These next and previous elements are then checked to see if they are also +``FREE``, and if so, they are merged with the current element. +This means that we can never have two ``FREE`` memory blocks adjacent to one +another, as they are always merged into a single block. diff --git a/dpdk/doc/guides/prog_guide/event_ethernet_rx_adapter.rst b/dpdk/doc/guides/prog_guide/event_ethernet_rx_adapter.rst new file mode 100644 index 0000000..4ab87a3 --- /dev/null +++ b/dpdk/doc/guides/prog_guide/event_ethernet_rx_adapter.rst @@ -0,0 +1,142 @@ +..

SPDX-License-Identifier: BSD-3-Clause + Copyright(c) 2017 Intel Corporation. + +Event Device Library +==================== + +The DPDK Event device library is an abstraction that provides the application +with features to schedule events. This is achieved using the PMD architecture +similar to the ethdev or cryptodev APIs, which may already be familiar to the +reader. + +The eventdev framework introduces the event driven programming model. In a +polling model, lcores poll ethdev ports and associated Rx queues directly +to look for a packet. By contrast in an event driven model, lcores call the +scheduler that selects packets for them based on programmer-specified criteria. +The Eventdev library adds support for an event driven programming model, which +offers applications automatic multicore scaling, dynamic load balancing, +pipelining, packet ingress order maintenance and synchronization services to +simplify application packet processing. + +By introducing an event driven programming model, DPDK can support both polling +and event driven programming models for packet processing, and applications are +free to choose whatever model (or combination of the two) best suits their +needs. + +Step-by-step instructions of the eventdev design is available in the `API +Walk-through`_ section later in this document. + +Event struct +------------ + +The eventdev API represents each event with a generic struct, which contains a +payload and metadata required for scheduling by an eventdev. The +``rte_event`` struct is a 16 byte C structure, defined in +``libs/librte_eventdev/rte_eventdev.h``. + +Event Metadata +~~~~~~~~~~~~~~ + +The rte_event structure contains the following metadata fields, which the +application fills in to have the event scheduled as required: + +* ``flow_id`` - The targeted flow identifier for the enq/deq operation. +* ``event_type`` - The source of this event, eg RTE_EVENT_TYPE_ETHDEV or CPU. +* ``sub_event_type`` - Distinguishes events inside the application, that have + the same event_type (see above) +* ``op`` - This field takes one of the RTE_EVENT_OP_* values, and tells the + eventdev about the status of the event - valid values are NEW, FORWARD or + RELEASE. +* ``sched_type`` - Represents the type of scheduling that should be performed + on this event, valid values are the RTE_SCHED_TYPE_ORDERED, ATOMIC and + PARALLEL. +* ``queue_id`` - The identifier for the event queue that the event is sent to. +* ``priority`` - The priority of this event, see RTE_EVENT_DEV_PRIORITY. + +Event Payload +~~~~~~~~~~~~~ + +The rte_event struct contains a union for payload, allowing flexibility in what +the actual event being scheduled is. The payload is a union of the following: + +* ``uint64_t u64`` +* ``void *event_ptr`` +* ``struct rte_mbuf *mbuf`` + +These three items in a union occupy the same 64 bits at the end of the rte_event +structure. The application can utilize the 64 bits directly by accessing the +u64 variable, while the event_ptr and mbuf are provided as convenience +variables. For example the mbuf pointer in the union can used to schedule a +DPDK packet. + +Queues +~~~~~~ + +An event queue is a queue containing events that are scheduled by the event +device. An event queue contains events of different flows associated with +scheduling types, such as atomic, ordered, or parallel. + +Queue All Types Capable +^^^^^^^^^^^^^^^^^^^^^^^ + +If RTE_EVENT_DEV_CAP_QUEUE_ALL_TYPES capability bit is set in the event device, +then events of any type may be sent to any queue. Otherwise, the queues only +support events of the type that it was created with. + +Queue All Types Incapable +^^^^^^^^^^^^^^^^^^^^^^^^^ + +In this case, each stage has a specified scheduling type. The application +configures each queue for a specific type of scheduling, and just enqueues all +events to the eventdev. An example of a PMD of this type is the eventdev +software PMD. + +The Eventdev API supports the following scheduling types per queue: + +* Atomic +* Ordered +* Parallel + +Atomic, Ordered and Parallel are load-balanced scheduling types: the output +of the queue can be spread out over multiple CPU cores. + +Atomic scheduling on a queue ensures that a single flow is not present on two +different CPU cores at the same time. Ordered allows sending all flows to any +core, but the scheduler must ensure that on egress the packets are returned to +ingress order on downstream queue enqueue. Parallel allows sending all flows +to all CPU cores, without any re-ordering guarantees. + +Single Link Flag +^^^^^^^^^^^^^^^^ + +There is a SINGLE_LINK flag which allows an application to indicate that only +one port will be connected to a queue. Queues configured with the single-link +flag follow a FIFO like structure, maintaining ordering but it is only capable +of being linked to a single port (see below for port and queue linking details). + + +Ports +~~~~~ + +Ports are the points of contact between worker cores and the eventdev. The +general use-case will see one CPU core using one port to enqueue and dequeue +events from an eventdev. Ports are linked to queues in order to retrieve events +from those queues (more details in `Linking Queues and Ports`_ below). + + +API Walk-through +---------------- + +This section will introduce the reader to the eventdev API, showing how to +create and configure an eventdev and use it for a two-stage atomic pipeline +with a single core for TX.

Repeat this step for each queue, starting from +0 and ending at ``nb_event_queues - 1`` from the event_dev config above. + +.. code-block:: c + + struct rte_event_queue_conf atomic_conf = { + .schedule_type = RTE_SCHED_TYPE_ATOMIC, + .priority = RTE_EVENT_DEV_PRIORITY_NORMAL, + .nb_atomic_flows = 1024, + .nb_atomic_order_sequences = 1024, + }; + int dev_id = 0; + int queue_id = 0; + int err = rte_event_queue_setup(dev_id, queue_id, &atomic_conf); + +The remainder of this walk-through assumes that the queues are configured as +follows: + + * id 0, atomic queue #1 + * id 1, atomic queue #2 + * id 2, single-link queue + +Setting up Ports +~~~~~~~~~~~~~~~~ + +Once queues are set up successfully, create the ports as required. Each port +should be set up with its corresponding port_conf type, worker for worker cores, +rx and tx for the RX and TX cores: + +.. code-block:: c + + struct rte_event_port_conf rx_conf = { + .dequeue_depth = 128, + .enqueue_depth = 128, + .new_event_threshold = 1024, + }; + struct rte_event_port_conf worker_conf = { + .dequeue_depth = 16, + .enqueue_depth = 64, + .new_event_threshold = 4096, + }; + struct rte_event_port_conf tx_conf = { + .dequeue_depth = 128, + .enqueue_depth = 128, + .new_event_threshold = 4096, + }; + int dev_id = 0; + int port_id = 0; + int err = rte_event_port_setup(dev_id, port_id, &CORE_FUNCTION_conf); + +It is now assumed that: + + * port 0: RX core + * ports 1,2,3,4: Workers + * port 5: TX core + +Linking Queues and Ports +~~~~~~~~~~~~~~~~~~~~~~~~ + +The final step is to "wire up" the ports to the queues. After this, the +eventdev is capable of scheduling events, and when cores request work to do, +the correct events are provided to that core. Note that the RX core takes input +from eg: a NIC so it is not linked to any eventdev queues. + +Linking all workers to atomic queues, and the TX core to the single-link queue +can be achieved like this: + +.. code-block:: c + + uint8_t port_id = 0; + uint8_t atomic_qs[] = {0, 1}; + uint8_t single_link_q = 2; + uint8_t tx_port_id = 5; + uin8t_t priority = RTE_EVENT_DEV_PRIORITY_NORMAL; + + for(int i = 0; i < 4; i++) { + int worker_port = i + 1; + int links_made = rte_event_port_link(dev_id, worker_port, atomic_qs, NULL, 2); + } + int links_made = rte_event_port_link(dev_id, tx_port_id, &single_link_q, &priority, 1); + +Starting the EventDev +~~~~~~~~~~~~~~~~~~~~~ + +A single function call tells the eventdev instance to start processing +events. Note that all queues must be linked to for the instance to start, as +if any queue is not linked to, enqueuing to that queue will cause the +application to backpressure and eventually stall due to no space in the +eventdev. + +.. code-block:: c + + int err = rte_event_dev_start(dev_id); + +Ingress of New Events +~~~~~~~~~~~~~~~~~~~~~ + +Now that the eventdev is set up, and ready to receive events, the RX core must +enqueue some events into the system for it to schedule. The events to be +scheduled are ordinary DPDK packets, received from an eth_rx_burst() as normal. +The following code shows how those packets can be enqueued into the eventdev: + +.. code-block:: c + + const uint16_t nb_rx = rte_eth_rx_burst(eth_port, 0, mbufs, BATCH_SIZE); + + for (i = 0; i < nb_rx; i++) { + ev[i].flow_id = mbufs[i]->hash.rss; + ev[i].op = RTE_EVENT_OP_NEW; + ev[i].sched_type = RTE_SCHED_TYPE_ATOMIC; + ev[i].queue_id = 0; + ev[i].event_type = RTE_EVENT_TYPE_ETHDEV; + ev[i].sub_event_type = 0; + ev[i].priority = RTE_EVENT_DEV_PRIORITY_NORMAL; + ev[i].mbuf = mbufs[i]; + } + + const int nb_tx = rte_event_enqueue_burst(dev_id, port_id, ev, nb_rx); + if (nb_tx != nb_rx) { + for(i = nb_tx; i < nb_rx; i++) + rte_pktmbuf_free(mbufs[i]); + } + +Forwarding of Events +~~~~~~~~~~~~~~~~~~~~ + +Now that the RX core has injected events, there is work to be done by the +workers. Note that each worker will dequeue as many events as it can in a burst, +process each one individually, and then burst the packets back into the +eventdev. + +The worker can lookup the events source from ``event.queue_id``, which should +indicate to the worker what workload needs to be performed on the event. +Once done, the worker can update the ``event.queue_id`` to a new value, to send +the event to the next stage in the pipeline. + +.. code-block:: c + + int timeout = 0; + struct rte_event events[BATCH_SIZE]; + uint16_t nb_rx = rte_event_dequeue_burst(dev_id, worker_port_id, events, BATCH_SIZE, timeout); + + for (i = 0; i < nb_rx; i++) { + /* process mbuf using events[i].queue_id as pipeline stage */ + struct rte_mbuf *mbuf = events[i].mbuf; + /* Send event to next stage in pipeline */ + events[i].queue_id++; + } + + uint16_t nb_tx = rte_event_enqueue_burst(dev_id, port_id, events, nb_rx); + + +Egress of Events +~~~~~~~~~~~~~~~~ + +Finally, when the packet is ready for egress or needs to be dropped, we need +to inform the eventdev that the packet is no longer being handled by the +application. This can be done by calling dequeue() or dequeue_burst(), which +indicates that the previous burst of packets is no longer in use by the +application. + +An event driven worker thread has following typical workflow on fastpath: + +.. code-block:: c + + while (1) { + rte_event_dequeue_burst(...); + (event processing) + rte_event_enqueue_burst(...); + } + + +Summary +------- + +The eventdev library allows an application to easily schedule events as it +requires, either using a run-to-completion or pipeline processing model. The +queues and ports abstract the logical functionality of an eventdev, providing +the application with a generic method to schedule events. With the flexible +PMD infrastructure applications benefit of improvements in existing eventdevs +and additions of new ones without modification. diff --git a/dpdk/doc/guides/prog_guide/ext_app_lib_make_help.rst b/dpdk/doc/guides/prog_guide/ext_app_lib_make_help.rst new file mode 100644 index 0000000..7e8e9fd --- /dev/null +++ b/dpdk/doc/guides/prog_guide/ext_app_lib_make_help.rst @@ -0,0 +1,98 @@ +..

SPDX-License-Identifier: BSD-3-Clause + Copyright(c) 2017 Intel Corporation. + +Generic Receive Offload Library +=============================== + +Generic Receive Offload (GRO) is a widely used SW-based offloading +technique to reduce per-packet processing overheads. By reassembling +small packets into larger ones, GRO enables applications to process +fewer large packets directly, thus reducing the number of packets to +be processed. To benefit DPDK-based applications, like Open vSwitch, +DPDK also provides own GRO implementation. In DPDK, GRO is implemented +as a standalone library. Applications explicitly use the GRO library to +reassemble packets. + +Overview +-------- + +In the GRO library, there are many GRO types which are defined by packet +types. One GRO type is in charge of process one kind of packets. For +example, TCP/IPv4 GRO processes TCP/IPv4 packets. + +Each GRO type has a reassembly function, which defines own algorithm and +table structure to reassemble packets. We assign input packets to the +corresponding GRO functions by MBUF->packet_type. + +The GRO library doesn't check if input packets have correct checksums and +doesn't re-calculate checksums for merged packets. The GRO library +assumes the packets are complete (i.e., MF==0 && frag_off==0), when IP +fragmentation is possible (i.e., DF==0). Additionally, it complies RFC +6864 to process the IPv4 ID field. + +Currently, the GRO library provides GRO supports for TCP/IPv4 packets and +VxLAN packets which contain an outer IPv4 header and an inner TCP/IPv4 +packet. + +Two Sets of API +--------------- + +For different usage scenarios, the GRO library provides two sets of API. +The one is called the lightweight mode API, which enables applications to +merge a small number of packets rapidly; the other is called the +heavyweight mode API, which provides fine-grained controls to +applications and supports to merge a large number of packets. + +Lightweight Mode API +~~~~~~~~~~~~~~~~~~~~ + +The lightweight mode only has one function ``rte_gro_reassemble_burst()``, +which process N packets at a time. Using the lightweight mode API to +merge packets is very simple. Calling ``rte_gro_reassemble_burst()`` is +enough. The GROed packets are returned to applications as soon as it +finishes. + +In ``rte_gro_reassemble_burst()``, table structures of different GRO +types are allocated in the stack. This design simplifies applications' +operations. However, limited by the stack size, the maximum number of +packets that ``rte_gro_reassemble_burst()`` can process in an invocation +should be less than or equal to ``RTE_GRO_MAX_BURST_ITEM_NUM``. + +Heavyweight Mode API +~~~~~~~~~~~~~~~~~~~~ + +Compared with the lightweight mode, using the heavyweight mode API is +relatively complex. Firstly, applications need to create a GRO context +by ``rte_gro_ctx_create()``. ``rte_gro_ctx_create()`` allocates tables +structures in the heap and stores their pointers in the GRO context. +Secondly, applications use ``rte_gro_reassemble()`` to merge packets. +If input packets have invalid parameters, ``rte_gro_reassemble()`` +returns them to applications. For example, packets of unsupported GRO +types or TCP SYN packets are returned. Otherwise, the input packets are +either merged with the existed packets in the tables or inserted into the +tables. Finally, applications use ``rte_gro_timeout_flush()`` to flush +packets from the tables, when they want to get the GROed packets. + +Note that all update/lookup operations on the GRO context are not thread +safe. So if different processes or threads want to access the same +context object simultaneously, some external syncing mechanisms must be +used. + +Reassembly Algorithm +-------------------- + +The reassembly algorithm is used for reassembling packets. In the GRO +library, different GRO types can use different algorithms. In this +section, we will introduce an algorithm, which is used by TCP/IPv4 GRO +and VxLAN GRO. + +Challenges +~~~~~~~~~~ + +The reassembly algorithm determines the efficiency of GRO. There are two +challenges in the algorithm design: + +- a high cost algorithm/implementation would cause packet dropping in a + high speed network. + +- packet reordering makes it hard to merge packets. For example, Linux + GRO fails to merge packets when encounters packet reordering. + +The above two challenges require our algorithm is: + +- lightweight enough to scale fast networking speed + +- capable of handling packet reordering + +In DPDK GRO, we use a key-based algorithm to address the two challenges. + +Key-based Reassembly Algorithm +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +:numref:`figure_gro-key-algorithm` illustrates the procedure of the +key-based algorithm. Packets are classified into "flows" by some header +fields (we call them as "key"). To process an input packet, the algorithm +searches for a matched "flow" (i.e., the same value of key) for the +packet first, then checks all packets in the "flow" and tries to find a +"neighbor" for it. If find a "neighbor", merge the two packets together. +If can't find a "neighbor", store the packet into its "flow". If can't +find a matched "flow", insert a new "flow" and store the packet into the +"flow". + +.. note:: + Packets in the same "flow" that can't merge are always caused + by packet reordering. + +The key-based algorithm has two characters: + +- classifying packets into "flows" to accelerate packet aggregation is + simple (address challenge 1). + +- storing out-of-order packets makes it possible to merge later (address + challenge 2). + +.. _figure_gro-key-algorithm: + +.. figure:: img/gro-key-algorithm.* + :align: center + + Key-based Reassembly Algorithm + +TCP/IPv4 GRO +------------ + +The table structure used by TCP/IPv4 GRO contains two arrays: flow array +and item array.

SPDX-License-Identifier: BSD-3-Clause + Copyright(c) 2017 Intel Corporation. + +Generic Segmentation Offload Library +==================================== + +Overview +-------- +Generic Segmentation Offload (GSO) is a widely used software implementation of +TCP Segmentation Offload (TSO), which reduces per-packet processing overhead. +Much like TSO, GSO gains performance by enabling upper layer applications to +process a smaller number of large packets (e.g. MTU size of 64KB), instead of +processing higher numbers of small packets (e.g. MTU size of 1500B), thus +reducing per-packet overhead. + +For example, GSO allows guest kernel stacks to transmit over-sized TCP segments +that far exceed the kernel interface's MTU; this eliminates the need to segment +packets within the guest, and improves the data-to-overhead ratio of both the +guest-host link, and PCI bus. The expectation of the guest network stack in this +scenario is that segmentation of egress frames will take place either in the NIC +HW, or where that hardware capability is unavailable, either in the host +application, or network stack. + +Bearing that in mind, the GSO library enables DPDK applications to segment +packets in software. Note however, that GSO is implemented as a standalone +library, and not via a 'fallback' mechanism (i.e. for when TSO is unsupported +in the underlying hardware); that is, applications must explicitly invoke the +GSO library to segment packets. The size of GSO segments ``(segsz)`` is +configurable by the application. + +Limitations +----------- + +#. The GSO library doesn't check if input packets have correct checksums. + +#. In addition, the GSO library doesn't re-calculate checksums for segmented + packets (that task is left to the application). + +#. IP fragments are unsupported by the GSO library. + +#. The egress interface's driver must support multi-segment packets. + +#. Currently, the GSO library supports the following IPv4 packet types: + + - TCP + - VxLAN + - GRE + + See `Supported GSO Packet Types`_ for further details. + +Packet Segmentation +------------------- + +The ``rte_gso_segment()`` function is the GSO library's primary +segmentation API. + +Before performing segmentation, an application must create a GSO context object +``(struct rte_gso_ctx)``, which provides the library with some of the +information required to understand how the packet should be segmented. Refer to +`How to Segment a Packet`_ for additional details on same. Once the GSO context +has been created, and populated, the application can then use the +``rte_gso_segment()`` function to segment packets. + +The GSO library typically stores each segment that it creates in two parts: the +first part contains a copy of the original packet's headers, while the second +part contains a pointer to an offset within the original packet. This mechanism +is explained in more detail in `GSO Output Segment Format`_. + +The GSO library supports both single- and multi-segment input mbufs. + +GSO Output Segment Format +~~~~~~~~~~~~~~~~~~~~~~~~~ +To reduce the number of expensive memcpy operations required when segmenting a +packet, the GSO library typically stores each segment that it creates as a +two-part mbuf (technically, this is termed a 'two-segment' mbuf; however, since +the elements produced by the API are also called 'segments', for clarity the +term 'part' is used here instead). + +The first part of each output segment is a direct mbuf and contains a copy of +the original packet's headers, which must be prepended to each output segment. +These headers are copied from the original packet into each output segment. + +The second part of each output segment, represents a section of data from the +original packet, i.e. a data segment. Rather than copy the data directly from +the original packet into the output segment (which would impact performance +considerably), the second part of each output segment is an indirect mbuf, +which contains no actual data, but simply points to an offset within the +original packet. + +The combination of the 'header' segment and the 'data' segment constitutes a +single logical output GSO segment of the original packet. This is illustrated +in :numref:`figure_gso-output-segment-format`. + +.. _figure_gso-output-segment-format: + +.. figure:: img/gso-output-segment-format.* + :align: center + + Two-part GSO output segment + +In one situation, the output segment may contain additional 'data' segments. +This only occurs when: + +- the input packet on which GSO is to be performed is represented by a + multi-segment mbuf. + +- the output segment is required to contain data that spans the boundaries + between segments of the input multi-segment mbuf. + +The GSO library traverses each segment of the input packet, and produces +numerous output segments; for optimal performance, the number of output +segments is kept to a minimum. Consequently, the GSO library maximizes the +amount of data contained within each output segment; i.e. each output segment +``segsz`` bytes of data. The only exception to this is in the case of the very +final output segment; if ``pkt_len`` % ``segsz``, then the final segment is +smaller than the rest. + +In order for an output segment to meet its MSS, it may need to include data from +multiple input segments. Due to the nature of indirect mbufs (each indirect mbuf +can point to only one direct mbuf), the solution here is to add another indirect +mbuf to the output segment; this additional segment then points to the next +input segment. If necessary, this chaining process is repeated, until the sum of +all of the data 'contained' in the output segment reaches ``segsz``. This +ensures that the amount of data contained within each output segment is uniform, +with the possible exception of the last segment, as previously described. + +:numref:`figure_gso-three-seg-mbuf` illustrates an example of a three-part +output segment. In this example, the output segment needs to include data from +the end of one input segment, and the beginning of another. To achieve this, +an additional indirect mbuf is chained to the second part of the output segment, +and is attached to the next input segment (i.e. it points to the data in the +next input segment). + +.. _figure_gso-three-seg-mbuf: + +.. figure:: img/gso-three-seg-mbuf.* + :align: center + + Three-part GSO output segment + +Supported GSO Packet Types +-------------------------- + +TCP/IPv4 GSO +~~~~~~~~~~~~ +TCP/IPv4 GSO supports segmentation of suitably large TCP/IPv4 packets, which +may also contain an optional VLAN tag. + +VxLAN GSO +~~~~~~~~~ +VxLAN packets GSO supports segmentation of suitably large VxLAN packets, +which contain an outer IPv4 header, inner TCP/IPv4 headers, and optional +inner and/or outer VLAN tag(s). + +GRE GSO +~~~~~~~ +GRE GSO supports segmentation of suitably large GRE packets, which contain +an outer IPv4 header, inner TCP/IPv4 headers, and an optional VLAN tag. + +How to Segment a Packet +----------------------- + +To segment an outgoing packet, an application must: + +#. First create a GSO context ``(struct rte_gso_ctx)``; this contains: + + - a pointer to the mbuf pool for allocating the direct buffers, which are + used to store the GSO segments' packet headers. + + - a pointer to the mbuf pool for allocating indirect buffers, which are + used to locate GSO segments' packet payloads. + + .. note:: + + An application may use the same pool for both direct and indirect + buffers. However, since indirect mbufs simply store a pointer, the + application may reduce its memory consumption by creating a separate memory + pool, containing smaller elements, for the indirect pool. + + + - the size of each output segment, including packet headers and payload, + measured in bytes. + + - the bit mask of required GSO types. The GSO library uses the same macros as + those that describe a physical device's TX offloading capabilities (i.e. + ``DEV_TX_OFFLOAD_*_TSO``) for gso_types. For example, if an application + wants to segment TCP/IPv4 packets, it should set gso_types to + ``DEV_TX_OFFLOAD_TCP_TSO``. The only other supported values currently + supported for gso_types are ``DEV_TX_OFFLOAD_VXLAN_TNL_TSO``, and + ``DEV_TX_OFFLOAD_GRE_TNL_TSO``; a combination of these macros is also + allowed. + + - a flag, that indicates whether the IPv4 headers of output segments should + contain fixed or incremental ID values. + +2. Set the appropriate ol_flags in the mbuf. + + - The GSO library use the value of an mbuf's ``ol_flags`` attribute to + to determine how a packet should be segmented. It is the application's + responsibility to ensure that these flags are set. + + - For example, in order to segment TCP/IPv4 packets, the application should + add the ``PKT_TX_IPV4`` and ``PKT_TX_TCP_SEG`` flags to the mbuf's + ol_flags. + + - If checksum calculation in hardware is required, the application should + also add the ``PKT_TX_TCP_CKSUM`` and ``PKT_TX_IP_CKSUM`` flags. + +#. Check if the packet should be processed. Packets with one of the + following properties are not processed and are returned immediately: + + - Packet length is less than ``segsz`` (i.e. GSO is not required). + + - Packet type is not supported by GSO library (see + `Supported GSO Packet Types`_). + + - Application has not enabled GSO support for the packet type. + + - Packet's ol_flags have been incorrectly set. + +#. Allocate space in which to store the output GSO segments. If the amount of + space allocated by the application is insufficient, segmentation will fail. + +#. Invoke the GSO segmentation API, ``rte_gso_segment()``. + +#. If required, update the L3 and L4 checksums of the newly-created segments. + For tunneled packets, the outer IPv4 headers' checksums should also be + updated. Alternatively, the application may offload checksum calculation + to HW. + diff --git a/dpdk/doc/guides/prog_guide/glossary.rst b/dpdk/doc/guides/prog_guide/glossary.rst new file mode 100644 index 0000000..e101bc0 --- /dev/null +++ b/dpdk/doc/guides/prog_guide/glossary.rst @@ -0,0 +1,247 @@ +..

If an entry with the specified key is found in the hash (lookup hit), + then the position of the entry is returned, otherwise (lookup miss) a negative value is returned. + +Apart from these method explained above, the API allows the user three more options: + +* Add / lookup / delete with key and precomputed hash: Both the key and its precomputed hash are provided as input. This allows + the user to perform these operations faster, as hash is already computed. + +* Add / lookup with key and data: A pair of key-value is provided as input. This allows the user to store + not only the key, but also data which may be either a 8-byte integer or a pointer to external data (if data size is more than 8 bytes). + +* Combination of the two options above: User can provide key, precomputed hash and data. + +Also, the API contains a method to allow the user to look up entries in bursts, achieving higher performance +than looking up individual entries, as the function prefetches next entries at the time it is operating +with the first ones, which reduces significantly the impact of the necessary memory accesses. +Notice that this method uses a pipeline of 8 entries (4 stages of 2 entries), so it is highly recommended +to use at least 8 entries per burst. + +The actual data associated with each key can be either managed by the user using a separate table that +mirrors the hash in terms of number of entries and position of each entry, +as shown in the Flow Classification use case describes in the following sections, +or stored in the hash table itself. + +The example hash tables in the L2/L3 Forwarding sample applications defines which port to forward a packet to based on a packet flow identified by the five-tuple lookup. +However, this table could also be used for more sophisticated features and provide many other functions and actions that could be performed on the packets and flows. + +Multi-process support +--------------------- + +The hash library can be used in a multi-process environment, minding that only lookups are thread-safe. +The only function that can only be used in single-process mode is rte_hash_set_cmp_func(), which sets up +a custom compare function, which is assigned to a function pointer (therefore, it is not supported in +multi-process mode). + +Implementation Details +---------------------- + +The hash table has two main tables: + +* First table is an array of entries which is further divided into buckets, + with the same number of consecutive array entries in each bucket. Each entry contains the computed primary + and secondary hashes of a given key (explained below), and an index to the second table. + +* The second table is an array of all the keys stored in the hash table and its data associated to each key. + +The hash library uses the cuckoo hash method to resolve collisions. +For any input key, there are two possible buckets (primary and secondary/alternative location) +where that key can be stored in the hash, therefore only the entries within those bucket need to be examined +when the key is looked up. +The lookup speed is achieved by reducing the number of entries to be scanned from the total +number of hash entries down to the number of entries in the two hash buckets, +as opposed to the basic method of linearly scanning all the entries in the array. +The hash uses a hash function (configurable) to translate the input key into a 4-byte key signature. +The bucket index is the key signature modulo the number of hash buckets. + +Once the buckets are identified, the scope of the hash add, +delete and lookup operations is reduced to the entries in those buckets (it is very likely that entries are in the primary bucket). + +To speed up the search logic within the bucket, each hash entry stores the 4-byte key signature together with the full key for each hash entry. +For large key sizes, comparing the input key against a key from the bucket can take significantly more time than +comparing the 4-byte signature of the input key against the signature of a key from the bucket. +Therefore, the signature comparison is done first and the full key comparison done only when the signatures matches. +The full key comparison is still necessary, as two input keys from the same bucket can still potentially have the same 4-byte hash signature, +although this event is relatively rare for hash functions providing good uniform distributions for the set of input keys. + +Example of lookup: + +First of all, the primary bucket is identified and entry is likely to be stored there. +If signature was stored there, we compare its key against the one provided and return the position +where it was stored and/or the data associated to that key if there is a match. +If signature is not in the primary bucket, the secondary bucket is looked up, where same procedure +is carried out. If there is no match there either, key is considered not to be in the table. + +Example of addition: + +Like lookup, the primary and secondary buckets are identified. If there is an empty slot in +the primary bucket, primary and secondary signatures are stored in that slot, key and data (if any) are added to +the second table and an index to the position in the second table is stored in the slot of the first table. +If there is no space in the primary bucket, one of the entries on that bucket is pushed to its alternative location, +and the key to be added is inserted in its position. +To know where the alternative bucket of the evicted entry is, the secondary signature is looked up and alternative bucket index +is calculated from doing the modulo, as seen above. If there is room in the alternative bucket, the evicted entry +is stored in it. If not, same process is repeated (one of the entries gets pushed) until a non full bucket is found. +Notice that despite all the entry movement in the first table, the second table is not touched, which would impact +greatly in performance. + +In the very unlikely event that table enters in a loop where same entries are being evicted indefinitely, +key is considered not able to be stored. +With random keys, this method allows the user to get around 90% of the table utilization, without +having to drop any stored entry (LRU) or allocate more memory (extended buckets). + +Entry distribution in hash table +-------------------------------- + +As mentioned above, Cuckoo hash implementation pushes elements out of their bucket, +if there is a new entry to be added which primary location coincides with their current bucket, +being pushed to their alternative location. +Therefore, as user adds more entries to the hash table, distribution of the hash values +in the buckets will change, being most of them in their primary location and a few in +their secondary location, which the later will increase, as table gets busier. +This information is quite useful, as performance may be lower as more entries +are evicted to their secondary location. + +See the tables below showing example entry distribution as table utilization increases. + +.. _table_hash_lib_1: + +.. table:: Entry

tables above are the average maximum table + utilization with random keys and using Jenkins hash function. + +Use Case: Flow Classification +----------------------------- + +Flow classification is used to map each input packet to the connection/flow it belongs to. +This operation is necessary as the processing of each input packet is usually done in the context of their connection, +so the same set of operations is applied to all the packets from the same flow. + +Applications using flow classification typically have a flow table to manage, with each separate flow having an entry associated with it in this table. +The size of the flow table entry is application specific, with typical values of 4, 16, 32 or 64 bytes. + +Each application using flow classification typically has a mechanism defined to uniquely identify a flow based on +a number of fields read from the input packet that make up the flow key. +One example is to use the DiffServ 5-tuple made up of the following fields of the IP and transport layer packet headers: +Source IP Address, Destination IP Address, Protocol, Source Port, Destination Port. + +The DPDK hash provides a generic method to implement an application specific flow classification mechanism. +Given a flow table implemented as an array, the application should create a hash object with the same number of entries as the flow table and +with the hash key size set to the number of bytes in the selected flow key. + +The flow table operations on the application side are described below: + +* Add flow: Add the flow key to hash. + If the returned

They either return a pointer to valid mbuf that contains reassembled packet, +or NULL (if the packet can't be reassembled for some reason). + +These functions are responsible for: + +#. Search the Fragment Table for entry with packet's . + +#. If the entry is found, then check if that entry already timed-out. + If yes, then free all previously received fragments, and remove information about them from the entry. + +#. If no entry with such key is found, then try to create a new one by one of two ways: + + a) Use as empty entry. + + b) Delete a timed-out entry, free mbufs associated with it mbufs and store a new entry with specified key in it. + +#. Update the entry with new fragment information and check if a packet can be reassembled + (the packet's entry contains all fragments). + + a) If yes, then, reassemble the packet, mark table's entry as empty and return the reassembled mbuf to the caller. + + b) If no, then return a NULL to the caller. + +If at any stage of packet processing an error is encountered +(e.g: can't insert new entry into the Fragment Table, or invalid/timed-out fragment), +then the function will free all associated with the packet fragments, +mark the table entry as invalid and return NULL to the caller. + +Debug logging and Statistics Collection +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The RTE_LIBRTE_IP_FRAG_TBL_STAT config macro controls statistics collection for the Fragment Table. +This macro is not enabled by default. + +The RTE_LIBRTE_IP_FRAG_DEBUG controls debug logging of IP fragments processing and reassembling. +This macro is disabled by default. +Note that while logging contains a lot of detailed information, +it slows down packet processing and might cause the loss of a lot of packets. diff --git a/dpdk/doc/guides/prog_guide/kernel_nic_interface.rst b/dpdk/doc/guides/prog_guide/kernel_nic_interface.rst new file mode 100644 index 0000000..8fa13fa --- /dev/null +++ b/dpdk/doc/guides/prog_guide/kernel_nic_interface.rst @@ -0,0 +1,143 @@ +..

poll all KNI active devices for the rx_q. +If an mbuf is dequeued, it will be converted to a sk_buff and sent to the net stack via netif_rx(). +The dequeued mbuf must be freed, so the same pointer is sent back in the free_q FIFO. + +The RX thread, in the same main loop, polls this FIFO and frees the mbuf after dequeuing it. + +Use Case: Egress +---------------- + +For packet egress the DPDK application must first enqueue several mbufs to create an mbuf cache on the kernel side. + +The packet is received from the Linux net stack, by calling the kni_net_tx() callback. +The mbuf is dequeued (without waiting due the cache) and filled with data from sk_buff. +The sk_buff is then freed and the mbuf sent in the tx_q FIFO. + +The DPDK TX thread dequeues the mbuf and sends it to the PMD (via rte_eth_tx_burst()). +It then puts the mbuf back in the cache. + +Ethtool +------- + +Ethtool is a Linux-specific tool with corresponding support in the kernel +where each net device must register its own callbacks for the supported operations. +The current implementation uses the igb/ixgbe modified Linux drivers for ethtool support. +Ethtool is not supported in i40e and VMs (VF or EM devices). + +Link state and MTU change +------------------------- + +Link state and MTU change are network interface specific operations usually done via ifconfig. +The request is initiated from the kernel side (in the context of the ifconfig process) +and handled by the user space DPDK application. +The application polls the request, calls the application handler and returns the response back into the kernel space. + +The application handlers can be registered upon interface creation or explicitly registered/unregistered in runtime. +This provides flexibility in multiprocess scenarios +(where the KNI is created in the primary process but the callbacks are handled in the secondary one). +The constraint is that a single process can register and handle the requests. diff --git

The new bonded PMD will then process these interfaces based on +the mode of operation specified to provide support for features such as +redundant links, fault tolerance and/or load balancing. + +The librte_pmd_bond library exports a C API which provides an API for the +creation of bonded devices as well as the configuration and management of the +bonded device and its slave devices. + +.. note:: + + The Link Bonding PMD Library is enabled by default in the build + configuration files, the library can be disabled by setting + ``CONFIG_RTE_LIBRTE_PMD_BOND=n`` and recompiling the DPDK. + +Link Bonding Modes Overview +--------------------------- + +Currently the Link Bonding PMD library supports following modes of operation: + +* **Round-Robin (Mode 0):** + +.. figure:: img/bond-mode-0.* + + Round-Robin (Mode 0) + + + This mode provides load balancing and fault tolerance by transmission of + packets in sequential order from the first available slave device through + the last. Packets are bulk dequeued from devices then serviced in a + round-robin manner. This mode does not guarantee in order reception of + packets and down stream should be able to handle out of order packets. + +* **Active Backup (Mode 1):** + +.. figure:: img/bond-mode-1.* + + Active Backup (Mode 1) + + + In this mode only one slave in the bond is active at any time, a different + slave becomes active if, and only if, the primary active slave fails, + thereby providing fault tolerance to slave failure. The single logical + bonded interface's MAC address is externally visible on only one NIC (port) + to avoid confusing the network switch. + +* **Balance XOR (Mode 2):** + +.. figure:: img/bond-mode-2.* + + Balance XOR (Mode 2) + + + This mode provides transmit load balancing (based on the selected + transmission policy) and fault tolerance. The default policy (layer2) uses + a simple calculation based on the packet flow source and destination MAC + addresses as well as the number of active slaves available to the bonded + device to classify the packet to a specific slave to transmit on. Alternate + transmission policies supported are layer 2+3, this takes the IP source and + destination addresses into the calculation of the transmit slave port and + the final supported policy is layer 3+4, this uses IP source and + destination addresses as well as the TCP/UDP source and destination port. + +.. note:: + The coloring differences of the packets are used to identify different flow + classification calculated by the selected transmit policy + + +* **Broadcast (Mode 3):** + +.. figure:: img/bond-mode-3.* + + Broadcast (Mode 3) + + + This mode provides fault tolerance by transmission of packets on all slave + ports. + +* **Link Aggregation 802.3AD (Mode 4):** + +.. figure:: img/bond-mode-4.* + + Link Aggregation 802.3AD (Mode 4) + + + This mode provides dynamic link aggregation according to the 802.3ad + specification. It negotiates and monitors aggregation groups that share the + same speed and duplex settings using the selected balance transmit policy + for balancing outgoing traffic. + + DPDK implementation of this mode provide some additional requirements of + the application. + + #. It needs to call ``rte_eth_tx_burst`` and ``rte_eth_rx_burst`` with + intervals period of less than 100ms. + + #. Calls to ``rte_eth_tx_burst`` must have a buffer size of at least 2xN, + where N is the number of slaves. This is a space required for LACP + frames. Additionally LACP packets are included in the statistics, but + they are not returned to the application. + +* **Transmit Load Balancing (Mode 5):** + +.. figure:: img/bond-mode-5.* + + Transmit Load Balancing (Mode 5) + + + This mode provides an adaptive transmit load balancing. It dynamically + changes the transmitting slave, according to the computed load. Statistics + are collected in 100ms intervals and scheduled every 10ms. + + +Implementation Details +---------------------- + +The librte_pmd_bond bonded device are compatible with the Ethernet device API +exported by the Ethernet PMDs described in the *DPDK API Reference*. + +The Link Bonding Library supports the creation of bonded devices at application +startup time during EAL initialization using the ``--vdev`` option as well as +programmatically via the C API ``rte_eth_bond_create`` function. + +Bonded devices support the dynamical addition and removal of slave devices using +the ``rte_eth_bond_slave_add`` / ``rte_eth_bond_slave_remove`` APIs. + +After a slave device is added to a bonded device slave is stopped using +``rte_eth_dev_stop`` and then reconfigured using ``rte_eth_dev_configure`` +the RX and TX queues are also reconfigured using ``rte_eth_tx_queue_setup`` / +``rte_eth_rx_queue_setup`` with the parameters use to configure the bonding +device. If RSS is enabled for bonding device, this mode is also enabled on new +slave and configured as well. + +Setting up multi-queue mode for bonding device to RSS, makes it fully +RSS-capable, so all slaves are synchronized with its configuration. This mode is +intended to provide RSS configuration on slaves transparent for client +application implementation. + +Bonding device stores its own version of RSS settings i.e. RETA, RSS hash +function and RSS key, used to set up its slaves. That let to define the meaning +of RSS configuration of bonding device as desired configuration of whole bonding +(as one unit), without pointing any of slave inside. It is required to ensure +consistency and made it more error-proof. + +RSS hash function set for bonding device, is a maximal set of RSS hash functions +supported by all bonded slaves. RETA size is a GCD of all its RETA's sizes, so +it can be easily used as a pattern providing expected behavior, even if slave +RETAs' sizes are different. If RSS Key is not set for bonded device, it's not +changed on the slaves and default key for device is used. + +All settings are managed through the bonding port API and always are propagated +in one direction (from bonding to slaves). + +Link Status Change Interrupts / Polling +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Link bonding devices support the registration of a link status change callback, +using the ``rte_eth_dev_callback_register`` API, this will be called when the +status of the bonding device changes. For example in the case of a bonding +device which has 3 slaves, the link status will change to up when one slave +becomes active or change to down when all slaves become inactive. There is no +callback notification when a single slave changes state and the previous +conditions are not met. If a user wishes to monitor individual slaves then they +must register callbacks with that slave directly. + +The link bonding library also supports devices which do not implement link +status change interrupts, this is achieved by polling the devices link status at +a defined period which is set using the ``rte_eth_bond_link_monitoring_set`` +API, the default polling interval is 10ms. When a device is added as a slave to +a bonding device it is determined using the ``RTE_PCI_DRV_INTR_LSC`` flag +whether the device supports interrupts or whether the link status should be +monitored by polling it. + +Requirements / Limitations +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The current implementation only supports devices that support the same speed +and duplex to be added as a slaves to the same bonded device. The bonded device +inherits these attributes from the first active slave added to the bonded +device and then all further slaves added to the bonded device must support +these parameters. + +A bonding device must have a minimum of one slave before the bonding device +itself can be started. + +To use a bonding device dynamic RSS configuration feature effectively, it is +also required, that all slaves should be RSS-capable and support, at least one +common hash function available for each of them. Changing RSS key is only +possible, when all slave devices support the same key size. + +To prevent inconsistency on how slaves process packets, once a device is added +to a bonding device, RSS configuration should be managed through the bonding +device API, and not directly on the slave. + +Like all other PMD, all functions exported by a PMD are lock-free functions +that are assumed not to be invoked in parallel on different logical cores to +work on the same target object. + +It should also be noted that the PMD receive function should not be invoked +directly on a slave devices after they have been to a bonded device since +packets read directly from the slave device will no longer be available to the +bonded device to read. + +Configuration +~~~~~~~~~~~~~ + +Link bonding devices are created using the ``rte_eth_bond_create`` API +which requires a unique device name, the bonding mode, +and the socket Id to allocate the bonding device's resources on. +The other configurable parameters for a bonded device are its slave devices, +its primary slave, a user defined MAC address and transmission policy to use if +the device is in balance XOR mode. + +Slave Devices +^^^^^^^^^^^^^ + +Bonding devices support up to a maximum of ``RTE_MAX_ETHPORTS`` slave devices +of the same speed and duplex. Ethernet devices can be added as a slave to a +maximum of one bonded device. Slave devices are reconfigured with the +configuration of the bonded device on being added to a bonded device. + +The bonded also guarantees to return the MAC address of the slave device to its +original value of removal of a slave from it. + +Primary Slave +^^^^^^^^^^^^^ + +The primary slave is used to define the default port to use when a bonded +device is in active backup mode. A different port will only be used if, and +only if, the current primary port goes down. If the user does not specify a +primary port it will default to being the first port added to the bonded device. + +MAC Address +^^^^^^^^^^^ + +The bonded device can be configured with a user specified MAC address, this +address will be inherited by the some/all slave devices depending on the +operating mode. If the device is in active backup mode then only the primary +device will have the user specified MAC, all other slaves will retain their +original MAC address. In mode 0, 2, 3, 4 all slaves devices are configure with +the bonded devices MAC address. + +If a user defined MAC address is not defined then the bonded device will +default to using the primary slaves MAC address. + +Balance XOR Transmit Policies +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +There are 3 supported transmission policies for bonded device running in +Balance XOR mode. Layer 2, Layer 2+3, Layer 3+4. + +* **Layer 2:** Ethernet MAC address based balancing is the default + transmission policy for Balance XOR bonding mode. It uses a simple XOR + calculation on the source MAC address and destination MAC address of the + packet and then calculate the modulus of this value to calculate the slave + device to transmit the packet on. + +* **Layer 2 + 3:** Ethernet MAC address & IP Address based balancing uses a + combination of source/destination MAC addresses and the source/destination + IP addresses of the data packet to decide which slave port the packet will + be transmitted on. + +* **Layer 3 + 4:** IP Address & UDP Port based balancing uses a combination + of source/destination IP Address and the source/destination UDP ports of + the packet of the data packet to decide which slave port the packet will be + transmitted on. + +All these policies support 802.1Q VLAN Ethernet packets, as well as IPv4, IPv6 +and UDP protocols for load balancing. + +Using Link Bonding Devices +-------------------------- + +The librte_pmd_bond library supports two modes of device creation, the libraries +export full C API or using the EAL command line to statically configure link +bonding devices at application startup. Using the EAL option it is possible to +use link bonding functionality transparently without specific knowledge of the +libraries API, this can be used, for example, to add bonding functionality, +such as active backup, to an existing application which has no knowledge of +the link bonding C API. + +Using the Poll Mode Driver from an Application +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Using the librte_pmd_bond libraries API it is possible to dynamically create +and manage link bonding device from within any application. Link bonding +devices are created using the ``rte_eth_bond_create`` API which requires a +unique device name, the link bonding mode to initial the device in and finally +the socket Id which to allocate the devices resources onto. After successful +creation of a bonding device it must be configured using the generic Ethernet +device configure API ``rte_eth_dev_configure`` and then the RX and TX queues +which will be used must be setup using ``rte_eth_tx_queue_setup`` / +``rte_eth_rx_queue_setup``. + +Slave devices can be dynamically added and removed from a link bonding device +using the ``rte_eth_bond_slave_add`` / ``rte_eth_bond_slave_remove`` +APIs but at least one slave device must be added to the link bonding device +before it can be started using ``rte_eth_dev_start``. + +The link status of a bonded device is dictated by that of its slaves, if all +slave device link status are down or if all slaves are removed from the link +bonding device then the link status of the bonding device will go down. + +It is also possible to configure / query the configuration of the control +parameters of a bonded device using the provided APIs +``rte_eth_bond_mode_set/ get``, ``rte_eth_bond_primary_set/get``, +``rte_eth_bond_mac_set/reset`` and ``rte_eth_bond_xmit_policy_set/get``. + +Using Link Bonding Devices from the EAL Command Line +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Link bonding devices can be created at application startup time using the +``--vdev`` EAL command line option. The device name must start with the +net_bonding prefix followed by numbers or letters. The name must be unique for +each device.

As a recommendation, 65536 tbl8s should be sufficient to store +several thousand IPv6 rules, but the number can vary depending on the case. + +An LPM prefix is represented by a pair of parameters (128-bit key, depth), with depth in the range of 1 to 128. +An LPM rule is represented by an LPM prefix and some user data associated with the prefix. +The prefix serves as the unique identifier for the LPM rule. +In this implementation, the user data is 21-bits long and is called "next hop", +which corresponds to its main use of storing the ID of the next hop in a routing table entry. + +The main methods exported for the LPM component are: + +* Add LPM rule: The LPM rule is provided as input. + If there is no rule with the same prefix present in the table, then the new rule is added to the LPM table. + If a rule with the same prefix is already present in the table, the next hop of the rule is updated. + An error is returned when there is no available space left. + +* Delete LPM rule: The prefix of the LPM rule is provided as input. + If a rule with the specified prefix is present in the LPM table, then it is removed. + +* Lookup LPM key: The 128-bit key is provided as input. + The algorithm selects the rule that represents the best match for the given key and returns the next hop of that rule. + In the case that there are multiple rules present in the LPM table that have the same 128-bit value, + the algorithm picks the rule with the highest depth as the best match rule, + which means the rule has the highest number of most significant bits matching between the input key and the rule key. + +Implementation Details +~~~~~~~~~~~~~~~~~~~~~~ + +This is a modification of the algorithm used for IPv4 (see :ref:`lpm4_details`). +In this case, instead of using two levels, one with a tbl24 and a second with a tbl8, 14 levels are used. + +The implementation can be seen as a multi-bit trie where the *stride* +or number of bits inspected on each level varies from level to level. +Specifically, 24 bits are inspected on the root node, and the remaining 104 bits are inspected in groups of 8 bits. +This effectively means that the trie has 14 levels at the most, depending on the rules that are added to the table. + +The algorithm allows the lookup operation to be performed with a number of memory accesses +that directly depends on the length of the rule and +whether there are other rules with bigger depths and the same key in the data structure. +It can vary from 1 to 14 memory accesses, with 5 being the average value for the lengths +that are most commonly used in IPv6. + +The main data structure is built using the following elements: + +* A table with 224 entries + +* A number of tables, configurable by the user through the API, with 28 entries + +The first table, called tbl24, is indexed using the first 24 bits of the IP address be looked up, +while the rest of the tables, called tbl8s, +are indexed using the rest of the bytes of the IP address, in chunks of 8 bits. +This means that depending on the outcome of trying to match the IP address of an incoming packet to the rule stored in the tbl24 +or the subsequent tbl8s we might need to continue the lookup process in deeper levels of the tree. + +Similar to the limitation presented in the algorithm for IPv4, +to store every possible IPv6 rule, we would need a table with 2^128 entries. +This is not feasible due to resource restrictions. + +By splitting the process in different tables/levels and limiting the number of tbl8s, +we can greatly reduce memory consumption while maintaining a very good lookup speed (one memory access per level). + + +.. figure:: img/tbl24_tbl8_tbl8.* + + Table split into different levels + + +An entry in a table contains the following fields: + +* next hop / index to the tbl8 + +* depth of the rule (length) + +* valid flag + +* valid group flag + +* external entry flag + +The first field can either contain a number indicating the tbl8 in which the lookup process should continue +or the next hop itself if the longest prefix match has already been found. +The depth or length of the rule is the number of bits of the rule that is stored in a specific entry. +The flags are used to determine whether the entry/table is valid or not +and whether the search process have finished or not respectively. + +Both types of tables share the same structure. + +The other main data structure is a table containing the main information about the rules (IP, next hop and depth). +This is a higher level table, used for different things: + +* Check whether a rule already exists or not, prior to addition or deletion, + without having to actually perform a lookup. + +When deleting, to check whether there is a rule containing the one that is to be deleted. +This is important, since the main data structure will have to be updated accordingly. + +Addition +~~~~~~~~ + +When adding a rule, there are different possibilities. +If the rule's depth is exactly 24 bits, then: + +* Use the rule (IP address) as an index to the tbl24. + +* If the entry is invalid (i.e. it doesn't already contain a rule) then set its next hop to its value, + the valid flag to 1 (meaning this entry is in use), + and the external entry flag to 0 (meaning the lookup process ends at this point, + since this is the longest prefix that matches). + +If the rule's depth is bigger than 24 bits but a multiple of 8, then: + +* Use the first 24 bits of the rule as an index to the tbl24. + +* If the entry is invalid (i.e. it doesn't already contain a rule) then look for a free tbl8, + set the index to the tbl8 to this value, + the valid flag to 1 (meaning this entry is in use), + and the external entry flag to 1 + (meaning the lookup process must continue since the rule hasn't been explored completely). + +* Use the following 8 bits of the rule as an index to the next tbl8. + +* Repeat the process until the tbl8 at the right level (depending on the depth) has been reached + and fill it with the next hop, setting the next entry flag to 0. + +If the rule's depth is any other value, prefix expansion must be performed. +This means the rule is copied to all the entries (as long as they are not in use) which would also cause a match. + +As a simple example, let's assume the depth is 20 bits. +This means that there are 2^(24-20) = 16 different combinations of the first 24 bits of an IP address that would cause a match. +Hence, in this case, we copy the exact same entry to every position indexed by one of these combinations. + +By doing this we ensure that during the lookup process, if a rule matching the IP address exists, +it is found in, at the most, 14 memory accesses, +depending on how many times we need to move to the next table. +Prefix expansion is one of the keys of this algorithm, since it improves the speed dramatically by adding redundancy. + +Prefix expansion can be performed at any level. +So, for example, is the depth is 34 bits, it

However: + +* Typically, on IPv6, routes are not longer than 48 bits, which means rules usually take up to 3 tbl8s. + +As explained in the LPM for IPv4 algorithm, it is possible and very likely that several rules will share one or more tbl8s, +depending on what their first bytes are. +If they share the same first 24 bits, for instance, the tbl8 at the second level will be shared. +This might happen again in deeper levels, so, effectively, +two 48 bit-long rules may use the same three tbl8s if the only difference is in their last byte. + +The number of tbl8s is a parameter exposed to the user through the API in this version of the algorithm, +due to its impact in memory consumption and the number or rules that can be added to the LPM table. +One tbl8 consumes 1 kilobyte of memory. + +Use Case: IPv6 Forwarding +------------------------- + +The LPM algorithm is used to implement the Classless Inter-Domain Routing (CIDR) strategy used by routers implementing IP forwarding. diff --git a/dpdk/doc/guides/prog_guide/lpm_lib.rst b/dpdk/doc/guides/prog_guide/lpm_lib.rst new file mode 100644 index 0000000..99563a4 --- /dev/null +++ b/dpdk/doc/guides/prog_guide/lpm_lib.rst @@ -0,0 +1,198 @@ +..

(LPM) table search method for 32-bit keys +that is typically used to find the best route match in IP forwarding applications. + +LPM API Overview +---------------- + +The main configuration parameter for LPM component instances is the maximum number of rules to support. +An LPM prefix is represented by a pair of parameters (32- bit key, depth), with depth in the range of 1 to 32. +An LPM rule is represented by an LPM prefix and some user data associated with the prefix. +The prefix serves as the unique identifier of the LPM rule. +In this implementation, the user data is 1-byte long and is called next hop, +in correlation with its main use of storing the ID of the next hop in a routing table entry. + +The main methods exported by the LPM component are: + +* Add LPM rule: The LPM rule is provided as input. + If there is no rule with the same prefix present in the table, then the new rule is added to the LPM table. + If a rule with the same prefix is already present in the table, the next hop of the rule is updated. + An error is returned when there is no available rule space left. + +* Delete LPM rule: The prefix of the LPM rule is provided as input. + If a rule with the specified prefix is present in the LPM table, then it is removed. + +* Lookup LPM key: The 32-bit key is provided as input. + The algorithm selects the rule that represents the best match for the given key and returns the next hop of that rule. + In the case that there are multiple rules present in the LPM table that have the same 32-bit key, + the algorithm picks the rule with the highest depth as the best match rule, + which means that the rule has the highest number of most significant bits matching between the input key and the rule key. + +.. _lpm4_details: + +Implementation Details +---------------------- + +The current implementation uses a variation of the DIR-24-8 algorithm that trades memory usage for improved LPM lookup speed. +The algorithm allows the lookup operation to be performed with typically a single memory read access. +In the statistically rare case when the best match rule is having a depth bigger than 24, +the lookup operation requires two memory read accesses. +Therefore, the performance of the LPM lookup operation is greatly influenced by +whether the specific memory location is present in the processor cache or not. + +The main data structure is built using the following elements: + +* A table with 2^24 entries. + +* A number of tables (RTE_LPM_TBL8_NUM_GROUPS) with 2^8 entries. + +The first table, called tbl24, is indexed using the first 24 bits of the IP address to be looked up, +while the second table(s), called tbl8, is indexed using the last 8 bits of the IP address. +This means that depending on the outcome of trying to match the IP address of an incoming packet to the rule stored in the tbl24 +we might need to continue the lookup process in the second level. + +Since every entry of the tbl24 can potentially point to a tbl8, ideally, we would have 2^24 tbl8s, +which would be the same as having a single table with 2^32 entries. +This is not feasible due to resource restrictions. +Instead, this approach takes advantage of the fact that rules longer than 24 bits are very rare. +By splitting the process in two different tables/levels and limiting the number of tbl8s, +we can greatly reduce memory consumption while maintaining a very good lookup speed (one memory access, most of the times). + + +.. figure:: img/tbl24_tbl8.* + + Table split into different levels + + +An entry in tbl24 contains the following fields: + +* next hop / index to the tbl8 + +* valid flag + +* external entry flag + +* depth of the rule (length) + +The first field can either contain a number indicating the tbl8 in which the lookup process should continue +or the next hop itself if the longest prefix match has already been found. +The two flags are used to determine whether the entry is valid or not and +whether the search process have finished or not respectively. +The depth or length of the rule is the number of bits of the rule that is stored in a specific entry. + +An entry in a tbl8 contains the following fields: + +* next hop + +* valid + +* valid group + +* depth + +Next hop and depth contain the same information as in the tbl24. +The two flags show whether the entry and the table are valid respectively. + +The other main data structure is a table containing the main information about the rules (IP and next hop). +This is a higher level table, used for different things: + +* Check whether a rule already exists or not, prior to addition or deletion, + without having to actually perform a lookup. + +* When deleting, to check whether there is a rule containing the one that is to be deleted. + This is important, since the main data structure will have to be updated accordingly. + +Addition +~~~~~~~~ + +When adding a rule, there are different possibilities. +If the rule's depth is exactly 24 bits, then: + +* Use the rule (IP address) as an index to the tbl24. + +* If the entry is invalid (i.e. it doesn't already contain a rule) then set its next hop to its value, + the valid flag to 1 (meaning this entry is in use), + and the external entry flag to 0 + (meaning the lookup process ends at this point, since this is the longest prefix that matches). + +If the rule's depth is exactly 32 bits, then: + +* Use the first 24 bits of the rule as an index to the tbl24. + +* If the entry is invalid (i.e. it doesn't already contain a rule) then look for a free tbl8, + set the index to the tbl8 to this value, + the valid flag to 1 (meaning this entry is in use), and the external entry flag to 1 + (meaning the lookup process must continue since the rule hasn't been explored completely). + +If the rule's depth is any other value, prefix expansion must be performed. +This means the rule is copied to all the entries (as long as they are not in use) which would also cause a match. + +As a simple example, let's assume the depth is 20 bits. +This means that there are 2^(24 - 20) = 16 different combinations of the first 24 bits of an IP address that +would cause a match. +Hence, in this case, we copy the exact same entry to every position indexed by one of these combinations. + +By doing this we ensure that during the lookup process, if a rule matching the IP address exists, +it is found in either one or two memory accesses, +depending on whether we need to move to the next table or not. +Prefix expansion is one of the keys of this algorithm, +since it improves the speed dramatically by adding redundancy. + +Lookup +~~~~~~ + +The lookup process is much simpler and quicker. In this case: + +* Use the first 24 bits of the IP address as an index to the tbl24. + If the entry is not in use, then it means we don't have a rule matching this IP. + If it is valid and the external entry flag is set to 0, then the next hop is returned. + +* If it is valid and the external entry flag is set to 1, + then we use the tbl8 index to find out the tbl8 to be checked, + and the last 8 bits of the IP address as an index to this table. + Similarly, if the entry is not in use, then we don't have a rule matching this IP address. + If it is valid then the next hop is returned. + +Limitations in the Number of Rules +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +There are different things that limit the number of rules that can be added. +The first one is the maximum number of rules, which is a parameter passed through the API. +Once this number is reached, +it is not possible to add any more rules to the routing table unless one or more are removed. + +The second reason is an intrinsic limitation of the algorithm. +As explained before, to avoid high memory consumption, the number of tbl8s is limited in compilation time +(this value is by default 256). +If we exhaust tbl8s, we won't be able to add any more rules. +How many of them are necessary for a specific routing table is hard to determine in advance. + +A tbl8 is consumed whenever we have a new rule with depth bigger than 24, +and the first 24 bits of this rule are not the same as the first 24 bits of a rule previously added. +If they are, then the new rule will share the same tbl8 than the previous one, +since the only difference between the two rules is within the last byte. + +With the default value of 256, we can have up to 256 rules longer than 24 bits that differ on their first three bytes. +Since routes longer than 24 bits are unlikely, this shouldn't be a problem in most setups. +Even if it is, however, the number of tbl8s can be modified. + +Use Case: IPv4 Forwarding +~~~~~~~~~~~~~~~~~~~~~~~~~ + +The LPM algorithm is used to implement Classless Inter-Domain Routing (CIDR) strategy used by routers implementing IPv4 forwarding. + +References +~~~~~~~~~~ + +* RFC1519 Classless Inter-Domain Routing (CIDR): an Address Assignment and Aggregation Strategy, + `http://www.ietf.org/rfc/rfc1519 `_ + +* Pankaj Gupta, Algorithms for Routing Lookups and Packet Classification, PhD Thesis, Stanford University, + 2000 (`http://klamath.stanford.edu/~pankaj/thesis/ thesis_1sided.pdf `_ ) diff --git a/dpdk/doc/guides/prog_guide/mbuf_lib.rst b/dpdk/doc/guides/prog_guide/mbuf_lib.rst new file mode 100644 index 0000000..210a9af --- /dev/null +++ b/dpdk/doc/guides/prog_guide/mbuf_lib.rst @@ -0,0 +1,253 @@ +..

For the case of a group of sets, the library +will return not only whether the element has been inserted before in one of +the sets but also which set it belongs to. The Membership Library is an +extension and generalization of a traditional filter structure (for example +Bloom Filter [Member-bloom]) that has multiple usages in a wide variety of +workloads and applications. In general, the Membership Library is a data +structure that provides a "set-summary" on whether a member belongs to a set, +and as discussed in detail later, there are two advantages of using such a +set-summary rather than operating on a "full-blown" complete list of elements: +first, it has a much smaller storage requirement than storing the whole list of +elements themselves, and secondly checking an element membership (or other +operations) in this set-summary is much faster than checking it for the +original full-blown complete list of elements. + +We use the term "Set-Summary" in this guide to refer to the space-efficient, +probabilistic membership data structure that is provided by the library. A +membership test for an element will return the set this element belongs to or +that the element is "not-found" with very high probability of accuracy. Set-summary +is a fundamental data aggregation component that can be used in many network +(and other) applications. It is a crucial structure to address performance and +scalability issues of diverse network applications including overlay networks, +data-centric networks, flow table summaries, network statistics and +traffic monitoring. A set-summary is useful for applications who need to +include a list of elements while a complete list requires too much space +and/or too much processing cost. In these situations, the set-summary works as +a lossy hash-based representation of a set of members. It can dramatically +reduce space requirement and significantly improve the performance of set +membership queries at the cost of introducing a very small membership test error +probability. + +.. _figure_membership1: +.. figure:: img/member_i1.* + + Example Usages of Membership Library + +There are various usages for a Membership Library in a very +large set of applications and workloads. Interested readers can refer to +[Member-survey] for a survey of possible networking usages. The above figure +provide a small set of examples of using the Membership Library: + +* Sub-figure (a) + depicts a distributed web cache architecture where a collection of proxies + attempt to share their web caches (cached from a set of back-end web servers) to + provide faster responses to clients, and the proxies use the Membership + Library to share summaries of what web pages/objects they are caching. With the + Membership Library, a proxy receiving an http request will inquire the + set-summary to find its location and quickly determine whether to retrieve the + requested web page from a nearby proxy or from a back-end web server. + +* Sub-figure (b) depicts another example for using the Membership Library to + prevent routing loops which is typically done using slow TTL countdown and + dropping packets when TTL expires. As shown in Sub-figure (b), an embedded + set-summary in the packet header itself can be used to summarize the set of + nodes a packet has gone through, and each node upon receiving a packet can check + whether its id is a member of the set of visited nodes, and if it is, then a + routing loop is detected. + +* Sub-Figure (c) presents another usage of the Membership + Library to load-balance flows to worker threads with in-order guarantee where a + set-summary is used to query if a packet belongs to an existing flow or a new + flow. Packets belonging to a new flow are forwarded to the current least loaded + worker thread, while those belonging to an existing flow are forwarded to the + pre-assigned thread to guarantee in-order processing. + +* Sub-figure (d) highlights + yet another usage example in the database domain where a set-summary is used to + determine joins between sets instead of creating a join by comparing each + element of a set against the other elements in a different set, a join is done + on the summaries since they can efficiently encode members of a given set. + +Membership Library is a configurable library that is optimized to cover set +membership functionality for both a single set and multi-set scenarios. Two set-summary +schemes are presented including (a) vector of Bloom Filters and (b) Hash-Table based +set-summary schemes with and without false negative probability. +This guide first briefly describes these different types of set-summaries, usage examples for each, +and then it highlights the Membership Library API. + +Vector of Bloom Filters +----------------------- + +Bloom Filter (BF) [Member-bloom] is a well-known space-efficient +probabilistic data structure that answers set membership queries (test whether +an element is a member of a set) with some probability of false positives and +zero false negatives; a query for an element returns either it is "possibly in +a set" (with very high probability) or "definitely not in a set". + +The BF is a method for representing a set of ``n`` elements (for example flow keys +in network applications domain) to support membership queries. The idea of BF is +to allocate a bit-vector ``v`` with ``m`` bits, which are initially all set to 0. Then +it chooses ``k`` independent hash functions ``h1``, ``h2``, ... ``hk`` with hash values range from +``0`` to ``m-1`` to perform hashing calculations on each element to be inserted. Every time when an +element ``X`` being inserted into the set, the bits at positions ``h1(X)``, ``h2(X)``, ... +``hk(X)`` in ``v`` are set to 1 (any particular bit might be set to 1 multiple times +for multiple different inserted elements). Given a query for any element ``Y``, the +bits at positions ``h1(Y)``, ``h2(Y)``, ... ``hk(Y)`` are checked. If any of them is 0, +then Y is definitely not in the set. Otherwise there is a high probability that +Y is a member of the set with certain false positive probability. As shown in +the next equation, the false positive probability can be made arbitrarily small +by changing the number of hash functions (``k``) and the vector length (``m``). + +.. _figure_membership2: +.. figure:: img/member_i2.* + + Bloom Filter False Positive Probability + +Without BF, an accurate membership testing could involve a costly hash table +lookup and full element comparison. The advantage of using a BF is to simplify +the membership test into a series of hash calculations and memory accesses for a +small bit-vector, which can be easily optimized. Hence the lookup throughput +(set membership test) can be significantly faster than a normal hash table +lookup with element comparison. + +.. _figure_membership3: +.. figure:: img/member_i3.* + + Detecting Routing Loops Using BF + +BF is used for applications that need only one set, and the +membership of elements is checked against the BF. The example discussed +in the above figure is one example of potential applications that uses only one +set to capture the node IDs that have been visited so far by the packet. Each +node will then check this embedded BF in the packet header for its own id, and +if the BF indicates that the current node is definitely not in the set then a +loop-free route is guaranteed. + + +.. _figure_membership4: +.. figure:: img/member_i4.* + + Vector Bloom Filter (vBF) Overview + +To support membership test for both multiple sets and a single set, +the library implements a Vector Bloom Filter (vBF) scheme. +vBF basically composes multiple bloom filters into a vector of bloom filers. +The membership test is conducted on all of the +bloom filters concurrently to determine which set(s) it belongs to or none of +them. The basic idea of vBF is shown in the above figure where an element is +used to address multiple bloom filters concurrently and the bloom filter +index(es) with a hit is returned. + +.. _figure_membership5: +.. figure:: img/member_i5.* + + vBF for Flow Scheduling to Worker Thread + +As previously mentioned, there are many usages of such structures. vBF is used +for applications that need to check membership against multiple sets +simultaneously. The example shown in the above figure uses a set to capture +all flows being assigned for processing at a given worker thread. Upon receiving +a packet the vBF is used to quickly figure out if this packet belongs to a new flow +so as to be forwarded to the current least loaded worker thread, or otherwise it +should be queued for an existing thread to guarantee in-order processing (i.e. +the property of vBF to indicate right away that a given flow is a new one or +not is critical to minimize response time latency). + +It should be noted that vBF can be implemented using a set of single bloom +filters with sequential lookup of each BF. However, being able to concurrently +search all set-summaries is a big throughput advantage. In the library, certain +parallelism is realized by the implementation of checking all bloom filters +together. + + +Hash-Table based Set-Summaries +------------------------------ + +Hash-table based set-summary (HTSS) is another scheme in the membership library. +Cuckoo filter [Member-cfilter] is an example of HTSS. +HTSS supports multi-set membership testing like +vBF does. However, while vBF is better for a small number of targets, HTSS is more suitable +and can easily outperform vBF when the number of sets is +large, since HTSS uses a single hash table for membership testing while vBF +requires testing a series of Bloom Filters each corresponding to one set. +As a result, generally speaking vBF is more adequate for the case of a small limited number of sets +while HTSS should be used with a larger number of sets. + +.. _figure_membership6: +.. figure:: img/member_i6.* + + Using HTSS for Attack Signature Matching + +As shown in the above figure, attack signature matching where each set +represents a certain signature length (for correctness of this example, an +attack signature should not be a subset of another one) in the payload is a good +example for using HTSS with 0% false negative (i.e., when an element returns not +found, it has a 100% certainty that it is not a member of any set). The packet +inspection application benefits from knowing right away that the current payload +does not match any attack signatures in the database to establish its +legitimacy, otherwise a deep inspection of the packet is needed. + +HTSS employs a similar but simpler data structure to a traditional hash table, +and the major difference is that HTSS stores only the signatures but not the +full keys/elements which can significantly reduce the footprint of the table. +Along with the signature, HTSS also stores a value to indicate the target set. +When looking up an element, the element is hashed and the HTSS is addressed +to retrieve the signature stored. If the signature matches then the value is +retrieved corresponding to the index of the target set which the element belongs +to. Because signatures can collide, HTSS can still has false positive +probability. Furthermore, if elements are allowed to be +overwritten or evicted when the hash table becomes full, it will also have a +false negative probability. We discuss this case in the next section. + +Set-Summaries with False Negative Probability +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +As previously mentioned, traditional set-summaries (e.g. Bloom Filters) do not +have a false negative probability, i.e., it is 100% certain when an element +returns "not to be present" for a given set. However, the Membership Library +also supports a set-summary probabilistic data structure based on HTSS which +allows for false negative probability. + +In HTSS, when the hash table becomes full, keys/elements will fail to be added +into the table and the hash table has to be resized to accommodate for these new +elements, which can be expensive. However, if we allow new elements to overwrite +or evict existing elements (as a cache typically does), then the resulting +set-summary will begin to have false negative probability. This is because the +element that was evicted from the set-summary may still be present in the target +set. For subsequent inquiries the set-summary will falsely report the element +not being in the set, hence having a false negative probability. + +The major usage of HTSS with false negative is to use it as a cache for +distributing elements to different target sets. By allowing HTSS to evict old +elements, the set-summary can keep track of the most recent elements +(i.e. active) as a cache typically does. Old inactive elements (infrequently +used elements) will automatically and eventually get evicted from the +set-summary. It is worth noting that the set-summary still has false positive +probability, which means the application either can tolerate certain false positive +or it has fall-back path when false positive happens. + +.. _figure_membership7: +.. figure:: img/member_i7.* + + Using HTSS with False Negatives for Wild Card Classification + +HTSS with false negative (i.e. a cache) also has its wide set of applications. +For example wild card flow classification (e.g. ACL rules) highlighted in the +above figure is an example of such application. In that case each target set +represents a sub-table with rules defined by a certain flow mask. The flow masks +are non-overlapping, and for flows matching more than one rule only the highest +priority one is inserted in the corresponding sub-table (interested readers can +refer to the Open vSwitch (OvS) design of Mega Flow Cache (MFC) [Member-OvS] +for further details). Typically the rules will have a large number of distinct +unique masks and hence, a large number of target sets each corresponding to one +mask. Because the active set of flows varies widely based on the network +traffic, HTSS with false negative will act as a cache for pair for the current active set of flows. When a miss occurs (as +shown in red in the above figure) the sub-tables will be searched sequentially +one by one for a possible match, and when found the flow key and target +sub-table will be inserted into the set-summary (i.e. cache insertion) so +subsequent packets from the same flow don’t incur the overhead of the +sequential search of sub-tables. + +Library API Overview +-------------------- + +The design goal of the Membership Library API is to be as generic as possible to +support all the different types of set-summaries we discussed in previous +sections and beyond. Fundamentally, the APIs need to include creation, +insertion, deletion, and lookup. + + +Set-summary Create +~~~~~~~~~~~~~~~~~~ + +The ``rte_member_create()`` function is used to create a set-summary structure, the input parameter +is a struct to pass in parameters that needed to initialize the set-summary, while the function returns the +pointer to the created set-summary or ``NULL`` if the creation failed. + +The general input arguments used when creating the set-summary should include ``name`` +which is the name of the created set-summary, *type* which is one of the types +supported by the library (e.g. ``RTE_MEMBER_TYPE_HT`` for HTSS or ``RTE_MEMBER_TYPE_VBF`` for vBF), and ``key_len`` +which is the length of the element/key. There are other parameters +are only used for certain type of set-summary, or which have a slightly different meaning for different types of set-summary. +For example, ``num_keys`` parameter means the maximum number of entries for Hash table based set-summary. +However, for bloom filter, this value means the expected number of keys that could be +inserted into the bloom filter(s). The value is used to calculate the size of each +bloom filter. + +We also pass two seeds: ``prim_hash_seed`` and +``sec_hash_seed`` for the primary and secondary hash functions to calculate two independent hash values. +``socket_id`` parameter is the NUMA socket ID for the memory used to create the +set-summary. For HTSS, another parameter ``is_cache`` is used to indicate +if this set-summary is a cache (i.e. with false negative probability) or not. +For vBF, extra parameters are needed. For example, ``num_set`` is the number of +sets needed to initialize the vector bloom filters. This number is equal to the +number of bloom filters will be created. +``false_pos_rate`` is the false positive rate. num_keys and false_pos_rate will be used to determine +the number of hash functions and the bloom filter size. + + +Set-summary Element Insertion +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The ``rte_member_add()`` function is used to insert an element/key into a set-summary structure. If it fails an +error is returned. For success the returned value is dependent on the +set-summary mode to provide extra information for the users. For vBF +mode, a return value of 0 means a successful insert. For HTSS mode without false negative, the insert +could fail with ``-ENOSPC`` if the table is full. With false negative (i.e. cache mode), +for insert that does not cause any eviction (i.e. no overwriting happens to an +existing entry) the return value is 0. For insertion that causes eviction, the return +value is 1 to indicate such situation, but it is not an error. + +The input arguments for the function should include the ``key`` which is a pointer to the element/key that needs to +be added to the set-summary, and ``set_id`` which is the set id associated +with the key that needs to be added. + + +Set-summary Element Lookup +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The ``rte_member_lookup()`` function looks up a single key/element in the set-summary structure. It +returns as soon as the first match is found. The return value is 1 if a +match is found and 0 otherwise. The arguments for the function include ``key`` which is a pointer to the +element/key that needs to be looked up, and ``set_id`` which is used to return the +first target set id where the key has matched, if any. + +The ``rte_member_lookup_bulk()`` function is used to look up a bulk of keys/elements in the +set-summary structure for their first match. Each key lookup returns as soon as the first match is found. The +return value is the number of keys that find a match. The arguments of the function include ``keys`` +which is a pointer to a bulk of keys that are to be looked up, +``num_keys`` is the number +of keys that will be looked up, and ``set_ids`` are the return target set +ids for the first match found for each of the input keys. ``set_ids`` is an array +needs to be sized according to the ``num_keys``. If there is no match, the set id +for that key will be set to RTE_MEMBER_NO_MATCH. + +The ``rte_member_lookup_multi()`` function looks up a single key/element in the +set-summary structure for multiple matches. It +returns ALL the matches (possibly more than one) found for this key when it +is matched against all target sets (it is worth noting that for cache mode HTSS, +the current implementation matches at most one target set). The return value is +the number of matches +that was found for this key (for cache mode HTSS the return value +should be at most 1). The arguments for the function include ``key`` which is a pointer to the +element/key that needs to be looked up, ``max_match_per_key`` which is to indicate the maximum number of matches +the user expects to find for each key, and ``set_id`` which is used to return all +target set ids where the key has matched, if any. The ``set_id`` array should be sized +according to ``max_match_per_key``. For vBF, the maximum number of matches per key is equal +to the number of sets. For HTSS, the maximum number of matches per key is equal to two time +entry count per bucket. ``max_match_per_key`` should be equal or smaller than the maximum number of +possible matches. + +The ``rte_membership_lookup_multi_bulk()`` function looks up a bulk of keys/elements in the +set-summary structure for multiple matches, each key lookup returns ALL the matches (possibly more +than one) found for this key when it is matched against all target sets (cache mode HTSS +matches at most one target set). The +return value is the number of keys that find one or more matches in the +set-summary structure. The arguments of the +function include ``keys`` which is +a pointer to a bulk of keys that are to be looked up, ``num_keys`` is the number +of keys that will be looked up, ``max_match_per_key`` is the possible +maximum number of matches for each key, ``match_count`` which is the returned number +of matches for each key, and ``set_ids`` are the returned target set +ids for all matches found for each keys. ``set_ids`` is 2-D array +containing a 1-D array for each key (the size of 1-D array per key should be set by the user according to ``max_match_per_key``). +``max_match_per_key`` should be equal or smaller than the maximum number of +possible matches, similar to ``rte_member_lookup_multi``. + + +Set-summary Element Delete +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The ``rte_membership_delete()`` function deletes an element/key from a set-summary structure, if it fails +an error is returned. The input arguments should include ``key`` which is a pointer to the +element/key that needs to be deleted from the set-summary, and ``set_id`` +which is the set id associated with the key to delete. It is worth noting that current +implementation of vBF does not support deletion [1]_. An error code ``-EINVAL`` will be returned. + +..

loaded. + +This is particularly true for packet buffers when doing L3 forwarding or flow classification. +Only the first 64 bytes are accessed, so performance can be increased by spreading the start

compare-and-set (CAS) operation. +To avoid having too many access requests to the memory pool's ring, +the memory pool allocator can maintain a per-core cache and do bulk requests to the memory pool's ring, +via the cache with many fewer locks on the actual memory pool structure. +In this way, each core has full access to its own cache (with locks) of free objects and +only when the cache fills does the core need to shuffle some of the free objects back to the pools ring or +obtain more objects when the cache is empty. + +While this may mean a number of buffers may sit idle on some core's cache, +the speed at which a core can access its own cache for a specific memory pool without locks provides performance gains. + +The cache is composed of a small, per-core table of pointers and its length (used as a stack). +This internal cache can be enabled or disabled at creation of the pool. + +The maximum size of the cache is static and is defined at compilation time (CONFIG_RTE_MEMPOOL_CACHE_MAX_SIZE). + +:numref:`figure_mempool` shows a cache in operation. + +.. _figure_mempool: + +.. figure:: img/mempool.* + + A mempool in Memory with its Associated Ring + +Alternatively to the internal default per-lcore local cache, an application can create and manage external caches through the ``rte_mempool_cache_create()``, ``rte_mempool_cache_free()`` and

Address-Space Layout Randomization (ASLR) can interfere with this mapping, + so it may be necessary to disable this feature in order to reliably run multi-process applications. + +.. warning:: + + Disabling Address-Space Layout Randomization (ASLR) may have security implications, + so it is recommended that it be disabled only when absolutely necessary, + and only when the implications of this change have been understood. + +* All DPDK processes running as a single application and using shared memory must have distinct coremask/corelist arguments. + It is not possible to have a primary and secondary instance, or two secondary instances, + using any of the same logical cores. + Attempting to do so can cause corruption of memory pool caches, among other issues. + +* The delivery of interrupts, such as Ethernet* device link status interrupts, do not work in secondary processes. + All interrupts are triggered inside the primary process only. + Any application needing interrupt notification in multiple processes should provide its own mechanism + to transfer the interrupt information from the primary process to any secondary process that needs the information. + +* The use of function pointers between multiple processes running based of different compiled binaries is not supported, + since the location of a given function in one process may be different to its location in a second. + This prevents the librte_hash library from behaving properly as in a multi-threaded instance, + since it uses a pointer to the hash function internally. + +To work around this issue, it is recommended that multi-process applications perform the hash calculations by directly calling +the hashing function from the code and then using the rte_hash_add_with_hash()/rte_hash_lookup_with_hash() functions +instead of the functions which do the hashing internally, such as rte_hash_add()/rte_hash_lookup(). + +* Depending upon the hardware in use, and the number of DPDK processes used, + it may not be possible to have HPET timers available in each DPDK instance. + The minimum number of HPET comparators available to Linux* userspace can be just a single comparator, + which means that only the first, primary DPDK process instance can open and mmap /dev/hpet. + If the number of required DPDK processes exceeds that of the number of available HPET comparators, + the TSC (which is the default timer in this release) must be used as a time source across all processes instead of the HPET. diff --git a/dpdk/doc/guides/prog_guide/overview.rst b/dpdk/doc/guides/prog_guide/overview.rst new file mode 100644 index 0000000..2663fe0 --- /dev/null +++ b/dpdk/doc/guides/prog_guide/overview.rst @@ -0,0 +1,170 @@ +..

Requires SSE 4.1 support. + +* **RTE_ACL_CLASSIFY_AVX2**: vector implementation, can process up to 16 flows in parallel. Requires AVX2 support. + +It is purely a runtime decision which method to choose, there is no build-time difference. +All implementations operates over the same internal RT structures and use similar principles. The main difference is that vector implementations can manually exploit IA SIMD instructions and process several input data flows in parallel. +At startup ACL library determines the highest available classify method for the given platform and sets it as default one. Though the user has an ability to override the default classifier function for a given ACL context or perform particular search using non-default classify method. In that case it is user responsibility to make sure that given platform supports selected classify implementation. + +Application Programming Interface (API) Usage +--------------------------------------------- + +.. note:: + + For more details about the Access Control API, please refer to the *DPDK API Reference*. + +The following example demonstrates IPv4, 5-tuple classification for rules defined above +with multiple categories in more detail. + +Classify with Multiple Categories +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +.. code-block:: c + + struct rte_acl_ctx * acx; + struct rte_acl_config cfg; + int ret; + + /* define a structure for the rule with up to 5 fields. */ + + RTE_ACL_RULE_DEF(acl_ipv4_rule, RTE_DIM(ipv4_defs)); + + /* AC context creation parameters. */ + + struct rte_acl_param prm = { + .name = "ACL_example", + .socket_id = SOCKET_ID_ANY, + .rule_size = RTE_ACL_RULE_SZ(RTE_DIM(ipv4_defs)), + + /* number of fields per rule. */ + + .max_rule_num = 8, /* maximum number of rules in the AC context. */ + }; + + struct acl_ipv4_rule acl_rules[] = { + + /* matches all packets traveling to 192.168.0.0/16, applies for categories: 0,1 */ + { + .data = {.userdata = 1, .category_mask = 3, .priority = 1}, + + /* destination IPv4 */ + .field[2] = {.value.u32 = IPv4(192,168,0,0),. mask_range.u32 = 16,}, + + /* source port */ + .field[3] = {.value.u16 = 0, .mask_range.u16 = 0xffff,}, + + /* destination port */ + .field[4] = {.value.u16 = 0, .mask_range.u16 = 0xffff,}, + }, + + /* matches all packets traveling to 192.168.1.0/24, applies for categories: 0 */ + { + .data = {.userdata = 2, .category_mask = 1, .priority = 2}, + + /* destination IPv4 */ + .field[2] = {.value.u32 = IPv4(192,168,1,0),. mask_range.u32 = 24,}, + + /* source port */ + .field[3] = {.value.u16 = 0, .mask_range.u16 = 0xffff,}, + + /* destination port */ + .field[4] = {.value.u16 = 0, .mask_range.u16 = 0xffff,}, + }, + + /* matches all packets traveling from 10.1.1.1, applies for categories: 1 */ + { + .data = {.userdata = 3, .category_mask = 2, .priority = 3}, + + /* source IPv4 */ + .field[1] = {.value.u32 = IPv4(10,1,1,1),. mask_range.u32 = 32,}, + + /* source port */ + .field[3] = {.value.u16 = 0, .mask_range.u16 = 0xffff,}, + + /* destination port */ + .field[4] = {.value.u16 = 0, .mask_range.u16 = 0xffff,}, + }, + + }; + + + /* create an empty AC context */ + + if ((acx = rte_acl_create(&prm)) == NULL) { + + /* handle context create failure. */ + + } + + /* add rules to the context */ + + ret = rte_acl_add_rules(acx, acl_rules, RTE_DIM(acl_rules)); + if (ret != 0) { + /* handle error at adding ACL rules. */ + } + + /* prepare AC build config. */ + + cfg.num_categories = 2; + cfg.num_fields = RTE_DIM(ipv4_defs); + + memcpy(cfg.defs, ipv4_defs, sizeof (ipv4_defs)); + + /* build the runtime structures for added rules, with 2 categories. */ + + ret = rte_acl_build(acx, &cfg); + if (ret != 0) { + /* handle error at build runtime structures for ACL context. */ + } + +For a tuple with source IP address: 10.1.1.1 and destination IP address: 192.168.1.15, +once the following lines are executed: + +.. code-block:: c + + uint32_t results[4]; /* make classify for 4 categories. */ + + rte_acl_classify(acx, data, results, 1, 4); + +then the results[] array contains: + +.. code-block:: c + + results[4] = {2, 3, 0, 0}; + +* For category 0, both rules 1 and 2 match, but rule 2 has higher priority, + therefore results[0] contains the userdata for rule 2. + +* For category 1, both rules 1 and 3 match, but rule 3 has higher priority, + therefore results[1] contains the userdata for rule 3. + +* For categories 2 and 3, there are no matches, so results[2] and results[3] contain zero, + which indicates that no matches were found for those categories. + +For a tuple with source IP address: 192.168.1.1 and destination IP address: 192.168.2.11, +once the following lines are executed: + +.. code-block:: c + + uint32_t results[4]; /* make classify by 4 categories. */ + + rte_acl_classify(acx, data, results, 1, 4); + +the results[] array contains: + +.. code-block:: c + + results[4] = {1, 1, 0, 0}; + +* For categories 0 and 1, only rule 1 matches. + +* For categories 2 and 3, there are no matches. + +For a tuple with source IP address: 10.1.1.1 and destination IP address: 201.212.111.12, +once the following lines are executed: + +.. code-block:: c + + uint32_t results[4]; /* make classify by 4 categories. */ + rte_acl_classify(acx, data, results, 1, 4); + +the results[] array contains: + +.. code-block:: c + + results[4] = {0, 3, 0, 0}; + +* For category 1, only rule 3 matches. + +* For categories 0, 2 and 3, there are no matches. diff --git a/dpdk/doc/guides/prog_guide/packet_distrib_lib.rst b/dpdk/doc/guides/prog_guide/packet_distrib_lib.rst new file mode 100644 index 0000000..3c3b746 --- /dev/null +++ b/dpdk/doc/guides/prog_guide/packet_distrib_lib.rst @@ -0,0 +1,94 @@ +..

Packets are passed to the distributor component by having the distributor lcore thread call the "rte_distributor_process()" API + +#. The worker lcores all share a single cache line with the distributor core in order to pass messages and packets to and from the worker. + The process API call will poll all the worker cache lines to see what workers are requesting packets. + +#. As workers request packets, the distributor takes packets from the set of packets passed in and distributes them to the workers. + As it does so, it examines the "tag" -- stored in the RSS hash field in the mbuf -- for each packet + and records what tags are being processed by each worker. + +#. If the next packet in the input set has a tag which is already being processed by a worker, + then that packet will be queued up for processing by that worker + and given to it in preference to other packets when that work next makes a request for work. + This ensures that no two packets with the same tag are processed in parallel, + and that all packets with the same tag are processed in input order. + +#. Once all input packets passed to the process API have either been distributed to workers + or been queued up for a worker which is processing a given tag, + then the process API returns to the caller. + +Other functions which are available to the distributor lcore are: + +* rte_distributor_returned_pkts() + +* rte_distributor_flush() + +* rte_distributor_clear_returns() + +Of these the most important API call is "rte_distributor_returned_pkts()" +which should only be called on the lcore which also calls the process API. +It returns to the caller all packets which have finished processing by all worker cores. +Within this set of returned packets, all packets sharing the same tag will be returned in their original order. + +**NOTE:** +If worker lcores buffer up packets internally for transmission in bulk afterwards, +the packets sharing a tag will likely get out of order. +Once a worker lcore requests a new packet, the distributor assumes that it has completely finished with the previous packet and +therefore that additional packets with the same tag can safely be distributed to other workers -- +who may then flush their buffered packets sooner and cause packets to get out of order. + +**NOTE:** +No packet ordering guarantees are made about packets which do not share a common packet tag. + +Using the process and returned_pkts API, the following application workflow can be used, +while allowing packet order within a packet flow -- identified by a tag -- to be maintained. + + +.. figure:: img/packet_distributor2.* + + Application workflow + + +The flush and clear_returns API calls, mentioned previously, +are likely of less use that the process and returned_pkts APIS, and are principally provided to aid in unit testing of the library. +Descriptions of these functions and their use can be found in the DPDK API Reference document. + +Worker Operation +---------------- + +Worker cores are the cores which do the actual manipulation of the packets distributed by the packet distributor. +Each worker calls "rte_distributor_get_pkt()" API to request a new packet when it has finished processing the previous one. +[The previous packet should be returned to the distributor component by passing it as the final parameter to this API call.] + +Since it may be desirable to vary the number of worker cores, depending on the traffic load +i.e. to save power at times of lighter load, +it is possible to have a worker stop processing packets by calling "rte_distributor_return_pkt()" to indicate that +it has finished the current packet and does not want a new one. diff --git a/dpdk/doc/guides/prog_guide/packet_framework.rst b/dpdk/doc/guides/prog_guide/packet_framework.rst new file mode 100644 index 0000000..f0b4856 --- /dev/null +++ b/dpdk/doc/guides/prog_guide/packet_framework.rst @@ -0,0 +1,1141 @@ +..

preconfigured for lookup | + | | | miss. | + | | | | + +---+-----------------+----------------------------------------------------------------------------------------+ + + +Hash Table Design +~~~~~~~~~~~~~~~~~ + +Hash Table Overview +^^^^^^^^^^^^^^^^^^^ + +Hash tables are important because the key lookup operation is optimized for speed: +instead of having to linearly search the lookup key through all the keys in the table, +the search is limited to only the keys stored in a single table bucket. + +**Associative Arrays** + +An associative array is a function that can be specified as a set of (key, value) pairs, +with each key from the possible set of input keys present at most once. +For a given associative array, the possible operations are: + +#. *add (key, value)*: When no value is currently associated with *key*, then the (key, *value* ) association is created. + When *key* is already associated value *value0*, then the association (*key*, *value0*) is removed + and association *(key, value)* is created; + +#. *delete key*: When no value is currently associated with *key*, this operation has no effect. + When *key* is already associated *value*, then association *(key, value)* is removed; + +#. *lookup key*: When no value is currently associated with *key*, then this operation returns void value (lookup miss). + When *key* is associated with *value*, then this operation returns *value*. + The *(key, value)* association is not changed. + +The matching criterion used to compare the input key against the keys in the associative array is *exact match*, +as the key size (number of bytes) and the key value (array of bytes) have to match exactly for the two keys under comparison. + +**Hash Function** + +A hash function deterministically maps data of variable length (key) to data of fixed size (hash value or key signature). +Typically, the size of the key is bigger than the size of the key signature. +The hash function basically compresses a long key into a short signature. +Several keys can share the same signature (collisions). + +High quality hash functions have uniform distribution. +For large number of keys, when dividing the space of signature values into a fixed number of equal intervals (buckets), +it is desirable to have the key signatures evenly distributed across these intervals (uniform distribution), +as opposed to most of the signatures going into only a few of the intervals +and the rest of the intervals being largely unused (non-uniform distribution). + +**Hash Table** + +A hash table is an associative array that uses a hash function for its operation. +The reason for using a hash function is to optimize the performance of the lookup operation +by minimizing the number of table keys that have to be compared against the input key. + +Instead of storing the (key, value) pairs in a single list, the hash table maintains multiple lists (buckets). +For any given key, there is a single bucket where that key might exist, and this bucket is uniquely identified based on the key signature. +Once the key signature is computed and the hash table bucket identified, +the key is either located in this bucket or it is not present in the hash table at all, +so the key search can be narrowed down from the full set of keys currently in the table +to just the set of keys currently in the identified table bucket. + +The performance of the hash table lookup operation is greatly improved, +provided that the table keys are evenly distributed among the hash table buckets, +which can be achieved by using a hash function with uniform distribution. +The rule to map a key to its bucket can simply be to use the key signature (modulo the number of table buckets) as the table bucket ID: + + *bucket_id = f_hash(key) % n_buckets;* + +By selecting the number of buckets to be a power of two, the modulo operator can be replaced by a bitwise AND logical operation: + + *bucket_id = f_hash(key) & (n_buckets - 1);* + +considering *n_bits* as the number of bits set in *bucket_mask = n_buckets - 1*, +this means that all the keys that end up in the same hash table bucket have the lower *n_bits* of their signature identical. +In order to reduce the number of keys in the same bucket (collisions), the number of hash table buckets needs to be increased. + +In packet processing context, the sequence of operations involved in hash table operations is described in :numref:`figure_figure33`: + +.. _figure_figure33: + +.. figure:: img/figure33.* + + Sequence of Steps for Hash Table Operations in a Packet Processing Context + + + +Hash Table Use Cases +^^^^^^^^^^^^^^^^^^^^ + +**Flow Classification** + +*Description:* The flow classification is executed at least once for each input packet. +This operation maps each incoming packet against one of the known traffic flows in the flow database that typically contains millions of flows. + +*Hash table name:* Flow classification table + +*Number of keys:* Millions + +*Key format:* n-tuple of packet fields that uniquely identify a traffic flow/connection. +Example: DiffServ 5-tuple of (Source IP address, Destination IP address, L4 protocol, L4 protocol source port, L4 protocol destination port). +For IPv4 protocol and L4 protocols like TCP, UDP or SCTP, the size of the DiffServ 5-tuple is 13 bytes, while for IPv6 it is 37 bytes. + +*Key value (key data):* actions and action meta-data describing what processing to be applied for the packets of the current flow. +The size of the data associated with each traffic flow can vary from 8 bytes to kilobytes. + +**Address Resolution Protocol (ARP)** + +*Description:* Once a route has been identified for an IP packet (so the output interface and the IP address of the next hop station are known), +the MAC address of the next hop station is needed in order to send this packet onto the next leg of the journey +towards its destination (as identified by its destination IP address). +The MAC address of the next hop station becomes the destination MAC address of the outgoing Ethernet frame. + +*Hash table name:* ARP table + +*Number of keys:* Thousands + +*Key format:* The pair of (Output interface, Next Hop IP address), which is typically 5 bytes for IPv4 and 17 bytes for IPv6. + +*Key value (key data):* MAC address of the next hop station (6 bytes). + +Hash Table Types

The logic to pick the key to be dropped from the bucket is LRU. + The hash table lookup operation maintains the order in which the keys in the same bucket are hit, so every time a key is hit, + it becomes the new Most Recently Used (MRU) key, i.e. the last candidate for drop. + When a key is added to the bucket, it also becomes the new MRU key. + When a key needs to be picked and dropped, the first candidate for drop, i.e. the current LRU key, is always picked. + The LRU logic requires maintaining specific data structures per each bucket. + +#. **Extendable Bucket Hash Table.** + The bucket is extended with space for 4 more keys. + This is done by allocating additional memory at table initialization time, + which is used to create a pool of free keys (the size of this pool is

configurable key size.** + +#. **Implementation supporting a single key size.** + Typical key sizes are 8 bytes and 16 bytes. + +Bucket Search Logic for Configurable Key Size Hash Tables +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The performance of the bucket search logic is one of the main factors influencing the performance of the key lookup operation. +The data structures and algorithm are designed to make the best use of Intel CPU architecture resources like: +cache memory space, cache memory bandwidth, external memory bandwidth, multiple execution units working in parallel, +out of order instruction execution, special CPU instructions, etc. + +The bucket search logic handles multiple input packets in parallel. +It is built as a pipeline of several stages (3 or 4), with each pipeline stage handling two different packets from the burst of input packets. +On each pipeline iteration, the packets are pushed to the next pipeline stage: for the 4-stage pipeline, +two packets (that just completed stage 3) exit the pipeline, +two packets (that just completed stage 2) are now executing stage 3, two packets (that just completed stage 1) are now executing stage 2, +two packets (that just completed stage 0) are now executing stage 1 and two packets (next two packets to read from the burst of input packets) +are entering the pipeline to execute stage 0. +The pipeline iterations continue until all packets from the burst of input packets execute the last stage of the pipeline. + +The bucket search logic is broken into pipeline stages at the boundary of the next memory access. +Each pipeline stage uses data structures that are stored (with high probability) into the L1 or L2 cache memory of the current CPU core and +breaks just before the next memory access required by the algorithm. +The current pipeline stage finalizes by prefetching the data structures required by the next pipeline stage, +so given enough time for the prefetch to complete, +when the next pipeline stage eventually gets executed for the same packets, +it will read the data structures it needs from L1 or L2 cache memory and thus avoid the significant penalty incurred by L2 or L3 cache memory miss. + +By prefetching the data structures required by the next pipeline stage in advance (before they are used) +and switching to executing another pipeline stage for different packets, +the number of L2 or L3 cache memory misses is greatly reduced, hence one of the main reasons for improved performance. +This is because the cost of L2/L3 cache memory miss on memory read accesses is high, as usually due to data dependency between instructions, +the CPU execution units have to stall until the read operation is completed from L3 cache memory or external DRAM memory. +By using prefetch instructions, the latency of memory read accesses is hidden, +provided that it is preformed early enough before the respective data structure is actually used. + +By splitting the processing into several stages that are executed on different packets (the packets from the input burst are interlaced), +enough work is created to allow the prefetch instructions to complete successfully (before the prefetched data structures are actually accessed) and +also the data dependency between instructions is loosened. +For example, for the 4-stage pipeline, stage 0 is executed on packets 0 and 1 and then, +before same packets 0 and 1 are used (i.e. before stage 1 is executed on packets 0 and 1), +different packets are used: packets 2 and 3 (executing stage 1), packets 4 and 5 (executing stage 2) and packets 6 and 7 (executing stage 3). +By executing useful work while the data structures are brought into the L1 or L2 cache memory, the latency of the read memory accesses is hidden. +By increasing the gap between two consecutive accesses to the same data structure, the data dependency between instructions is loosened; +this allows making the best use of the super-scalar and out-of-order execution CPU architecture, +as the number of CPU core execution units that are active (rather than idle or stalled due to data dependency constraints between instructions) is maximized. + +The bucket search logic is also implemented without using any branch instructions. +This avoids the important cost associated with flushing the CPU core execution pipeline on every instance of branch misprediction. + +Configurable Key Size Hash Table +"""""""""""""""""""""""""""""""" + +:numref:`figure_figure34`, :numref:`table_qos_25` and

duration is application specific), +for data consistency reasons, no other threads (threads performing table lookup or entry add/delete operations) are allowed to modify this table entry. + +Mechanisms to share the same table between multiple threads: + +#. **Multiple writer threads.** + Threads need to use synchronization primitives like semaphores (distinct semaphore per table entry) or atomic instructions. + The cost of semaphores is usually high, even when the semaphore is free. + The cost of atomic instructions is normally higher than the cost of regular instructions. + +#. **Multiple writer threads, with single thread performing table lookup operations and multiple threads performing table entry add/delete operations.** + The threads performing table entry add/delete operations send table update requests to the reader (typically through message passing queues), + which does the actual table updates and then sends the response back to the request initiator. + +#. **Single writer thread performing table entry add/delete operations and multiple reader threads that perform table lookup operations with read-only access to the table entries.** + The reader threads use the main table copy while the writer is updating the mirror copy. + Once the writer update is done, the writer can signal to the readers and busy wait until all readers swaps between the mirror copy (which now becomes the main copy) and + the mirror copy (which now becomes the main copy). + +Interfacing with Accelerators +----------------------------- + +The presence of accelerators is usually detected during the initialization phase by inspecting the HW devices that are part of the system (e.g. by PCI bus enumeration). +Typical devices with acceleration capabilities are: + +* Inline accelerators: NICs, switches, FPGAs, etc; + +* Look-aside accelerators: chipsets, FPGAs, etc. + +Usually, to support a specific functional block, specific implementation of Packet Framework tables and/or ports and/or actions has to be provided for each accelerator, +with all the implementations sharing the same API: pure SW implementation (no acceleration), implementation using accelerator A, implementation using accelerator B, etc. +The selection between these implementations could be done at build time or at run-time (recommended), based on which accelerators are present in the system, +with no application changes required. diff --git a/dpdk/doc/guides/prog_guide/pdump_lib.rst b/dpdk/doc/guides/prog_guide/pdump_lib.rst new file mode 100644 index 0000000..ed3c15e --- /dev/null +++ b/dpdk/doc/guides/prog_guide/pdump_lib.rst @@ -0,0 +1,96 @@ +..

Gigabit and para virtualized virtio Poll Mode Drivers. + +A Poll Mode Driver (PMD) consists of APIs, provided through the BSD driver running in user space, +to configure the devices and their respective queues. +In addition, a PMD accesses the RX and TX descriptors directly without any interrupts +(with the exception of Link Status Change interrupts) to quickly receive, +process and deliver packets in the user's application. +This section describes the requirements of the PMDs, +their global design principles and proposes a high-level architecture and a generic external API for the Ethernet PMDs. + +Requirements and Assumptions +---------------------------- + +The DPDK environment for packet processing applications allows for two models, run-to-completion and pipe-line: + +* In the *run-to-completion* model, a specific port's RX descriptor ring is polled for packets through an API. + Packets are then processed on the same core and placed on a port's TX descriptor ring through an API for transmission. + +* In the *pipe-line* model, one core polls one or more port's RX descriptor ring through an API. + Packets are received and passed to another core via a ring. + The other core continues to process the packet which then may be placed on a port's TX descriptor ring through an API for transmission. + +In a synchronous run-to-completion model, +each logical core assigned to the DPDK executes a packet processing loop that includes the following steps: + +* Retrieve input packets through the PMD receive API + +* Process each received packet one at a time, up to its forwarding + +* Send pending output packets through the PMD transmit API + +Conversely, in an asynchronous pipe-line model, some logical cores may be dedicated to the retrieval of received packets and +other logical cores to the processing of previously received packets. +Received packets are exchanged between logical cores through rings. +The loop for packet retrieval includes the following steps: + +* Retrieve input packets through the PMD receive API + +* Provide received packets to processing lcores through packet queues + +The loop for packet processing includes the following steps: + +* Retrieve the received packet from the packet queue + +* Process the received packet, up to its retransmission if forwarded + +To avoid any unnecessary interrupt processing overhead, the execution environment must not use any asynchronous notification mechanisms. +Whenever needed and appropriate, asynchronous communication should be introduced as much as possible through the use of rings. + +Avoiding lock contention is a key issue in a multi-core environment. +To address this issue, PMDs are designed to work with per-core private resources as much as possible. +For example, a PMD maintains a separate transmit queue per-core, per-port, if the PMD is not ``DEV_TX_OFFLOAD_MT_LOCKFREE`` capable. +In the same way, every receive queue of a port is assigned to and polled by a single logical core (lcore). + +To comply with Non-Uniform Memory Access (NUMA), memory management is designed to assign to each logical core +a private buffer pool in local memory to minimize remote memory access. +The configuration of packet buffer pools should take into account the underlying physical memory architecture in terms of DIMMS, +channels and ranks. +The application must ensure that appropriate parameters are given at memory pool creation time. +See :ref:`Mempool Library `. + +Design Principles +----------------- + +The API and architecture of the Ethernet* PMDs are designed with the following guidelines in mind. + +PMDs must help global policy-oriented decisions to be enforced at the upper application level. +Conversely, NIC PMD functions should not impede the benefits expected by upper-level global policies, +or worse prevent such policies from being applied. + +For instance, both the receive and transmit functions of a PMD have a maximum number of packets/descriptors to poll. +This allows a run-to-completion processing stack to statically fix or +to dynamically adapt its overall behavior through different global loop policies, such as: + +* Receive, process immediately and transmit packets one at a time in a piecemeal fashion. + +* Receive as many packets as possible, then process all received packets, transmitting them immediately. + +* Receive a given maximum number of packets, process the received packets, accumulate them and finally send all accumulated packets to transmit. + +To achieve optimal performance, overall software design choices and pure software optimization techniques must be considered and +balanced against available low-level hardware-based optimization features (CPU cache properties, bus speed, NIC PCI bandwidth, and so on). +The case of packet transmission is an example of this software/hardware tradeoff issue when optimizing burst-oriented network packet processing engines. +In the initial case, the PMD could export only an rte_eth_tx_one function to transmit one packet at a time on a given queue. +On top of that, one can easily build an rte_eth_tx_burst function that loops invoking the rte_eth_tx_one function to transmit several packets at a time. +However, an rte_eth_tx_burst function is effectively implemented by the PMD to minimize the driver-level transmit cost per packet through the following optimizations: + +* Share among multiple packets the un-amortized cost of invoking the rte_eth_tx_one function. + +* Enable the rte_eth_tx_burst function to take advantage of burst-oriented hardware features (prefetch data in cache, use of NIC head/tail registers) + to minimize the number of CPU cycles per packet, for example by avoiding unnecessary read memory accesses to ring transmit descriptors, + or by systematically using arrays of pointers that exactly fit cache line boundaries and sizes. + +* Apply burst-oriented software optimization techniques to remove operations that would otherwise be unavoidable, such as ring index wrap back management. + +Burst-oriented functions are also introduced via the API for services that are intensively used by the PMD. +This applies in particular to buffer allocators used to populate NIC rings, which provide functions to allocate/free several buffers at a time. +For example, an mbuf_multiple_alloc function returning an array of pointers to rte_mbuf buffers which speeds up the receive poll function of the PMD when +replenishing multiple descriptors of the receive ring. + +Logical Cores, Memory and NIC Queues Relationships +-------------------------------------------------- + +The DPDK supports NUMA allowing for better performance when a processor's logical cores and interfaces utilize its local memory. +Therefore, mbuf allocation associated with local PCIe* interfaces should be allocated from memory pools created in the local memory. +The buffers should, if possible, remain on the local processor to obtain the best performance results and RX and TX buffer descriptors +should be populated with mbufs allocated from a mempool allocated from local memory. + +The run-to-completion model also performs better if packet or data manipulation is in local memory instead of a remote processors memory. +This is also true for the pipe-line model provided all logical cores used are located on the same processor. + +Multiple logical cores should never share receive or transmit queues for interfaces since this would require global locks and hinder performance. + +If the PMD is ``DEV_TX_OFFLOAD_MT_LOCKFREE`` capable, multiple threads can invoke ``rte_eth_tx_burst()`` +concurrently on the same tx queue without SW lock. This PMD feature found in some NICs and useful in the following use cases: + +* Remove explicit spinlock in some applications where lcores are not mapped to Tx queues with 1:1 relation. + +* In the eventdev use case, avoid dedicating a separate TX core for transmitting and thus + enables more scaling as all workers can send the packets. + +See `Hardware Offload`_ for ``DEV_TX_OFFLOAD_MT_LOCKFREE`` capability probing details. + +Device Identification, Ownership and Configuration +-------------------------------------------------- + +Device Identification +~~~~~~~~~~~~~~~~~~~~~ + +Each NIC port is uniquely designated by its (bus/bridge, device, function) PCI +identifiers assigned by the PCI probing/enumeration function executed at DPDK initialization. +Based on their PCI identifier, NIC ports are assigned two other identifiers: + +* A port index used to designate the NIC port in all functions exported by the PMD API. + +* A port name used to designate the port in console messages, for administration or debugging purposes. + For ease of use, the port name includes the port index. + +Port Ownership +~~~~~~~~~~~~~~ +The Ethernet devices ports can be owned by a single DPDK entity (application, library, PMD, process, etc). +The ownership mechanism is controlled by ethdev APIs and allows to set/remove/get a port owner by DPDK entities. +Allowing this should prevent any multiple management of Ethernet port by different entities. + +.. note:: + + It is the DPDK entity responsibility to set the port owner before using it and to manage the port usage synchronization between different threads or processes. + +Device Configuration +~~~~~~~~~~~~~~~~~~~~ + +The configuration of each NIC port includes the following operations: + +* Allocate PCI resources + +* Reset the hardware (issue a Global Reset) to a well-known default state + +* Set up the PHY and the link + +* Initialize statistics counters + +The PMD API must also export functions to start/stop the all-multicast feature of a port and functions to set/unset the port in promiscuous mode. + +Some hardware offload features must be individually configured at port initialization through specific configuration parameters. +This is the case for the Receive Side Scaling (RSS) and Data Center Bridging (DCB) features for example. + +On-the-Fly Configuration +~~~~~~~~~~~~~~~~~~~~~~~~ + +All device features that can be started or stopped "on the fly" (that is, without stopping the device) do not require the PMD API to export dedicated functions for this purpose. + +All that is required is the mapping address of the device PCI registers to implement the configuration of these features in specific functions outside of the drivers. + +For this purpose, +the PMD API exports a function that provides all the information associated with a device that can be used to set up a given device feature outside of the driver. +This includes the PCI vendor identifier, the PCI device identifier, the mapping address of the PCI device registers, and the name of the driver. + +The main advantage of this approach is that it gives complete freedom on the choice of the API used to configure, to start, and to stop such features. + +As an example, refer to the configuration of the IEEE1588 feature for the Intel® 82576 Gigabit Ethernet Controller and +the Intel® 82599 10 Gigabit Ethernet Controller controllers in the testpmd application. + +Other features such as the L3/L4 5-Tuple packet filtering feature of a port can be configured in the same way. +Ethernet* flow control (pause frame) can be configured on the individual port. +Refer to the testpmd source code for details. +Also, L4 (UDP/TCP/ SCTP) checksum offload by the NIC can be enabled for an individual packet as long as the packet mbuf is set up correctly. See `Hardware Offload`_ for details. + +Configuration of Transmit Queues +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Each transmit queue is independently configured with the following information: + +* The number of descriptors of the transmit ring + +* The socket identifier used to identify the appropriate DMA memory zone from which to allocate the transmit ring in NUMA architectures + +* The values of the Prefetch, Host and Write-Back threshold registers of the transmit queue + +* The *minimum* transmit packets to free threshold (tx_free_thresh). + When the number of descriptors used to transmit packets exceeds this threshold, the network adaptor should be checked to see if it has written back descriptors. + A value of 0 can be passed during the TX queue configuration to indicate the default value should be used. + The default value for tx_free_thresh is 32. + This ensures that the PMD does not search for completed descriptors until at least 32 have been processed by the NIC for this queue. + +* The *minimum* RS bit threshold. The minimum number of transmit descriptors to use before setting the Report Status (RS) bit in the transmit descriptor. + Note that this parameter may only be valid for Intel 10 GbE network adapters. + The RS bit is set on the last descriptor used to transmit a packet if the number of descriptors used since the last RS bit setting, + up to the first descriptor used to transmit the packet, exceeds the transmit RS bit threshold (tx_rs_thresh). + In short, this parameter controls which transmit descriptors are written back to host memory by the network adapter. + A value of 0 can be passed during the TX queue configuration to indicate that the default value should be used. + The default value for tx_rs_thresh is 32. + This ensures that at least 32 descriptors are used before the network adapter writes back the most recently used descriptor. + This saves upstream PCIe* bandwidth resulting from TX descriptor write-backs. + It is important to note that the TX Write-back threshold (TX wthresh) should be set to 0 when tx_rs_thresh is greater than 1. + Refer to the Intel® 82599 10 Gigabit Ethernet Controller Datasheet for more details. + +The following constraints must be satisfied for tx_free_thresh and tx_rs_thresh: + +* tx_rs_thresh must be greater than 0. + +* tx_rs_thresh must be less than the size of the ring minus 2. + +* tx_rs_thresh must be less than or equal to tx_free_thresh. + +* tx_free_thresh must be greater than 0. + +* tx_free_thresh must be less than the size of the ring minus 3. + +* For optimal performance, TX wthresh should be set to 0 when tx_rs_thresh is greater than 1. + +One descriptor in the TX ring is used as a sentinel to avoid a hardware race condition, hence the maximum threshold constraints. + +.. note:: + + When configuring for DCB operation, at port initialization, both the number of transmit queues and the number of receive queues must be set to 128. + +Free Tx mbuf on Demand +~~~~~~~~~~~~~~~~~~~~~~ + +Many of the drivers do not release the mbuf back to the mempool, or local cache, +immediately after the packet has been transmitted. +Instead, they leave the mbuf in their Tx ring and +either perform a bulk release when the ``tx_rs_thresh`` has been crossed +or free the mbuf when a slot in the Tx ring is needed. + +An application can request the driver to release used mbufs with the ``rte_eth_tx_done_cleanup()`` API. +This API requests the driver to release mbufs that are no longer in use, +independent of whether or not the ``tx_rs_thresh`` has been crossed. +There are two scenarios when an application may want the mbuf released immediately: + +* When a given packet needs to be sent to multiple destination interfaces + (either for Layer 2 flooding or Layer 3 multi-cast). + One option is to make a copy of the packet or a copy of the header portion that needs to be manipulated. + A second option is to transmit the packet and then poll the ``rte_eth_tx_done_cleanup()`` API + until the reference count on the packet is decremented. + Then the same packet can be transmitted to the next destination interface. + The application is still responsible for managing any packet manipulations needed + between the different destination interfaces, but a packet copy can be avoided. + This API is independent of whether the packet was transmitted or dropped, + only that the mbuf is no longer in use by the interface. + +* Some applications are designed to make multiple runs, like a packet generator. + For performance reasons and consistency between runs, + the application may want to reset back to an initial state + between each run, where all mbufs are returned to the mempool. + In this case, it can call the ``rte_eth_tx_done_cleanup()`` API + for each destination interface it has been using + to request it to release of all its used mbufs. + +To determine if a driver supports this API, check for the *Free Tx mbuf on demand* feature +in the *Network Interface Controller Drivers* document. + +Hardware Offload +~~~~~~~~~~~~~~~~ + +Depending on driver capabilities advertised by +``rte_eth_dev_info_get()``, the PMD may support hardware offloading +feature like checksumming, TCP segmentation, VLAN insertion or +lockfree multithreaded TX burst on the same TX queue. + +The support of these offload features implies the addition of dedicated +status bit(s) and value field(s) into the rte_mbuf data structure, along +with their appropriate handling by the receive/transmit functions +exported by each PMD. The list of flags and their precise meaning is +described in the mbuf API documentation and in the in :ref:`Mbuf Library +`, section "Meta Information". + +Per-Port and Per-Queue Offloads +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +In the DPDK offload API, offloads are divided into per-port and per-queue offloads. +The different offloads capabilities can be queried using ``rte_eth_dev_info_get()``. +Supported offloads can be either per-port or per-queue. + +Offloads are enabled using the existing ``DEV_TX_OFFLOAD_*`` or ``DEV_RX_OFFLOAD_*`` flags. +Per-port offload configuration is set using ``rte_eth_dev_configure``. +Per-queue offload configuration is set using ``rte_eth_rx_queue_setup`` and ``rte_eth_tx_queue_setup``. +To enable per-port offload, the offload should be set on both device configuration and queue setup. +In case of a mixed configuration the queue setup shall return with an error. +To enable per-queue offload, the offload can be set only on the queue setup. +Offloads which are not enabled are disabled by default. + +For an application to use the Tx offloads API it should set the ``ETH_TXQ_FLAGS_IGNORE`` flag in the ``txq_flags`` field located in ``rte_eth_txconf`` struct. +In such cases it is not required to set other flags in ``txq_flags``. +For an application to use the Rx offloads API it should set the ``ignore_offload_bitfield`` bit in the ``rte_eth_rxmode`` struct. +In such cases it is not required to set other bitfield offloads in the ``rxmode`` struct. + +Poll Mode Driver API +-------------------- + +Generalities +~~~~~~~~~~~~ + +By default, all functions exported by a PMD are lock-free functions that are assumed +not to be invoked in parallel on different logical cores to work on the same target object. +For instance, a PMD receive function cannot be invoked in parallel on two logical cores to poll the same RX queue of the same port. +Of course, this function can be invoked in parallel by different logical cores on different RX queues. +It is the responsibility of the upper-level application to enforce this rule. + +If needed, parallel accesses by multiple logical cores to shared queues can be explicitly protected by dedicated inline lock-aware functions +built on top of their corresponding lock-free functions of the PMD API. + +Generic Packet Representation +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +A packet is represented by an rte_mbuf structure, which is a generic metadata structure containing all necessary housekeeping information. +This includes fields and status bits corresponding to offload hardware features, such as checksum computation of IP headers or VLAN tags. + +The rte_mbuf data structure includes specific fields to represent, in a generic way, the offload features provided by network controllers. +For an input packet, most fields of the rte_mbuf structure are filled in by the PMD receive function with the information contained in the receive descriptor. +Conversely, for output packets, most fields of rte_mbuf structures are used by the PMD transmit function to initialize transmit descriptors. + +The mbuf structure is fully described in the :ref:`Mbuf Library ` chapter. + +Ethernet Device API +~~~~~~~~~~~~~~~~~~~ + +The Ethernet device API exported by the Ethernet PMDs is described in the *DPDK API Reference*. + +Extended Statistics API +~~~~~~~~~~~~~~~~~~~~~~~ + +The extended statistics API allows a PMD to expose all statistics that are +available to it, including statistics that are unique to the device. +Each statistic has three properties ``name``, ``id`` and ``value``: + +* ``name``: A human readable string formatted by the scheme detailed below. +* ``id``: An integer that represents only that statistic. +* ``value``: A unsigned 64-bit integer that is the value of the statistic. + +Note that extended statistic identifiers are +driver-specific, and hence might not be the same for different ports. +The API consists of various ``rte_eth_xstats_*()`` functions, and allows an +application to be flexible in how it retrieves statistics. + +Scheme for Human Readable Names +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +A naming scheme exists for the strings exposed to clients of the API. This is +to allow scraping of the API for statistics of interest. The naming scheme uses +strings split by a single underscore ``_``. The scheme is as follows: + +* direction +* detail 1 +* detail 2 +* detail n +* unit + +Examples of common statistics xstats strings, formatted to comply to the scheme +proposed above: + +* ``rx_bytes`` +* ``rx_crc_errors`` +* ``tx_multicast_packets`` + +The scheme, although quite simple, allows flexibility in presenting and reading +information from the statistic strings. The following example illustrates the +naming scheme:``rx_packets``. In this example, the string is split into two +components. The first component ``rx`` indicates that the statistic is +associated with the receive side of the NIC. The second component ``packets`` +indicates that the unit of measure is packets. + +A more complicated example: ``tx_size_128_to_255_packets``. In this example, +``tx`` indicates transmission, ``size`` is the first detail, ``128`` etc are +more details, and ``packets`` indicates that this is a packet counter. + +Some additions in the metadata scheme are as follows: + +* If the first part does not match ``rx`` or ``tx``, the statistic does not + have an affinity with either receive of transmit. + +* If the first letter of the second part is ``q`` and this ``q`` is followed + by a number, this statistic is part of a specific queue. + +An example where queue numbers are used is as follows: ``tx_q7_bytes`` which +indicates this statistic applies to queue number 7, and represents the number +of transmitted bytes on that queue. + +API Design +^^^^^^^^^^ + +The xstats API uses the ``name``, ``id``, and ``value`` to allow performant +lookup of specific statistics. Performant lookup means two things; + +* No string comparisons with the ``name`` of the statistic in fast-path +* Allow requesting of only the statistics of interest + +The API ensures these requirements are met by mapping the ``name`` of the +statistic to a unique ``id``, which is used as a key for lookup in the fast-path. +The API allows applications to request an array of ``id`` values, so that the +PMD only performs the required calculations. Expected usage is that the +application scans the ``name`` of each statistic, and caches the ``id`` +if it has an interest in that statistic. On the fast-path, the integer can be used +to retrieve the actual ``value`` of the statistic that the ``id`` represents. + +API Functions +^^^^^^^^^^^^^ + +The API is built out of a small number of functions, which can be used to +retrieve the number of statistics and the names, IDs and values of those +statistics. + +* ``rte_eth_xstats_get_names_by_id()``: returns the names of the statistics. When given a + ``NULL`` parameter the function returns the number of statistics that are available. + +* ``rte_eth_xstats_get_id_by_name()``: Searches for the statistic ID that matches + ``xstat_name``. If found, the ``id`` integer is set. + +* ``rte_eth_xstats_get_by_id()``: Fills in an array of ``uint64_t`` values + with matching the provided ``ids`` array. If the ``ids`` array is NULL, it + returns all statistics that are available. + + +Application Usage +^^^^^^^^^^^^^^^^^ + +Imagine an application that wants to view the dropped packet count. If no +packets are dropped, the application does not read any other metrics for +performance reasons. If packets are dropped, the application has a particular +set of statistics that it requests. This "set" of statistics allows the app to +decide what next steps to perform. The following code-snippets show how the +xstats API can be used to achieve this goal. + +First step is to get all statistics names and list them: + +.. code-block:: c + + struct rte_eth_xstat_name *xstats_names; + uint64_t *values; + int len, i; + + /* Get number of stats */ + len = rte_eth_xstats_get_names_by_id(port_id, NULL, NULL, 0); + if (len < 0) { + printf("Cannot get xstats count\n"); + goto err; + } + + xstats_names = malloc(sizeof(struct rte_eth_xstat_name) * len); + if (xstats_names == NULL) { + printf("Cannot allocate memory for xstat names\n"); + goto err; + } + + /* Retrieve xstats names, passing NULL for IDs to return all statistics */ + if (len != rte_eth_xstats_get_names_by_id(port_id, xstats_names, NULL, len)) { + printf("Cannot get xstat names\n"); + goto err; + } + + values = malloc(sizeof(values) * len); + if (values == NULL) { + printf("Cannot allocate memory for xstats\n"); + goto err; + } + + /* Getting xstats values */ + if (len != rte_eth_xstats_get_by_id(port_id, NULL, values, len)) { + printf("Cannot get xstat values\n"); + goto err; + } + + /* Print all xstats names and values */ + for (i = 0; i < len; i++) { + printf("%s: %"PRIu64"\n", xstats_names[i].name, values[i]); + } + +The application has access to the names of all of the statistics that the PMD +exposes. The application can decide which statistics are of interest, cache the +ids of those statistics by looking up the name as follows: + +.. code-block:: c + + uint64_t id; + uint64_t value; + const char *xstat_name = "rx_errors"; + + if(!rte_eth_xstats_get_id_by_name(port_id, xstat_name, &id)) { + rte_eth_xstats_get_by_id(port_id, &id, &value, 1); + printf("%s: %"PRIu64"\n", xstat_name, value); + } + else { + printf("Cannot find xstats with a given name\n"); + goto err; + } + +The API provides flexibility to the application so that it can look up multiple +statistics using an array containing multiple ``id`` numbers. This reduces the +function call overhead of retrieving statistics, and makes lookup of multiple +statistics simpler for the application. + +.. code-block:: c + + #define APP_NUM_STATS 4 + /* application cached these ids previously; see above */ + uint64_t ids_array[APP_NUM_STATS] = {3,4,7,21}; + uint64_t value_array[APP_NUM_STATS]; + + /* Getting multiple xstats values from array of IDs */ + rte_eth_xstats_get_by_id(port_id, ids_array, value_array, APP_NUM_STATS); + + uint32_t i; + for(i = 0; i < APP_NUM_STATS; i++) { + printf("%d: %"PRIu64"\n", ids_array[i], value_array[i]); + } + + +This array lookup API for xstats allows the application create multiple +"groups" of statistics, and look up the values of those IDs using a single API +call. As an end result, the application is able to achieve its goal of +monitoring a single statistic ("rx_errors" in this case), and if that shows +packets being dropped, it can easily retrieve a "set" of statistics using the +IDs array parameter to ``rte_eth_xstats_get_by_id`` function. + +NIC Reset API +~~~~~~~~~~~~~ + +.. code-block:: c + + int rte_eth_dev_reset(uint16_t port_id); + +Sometimes a port has to be reset passively. For example when a PF is +reset, all its VFs should also be reset by the application to make them +consistent with the PF. A DPDK application also can call this function +to trigger a port reset. Normally, a DPDK application would invokes this +function when an RTE_ETH_EVENT_INTR_RESET event is detected. + +It is the duty of the PMD to trigger RTE_ETH_EVENT_INTR_RESET events and +the application should register a callback function to handle these +events. When a PMD needs to trigger a reset, it can trigger an +RTE_ETH_EVENT_INTR_RESET event. On receiving an RTE_ETH_EVENT_INTR_RESET +event, applications can handle it as follows: Stop working queues, stop +calling Rx and Tx functions, and then call rte_eth_dev_reset(). For +thread safety all these operations should be called from the same thread. + +For example when PF is reset, the PF sends a message to notify VFs of +this event and also trigger an interrupt to VFs. Then in the interrupt +service routine the VFs detects this notification message and calls +_rte_eth_dev_callback_process(dev, RTE_ETH_EVENT_INTR_RESET, NULL). +This means that a PF reset triggers an RTE_ETH_EVENT_INTR_RESET +event within VFs. The function _rte_eth_dev_callback_process() will +call the registered callback function. The callback function can trigger +the application to handle all operations the VF reset requires including +stopping Rx/Tx queues and calling rte_eth_dev_reset(). + +The rte_eth_dev_reset() itself is a generic function which only does +some hardware reset operations through calling dev_unint() and +dev_init(), and itself does not handle synchronization, which is handled +by application. + +The PMD itself should not call rte_eth_dev_reset(). The PMD can trigger +the application to handle reset event. It is duty of application to +handle all synchronization before it calls rte_eth_dev_reset(). diff --git a/dpdk/doc/guides/prog_guide/port_hotplug_framework.rst b/dpdk/doc/guides/prog_guide/port_hotplug_framework.rst new file mode 100644 index 0000000..fb0efc1 --- /dev/null +++ b/dpdk/doc/guides/prog_guide/port_hotplug_framework.rst @@ -0,0 +1,106 @@ +..

Because the framework depends on PMD +implementation, the ports that PMDs cannot handle are out of scope of this +framework. Furthermore, after detaching a port from a DPDK application, the +framework doesn't provide a way for removing the devices from the system. +For the ports backed by a physical NIC, the kernel will need to support PCI +Hotplug feature. + +Overview +-------- + +The basic requirements of the Port Hotplug Framework are: + +* DPDK applications that use the Port Hotplug Framework must manage their + own ports. + + The Port Hotplug Framework is implemented to allow DPDK applications to + manage ports. For example, when DPDK applications call the port attach + function, the attached port number is returned. DPDK applications can + also detach the port by port number. + +* Kernel support is needed for attaching or detaching physical device + ports. + + To attach new physical device ports, the device will be recognized by + userspace driver I/O framework in kernel at first. Then DPDK + applications can call the Port Hotplug functions to attach the ports. + For detaching, steps are vice versa. + +* Before detaching, they must be stopped and closed. + + DPDK applications must call "rte_eth_dev_stop()" and + "rte_eth_dev_close()" APIs before detaching ports. These functions will + start finalization sequence of the PMDs. + +* The framework doesn't affect legacy DPDK applications behavior. + + If the Port Hotplug functions aren't called, all legacy DPDK apps can + still work without modifications. + +Port Hotplug API overview +------------------------- + +* Attaching a port + + "rte_eth_dev_attach()" API attaches a port to DPDK application, and + returns the attached port number. Before calling the API, the device + should be recognized by an userspace driver I/O framework. The API + receives a pci address like "0000:01:00.0" or a virtual device name + like "net_pcap0,iface=eth0".

BSD is not supported. + +* Not all PMDs support detaching feature. + The underlying bus must support hot-unplug.

Running different physical ports on different threads. The enqueue and dequeue of the same port are run by the same thread. + +#. Splitting the same physical port to different threads by running different sets of subports of the same physical port (virtual ports) on different threads. + Similarly, a subport can be split into multiple subports that are each run by a different thread. + The enqueue and dequeue of the same port are run by the same thread. + This is only required if, for performance reasons, it is not possible to handle a full port with a single core. + +Enqueue and Dequeue for the Same Output Port +"""""""""""""""""""""""""""""""""""""""""""" + +Running enqueue and dequeue operations for the same output port from different cores is likely to cause significant impact on scheduler's performance +and it is therefore not recommended. + +The port enqueue and dequeue operations share access to the following data structures: + +#. Packet descriptors + +#. Queue table + +#. Queue storage area + +#. Bitmap of active queues + +The expected drop in performance is due to: + +#. Need to make the queue and bitmap operations thread safe, + which requires either using locking primitives for access serialization (for example, spinlocks/ semaphores) or + using atomic primitives for lockless access (for example, Test and Set, Compare And Swap, an so on). + The impact is much higher in the former case. + +#. Ping-pong of cache lines storing the shared data structures between the cache hierarchies of the two cores + (done transparently by the MESI protocol cache coherency CPU hardware). + +Therefore, the scheduler enqueue and dequeue operations have to be run from the same thread, +which allows the queues and the bitmap operations to be non-thread safe and +keeps the scheduler data structures internal to the same core. + +Performance Scaling +""""""""""""""""""" + +Scaling up the number of NIC ports simply requires a proportional increase in the number of CPU cores to be used for traffic scheduling. + +Enqueue Pipeline +^^^^^^^^^^^^^^^^ + +The sequence of steps per packet: + +#. *Access* the mbuf to read the data fields required to identify the destination queue for the packet. + These fields are: port, subport, traffic class and queue within traffic class, and are typically set by the classification stage. + +#. *Access* the queue structure to identify the write location in the queue array. + If the queue is full, then the packet is discarded. + +#. *Access* the queue array location to store the packet (i.e. write the mbuf pointer). + +It should be noted the strong data dependency between these steps, as steps 2 and 3 cannot start before the result from steps 1 and 2 becomes available, +which prevents the processor out of order execution engine to provide any significant performance optimizations. + +Given the high rate of input packets and the large amount of queues, +it is expected that the data structures accessed to enqueue the current packet are not present +in the L1 or L2 data cache of the current core, thus the above 3 memory accesses would result (on average) in L1 and L2 data cache misses. +A number of 3 L1/L2 cache misses per packet is not acceptable for performance reasons. + +The workaround is to prefetch the required data structures in advance. The prefetch operation has an execution latency during which +the processor should not attempt to access the data structure currently under prefetch, so the processor should execute other work. +The only other work available is to execute different stages of the enqueue sequence of operations on other input packets, +thus resulting in a pipelined implementation for the enqueue operation. + +:numref:`figure_prefetch_pipeline` illustrates a pipelined implementation for the enqueue operation with 4 pipeline stages and each stage executing 2 different input packets. +No input packet can be part of more than one pipeline stage at a given time. + +.. _figure_prefetch_pipeline: + +.. figure:: img/prefetch_pipeline.* + + Prefetch Pipeline for the Hierarchical Scheduler Enqueue Operation + + +The congestion management scheme implemented by the enqueue pipeline described above is very basic: +packets are enqueued until a specific queue becomes full, +then all the packets destined to the same queue are dropped until packets are consumed (by the dequeue operation). +This can be improved by enabling RED/WRED as part of the enqueue pipeline which looks at the queue occupancy and +packet priority in order to yield the enqueue/drop decision for a specific packet +(as opposed to enqueuing all packets / dropping all packets indiscriminately). + +Dequeue State Machine +^^^^^^^^^^^^^^^^^^^^^ + +The sequence of steps to schedule the next packet from the current pipe is: + +#. Identify the next active pipe using the bitmap scan operation, *prefetch* pipe. + +#. *Read* pipe data structure. Update the credits for the current pipe and its subport. + Identify the first active traffic class within the current pipe, select the next queue using WRR, + *prefetch* queue pointers for all the 16 queues of the current pipe. + +#. *Read* next element from the current WRR queue and *prefetch* its packet descriptor. + +#. *Read* the packet length from the packet descriptor (mbuf structure). + Based on the packet length and the available credits (of current pipe, pipe traffic class, subport and subport traffic class), + take the go/no go scheduling decision for the current packet. + +To avoid the cache misses, the above data structures (pipe, queue, queue array, mbufs) are prefetched in advance of being accessed. +The strategy of hiding the latency of the prefetch operations is to switch from the current pipe (in grinder A) to another pipe +(in grinder B) immediately after a prefetch is issued for the current pipe. +This gives enough time to the prefetch operation to complete before the execution switches back to this pipe (in grinder A). + +The dequeue pipe state machine exploits the data presence into the processor cache, +therefore it tries to send as many packets from the same pipe TC and pipe as possible (up to the available packets and credits) before +moving to the next active TC from the same pipe (if any) or to another active pipe. + +.. _figure_pipe_prefetch_sm: + +.. figure:: img/pipe_prefetch_sm.* + + Pipe Prefetch State Machine for the Hierarchical Scheduler Dequeue + Operation + + +Timing and Synchronization +^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The output port is modeled as a conveyor belt of byte slots that need to be filled by the scheduler with data for transmission. +For 10 GbE, there are 1.25 billion byte slots that need to be filled by the port scheduler every second. +If the scheduler is not fast enough to fill the slots, provided that enough packets and credits exist, +then some slots will be left unused and bandwidth will be wasted. + +In principle, the hierarchical scheduler dequeue operation should be triggered by NIC TX. +Usually, once the occupancy of the NIC TX input queue drops below a predefined threshold, +the port scheduler is woken up (interrupt based or polling based, +by continuously monitoring the queue occupancy) to push more packets into the queue. + +Internal Time Reference +""""""""""""""""""""""" + +The scheduler needs to keep track of time advancement for the credit logic, +which requires credit updates based on time (for example, subport and pipe traffic shaping, traffic class upper limit enforcement, and so on). + +Every time the scheduler decides to send a packet out to the NIC TX for transmission, the scheduler will increment its internal time reference accordingly. +Therefore, it is convenient to keep the internal time reference in units of bytes, +where a byte signifies the time duration required by the physical interface to send out a byte on the transmission medium. +This way, as a packet is scheduled for transmission, the time is incremented with (n + h), +where n is the packet length in bytes and h is the number of framing overhead bytes per packet. + +Internal Time Reference Re-synchronization +"""""""""""""""""""""""""""""""""""""""""" + +The scheduler needs to align its internal time reference to the pace of the port conveyor belt. +The reason is to make sure that the scheduler does not feed the NIC TX with more bytes than the line rate of the physical medium in order to prevent packet drop +(by the scheduler, due to the NIC TX input queue being full, or later on, internally by the NIC TX). + +The scheduler reads the current time on every dequeue invocation. +The CPU time stamp can be obtained by reading either the Time Stamp Counter (TSC) register or the High Precision Event Timer (HPET) register. +The current CPU time stamp is converted from number of CPU clocks to number of bytes: +*time_bytes = time_cycles / cycles_per_byte, where cycles_per_byte* +is the amount of CPU cycles that is equivalent to the transmission time for one byte on the wire +(e.g. for a CPU frequency of 2 GHz and a 10GbE port,*cycles_per_byte = 1.6*). + +The scheduler maintains an internal time reference of the NIC time. +Whenever a packet is scheduled, the NIC time is incremented with the packet length (including framing overhead). +On every dequeue invocation, the scheduler checks its internal reference of the NIC time against the current time: + +#. If NIC time is in the future (NIC time >= current time), no adjustment of NIC time is needed. + This means that scheduler is able to schedule NIC packets before the NIC actually needs those packets, so the NIC TX is well supplied with packets; + +#. If NIC time is in the past (NIC time < current time), then NIC time should be adjusted by setting it to the current time. + This means that the scheduler is not able to keep up with the speed of the NIC byte conveyor belt, + so NIC bandwidth is wasted due to poor packet supply to the NIC TX. + +Scheduler Accuracy and Granularity +"""""""""""""""""""""""""""""""""" + +The scheduler round trip delay (SRTD) is the time (number of CPU cycles) between two consecutive examinations of the same pipe by the scheduler. + +To keep up with the output port (that is, avoid bandwidth loss), +the scheduler should be able to schedule n packets faster than the same n packets are transmitted by NIC TX. + +The scheduler needs to keep up with the rate of each individual pipe, +as configured for the pipe token bucket, assuming that no port oversubscription is taking place. +This means that the size of the pipe token bucket should be set high enough to prevent it from overflowing due to big SRTD, +as this would result in credit loss (and therefore bandwidth loss) for the pipe. + +Credit Logic +^^^^^^^^^^^^ + +Scheduling Decision +""""""""""""""""""" + +The scheduling decision to send next packet from (subport S, pipe P, traffic class TC, queue Q) is favorable (packet is sent) +when all the conditions below are met: + +* Pipe P of subport S is currently selected by one of the port grinders;

Any bandwidth left | + | | | unused by the low-demand pipes is redistributed in equal portions to | + | | | the high-demand pipes. This way, the high-demand pipes are truncated | + | | | while the low-demand pipes are not impacted. | + | | | | + +-----+---------------------------+-------------------------------------------------------------------------+ + +Typically, the subport TC oversubscription feature is enabled only for the lowest priority traffic class (TC 3), +which is typically used for best effort traffic, +with the management plane preventing this condition from occurring for the other (higher priority) traffic classes. + +To ease implementation, it is also assumed that the upper limit for subport TC 3 is set to 100% of the subport rate, +and that the upper limit for pipe TC 3 is set to 100% of pipe rate for all subport member pipes. + +Implementation Overview +''''''''''''''''''''''' + +The algorithm computes a watermark, which is periodically updated based on the current demand experienced by the subport member pipes, +whose purpose is to limit the amount of traffic that each pipe is allowed to send for TC 3. +The watermark is computed at the subport level at the beginning of each traffic class upper limit enforcement period and +the same value is used by all the subport member pipes throughout the current enforcement period. +illustrates how the watermark computed as subport level at the beginning of each period is propagated to all subport member pipes. + +At the beginning of the current enforcement period (which coincides with the end of the previous enforcement period), +the value of the watermark is adjusted based on the amount of bandwidth allocated to TC 3 at the beginning of the previous period that +was not left unused by the subport member pipes at the end of the previous period. + +If there was subport TC 3 bandwidth left unused, +the value of the watermark for the current period is increased to encourage the subport member pipes to consume more bandwidth. +Otherwise, the value of the watermark is decreased to enforce equality of bandwidth consumption among subport member pipes for TC 3. + +The increase or decrease in the watermark value is done in small increments, +so several enforcement periods might be required to reach the equilibrium state. +This state can change at any moment due to variations in the demand experienced by the subport member pipes for TC 3, for example, +as a result of demand increase (when the watermark needs to be lowered) or demand decrease (when the watermark needs to be increased). + +When demand is low, the watermark is set high to prevent it from impeding the subport member pipes from consuming more bandwidth. +The highest value for the watermark is picked as the highest rate configured for a subport member pipe. +:numref:`table_qos_14` and :numref:`table_qos_15` illustrates the watermark operation. + +.. _table_qos_14: + +.. table:: Watermark Propagation from Subport Level to Member Pipes at the

Active Queues with Not Enough Credits +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The more queues the scheduler has to examine for packets and credits in order to select one packet, +the lower the performance of the scheduler is. + +The scheduler maintains the bitmap of active queues, which skips the non-active queues, +but in order to detect whether a specific pipe has enough credits, +the pipe has to be drilled down using the pipe dequeue state machine, +which consumes cycles regardless of the scheduling result +(no packets are produced or at least one packet is produced). + +This scenario stresses the importance of the policer for the scheduler performance: +if the pipe does not have enough credits, +its packets should be dropped as soon as possible (before they reach the hierarchical scheduler), +thus rendering the pipe queues as not active, +which allows the dequeue side to skip that pipe with no cycles being spent on investigating the pipe credits +that would result in a "not enough credits" status. + +Single Queue with 100% Line Rate +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The port scheduler performance is optimized for a large number of queues. +If the number of queues is small, +then the performance of the port scheduler for the same level of active traffic is expected to be worse than +the performance of a small set of message passing queues. + +.. _Dropper: + +Dropper +------- + +The purpose of the DPDK dropper is to drop packets arriving at a packet scheduler to avoid congestion. +The dropper supports the Random Early Detection (RED), +Weighted Random Early Detection (WRED) and tail drop algorithms. +:numref:`figure_blk_diag_dropper` illustrates how the dropper integrates with the scheduler. +The DPDK currently does not support congestion management +so the dropper provides the only method for congestion avoidance. + +.. _figure_blk_diag_dropper: + +.. figure:: img/blk_diag_dropper.* + + High-level Block Diagram of the DPDK Dropper + + +The dropper uses the Random Early Detection (RED) congestion avoidance algorithm as documented in the reference publication. +The purpose of the RED algorithm is to monitor a packet queue, +determine the current congestion level in the queue and decide whether an arriving packet should be enqueued or dropped. +The RED algorithm uses an Exponential Weighted Moving Average (EWMA) filter to compute average queue size which +gives an indication of the current congestion level in the queue. + +For each enqueue operation, the RED algorithm compares the average queue size to minimum and maximum thresholds. +Depending on whether the average queue size is below, above or in between these thresholds, +the RED algorithm calculates the probability that an arriving packet should be dropped and +makes a random decision based on this probability. + +The dropper also supports Weighted Random Early Detection (WRED) by allowing the scheduler to select +different RED configurations for the same packet queue at run-time. +In the case of severe congestion, the dropper resorts to tail drop. +This occurs when a packet queue has reached maximum capacity and cannot store any more packets. +In this situation, all arriving packets are dropped. + +The flow through the dropper is illustrated in :numref:`figure_flow_tru_droppper`. +The RED/WRED algorithm is exercised

sections. +The format of these parameters as specified to the dropper module API +corresponds to the format used by Cisco* in their RED implementation. +The minimum and maximum threshold parameters

+^^^^^^^^^^^^^^^^^^^^^^ + +The purpose of the EWMA Filter microblock is to filter queue size values to smooth out transient changes +that result from "bursty" traffic. +The output value is the average queue size which gives a more stable view of the current congestion level in the queue. + +The EWMA filter has one configuration parameter, filter weight, which determines how quickly +or slowly the

The sequence window is determined by the minimum +sequence number and the number of entries that the buffer was configured to hold. +For example, given a reorder buffer with 200 entries and a minimum sequence +number of 350, the sequence window has low and high limits of 350 and 550 +respectively. + +When inserting mbufs, the reorder library differentiates between valid, early +and late mbufs depending on the sequence number of the inserted mbuf: + +* valid: the sequence number is inside the window. +* late: the sequence number is outside the window and less than the low limit. +* early: the sequence number is outside the window and greater than the high + limit. + +The reorder buffer directly returns late mbufs and tries to accommodate early +mbufs. + + +Implementation Details +------------------------- + +The reorder library is implemented as a pair of buffers, which referred to as +the *Order* buffer and the *Ready* buffer. + +On an insert call, valid mbufs are inserted directly into the Order buffer and +late mbufs are returned to the user with an error. + +In the case of early mbufs, the reorder buffer will try to move the window +(incrementing the minimum sequence number) so that the mbuf becomes a valid one. +To that end, mbufs in the Order buffer are moved into the Ready buffer. +Any mbufs that have not arrived yet are ignored and therefore will become +late mbufs. +This means that as long as there is room in the Ready buffer, the window will +be moved to accommodate early mbufs that would otherwise be outside the +reordering window. + +For example, assuming that we have a buffer of 200 entries with a 350 minimum +sequence number, and we need to insert an early mbuf with 565 sequence number. +That means that we would need to move the windows at least 15 positions to +accommodate the mbuf. +The reorder buffer would try to move mbufs from at least the next 15 slots in +the Order buffer to the Ready buffer, as long as there is room in the Ready buffer. +Any gaps in the Order buffer at that point are skipped, and those packet will +be reported as late packets when they arrive. The process of moving packets +to the Ready buffer continues beyond the minimum required until a gap, +i.e. missing mbuf, in the Order buffer is encountered. + +When draining mbufs, the reorder buffer would return mbufs in the Ready +buffer first and then from the Order buffer until a gap is found (mbufs that +have not arrived yet). + +Use Case: Packet Distributor +------------------------------- + +An application using the DPDK packet distributor could make use of the reorder +library to transmit packets in the same order they were received. + +A basic packet distributor use case would consist of a distributor with +multiple workers cores. +The processing of packets by the workers is not guaranteed to be in order, +hence a reorder buffer can be used to order as many packets as possible. + +In such a scenario, the distributor assigns a sequence number to mbufs before +delivering them to the workers. +As the workers finish processing the packets, the distributor inserts those +mbufs into the reorder buffer and finally transmit drained mbufs. + +NOTE: Currently the reorder buffer is not thread safe so the same thread is +responsible for inserting and draining mbufs. diff --git a/dpdk/doc/guides/prog_guide/ring_lib.rst b/dpdk/doc/guides/prog_guide/ring_lib.rst new file mode 100644 index 0000000..5a9b613 --- /dev/null +++ b/dpdk/doc/guides/prog_guide/ring_lib.rst @@ -0,0 +1,357 @@ +..

Flow rules form the basis of this API. + +Flow rules can have several distinct actions (such as counting, +encapsulating, decapsulating before redirecting packets to a particular +queue, etc.), instead of relying on several rules to achieve this and having +applications deal with hardware implementation details regarding their +order. + +Support for different priority levels on a rule basis is provided, for +example in order to force a more specific rule to come before a more generic +one for packets matched by both. However hardware support for more than a +single priority level cannot be guaranteed. When supported, the number of +available priority levels is usually low, which is why they can also be +implemented in software by PMDs (e.g. missing priority levels may be +emulated by reordering rules). + +In order to remain as hardware-agnostic as possible, by default all rules +are considered to have the same priority, which means that the order between +overlapping rules (when a packet is matched by several filters) is +undefined. + +PMDs may refuse to create overlapping rules at a given priority level when +they can be detected (e.g. if a pattern matches an existing filter). + +Thus predictable results for a given priority level can only be achieved +with non-overlapping rules, using perfect matching on all protocol layers. + +Flow rules can also be grouped, the flow rule priority is specific to the +group they belong to. All flow rules in a given group are thus processed +either before or after another group. + +Support for multiple actions per rule may be implemented internally on top +of non-default hardware priorities, as a result both features may not be +simultaneously available to applications. + +Considering that allowed pattern/actions combinations cannot be known in +advance and would result in an impractically large number of capabilities to +expose, a method is provided to validate a given rule from the current +device configuration state. + +This enables applications to check if the rule types they need is supported +at initialization time, before starting their data path. This method can be +used anytime, its only requirement being that the resources needed by a rule +should exist (e.g. a target RX queue should be configured first). + +Each defined rule is associated with an opaque handle managed by the PMD, +applications are responsible for keeping it. These can be used for queries +and rules management, such as retrieving counters or other data and +destroying them. + +To avoid resource leaks on the PMD side, handles must be explicitly +destroyed by the application before releasing associated resources such as +queues and ports. + +The following sections cover: + +- **Attributes** (represented by ``struct rte_flow_attr``): properties of a + flow rule such as its direction (ingress or egress) and priority. + +- **Pattern item** (represented by ``struct rte_flow_item``): part of a + matching pattern that either matches specific packet data or traffic + properties. It can also describe properties of the pattern itself, such as + inverted matching. + +- **Matching pattern**: traffic properties to look for, a combination of any + number of items. + +- **Actions** (represented by ``struct rte_flow_action``): operations to + perform whenever a packet is matched by a pattern. + +Attributes +~~~~~~~~~~ + +Attribute: Group +^^^^^^^^^^^^^^^^ + +Flow rules can be grouped by assigning them a common group number. Lower +values have higher priority. Group 0 has the highest priority. + +Although optional, applications are encouraged to group similar rules as +much as possible to fully take advantage of hardware capabilities +(e.g. optimized matching) and work around limitations (e.g. a single pattern +type possibly allowed in a given group). + +Note that support for more than a single group is not guaranteed. + +Attribute: Priority +^^^^^^^^^^^^^^^^^^^ + +A priority level can be assigned to a flow rule. Like groups, lower values +denote higher priority, with 0 as the maximum. + +A rule with priority 0 in group 8 is always matched after a rule with +priority 8 in group 0. + +Group and priority levels are arbitrary and up to the application, they do +not need to be contiguous nor start from 0, however the maximum number +varies between devices and may be affected by existing flow rules. + +If a packet is matched by several rules of a given group for a given +priority level, the outcome is undefined. It can take any path, may be +duplicated or even cause unrecoverable errors. + +Note that support for more than a single priority level is not guaranteed. + +Attribute: Traffic direction +^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Flow rules can apply to inbound and/or outbound traffic (ingress/egress). + +Several pattern items and actions are valid and can be used in both +directions. At least one direction must be specified. + +Specifying both directions at once for a given rule is not recommended but +may be valid in a few cases (e.g. shared counters). + +Pattern item +~~~~~~~~~~~~ + +Pattern items fall in two categories: + +- Matching protocol headers and packet data (ANY, RAW, ETH, VLAN, IPV4, + IPV6, ICMP, UDP, TCP, SCTP, VXLAN, MPLS, GRE, ESP and so on), usually + associated with a specification structure. + +- Matching meta-data or affecting pattern processing (END, VOID, INVERT, PF, + VF, PORT and so on), often without a specification structure. + +Item specification structures are used to match specific values among +protocol fields (or item properties). Documentation describes for each item +whether they are associated with one and their type name if so. + +Up to three structures of the same type can be set for a given item: + +- ``spec``: values to match (e.g. a given IPv4 address). + +- ``last``: upper bound for an inclusive range with corresponding fields in + ``spec``. + +- ``mask``: bit-mask applied to both ``spec`` and ``last`` whose purpose is + to distinguish the values to take into account and/or partially mask them + out (e.g. in order to match an IPv4 address prefix). + +Usage restrictions and expected behavior: + +- Setting either ``mask`` or ``last`` without ``spec`` is an error. + +- Field values in ``last`` which are either 0 or equal to the corresponding + values in ``spec`` are ignored; they do not generate a range. Nonzero + values lower than those in ``spec`` are not supported. + +- Setting ``spec`` and optionally ``last`` without ``mask`` causes the PMD + to use the default mask defined for that item (defined as + ``rte_flow_item_{name}_mask`` constants). + +- Not setting any of them (assuming item type allows it) is equivalent to + providing an empty (zeroed) ``mask`` for broad (nonspecific) matching. + +- ``mask`` is a simple bit-mask applied before interpreting the contents of + ``spec`` and ``last``, which may yield unexpected results if not used + carefully. For example, if for an IPv4 address field, ``spec`` provides + *10.1.2.3*, ``last`` provides *10.3.4.5* and ``mask`` provides + *255.255.0.0*, the effective range becomes *10.1.0.0* to *10.3.255.255*. + +Example of an item specification matching an Ethernet header: + +.. _table_rte_flow_pattern_item_example: + +.. table:: Ethernet item + + +----------+----------+--------------------+ + | Field | Subfield | Value | + +==========+==========+====================+ + | ``spec`` | ``src`` | ``00:01:02:03:04`` | + | +----------+--------------------+ + | | ``dst`` | ``00:2a:66:00:01`` | + | +----------+--------------------+ + | | ``type`` | ``0x22aa`` | + +----------+----------+--------------------+ + | ``last`` | unspecified | + +----------+----------+--------------------+ + | ``mask`` | ``src`` | ``00:ff:ff:ff:00`` | + | +----------+--------------------+ + | | ``dst`` | ``00:00:00:00:ff`` | + | +----------+--------------------+ + | | ``type`` | ``0x0000`` | + +----------+----------+--------------------+ + +Non-masked bits stand for any value (shown as ``?`` below), Ethernet headers +with the following properties are thus matched: + +- ``src``: ``??:01:02:03:??`` +- ``dst``: ``??:??:??:??:01`` +- ``type``: ``0x????`` + +Matching pattern +~~~~~~~~~~~~~~~~ + +A pattern is formed by stacking items starting from the lowest protocol +layer to match.

PMDs initialize + this structure in case of error only. + +Return values: + +- 0 on success, a negative errno value otherwise and ``rte_errno`` is set. + +Isolated mode +------------- + +The general expectation for ingress traffic is that flow rules process it +first; the remaining unmatched or pass-through traffic usually ends up in a +queue (with or without RSS, locally or in some sub-device instance) +depending on the global configuration settings of a port. + +While fine from a compatibility standpoint, this approach makes drivers more +complex as they have to check for possible side effects outside of this API +when creating or destroying flow rules. It results in a more limited set of +available rule types due to the way device resources are assigned (e.g. no +support for the RSS action even on capable hardware). + +Given that nonspecific traffic can be handled by flow rules as well, +isolated mode is a means for applications to tell a driver that ingress on +the underlying port must be injected from the defined flow rules only; that +no default traffic is expected outside those rules. + +This has the following benefits: + +- Applications get finer-grained control over the kind of traffic they want + to receive (no traffic by default). + +- More importantly they control at what point nonspecific traffic is handled + relative to other flow rules, by adjusting priority levels. + +- Drivers can assign more hardware resources to flow rules and expand the + set of supported rule types. + +Because toggling isolated mode may cause profound changes to the ingress +processing path of a driver, it may not be possible to leave it once +entered. Likewise, existing flow rules or global configuration settings may +prevent a driver from entering isolated mode. + +Applications relying on this mode are therefore encouraged to toggle it as +soon as possible after device initialization, ideally before the first call +to ``rte_eth_dev_configure()`` to avoid possible failures due to conflicting +settings. + +Once effective, the following functionality has no effect on the underlying +port and may return errors such as ``ENOTSUP`` ("not supported"): + +- Toggling promiscuous mode. +- Toggling allmulticast mode. +- Configuring MAC addresses. +- Configuring multicast addresses. +- Configuring VLAN filters. +- Configuring Rx filters through the legacy API (e.g. FDIR). +- Configuring global RSS settings. + +.. code-block:: c + + int + rte_flow_isolate(uint16_t port_id, int set, struct rte_flow_error *error); + +Arguments: + +- ``port_id``: port identifier of Ethernet device. +- ``set``: nonzero to enter isolated mode, attempt to leave it otherwise. +- ``error``: perform verbose error reporting if not NULL. PMDs initialize + this structure in case of error only. + +Return values: + +- 0 on success, a negative errno value otherwise and ``rte_errno`` is set. + +Verbose error reporting +----------------------- + +The defined *errno* values may not be accurate enough for users or +application developers who want to investigate issues related to flow rules +management. A dedicated error object is defined for this purpose: + +.. code-block:: c + + enum rte_flow_error_type { + RTE_FLOW_ERROR_TYPE_NONE, /**< No error. */ + RTE_FLOW_ERROR_TYPE_UNSPECIFIED, /**< Cause unspecified. */ + RTE_FLOW_ERROR_TYPE_HANDLE, /**< Flow rule (handle). */ + RTE_FLOW_ERROR_TYPE_ATTR_GROUP, /**< Group field. */ + RTE_FLOW_ERROR_TYPE_ATTR_PRIORITY, /**< Priority field. */ + RTE_FLOW_ERROR_TYPE_ATTR_INGRESS, /**< Ingress field. */ + RTE_FLOW_ERROR_TYPE_ATTR_EGRESS, /**< Egress field. */ + RTE_FLOW_ERROR_TYPE_ATTR, /**< Attributes structure. */ + RTE_FLOW_ERROR_TYPE_ITEM_NUM, /**< Pattern length. */ + RTE_FLOW_ERROR_TYPE_ITEM, /**< Specific pattern item. */ + RTE_FLOW_ERROR_TYPE_ACTION_NUM, /**< Number of actions. */ + RTE_FLOW_ERROR_TYPE_ACTION, /**< Specific action. */ + }; + + struct rte_flow_error { + enum rte_flow_error_type type; /**< Cause field and error types. */ + const void *cause; /**< Object responsible for the error. */ + const char *message; /**< Human-readable error message. */ + }; + +Error type ``RTE_FLOW_ERROR_TYPE_NONE`` stands for no error, in which case +remaining fields can be ignored. Other error types describe the type of the +object pointed by ``cause``. + +If non-NULL, ``cause`` points to the object responsible for the error. For a +flow rule, this may be a pattern item or an individual action. + +If non-NULL, ``message`` provides a human-readable error message. + +This object is normally allocated by applications and set by PMDs in case of +error, the message points to a constant string which does not need to be +freed by the application, however its pointer can be considered valid only +as long as its associated DPDK port remains configured. Closing the +underlying device or unloading the PMD invalidates it. + +Helpers +------- + +Error initializer +~~~~~~~~~~~~~~~~~ + +.. code-block:: c + + static inline int + rte_flow_error_set(struct rte_flow_error *error, + int code, + enum rte_flow_error_type type, + const void *cause, + const char *message); + +This function initializes ``error`` (if non-NULL) with the provided +parameters and sets ``rte_errno`` to ``code``. A negative error ``code`` is +then returned. + +Caveats +------- + +- DPDK does not keep track of flow rules definitions or flow rule objects + automatically. Applications may keep track of the former and must keep + track of the latter. PMDs may also do it for internal needs, however this + must not be relied on by applications. + +- Flow rules are not maintained between successive port initializations. An + application exiting without releasing them and restarting must re-create + them from scratch. + +- API operations are synchronous and blocking (``EAGAIN`` cannot be + returned). + +- There is no provision for reentrancy/multi-thread safety, although nothing + should prevent different devices from being configured at the same + time. PMDs may protect their control path functions accordingly. + +- Stopping the data path (TX/RX) should not be necessary when managing flow + rules. If this cannot be achieved naturally or with workarounds (such as + temporarily replacing the burst function pointers), an appropriate error + code must be returned (``EBUSY``). + +- PMDs, not applications, are responsible for maintaining flow rules + configuration when stopping and restarting a port or performing other + actions which may affect them. They can only be destroyed explicitly by + applications. + +For devices exposing multiple ports sharing global settings affected by flow +rules: + +- All ports under DPDK control must behave consistently, PMDs are + responsible for making sure that existing flow rules on a port are not + affected by other ports. + +- Ports not under DPDK control (unaffected or handled by other applications) + are user's responsibility. They may affect existing flow rules and cause + undefined behavior. PMDs aware of this may prevent flow rules creation + altogether in such cases. + +PMD interface +------------- + +The PMD interface is defined in ``rte_flow_driver.h``. It is not subject to +API/ABI versioning constraints as it is not exposed to applications and may +evolve independently. + +It is currently implemented on top of the legacy filtering framework through +filter type *RTE_ETH_FILTER_GENERIC* that accepts the single operation +*RTE_ETH_FILTER_GET* to return PMD-specific *rte_flow* callbacks wrapped +inside ``struct rte_flow_ops``. + +This overhead is temporarily necessary in order to keep compatibility with +the legacy filtering framework, which should eventually disappear. + +- PMD callbacks implement exactly the interface described in `Rules + management`_, except for the port ID argument which has already been + converted to a pointer to the underlying ``struct rte_eth_dev``. + +- Public API functions do not process flow rules definitions at all before + calling PMD functions (no basic error checking, no validation + whatsoever). They only make sure these callbacks are non-NULL or return + the ``ENOSYS`` (function not supported) error. + +This interface additionally defines the following helper function: + +- ``rte_flow_ops_get()``: get generic flow operations structure from a + port. + +More will be added over time. + +Device compatibility +-------------------- + +No known implementation supports all the described features. + +Unsupported features or combinations are not expected to be fully emulated +in software by PMDs for performance reasons. Partially supported features +may be completed in software as long as hardware performs most of the work +(such as queue redirection and packet recognition). + +However PMDs are expected to do their best to satisfy application requests +by working around hardware limitations as long as doing so does not affect +the behavior of existing flow rules. + +The following sections provide a few examples of such cases and describe how +PMDs should handle them, they are based on limitations built into the +previous APIs. + +Global bit-masks +~~~~~~~~~~~~~~~~ + +Each flow rule comes with its own, per-layer bit-masks, while hardware may +support only a single, device-wide bit-mask for a given layer type, so that +two IPv4 rules cannot use different bit-masks. + +The expected behavior in this case is that PMDs automatically configure +global bit-masks according to the needs of the first flow rule created. + +Subsequent rules are allowed only if their bit-masks match those, the +``EEXIST`` error code should be returned otherwise. + +Unsupported layer types +~~~~~~~~~~~~~~~~~~~~~~~ + +Many protocols can be simulated by crafting patterns with the `Item: RAW`_ +type. + +PMDs can rely on this capability to simulate support for protocols with +headers not directly recognized by hardware. + +``ANY`` pattern item +~~~~~~~~~~~~~~~~~~~~ + +This pattern item stands for anything, which can be difficult to translate +to something hardware would understand, particularly if followed by more +specific types. + +Consider the following pattern: + +.. _table_rte_flow_unsupported_any: + +.. table:: Pattern with ANY as L3 + + +-------+-----------------------+ + | Index | Item | + +=======+=======================+ + | 0 | ETHER | + +-------+-----+---------+-------+ + | 1 | ANY | ``num`` | ``1`` | + +-------+-----+---------+-------+ + | 2 | TCP | + +-------+-----------------------+ + | 3 | END | + +-------+-----------------------+ + +Knowing that TCP does not make sense with something other than IPv4 and IPv6 +as L3, such a pattern may be translated to two flow rules instead: + +.. _table_rte_flow_unsupported_any_ipv4: + +.. table:: ANY replaced with IPV4 + + +-------+--------------------+ + | Index | Item | + +=======+====================+ + | 0 | ETHER | + +-------+--------------------+ + | 1 | IPV4 (zeroed mask) | + +-------+--------------------+ + | 2 | TCP | + +-------+--------------------+ + | 3 | END | + +-------+--------------------+ + +| + +.. _table_rte_flow_unsupported_any_ipv6: + +.. table:: ANY replaced with IPV6 + + +-------+--------------------+ + | Index | Item | + +=======+====================+ + | 0 | ETHER | + +-------+--------------------+ + | 1 | IPV6 (zeroed mask) | + +-------+--------------------+ + | 2 | TCP | + +-------+--------------------+ + | 3 | END | + +-------+--------------------+ + +Note that as soon as a ANY rule covers several layers, this approach may +yield a large number of hidden flow rules.

It returns an array of ``rte_security_capability`` structures +which contains all the capabilities for that device. + +Security Session Create/Free +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Security Sessions are created to store the immutable fields of a particular Security +Association for a particular protocol which is defined by a security session +configuration structure which is used in the operation processing of a packet flow. +Sessions are used to manage protocol specific information as well as crypto parameters. +Security sessions cache this immutable data in a optimal way for the underlying PMD +and this allows further acceleration of the offload of Crypto workloads. + +The Security framework provides APIs to create and free sessions for crypto/ethernet +devices, where sessions are mempool objects. It is the application's responsibility +to create and manage the session mempools. The mempool object size should be able to +accommodate the driver's private data of security session. + +Once the session mempools have been created, ``rte_security_session_create()`` +is used to allocate and initialize a session for the required crypto/ethernet device. + +Session APIs need a parameter ``rte_security_ctx`` to identify the crypto/ethernet +security ops. This parameter can be retrieved using the APIs +``rte_cryptodev_get_sec_ctx()`` (for crypto device) or ``rte_eth_dev_get_sec_ctx`` +(for ethernet port). + +Sessions already created can be updated with ``rte_security_session_update()``. + +When a session is no longer used, the user must call ``rte_security_session_destroy()`` +to free the driver private session data and return the memory back to the mempool. + +For look aside protocol offload to hardware crypto device, the ``rte_crypto_op`` +created by the application is attached to the security session by the API +``rte_security_attach_session()``. + +For Inline Crypto and Inline protocol offload, device specific defined metadata is +updated in the mbuf using ``rte_security_set_pkt_metadata()`` if +``DEV_TX_OFFLOAD_SEC_NEED_MDATA`` is set. + +For inline protocol offloaded ingress traffic, the application can register a +pointer, ``userdata`` , in the security session.

Service core support is built into the EAL, and +an API is provided to optionally allow applications to control how the service +cores are used at runtime. + +The service cores concept is built up out of services (components of DPDK that +require CPU cycles to operate) and service cores (DPDK lcores, tasked with +running services). The power of the service core concept is that the mapping +between service cores and services can be configured to abstract away the +difference between platforms and environments. + +For example, the Eventdev has hardware and software PMDs.

The API is based on BSD callout() with a few differences. +Refer to the `callout manual `_. + +Implementation Details +---------------------- + +Timers are tracked on a per-lcore basis, +with all pending timers for a core being maintained in order of timer expiry in a skiplist data structure. +The skiplist used has ten levels and each entry in the table appears in each level with probability ¼^level. +This means that all entries are present in level 0, 1 in every 4 entries is present at level 1, +one in every 16 at level 2 and so on up to level 9. +This means that adding and removing entries from the timer list for a core can be done in log(n) time, +up to 4^10 entries, that is, approximately 1,000,000 timers per lcore. + +A timer structure contains a special field called status, +which is a union of a timer state (stopped, pending, running, config) and an owner (lcore id). +Depending on the timer state, we know if a timer is present in a list or not: + +* STOPPED: no owner, not in a list + +* CONFIG: owned by a core, must not be modified by another core, maybe in a list or not, depending on previous state + +* PENDING: owned by a core, present in a list + +* RUNNING: owned by a core, must not be modified by another core, present in a list + +Resetting or stopping a timer while it is in a CONFIG or RUNNING state is not allowed. +When modifying the state of a timer, +a Compare And Swap instruction should be used to guarantee that the status (state+owner) is modified atomically. + +Inside the rte_timer_manage() function, +the skiplist is used as a regular list by iterating along the level 0 list, which contains all timer entries, +until an entry which has not yet expired has been encountered. +To improve performance in the case where there are entries in the timer list but none of those timers have yet expired, +the expiry time of the first list entry is maintained within the per-core timer list structure itself. +On 64-bit platforms, this value can be checked without the need to take a lock on the overall structure. +(Since expiry times are maintained as 64-bit values, +a check on the value cannot be done on 32-bit platforms without using either a compare-and-swap (CAS) instruction or using a lock, +so this additional check is skipped in favor of checking as normal once the lock has been taken.) +On both 64-bit and 32-bit platforms, +a call to rte_timer_manage() returns without taking a lock in the case where the timer list for the calling core is empty. + +Use Cases +--------- + +The timer library is used for periodic calls, such as garbage collectors, or some state machines (ARP, bridging, and so on). + +References +---------- + +* `callout manual `_ + - The callout facility that provides timers with a mechanism to execute a function at a given time. + +* `HPET `_ + - Information about the High Precision Event Timer (HPET). diff --git a/dpdk/doc/guides/prog_guide/traffic_management.rst b/dpdk/doc/guides/prog_guide/traffic_management.rst new file mode 100644 index 0000000..98ac431 --- /dev/null +++ b/dpdk/doc/guides/prog_guide/traffic_management.rst @@ -0,0 +1,223 @@ +..

The APIs supports the information disclosure at the TM level, at +any hierarchical level of the TM and at any node level of the specific +hierarchical level. Such information helps towards rapid understanding of +whether a specific implementation does meet the needs to the user application. + +At the TM level, users can get high level idea with the help of various +parameters such as maximum number of nodes, maximum number of hierarchical +levels, maximum number of shapers, maximum number of private shapers, type of +scheduling algorithm (Strict Priority, Weighted Fair Queueing , etc.), etc., +supported by the implementation. + +Likewise, users can query the capability of the TM at the hierarchical level to +have more granular knowledge about the specific level. The various parameters +such as maximum number of nodes at the level, maximum number of leaf/non-leaf +nodes at the level, type of the shaper(dual rate, single rate) supported at +the level if node is non-leaf type etc., are exposed as a result of +hierarchical level capability query. + +Finally, the node level capability API offers knowledge about the capability +supported by the node at any specific level. The information whether the +support is available for private shaper, dual rate shaper, maximum and minimum +shaper rate, etc. is exposed by node level capability API. + + +Scheduling Algorithms +--------------------- + +The fundamental scheduling algorithms that are supported are Strict Priority +(SP) and Weighted Fair Queuing (WFQ). The SP and WFQ algorithms are supported +at the level of each node of the scheduling hierarchy, regardless of the node +level/position in the tree. The SP algorithm is used to schedule between +sibling nodes with different priority, while WFQ is used to schedule between +groups of siblings that have the same priority. + +Algorithms such as Weighed Round Robin (WRR), byte-level WRR, Deficit WRR +(DWRR), etc are considered approximations of the ideal WFQ and are therefore +assimilated to WFQ, although an associated implementation-dependent accuracy, +performance and resource usage trade-off might exist. + + +Traffic Shaping +--------------- + +The TM API provides support for single rate and dual rate shapers (rate +limiters) for the hierarchy nodes, subject to the specific implementation +support being available. + +Each hierarchy node has zero or one private shaper (only one node using it) +and/or zero, one or several shared shapers (multiple nodes use the same shaper +instance). A private shaper is used to perform traffic shaping for a single +node, while a shared shaper is used to perform traffic shaping for a group of +nodes. + +The configuration of private and shared shapers is done through the definition +of shaper profiles. Any shaper profile (single rate or dual rate shaper) can be +used by one or several shaper instances (either private or shared). + +Single rate shapers use a single token bucket. Therefore, single rate shaper is +configured by setting the rate of the committed bucket to zero, which +effectively disables this bucket. The peak bucket is used to limit the rate +and the burst size for the single rate shaper. Dual rate shapers use both the +committed and the peak token buckets. The rate of the peak bucket has to be +bigger than zero, as well as greater than or equal to the rate of the committed +bucket. + + +Congestion Management +--------------------- + +Congestion management is used to control the admission of packets into a packet +queue or group of packet queues on congestion. The congestion management +algorithms that are supported are: Tail Drop, Head Drop and Weighted Random +Early Detection (WRED). They are made available for every leaf node in the +hierarchy, subject to the specific implementation supporting them. +On request of writing a new packet into the current queue while the queue is +full, the Tail Drop algorithm drops the new packet while leaving the queue +unmodified, as opposed to the Head Drop* algorithm, which drops the packet +at the head of the queue (the oldest packet waiting in the queue) and admits +the new packet at the tail of the queue. + +The Random Early Detection (RED) algorithm works by proactively dropping more +and more input packets as the queue occupancy builds up. When the queue is full +or almost full, RED effectively works as Tail Drop. The Weighted RED (WRED) +algorithm uses a separate set of RED thresholds for each packet color and uses +separate set of RED thresholds for each packet color. + +Each hierarchy leaf node with WRED enabled as its congestion management mode +has zero or one private WRED context (only one leaf node using it) and/or zero, +one or several shared WRED contexts (multiple leaf nodes use the same WRED +context). A private WRED context is used to perform congestion management for +a single leaf node, while a shared WRED context is used to perform congestion +management for a group of leaf nodes. + +The configuration of WRED private and shared contexts is done through the +definition of WRED profiles. Any WRED profile can be used by one or several +WRED contexts (either private or shared). + + +Packet Marking +-------------- +The TM APIs have been provided to support various types of packet marking such +as VLAN DEI packet marking (IEEE 802.1Q), IPv4/IPv6 ECN marking of TCP and SCTP +packets (IETF RFC 3168) and IPv4/IPv6 DSCP packet marking (IETF RFC 2597). +All VLAN frames of a given color get their DEI bit set if marking is enabled +for this color. In case, when marking for a given color is not enabled, the +DEI bit is left as is (either set or not). + +All IPv4/IPv6 packets of a given color with ECN set to 2’b01 or 2’b10 carrying +TCP or SCTP have their ECN set to 2’b11 if the marking feature is enabled for +the current color, otherwise the ECN field is left as is. + +All IPv4/IPv6 packets have their color marked into DSCP bits 3 and 4 as +follows: green mapped to Low Drop Precedence (2’b01), yellow to Medium (2’b10) +and red to High (2’b11). Marking needs to be explicitly enabled for each color; +when not enabled for a given color, the DSCP field of all packets with that +color is left as is. + + +Steps to Setup the Hierarchy +---------------------------- + +The TM hierarchical tree consists of leaf nodes and non-leaf nodes. Each leaf +node sits on top of a scheduling queue of the current Ethernet port. Therefore, +the leaf nodes have predefined IDs in the range of 0... (N-1), where N is the +number of scheduling queues of the current Ethernet port. The non-leaf nodes +have their IDs generated by the application outside of the above range, which +is reserved for leaf nodes. + +Each non-leaf node has multiple inputs (its children nodes) and single output +(which is input to its parent node). It arbitrates its inputs using Strict +Priority (SP) and Weighted Fair Queuing (WFQ) algorithms to schedule input +packets to its output while observing its shaping (rate limiting) constraints. + +The children nodes with different priorities are scheduled using the SP +algorithm based on their priority, with 0 as the highest priority. Children +with the same priority are scheduled using the WFQ algorithm according to their +weights. The WFQ weight of a given child node is relative to the sum of the +weights of all its sibling nodes that have the same priority, with 1 as the +lowest weight. For each SP priority, the WFQ weight mode can be set as either +byte-based or packet-based. + + +Initial Hierarchy Specification +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The hierarchy is specified by incrementally adding nodes to build up the +scheduling tree. The first node that is added to the hierarchy becomes the root +node and all the nodes that are subsequently added have to be added as +descendants of the root node. The parent of the root node has to be specified +as RTE_TM_NODE_ID_NULL and there can only be one node with this parent ID +(i.e. the root node). The unique ID that is assigned to each node when the node +is created is further used to update the node configuration or to connect +children nodes to it. + +During this phase, some limited checks on the hierarchy specification can be +conducted, usually limited in scope to the current node, its parent node and +its sibling nodes. At this time, since the hierarchy is not fully defined, +there is typically no real action performed by the underlying implementation. + + +Hierarchy Commit +~~~~~~~~~~~~~~~~ + +The hierarchy commit API is called during the port initialization phase (before +the Ethernet port is started) to freeze the start-up hierarchy. This function +typically performs the following steps: + +* It validates the start-up hierarchy that was previously defined for the + current port through successive node add API invocations. +* Assuming successful validation, it performs all the necessary implementation + specific operations to install the specified hierarchy on the current port, + with immediate effect once the port is started. + +This function fails when the currently configured hierarchy is not supported by +the Ethernet port, in which case the user can abort or try out another +hierarchy configuration (e.g. a hierarchy with less leaf nodes), which can be +built from scratch or by modifying the existing hierarchy configuration. Note +that this function can still fail due to other causes (e.g. not enough memory +available in the system, etc.), even though the specified hierarchy is +supported in principle by the current port. + + +Run-Time Hierarchy Updates +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The TM API provides support for on-the-fly changes to the scheduling hierarchy, +thus operations such as node add/delete, node suspend/resume, parent node +update, etc., can be invoked after the Ethernet port has been started, subject +to the specific implementation supporting them. The set of dynamic updates +supported by the implementation is advertised through the port capability set. diff --git a/dpdk/doc/guides/prog_guide/traffic_metering_and_policing.rst b/dpdk/doc/guides/prog_guide/traffic_metering_and_policing.rst new file mode 100644 index 0000000..dc9bdd5 --- /dev/null +++ b/dpdk/doc/guides/prog_guide/traffic_metering_and_policing.rst @@ -0,0 +1,74 @@ +..

Whether an MTR object is private to a +flow or potentially shared by several flows has to be specified at its +creation time. + +Once successfully created, an MTR object is hooked into the RX processing path +of the Ethernet device by linking it to one or several flows through the +dedicated "meter" flow action. One or several "meter" actions can be registered +for the same flow. An MTR object can only be destroyed if there are no flows +using it. + +Run-time processing +------------------- + +Traffic metering determines the color for the current packet (green, yellow, +red) based on the previous history for this flow as maintained by the MTR +object. The policer can do nothing, override the color the packet or drop the +packet. Statistics counters are maintained for MTR object, as configured. + +The processing done for each input packet hitting an MTR object is: + +* Traffic metering: The packet is assigned a color (the meter output color) + based on the previous traffic history reflected in the current state of the + MTR object, according to the specific traffic metering algorithm. The + traffic metering algorithm can typically work in color aware mode, in which + case the input packet already has an initial color (the input color), or in + color blind mode, which is equivalent to considering all input packets + initially colored as green. + +* Policing: There is a separate policer action configured for each meter + output color, which can: + + * Drop the packet. + + * Keep the same packet color: the policer output color matches the meter + output color (essentially a no-op action). + + * Recolor the packet: the policer output color is set to a different color + than the meter output color. The policer output color is the output color + of the packet, which is set in the packet meta-data (i.e. struct + ``rte_mbuf::sched::color``). + +* Statistics: The set of counters maintained for each MTR object is + configurable and subject to the implementation support.

In another words, it allows the user +to fetch/put packets from/to the VM virtio net device. To achieve this, a +vhost library should be able to: + +* Access the guest memory: + + For QEMU, this is done by using the ``-object memory-backend-file,share=on,...`` + option. Which means QEMU will create a file to serve as the guest RAM. + The ``share=on`` option allows another process to map that file, which + means it can access the guest RAM. + +* Know all the necessary information about the vring: + + Information such as where the available ring is stored. Vhost defines some + messages (passed through a Unix domain socket file) to tell the backend all + the information it needs to know how to manipulate the vring. + + +Vhost API Overview +------------------ + +The following is an overview of some key Vhost API functions: + +* ``rte_vhost_driver_register(path, flags)`` + + This function registers a vhost driver into the system. ``path`` specifies + the Unix domain socket file path. + + Currently supported flags are: + + - ``RTE_VHOST_USER_CLIENT`` + + DPDK vhost-user will act as the client when this flag is given. See below + for an explanation. + + - ``RTE_VHOST_USER_NO_RECONNECT`` + + When DPDK vhost-user acts as the client it will keep trying to reconnect + to the server (QEMU) until it succeeds. This is useful in two cases: + + * When QEMU is not started yet. + * When QEMU restarts (for example due to a guest OS reboot). + + This reconnect option is enabled by default. However, it can be turned off + by setting this flag. + + - ``RTE_VHOST_USER_DEQUEUE_ZERO_COPY`` + + Dequeue zero copy will be enabled when this flag is set. It is disabled by + default. + + There are some truths (including limitations) you might want to know while + setting this flag: + + * zero copy is not good for small packets (typically for packet size below + 512). + + * zero copy is really good for VM2VM case. For iperf between two VMs, the + boost could be above 70% (when TSO is enableld). + + * for VM2NIC case, the ``nb_tx_desc`` has to be small enough: <= 64 if virtio + indirect feature is not enabled and <= 128 if it is enabled. + + This is because when dequeue zero copy is enabled, guest Tx used vring will + be updated only when corresponding mbuf is freed. Thus, the nb_tx_desc + has to be small enough so that the PMD driver will run out of available + Tx descriptors and free mbufs timely. Otherwise, guest Tx vring would be + starved. + + * Guest memory should be backended with huge pages to achieve better + performance. Using 1G page size is the best. + + When dequeue zero copy is enabled, the guest phys address and host phys + address mapping has to be established. Using non-huge pages means far + more page segments. To make it simple, DPDK vhost does a linear search + of those segments, thus the fewer the segments, the quicker we will get + the mapping. NOTE: we may speed it by using tree searching in future. + + - ``RTE_VHOST_USER_IOMMU_SUPPORT`` + + IOMMU support will be enabled when this flag is set. It is disabled by + default. + + Enabling this flag makes possible to use guest vIOMMU to protect vhost + from accessing memory the virtio device isn't allowed to, when the feature + is negotiated and an IOMMU device is declared. + + However, this feature enables vhost-user's reply-ack protocol feature, + which implementation is buggy in Qemu v2.7.0-v2.9.0 when doing multiqueue. + Enabling this flag with these Qemu version results in Qemu being blocked + when multiple queue pairs are declared. + +* ``rte_vhost_driver_set_features(path, features)`` + + This function sets the feature bits the vhost-user driver supports. The + vhost-user driver could be vhost-user net, yet it could be something else, + say, vhost-user SCSI. + +* ``rte_vhost_driver_callback_register(path, vhost_device_ops)`` + + This function registers a set of callbacks, to let DPDK applications take + the appropriate action when some events happen. The following events are + currently supported: + + * ``new_device(int vid)`` + + This callback is invoked when a virtio device becomes ready. ``vid`` + is the vhost device ID. + + * ``destroy_device(int vid)`` + + This callback is invoked when a virtio device is paused or shut down. + + * ``vring_state_changed(int vid, uint16_t queue_id, int enable)`` + + This callback is invoked when a specific queue's state is changed, for + example to enabled or disabled. + + * ``features_changed(int vid, uint64_t features)`` + + This callback is invoked when the features is changed. For example, + ``VHOST_F_LOG_ALL`` will be set/cleared at the start/end of live + migration, respectively. + + * ``new_connection(int vid)`` + + This callback is invoked on new vhost-user socket connection. If DPDK + acts as the server the device should not be deleted before + ``destroy_connection`` callback is received. + + * ``destroy_connection(int vid)`` + + This callback is invoked when vhost-user socket connection is closed. + It indicates that device with id ``vid`` is no longer in use and can be + safely deleted. + +* ``rte_vhost_driver_disable/enable_features(path, features))`` + + This function disables/enables some features. For example, it can be used to + disable mergeable buffers and TSO features, which both are enabled by + default. + +* ``rte_vhost_driver_start(path)`` + + This function triggers the vhost-user negotiation. It should be invoked at + the end of initializing a vhost-user driver. + +* ``rte_vhost_enqueue_burst(vid, queue_id, pkts, count)`` + + Transmits (enqueues) ``count`` packets from host to guest. + +* ``rte_vhost_dequeue_burst(vid, queue_id, mbuf_pool, pkts, count)`` + + Receives (dequeues) ``count`` packets from guest, and stored them at ``pkts``. + +Vhost-user Implementations +-------------------------- + +Vhost-user uses Unix domain sockets for passing messages. This means the DPDK +vhost-user implementation has two options: + +* DPDK vhost-user acts as the server. + + DPDK will create a Unix domain socket server file and listen for + connections from the frontend. + + Note, this is the default mode, and the only mode before DPDK v16.07. + + +* DPDK vhost-user acts as the client. + + Unlike the server mode, this mode doesn't create the socket file; + it just tries to connect to the server (which responses to create the + file instead). + + When the DPDK vhost-user application restarts, DPDK vhost-user will try to + connect to the server again. This is how the "reconnect" feature works. + + .. Note:: + * The "reconnect" feature requires **QEMU v2.7** (or above). + + * The vhost supported features must be exactly the same before and + after the restart. For example, if TSO is disabled and then enabled, + nothing will work and issues undefined might happen. + +No matter which mode is used, once a connection is established, DPDK +vhost-user will start receiving and processing vhost messages from QEMU. + +For messages with a file descriptor, the file descriptor can be used directly +in the vhost process as it is already installed by the Unix domain socket. + +The supported vhost messages are: + +* ``VHOST_SET_MEM_TABLE`` +* ``VHOST_SET_VRING_KICK`` +* ``VHOST_SET_VRING_CALL`` +* ``VHOST_SET_LOG_FD`` +* ``VHOST_SET_VRING_ERR`` + +For ``VHOST_SET_MEM_TABLE`` message, QEMU will send information for each +memory region and its file descriptor in the ancillary data of the message. +The file descriptor is used to map that region. + +``VHOST_SET_VRING_KICK`` is used as the signal to put the vhost device into +the data plane, and ``VHOST_GET_VRING_BASE`` is used as the signal to remove +the vhost device from the data plane. + +When the socket connection is closed, vhost will destroy the device. + +Vhost supported vSwitch reference +--------------------------------- + +For more vhost details and how to support vhost in vSwitch, please refer to +the vhost example in the DPDK Sample Applications Guide. diff --git a/dpdk/doc/guides/prog_guide/writing_efficient_code.rst b/dpdk/doc/guides/prog_guide/writing_efficient_code.rst new file mode 100644 index 0000000..849f63e --- /dev/null +++ b/dpdk/doc/guides/prog_guide/writing_efficient_code.rst @@ -0,0 +1,220 @@ +.. SPDX-License-Identifier: BSD-3-Clause + Copyright(c) 2010-2014 Intel Corporation. + +Writing Efficient Code +====================== + +This chapter provides some tips for developing efficient code using the DPDK. +For additional and more general information, +please refer to the *Intel® 64 and IA-32 Architectures Optimization Reference Manual* +which is a valuable reference to writing efficient code. + +Memory +------ + +This section describes some key memory considerations when developing applications in the DPDK environment. + +Memory Copy: Do not Use libc in the Data Plane +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Many libc functions are available in the DPDK, via the Linux* application environment. +This can ease the porting of applications and the development of the configuration plane. +However, many of these functions are not designed for performance. +Functions such as memcpy() or strcpy() should not be used in the data plane. +To copy small structures, the preference is for a simpler technique that can be optimized by the compiler. +Refer to the *VTune™ Performance Analyzer Essentials* publication from Intel Press for recommendations. + +For specific functions that are called often, +it is also a good idea to provide a self-made optimized function, which should be declared as static inline. + +The DPDK API provides an optimized rte_memcpy() function. + +Memory Allocation +~~~~~~~~~~~~~~~~~ + +Other functions of libc, such as malloc(), provide a flexible way to allocate and free memory. +In some cases, using dynamic allocation is necessary, +but it is really not advised to use malloc-like functions in the data plane because +managing a fragmented heap can be costly and the allocator may not be optimized for parallel allocation. + +If you really need dynamic allocation in the data plane, it is better to use a memory pool of fixed-size objects. +This API is provided by librte_mempool. +This data structure provides several services that increase performance, such as memory alignment of objects, +lockless access to objects, NUMA awareness, bulk get/put and per-lcore cache. +The rte_malloc () function uses a similar concept to mempools. + +Concurrent Access to the Same Memory Area +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Read-Write (RW) access operations by several lcores to the same memory area can generate a lot of data cache misses, +which are very costly. +It is often possible to use per-lcore variables, for example, in the case of statistics. +There are at least two solutions for this: + +* Use RTE_PER_LCORE variables. Note that in this case, data on lcore X is not available to lcore Y. + +* Use a table of structures (one per lcore). In this case, each structure must be cache-aligned. + +Read-mostly variables can be shared among lcores without performance losses if there are no RW variables in the same cache line. + +NUMA +~~~~ + +On a NUMA system, it is preferable to access local memory since remote memory access is slower. +In the DPDK, the memzone, ring, rte_malloc and mempool APIs provide a way to create a pool on a specific socket. + +Sometimes, it can be a good idea to duplicate data to optimize speed. +For read-mostly variables that are often accessed, +it should not be a problem to keep them in one socket only, since data will be present in cache. + +Distribution Across Memory Channels +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Modern memory controllers have several memory channels that can load or store data in parallel. +Depending on the memory controller and its configuration, +the number of channels and the way the memory is distributed across the channels varies. +Each channel has a bandwidth limit, +meaning that if all memory access operations are done on the first channel only, there is a potential bottleneck. + +By default, the :ref:`Mempool Library ` spreads the addresses of objects among memory channels. + +Locking memory pages +~~~~~~~~~~~~~~~~~~~~ + +The underlying operating system is allowed to load/unload memory pages at its own discretion. +These page loads could impact the performance, as the process is on hold when the kernel fetches them. + +To avoid these you could pre-load, and lock them into memory with the ``mlockall()`` call. + +.. code-block:: c + + if (mlockall(MCL_CURRENT | MCL_FUTURE)) { + RTE_LOG(NOTICE, USER1, "mlockall() failed with error \"%s\"\n", + strerror(errno)); + } + +Communication Between lcores +---------------------------- + +To provide a message-based communication between lcores, +it is advised to use the DPDK ring API, which provides a lockless ring implementation. + +The ring supports bulk and burst access, +meaning that it is possible to read several elements from the ring with only one costly atomic operation +(see :doc:`ring_lib`). +Performance is greatly improved when using bulk access operations. + +The code algorithm that dequeues messages may be something similar to the following: + +.. code-block:: c + + #define MAX_BULK 32 + + while (1) { + /* Process as many elements as can be dequeued. */ + count = rte_ring_dequeue_burst(ring, obj_table, MAX_BULK, NULL); + if (unlikely(count == 0)) + continue; + + my_process_bulk(obj_table, count); + } + +PMD Driver +---------- + +The DPDK Poll Mode Driver (PMD) is also able to work in bulk/burst mode, +allowing the factorization of some code for each call in the send or receive function. + +Avoid partial writes. +When PCI devices write to system memory through DMA, +it costs less if the write operation is on a full cache line as opposed to part of it. +In the PMD code, actions have been taken to avoid partial writes as much as possible. + +Lower Packet Latency +~~~~~~~~~~~~~~~~~~~~ + +Traditionally, there is a trade-off between throughput and latency. +An application can be tuned to achieve a high throughput, +but the end-to-end latency of an average packet will typically increase as a result. +Similarly, the application can be tuned to have, on average, +a low end-to-end latency, at the cost of lower throughput. + +In order to achieve higher throughput, +the DPDK attempts to aggregate the cost of processing each packet individually by processing packets in bursts. + +Using the testpmd application as an example, +the burst size can be set on the command line to a value of 16 (also the default value). +This allows the application to request 16 packets at a time from the PMD. +The testpmd application then immediately attempts to transmit all the packets that were received, +in this case, all 16 packets. + +The packets are not transmitted until the tail pointer is updated on the corresponding TX queue of the network port. +This behavior is desirable when tuning for high throughput because +the cost of tail pointer updates to both the RX and TX queues can be spread across 16 packets, +effectively hiding the relatively slow MMIO cost of writing to the PCIe* device. +However, this is not very desirable when tuning for low latency because +the first packet that was received must also wait for another 15 packets to be received. +It cannot be transmitted until the other 15 packets have also been processed because +the NIC will not know to transmit the packets until the TX tail pointer has been updated, +which is not done until all 16 packets have been processed for transmission. + +To consistently achieve low latency, even under heavy system load, +the application developer should avoid processing packets in bunches. +The testpmd application can be configured from the command line to use a burst value of 1. +This will allow a single packet to be processed at a time, providing lower latency, +but with the added cost of lower throughput. + +Locks and Atomic Operations +--------------------------- + +Atomic operations imply a lock prefix before the instruction, +causing the processor's LOCK# signal to be asserted during execution of the following instruction. +This has a big impact on performance in a multicore environment. + +Performance can be improved by avoiding lock mechanisms in the data plane. +It can often be replaced by other solutions like per-lcore variables. +Also, some locking techniques are more efficient than others. +For instance, the Read-Copy-Update (RCU) algorithm can frequently replace simple rwlocks. + +Coding Considerations +--------------------- + +Inline Functions +~~~~~~~~~~~~~~~~ + +Small functions can be declared as static inline in the header file. +This avoids the cost of a call instruction (and the associated context saving). +However, this technique is not always efficient; it depends on many factors including the compiler. + +Branch Prediction +~~~~~~~~~~~~~~~~~ + +The Intel® C/C++ Compiler (icc)/gcc built-in helper functions likely() and unlikely() +allow the developer to indicate if a code branch is likely to be taken or not. +For instance: + +.. code-block:: c + + if (likely(x > 1)) + do_stuff(); + +Setting the Target CPU Type +--------------------------- + +The DPDK supports CPU microarchitecture-specific optimizations by means of CONFIG_RTE_MACHINE option +in the DPDK configuration file. +The degree of optimization depends on the compiler's ability to optimize for a specific microarchitecture, +therefore it is preferable to use the latest compiler versions whenever possible. + +If the compiler version does not support the specific feature set (for example, the Intel® AVX instruction set), +the build process gracefully degrades to whatever latest feature set is supported by the compiler. + +Since the build and runtime targets may not be the same, +the resulting binary also contains a platform check that runs before the +main() function and checks if the current machine is suitable for running the binary. + +Along with compiler optimizations, +a set of preprocessor defines are automatically added to the build process (regardless of the compiler version). +These defines correspond to the instruction sets that the target CPU should be able to support. +For example, a binary compiled for any SSE4.2-capable processor will have RTE_MACHINE_CPUFLAG_SSE4_2 defined, +thus enabling compile-time code path selection for different platforms. diff --git a/dpdk/doc/guides/rel_notes/deprecation.rst b/dpdk/doc/guides/rel_notes/deprecation.rst new file mode 100644 index 0000000..e9fcb69 --- /dev/null +++ b/dpdk/doc/guides/rel_notes/deprecation.rst @@ -0,0 +1,179 @@ +ABI and API Deprecation +======================= + +See the :doc:`guidelines document for details of the ABI policy `. +API and ABI deprecation notices are to be posted here. + + +Deprecation Notices +------------------- + +* eal: both declaring and identifying devices will be streamlined in v18.05. + New functions will appear to query a specific port from buses, classes of + device and device drivers.

This modification will only impact the PMDs, not the + applications. + +* ethdev: functions add rx/tx callback will return named opaque type + ``rte_eth_add_rx_callback()``, ``rte_eth_add_first_rx_callback()`` and + ``rte_eth_add_tx_callback()`` functions currently return callback object as + ``void \*`` but APIs to delete callbacks get ``struct rte_eth_rxtx_callback \*`` + as parameter. For consistency functions adding callback will return + ``struct rte_eth_rxtx_callback \*`` instead of ``void \*``. + +* ethdev: The size of variables ``flow_types_mask`` in + ``rte_eth_fdir_info structure``, ``sym_hash_enable_mask`` and + ``valid_bit_mask`` in ``rte_eth_hash_global_conf`` structure + will be increased from 32 to 64 bits to fulfill hardware requirements. + This change will break existing ABI as size of the structures will increase. + +* ethdev: ``rte_eth_dev_get_sec_ctx()`` fix port id storage + ``rte_eth_dev_get_sec_ctx()`` is using ``uint8_t`` for ``port_id``, + which should be ``uint16_t``. + +* i40e: The default flexible payload configuration which extracts the first 16 + bytes of the payload for RSS will be deprecated starting from 18.02. If + required the previous behavior can be configured using existing flow + director APIs. There is no ABI/API break. This change will just remove a + global configuration setting and require explicit configuration. + +* librte_meter: The API will change to accommodate configuration profiles. + Most of the API functions will have an additional opaque parameter. + +* ring: The alignment constraints on the ring structure will be relaxed + to one cache line instead of two, and an empty cache line padding will + be added between the producer and consumer structures. The size of the + structure and the offset of the fields will remain the same on + platforms with 64B cache line, but will change on other platforms. diff --git a/dpdk/doc/guides/rel_notes/index.rst b/dpdk/doc/guides/rel_notes/index.rst new file mode 100644 index 0000000..d8b5dfe --- /dev/null +++ b/dpdk/doc/guides/rel_notes/index.rst @@ -0,0 +1,25 @@ +..

describes known issues with the DPDK software that aren't covered in the version specific release +notes sections. + + +Unit Test for Link Bonding may fail at test_tlb_tx_burst() +---------------------------------------------------------- + +**Description**: + Unit tests will fail in ``test_tlb_tx_burst()`` function with error for uneven distribution of packets. + +**Implication**: + Unit test link_bonding_autotest will fail. + +**Resolution/Workaround**: + There is no workaround available. + +**Affected Environment/Platform**: + Fedora 20. + +**Driver/Module**: + Link Bonding. + + +Pause Frame Forwarding does not work properly on igb +---------------------------------------------------- + +**Description**: + For igb devices rte_eth_flow_ctrl_set does not work as expected. + Pause frames are always forwarded on igb, regardless of the ``RFCE``, ``MPMCF`` and ``DPF`` registers. + +**Implication**: + Pause frames will never be rejected by the host on 1G NICs and they will always be forwarded. + +**Resolution/Workaround**: + There is no workaround available. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Poll Mode Driver (PMD). + + +In packets provided by the PMD, some flags are missing +------------------------------------------------------ + +**Description**: + In packets provided by the PMD, some flags are missing. + The application does not have access to information provided by the hardware + (packet is broadcast, packet is multicast, packet is IPv4 and so on). + +**Implication**: + The ``ol_flags`` field in the ``rte_mbuf`` structure is not correct and should not be used. + +**Resolution/Workaround**: + The application has to parse the Ethernet header itself to get the information, which is slower. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Poll Mode Driver (PMD). + +The rte_malloc library is not fully implemented +----------------------------------------------- + +**Description**: + The ``rte_malloc`` library is not fully implemented. + +**Implication**: + All debugging features of rte_malloc library described in architecture documentation are not yet implemented. + +**Resolution/Workaround**: + No workaround available. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + ``rte_malloc``. + + +HPET reading is slow +-------------------- + +**Description**: + Reading the HPET chip is slow. + +**Implication**: + An application that calls ``rte_get_hpet_cycles()`` or ``rte_timer_manage()`` runs slower. + +**Resolution/Workaround**: + The application should not call these functions too often in the main loop. + An alternative is to use the TSC register through ``rte_rdtsc()`` which is faster, + but specific to an lcore and is a cycle reference, not a time reference. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Environment Abstraction Layer (EAL). + + +HPET timers do not work on the Osage customer reference platform +---------------------------------------------------------------- + +**Description**: + HPET timers do not work on the Osage customer reference platform which includes an Intel® Xeon® processor 5500 + series processor) using the released BIOS from Intel. + +**Implication**: + On Osage boards, the implementation of the ``rte_delay_us()`` function must be changed to not use the HPET timer. + +**Resolution/Workaround**: + This can be addressed by building the system with the ``CONFIG_RTE_LIBEAL_USE_HPET=n`` + configuration option or by using the ``--no-hpet`` EAL option. + +**Affected Environment/Platform**: + The Osage customer reference platform. + Other vendor platforms with Intel® Xeon® processor 5500 series processors should + work correctly, provided the BIOS supports HPET. + +**Driver/Module**: + ``lib/librte_eal/common/include/rte_cycles.h`` + + +Not all variants of supported NIC types have been used in testing +----------------------------------------------------------------- + +**Description**: + The supported network interface cards can come in a number of variants with different device ID's. + Not all of these variants have been tested with the DPDK. + + The NIC device identifiers used during testing: + + * Intel® Ethernet Controller XL710 for 40GbE QSFP+ [8086:1584] + *

[8086:154a] + * Intel® Ethernet Controller I210 [8086:1533] + +**Implication**: + Risk of issues with untested variants. + +**Resolution/Workaround**: + Use tested NIC variants. For those supported Ethernet controllers, additional device + IDs may be added to the software if required. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Poll-mode drivers + + +Multi-process sample app requires exact memory mapping +------------------------------------------------------ + +**Description**: + The multi-process example application assumes that + it is possible to map the hugepage memory to the same virtual addresses in client and server applications. + Occasionally, very rarely with 64-bit, this does not occur and a client application will fail on startup. + The Linux "address-space layout randomization" security feature can sometimes cause this to occur. + +**Implication**: + A multi-process client application fails to initialize. + +**Resolution/Workaround**: + See the "Multi-process Limitations" section in the DPDK Programmer's Guide for more information. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Multi-process example application + + +Packets are not sent by the 1 GbE/10 GbE SR-IOV driver when the source MAC is not the MAC assigned to the VF NIC +---------------------------------------------------------------------------------------------------------------- + +**Description**: + The 1 GbE/10 GbE SR-IOV driver can only send packets when the Ethernet header's source MAC address is the same as + that of the VF NIC. + The reason for this is that the Linux ``ixgbe`` driver module in the host OS has its anti-spoofing feature enabled. + +**Implication**: + Packets sent using the 1 GbE/10 GbE SR-IOV driver must have the source MAC address correctly set to that of the VF NIC. + Packets with other source address values are dropped by the NIC if the application attempts to transmit them. + +**Resolution/Workaround**: + Configure the Ethernet source address in each packet to match that of the VF NIC. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + 1 GbE/10 GbE VF Poll Mode Driver (PMD). + + +SR-IOV drivers do not fully implement the rte_ethdev API +-------------------------------------------------------- + +**Description**: + The SR-IOV drivers only supports the following rte_ethdev API functions: + + * rte_eth_dev_configure() + * rte_eth_tx_queue_setup() + * rte_eth_rx_queue_setup() + * rte_eth_dev_info_get() + * rte_eth_dev_start() + * rte_eth_tx_burst() + * rte_eth_rx_burst() + * rte_eth_dev_stop() + * rte_eth_stats_get() + * rte_eth_stats_reset() + * rte_eth_link_get() + * rte_eth_link_get_no_wait() + +**Implication**: + Calling an unsupported function will result in an application error. + +**Resolution/Workaround**: + Do not use other rte_ethdev API functions in applications that use the SR-IOV drivers. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + VF Poll Mode Driver (PMD). + + +PMD does not work with --no-huge EAL command line parameter +----------------------------------------------------------- + +**Description**: + Currently, the DPDK does not store any information about memory allocated by ``malloc()` (for example, NUMA node, + physical address), hence PMD drivers do not work when the ``--no-huge`` command line parameter is supplied to EAL. + +**Implication**: + Sending and receiving data with PMD will not work. + +**Resolution/Workaround**: + Use huge page memory or use VFIO to map devices. + +**Affected Environment/Platform**: + Systems running the DPDK on Linux + +**Driver/Module**: + Poll Mode Driver (PMD). + + +Some hardware off-load functions are not supported by the VF Driver +------------------------------------------------------------------- + +**Description**: + Currently, configuration of the following items is not supported by the VF driver: + + * IP/UDP/TCP checksum offload + * Jumbo Frame Receipt + * HW Strip CRC + +**Implication**: + Any configuration for these items in the VF register will be ignored. + The behavior is dependent on the current PF setting. + +**Resolution/Workaround**: + For the PF (Physical Function) status on which the VF driver depends, there is an option item under PMD in the + config file. + For others, the VF will keep the same behavior as PF setting. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + VF (SR-IOV) Poll Mode Driver (PMD). + + +Kernel crash on IGB port unbinding +---------------------------------- + +**Description**: + Kernel crash may occur when unbinding 1G ports from the igb_uio driver, on 2.6.3x kernels such as shipped + with Fedora 14. + +**Implication**: + Kernel crash occurs. + +**Resolution/Workaround**: + Use newer kernels or do not unbind ports. + +**Affected Environment/Platform**: + 2.6.3x kernels such as shipped with Fedora 14 + +**Driver/Module**: + IGB Poll Mode Driver (PMD). + + +Twinpond and Ironpond NICs do not report link status correctly +-------------------------------------------------------------- + +**Description**: + Twin Pond/Iron Pond NICs do not bring the physical link down when shutting down the port. + +**Implication**: + The link is reported as up even after issuing ``shutdown`` command unless the cable is physically disconnected. + +**Resolution/Workaround**: + None. + +**Affected Environment/Platform**: + Twin Pond and Iron Pond NICs + +**Driver/Module**: + Poll Mode Driver (PMD). + + +Discrepancies between statistics reported by different NICs +----------------------------------------------------------- + +**Description**: + Gigabit Ethernet devices from Intel include CRC bytes when calculating packet reception statistics regardless + of hardware CRC stripping state, while 10-Gigabit Ethernet devices from Intel do so only when hardware CRC + stripping is disabled. + +**Implication**: + There may be a discrepancy in how different NICs display packet reception statistics. + +**Resolution/Workaround**: + None + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Poll Mode Driver (PMD). + + +Error reported opening files on DPDK initialization +--------------------------------------------------- + +**Description**: + On DPDK application startup, errors may be reported when opening files as part of the initialization process. + This occurs if a large number, for example, 500 or more, or if hugepages are used, due to the per-process + limit on the number of open files. + +**Implication**: + The DPDK application may fail to run. + +**Resolution/Workaround**: + If using 2 MB hugepages, consider switching to a fewer number of 1 GB pages. + Alternatively, use the ``ulimit`` command to increase the number of files which can be opened by a process. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Environment Abstraction Layer (EAL). + + +Intel® QuickAssist Technology sample application does not work on a 32-bit OS on Shumway +---------------------------------------------------------------------------------------- + +**Description**: + The Intel® Communications Chipset 89xx Series device does not fully support NUMA on a 32-bit OS. + Consequently, the sample application cannot work properly on Shumway, since it requires NUMA on both nodes. + +**Implication**: + The sample application cannot work in 32-bit mode with emulated NUMA, on multi-socket boards. + +**Resolution/Workaround**: + There is no workaround available. + +**Affected Environment/Platform**: + Shumway + +**Driver/Module**: + All. + + +Differences in how different Intel NICs handle maximum packet length for jumbo frame +------------------------------------------------------------------------------------ + +**Description**: + 10 Gigabit Ethernet devices from Intel do not take VLAN tags into account when calculating packet size + while Gigabit Ethernet devices do so for jumbo frames. + +**Implication**: + When receiving packets with VLAN tags, the actual maximum size of useful payload that Intel Gigabit Ethernet + devices are able to receive is 4 bytes (or 8 bytes in the case of packets with extended VLAN tags) less than + that of Intel 10 Gigabit Ethernet devices. + +**Resolution/Workaround**: + Increase the configured maximum packet size when using Intel Gigabit Ethernet devices. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Poll Mode Driver (PMD). + + +Binding PCI devices to igb_uio fails on Linux kernel 3.9 when more than one device is used +------------------------------------------------------------------------------------------ + +**Description**: + A known bug in the uio driver included in Linux kernel version 3.9 prevents more than one PCI device to be + bound to the igb_uio driver. + +**Implication**: + The Poll Mode Driver (PMD) will crash on initialization. + +**Resolution/Workaround**: + Use earlier or later kernel versions, or apply the following + `patch `_. + +**Affected Environment/Platform**: + Linux systems with kernel version 3.9 + +**Driver/Module**: + igb_uio module + + +GCC might generate Intel® AVX instructions for processors without Intel® AVX support +------------------------------------------------------------------------------------ + +**Description**: + When compiling DPDK (and any DPDK app), gcc may generate Intel® AVX instructions, even when the + processor does not support Intel® AVX. + +**Implication**: + Any DPDK app might crash while starting up. + +**Resolution/Workaround**: + Either compile using icc or set ``EXTRA_CFLAGS='-O3'`` prior to compilation. + +**Affected Environment/Platform**: + Platforms which processor does not support Intel® AVX. + +**Driver/Module**: + Environment Abstraction Layer (EAL). + +Ethertype filter could receive other packets (non-assigned) in Niantic +---------------------------------------------------------------------- + +**Description**: + On Intel® Ethernet Controller 82599EB When Ethertype filter (priority enable) was set, unmatched packets also + could be received on the assigned queue, such as ARP packets without 802.1q tags or with the user priority not + equal to set value. + Launch the testpmd by disabling RSS and with multiply queues, then add the ethertype filter like the following + and then start forwarding:: + + add_ethertype_filter 0 ethertype 0x0806 priority enable 3 queue 2 index 1 + + When sending ARP packets without 802.1q tag and with user priority as non-3 by tester, all the ARP packets can + be received on the assigned queue. + +**Implication**: + The user priority comparing in Ethertype filter cannot work probably. + It is a NIC's issue due to the following: "In fact, ETQF.UP is not functional, and the information will + be added in errata of 82599 and X540." + +**Resolution/Workaround**: + None + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Poll Mode Driver (PMD). + + +Cannot set link speed on Intel® 40G Ethernet controller +------------------------------------------------------- + +**Description**: + On Intel® 40G Ethernet Controller you cannot set the link to specific speed. + +**Implication**: + The link speed cannot be changed forcibly, though it can be configured by application. + +**Resolution/Workaround**: + None + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Poll Mode Driver (PMD). + + +Devices bound to igb_uio with VT-d enabled do not work on Linux kernel 3.15-3.17 +-------------------------------------------------------------------------------- + +**Description**: + When VT-d is enabled (``iommu=pt intel_iommu=on``), devices are 1:1 mapped. + In the Linux kernel unbinding devices from drivers removes that mapping which result in IOMMU errors. + Introduced in Linux `kernel 3.15 commit + `_, + solved in Linux `kernel 3.18 commit + `_. + +**Implication**: + Devices will not be allowed to access memory, resulting in following kernel errors:: + + dmar: DRHD: handling fault status reg 2 + dmar: DMAR:[DMA Read] Request device [02:00.0] fault addr a0c58000 + DMAR:[fault reason 02] Present bit in context entry is clear + +**Resolution/Workaround**: + Use earlier or later kernel versions, or avoid driver binding on boot by blacklisting the driver modules. + I.e., in the case of ``ixgbe``, we can pass the kernel command line option: ``modprobe.blacklist=ixgbe``. + This way we do not need to unbind the device to bind it to igb_uio. + +**Affected Environment/Platform**: + Linux systems with kernel versions 3.15 to 3.17. + +**Driver/Module**: + ``igb_uio`` module. + + +VM power manager may not work on systems with more than 64 cores +---------------------------------------------------------------- + +**Description**: + When using VM power manager on a system with more than 64 cores, VM(s) should not use cores 64 or higher. + +**Implication**: + VM power manager should not be used with VM(s) that are using cores 64 or above. + +**Resolution/Workaround**: + Do not use cores 64 or above. + +**Affected Environment/Platform**: + Platforms with more than 64 cores. + +**Driver/Module**: + VM power manager application. + + +DPDK may not build on some Intel CPUs using clang < 3.7.0 +--------------------------------------------------------- + +**Description**: + When compiling DPDK with an earlier version than 3.7.0 of clang, CPU flags are not detected on some Intel platforms + such as Intel Broadwell/Skylake (and possibly future CPUs), and therefore compilation fails due to missing intrinsics. + +**Implication**: + DPDK will not build when using a clang version < 3.7.0. + +**Resolution/Workaround**: + Use clang 3.7.0 or higher, or gcc. + +**Affected Environment/Platform**: + Platforms with Intel Broadwell/Skylake using an old clang version. + +**Driver/Module**: + Environment Abstraction Layer (EAL). + + +The last EAL argument is replaced by the program name in argv[] +--------------------------------------------------------------- + +**Description**: + The last EAL argument is replaced by program name in ``argv[]`` after ``eal_parse_args`` is called. + This is the intended behavior but it causes the pointer to the last EAL argument to be lost. + +**Implication**: + If the last EAL argument in ``argv[]`` is generated by a malloc function, changing it will cause memory + issues when freeing the argument. + +**Resolution/Workaround**: + An application should not consider the value in ``argv[]`` as unchanged. + +**Affected Environment/Platform**: + ALL. + +**Driver/Module**: + Environment Abstraction Layer (EAL). + + +I40e VF may not receive packets in the promiscuous mode +------------------------------------------------------- + +**Description**: + Promiscuous mode is not supported by the DPDK i40e VF driver when using the + i40e Linux kernel driver as host driver. + +**Implication**: + The i40e VF does not receive packets when the destination MAC address is unknown. + +**Resolution/Workaround**: + Use a explicit destination MAC address that matches the VF. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Poll Mode Driver (PMD). + + +uio pci generic module bind failed in X710/XL710/XXV710 +------------------------------------------------------- + +**Description**: + The ``uio_pci_generic`` module is not supported by XL710, since the errata of XL710 + states that the Interrupt Status bit is not implemented. The errata is the item #71 + from the `xl710 controller spec + `_. + The hw limitation is the same as other X710/XXV710 NICs. + +**Implication**: + When use ``--bind=uio_pci_generic``, the ``uio_pci_generic`` module probes device and check the Interrupt + Status bit. Since it is not supported by X710/XL710/XXV710, it return a *failed* value. The statement + that these products don’t support INTx masking, is indicated in the related `linux kernel commit + `_. + +**Resolution/Workaround**: + Do not bind the ``uio_pci_generic`` module in X710/XL710/XXV710 NICs. + +**Affected Environment/Platform**: + All. + +**Driver/Module**: + Poll Mode Driver (PMD). + + +virtio tx_burst() function cannot do TSO on shared packets +---------------------------------------------------------- + +**Description**: + The standard TX function of virtio driver does not manage shared + packets properly when doing TSO. These packets should be read-only + but the driver modifies them. + + When doing TSO, the virtio standard expects that the L4 checksum is + set to the pseudo header checksum in the packet data, which is + different than the DPDK API. The driver patches the L4 checksum to + conform to the virtio standard, but this solution is invalid when + dealing with shared packets (clones), because the packet data should + not be modified. + +**Implication**: + In this situation, the shared data will be modified by the driver, + potentially causing race conditions with the other users of the mbuf + data. + +**Resolution/Workaround**: + The workaround in the application is to ensure that the network + headers in the packet data are not shared. + +**Affected Environment/Platform**: + Virtual machines running a virtio driver. + +**Driver/Module**: + Poll Mode Driver (PMD). + + +igb uio legacy mode can not be used in X710/XL710/XXV710 +-------------------------------------------------------- + +**Description**: + X710/XL710/XXV710 NICs lack support for indicating INTx is asserted via the interrupt + bit in the PCI status register. Linux delected them from INTx support table. The related + `commit `_. + +**Implication**: + When insmod ``igb_uio`` with ``intr_mode=legacy`` and test link status interrupt. Since + INTx interrupt is not supported by X710/XL710/XXV710, it will cause Input/Output error + when reading file descriptor. + +**Resolution/Workaround**: + Do not bind ``igb_uio`` with legacy mode in X710/XL710/XXV710 NICs, or do not use kernel + version >4.7 when you bind ``igb_uio`` with legacy mode. + +**Affected Environment/Platform**: + ALL. + +**Driver/Module**: + Poll Mode Driver (PMD). + + +igb_uio can not be used when running l3fwd-power +------------------------------------------------ + +**Description**: + Link Status Change(LSC) interrupt and packet receiving interrupt are all enabled in l3fwd-power + APP. Because of UIO only support one interrupt, so these two kinds of interrupt need to share + one, and the receiving interrupt have the higher priority, so can't get the right link status. + +**Implication**: + When insmod ``igb_uio`` and running l3fwd-power APP, link status getting doesn't work properly. + +**Resolution/Workaround**: + Use vfio-pci when LSC and packet receiving interrupt enabled. + +**Affected Environment/Platform**: + ALL. + +**Driver/Module**: + ``igb_uio`` module. diff --git a/dpdk/doc/guides/rel_notes/rel_description.rst b/dpdk/doc/guides/rel_notes/rel_description.rst new file mode 100644 index 0000000..8f28556 --- /dev/null +++ b/dpdk/doc/guides/rel_notes/rel_description.rst @@ -0,0 +1,12 @@ +..

It means + the CLIs should be used on the PF, but some of their effects will be shown on the VF. + The forwarding of E-tag packets based on GRP and E-CID_base will have an effect + on the PF. Theoretically, the E-tag packets can be forwarded to any pool/queue + but normally we'd like to forward the packets to the pools/queues belonging + to the VFs. And E-tag insertion and stripping will have an effect on VFs. When + a VF receives E-tag packets it should strip the E-tag. When the VF transmits + packets, it should insert the E-tag. Both actions can be offloaded. + + When we want to use this E-tag support feature, the forwarding should be + enabled to forward the packets received by the PF to the indicated VFs. And insertion + and stripping should be enabled for VFs to offload the effort to hardware. + + Features added: + + * Support E-tag offloading of insertion and stripping. + * Support Forwarding E-tag packets to pools based on + GRP and E-CID_base. + +* **Added support for VxLAN and NVGRE checksum off-load on X550.** + + * Added support for VxLAN and NVGRE RX/TX checksum off-load on + X550. RX/TX checksum off-load is provided on both inner and + outer IP header and TCP header. + * Added functions to support VxLAN port configuration. The + default VxLAN port number is 4789 but this can be updated + programmatically. + +* **Added support for new X550EM_a devices.** + + Added support for new X550EM_a devices and their MAC types, X550EM_a and X550EM_a_vf. + Updated the relevant PMD to use the new devices and MAC types. + +* **Added x550em_x V2 device support.** + + Added support for x550em_x V2 device. Only x550em_x V1 was supported before. + A mask for V1 and V2 is defined and used to support both. + +* **Supported link speed auto-negotiation on X550EM_X** + + Normally the auto-negotiation is supported by firmware and software doesn't care about + it. But on x550em_x, firmware doesn't support auto-negotiation. As the ports of x550em_x + are 10GbE, if we connect the port with a peer which is 1GbE, the link will always + be down. + We added the support for auto-negotiation by software to avoid this link down issue. + +* **Added software-firmware sync on X550EM_a.** + + Added support for software-firmware sync for resource sharing. + Use the PHY token, shared between software-firmware for PHY access on X550EM_a. + +* **Updated the i40e base driver.** + + The i40e base driver was updated with changes including the + following: + + * Use RX control AQ commands to read/write RX control registers. + * Add new X722 device IDs, and removed X710 one was never used. + * Expose registers for HASH/FD input set configuring. + +* **Enabled PCI extended tag for i40e.** + + Enabled extended tag for i40e by checking and writing corresponding PCI config + space bytes, to boost the performance. + The legacy method of reading/writing sysfile supported by kernel module igb_uio + is now deprecated. + +* **Added i40e support for setting mac addresses.** + +* **Added dump of i40e registers and EEPROM.** + +* **Supported ether type setting of single and double VLAN for i40e** + +* **Added VMDQ DCB mode in i40e.** + + Added support for DCB in VMDQ mode to i40e driver. + +* **Added i40e VEB switching support.** + +* **Added Flow director enhancements in i40e.** + +* **Added PF reset event reporting in i40e VF driver.** + +* **Added fm10k RX interrupt support.** + +* **Optimized fm10k TX.** + + Optimized fm10k TX by freeing multiple mbufs at a time. + +* **Handled error flags in fm10k vector RX.** + + Parse error flags in RX descriptor and set error bits in mbuf with vector instructions. + +* **Added fm10k FTAG based forwarding support.** + +* **Added mlx5 flow director support.** + + Added flow director support (``RTE_FDIR_MODE_PERFECT`` and + ``RTE_FDIR_MODE_PERFECT_MAC_VLAN``). + + Only available with Mellanox OFED >= 3.2. + +* **Added mlx5 RX VLAN stripping support.** + + Added support for RX VLAN stripping. + + Only available with Mellanox OFED >= 3.2. + +* **Added mlx5 link up/down callbacks.** + + Implemented callbacks to bring link up and down. + +* **Added mlx5 support for operation in secondary processes.** + + Implemented TX support in secondary processes (like mlx4). + +* **Added mlx5 RX CRC stripping configuration.** + + Until now, CRC was always stripped. It can now be configured. + + Only available with Mellanox OFED >= 3.2. + +* **Added mlx5 optional packet padding by HW.** + + Added an option to make PCI bus transactions rounded to a multiple of a + cache line size for better alignment. + + Only available with Mellanox OFED >= 3.2. + +* **Added mlx5 TX VLAN insertion support.** + + Added support for TX VLAN insertion. + + Only available with Mellanox OFED >= 3.2. + +* **Changed szedata2 driver type from vdev to pdev.** + + Previously szedata2 device had to be added by ``--vdev`` option. + Now szedata2 PMD recognizes the device automatically during EAL + initialization. + +* **Added szedata2 functions for setting link up/down.** + +* **Added szedata2 promiscuous and allmulticast modes.** + +* **Added af_packet dynamic removal function.** + + An af_packet device can now be detached using the API, like other PMD devices. + +* **Increased number of next hops for LPM IPv4 to 2^24.** + + The ``next_hop`` field has been extended from 8 bits to 24 bits for IPv4. + +* **Added support of SNOW 3G (UEA2 and UIA2) for Intel Quick Assist devices.** + + Enabled support for the SNOW 3G wireless algorithm for Intel Quick Assist devices. + Support for cipher-only and hash-only is also provided + along with algorithm-chaining operations. + +* **Added SNOW3G SW PMD.** + + A new Crypto PMD has been added, which provides SNOW 3G UEA2 ciphering + and SNOW3G UIA2 hashing. + +* **Added AES GCM PMD.** + + Added new Crypto PMD to support AES-GCM authenticated encryption and + authenticated decryption in software. + +* **Added NULL Crypto PMD** + + Added new Crypto PMD to support null crypto operations in software. + +* **Improved IP Pipeline Application.** + + The following features have been added to ip_pipeline application; + + * Added CPU utilization measurement and idle cycle rate computation. + * Added link identification support through existing port-mask option or by + specifying PCI device in every LINK section in the configuration file. + * Added load balancing support in passthrough pipeline. + +* **Added IPsec security gateway example.** + + Added a new application implementing an IPsec Security Gateway. + + +Resolved Issues +--------------- + +Drivers +~~~~~~~ + +* **ethdev: Fixed overflow for 100Gbps.** + + 100Gbps in Mbps (100000) was exceeding the 16-bit max value of ``link_speed`` + in ``rte_eth_link``. + +* **ethdev: Fixed byte order consistency between fdir flow and mask.** + + Fixed issue in ethdev library where the structure for setting + fdir's mask and flow entry was not consistent in byte ordering. + +* **cxgbe: Fixed crash due to incorrect size allocated for RSS table.** + + Fixed a segfault that occurs when accessing part of port 0's RSS + table that gets overwritten by subsequent port 1's part of the RSS + table due to incorrect size allocated for each entry in the table. + +* **cxgbe: Fixed setting wrong device MTU.** + + Fixed an incorrect device MTU being set due to the Ethernet header and + CRC lengths being added twice. + +* **ixgbe: Fixed zeroed VF mac address.** + + Resolved an issue where the VF MAC address is zeroed out in cases where the VF + driver is loaded while the PF interface is down. + The solution is to only set it when we get an ACK from the PF. + +* **ixgbe: Fixed setting flow director flag twice.** + + Resolved an issue where packets were being dropped when switching to perfect + filters mode. + +* **ixgbe: Set MDIO speed after MAC reset.** + + The MDIO clock speed must be reconfigured after the MAC reset. The MDIO clock + speed becomes invalid, therefore the driver reads invalid PHY register values. + The driver now set the MDIO clock speed prior to initializing PHY ops and + again after the MAC reset. + +* **ixgbe: Fixed maximum number of available TX queues.** + + In IXGBE, the maximum number of TX queues varies depending on the NIC operating + mode. This was not being updated in the device information, providing + an incorrect number in some cases. + +* **i40e: Generated MAC address for each VFs.** + + It generates a MAC address for each VFs during PF host initialization, + and keeps the VF MAC address the same among different VF launch. + +* **i40e: Fixed failure of reading/writing RX control registers.** + + Fixed i40e issue of failing to read/write rx control registers when + under stress with traffic, which might result in application launch + failure. + +* **i40e: Enabled vector driver by default.** + + Previously, vector driver was disabled by default as it couldn't fill packet type + info for l3fwd to work well. Now there is an option for l3fwd to analyze + the packet type so the vector driver is enabled by default. + +* **i40e: Fixed link info of VF.** + + Previously, the VF's link speed stayed at 10GbE and status always was up. + It did not change even when the physical link's status changed. + Now this issue is fixed to make VF's link info consistent with physical link. + +* **mlx5: Fixed possible crash during initialization.** + + A crash could occur when failing to allocate private device context. + +* **mlx5: Added port type check.** + + Added port type check to prevent port initialization on non-Ethernet link layers and + to report an error. + +* **mlx5: Applied VLAN filtering to broadcast and IPv6 multicast flows.** + + Prevented reception of multicast frames outside of configured VLANs. + +* **mlx5: Fixed RX checksum offload in non L3/L4 packets.** + + Fixed report of bad checksum for packets of unknown type. + +* **aesni_mb: Fixed wrong return value when creating a device.** + + The ``cryptodev_aesni_mb_init()`` function was returning the device id of the device created, + instead of 0 (on success) that ``rte_eal_vdev_init()`` expects. + This made it impossible to create more than one aesni_mb device + from the command line. + +* **qat: Fixed AES GCM decryption.** + + Allowed AES GCM on the cryptodev API, but in some cases gave invalid results + due to incorrect IV setting. + + +Libraries +~~~~~~~~~ + +* **hash: Fixed CRC32c hash computation for non multiple of 4 bytes sizes.** + + Fix crc32c hash functions to return a valid crc32c value for data lengths + not a multiple of 4 bytes. + +* **hash: Fixed hash library to support multi-process mode.** + + Fix hash library to support multi-process mode, using a jump table, + instead of storing a function pointer to the key compare function. + Multi-process mode only works with the built-in compare functions, + however a custom compare function (not in the jump table) can only + be used in single-process mode. + +* **hash: Fixed return value when allocating an existing hash table.** + + Changed the ``rte_hash*_create()`` functions to return ``NULL`` and set + ``rte_errno`` to ``EEXIST`` when the object name already exists. This is + the behavior described in the API documentation in the header file. + The previous behavior was to return a pointer to the existing object in + that case, preventing the caller from knowing if the object had to be freed + or not. + +* **lpm: Fixed return value when allocating an existing object.** + + Changed the ``rte_lpm*_create()`` functions to return ``NULL`` and set + ``rte_errno`` to ``EEXIST`` when the object name already exists. This is + the behavior described in the API documentation in the header file. + The previous behavior was to return a pointer to the existing object in + that case, preventing the caller from knowing if the object had to be freed + or not. + +* **librte_port: Fixed segmentation fault for ring and ethdev writer nodrop.** + + Fixed core dump issue on txq and swq when dropless is set to yes. + + +Examples +~~~~~~~~ + +* **l3fwd-power: Fixed memory leak for non-IP packet.** + + Fixed issue in l3fwd-power where, on receiving packets of types + other than IPv4 or IPv6, the mbuf was not released, and caused + a memory leak. + +* **l3fwd: Fixed using packet type blindly.** + + l3fwd makes use of packet type information without querying if devices or PMDs + really set it. For those devices that don't set ptypes, add an option to parse it. + +* **examples/vhost: Fixed frequent mbuf allocation failure.** + + The vhost-switch often fails to allocate mbuf when dequeue from vring because it + wrongly calculates the number of mbufs needed. + + +API Changes +----------- + +* The ethdev statistics counter ``imissed`` is considered to be independent of ``ierrors``. + All drivers are now counting the missed packets only once, i.e. drivers will + not increment ierrors anymore for missed packets. + +* The ethdev structure ``rte_eth_dev_info`` was changed to support device + speed capabilities. + +* The ethdev structures ``rte_eth_link`` and ``rte_eth_conf`` were changed to + support the new link API. + +* The functions ``rte_eth_dev_udp_tunnel_add`` and ``rte_eth_dev_udp_tunnel_delete`` + have been renamed into ``rte_eth_dev_udp_tunnel_port_add`` and + ``rte_eth_dev_udp_tunnel_port_delete``. + +* The ``outer_mac`` and ``inner_mac`` fields in structure + ``rte_eth_tunnel_filter_conf`` are changed from pointer to struct in order + to keep code's readability. + +* The fields in ethdev structure ``rte_eth_fdir_masks`` were changed + to be in big endian. + +* A parameter ``vlan_type`` has been added to the function + ``rte_eth_dev_set_vlan_ether_type``. + +* The af_packet device init function is no longer public. The device should be attached + via the API. + +* The LPM ``next_hop`` field is extended from 8 bits to 24 bits for IPv4 + while keeping ABI compatibility. + +* A new ``rte_lpm_config`` structure is used so the LPM library will allocate + exactly the amount of memory which is necessary to hold application’s rules. + The previous ABI is kept for compatibility. + +* The prototype for the pipeline input port, output port and table action + handlers are updated: the pipeline parameter is added, + the packets mask parameter has been either removed or made input-only. + + +ABI Changes +----------- + +* The RETA entry size in ``rte_eth_rss_reta_entry64`` has been increased + from 8-bit to 16-bit. + +* The ethdev flow director structure ``rte_eth_fdir_flow`` structure was + changed. New fields were added to extend flow director's input set. + +* The cmdline buffer size has been increase from 256 to 512. + + +Shared Library Versions +----------------------- + +The libraries prepended with a plus sign were incremented in this version. + +.. code-block:: diff + + + libethdev.so.3 + librte_acl.so.2 + librte_cfgfile.so.2 + + librte_cmdline.so.2 + librte_distributor.so.1 + librte_eal.so.2 + librte_hash.so.2 + librte_ip_frag.so.1 + librte_ivshmem.so.1 + librte_jobstats.so.1 + librte_kni.so.2 + librte_kvargs.so.1 + librte_lpm.so.2 + librte_mbuf.so.2 + librte_mempool.so.1 + librte_meter.so.1 + + librte_pipeline.so.3 + librte_pmd_bond.so.1 + librte_pmd_ring.so.2 + librte_port.so.2 + librte_power.so.1 + librte_reorder.so.1 + librte_ring.so.1 + librte_sched.so.1 + librte_table.so.2 + librte_timer.so.1 + librte_vhost.so.2 + + +Tested Platforms +---------------- + +#.

The error seen by the + user is as similar to the following:: + + EAL: pci_map_resource(): + + cannot mmap(39, 0x7f1c51800000, 0x100000, 0x0): + Invalid argument (0xffffffffffffffff) + + The ``CONFIG_IO_STRICT_DEVMEM`` kernel option was introduced in Linux v4.5. + + The issues was resolve by updating ``igb_uio`` to stop reserving PCI memory + resources. From the kernel point of view the iomem region looks like idle + and mmap works again. This matches the ``uio_pci_generic`` usage. + + +Drivers +~~~~~~~ + +* **i40e: Fixed vlan stripping from inner header.** + + Previously, for tunnel packets, such as VXLAN/NVGRE, the vlan + tags of the inner header will be stripped without putting vlan + info to descriptor. + Now this issue is fixed by disabling vlan stripping from inner header. + +* **i40e: Fixed the type issue of a single VLAN type.** + + Currently, if a single VLAN header is added in a packet, it's treated + as inner VLAN. But generally, a single VLAN header is treated as the + outer VLAN header. + This issue is fixed by changing corresponding register for single VLAN. + +* **enic: Fixed several issues when stopping then restarting ports and queues.** + + Fixed several crashes related to stopping then restarting ports and queues. + Fixed possible crash when re-configuring the number of Rx queue descriptors. + +* **enic: Fixed Rx data mis-alignment if mbuf data offset modified.** + + Fixed possible Rx corruption when mbufs were returned to a pool with data + offset other than RTE_PKTMBUF_HEADROOM. + +* **enic: Fixed Tx IP/UDP/TCP checksum offload and VLAN insertion.** + +* **enic: Fixed Rx error and missed counters.** + + +Libraries +~~~~~~~~~ + +* **mbuf: Fixed refcnt update when detaching.** + + Fix the ``rte_pktmbuf_detach()`` function to decrement the direct mbuf's + reference counter. The previous behavior was not to affect the reference + counter. This lead to a memory leak of the direct mbuf. + + +Examples +~~~~~~~~ + + +Other +~~~~~ + + +Known Issues +------------ + +.. This section should contain new known issues in this release. Sample format: + + * **Add title in present tense with full stop.** + + Add a short 1-2 sentence description of the known issue in the present + tense.

Use fixed width + quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past tense. + +* The following counters are removed from the ``rte_eth_stats`` structure: + + * ``ibadcrc`` + * ``ibadlen`` + * ``imcasts`` + * ``fdirmatch`` + * ``fdirmiss`` + * ``tx_pause_xon`` + * ``rx_pause_xon`` + * ``tx_pause_xoff`` + * ``rx_pause_xoff`` + +* The extended statistics are fetched by ids with ``rte_eth_xstats_get`` + after a lookup by name ``rte_eth_xstats_get_names``. + +* The function ``rte_eth_dev_info_get`` fill the new fields ``nb_rx_queues`` + and ``nb_tx_queues`` in the structure ``rte_eth_dev_info``. + +* The vhost function ``rte_vring_available_entries`` is renamed to + ``rte_vhost_avail_entries``. + +* All existing vhost APIs and callbacks with ``virtio_net`` struct pointer + as the parameter have been changed due to the ABI refactoring described + below. It is replaced by ``int vid``. + +* The function ``rte_vhost_enqueue_burst`` no longer supports concurrent enqueuing + packets to the same queue. + +* The function ``rte_eth_dev_set_mtu`` adds a new return value ``-EBUSY``, which + indicates the operation is forbidden because the port is running. + +* The script ``dpdk_nic_bind.py`` is renamed to ``dpdk-devbind.py``. + And the script ``setup.sh`` is renamed to ``dpdk-setup.sh``. + + +ABI Changes +----------- + +.. * Add a short 1-2 sentence description of the ABI change that was announced in + the previous releases and made in this release. Use fixed width quotes for + ``rte_function_names`` or ``rte_struct_names``. Use the past tense. + +* The ``rte_port_source_params`` structure has new fields to support PCAP files. + It was already in release 16.04 with ``RTE_NEXT_ABI`` flag. + +* The ``rte_eth_dev_info`` structure has new fields ``nb_rx_queues`` and ``nb_tx_queues`` + to support the number of queues configured by software. + +* A Vhost ABI refactoring has been made: the ``virtio_net`` structure is no + longer exported directly to the application. Instead, a handle, ``vid``, has + been used to represent this structure internally. + + +Shared Library Versions +----------------------- + +..

This section should contain new features added in this release. Sample format: + + * **Add a title in the past tense with a full stop.** + + Add a short 1-2 sentence description in the past tense. The description + should be enough to allow someone scanning the release notes to understand + the new feature. + + If the feature adds a lot of sub-features you can use a bullet list like this. + + * Added feature foo to do something. + * Enhanced feature bar to do something else. + + Refer to the previous release notes for examples. + + This section is a comment. Make sure to start the actual text at the margin. + + +* **Added software parser for packet type.** + + * Added a new function ``rte_pktmbuf_read()`` to read the packet data from an + mbuf chain, linearizing if required. + * Added a new function ``rte_net_get_ptype()`` to parse an Ethernet packet + in an mbuf chain and retrieve its packet type from software. + * Added new functions ``rte_get_ptype_*()`` to dump a packet type as a string. + +* **Improved offloads support in mbuf.** + + * Added a new function ``rte_raw_cksum_mbuf()`` to process the checksum of + data embedded in an mbuf chain. + * Added new Rx checksum flags in mbufs to describe more states: unknown, + good, bad, or not present (useful for virtual drivers). This modification + was done for IP and L4. + * Added a new Rx LRO mbuf flag, used when packets are coalesced. This + flag indicates that the segment size of original packets is known. + +* **Added vhost-user dequeue zero copy support.** + + The copy in the dequeue path is avoided in order to improve the performance. + In the VM2VM case, the boost is quite impressive. The bigger the packet size, + the bigger performance boost you may get. However, for the VM2NIC case, there + are some limitations, so the boost is not as impressive as the VM2VM case. + It may even drop quite a bit for small packets. + + For that reason, this feature is disabled by default. It can be enabled when + the ``RTE_VHOST_USER_DEQUEUE_ZERO_COPY`` flag is set. Check the VHost section + of the Programming Guide for more information. + +* **Added vhost-user indirect descriptors support.** + + If the indirect descriptor feature is enabled, each packet sent by the guest + will take exactly one slot in the enqueue virtqueue. Without this feature, as in + the current version, even 64 bytes packets take two slots with Virtio PMD on guest + side. + + The main impact is better performance for 0% packet loss use-cases, as it + behaves as if the virtqueue size was enlarged, so more packets can be buffered + in the case of system perturbations. On the downside, small performance degradations + were measured when running micro-benchmarks. + +* **Added vhost PMD xstats.** + + Added extended statistics to vhost PMD from a per port perspective. + +* **Supported offloads with virtio.** + + Added support for the following offloads in virtio: + + * Rx/Tx checksums. + * LRO. + * TSO. + +* **Added virtio NEON support for ARM.** + + Added NEON support for ARM based virtio. + +* **Updated the ixgbe base driver.** + + Updated the ixgbe base driver, including the following changes: + + * Added X550em_a 10G PHY support. + * Added support for flow control auto negotiation for X550em_a 1G PHY. + * Added X550em_a FW ALEF support. + * Increased mailbox version to ``ixgbe_mbox_api_13``. + * Added two MAC operations for Hyper-V support. + +* **Added APIs for VF management to the ixgbe PMD.** + + Eight new APIs have been added to the ixgbe PMD for VF management from the PF. + The declarations for the API's can be found in ``rte_pmd_ixgbe.h``. + +* **Updated the enic driver.** + + * Added update to use interrupt for link status checking instead of polling. + * Added more flow director modes on UCS Blade with firmware version >= 2.0(13e). + * Added full support for MTU update. + * Added support for the ``rte_eth_rx_queue_count`` function. + +* **Updated the mlx5 driver.** + + * Added support for RSS hash results. + * Added several performance improvements. + * Added several bug fixes. + +* **Updated the QAT PMD.** + + The QAT PMD was updated with additional support for: + + * MD5_HMAC algorithm. + * SHA224-HMAC algorithm. + * SHA384-HMAC algorithm. + * GMAC algorithm. + * KASUMI (F8 and F9) algorithm. + * 3DES algorithm. + * NULL algorithm. + * C3XXX device. + * C62XX device. + +* **Added openssl PMD.** + + A new crypto PMD has been added, which provides several ciphering and hashing algorithms. + All cryptography operations use the Openssl library crypto API. + +* **Updated the IPsec example.** + + Updated the IPsec example with the following support: + + * Configuration file support. + * AES CBC IV generation with cipher forward function. + * AES GCM/CTR mode. + +* **Added support for new gcc -march option.** + + The GCC 4.9 ``-march`` option supports the Intel processor code names. + The config option ``RTE_MACHINE`` can be used to pass code names to the compiler via the ``-march`` flag. + + +Resolved Issues +--------------- + +..

This section should contain new known issues in this release. Sample format: + + * **Add title in present tense with full stop.** + + Add a short 1-2 sentence description of the known issue in the present + tense. Add information on any known workarounds. + + This section is a comment. Make sure to start the actual text at the margin. + +* **L3fwd-power app does not work properly when Rx vector is enabled.** + + The L3fwd-power app doesn't work properly with some drivers in vector mode + since the queue monitoring works differently between scalar and vector modes + leading to incorrect frequency scaling. In addition, L3fwd-power application + requires the mbuf to have correct packet type set but in some drivers the + vector mode must be disabled for this. + + Therefore, in order to use L3fwd-power, vector mode should be disabled + via the config file. + +* **Digest address must be supplied for crypto auth operation on QAT PMD.** + + The cryptodev API specifies that if the rte_crypto_sym_op.digest.data field, + and by inference the digest.phys_addr field which points to the same location, + is not set for an auth operation the driver is to understand that the digest + result is located immediately following the region over which the digest is + computed. The QAT PMD doesn't correctly handle this case and reads and writes + to an incorrect location. + + Callers can workaround this by always supplying the digest virtual and + physical address fields in the rte_crypto_sym_op for an auth operation. + + +API Changes +----------- + +.. This section should contain API changes. Sample format: + + * Add a short 1-2 sentence description of the API change. Use fixed width + quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past tense. + + This section is a comment. Make sure to start the actual text at the margin. + +* The driver naming convention has been changed to make them more + consistent. It especially impacts ``--vdev`` arguments. For example + ``eth_pcap`` becomes ``net_pcap`` and ``cryptodev_aesni_mb_pmd`` becomes + ``crypto_aesni_mb``. + + For backward compatibility an alias feature has been enabled to support the + original names. + +* The log history has been removed. + +* The ``rte_ivshmem`` feature (including library and EAL code) has been removed + in 16.11 because it had some design issues which were not planned to be fixed. + +* The ``file_name`` data type of ``struct rte_port_source_params`` and + ``struct rte_port_sink_params`` is changed from ``char *`` to ``const char *``. + +* **Improved device/driver hierarchy and generalized hotplugging.** + + The device and driver relationship has been restructured by introducing generic + classes. This paves the way for having PCI, VDEV and other device types as + instantiated objects rather than classes in themselves. Hotplugging has also + been generalized into EAL so that Ethernet or crypto devices can use the + common infrastructure. + + * Removed ``pmd_type`` as a way of segregation of devices. + * Moved ``numa_node`` and ``devargs`` into ``rte_driver`` from + ``rte_pci_driver``. These can now be used by any instantiated object of + ``rte_driver``. + * Added ``rte_device`` class and all PCI and VDEV devices inherit from it + * Renamed devinit/devuninit handlers to probe/remove to make it more + semantically correct with respect to the device <=> driver relationship. + * Moved hotplugging support to EAL. Hereafter, PCI and vdev can use the + APIs ``rte_eal_dev_attach`` and ``rte_eal_dev_detach``. + * Renamed helpers and support macros to make them more synonymous + with their device types + (e.g. ``PMD_REGISTER_DRIVER`` => ``RTE_PMD_REGISTER_PCI``). + * Device naming functions have been generalized from ethdev and cryptodev + to EAL. ``rte_eal_pci_device_name`` has been introduced for obtaining + unique device name from PCI Domain-BDF description. + * Virtual device registration APIs have been added: ``rte_eal_vdrv_register`` + and ``rte_eal_vdrv_unregister``. + + +ABI Changes +----------- + +.. This section should contain ABI changes. Sample format: + + * Add a short 1-2 sentence description of the ABI change that was announced in + the previous releases and made in this release.

This allows for + devices to be represented by buses they are connected to. A new bus can be + added to DPDK by extending the ``rte_bus`` structure and implementing the + scan and probe functions. Once a new bus is registered using the provided + APIs, new devices can be detected and initialized using bus scan and probe + callbacks. + + With this change, devices other than PCI or VDEV type can be represented + in the DPDK framework. + +* **Added generic EAL API for I/O device memory read/write operations.** + + This API introduces 8 bit, 16 bit, 32 bit and 64 bit I/O device + memory read/write operations along with "relaxed" versions. + + Weakly-ordered architectures like ARM need an additional I/O barrier for + device memory read/write access over PCI bus. By introducing the EAL + abstraction for I/O device memory read/write access, the drivers can access + I/O device memory in an architecture-agnostic manner. The relaxed version + does not have an additional I/O memory barrier, which is useful in accessing + the device registers of integrated controllers which is implicitly strongly + ordered with respect to memory access. + +* **Added generic flow API (rte_flow).** + + This API provides a generic means to configure hardware to match specific + ingress or egress traffic, alter its behavior and query related counters + according to any number of user-defined rules. + + In order to expose a single interface with an unambiguous behavior that is + common to all poll-mode drivers (PMDs) the ``rte_flow`` API is slightly + higher-level than the legacy filtering framework, which it encompasses and + supersedes (including all functions and filter types) . + + See the :ref:`Generic flow API ` documentation for more + information. + +* **Added firmware version get API.** + + Added a new function ``rte_eth_dev_fw_version_get()`` to fetch the firmware + version for a given device. + +* **Added APIs for MACsec offload support to the ixgbe PMD.** + + Six new APIs have been added to the ixgbe PMD for MACsec offload support. + The declarations for the APIs can be found in ``rte_pmd_ixgbe.h``. + +* **Added I219 NICs support.** + + Added support for I219 Intel 1GbE NICs. + +* **Added VF Daemon (VFD) for i40e. - EXPERIMENTAL** + + This is an EXPERIMENTAL feature to enhance the capability of the DPDK PF as + many VF management features are not currently supported by the kernel PF + driver. Some new private APIs are implemented directly in the PMD without an + abstraction layer. They can be used directly by some users who have the + need. + + The new APIs to control VFs directly from PF include: + + * Set VF MAC anti-spoofing. + * Set VF VLAN anti-spoofing. + * Set TX loopback. + * Set VF unicast promiscuous mode. + * Set VF multicast promiscuous mode. + * Set VF MTU. + * Get/reset VF stats. + * Set VF MAC address. + * Set VF VLAN stripping. + * Vf VLAN insertion. + * Set VF broadcast mode. + * Set VF VLAN tag. + * Set VF VLAN filter. + + VFD also includes VF to PF mailbox message management from an application. + When the PF receives mailbox messages from the VF the PF should call the + callback provided by the application to know if they're permitted to be + processed. + + As an EXPERIMENTAL feature, please be aware it can be changed or even + removed without prior notice. + +* **Updated the i40e base driver.** + + Updated the i40e base driver, including the following changes: + + * Replace existing legacy ``memcpy()`` calls with ``i40e_memcpy()`` calls. + * Use ``BIT()`` macro instead of bit fields. + * Add clear all WoL filters implementation. + * Add broadcast promiscuous control per VLAN. + * Remove unused ``X722_SUPPORT`` and ``I40E_NDIS_SUPPORT`` macros. + +* **Updated the enic driver.** + + * Set new Rx checksum flags in mbufs to indicate unknown, good or bad checksums. + * Fix set/remove of MAC addresses. Allow up to 64 addresses per device. + * Enable TSO on outer headers. + +* **Added Solarflare libefx-based network PMD.** + + Added a new network PMD which supports Solarflare SFN7xxx and SFN8xxx family + of 10/40 Gbps adapters. + +* **Updated the mlx4 driver.** + + * Addressed a few bugs. + +* **Added support for Mellanox ConnectX-5 adapters (mlx5).** + + Added support for Mellanox ConnectX-5 family of 10/25/40/50/100 Gbps + adapters to the existing mlx5 PMD. + +* **Updated the mlx5 driver.** + + * Improve Tx performance by using vector logic. + * Improve RSS balancing when number of queues is not a power of two. + * Generic flow API support for Ethernet, IPv4, IPv4, UDP, TCP, VLAN and + VXLAN pattern items with DROP and QUEUE actions. + * Support for extended statistics. + * Addressed several data path bugs. + * As of MLNX_OFED 4.0-1.0.1.0, the Toeplitz RSS hash function is not + symmetric anymore for consistency with other PMDs. + +* **virtio-user with vhost-kernel as another exceptional path.** + + Previously, we upstreamed a virtual device, virtio-user with vhost-user as + the backend as a way of enabling IPC (Inter-Process Communication) and user + space container networking. + + Virtio-user with vhost-kernel as the backend is a solution for the exception + path, such as KNI, which exchanges packets with the kernel networking stack. + This solution is very promising in: + + * Maintenance: vhost and vhost-net (kernel) is an upstreamed and extensively + used kernel module. + * Features: vhost-net is designed to be a networking solution, which has + lots of networking related features, like multi-queue, TSO, multi-seg + mbuf, etc. + * Performance: similar to KNI, this solution would use one or more + kthreads to send/receive packets from user space DPDK applications, + which has little impact on user space polling thread (except that + it might enter into kernel space to wake up those kthreads if + necessary). + +* **Added virtio Rx interrupt support.** + + Added a feature to enable Rx interrupt mode for virtio pci net devices as + bound to VFIO (noiommu mode) and driven by virtio PMD. + + With this feature, the virtio PMD can switch between polling mode and + interrupt mode, to achieve best performance, and at the same time save + power. It can work on both legacy and modern virtio devices. In this mode, + each ``rxq`` is mapped with an excluded MSIx interrupt. + + See the :ref:`Virtio Interrupt Mode ` documentation + for more information. + +* **Added ARMv8 crypto PMD.** + + A new crypto PMD has been added, which provides combined mode cryptographic + operations optimized for ARMv8 processors. The driver can be used to enhance + performance in processing chained operations such as cipher + HMAC. + +* **Updated the QAT PMD.** + + The QAT PMD has been updated with additional support for: + + * DES algorithm. + * Scatter-gather list (SGL) support. + +* **Updated the AESNI MB PMD.** + + * The Intel(R) Multi Buffer Crypto for IPsec library used in + AESNI MB PMD has been moved to a new repository, in GitHub. + * Support has been added for single operations (cipher only and + authentication only). + +* **Updated the AES-NI GCM PMD.** + + The AES-NI GCM PMD was migrated from the Multi Buffer library to the ISA-L + library. The migration entailed adding additional support for: + + * GMAC algorithm. + * 256-bit cipher key. + * Session-less mode. + * Out-of place processing + * Scatter-gather support for chained mbufs (only out-of place and destination + mbuf must be contiguous) + +* **Added crypto performance test application.** + + Added a new performance test application for measuring performance + parameters of PMDs available in the crypto tree. + +* **Added Elastic Flow Distributor library (rte_efd).** + + Added a new library which uses perfect hashing to determine a target/value + for a given incoming flow key. + + The library does not store the key itself for lookup operations, and + therefore, lookup performance is not dependent on the key size. Also, the + target/value can be any arbitrary value (8 bits by default). Finally, the + storage requirement is much smaller than a hash-based flow table and + therefore, it can better fit in CPU cache and scale to millions of flow + keys. + + See the :ref:`Elastic Flow Distributor Library ` documentation in + the Programmers Guide document, for more information. + + +Resolved Issues +--------------- + +..

+ +.. This section should contain new features added in this release. Sample + format: + + * **Add a title in the past tense with a full stop.** + + Add a short 1-2 sentence description in the past tense. The description + should be enough to allow someone scanning the release notes to + understand the new feature. + + If the feature adds a lot of sub-features you can use a bullet list like + this: + + * Added feature foo to do something. + * Enhanced feature bar to do something else. + + Refer to the previous release notes for examples. + + This section is a comment. do not overwrite or remove it. + Also, make sure to start the actual text at the margin. + ========================================================= + +* **Reorganized mbuf structure.** + + The mbuf structure has been reorganized as follows: + + * Align fields to facilitate the writing of ``data_off``, ``refcnt``, and + ``nb_segs`` in one operation. + * Use 2 bytes for port and number of segments. + * Move the sequence number to the second cache line. + * Add a timestamp field. + * Set default value for ``refcnt``, ``next`` and ``nb_segs`` at mbuf free. + +* **Added mbuf raw free API.** + + Moved ``rte_mbuf_raw_free()`` and ``rte_pktmbuf_prefree_seg()`` functions to + the public API. + +* **Added free Tx mbuf on demand API.** + + Added a new function ``rte_eth_tx_done_cleanup()`` which allows an + application to request the driver to release mbufs that are no longer in use + from a Tx ring, independent of whether or not the ``tx_rs_thresh`` has been + crossed. + +* **Added device removal interrupt.** + + Added a new ethdev event ``RTE_ETH_DEV_INTR_RMV`` to signify + the sudden removal of a device. + This event can be advertised by PCI drivers and enabled accordingly. + +* **Added EAL dynamic log framework.** + + Added new APIs to dynamically register named log types, and control + the level of each type independently. + +* **Added descriptor status ethdev API.** + + Added a new API to get the status of a descriptor. + + For Rx, it is almost similar to the ``rx_descriptor_done`` API, except + it differentiates descriptors which are held by the driver and not + returned to the hardware. For Tx, it is a new API. + +* **Increased number of next hops for LPM IPv6 to 2^21.** + + The next_hop field has been extended from 8 bits to 21 bits for IPv6. + +* **Added VFIO hotplug support.** + + Added hotplug support for VFIO in addition to the existing UIO support. + +* **Added PowerPC support to pci probing for vfio-pci devices.** + + Enabled sPAPR IOMMU based pci probing for vfio-pci devices. + +* **Kept consistent PMD batching behavior.** + + Removed the limit of fm10k/i40e/ixgbe Tx burst size and vhost Rx/Tx burst size + in order to support the same policy of "make an best effort to Rx/Tx pkts" + for PMDs. + +* **Updated the ixgbe base driver.** + + Updated the ixgbe base driver, including the following changes: + + * Add link block check for KR. + * Complete HW initialization even if SFP is not present. + * Add VF xcast promiscuous mode. + +* **Added PowerPC support for i40e and its vector PMD.** + + Enabled i40e PMD and its vector PMD by default in PowerPC. + +* **Added VF max bandwidth setting in i40e.** + + Enabled capability to set the max bandwidth for a VF in i40e. + +* **Added VF TC min and max bandwidth setting in i40e.** + + Enabled capability to set the min and max allocated bandwidth for a TC on a + VF in i40. + +* **Added TC strict priority mode setting on i40e.** + + There are 2 Tx scheduling modes supported for TCs by i40e HW: round robin + mode and strict priority mode. By default the round robin mode is used. It + is now possible to change the Tx scheduling mode for a TC. This is a global + setting on a physical port. + +* **Added i40e dynamic device personalization support.** + + * Added dynamic device personalization processing to i40e firmware. + +* **Updated i40e driver to support MPLSoUDP/MPLSoGRE.** + + Updated i40e PMD to support MPLSoUDP/MPLSoGRE with MPLSoUDP/MPLSoGRE + supporting profiles which can be programmed by dynamic device personalization + (DDP) process. + +* **Added Cloud Filter for QinQ steering to i40e.** + + * Added a QinQ cloud filter on the i40e PMD, for steering traffic to a VM + using both VLAN tags. Note, this feature is not supported in Vector Mode. + +* **Updated mlx5 PMD.** + + Updated the mlx5 driver, including the following changes: + + * Added Generic flow API support for classification according to ether type. + * Extended Generic flow API support for classification of IPv6 flow + according to Vtc flow, Protocol and Hop limit. + * Added Generic flow API support for FLAG action. + * Added Generic flow API support for RSS action. + * Added support for TSO for non-tunneled and VXLAN packets. + * Added support for hardware Tx checksum offloads for VXLAN packets. + * Added support for user space Rx interrupt mode. + * Improved ConnectX-5 single core and maximum performance. + +* **Updated mlx4 PMD.** + + Updated the mlx4 driver, including the following changes: + + * Added support for Generic flow API basic flow items and actions. + * Added support for device removal event. + +* **Updated the sfc_efx driver.** + + * Added Generic Flow API support for Ethernet, VLAN, IPv4, IPv6, UDP and TCP + pattern items with QUEUE action for ingress traffic. + + * Added support for virtual functions (VFs). + +* **Added LiquidIO network PMD.** + + Added poll mode driver support for Cavium LiquidIO II server adapter VFs. + +* **Added Atomic Rules Arkville PMD.** + + Added a new poll mode driver for the Arkville family of + devices from Atomic Rules. The net/ark PMD supports line-rate + agnostic, multi-queue data movement on Arkville core FPGA instances. + +* **Added support for NXP DPAA2 - FSLMC bus.** + + Added the new bus "fslmc" driver for NXP DPAA2 devices. See the + "Network Interface Controller Drivers" document for more details of this new + driver. + +* **Added support for NXP DPAA2 Network PMD.** + + Added the new "dpaa2" net driver for NXP DPAA2 devices. See the + "Network Interface Controller Drivers" document for more details of this new + driver. + +* **Added support for the Wind River Systems AVP PMD.** + + Added a new networking driver for the AVP device type. Theses devices are + specific to the Wind River Systems virtualization platforms. + +* **Added vmxnet3 version 3 support.** + + Added support for vmxnet3 version 3 which includes several + performance enhancements such as configurable Tx data ring, Receive + Data Ring, and the ability to register memory regions. + +* **Updated the TAP driver.** + + Updated the TAP PMD to: + + * Support MTU modification. + * Support packet type for Rx. + * Support segmented packets on Rx and Tx. + * Speed up Rx on TAP when no packets are available. + * Support capturing traffic from another netdevice. + * Dynamically change link status when the underlying interface state changes. + * Added Generic Flow API support for Ethernet, VLAN, IPv4, IPv6, UDP and + TCP pattern items with DROP, QUEUE and PASSTHRU actions for ingress + traffic. + +* **Added MTU feature support to Virtio and Vhost.** + + Implemented new Virtio MTU feature in Vhost and Virtio: + + * Add ``rte_vhost_mtu_get()`` API to Vhost library. + * Enable Vhost PMD's MTU get feature. + * Get max MTU value from host in Virtio PMD + +* **Added interrupt mode support for virtio-user.** + + Implemented Rxq interrupt mode and LSC support for virtio-user as a virtual + device. Supported cases: + + * Rxq interrupt for virtio-user + vhost-user as the backend. + * Rxq interrupt for virtio-user + vhost-kernel as the backend. + * LSC interrupt for virtio-user + vhost-user as the backend. + +* **Added event driven programming model library (rte_eventdev).** + + This API introduces an event driven programming model. + + In a polling model, lcores poll ethdev ports and associated + Rx queues directly to look for a packet. By contrast in an event + driven model, lcores call the scheduler that selects packets for + them based on programmer-specified criteria. The Eventdev library + adds support for an event driven programming model, which offers + applications automatic multicore scaling, dynamic load balancing, + pipelining, packet ingress order maintenance and + synchronization services to simplify application packet processing. + + By introducing an event driven programming model, DPDK can support + both polling and event driven programming models for packet processing, + and applications are free to choose whatever model + (or combination of the two) best suits their needs. + +* **Added Software Eventdev PMD.** + + Added support for the software eventdev PMD. The software eventdev is a + software based scheduler device that implements the eventdev API. This + PMD allows an application to configure a pipeline using the eventdev + library, and run the scheduling workload on a CPU core. + +* **Added Cavium OCTEONTX Eventdev PMD.** + + Added the new octeontx ssovf eventdev driver for OCTEONTX devices. See the + "Event Device Drivers" document for more details on this new driver. + +* **Added information metrics library.** + + Added a library that allows information metrics to be added and updated + by producers, typically other libraries, for later retrieval by + consumers such as applications. It is intended to provide a + reporting mechanism that is independent of other libraries such + as ethdev. + +* **Added bit-rate calculation library.** + + Added a library that can be used to calculate device bit-rates. Calculated + bitrates are reported using the metrics library. + +* **Added latency stats library.** + + Added a library that measures packet latency. The collected statistics are + jitter and latency. For latency the minimum, average, and maximum is + measured. + +* **Added NXP DPAA2 SEC crypto PMD.** + + A new "dpaa2_sec" hardware based crypto PMD for NXP DPAA2 devices has been + added. See the "Crypto Device Drivers" document for more details on this + driver. + +* **Updated the Cryptodev Scheduler PMD.** + + * Added a packet-size based distribution mode, which distributes the enqueued + crypto operations among two slaves, based on their data lengths. + * Added fail-over scheduling mode, which enqueues crypto operations to a + primary slave first. Then, any operation that cannot be enqueued is + enqueued to a secondary slave. + * Added mode specific option support, so each scheduling mode can + now be configured individually by the new API. + +* **Updated the QAT PMD.** + + The QAT PMD has been updated with additional support for: + + * AES DOCSIS BPI algorithm. + * DES DOCSIS BPI algorithm. + * ZUC EEA3/EIA3 algorithms. + +* **Updated the AESNI MB PMD.** + + The AESNI MB PMD has been updated with additional support for: + + * AES DOCSIS BPI algorithm. + +* **Updated the OpenSSL PMD.** + + The OpenSSL PMD has been updated with additional support for: + + * DES DOCSIS BPI algorithm. + + +Resolved Issues +--------------- + +.. This section should contain bug fixes added to the relevant + sections. Sample format: + + * **code/section Fixed issue in the past tense with a full stop.** + + Add a short 1-2 sentence description of the resolved issue in the past + tense. + + The title should contain the code/lib section like a commit message. + + Add the entries in alphabetic order in the relevant sections below. + + This section is a comment. do not overwrite or remove it. + Also, make sure to start the actual text at the margin. + ========================================================= + + +* **l2fwd-keepalive: Fixed unclean shutdowns.** + + Added clean shutdown to l2fwd-keepalive so that it can free up + stale resources used for inter-process communication. + + +Known Issues +------------ + +.. This section should contain new known issues in this release. Sample format: + + * **Add title in present tense with full stop.** + + Add a short 1-2 sentence description of the known issue in the present + tense. Add information on any known workarounds. + + This section is a comment. do not overwrite or remove it. + Also, make sure to start the actual text at the margin. + ========================================================= + +* **LSC interrupt doesn't work for virtio-user + vhost-kernel.** + + LSC interrupt cannot be detected when setting the backend, tap device, + up/down as we fail to find a way to monitor such event. + + +API Changes +----------- + +.. This section should contain API changes. Sample format: + + * Add a short 1-2 sentence description of the API change. Use fixed width + quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past + tense. + + This section is a comment. do not overwrite or remove it. + Also, make sure to start the actual text at the margin. + ========================================================= + +* The LPM ``next_hop`` field is extended from 8 bits to 21 bits for IPv6 + while keeping ABI compatibility. + +* **Reworked rte_ring library.** + + The rte_ring library has been reworked and updated. The following changes + have been made to it: + + * Removed the build-time setting ``CONFIG_RTE_RING_SPLIT_PROD_CONS``. + * Removed the build-time setting ``CONFIG_RTE_LIBRTE_RING_DEBUG``. + * Removed the build-time setting ``CONFIG_RTE_RING_PAUSE_REP_COUNT``. + * Removed the function ``rte_ring_set_water_mark`` as part of a general + removal of watermarks support in the library. + * Added an extra parameter to the burst/bulk enqueue functions to + return the number of free spaces in the ring after enqueue. This can + be used by an application to implement its own watermark functionality. + * Added an extra parameter to the burst/bulk dequeue functions to return + the number elements remaining in the ring after dequeue. + * Changed the return value of the enqueue and dequeue bulk functions to + match that of the burst equivalents. In all cases, ring functions which + operate on multiple packets now return the number of elements enqueued + or dequeued, as appropriate. The updated functions are: + + - ``rte_ring_mp_enqueue_bulk`` + - ``rte_ring_sp_enqueue_bulk`` + - ``rte_ring_enqueue_bulk`` + - ``rte_ring_mc_dequeue_bulk`` + - ``rte_ring_sc_dequeue_bulk`` + - ``rte_ring_dequeue_bulk`` + + NOTE: the above functions all have different parameters as well as + different return values, due to the other listed changes above. This + means that all instances of the functions in existing code will be + flagged by the compiler. The return value usage should be checked + while fixing the compiler error due to the extra parameter. + +* **Reworked rte_vhost library.** + + The rte_vhost library has been reworked to make it generic enough so that + the user could build other vhost-user drivers on top of it. To achieve this + the following changes have been made: + + * The following vhost-pmd APIs are removed: + + * ``rte_eth_vhost_feature_disable`` + * ``rte_eth_vhost_feature_enable`` + * ``rte_eth_vhost_feature_get`` + + * The vhost API ``rte_vhost_driver_callback_register(ops)`` is reworked to + be per vhost-user socket file. Thus, it takes one more argument: + ``rte_vhost_driver_callback_register(path, ops)``. + + * The vhost API ``rte_vhost_get_queue_num`` is deprecated, instead, + ``rte_vhost_get_vring_num`` should be used. + + * The following macros are removed in ``rte_virtio_net.h`` + + * ``VIRTIO_RXQ`` + * ``VIRTIO_TXQ`` + * ``VIRTIO_QNUM`` + + * The following net specific header files are removed in ``rte_virtio_net.h`` + + * ``linux/virtio_net.h`` + * ``sys/socket.h`` + * ``linux/if.h`` + * ``rte_ether.h`` + + * The vhost struct ``virtio_net_device_ops`` is renamed to + ``vhost_device_ops`` + + * The vhost API ``rte_vhost_driver_session_start`` is removed. Instead, + ``rte_vhost_driver_start`` should be used, and there is no need to create + a thread to call it. + + * The vhost public header file ``rte_virtio_net.h`` is renamed to + ``rte_vhost.h`` + + +ABI Changes +----------- + +.. This section should contain ABI changes. Sample format: + + * Add a short 1-2 sentence description of the ABI change that was announced + in the previous releases and made in this release. Use fixed width quotes + for ``rte_function_names`` or ``rte_struct_names``. Use the past tense. + + This section is a comment. do not overwrite or remove it. + Also, make sure to start the actual text at the margin. + ========================================================= + +* **Reorganized the mbuf structure.** + + The order and size of the fields in the ``mbuf`` structure changed, + as described in the `New Features`_ section. + +* The ``rte_cryptodev_info.sym`` structure has a new field ``max_nb_sessions_per_qp`` + to support drivers which may support a limited number of sessions per queue_pair. + + +Removed Items +------------- + +.. This section should contain removed items in this release. Sample format: + + * Add a short 1-2 sentence description of the removed item in the past + tense. + + This section is a comment. do not overwrite or remove it. + Also, make sure to start the actual text at the margin. + ========================================================= + +* KNI vhost support has been removed. + +* The dpdk_qat sample application has been removed. + +Shared Library Versions +----------------------- + +..

+ +New Features +------------ + +.. This section should contain new features added in this release. Sample + format: + + * **Add a title in the past tense with a full stop.** + + Add a short 1-2 sentence description in the past tense. The description + should be enough to allow someone scanning the release notes to + understand the new feature. + + If the feature adds a lot of sub-features you can use a bullet list like + this: + + * Added feature foo to do something. + * Enhanced feature bar to do something else. + + Refer to the previous release notes for examples. + + This section is a comment. do not overwrite or remove it. + Also, make sure to start the actual text at the margin. + ========================================================= + +* **Extended port_id range from uint8_t to uint16_t.** + + Increased the ``port_id`` range from 8 bits to 16 bits in order to support + more than 256 ports in DPDK. All ethdev APIs which have ``port_id`` as + parameter have been changed. + +* **Modified the return type of rte_eth_stats_reset.** + + Changed return type of ``rte_eth_stats_reset`` from ``void`` to ``int`` so + that the caller can determine whether a device supports the operation or not + and if the operation was carried out. + +* **Added a new driver for Marvell Armada 7k/8k devices.** + + Added the new ``mrvl`` net driver for Marvell Armada 7k/8k devices. See the + :doc:`../nics/mrvl` NIC guide for more details on this new driver. + +* **Updated mlx4 driver.** + + Updated the mlx4 driver including the following changes: + + * Isolated mode (rte_flow) can now be enabled anytime, not only during + initial device configuration. + * Flow rules now support up to 4096 priority levels usable at will by + applications. + * Enhanced error message to help debugging invalid/unsupported flow rules. + * Flow rules matching all multicast and promiscuous traffic are now allowed. + * No more software restrictions on flow rules with the RSS action, their + configuration is much more flexible. + * Significantly reduced memory footprint for Rx and Tx queue objects. + * While supported, UDP RSS is temporarily disabled due to a remaining issue + with its support in the Linux kernel. + * The new RSS implementation does not automatically spread traffic according + to the inner packet of VXLAN frames anymore, only the outer one (like + other PMDs). + * Partial (Tx only) support for secondary processes was broken and had to be + removed. + * Refactored driver to get rid of dependency on the components provided by + Mellanox OFED and instead rely on the current and public rdma-core + package and Linux version from now on. + * Removed compile-time limitation on number of device instances the PMD + can support. + +* **Updated mlx5 driver.** + + Updated the mlx5 driver including the following changes: + + * Enabled the PMD to run on top of upstream Linux kernel and rdma-core + libs, removing the dependency on specific Mellanox OFED libraries. + * Improved PMD latency performance. + * Improved PMD memory footprint. + * Added support for vectorized Rx/Tx burst for ARMv8. + * Added support for secondary process. + * Added support for flow counters. + * Added support for Rx hardware timestamp offload. + * Added support for device removal event. + +* **Added SoftNIC PMD.** + + Added a new SoftNIC PMD. This virtual device provides applications with + software fallback support for traffic management. + +* **Added support for NXP DPAA Devices.** + + Added support for NXP's DPAA devices - LS104x series. This includes: + + * DPAA Bus driver + * DPAA Mempool driver for supporting offloaded packet memory pool + * DPAA PMD for DPAA devices + + See the :doc:`../nics/dpaa` document for more details of this new driver. + +* **Updated support for Cavium OCTEONTX Device.** + + Updated support for Cavium's OCTEONTX device (CN83xx). This includes: + + * OCTEONTX Mempool driver for supporting offloaded packet memory pool + * OCTEONTX Ethdev PMD + * OCTEONTX Eventdev-Ethdev Rx adapter + + See the :doc:`../nics/octeontx` document for more details of this new driver. + +* **Added PF support to the Netronome NFP PMD.** + + Added PF support to the Netronome NFP PMD. Previously the NFP PMD only + supported VFs. PF support is just as a basic DPDK port and has no VF + management yet. + + PF support comes with firmware upload support which allows the PMD to + independently work from kernel netdev NFP drivers. + + NFP 4000 devices are also now supported along with previous 6000 devices. + +* **Updated bnxt PMD.** + + Major enhancements include: + + * Support for Flow API + * Support for Tx and Rx descriptor status functions + +* **Added bus agnostic functions to cryptodev for PMD initialization** + + Added new PMD assist, bus independent, functions + ``rte_cryptodev_pmd_parse_input_args()``, ``rte_cryptodev_pmd_create()`` and + ``rte_cryptodev_pmd_destroy()`` for drivers to manage creation and + destruction of new device instances. + +* **Updated QAT crypto PMD.** + + Added several performance enhancements: + + * Removed atomics from the internal queue pair structure. + * Added coalesce writes to HEAD CSR on response processing. + * Added coalesce writes to TAIL CSR on request processing. + + In addition support was added for the AES CCM algorithm. + +* **Updated the AESNI MB PMD.** + + The AESNI MB PMD has been updated with additional support for: + + * The DES CBC algorithm. + * The DES DOCSIS BPI algorithm. + + This change requires version 0.47 of the IPSec Multi-buffer library. For + more details see the :doc:`../cryptodevs/aesni_mb` documentation. + +* **Updated the OpenSSL PMD.** + + The OpenSSL PMD has been updated with additional support for: + + * The DES CBC algorithm. + * The AES CCM algorithm. + +* **Added NXP DPAA SEC crypto PMD.** + + A new ``dpaa_sec`` hardware based crypto PMD for NXP DPAA devices has been + added. See the :doc:`../cryptodevs/dpaa_sec` document for more details. + +* **Added MRVL crypto PMD.** + + A new crypto PMD has been added, which provides several ciphering and hashing + algorithms. All cryptography operations use the MUSDK library crypto API. + See the :doc:`../cryptodevs/mrvl` document for more details. + +* **Add new benchmarking mode to dpdk-test-crypto-perf application.** + + Added a new "PMD cyclecount" benchmark mode to the ``dpdk-test-crypto-perf`` + application to display a detailed breakdown of CPU cycles used by hardware + acceleration. + +* **Added the Security Offload Library.** + + Added an experimental library - ``rte_security``. This provide security APIs + for protocols like IPSec using inline ipsec offload to ethernet devices or + full protocol offload with lookaside crypto devices. + + See the :doc:`../prog_guide/rte_security` section of the DPDK Programmers + Guide document for more information. + +* **Updated the DPAA2_SEC crypto driver to support rte_security.** + + Updated the ``dpaa2_sec`` crypto PMD to support ``rte_security`` lookaside + protocol offload for IPSec. + +* **Updated the IXGBE ethernet driver to support rte_security.** + + Updated ixgbe ethernet PMD to support ``rte_security`` inline IPSec offload. + +* **Updated i40e driver to support GTP-C/GTP-U.** + + Updated i40e PMD to support GTP-C/GTP-U with GTP-C/GTP-U supporting + profiles which can be programmed by dynamic device personalization (DDP) + process. + +* **Added the i40e ethernet driver to support queue region feature.** + + This feature enable queue regions configuration for RSS in PF, + so that different traffic classes or different packet + classification types can be separated into different queues in + different queue regions. + +* **Updated ipsec-secgw application to support rte_security.** + + Updated the ``ipsec-secgw`` sample application to support ``rte_security`` + actions for ipsec inline and full protocol offload using lookaside crypto + offload. + +* **Added IOMMU support to libvhost-user** + + Implemented device IOTLB in the Vhost-user backend, and enabled Virtio's + IOMMU feature. The feature is disabled by default, and can be enabled by + setting ``RTE_VHOST_USER_IOMMU_SUPPORT`` flag at vhost device registration + time. + +* **Added the Event Ethernet Adapter Library.** + + Added the Event Ethernet Adapter library. This library provides APIs for + eventdev applications to configure the ethdev for eventdev packet flow. + +* **Updated DPAA2 Event PMD for the Event Ethernet Adapter.** + + Added support for the eventdev ethernet adapter for DPAA2. + +* **Added Membership library (rte_member).** + + Added a new data structure library called the Membership Library. + + The Membership Library is an extension and generalization of a traditional + filter (for example Bloom Filter) structure that has multiple usages in a + wide variety of workloads and applications. In general, the Membership + Library is a data structure that provides a "set-summary" and responds to + set-membership queries whether a certain member belongs to a set(s). + + The library provides APIs for DPDK applications to insert a new member, + delete an existing member, and query the existence of a member in a given + set, or a group of sets. For the case of a group of sets the library will + return not only whether the element has been inserted in one of the sets but + also which set it belongs to. + + See the :doc:`../prog_guide/member_lib` documentation in the Programmers + Guide, for more information. + +* **Added the Generic Segmentation Offload Library.** + + Added the Generic Segmentation Offload (GSO) library to enable + applications to split large packets (e.g. MTU is 64KB) into small + ones (e.g. MTU is 1500B). Supported packet types are: + + * TCP/IPv4 packets. + * VxLAN packets, which must have an outer IPv4 header, and contain + an inner TCP/IPv4 packet. + * GRE packets, which must contain an outer IPv4 header, and inner + TCP/IPv4 headers. + + The GSO library doesn't check if the input packets have correct + checksums, and doesn't update checksums for output packets. + Additionally, the GSO library doesn't process IP fragmented packets. + +* **Added the Flow Classification Library.** + + Added an experimental Flow Classification library to provide APIs for DPDK + applications to classify an input packet by matching it against a set of + flow rules. It uses the ``librte_table`` API to manage the flow rules. + + +Resolved Issues +--------------- + +.. This section should contain bug fixes added to the relevant + sections. Sample format: + + * **code/section Fixed issue in the past tense with a full stop.** + + Add a short 1-2 sentence description of the resolved issue in the past + tense. + + The title should contain the code/lib section like a commit message. + + Add the entries in alphabetic order in the relevant sections below. + + This section is a comment. do not overwrite or remove it. + Also, make sure to start the actual text at the margin. + ========================================================= + + +* **Service core fails to call service callback due to atomic lock** + + In a specific configuration of multi-thread unsafe services and service + cores, a service core previously did not correctly release the atomic lock + on the service. This would result in the cores polling the service, but it + looked like another thread was executing the service callback. The logic for + atomic locking of the services has been fixed and refactored for readability. + + +API Changes +----------- + +.. This section should contain API changes. Sample format: + + * Add a short 1-2 sentence description of the API change. Use fixed width + quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past + tense. + + This section is a comment. do not overwrite or remove it. + Also, make sure to start the actual text at the margin. + ========================================================= + +* **Ethdev device name length increased.** + + The size of internal device name has been increased to 64 characters + to allow for storing longer bus specific names. + +* **Removed the Ethdev RTE_ETH_DEV_DETACHABLE flag.** + + Removed the Ethdev ``RTE_ETH_DEV_DETACHABLE`` flag. This flag is not + required anymore, with the new hotplug implementation. It has been removed + from the ether library. Its semantics are now expressed at the bus and PMD + level. + +* **Service cores API updated for usability** + + The service cores API has been changed, removing pointers from the API where + possible, and instead using integer IDs to identify each service. This + simplifies application code, aids debugging, and provides better + encapsulation. A summary of the main changes made is as follows: + + * Services identified by ID not by ``rte_service_spec`` pointer + * Reduced API surface by using ``set`` functions instead of enable/disable + * Reworked ``rte_service_register`` to provide the service ID to registrar + * Reworked start and stop APIs into ``rte_service_runstate_set`` + * Added API to set runstate of service implementation to indicate readiness + +* **The following changes have been made in the mempool library** + + * Moved ``flags`` datatype from ``int`` to ``unsigned int`` for + ``rte_mempool``. + * Removed ``__rte_unused int flag`` param from ``rte_mempool_generic_put`` + and ``rte_mempool_generic_get`` API. + * Added ``flags`` param in ``rte_mempool_xmem_size`` and + ``rte_mempool_xmem_usage``. + * ``rte_mem_phy2mch`` was used in Xen dom0 to obtain the physical address; + remove this API as Xen dom0 support was removed. + +* **Added IOVA aliases related to physical address handling.** + + Some data types, structure members and functions related to physical address + handling are deprecated and have new aliases with IOVA wording. For example: + + * ``phys_addr_t`` can be often replaced by ``rte_iova_t`` of same size. + * ``RTE_BAD_PHYS_ADDR`` is often replaced by ``RTE_BAD_IOVA`` of same value. + * ``rte_memseg.phys_addr`` is aliased with ``rte_memseg.iova_addr``. + * ``rte_mem_virt2phy()`` can often be replaced by ``rte_mem_virt2iova``. + * ``rte_malloc_virt2phy`` is aliased with ``rte_malloc_virt2iova``. + * ``rte_memzone.phys_addr`` is aliased with ``rte_memzone.iova``. + * ``rte_mempool_objhdr.physaddr`` is aliased with + ``rte_mempool_objhdr.iova``. + * ``rte_mempool_memhdr.phys_addr`` is aliased with + ``rte_mempool_memhdr.iova``. + * ``rte_mempool_virt2phy()`` can be replaced by ``rte_mempool_virt2iova()``. + * ``rte_mempool_populate_phys*()`` are aliased with + ``rte_mempool_populate_iova*()`` + * ``rte_mbuf.buf_physaddr`` is aliased with ``rte_mbuf.buf_iova``. + * ``rte_mbuf_data_dma_addr*()`` are aliased with ``rte_mbuf_data_iova*()``. + * ``rte_pktmbuf_mtophys*`` are aliased with ``rte_pktmbuf_iova*()``. + +* **PCI bus API moved outside of the EAL** + + The PCI bus previously implemented within the EAL has been moved. + A first part has been added as an RTE library providing PCI helpers to + parse device locations or other such utilities. + A second part consisting of the actual bus driver has been moved to its + proper subdirectory, without changing its functionalities. + + As such, several PCI-related functions are not exposed by the EAL anymore: + + * ``rte_pci_detach`` + * ``rte_pci_dump`` + * ``rte_pci_ioport_map`` + * ``rte_pci_ioport_read`` + * ``rte_pci_ioport_unmap`` + * ``rte_pci_ioport_write`` + * ``rte_pci_map_device`` + * ``rte_pci_probe`` + * ``rte_pci_probe_one`` + * ``rte_pci_read_config`` + * ``rte_pci_register`` + * ``rte_pci_scan`` + * ``rte_pci_unmap_device`` + * ``rte_pci_unregister`` + * ``rte_pci_write_config`` + + These functions are made available either as part of ``librte_pci`` or + ``librte_bus_pci``. + +* **Moved vdev bus APIs outside of the EAL** + + Moved the following APIs from ``librte_eal`` to ``librte_bus_vdev``: + + * ``rte_vdev_init`` + * ``rte_vdev_register`` + * ``rte_vdev_uninit`` + * ``rte_vdev_unregister`` + +* **Add return value to stats_get dev op API** + + The ``stats_get`` dev op API return value has been changed to be int. + In this way PMDs can return an error value in case of failure at stats + getting process time. + +* **Modified the rte_cryptodev_allocate_driver function.** + + Modified the ``rte_cryptodev_allocate_driver()`` function in the cryptodev + library. An extra parameter ``struct cryptodev_driver *crypto_drv`` has been + added. + +* **Removed virtual device bus specific functions from librte_cryptodev.** + + The functions ``rte_cryptodev_vdev_parse_init_params()`` and + ``rte_cryptodev_vdev_pmd_init()`` have been removed from librte_cryptodev + and have been replaced by non bus specific functions + ``rte_cryptodev_pmd_parse_input_args()`` and ``rte_cryptodev_pmd_create()``. + + The ``rte_cryptodev_create_vdev()`` function was removed to avoid the + dependency on vdev in librte_cryptodev; instead, users can call + ``rte_vdev_init()`` directly. + +* **Removed PCI device bus specific functions from librte_cryptodev.** + + The functions ``rte_cryptodev_pci_generic_probe()`` and + ``rte_cryptodev_pci_generic_remove()`` have been removed from librte_cryptodev + and have been replaced by non bus specific functions + ``rte_cryptodev_pmd_create()`` and ``rte_cryptodev_pmd_destroy()``. + +* **Removed deprecated functions to manage log level or type.** + + The functions ``rte_set_log_level()``, ``rte_get_log_level()``, + ``rte_set_log_type()`` and ``rte_get_log_type()`` have been removed. + + They are respectively replaced by ``rte_log_set_global_level()``, + ``rte_log_get_global_level()``, ``rte_log_set_level()`` and + ``rte_log_get_level()``. + +* **Removed mbuf flags PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT.** + + The ``mbuf`` flags ``PKT_RX_VLAN_PKT`` and ``PKT_RX_QINQ_PKT`` have + been removed since their behavior was not properly described. + +* **Added mbuf flags PKT_RX_VLAN and PKT_RX_QINQ.** + + Two ``mbuf`` flags have been added to indicate that the VLAN + identifier has been saved in in the ``mbuf`` structure. For instance: + + - If VLAN is not stripped and TCI is saved: ``PKT_RX_VLAN`` + - If VLAN is stripped and TCI is saved: ``PKT_RX_VLAN | PKT_RX_VLAN_STRIPPED`` + +* **Modified the vlan_offload_set_t function prototype in the ethdev library.** + + Modified the ``vlan_offload_set_t`` function prototype in the ethdev + library. The return value has been changed from ``void`` to ``int`` so the + caller can determine whether the backing device supports the operation or if + the operation was successfully performed. + + +ABI Changes +----------- + +.. This section should contain ABI changes. Sample format: + + * Add a short 1-2 sentence description of the ABI change that was announced + in the previous releases and made in this release.

Features +------------ + +.. This section should contain new features added in this release. Sample + format: + + * **Add a title in the past tense with a full stop.** + + Add a short 1-2 sentence description in the past tense. The description + should be enough to allow someone scanning the release notes to + understand the new feature. + + If the feature adds a lot of sub-features you can use a bullet list like + this: + + * Added feature foo to do something. + * Enhanced feature bar to do something else. + + Refer to the previous release notes for examples. + + This section is a comment. do not overwrite or remove it. + Also, make sure to start the actual text at the margin. + ========================================================= + +* **Added function to allow releasing internal EAL resources on exit.** + + During ``rte_eal_init()`` EAL allocates memory from hugepages to enable its + core libraries to perform their tasks. The ``rte_eal_cleanup()`` function + releases these resources, ensuring that no hugepage memory is leaked. It is + expected that all DPDK applications call ``rte_eal_cleanup()`` before + exiting. Not calling this function could result in leaking hugepages, leading + to failure during initialization of secondary processes. + +* **Added igb, ixgbe and i40e ethernet driver to support RSS with flow API.** + + Added support for igb, ixgbe and i40e NICs with existing RSS configuration + using the ``rte_flow`` API. + + Also enabled queue region configuration using the ``rte_flow`` API for i40e. + +* **Updated i40e driver to support PPPoE/PPPoL2TP.** + + Updated i40e PMD to support PPPoE/PPPoL2TP with PPPoE/PPPoL2TP supporting + profiles which can be programmed by dynamic device personalization (DDP) + process. + +* **Added MAC loopback support for i40e.** + + Added MAC loopback support for i40e in order to support test tasks requested + by users. It will setup ``Tx -> Rx`` loopback link according to the device + configuration. + +* **Added support of run time determination of number of queues per i40e VF.** + + The number of queue per VF is determined by its host PF. If the PCI address + of an i40e PF is ``aaaa:bb.cc``, the number of queues per VF can be + configured with EAL parameter like ``-w aaaa:bb.cc,queue-num-per-vf=n``. The + value n can be 1, 2, 4, 8 or 16. If no such parameter is configured, the + number of queues per VF is 4 by default. + +* **Updated mlx5 driver.** + + Updated the mlx5 driver including the following changes: + + * Enabled compilation as a plugin, thus removed the mandatory dependency with rdma-core. + With the special compilation, the rdma-core libraries will be loaded only in case + Mellanox device is being used. For binaries creation the PMD can be enabled, still not + requiring from every end user to install rdma-core. + * Improved multi-segment packet performance. + * Changed driver name to use the PCI address to be compatible with OVS-DPDK APIs. + * Extended statistics for physical port packet/byte counters. + * Converted to the new offloads API. + * Supported device removal check operation. + +* **Updated mlx4 driver.** + + Updated the mlx4 driver including the following changes: + + * Enabled compilation as a plugin, thus removed the mandatory dependency with rdma-core. + With the special compilation, the rdma-core libraries will be loaded only in case + Mellanox device is being used. For binaries creation the PMD can be enabled, still not + requiring from every end user to install rdma-core. + * Improved data path performance. + * Converted to the new offloads API. + * Supported device removal check operation. + +* **Added NVGRE and UDP tunnels support in Solarflare network PMD.** + + Added support for NVGRE, VXLAN and GENEVE tunnels. + + * Added support for UDP tunnel ports configuration. + * Added tunneled packets classification. + * Added inner checksum offload. + +* **Added AVF (Adaptive Virtual Function) net PMD.** + + Added a new net PMD called AVF (Adaptive Virtual Function), which supports + Intel® Ethernet Adaptive Virtual Function (AVF) with features such as: + + * Basic Rx/Tx burst + * SSE vectorized Rx/Tx burst + * Promiscuous mode + * MAC/VLAN offload + * Checksum offload + * TSO offload + * Jumbo frame and MTU setting + * RSS configuration + * stats + * Rx/Tx descriptor status + * Link status update/event + +* **Added feature supports for live migration from vhost-net to vhost-user.** + + Added feature supports for vhost-user to make live migration from vhost-net + to vhost-user possible. The features include: + + * ``VIRTIO_F_ANY_LAYOUT`` + * ``VIRTIO_F_EVENT_IDX`` + * ``VIRTIO_NET_F_GUEST_ECN``, ``VIRTIO_NET_F_HOST_ECN`` + * ``VIRTIO_NET_F_GUEST_UFO``, ``VIRTIO_NET_F_HOST_UFO`` + * ``VIRTIO_NET_F_GSO`` + + Also added ``VIRTIO_NET_F_GUEST_ANNOUNCE`` feature support in virtio pmd. + In a scenario where the vhost backend doesn't have the ability to generate + RARP packets, the VM running virtio pmd can still be live migrated if + ``VIRTIO_NET_F_GUEST_ANNOUNCE`` feature is negotiated. + +* **Updated the AESNI-MB PMD.** + + The AESNI-MB PMD has been updated with additional support for: + + * AES-CCM algorithm. + +* **Updated the DPAA_SEC crypto driver to support rte_security.** + + Updated the ``dpaa_sec`` crypto PMD to support ``rte_security`` lookaside + protocol offload for IPsec. + +* **Added Wireless Base Band Device (bbdev) abstraction.** + + The Wireless Baseband Device library is an acceleration abstraction + framework for 3gpp Layer 1 processing functions that provides a common + programming interface for seamless operation on integrated or discrete + hardware accelerators or using optimized software libraries for signal + processing. + + The current release only supports 3GPP CRC, Turbo Coding and Rate + Matching operations, as specified in 3GPP TS 36.212. + + See the :doc:`../prog_guide/bbdev` programmer's guide for more details. + +* **Added New eventdev Ordered Packet Distribution Library (OPDL) PMD.** + + The OPDL (Ordered Packet Distribution Library) eventdev is a specific + implementation of the eventdev API. It is particularly suited to packet + processing workloads that have high throughput and low latency requirements. + All packets follow the same path through the device. The order in which + packets follow is determined by the order in which queues are set up. + Events are left on the ring until they are transmitted. As a result packets + do not go out of order. + + With this change, applications can use the OPDL PMD via the eventdev api. + +* **Added new pipeline use case for dpdk-test-eventdev application.** + + Added a new "pipeline" use case for the ``dpdk-test-eventdev`` application. + The pipeline case can be used to simulate various stages in a real world + application from packet receive to transmit while maintaining the packet + ordering. It can also be used to measure the performance of the event device + across the stages of the pipeline. + + The pipeline use case has been made generic to work with all the event + devices based on the capabilities. + +* **Updated Eventdev sample application to support event devices based on capability.** + + Updated the Eventdev pipeline sample application to support various types of + pipelines based on the capabilities of the attached event and ethernet + devices. Also, renamed the application from software PMD specific + ``eventdev_pipeline_sw_pmd`` to the more generic ``eventdev_pipeline``. + +* **Added Rawdev, a generic device support library.** + + The Rawdev library provides support for integrating any generic device type with + the DPDK framework. Generic devices are those which do not have a pre-defined + type within DPDK, for example, ethernet, crypto, event etc. + + A set of northbound APIs have been defined which encompass a generic set of + operations by allowing applications to interact with device using opaque + structures/buffers. Also, southbound APIs provide a means of integrating devices + either as as part of a physical bus (PCI, FSLMC etc) or through ``vdev``. + + See the :doc:`../prog_guide/rawdev` programmer's guide for more details. + +* **Added new multi-process communication channel.** + + Added a generic channel in EAL for multi-process (primary/secondary) communication. + Consumers of this channel need to register an action with an action name to response + a message received; the actions will be identified by the action name and executed + in the context of a new dedicated thread for this channel. The list of new APIs: + + * ``rte_mp_register`` and ``rte_mp_unregister`` are for action (un)registration. + * ``rte_mp_sendmsg`` is for sending a message without blocking for a response. + * ``rte_mp_request`` is for sending a request message and will block until + it gets a reply message which is sent from the peer by ``rte_mp_reply``. + +* **Added GRO support for VxLAN-tunneled packets.** + + Added GRO support for VxLAN-tunneled packets. Supported VxLAN packets + must contain an outer IPv4 header and inner TCP/IPv4 headers. VxLAN + GRO doesn't check if input packets have correct checksums and doesn't + update checksums for output packets. Additionally, it assumes the + packets are complete (i.e., ``MF==0 && frag_off==0``), when IP + fragmentation is possible (i.e., ``DF==0``). + +* **Increased default Rx and Tx ring size in sample applications.** + + Increased the default ``RX_RING_SIZE`` and ``TX_RING_SIZE`` to 1024 entries + in testpmd and the sample applications to give better performance in the + general case. The user should experiment with various Rx and Tx ring sizes + for their specific application to get best performance. + +* **Added new DPDK build system using the tools "meson" and "ninja" [EXPERIMENTAL].** + + Added support for building DPDK using ``meson`` and ``ninja``, which gives + additional features, such as automatic build-time configuration, over the + current build system using ``make``. For instructions on how to do a DPDK build + using the new system, see the instructions in ``doc/build-sdk-meson.txt``. + + .. note:: + + This new build system support is incomplete at this point and is added + as experimental in this release. The existing build system using ``make`` + is unaffected by these changes, and can continue to be used for this + and subsequent releases until such time as it's deprecation is announced. + + +Shared Library Versions +----------------------- + +..

The 16 bit packet_type in the mbuf structure was changed to 32 bits + and used for this purpose. + + To avoid breaking ABI compatibility, the code changes for this feature are + enclosed in a ``RTE_NEXT_ABI`` ifdef. This is enabled by default but can be + turned off for ABI compatibility with DPDK R2.0. + + +* **Reworked memzone to be allocated by malloc and also support freeing.** + + In the memory hierarchy, memsegs are groups of physically contiguous + hugepages, memzones are slices of memsegs, and malloc slices memzones + into smaller memory chunks. + + This feature modifies ``malloc()`` so it partitions memsegs instead of + memzones. Now memzones allocate their memory from the malloc heap. + + Backward compatibility with API and ABI are maintained. + + This allow memzones, and any other structure based on memzones, for example + mempools, to be freed. Currently only the API from freeing memzones is + supported. + + +* **Interrupt mode PMD.** + + This feature introduces a low-latency one-shot RX interrupt into DPDK. It + also adds a polling and interrupt mode switch control example. + + DPDK userspace interrupt notification and handling mechanism is based on + UIO/VFIO with the following limitations: + + * Per queue RX interrupt events are only allowed in VFIO which supports + multiple MSI-X vectors. + * In UIO, the RX interrupt shares the same vector with other + interrupts. When the RX interrupt and LSC interrupt are both enabled, only + the former is available. + * RX interrupt is only implemented for the linuxapp target. + * The feature is only currently enabled for tow PMDs: ixgbe and igb. + + +* **Packet Framework enhancements.** + + Several enhancements were made to the Packet Framework: + + * A new configuration file syntax has been introduced for IP pipeline + applications. Parsing of the configuration file is changed. + * Implementation of the IP pipeline application is modified to make it more + structured and user friendly. + * Implementation of the command line interface (CLI) for each pipeline type + has been moved to the separate compilation unit. Syntax of pipeline CLI + commands has been changed. + * Initialization of IP pipeline is modified to match the new parameters + structure. + * New implementation of pass-through pipeline, firewall pipeline, routing + pipeline, and flow classification has been added. + * Master pipeline with CLI interface has been added. + * Added extended documentation of the IP Pipeline. + + +* **Added API for IEEE1588 timestamping.** + + This feature adds an ethdev API to enable, disable and read IEEE1588/802.1AS + PTP timestamps from devices that support it. The following functions were + added: + + * ``rte_eth_timesync_enable()`` + * ``rte_eth_timesync_disable()`` + * ``rte_eth_timesync_read_rx_timestamp()`` + * ``rte_eth_timesync_read_tx_timestamp()`` + + The "ieee1588" forwarding mode in testpmd was also refactored to demonstrate + the new API. + + +* **Added multicast address filtering.** + + Added multicast address filtering via a new ethdev function + ``set_mc_addr_list()``. + + This overcomes a limitation in previous releases where the receipt of + multicast packets on a given port could only be enabled by invoking the + ``rte_eth_allmulticast_enable()`` function. This method did not work for VFs + in SR-IOV architectures when the host PF driver does not allow these + operation on VFs. In such cases, joined multicast addresses had to be added + individually to the set of multicast addresses that are filtered by the [VF] + port. + + +* **Added Flow Director extensions.** + + Several Flow Director extensions were added such as: + + * Support for RSS and Flow Director hashes in vector RX. + * Added Flow Director for L2 payload. + + +* **Added RSS hash key size query per port.** + + This feature supports querying the RSS hash key size of each port. A new + field ``hash_key_size`` has been added in the ``rte_eth_dev_info`` struct + for storing hash key size in bytes. + + +* **Added userspace ethtool support.** + + Added userspace ethtool support to provide a familiar interface for + applications that manage devices via kernel-space ``ethtool_op`` and + ``net_device_op``. + + The initial implementation focuses on operations that can be implemented + through existing ``netdev`` APIs. More operations will be supported in later + releases. + + +* **Updated the ixgbe base driver.** + + The ixgbe base driver was updated with several changes including the + following: + + * Added a new 82599 device id. + * Added new X550 PHY ids. + * Added SFP+ dual-speed support. + * Added wait helper for X550 IOSF accesses. + * Added X550em features. + * Added X557 PHY LEDs support. + * Commands for flow director. + * Issue firmware command when resetting X550em. + + See the git log for full details of the ixgbe/base changes. + + +* **Added additional hotplug support.** + + Port hotplug support was added to the following PMDs: + + * e1000/igb. + * ixgbe. + * i40e. + * fm10k. + * ring. + * bonding. + * virtio. + + Port hotplug support was added to BSD. + + +* **Added ixgbe LRO support.** + + Added LRO support for x540 and 82599 devices. + + +* **Added extended statistics for ixgbe.** + + Implemented ``xstats_get()`` and ``xstats_reset()`` in dev_ops for + ixgbe to expose detailed error statistics to DPDK applications. + + These will be implemented for other PMDs in later releases. + + +* **Added proc_info application.** + + Created a new ``proc_info`` application, by refactoring the existing + ``dump_cfg`` application, to demonstrate the usage of retrieving statistics, + and the new extended statistics (see above), for DPDK interfaces. + + +* **Updated the i40e base driver.** + + The i40e base driver was updated with several changes including the + following: + + * Support for building both PF and VF driver together. + * Support for CEE DCBX on recent firmware versions. + * Replacement of ``i40e_debug_read_register()``. + * Rework of ``i40e_hmc_get_object_va``. + * Update of shadow RAM read/write functions. + * Enhancement of polling NVM semaphore. + * Enhancements on adminq init and sending asq command. + * Update of get/set LED functions. + * Addition of AOC phy types to case statement in get_media_type. + * Support for iSCSI capability. + * Setting of FLAG_RD when sending driver version to FW. + + See the git log for full details of the i40e/base changes. + + +* **Added support for port mirroring in i40e.** + + Enabled mirror functionality in the i40e driver. + + +* **Added support for i40e double VLAN, QinQ, stripping and insertion.** + + Added support to the i40e driver for offloading double VLAN (QinQ) tags to + the mbuf header, and inserting double vlan tags by hardware to the packets + to be transmitted. Added a new field ``vlan_tci_outer`` in the ``rte_mbuf`` + struct, and new flags in ``ol_flags`` to support this feature. + + + +* **Added fm10k promiscuous mode support.** + + Added support for promiscuous/allmulticast enable and disable in the fm10k PF + function. VF is not supported yet. + + +* **Added fm10k jumbo frame support.** + + Added support for jumbo frame less than 15K in both VF and PF functions in the + fm10k pmd. + + +* **Added fm10k mac vlan filtering support.** + + Added support for the fm10k MAC filter, only available in PF. Updated the + VLAN filter to add/delete one static entry in the MAC table for each + combination of VLAN and MAC address. + + +* **Added support for the Broadcom bnx2x driver.** + + Added support for the Broadcom NetXtreme II bnx2x driver. + It is supported only on Linux 64-bit and disabled by default. + + +* **Added support for the Chelsio CXGBE driver.** + + Added support for the CXGBE Poll Mode Driver for the Chelsio Terminator 5 + series of 10G/40G adapters. + + +* **Enhanced support for Mellanox ConnectX-3 driver (mlx4).** + + * Support Mellanox OFED 3.0. + * Improved performance for both RX and TX operations. + * Better link status information. + * Outer L3/L4 checksum offload support. + * Inner L3/L4 checksum offload support for VXLAN. + + +* **Enabled VMXNET3 vlan filtering.** + + Added support for the VLAN filter functionality of the VMXNET3 interface. + + +* **Added support for vhost live migration.** + + Added support to allow live migration of vhost. Without this feature, qemu + will report the following error: "migrate: Migration disabled: vhost lacks + VHOST_F_LOG_ALL feature". + + +* **Added support for pcap jumbo frames.** + + Extended the PCAP PMD to support jumbo frames for RX and TX. + + +* **Added support for the TILE-Gx architecture.** + + Added support for the EZchip TILE-Gx family of SoCs. + + +* **Added hardware memory transactions/lock elision for x86.** + + Added the use of hardware memory transactions (HTM) on fast-path for rwlock + and spinlock (a.k.a. lock elision). The methods are implemented for x86 + using Restricted Transactional Memory instructions (Intel(r) Transactional + Synchronization Extensions). The implementation fall-backs to the normal + rwlock if HTM is not available or memory transactions fail. This is not a + replacement for all rwlock usages since not all critical sections protected + by locks are friendly to HTM. For example, an attempt to perform a HW I/O + operation inside a hardware memory transaction always aborts the transaction + since the CPU is not able to roll-back should the transaction + fail. Therefore, hardware transactional locks are not advised to be used + around ``rte_eth_rx_burst()`` and ``rte_eth_tx_burst()`` calls. + + +* **Updated Jenkins Hash function** + + Updated the version of the Jenkins Hash (jhash) function used in DPDK from + the 1996 version to the 2006 version. This gives up to 35% better + performance, compared to the original one. + + Note, the hashes generated by the updated version differ from the hashes + generated by the previous version. + + +* **Added software implementation of the Toeplitz RSS hash** + + Added a software implementation of the Toeplitz hash function used by RSS. It + can be used either for packet distribution on a single queue NIC or for + simulating RSS computation on a specific NIC (for example after GRE header + de-encapsulation). + + +* **Replaced the existing hash library with a Cuckoo hash implementation.** + + Replaced the existing hash library with another approach, using the Cuckoo + Hash method to resolve collisions (open addressing). This method pushes + items from a full bucket when a new entry must be added to it, storing the + evicted entry in an alternative location, using a secondary hash function. + + This gives the user the ability to store more entries when a bucket is full, + in comparison with the previous implementation. + + The API has not been changed, although new fields have been added in the + ``rte_hash`` structure, which has been changed to internal use only. + + The main change when creating a new table is that the number of entries per + bucket is now fixed, so its parameter is ignored now (it is still there to + maintain the same parameters structure). + + Also, the maximum burst size in lookup_burst function hash been increased to + 64, to improve performance. + + +* **Optimized KNI RX burst size computation.** + + Optimized KNI RX burst size computation by avoiding checking how many + entries are in ``kni->rx_q`` prior to actually pulling them from the fifo. + + +* **Added KNI multicast.** + + Enabled adding multicast addresses to KNI interfaces by adding an empty + callback for ``set_rx_mode`` (typically used for setting up hardware) so + that the ioctl succeeds. This is the same thing as the Linux tap interface + does. + + +* **Added cmdline polling mode.** + + Added the ability to process console input in the same thread as packet + processing by using the ``poll()`` function. + +* **Added VXLAN Tunnel End point sample application.** + + Added a Tunnel End point (TEP) sample application that simulates a VXLAN + Tunnel Endpoint (VTEP) termination in DPDK. It is used to demonstrate the + offload and filtering capabilities of Intel XL710 10/40 GbE NICsfor VXLAN + packets. + + +* **Enabled combining of the ``-m`` and ``--no-huge`` EAL options.** + + Added option to allow combining of the ``-m`` and ``--no-huge`` EAL command + line options. + + This allows user application to run as non-root but with higher memory + allocations, and removes a constraint on ``--no-huge`` mode being limited to + 64M. + + + +Resolved Issues +--------------- + +* **acl: Fix ambiguity between test rules.** + + Some test rules had equal priority for the same category. That could cause + an ambiguity in building the trie and test results. + + +* **acl: Fix invalid rule wildness calculation for bitmask field type.** + + +* **acl: Fix matching rule.** + + +* **acl: Fix unneeded trie splitting for subset of rules.** + + When rebuilding a trie for limited rule-set, don't try to split the rule-set + even further. + + +* **app/testpmd: Fix crash when port id out of bound.** + + Fixed issues in testpmd where using a port greater than 32 would cause a seg + fault. + + Fixes: edab33b1c01d ("app/testpmd: support port hotplug") + + +* **app/testpmd: Fix reply to a multicast ICMP request.** + + Set the IP source and destination addresses in the IP header of the ICMP + reply. + + +* **app/testpmd: fix MAC address in ARP reply.** + + Fixed issue where in the ``icmpecho`` forwarding mode, ARP replies from + testpmd contain invalid zero-filled MAC addresses. + + Fixes: 31db4d38de72 ("net: change arp header struct declaration") + + +* **app/testpmd: fix default flow control values.** + + Fixes: 422a20a4e62d ("app/testpmd: fix uninitialized flow control variables") + + +* **bonding: Fix crash when stopping inactive slave.** + + +* **bonding: Fix device initialization error handling.** + + +* **bonding: Fix initial link status of slave.** + + On Fortville NIC, link status change interrupt callback was not executed + when slave in bonding was (re-)started. + + +* **bonding: Fix socket id for LACP slave.** + + Fixes: 46fb43683679 ("bond: add mode 4") + + +* **bonding: Fix device initialization error handling.** + + +* **cmdline: Fix small memory leak.** + + A function in ``cmdline.c`` had a return that did not free the buf properly. + + +* **config: Enable same drivers options for Linux and BSD.** + + Enabled vector ixgbe and i40e bulk alloc for BSD as it is already done for + Linux. + + Fixes: 304caba12643 ("config: fix bsd options") + Fixes: 0ff3324da2eb ("ixgbe: rework vector pmd following mbuf changes") + + +* **devargs: Fix crash on failure.** + + This problem occurred when passing an invalid PCI id to the blacklist API in + devargs. + + +* **e1000/i40e: Fix descriptor done flag with odd address.** + + +* **e1000/igb: fix ieee1588 timestamping initialization.** + + Fixed issue with e1000 ieee1588 timestamp initialization.

The driver + switched back from page 1 to page 0 too soon, before + ``e1000_check_for_link_82575()`` is executed and was never finding the link + on the fiber (other). + + If the link is copper, as the M88E1112 page address is set to 1, it should be + set back to 0 before checking this link. + +* **e1000/base: Fix beacon duration for i217.** + + Fix for I217 Packet Loss issue - The Management Engine sets the FEXTNVM4 + Beacon Duration incorrectly. This fix ensures that the correct value will + always be set. Correct value for this field is 8 usec. + +* **e1000/base: Fix TIPG for non 10 half duplex mode.** + + TIPG value is increased when setting speed to 10 half duplex to prevent + packet loss. However, it was never decreased again when speed + changed. This caused performance issues in the NDIS driver. + Fix this to restore TIPG to default value on non 10 half duplex. + +* **e1000/base: Fix reset of DH89XXCC SGMII.** + + For DH89XXCC_SGMII, a write flush leaves registers of this device trashed + (0xFFFFFFFF). Add check for this device. + + Also, after both Port SW Reset and Device Reset case, the platform should + wait at least 3ms before reading any registers. Remove this condition since + waiting is conditionally executed only for Device Reset. + +* **e1000/base: Fix redundant PHY power down for i210.** + + Bit 11 of PHYREG 0 is used to power down PHY. The use of PHYREG 16 is + no longer necessary. + +* **e1000/base: fix jumbo frame CRC failures.** + + Change the value of register 776.20[11:2] for jumbo mode from 0x1A to 0x1F. + This is to enlarge the gap between read and write pointers in the TX FIFO. + +* **e1000/base: Fix link flap on 82579.** + + Several customers have reported a link flap issue on 82579. The symptoms + are random and intermittent link losses when 82579 is connected to specific + switches. the Issue was root caused as an inter-operability problem between + the NIC and at least some Broadcom PHYs in the Energy Efficient Ethernet + wake mechanism. + + To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M + Low Power Idle. This solution will cause an increase of power in 100M EEE + link. It may cost an additional 28mW in this specific mode. + +* **igb: Fixed IEEE1588 frame identification in I210.** + + Fixed issue where the flag ``PKT_RX_IEEE1588_PTP`` was not being set + in the Intel I210 NIC, as the EtherType in RX descriptor is in bits 8:10 of + Packet Type and not in the default bits 0:2. + +* **igb: Fixed VF start with PF stopped.** + + VF needs the PF interrupt support initialized even if not started. + +* **igb: Fixed VF MAC address when using with DPDK PF.** + + Assign a random MAC address in VF when not assigned by PF. + +* **igb: Removed CRC bytes from byte counter statistics.** + +* **ixgbe: Fixed issue with X550 DCB.** + + Fixed a DCB issue with x550 where for 8 TCs (Traffic Classes), if a packet + with user priority 6 or 7 was injected to the NIC, then the NIC would only + put 3 packets into the queue. There was also a similar issue for 4 TCs. + +* **ixgbe: Removed burst size restriction of vector RX.** + + Fixed issue where a burst size less than 32 didn't receive anything. + +* **ixgbe: Fixed VF start with PF stopped.** + + VF needs the PF interrupt support initialized even if not started. + +* **ixgbe: Fixed TX hang when RS distance exceeds HW limit.** + + Fixed an issue where the TX queue can hang when a lot of highly fragmented + packets have to be sent. As part of that fix, ``tx_rs_thresh`` for ixgbe PMD + is not allowed to be greater then to 32 to comply with HW restrictions. + +* **ixgbe: Fixed rx error statistic counter.** + + Fixed an issue that the rx error counter of ixgbe was not accurate. The + mac short packet discard count (mspdc) was added to the counter. Mac local + faults and mac remote faults are removed as they do not count packets but + errors, and jabber errors were removed as they are already accounted for + by the CRC error counter. Finally the XEC (l3 / l4 checksum error) counter + was removed due to errata, see commit 256ff05a9cae for details. + +* **ixgbe: Removed CRC bytes from byte counter statistics.** + +* **i40e: Fixed base driver allocation when not using first numa node.** + + Fixed i40e issue that occurred when a DPDK application didn't initialize + ports if memory wasn't available on socket 0. + +* **i40e: Fixed maximum of 64 queues per port.** + + Fixed an issue in i40e where it would not support more than 64 queues per + port, even though the hardware actually supports it. The real number of + queues may vary, as long as the total number of queues used in PF, VFs, VMDq + and FD does not exceeds the hardware maximum. + +* **i40e: Fixed statistics of packets.** + + Added discarding packets on VSI to the stats and rectify the old statistics. + +* **i40e: Fixed issue of not freeing memzone.** + + Fixed an issue of not freeing a memzone in the call to free the memory for + adminq DMA. + +* **i40e: Removed CRC bytes from byte counter statistics.** + +* **mlx: Fixed driver loading.** + + The mlx drivers were unable to load when built as a shared library, + due to a missing symbol in the mempool library. + +* **mlx4: Performance improvements.** + + Fixed bugs in TX and RX flows that improves mlx4 performance. + +* **mlx4: Fixed TX loss after initialization.** + +* **mlx4: Fixed scattered TX with too many segments.** + +* **mlx4: Fixed memory registration for indirect mbuf data.** + +* **vhost: Fixed Qemu shutdown.** + + Fixed issue with libvirt ``virsh destroy`` not killing the VM. + +* **virtio: Fixed crash after changing link state.** + + Fixed IO permission in the interrupt handler. + +* **virtio: Fixed crash when releasing queue.** + + Fixed issue when releasing null control queue. + + +Libraries +~~~~~~~~~ + +* **hash: Fixed memory allocation of Cuckoo Hash key table.** + + Fixed issue where an incorrect Cuckoo Hash key table size could be + calculated limiting the size to 4GB. + +* **hash: Fixed incorrect lookup if key is all zero.** + + Fixed issue in hash library that occurred if an all zero + key was not added to the table and the key was looked up, + resulting in an incorrect hit. + +* **hash: Fixed thread scaling by reducing contention.** + + Fixed issue in the hash library where, using multiple cores with + hardware transactional memory support, thread scaling did not work, + due to the global ring that is shared by all cores. + + +Examples +~~~~~~~~ + +* **l3fwd: Fixed crash with IPv6.** + +* **vhost_xen: Fixed compile error.** + + +Other +~~~~~ + +* This release drops compatibility with Linux kernel 2.6.33. The minimum + kernel requirement is now 2.6.34. + + +Known Issues +------------ + +* Some drivers do not fill in the packet type when receiving. + As the l3fwd example application requires this info, the i40e vector + driver must be disabled to benefit of the packet type with i40e. + +* Some (possibly all) VF drivers (e.g. i40evf) do not handle any PF reset + events/requests in the VF driver. This means that the VF driver may not work + after a PF reset in the host side. The workaround is to avoid triggering any + PF reset events/requests on the host side. + +* 100G link report support is missing. + +* **Mellanox PMDs (mlx4 & mlx5):** + + * PMDs do not support CONFIG_RTE_BUILD_COMBINE_LIBS and + CONFIG_RTE_BUILD_SHARED_LIB simultaneously. + + * There is performance degradation for small packets when the PMD is + compiled with ``SGE_WR_N = 4`` compared to the performance when ``SGE_WR_N + = 1``. If scattered packets are not used it is recommended to compile the + PMD with ``SGE_WR_N = 1``. + + * When a Multicast or Broadcast packet is sent to the SR-IOV mlx4 VF, + it is returned back to the port. + + * PMDs report "bad" L4 checksum when IP packet is received. + + * mlx5 PMD reports "bad" checksum although the packet has "good" checksum. + Will be fixed in upcoming MLNX_OFED release. + + +API Changes +----------- + +* The deprecated flow director API is removed. + It was replaced by ``rte_eth_dev_filter_ctrl()``. + +* The ``dcb_queue`` is renamed to ``dcb_tc`` in following dcb configuration + structures: ``rte_eth_dcb_rx_conf``, ``rte_eth_dcb_tx_conf``, + ``rte_eth_vmdq_dcb_conf``, ``rte_eth_vmdq_dcb_tx_conf``. + +* The ``rte_eth_rx_queue_count()`` function now returns "int" instead of + "uint32_t" to allow the use of negative values as error codes on return. + +* The function ``rte_eal_pci_close_one()`` is removed. + It was replaced by ``rte_eal_pci_detach()``. + +* The deprecated ACL API ``ipv4vlan`` is removed. + +* The deprecated hash function ``rte_jhash2()`` is removed. + It was replaced by ``rte_jhash_32b()``. + +* The deprecated KNI functions are removed: + ``rte_kni_create()``, ``rte_kni_get_port_id()`` and ``rte_kni_info_get()``. + +* The deprecated ring PMD functions are removed: + ``rte_eth_ring_pair_create()`` and ``rte_eth_ring_pair_attach()``. + +* The devargs union field ``virtual`` is renamed to ``virt`` for C++ + compatibility. + + +ABI Changes +----------- + +* The EAL and ethdev structures ``rte_intr_handle`` and ``rte_eth_conf`` were + changed to support RX interrupt. This was already included in 2.1 under the + ``CONFIG_RTE_NEXT_ABI`` #define. + +* The ethdev flow director entries for SCTP were changed. + This was already included in 2.1 under the ``CONFIG_RTE_NEXT_ABI`` #define. + +* The ethdev flow director structure ``rte_eth_fdir_flow_ext`` structure was + changed.

+ +Each command (of type cmdline_parse_inst_t) is defined statically. +It contains a pointer to a callback function that is executed when the command is parsed, +an opaque pointer, a help string and a list of tokens in a NULL-terminated table. + +The rte_cmdline application provides a list of pre-defined token types: + +* String Token: Match a static string, a list of static strings or any string. + +* Number Token: Match a number that can be signed or unsigned, from 8-bit to 32-bit. + +* IP Address Token: Match an IPv4 or IPv6 address or network. + +* Ethernet* Address Token: Match a MAC address. + +In this example, a new token type obj_list is defined and implemented +in the parse_obj_list.c and parse_obj_list.h files. + +For example, the cmd_obj_del_show command is defined as shown below: + +.. code-block:: c + + struct cmd_obj_add_result { + cmdline_fixed_string_t action;

To run the application in linuxapp environment with 10 lcores, 4 ports, + issue the command: + + .. code-block:: console + + $ ./build/distributor_app -l 1-9,22 -n 4 -- -p f + +#. Refer to the DPDK Getting Started Guide for general information on running + applications and the Environment Abstraction Layer (EAL) options. + +Explanation +----------- + +The distributor application consists of four types of threads: a receive +thread (``lcore_rx()``), a distributor thread (``lcore_dist()``), a set of +worker threads (``lcore_worker()``), and a transmit thread(``lcore_tx()``). +How these threads work together is shown in :numref:`figure_dist_app` below. +The ``main()`` function launches threads of these four types. Each thread +has a while loop which will be doing processing and which is terminated +only upon SIGINT or ctrl+C. + +The receive thread receives the packets using ``rte_eth_rx_burst()`` and will +enqueue them to an rte_ring. The distributor thread will dequeue the packets +from the ring and assign them to workers (using ``rte_distributor_process()`` API). +This assignment is based on the tag (or flow ID) of the packet - indicated by +the hash field in the mbuf. For IP traffic, this field is automatically filled +by the NIC with the "usr" hash value for the packet, which works as a per-flow +tag. The distributor thread communicates with the worker threads using a +cache-line swapping mechanism, passing up to 8 mbuf pointers at a time +(one cache line) to each worker. + +More than one worker thread can exist as part of the application, and these +worker threads do simple packet processing by requesting packets from +the distributor, doing a simple XOR operation on the input port mbuf field +(to indicate the output port which will be used later for packet transmission) +and then finally returning the packets back to the distributor thread. + +The distributor thread will then call the distributor api +``rte_distributor_returned_pkts()`` to get the processed packets, and will enqueue +them to another rte_ring for transfer to the TX thread for transmission on the +output port. The transmit thread will dequeue the packets from the ring and +transmit them on the output port specified in packet mbuf. + +Users who wish to terminate the running of the application have to press ctrl+C +(or send SIGINT to the app). Upon this signal, a signal handler provided +in the application will terminate all running threads gracefully and print +final statistics to the user. + +.. _figure_dist_app: + +.. figure:: img/dist_app.* + + Distributor Sample Application Layout + + +Debug Logging Support +--------------------- + +Debug logging is provided as part of the application; the user needs to uncomment +the line "#define DEBUG" defined in start of the application in main.c to enable debug logs. + +Statistics +---------- + +The main function will print statistics on the console every second. These +statistics include the number of packets enqueued and dequeued at each stage +in the application, and also key statistics per worker, including how many +packets of each burst size (1-8) were sent to each worker thread. + +Application Initialization +-------------------------- + +Command line parsing is done in the same way as it is done in the L2 Forwarding Sample +Application.

Some of the more interesting +examples are highlighted below. + + +* :doc:`Hello World`: As with most introductions to a + programming framework a good place to start is with the Hello World + application. The Hello World example sets up the DPDK Environment Abstraction + Layer (EAL), and prints a simple "Hello World" message to each of the DPDK + enabled cores. This application doesn't do any packet forwarding but it is a + good way to test if the DPDK environment is compiled and set up properly. + +* :doc:`Basic Forwarding/Skeleton Application`: The Basic + Forwarding/Skeleton contains the minimum amount of code required to enable + basic packet forwarding with DPDK. This allows you to test if your network + interfaces are working with DPDK. + +* :doc:`Network Layer 2 forwarding`: The Network Layer 2 + forwarding, or ``l2fwd`` application does forwarding based on Ethernet MAC + addresses like a simple switch. + +* :doc:`Network Layer 3 forwarding`: The Network Layer3 + forwarding, or ``l3fwd`` application does forwarding based on Internet + Protocol, IPv4 or IPv6 like a simple router. + +* :doc:`Packet Distributor`: The Packet Distributor + demonstrates how to distribute packets arriving on an Rx port to different + cores for processing and transmission. + +* :doc:`Multi-Process Application`: The + multi-process application shows how two DPDK processes can work together using + queues and memory pools to share information. + +* :doc:`RX/TX callbacks Application`: The RX/TX + callbacks sample application is a packet forwarding application that + demonstrates the use of user defined callbacks on received and transmitted + packets. The application calculates the latency of a packet between RX + (packet arrival) and TX (packet transmission) by adding callbacks to the RX + and TX packet processing functions. + +* :doc:`IPSec Security Gateway`: The IPSec Security + Gateway application is minimal example of something closer to a real world + example. This is also a good example of an application using the DPDK + Cryptodev framework. + +* :doc:`Precision Time Protocol (PTP) client`: The PTP + client is another minimal implementation of a real world application. + In this case the application is a PTP client that communicates with a PTP + master clock to synchronize time on a Network Interface Card (NIC) using the + IEEE1588 protocol. + +* :doc:`Quality of Service (QoS) Scheduler`: The QoS + Scheduler application demonstrates the use of DPDK to provide QoS scheduling. + +There are many more examples shown in the following chapters. Each of the +documented sample applications show how to compile, configure and run the +application as well as explaining the main functionality of the code. diff --git a/dpdk/doc/guides/sample_app_ug/ip_frag.rst b/dpdk/doc/guides/sample_app_ug/ip_frag.rst new file mode 100644 index 0000000..7914a97 --- /dev/null +++ b/dpdk/doc/guides/sample_app_ug/ip_frag.rst @@ -0,0 +1,140 @@ +..

By loading a different configuration file, a different application is +effectively started. + + +Flexibility +~~~~~~~~~~~ + +Each packet processing application is typically represented as a chain of functional stages which is often called +the functional pipeline of the application. +These stages are mapped to CPU cores to create chains of CPU cores (pipeline model), clusters of CPU cores +(run-to-completion model) or chains of clusters of CPU cores (hybrid model). + +This application allows all the above programming models. +By applying changes to the configuration file, the application provides the flexibility to reshuffle its +building blocks in different ways until the configuration providing the best performance is identified. + + +Move pipelines around +^^^^^^^^^^^^^^^^^^^^^ + +The mapping of pipeline instances to CPU cores can be reshuffled through the configuration file. +One or several pipeline instances can be mapped to the same CPU core. + +.. _figure_ip_pipelines_1: + +.. figure:: img/ip_pipelines_1.* + + Example of moving pipeline instances across different CPU cores + + +Move tables around +^^^^^^^^^^^^^^^^^^ + +There is some degree of flexibility for moving tables from one pipeline instance to another. +Based on the configuration arguments passed to each pipeline instance in the configuration file, specific tables +can be enabled or disabled. +This way, a specific table can be “moved” from pipeline instance A to pipeline instance B by simply disabling its +associated functionality for pipeline instance A while enabling it for pipeline instance B. + +Due to requirement to have simple syntax for the configuration file, moving tables across different pipeline +instances is not as flexible as the mapping of pipeline instances to CPU cores, or mapping actions to pipeline tables. +Complete flexibility in moving tables from one pipeline to another could be achieved through a complex pipeline +description language that would detail the structural elements of the pipeline (ports, tables and actions) and +their connectivity, resulting in complex syntax for the configuration file, which is not acceptable. +Good configuration file readability through simple syntax is preferred. + +*Example*: the IP routing pipeline can run the routing function only (with ARP function run by a different +pipeline instance), or it can run both the routing and ARP functions as part of the same pipeline instance. + + +.. _figure_ip_pipelines_2: + +.. figure:: img/ip_pipelines_2.* + + Example of moving tables across different pipeline instances + + +Move actions around +^^^^^^^^^^^^^^^^^^^ + +When it makes sense, packet processing actions can be moved from one pipeline instance to another. +Based on the configuration arguments passed to each pipeline instance in the configuration file, specific actions +can be enabled or disabled. +This way, a specific action can be "moved" from pipeline instance A to pipeline instance B by simply disabling its +associated functionality for pipeline instance A while enabling it for pipeline instance B. + +*Example*: The flow actions of accounting, traffic metering, application identification, NAT, etc can be run as part +of the flow classification pipeline instance or split across several flow actions pipeline instances, depending on +the number of flow instances and their compute requirements. + + +.. _figure_ip_pipelines_3: + +.. figure:: img/ip_pipelines_3.* + + Example of moving actions across different tables and pipeline instances + + +Performance +~~~~~~~~~~~ + +Performance of the application is the highest priority requirement. +Flexibility is not provided at the expense of performance. + +The purpose of flexibility is to provide an incremental development methodology that allows monitoring the +performance evolution: + +* Apply incremental changes in the configuration (e.g. mapping on pipeline instances to CPU cores) + in order to identify the configuration providing the best performance for a given application; + +* Add more processing incrementally (e.g. by enabling more actions for specific pipeline instances) until + the application is feature complete while checking the performance impact at each step. + + +Debug capabilities +~~~~~~~~~~~~~~~~~~ + +The application provides a significant set of debug capabilities: + +* Command Line Interface (CLI) support for statistics polling: pipeline instance ping (keep-alive checks), + pipeline instance statistics per input port/output port/table, link statistics, etc; + +* Logging: Turn on/off application log messages based on priority level; + +Running the application +----------------------- + +The application startup command line is:: + + ip_pipeline [-f CONFIG_FILE] [-s SCRIPT_FILE] -p PORT_MASK [-l LOG_LEVEL] + +The application startup arguments are: + +``-f CONFIG_FILE`` + + * Optional: Yes + + * Default: ``./config/ip_pipeline.cfg`` + + * Argument: Path to the configuration file to be loaded by the application. + Please refer to the :ref:`ip_pipeline_configuration_file` for details on how to write the configuration file. + +``-s SCRIPT_FILE`` + + * Optional: Yes + + * Default: Not present + + * Argument: Path to the CLI script file to be run by the master pipeline at application startup. + No CLI script file will be run at startup if this argument is not present. + +``-p PORT_MASK`` + + * Optional: No + + * Default: N/A + + * Argument: Hexadecimal mask of NIC port IDs to be used by the application. + First port enabled in this mask will be referenced as LINK0 as part of the application configuration file, + next port as LINK1, etc. + +``-l LOG_LEVEL`` + + * Optional: Yes + + * Default: 1 (High priority) + + * Argument: Log level to determine which application messages are to be printed to standard output. + Available log levels are: 0 (None), 1 (High priority), 2 (Low priority). + Only application messages whose priority is higher than or equal to the application log level will be printed. + + +Application stages +------------------ + + +Configuration +~~~~~~~~~~~~~ + +During this stage, the application configuration file is parsed and its content is loaded into the application data +structures. +In case of any configuration file parse error, an error message is displayed and the application is terminated. +Please refer to the :ref:`ip_pipeline_configuration_file` for a description of the application configuration file format. + + +Configuration checking +~~~~~~~~~~~~~~~~~~~~~~ + +In the absence of any parse errors, the loaded content of application data structures is checked for overall consistency. +In case of any configuration check error, an error message is displayed and the application is terminated. + + +Initialization +~~~~~~~~~~~~~~ + +During this stage, the application resources are initialized and the handles to access them are saved into the +application data structures. +In case of any initialization error, an error message is displayed and the application is terminated. + +The typical resources to be initialized are: pipeline instances, buffer pools, links (i.e. network interfaces), +hardware device RX/TX queues, software queues, traffic management devices, etc. + + +.. _ip_pipeline_runtime: + +Run-time +~~~~~~~~ + +Each CPU core runs the pipeline instances assigned to it in time sharing mode and in round robin order: + +1. *Packet processing task*: The pipeline run-time code is typically a packet *processing* task built on top of + DPDK Packet Framework rte_pipeline library, which reads bursts of packets from the pipeline input ports, + performs table lookups and executes the identified actions for all tables in the pipeline, with packet + eventually written to pipeline output ports or dropped. + +2. *Message handling task*: Each CPU core will also periodically execute the *message handling* code of each + of the pipelines mapped to it. + The pipeline message handling code is processing the messages that are pending in the pipeline input message + queues, which are typically sent by the master CPU core for the on-the-fly pipeline configuration: check + that pipeline is still alive (ping), add/delete entries in the pipeline tables, get statistics, etc. + The frequency of executing the message handling code is usually much smaller than the frequency of executing + the packet processing work. + +Please refer to the :ref:`ip_pipeline_pipeline_section` for more details about the application pipeline module encapsulation. + +.. _ip_pipeline_configuration_file: + +Configuration file syntax +------------------------- + +Syntax overview +~~~~~~~~~~~~~~~ + +The syntax of the configuration file is designed to be simple, which favors readability. +The configuration file is parsed using the DPDK library librte_cfgfile, which supports simple +`INI file format `__ for configuration files. + +As result, the configuration file is split into several sections, with each section containing one or more entries. +The scope of each entry is its section, and each entry specifies a variable that is assigned a specific value. +Any text after the ``;`` character is considered a comment and is therefore ignored. + +The following are application specific: number of sections, name of each section, number of entries of each section, +name of the variables used for each section entry, the value format (e.g. signed/unsigned integer, string, etc) +and range of each section entry variable. + +Generic example of configuration file section: + +.. code-block:: ini + + [] + + = + + ;

Application resource name determines the type of resource based on the name prefix. + + *Example*: all software queues need to start with ``SWQ`` prefix, so ``SWQ0`` and ``SWQ5`` are valid software + queue names. + +2. An application resource is defined by creating a configuration file section with its name. + The configuration file section allows fine tuning on any of the resource parameters. + Some resource parameters are mandatory, in which case it is required to have them specified as part of the + section, while some others are optional, in which case they get assigned their default value when not present. + + *Example*: section ``SWQ0`` defines a software queue named SWQ0, whose parameters are detailed as part of this section. + +3. An application resource can also be defined by referencing it. + Referencing a resource takes place by simply using its name as part of the value assigned to a variable in any + configuration file section. + In this case, the resource is registered with all its parameters having their default values. + Optionally, a section with the resource name can be added to the configuration file to fine tune some or all + of the resource parameters. + + *Example*: in section ``PIPELINE3``, variable ``pktq_in`` includes ``SWQ5`` as part of its list, which results + in defining a software queue named ``SWQ5``; when there is no ``SWQ5`` section present in the configuration file, + ``SWQ5`` gets registered with default parameters. + + +.. _ip_pipeline_pipeline_section: + +PIPELINE section +~~~~~~~~~~~~~~~~ + +.. _table_ip_pipelines_pipeline_section_1: + +.. tabularcolumns:: |p{2.5cm}|p{7cm}|p{1.5cm}|p{1.5cm}|p{1.5cm}| + +.. table:: Configuration file PIPELINE section (1/2) + + +---------------+-----------------------------------------------------------+---------------+------------------------+----------------+ + | Section | Description | Optional | Range | Default value | + +===============+===========================================================+===============+========================+================+ + | type | Pipeline type.

The back-end represents the packet processing engine +of the pipeline, typically implemented using the DPDK Packet Framework libraries, which reads packets from the +input packet queues, handles them and eventually writes them to the output packet queues or drops them. +The front-end represents the run-time configuration interface of the pipeline, which is exposed as CLI commands. +The front-end communicates with the back-end through message queues. + +.. _table_ip_pipelines_back_end: + +.. tabularcolumns:: |p{1cm}|p{2cm}|p{12cm}| + +.. table:: Pipeline back-end + + +------------+------------------+--------------------------------------------------------------------+ + | Field name | Field type | Description | + +============+==================+====================================================================+ + | f_init | Function pointer | Function to initialize the back-end of the current pipeline | + | | | instance.

Pure meta-data: intermediate data per packet that is computed internally, passed between different tables of + the same pipeline instance (e.g. lookup key for the ARP table is obtained from the routing table), or between + different pipeline instances (e.g. flow ID, traffic metering color, etc); + +2. Packet fields: typically, packet header fields that are read directly from the packet, or read from the packet + and saved (duplicated) as a working copy at a different location within the packet meta-data (e.g. Diffserv + 5-tuple, IP destination address, etc). + +Several strategies are used to design the packet meta-data, as described in the next subsections. + + +Store packet meta-data in a different cache line as the packet headers +"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" + +This approach is able to support protocols with variable header length, like MPLS, where the offset of IP header +from the start of the packet (and, implicitly, the offset of the IP header in the packet buffer) is not fixed. +Since the pipelines typically require the specification of a fixed offset to the packet fields (e.g. Diffserv +5-tuple, used by the flow classification pipeline, or the IP destination address, used by the IP routing pipeline), +the workaround is to have the packet RX pipeline copy these fields at fixed offsets within the packet meta-data. + +As this approach duplicates some of the packet fields, it requires accessing more cache lines per packet for filling +in selected packet meta-data fields (on RX), as well as flushing selected packet meta-data fields into the +packet (on TX). + +Example: + +.. code-block:: ini + + + ; struct app_pkt_metadata { + ; uint32_t ip_da; + ; uint32_t hash; + ; uint32_t flow_id; + ; uint32_t color; + ; } __attribute__((__packed__)); + ; + + [PIPELINE1] + ; Packet meta-data offsets + ip_da_offset = 0; Used by: routing + hash_offset = 4; Used by: RX, flow classification + flow_id_offset = 8; Used by: flow classification, flow actions + color_offset = 12; Used by: flow actions, routing + + +Overlay the packet meta-data in the same cache line with the packet headers +""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""" + +This approach is minimizing the number of cache line accessed per packet by storing the packet metadata in the +same cache line with the packet headers. +To enable this strategy, either some headroom is reserved for meta-data at the beginning of the packet headers +cache line (e.g. if 16 bytes are needed for meta-data, then the packet headroom can be set to 128+16 bytes, so +that NIC writes the first byte of the packet at offset 16 from the start of the first packet cache line), +or meta-data is reusing the space of some packet headers that are discarded from the packet (e.g. input Ethernet +header). + +Example: + +.. code-block:: ini + + ; struct app_pkt_metadata { + ; uint8_t headroom[RTE_PKTMBUF_HEADROOM]; /* 128 bytes (default) */ + ; union { + ; struct { + ; struct ether_hdr ether; /* 14 bytes */ + ; struct qinq_hdr qinq; /* 8 bytes */ + ; }; + ; struct { + ; uint32_t hash; + ; uint32_t flow_id; + ; uint32_t color; + ; }; + ; }; + ; struct ipv4_hdr ip; /* 20 bytes */ + ; } __attribute__((__packed__)); + ; + [PIPELINE2] + ; Packet meta-data offsets + qinq_offset = 142; Used by: RX, flow classification + ip_da_offset = 166; Used by: routing + hash_offset = 128; Used by: RX, flow classification + flow_id_offset = 132; Used by: flow classification, flow actions + color_offset = 136; Used by: flow actions, routing + + +List of pipeline types +~~~~~~~~~~~~~~~~~~~~~~ + +.. _table_ip_pipelines_types: + +.. tabularcolumns:: |p{3cm}|p{5cm}|p{4cm}|p{4cm}| + +.. table:: List of pipeline types provided with the application + + +-----------------------+-----------------------------+-----------------------+------------------------------------------+ + | Name | Table(s) | Actions | Messages | + +=======================+=============================+=======================+==========================================+ + | Pass-through | Passthrough | 1.

Please refer to Programmer's Guide for more detailed explanation of how to use this library. +Fragment table maintains information about already received fragments of the packet. +Each IP packet is uniquely identified by triple , , . +To avoid lock contention, each RX queue has its own Fragment Table, +e.g. the application can't handle the situation when different fragments of the same packet arrive through different RX queues. +Each table entry can hold information about packet consisting of up to RTE_LIBRTE_IP_FRAG_MAX_FRAGS fragments. + +.. code-block:: c + + frag_cycles = (rte_get_tsc_hz() + MS_PER_S - 1) / MS_PER_S * max_flow_ttl; + + if ((qconf->frag_tbl[queue] = rte_ip_frag_tbl_create(max_flow_num, IPV4_FRAG_TBL_BUCKET_ENTRIES, max_flow_num, frag_cycles, socket)) == NULL) + { + RTE_LOG(ERR, IP_RSMBL, "ip_frag_tbl_create(%u) on " "lcore: %u for queue: %u failed\n", max_flow_num, lcore, queue); + return -1; + } + +Mempools Initialization +~~~~~~~~~~~~~~~~~~~~~~~ + +The reassembly application demands a lot of mbuf's to be allocated. +At any given time up to (2 \* max_flow_num \* RTE_LIBRTE_IP_FRAG_MAX_FRAGS \* ) +can be stored inside Fragment Table waiting for remaining fragments. +To keep mempool size under reasonable limits and to avoid situation when one RX queue can starve other queues, +each RX queue uses its own mempool. + +.. code-block:: c + + nb_mbuf = RTE_MAX(max_flow_num, 2UL * MAX_PKT_BURST) * RTE_LIBRTE_IP_FRAG_MAX_FRAGS; + nb_mbuf *= (port_conf.rxmode.max_rx_pkt_len + BUF_SIZE - 1) / BUF_SIZE; + nb_mbuf *= 2; /* ipv4 and ipv6 */ + nb_mbuf += RTE_TEST_RX_DESC_DEFAULT + RTE_TEST_TX_DESC_DEFAULT; + nb_mbuf = RTE_MAX(nb_mbuf, (uint32_t)NB_MBUF); + + snprintf(buf, sizeof(buf), "mbuf_pool_%u_%u", lcore, queue); + + if ((rxq->pool = rte_mempool_create(buf, nb_mbuf, MBUF_SIZE, 0, sizeof(struct rte_pktmbuf_pool_private), rte_pktmbuf_pool_init, NULL, + rte_pktmbuf_init, NULL, socket, MEMPOOL_F_SP_PUT | MEMPOOL_F_SC_GET)) == NULL) { + + RTE_LOG(ERR, IP_RSMBL, "mempool_create(%s) failed", buf); + return -1; + } + +Packet Reassembly and Forwarding +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +For each input packet, the packet forwarding operation is done by the l3fwd_simple_forward() function. +If the packet is an IPv4 or IPv6 fragment, then it calls rte_ipv4_reassemble_packet() for IPv4 packets, +or rte_ipv6_reassemble_packet() for IPv6 packets. +These functions either return a pointer to valid mbuf that contains reassembled packet, +or NULL (if the packet can't be reassembled for some reason). +Then l3fwd_simple_forward() continues with the code for the packet forwarding decision +(that is, the identification of the output interface for the packet) and +actual transmit of the packet. + +The rte_ipv4_reassemble_packet() or rte_ipv6_reassemble_packet() are responsible for: + +#. Searching the Fragment Table for entry with packet's + +#. If the entry is found, then check if that entry already timed-out. + If yes, then free all previously received fragments, + and remove information about them from the entry. + +#. If no entry with such key is found, then try to create a new one by one of two ways: + + #. Use as empty entry + + #. Delete a timed-out entry, free mbufs associated with it mbufs and store a new entry with specified key in it. + +#. Update the entry with new fragment information and check + if a packet can be reassembled (the packet's entry contains all fragments). + + #. If yes, then, reassemble the packet, mark table's entry as empty and return the reassembled mbuf to the caller. + + #. If no, then just return a NULL to the caller. + +If at any stage of packet processing a reassembly function encounters an error +(can't insert new entry into the Fragment table, or invalid/timed-out fragment), +then it will free all associated with the packet fragments, +mark the table entry as invalid and return NULL to the caller. + +Debug logging and Statistics Collection +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The RTE_LIBRTE_IP_FRAG_TBL_STAT controls statistics collection for the IP Fragment Table. +This macro is disabled by default. +To make ip_reassembly print the statistics to the standard output, +the user must send either an USR1, INT or TERM signal to the process. +For all of these signals, the ip_reassembly process prints Fragment table statistics for each RX queue, +plus the INT and TERM will cause process termination as usual. diff --git a/dpdk/doc/guides/sample_app_ug/ipsec_secgw.rst b/dpdk/doc/guides/sample_app_ug/ipsec_secgw.rst new file mode 100644 index 0000000..46696f2 --- /dev/null +++ b/dpdk/doc/guides/sample_app_ug/ipsec_secgw.rst @@ -0,0 +1,620 @@ +..

It also support +inline ipsec processing by the supported ethernet device during transmission. +These modes can be selected during the SA creation configuration. + +In case of complete protocol offload, the processing of headers(ESP and outer +IP header) is done by the hardware and the application does not need to +add/remove them during outbound/inbound processing. + +For inline offloaded outbound traffic, the application will not do the LPM +lookup for routing, as the port on which the packet has to be forwarded will be +part of the SA. Security parameters will be configured on that port only, and +sending the packet on other ports could result in unencrypted packets being +sent out. + +The Path for IPsec Inbound traffic is: + +* Read packets from the port. +* Classify packets between IPv4 and ESP. +* Perform Inbound SA lookup for ESP packets based on their SPI. +* Perform Verification/Decryption (Not needed in case of inline ipsec). +* Remove ESP and outer IP header (Not needed in case of protocol offload). +* Inbound SP check using ACL of decrypted packets and any other IPv4 packets. +* Routing. +* Write packet to port. + +The Path for the IPsec Outbound traffic is: + +* Read packets from the port. +* Perform Outbound SP check using ACL of all IPv4 traffic. +* Perform Outbound SA lookup for packets that need IPsec protection. +* Add ESP and outer IP header (Not needed in case protocol offload). +* Perform Encryption/Digest (Not needed in case of inline ipsec). +* Routing. +* Write packet to port. + + +Constraints +----------- + +* No IPv6 options headers. +* No AH mode. +* Supported algorithms: AES-CBC, AES-CTR, AES-GCM, HMAC-SHA1 and NULL. +* Each SA must be handle by a unique lcore (*1 RX queue per port*). +* No chained mbufs. + +Compiling the Application +------------------------- + +To compile the sample application see :doc:`compiling`. + +The application is located in the ``rpsec-secgw`` sub-directory. + +#. [Optional] Build the application for debugging: + This option adds some extra flags, disables compiler optimizations and + is verbose:: + + make DEBUG=1 + + +Running the Application +----------------------- + +The application has a number of command line options:: + + + ./build/ipsec-secgw [EAL options] -- + -p PORTMASK -P -u PORTMASK -j FRAMESIZE + --config (port,queue,lcore)[,(port,queue,lcore] + --single-sa SAIDX + -f CONFIG_FILE_PATH + +Where: + +* ``-p PORTMASK``: Hexadecimal bitmask of ports to configure. + +* ``-P``: *optional*. Sets all ports to promiscuous mode so that packets are + accepted regardless of the packet's Ethernet MAC destination address. + Without this option, only packets with the Ethernet MAC destination address + set to the Ethernet address of the port are accepted (default is enabled). + +* ``-u PORTMASK``: hexadecimal bitmask of unprotected ports + +* ``-j FRAMESIZE``: *optional*. Enables jumbo frames with the maximum size + specified as FRAMESIZE. If an invalid value is provided as FRAMESIZE + then the default value 9000 is used. + +* ``--config (port,queue,lcore)[,(port,queue,lcore)]``: determines which queues + from which ports are mapped to which cores. + +* ``--single-sa SAIDX``: use a single SA for outbound traffic, bypassing the SP + on both Inbound and Outbound. This option is meant for debugging/performance + purposes. + +* ``-f CONFIG_FILE_PATH``: the full path of text-based file containing all + configuration items for running the application (See Configuration file + syntax section below). ``-f CONFIG_FILE_PATH`` **must** be specified. + **ONLY** the UNIX format configuration file is accepted. + + +The mapping of lcores to port/queues is similar to other l3fwd applications. + +For example, given the following command line:: + + ./build/ipsec-secgw -l 20,21 -n 4 --socket-mem 0,2048 \ + --vdev "crypto_null" -- -p 0xf -P -u 0x3 \ + --config="(0,0,20),(1,0,20),(2,0,21),(3,0,21)" \ + -f /path/to/config_file \ + +where each options means: + +* The ``-l`` option enables cores 20 and 21. + +* The ``-n`` option sets memory 4 channels. + +* The ``--socket-mem`` to use 2GB on socket 1. + +* The ``--vdev "crypto_null"`` option creates virtual NULL cryptodev PMD. + +* The ``-p`` option enables ports (detected) 0, 1, 2 and 3. + +* The ``-P`` option enables promiscuous mode. + +* The ``-u`` option sets ports 1 and 2 as unprotected, leaving 2 and 3 as protected. + +* The ``--config`` option enables one queue per port with the following mapping: + + +----------+-----------+-----------+---------------------------------------+ + | **Port** | **Queue** | **lcore** | **Description** | + | | | | | + +----------+-----------+-----------+---------------------------------------+ + | 0 | 0 | 20 | Map queue 0 from port 0 to lcore 20. | + | | | | | + +----------+-----------+-----------+---------------------------------------+ + | 1 | 0 | 20 | Map queue 0 from port 1 to lcore 20. | + | | | | | + +----------+-----------+-----------+---------------------------------------+ + | 2 | 0 | 21 | Map queue 0 from port 2 to lcore 21. | + | | | | | + +----------+-----------+-----------+---------------------------------------+ + | 3 | 0 | 21 | Map queue 0 from port 3 to lcore 21. | + | | | | | + +----------+-----------+-----------+---------------------------------------+ + +* The ``-f /path/to/config_file`` option enables the application read and + parse the configuration file specified, and configures the application + with a given set of SP, SA and Routing entries accordingly. The syntax of + the configuration file will be explained below in more detail. Please + **note** the parser only accepts UNIX format text file. Other formats + such as DOS/MAC format will cause a parse error. + +Refer to the *DPDK Getting Started Guide* for general information on running +applications and the Environment Abstraction Layer (EAL) options. + +The application would do a best effort to "map" crypto devices to cores, with +hardware devices having priority. Basically, hardware devices if present would +be assigned to a core before software ones. +This means that if the application is using a single core and both hardware +and software crypto devices are detected, hardware devices will be used. + +A way to achieve the case where you want to force the use of virtual crypto +devices is to whitelist the Ethernet devices needed and therefore implicitly +blacklisting all hardware crypto devices. + +For example, something like the following command line: + +.. code-block:: console + + ./build/ipsec-secgw -l 20,21 -n 4 --socket-mem 0,2048 \ + -w 81:00.0 -w 81:00.1 -w 81:00.2 -w 81:00.3 \ + --vdev "crypto_aesni_mb" --vdev "crypto_null" \ + -- \ + -p 0xf -P -u 0x3 --config="(0,0,20),(1,0,20),(2,0,21),(3,0,21)" \ + -f sample.cfg + + +Configurations +-------------- + +The following sections provide the syntax of configurations to initialize +your SP, SA and Routing tables. +Configurations shall be specified in the configuration file to be passed to +the application. The file is then parsed by the application. The successful +parsing will result in the appropriate rules being applied to the tables +accordingly. + + +Configuration File Syntax +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +As mention in the overview, the Security Policies are ACL rules. +The application parsers the rules specified in the configuration file and +passes them to the ACL table, and replicates them per socket in use. + +Following are the configuration file syntax. + +General rule syntax +^^^^^^^^^^^^^^^^^^^ + +The parse treats one line in the configuration file as one configuration +item (unless the line concatenation symbol exists). Every configuration +item shall follow the syntax of either SP, SA, or Routing rules specified +below. + +The configuration parser supports the following special symbols: + + * Comment symbol **#**. Any character from this symbol to the end of + line is treated as comment and will not be parsed. + + * Line concatenation symbol **\\**.

+ +The reason for this is because indirect buffers are not supposed to hold any packet data and +therefore can be initialized with lower amount of reserved memory for each buffer. + +Hash Initialization +~~~~~~~~~~~~~~~~~~~ + +The hash object is created and loaded with the pre-configured entries read from a global array: + +.. code-block:: c + + static int + + init_mcast_hash(void) + { + uint32_t i; + mcast_hash_params.socket_id = rte_socket_id(); + + mcast_hash = rte_fbk_hash_create(&mcast_hash_params); + if (mcast_hash == NULL){ + return -1; + } + + for (i = 0; i < N_MCAST_GROUPS; i ++){ + if (rte_fbk_hash_add_key(mcast_hash, mcast_group_table[i].ip, mcast_group_table[i].port_mask) < 0) { + return -1; + } + } + return 0; + } + +Forwarding +~~~~~~~~~~ + +All forwarding is done inside the mcast_forward() function. +Firstly, the Ethernet* header is removed from the packet and the IPv4 address is extracted from the IPv4 header: + +.. code-block:: c + + /* Remove the Ethernet header from the input packet */ + + iphdr = (struct ipv4_hdr *)rte_pktmbuf_adj(m, sizeof(struct ether_hdr)); + RTE_ASSERT(iphdr != NULL); + dest_addr = rte_be_to_cpu_32(iphdr->dst_addr); + +Then, the packet is checked to see if it has a multicast destination address and +if the routing table has any ports assigned to the destination address: + +.. code-block:: c + + if (!IS_IPV4_MCAST(dest_addr) || + (hash = rte_fbk_hash_lookup(mcast_hash, dest_addr)) <= 0 || + (port_mask = hash & enabled_port_mask) == 0) { + rte_pktmbuf_free(m); + return; + } + +Then, the number of ports in the destination portmask is calculated with the help of the bitcnt() function: + +.. code-block:: c + + /* Get number of bits set. */ + + static inline uint32_t bitcnt(uint32_t v) + { + uint32_t n; + + for (n = 0; v != 0; v &= v - 1, n++) + ; + return n; + } + +This is done to determine which forwarding algorithm to use. +This is explained in more detail in the next section. + +Thereafter, a destination Ethernet address is constructed: + +.. code-block:: c + + /* construct destination Ethernet address */ + + dst_eth_addr = ETHER_ADDR_FOR_IPV4_MCAST(dest_addr); + +Since Ethernet addresses are also part of the multicast process, each outgoing packet carries the same destination Ethernet address. +The destination Ethernet address is constructed from the lower 23 bits of the multicast group OR-ed +with the Ethernet address 01:00:5e:00:00:00, as per RFC 1112: + +.. code-block:: c + + #define ETHER_ADDR_FOR_IPV4_MCAST(x) \ + (rte_cpu_to_be_64(0x01005e000000ULL | ((x) & 0x7fffff)) >> 16) + +Then, packets are dispatched to the destination ports according to the portmask associated with a multicast group: + +.. code-block:: c + + for (port = 0; use_clone != port_mask; port_mask >>= 1, port++) { + /* Prepare output packet and send it out. */ + + if ((port_mask & 1) != 0) { + if (likely ((mc = mcast_out_pkt(m, use_clone)) != NULL)) + mcast_send_pkt(mc, &dst_eth_addr.as_addr, qconf, port); + else if (use_clone == 0) + rte_pktmbuf_free(m); + } + } + +The actual packet transmission is done in the mcast_send_pkt() function: + +.. code-block:: c + + static inline void mcast_send_pkt(struct rte_mbuf *pkt, struct ether_addr *dest_addr, struct lcore_queue_conf *qconf, uint16_t port) + { + struct ether_hdr *ethdr;

+ ether_addr_copy(&ports_eth_addr[port], ðdr->s_addr); + ethdr->ether_type = rte_be_to_cpu_16(ETHER_TYPE_IPv4); + + /* Put new packet into the output queue */ + + len = qconf->tx_mbufs[port].len; + qconf->tx_mbufs[port].m_table[len] = pkt; + qconf->tx_mbufs[port].len = ++len; + + /* Transmit packets */ + + if (unlikely(MAX_PKT_BURST == len)) + send_burst(qconf, port); + } + +Buffer Cloning +~~~~~~~~~~~~~~ + +This is the most important part of the application since it demonstrates the use of zero- copy buffer cloning. +There are two approaches for creating the outgoing packet and although both are based on the data zero-copy idea, +there are some differences in the detail. + +The first approach creates a clone of the input packet, for example, +walk though all segments of the input packet and for each of segment, +create a new buffer and attach that new buffer to the segment +(refer to rte_pktmbuf_clone() in the rte_mbuf library for more details). +A new buffer is then allocated for the packet header and is prepended to the cloned buffer. + +The second approach does not make a clone, it just increments the reference counter for all input packet segment, +allocates a new buffer for the packet header and prepends it to the input packet. + +Basically, the first approach reuses only the input packet's data, but creates its own copy of packet's metadata. +The second approach reuses both input packet's data and metadata. + +The advantage of first approach is that each outgoing packet has its own copy of the metadata, +so we can safely modify the data pointer of the input packet. +That allows us to skip creation if the output packet is for the last destination port +and instead modify input packet's header in place. +For example, for N destination ports, we need to invoke mcast_out_pkt() (N-1) times. + +The advantage of the second approach is that there is less work to be done for each outgoing packet, +that is, the "clone" operation is skipped completely. +However, there is a price to pay. +The input packet's metadata must remain intact, so for N destination ports, +we need to invoke mcast_out_pkt() (N) times. + +Therefore, for a small number of outgoing ports (and segments in the input packet), +first approach is faster. +As the number of outgoing ports (and/or input segments) grows, the second approach becomes more preferable. + +Depending on the number of segments or the number of ports in the outgoing portmask, +either the first (with cloning) or the second (without cloning) approach is taken: + +.. code-block:: c + + use_clone = (port_num <= MCAST_CLONE_PORTS && m->pkt.nb_segs <= MCAST_CLONE_SEGS); + +It is the mcast_out_pkt() function that performs the packet duplication (either with or without actually cloning the buffers): + +.. code-block:: c + + static inline struct rte_mbuf *mcast_out_pkt(struct rte_mbuf *pkt, int use_clone) + { + struct rte_mbuf *hdr;

This: + +* Provides a faster mechanism to interface with the kernel net stack and eliminates system calls + +* Facilitates the DPDK using standard Linux* userspace net tools (tcpdump, ftp, and so on) + +* Eliminate the copy_to_user and copy_from_user operations on packets. + +The Kernel NIC Interface sample application is a simple example that demonstrates the use +of the DPDK to create a path for packets to go through the Linux* kernel. +This is done by creating one or more kernel net devices for each of the DPDK ports. +The application allows the use of standard Linux tools (ethtool, ifconfig, tcpdump) with the DPDK ports and +also the exchange of packets between the DPDK application and the Linux* kernel. + +Overview +-------- + +The Kernel NIC Interface sample application uses two threads in user space for each physical NIC port being used, +and allocates one or more KNI device for each physical NIC port with kernel module's support. +For a physical NIC port, one thread reads from the port and writes to KNI devices, +and another thread reads from KNI devices and writes the data unmodified to the physical NIC port. +It is recommended to configure one KNI device for each physical NIC port. +If configured with more than one KNI devices for a physical NIC port, +it is just for performance testing, or it can work together with VMDq support in future. + +The packet flow through the Kernel NIC Interface application is as shown in the following figure. + +.. _figure_kernel_nic: + +.. figure:: img/kernel_nic.* + + Kernel NIC Application Packet Flow + +Compiling the Application +------------------------- + +To compile the sample application see :doc:`compiling`. + +The application is located in the ``kni`` sub-directory. + +.. note:: + + This application is intended as a linuxapp only. + +Loading the Kernel Module +------------------------- + +Loading the KNI kernel module without any parameter is the typical way a DPDK application +gets packets into and out of the kernel net stack. +This way, only one kernel thread is created for all KNI devices for packet receiving in kernel side: + +.. code-block:: console + + #insmod rte_kni.ko + +Pinning the kernel thread to a specific core can be done using a taskset command such as following: + +.. code-block:: console + + #taskset -p 100000 `pgrep --fl kni_thread | awk '{print $1}'` + +This command line tries to pin the specific kni_thread on the 20th lcore (lcore numbering starts at 0), +which means it needs to check if that lcore is available on the board. +This command must be sent after the application has been launched, as insmod does not start the kni thread. + +For optimum performance, +the lcore in the mask must be selected to be on the same socket as the lcores used in the KNI application. + +To provide flexibility of performance, the kernel module of the KNI, +located in the kmod sub-directory of the DPDK target directory, +can be loaded with parameter of kthread_mode as follows: + +* #insmod rte_kni.ko kthread_mode=single + + This mode will create only one kernel thread for all KNI devices for packet receiving in kernel side. + By default, it is in this single kernel thread mode. + It can set core affinity for this kernel thread by using Linux command taskset. + +* #insmod rte_kni.ko kthread_mode =multiple + + This mode will create a kernel thread for each KNI device for packet receiving in kernel side. + The core affinity of each kernel thread is set when creating the KNI device. + The lcore ID for each kernel thread is provided in the command line of launching the application. + Multiple kernel thread mode can provide scalable higher performance. + +To measure the throughput in a loopback mode, the kernel module of the KNI, +located in the kmod sub-directory of the DPDK target directory, +can be loaded with parameters as follows: + +* #insmod rte_kni.ko lo_mode=lo_mode_fifo + + This loopback mode will involve ring enqueue/dequeue operations in kernel space. + +* #insmod rte_kni.ko lo_mode=lo_mode_fifo_skb + + This loopback mode will involve ring enqueue/dequeue operations and sk buffer copies in kernel space. + +Running the Application +----------------------- + +The application requires a number of command line options: + +.. code-block:: console + + kni [EAL options] -- -P -p PORTMASK --config="(port,lcore_rx,lcore_tx[,lcore_kthread,...])[,port,lcore_rx,lcore_tx[,lcore_kthread,...]]" + +Where: + +* -P: Set all ports to promiscuous mode so that packets are accepted regardless of the packet's Ethernet MAC destination address. + Without this option, only packets with the Ethernet MAC destination address set to the Ethernet address of the port are accepted. + +* -p PORTMASK: Hexadecimal bitmask of ports to configure. + +* --config="(port,lcore_rx, lcore_tx[,lcore_kthread, ...]) [, port,lcore_rx, lcore_tx[,lcore_kthread, ...]]": + Determines which lcores of RX, TX, kernel thread are mapped to which ports. + +Refer to *DPDK Getting Started Guide* for general information on running applications and the Environment Abstraction Layer (EAL) options. + +The -c coremask or -l corelist parameter of the EAL options should include the lcores indicated by the lcore_rx and lcore_tx, +but does not need to include lcores indicated by lcore_kthread as they are used to pin the kernel thread on. +The -p PORTMASK parameter should include the ports indicated by the port in --config, neither more nor less. + +The lcore_kthread in --config can be configured none, one or more lcore IDs. +In multiple kernel thread mode, if configured none, a KNI device will be allocated for each port, +while no specific lcore affinity will be set for its kernel thread. +If configured one or more lcore IDs, one or more KNI devices will be allocated for each port, +while specific lcore affinity will be set for its kernel thread. +In single kernel thread mode, if configured none, a KNI device will be allocated for each port. +If configured one or more lcore IDs, +one or more KNI devices will be allocated for each port while +no lcore affinity will be set as there is only one kernel thread for all KNI devices. + +For example, to run the application with two ports served by six lcores, one lcore of RX, one lcore of TX, +and one lcore of kernel thread for each port: + +..

It has been extended to make use of CAT via extended +command line options and linking against the libpqos library. + +It is intended as a demonstration of the basic components of a DPDK forwarding +application and use of the libpqos library to program CAT. +For more detailed implementations see the L2 and L3 forwarding +sample applications. + +CAT and Code Data Prioritization (CDP) features allow management of the CPU's +last level cache. CAT introduces classes of service (COS) that are essentially +bitmasks. In current CAT implementations, a bit in a COS bitmask corresponds to +one cache way in last level cache. +A CPU core is always assigned to one of the CAT classes. +By programming CPU core assignment and COS bitmasks, applications can be given +exclusive, shared, or mixed access to the CPU's last level cache. +CDP extends CAT so that there are two bitmasks per COS, +one for data and one for code. +The number of classes and number of valid bits in a COS bitmask is CPU model +specific and COS bitmasks need to be contiguous. Sample code calls this bitmask +``cbm`` or capacity bitmask. +By default, after reset, all CPU cores are assigned to COS 0 and all classes +are programmed to allow fill into all cache ways. +CDP is off by default. + +For more information about CAT please see: + +* https://github.com/01org/intel-cmt-cat + +White paper demonstrating example use case: + +* `Increasing Platform Determinism with Platform Quality of Service for the Data Plane Development Kit `_ + +Compiling the Application +------------------------- +.. note:: + + Requires ``libpqos`` from Intel's + `intel-cmt-cat software package `_ + hosted on GitHub repository.

Statistics from this part of code is considered as the headroom available for additional processing. + +Receive, Process and Transmit Packets +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The main task of l2fwd_fwd_job() function is to read ingress packets from the RX queue of particular port and forward it. +This is done using the following code: + +.. code-block:: c + + total_nb_rx = rte_eth_rx_burst((uint8_t) portid, 0, pkts_burst, + MAX_PKT_BURST); + + for (j = 0; j < total_nb_rx; j++) { + m = pkts_burst[j]; + rte_prefetch0(rte_pktmbuf_mtod(m, void *)); + l2fwd_simple_forward(m, portid); + } + +Packets are read in a burst of size MAX_PKT_BURST. +Then, each mbuf in the table is processed by the l2fwd_simple_forward() function. +The processing is very simple: process the TX port from the RX port, then replace the source and destination MAC addresses. + +The rte_eth_rx_burst() function writes the mbuf pointers in a local table and returns the number of available mbufs in the table. + +After first read second try is issued. + +.. code-block:: c + + if (total_nb_rx == MAX_PKT_BURST) { + const uint16_t nb_rx = rte_eth_rx_burst((uint8_t) portid, 0, pkts_burst, + MAX_PKT_BURST); + + total_nb_rx += nb_rx; + for (j = 0; j < nb_rx; j++) { + m = pkts_burst[j]; + rte_prefetch0(rte_pktmbuf_mtod(m, void *)); + l2fwd_simple_forward(m, portid); + } + } + +This second read is important to give job stats library a feedback how many packets was processed. + +.. code-block:: c + + /* Adjust period time in which we are running here. */ + if (rte_jobstats_finish(job, total_nb_rx) != 0) { + rte_timer_reset(&qconf->rx_timers[port_idx], job->period, PERIODICAL, + lcore_id, l2fwd_fwd_job, arg); + } + +To maximize performance exactly MAX_PKT_BURST is expected (the target value) to be read for each l2fwd_fwd_job() call. +If total_nb_rx is smaller than target value job->period will be increased. If it is greater the period will be decreased. + +.. note:: + + In the following code, one line for getting the output port requires some explanation. + +During the initialization process, a static array of destination ports (l2fwd_dst_ports[]) is filled such that for each source port, +a destination port is assigned that is either the next or previous enabled port from the portmask. +Naturally, the number of ports in the portmask must be even, otherwise, the application exits. + +.. code-block:: c + + static void + l2fwd_simple_forward(struct rte_mbuf *m, unsigned portid) + { + struct ether_hdr *eth; + void *tmp; + unsigned dst_port; + + dst_port = l2fwd_dst_ports[portid]; + + eth = rte_pktmbuf_mtod(m, struct ether_hdr *); + + /* 02:00:00:00:00:xx */ + + tmp = ð->d_addr.addr_bytes[0]; + + *((uint64_t *)tmp) = 0x000000000002 + ((uint64_t) dst_port << 40); + + /* src addr */ + + ether_addr_copy(&l2fwd_ports_eth_addr[dst_port], ð->s_addr); + + l2fwd_send_packet(m, (uint8_t) dst_port); + } + +Then, the packet is sent using the l2fwd_send_packet (m, dst_port) function. +For this test application, the processing is exactly the same for all packets arriving on the same RX port. +Therefore, it would have been possible to call the l2fwd_send_burst() function directly from the main loop +to send all the received packets on the same TX port, +using the burst-oriented send function, which is more efficient. + +However, in real-life applications (such as, L3 routing), +packet N is not necessarily forwarded on the same port as packet N-1. +The application is implemented to illustrate that, so the same approach can be reused in a more complex application. + +The l2fwd_send_packet() function stores the packet in a per-lcore and per-txport table. +If the table is full, the whole packets table is transmitted using the l2fwd_send_burst() function: + +.. code-block:: c + + /* Send the packet on an output interface */ + + static int + l2fwd_send_packet(struct rte_mbuf *m, uint16_t port) + { + unsigned lcore_id, len; + struct lcore_queue_conf *qconf; + + lcore_id = rte_lcore_id(); + qconf = &lcore_queue_conf[lcore_id]; + len = qconf->tx_mbufs[port].len; + qconf->tx_mbufs[port].m_table[len] = m; + len++; + + /* enough pkts to be sent */ + + if (unlikely(len == MAX_PKT_BURST)) { + l2fwd_send_burst(qconf, MAX_PKT_BURST, port); + len = 0; + } + + qconf->tx_mbufs[port].len = len; return 0; + } + +To ensure that no packets remain in the tables, the flush job exists.

in real and virtualized environments, +performs L2 forwarding for each packet that is received on an RX_PORT. +The destination port is the adjacent port from the enabled portmask, that is, +if the first four ports are enabled (portmask 0xf), +ports 1 and 2 forward into each other, and ports 3 and 4 forward into each other. +Also, if MAC addresses updating is enabled, the MAC addresses are affected as follows: + +* The source MAC address is replaced by the TX_PORT MAC address + +* The destination MAC address is replaced by 02:00:00:00:00:TX_PORT_ID + +This application can be used to

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +This application can use the virtual function available in the system and +therefore can be used in a virtual machine without passing through +the whole Network Device into a guest machine in a virtualized scenario. +The virtual functions can be enabled in the host machine or the hypervisor with the respective physical function driver. + +For example, in a Linux* host machine, it is possible to enable a virtual function using the following command: + +.. code-block:: console + + modprobe ixgbe max_vfs=2,2 + +This command enables two Virtual Functions on each of Physical Function of the NIC, +with two physical ports in the PCI configuration space. +It is important to note that enabled Virtual Function 0 and 2 would belong to Physical Function 0 +and Virtual Function 1 and 3 would belong to Physical Function 1, +in this case enabling a total of four Virtual Functions. + +Compiling the Application +------------------------- + +To compile the sample application see :doc:`compiling`. + +The application is located in the ``l2fwd`` sub-directory. + +Running the Application +----------------------- + +The application requires a number of command line options: + +.. code-block:: console + + ./build/l2fwd [EAL options] -- -p PORTMASK [-q NQ] --[no-]mac-updating + +where, + +* p PORTMASK: A hexadecimal bitmask of the ports to configure + +* q NQ: A number of queues (=ports) per lcore (default is 1) + +* --[no-]mac-updating: Enable or disable MAC addresses updating (enabled by default). + +To run the application in linuxapp environment with 4 lcores, 16 ports and 8 RX queues per lcore and MAC address +updating enabled, issue the command: + +.. code-block:: console + + $ ./build/l2fwd -l 0-3 -n 4 -- -q 8 -p ffff + +Refer to the *DPDK Getting Started Guide* for general information on running applications +and the Environment Abstraction Layer (EAL) options. + +Explanation +----------- + +The following sections provide some explanation of the code. + +.. _l2_fwd_app_cmd_arguments: + +Command Line Arguments +~~~~~~~~~~~~~~~~~~~~~~ + +The L2 Forwarding sample application takes specific parameters, +in addition to Environment Abstraction Layer (EAL) arguments. +The preferred way to parse parameters is to use the getopt() function, +since it is part of a well-defined and portable library. + +The parsing of arguments is done in the l2fwd_parse_args() function. +The method of argument parsing is not described here. +Refer to the *glibc getopt(3)* man page for details. + +EAL arguments are parsed first, then application-specific arguments. +This is done at the beginning of the main() function: + +.. code-block:: c + + /* init EAL */ + + ret = rte_eal_init(argc, argv); + if (ret < 0) + rte_exit(EXIT_FAILURE, "Invalid EAL arguments\n"); + + argc -= ret; + argv += ret; + + /* parse application arguments (after the EAL ones) */ + + ret = l2fwd_parse_args(argc, argv); + if (ret < 0) + rte_exit(EXIT_FAILURE, "Invalid L2FWD arguments\n"); + +.. _l2_fwd_app_mbuf_init: + +Mbuf Pool Initialization +~~~~~~~~~~~~~~~~~~~~~~~~ + +Once the arguments are parsed, the mbuf pool is created. +The mbuf pool contains a set of mbuf objects that will be used by the driver +and the application to store network packet data: + +.. code-block:: c + + /* create the mbuf pool */ + + l2fwd_pktmbuf_pool = rte_pktmbuf_pool_create("mbuf_pool", NB_MBUF, + MEMPOOL_CACHE_SIZE, 0, RTE_MBUF_DEFAULT_BUF_SIZE, + rte_socket_id()); + + if (l2fwd_pktmbuf_pool == NULL) + rte_panic("Cannot init mbuf pool\n"); + +The rte_mempool is a generic structure used to handle pools of objects. +In this case, it is necessary to create a pool that will be used by the driver. +The number of allocated pkt mbufs is NB_MBUF, with a data room size of +RTE_MBUF_DEFAULT_BUF_SIZE each. +A per-lcore cache of 32 mbufs is kept. +The memory is allocated in NUMA socket 0, +but it is possible to extend this code to allocate one mbuf pool per socket. + +The rte_pktmbuf_pool_create() function uses the default mbuf pool and mbuf +initializers, respectively rte_pktmbuf_pool_init() and rte_pktmbuf_init(). +An advanced application may want to use the mempool API to create the +mbuf pool with more control. + +.. _l2_fwd_app_dvr_init: + +Driver Initialization +~~~~~~~~~~~~~~~~~~~~~ + +The main part of the code in the main() function relates to the initialization of the driver. +To fully understand this code, it is recommended to study the chapters that related to the Poll Mode Driver +in the *DPDK Programmer's Guide* - Rel 1.4 EAR and the *DPDK API Reference*. + +.. code-block:: c + + if (rte_pci_probe() < 0) + rte_exit(EXIT_FAILURE, "Cannot probe PCI\n"); + + /* reset l2fwd_dst_ports */ + + for (portid = 0; portid < RTE_MAX_ETHPORTS; portid++) + l2fwd_dst_ports[portid] = 0; + + last_port = 0; + + /* + * Each logical core is assigned a dedicated TX queue on each port. + */ + + RTE_ETH_FOREACH_DEV(portid) { + /* skip ports that are not enabled */ + + if ((l2fwd_enabled_port_mask & (1 << portid)) == 0) + continue; + + if (nb_ports_in_mask % 2) { + l2fwd_dst_ports[portid] = last_port; + l2fwd_dst_ports[last_port] = portid; + } + else + last_port = portid; + + nb_ports_in_mask++; + + rte_eth_dev_info_get((uint8_t) portid, &dev_info); + } + +Observe that: + +* rte_igb_pmd_init_all() simultaneously registers the driver as a PCI driver and as an Ethernet* Poll Mode Driver. + +* rte_pci_probe() parses the devices on the PCI bus and initializes recognized devices. + +The next step is to configure the RX and TX queues. +For each port, there is only one RX queue (only one lcore is able to poll a given port). +The number of TX queues depends on the number of available lcores. +The rte_eth_dev_configure() function is used to configure the number of queues for a port: + +.. code-block:: c + + ret = rte_eth_dev_configure((uint8_t)portid, 1, 1, &port_conf); + if (ret < 0) + rte_exit(EXIT_FAILURE, "Cannot configure device: " + "err=%d, port=%u\n", + ret, portid); + +The global configuration is stored in a static structure: + +.. code-block:: c + + static const struct rte_eth_conf port_conf = { + .rxmode = { + .split_hdr_size = 0, + .header_split = 0, /**< Header Split disabled */ + .hw_ip_checksum = 0, /**< IP checksum offload disabled */ + .hw_vlan_filter = 0, /**< VLAN filtering disabled */ + .jumbo_frame = 0, /**< Jumbo Frame Support disabled */ + .hw_strip_crc= 0, /**< CRC stripped by hardware */ + }, + + .txmode = { + .mq_mode = ETH_DCB_NONE + }, + }; + +.. _l2_fwd_app_rx_init: + +RX Queue Initialization +~~~~~~~~~~~~~~~~~~~~~~~ + +The application uses one lcore to poll one or several ports, depending on the -q option, +which specifies the number of queues per lcore. + +For example, if the user specifies -q 4, the application is able to poll four ports with one lcore. +If there are 16 ports on the target (and if the portmask argument is -p ffff ), +the application will need four lcores to poll all the ports. + +.. code-block:: c + + ret = rte_eth_rx_queue_setup((uint8_t) portid, 0, nb_rxd, SOCKET0, &rx_conf, l2fwd_pktmbuf_pool); + if (ret < 0) + + rte_exit(EXIT_FAILURE, "rte_eth_rx_queue_setup: " + "err=%d, port=%u\n", + ret, portid); + +The list of queues that must be polled for a given lcore is stored in a private structure called struct lcore_queue_conf. + +.. code-block:: c + + struct lcore_queue_conf { + unsigned n_rx_port; + unsigned rx_port_list[MAX_RX_QUEUE_PER_LCORE]; + struct mbuf_table tx_mbufs[L2FWD_MAX_PORTS]; + } rte_cache_aligned; + + struct lcore_queue_conf lcore_queue_conf[RTE_MAX_LCORE]; + +The values n_rx_port and rx_port_list[] are used in the main packet processing loop +(see :ref:`l2_fwd_app_rx_tx_packets`). + +The global configuration for the RX queues is stored in a static structure: + +.. code-block:: c + + static const struct rte_eth_rxconf rx_conf = { + .rx_thresh = { + .pthresh = RX_PTHRESH, + .hthresh = RX_HTHRESH, + .wthresh = RX_WTHRESH, + }, + }; + +.. _l2_fwd_app_tx_init: + +TX Queue Initialization +~~~~~~~~~~~~~~~~~~~~~~~ + +Each lcore should be able to transmit on any port. For every port, a single TX queue is initialized. + +.. code-block:: c + + /* init one TX queue on each port */ + + fflush(stdout); + + ret = rte_eth_tx_queue_setup((uint8_t) portid, 0, nb_txd, rte_eth_dev_socket_id(portid), &tx_conf); + if (ret < 0) + rte_exit(EXIT_FAILURE, "rte_eth_tx_queue_setup:err=%d, port=%u\n", ret, (unsigned) portid); + +The global configuration for TX queues is stored in a static structure: + +.. code-block:: c + + static const struct rte_eth_txconf tx_conf = { + .tx_thresh = { + .pthresh = TX_PTHRESH, + .hthresh = TX_HTHRESH, + .wthresh = TX_WTHRESH, + }, + .tx_free_thresh = RTE_TEST_TX_DESC_DEFAULT + 1, /* disable feature */ + }; + +.. _l2_fwd_app_rx_tx_packets: + +Receive, Process and Transmit Packets +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +In the l2fwd_main_loop() function, the main task is to read ingress packets from the RX queues. +This is done using the following code: + +.. code-block:: c + + /* + * Read packet from RX queues + */ + + for (i = 0; i < qconf->n_rx_port; i++) { + portid = qconf->rx_port_list[i]; + nb_rx = rte_eth_rx_burst((uint8_t) portid, 0, pkts_burst, MAX_PKT_BURST); + + for (j = 0; j < nb_rx; j++) { + m = pkts_burst[j]; + rte_prefetch0[rte_pktmbuf_mtod(m, void *)); l2fwd_simple_forward(m, portid); + } + } + +Packets are read in a burst of size MAX_PKT_BURST. +The rte_eth_rx_burst() function writes the mbuf pointers in a local table and returns the number of available mbufs in the table. + +Then, each mbuf in the table is processed by the l2fwd_simple_forward() function. +The processing is very simple: process the TX port from the RX port, then replace the source and destination MAC addresses if MAC +addresses updating is enabled. + +.. note:: + + In the following code, one line for getting the output port requires some explanation. + +During the initialization process, a static array of destination ports (l2fwd_dst_ports[]) is filled such that for each source port, +a destination port is assigned that is either the next or previous enabled port from the portmask. +Naturally, the number of ports in the portmask must be even, otherwise, the application exits. + +.. code-block:: c + + static void + l2fwd_simple_forward(struct rte_mbuf *m, unsigned portid) + { + struct ether_hdr *eth;

When the selected lookup method is hash-based, +a hash object is used to emulate the flow classification stage. +The hash object is used in correlation with a flow table to map each input packet to its flow at runtime. + +The hash lookup key is represented by a DiffServ 5-tuple composed of the following fields read from the input packet: +Source IP Address, Destination IP Address, Protocol, Source Port and Destination Port. +The ID of the output interface for the input packet is read from the identified flow table entry. +The set of flows used by the application is statically configured and loaded into the hash at initialization time. +When the selected lookup method is LPM based, an LPM object is used to emulate the forwarding stage for IPv4 packets. +The LPM object is used as the routing table to identify the next hop for each input packet at runtime. + +The LPM lookup key is represented by the Destination IP Address field read from the input packet. +The ID of the output interface for the input packet is the next hop returned by the LPM lookup. +The set of LPM rules used by the application is statically configured and loaded into the LPM object at initialization time. + +In the sample application, hash-based forwarding supports IPv4 and IPv6.

SPDX-License-Identifier: BSD-3-Clause + Copyright(c) 2010-2014 Intel Corporation. + +L3 Forwarding with Access Control Sample Application +==================================================== + +The L3 Forwarding with Access Control application is a simple example of packet processing using the DPDK. +The application performs a security check on received packets. +Packets that are in the Access Control List (ACL), which is loaded during initialization, are dropped. +Others are forwarded to the correct port. + +Overview +-------- + +The application demonstrates the use of the ACL library in the DPDK to implement access control +and packet L3 forwarding. +The application loads two types of rules at initialization: + +* Route information rules, which are used for L3 forwarding + +* Access Control List (ACL) rules that blacklist (or block) packets with a specific characteristic + +When packets are received from a port, +the application extracts the necessary information from the TCP/IP header of the received packet and +performs a lookup in the rule database to figure out whether the packets should be dropped (in the ACL range) +or forwarded to desired ports. +The initialization and run-time paths are similar to those of the :doc:`l3_forward`. +However, there are significant differences in the two applications. +For example, the original L3 forwarding application uses either LPM or +an exact match algorithm to perform forwarding port lookup, +while this application uses the ACL library to perform both ACL and route entry lookup. +The following sections provide more detail. + +Classification for both IPv4 and IPv6 packets is supported in this application. +The application also assumes that all the packets it processes are TCP/UDP packets and +always extracts source/destination port information from the packets. + +Tuple Packet Syntax +~~~~~~~~~~~~~~~~~~~ + +The application implements packet classification for the IPv4/IPv6 5-tuple syntax specifically. +The 5-tuple syntax consist of a source IP address, a destination IP address, +a source port, a destination port and a protocol identifier. +The fields in the 5-tuple syntax have the following formats: + +* **Source IP address and destination IP address** + : Each is either a 32-bit field (for IPv4), or a set of 4 32-bit fields (for IPv6) represented by a value and a mask length. + For example, an IPv4 range of 192.168.1.0 to 192.168.1.255 could be represented by a value = [192, 168, 1, 0] and a mask length = 24. + +* **Source port and destination port** + : Each is a 16-bit field, represented by a lower start and a higher end. + For example, a range of ports 0 to 8192 could be represented by lower = 0 and higher = 8192. + +* **Protocol identifier** + : An 8-bit field, represented by a value and a mask, that covers a range of values. + To verify that a value is in the range, use the following expression: "(VAL & mask) == value" + +The trick in how to represent a range with a mask and value is as follows. +A range can be enumerated in binary numbers with some bits that are never changed and some bits that are dynamically changed. +Set those bits that dynamically changed in mask and value with 0. +Set those bits that never changed in the mask with 1, in value with number expected. +For example, a range of 6 to 7 is enumerated as 0b110 and 0b111. +Bit 1-7 are bits never changed and bit 0 is the bit dynamically changed. +Therefore, set bit 0 in mask and value with 0, set bits 1-7 in mask with 1, and bits 1-7 in value with number 0b11. +So, mask is 0xfe, value is 0x6. + +.. note:: + + The library assumes that each field in the rule is in LSB or Little Endian order when creating the database. + It internally converts them to MSB or Big Endian order. + When performing a lookup, the library assumes the input is in MSB or Big Endian order. + +Access Rule Syntax +~~~~~~~~~~~~~~~~~~ + +In this sample application, each rule is a combination of the following: + +* 5-tuple field: This field has a format described in Section. + +* priority field: A weight to measure the priority of the rules. + The rule with the higher priority will ALWAYS be returned if the specific input has multiple matches in the rule database. + Rules with lower priority will NEVER be returned in any cases. + +* userdata field: A user-defined field that could be any value. + It can be the forwarding port number if the rule is a route table entry or it can be a pointer to a mapping address + if the rule is used for address mapping in the NAT application. + The key point is that it is a useful reserved field for user convenience. + +ACL and Route Rules +~~~~~~~~~~~~~~~~~~~ + +The application needs to acquire ACL and route rules before it runs. +Route rules are mandatory, while ACL rules are optional. +To simplify the complexity of the priority field for each rule, all ACL and route entries are assumed to be in the same file. +To read data from the specified file successfully, the application assumes the following: + +* Each rule occupies a single line. + +* Only the following four rule line types are valid in this application: + +* ACL rule line, which starts with a leading character '@' + +* Route rule line, which starts with a leading character 'R' + +* Comment line, which starts with a leading character '#' + +* Empty line, which consists of a space, form-feed ('\f'), newline ('\n'), + carriage return ('\r'), horizontal tab ('\t'), or vertical tab ('\v'). + +Other lines types are considered invalid. + +* Rules are organized in descending order of priority, + which means rules at the head of the file always have a higher priority than those further down in the file. + +* A typical IPv4 ACL rule line should have a format as shown below: + + +.. _figure_ipv4_acl_rule: + +.. figure:: img/ipv4_acl_rule.* + + A typical IPv4 ACL rule + + +IPv4 addresses are specified in CIDR format as specified in RFC 4632. +They consist of the dot notation for the address and a prefix length separated by '/'. +For example, 192.168.0.34/32, where the address is 192.168.0.34 and the prefix length is 32. + +Ports are specified as a range of 16-bit numbers in the format MIN:MAX, +where MIN and MAX are the inclusive minimum and maximum values of the range. +The range 0:65535 represents all possible ports in a range. +When MIN and MAX are the same value, a single port is represented, for example, 20:20. + +The protocol identifier is an 8-bit value and a mask separated by '/'. +For example: 6/0xfe matches protocol values 6 and 7. + +* Route rules start with a leading character 'R' and have the same format as ACL rules except an extra field at the tail + that indicates the forwarding port number. + +Rules File Example +~~~~~~~~~~~~~~~~~~ + +.. _figure_example_rules: + +.. figure:: img/example_rules.* + + Rules example + + +Each rule is explained as follows: + +* Rule 1 (the first line) tells the application to drop those packets with source IP address = [1.2.3.*], + destination IP address = [192.168.0.36], protocol = [6]/[7] + +* Rule 2 (the second line) is similar to Rule 1, except the source IP address is ignored. + It tells the application to forward packets with destination IP address = [192.168.0.36], + protocol = [6]/[7], destined to port 1. + +* Rule 3 (the third line) tells the application to forward all packets to port 0. + This is something like a default route entry. + +As described earlier, the application assume rules are listed in descending order of priority, +therefore Rule 1 has the highest priority, then Rule 2, and finally, +Rule 3 has the lowest priority. + +Consider the arrival of the following three packets: + +* Packet 1 has source IP address = [1.2.3.4], destination IP address = [192.168.0.36], and protocol = [6] + +* Packet 2 has source IP address = [1.2.4.4], destination IP address = [192.168.0.36], and protocol = [6] + +* Packet 3 has source IP address = [1.2.3.4], destination IP address = [192.168.0.36], and protocol = [8] + +Observe that: + +* Packet 1 matches all of the rules + +* Packet 2 matches Rule 2 and Rule 3 + +* Packet 3 only matches Rule 3 + +For priority reasons, Packet 1 matches Rule 1 and is dropped. +Packet 2 matches Rule 2 and is forwarded to port 1. +Packet 3 matches Rule 3 and is forwarded to port 0. + +For more details on the rule file format, +please refer to rule_ipv4.db and rule_ipv6.db files (inside /examples/l3fwd-acl/). + +Application Phases +~~~~~~~~~~~~~~~~~~ + +Once the application starts, it transitions through three phases: + +* **Initialization Phase** + - Perform the following tasks: + +* Parse command parameters. Check the validity of rule file(s) name(s), number of logical cores, receive and transmit queues. + Bind ports, queues and logical cores. Check ACL search options, and so on. + +* Call Environmental Abstraction Layer (EAL) and Poll Mode Driver (PMD) functions to initialize the environment and detect possible NICs. + The EAL creates several threads and sets affinity to a specific hardware thread CPU based on the configuration specified + by the command line arguments. + +* Read the rule files and format the rules into the representation that the ACL library can recognize. + Call the ACL library function to add the rules into the database and compile them as a trie of pattern sets. + Note that application maintains a separate AC contexts for IPv4 and IPv6 rules. + +* **Runtime Phase** + - Process the incoming packets from a port. Packets are processed in three steps: + + * Retrieval: Gets a packet from the receive queue. Each logical core may process several queues for different ports. + This depends on the configuration specified by command line arguments. + + * Lookup: Checks that the packet type is supported (IPv4/IPv6) and performs a 5-tuple lookup over corresponding AC context. + If an ACL rule is matched, the packets will be dropped and return back to step 1. + If a route rule is matched, it indicates the packet is not in the ACL list and should be forwarded. + If there is no matches for the packet, then the packet is dropped. + + * Forwarding: Forwards the packet to the corresponding port. + +* **Final Phase** -

Each C-state has a target residency. +It is essential that when entering into a C-state, the core remains in this C-state for at least as long as the target residency in order +to fully realize the benefits of entering the C-state. +CPUIdle is the infrastructure provide by the Linux kernel to control the processor C-state capability. +Unlike CPUFreq, CPUIdle does not provide a mechanism that allows the application to change C-state. +It actually has its own heuristic algorithms in kernel space to select target C-state to enter by executing privileged instructions like HLT and MWAIT, +based on the speculative sleep duration of the core. +In this application, we introduce a heuristic algorithm that allows packet processing cores to sleep for a short period +if there is no Rx packet received on recent polls. +In this way, CPUIdle automatically forces the corresponding cores to enter deeper C-states +instead of always running to the C0 state waiting for packets. + +.. note:: + + To fully demonstrate the power saving capability of using C-states, + it is recommended to enable deeper C3 and C6 states in the BIOS during system boot up. + +Compiling the Application +------------------------- + +To compile the sample application see :doc:`compiling`. + +The application is located in the ``l3fwd-power`` sub-directory. + +Running the Application +----------------------- + +The application has a number of command line options: + +.. code-block:: console + + ./build/l3fwd_power [EAL options] -- -p PORTMASK [-P] --config(port,queue,lcore)[,(port,queue,lcore)] [--enable-jumbo [--max-pkt-len PKTLEN]] [--no-numa] + +where, + +* -p PORTMASK: Hexadecimal bitmask of ports to configure + +* -P: Sets all ports to promiscuous mode so that packets are accepted regardless of the packet's Ethernet MAC destination address. + Without this option, only packets with the Ethernet MAC destination address set to the Ethernet address of the port are accepted. + +* --config (port,queue,lcore)[,(port,queue,lcore)]: determines which queues from which ports are mapped to which cores. + +* --enable-jumbo: optional, enables jumbo frames + +* --max-pkt-len: optional, maximum packet length in decimal (64-9600) + +* --no-numa: optional, disables numa awareness + +See :doc:`l3_forward` for details. +The L3fwd-power example reuses the L3fwd command line options. + +Explanation +----------- + +The following sections provide some explanation of the sample application code. +As mentioned in the overview section, +the initialization and run-time paths are identical to those of the L3 forwarding application. +The following sections describe aspects that are specific to the L3 Forwarding with Power Management sample application. + +Power Library Initialization +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The Power library is initialized in the main routine. +It changes the P-state governor to userspace for specific cores that are under control. +The Timer library is also initialized and several timers are created later on, +responsible for checking if it needs to scale down frequency at run time by checking CPU utilization statistics. + +.. note:: + + Only the power management related initialization is shown. + +.. code-block:: c + + int main(int argc, char **argv) + { + struct lcore_conf *qconf;

"LSC interrupt" : "unknown event"); + + rte_eth_link_get_nowait(port_id, &link); + + if (link.link_status) { + printf("Port %d Link Up - speed %u Mbps - %s\n\n", port_id, (unsigned)link.link_speed, + (link.link_duplex == ETH_LINK_FULL_DUPLEX) ? ("full-duplex") : ("half-duplex")); + } else + printf("Port %d Link Down\n\n", port_id); + } + +This function is called when a link status interrupt is present for the right port. +The port_id indicates which port the interrupt applies to. +The type parameter identifies the interrupt event type, +which currently can be RTE_ETH_EVENT_INTR_LSC only, but other types can be added in the future. +The param parameter is the address of the parameter for the callback. +This function should be implemented with care since it will be called in the interrupt host thread, +which is different from the main thread of its caller. + +The application registers the lsi_event_callback and a NULL parameter to the link status interrupt event on each port: + +.. code-block:: c + + rte_eth_dev_callback_register((uint8_t)portid, RTE_ETH_EVENT_INTR_LSC, lsi_event_callback, NULL); + +This registration can be done only after calling the rte_eth_dev_configure() function and before calling any other function. +If lsc is initialized with 0, the callback is never called since no interrupt event would ever be present. + +RX Queue Initialization +~~~~~~~~~~~~~~~~~~~~~~~ + +The application uses one lcore to poll one or several ports, depending on the -q option, +which specifies the number of queues per lcore. + +For example, if the user specifies -q 4, the application is able to poll four ports with one lcore. +If there are 16 ports on the target (and if the portmask argument is -p ffff), +the application will need four lcores to poll all the ports. + +.. code-block:: c + + ret = rte_eth_rx_queue_setup((uint8_t) portid, 0, nb_rxd, SOCKET0, &rx_conf, lsi_pktmbuf_pool); + if (ret < 0) + rte_exit(EXIT_FAILURE, "rte_eth_rx_queue_setup: err=%d, port=%u\n", ret, portid); + +The list of queues that must be polled for a given lcore is stored in a private structure called struct lcore_queue_conf. + +.. code-block:: c + + struct lcore_queue_conf { + unsigned n_rx_port;

+ +The n_rx_port and rx_port_list[] fields are used in the main packet processing loop +(see `Receive, Process and Transmit Packets`_). + +The global configuration for the RX queues is stored in a static structure: + +.. code-block:: c + + static const struct rte_eth_rxconf rx_conf = { + .rx_thresh = { + .pthresh = RX_PTHRESH, + .hthresh = RX_HTHRESH, + .wthresh = RX_WTHRESH, + }, + }; + +TX Queue Initialization +~~~~~~~~~~~~~~~~~~~~~~~ + +Each lcore should be able to transmit on any port. +For every port, a single TX queue is initialized. + +.. code-block:: c + + /* init one TX queue logical core on each port */ + + fflush(stdout); + + ret = rte_eth_tx_queue_setup(portid, 0, nb_txd, rte_eth_dev_socket_id(portid), &tx_conf); + if (ret < 0) + rte_exit(EXIT_FAILURE, "rte_eth_tx_queue_setup: err=%d,port=%u\n", ret, (unsigned) portid);

+ +Receive, Process and Transmit Packets +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +In the lsi_main_loop() function, the main task is to read ingress packets from the RX queues. +This is done using the following code: + +.. code-block:: c + + /* + * Read packet from RX queues + */ + + for (i = 0; i < qconf->n_rx_port; i++) { + portid = qconf->rx_port_list[i]; + nb_rx = rte_eth_rx_burst((uint8_t) portid, 0, pkts_burst, MAX_PKT_BURST); + port_statistics[portid].rx += nb_rx; + + for (j = 0; j < nb_rx; j++) { + m = pkts_burst[j]; + rte_prefetch0(rte_pktmbuf_mtod(m, void *)); + lsi_simple_forward(m, portid); + } + } + +Packets are read in a burst of size MAX_PKT_BURST. +The rte_eth_rx_burst() function writes the mbuf pointers in a local table and returns the number of available mbufs in the table. + +Then, each mbuf in the table is processed by the lsi_simple_forward() function. +The processing is very simple: processes the TX port from the RX port and then replaces the source and destination MAC addresses. + +.. note:: + + In the following code, the two lines for calculating the output port require some explanation. + If portId is even, the first line does nothing (as portid & 1 will be 0), and the second line adds 1. + If portId is odd, the first line subtracts one and the second line does nothing. + Therefore, 0 goes to 1, and 1 to 0, 2 goes to 3 and 3 to 2, and so on. + +.. code-block:: c + + static void + lsi_simple_forward(struct rte_mbuf *m, unsigned portid) + { + struct ether_hdr *eth; + void *tmp; + unsigned dst_port = lsi_dst_ports[portid]; + + eth = rte_pktmbuf_mtod(m, struct ether_hdr *); + + /* 02:00:00:00:00:xx */ + + tmp = ð->d_addr.addr_bytes[0]; + + *((uint64_t *)tmp) = 0x000000000002 + (dst_port << 40); + + /* src addr */ + ether_addr_copy(&lsi_ports_eth_addr[dst_port], ð->s_addr); + + lsi_send_packet(m, dst_port); + } + +Then, the packet is sent using the lsi_send_packet(m, dst_port) function. +For this test application, the processing is exactly the same for all packets arriving on the same RX port. +Therefore, it would have been possible to call the lsi_send_burst() function directly from the main loop +to send all the received packets on the same TX port using +the burst-oriented send function, which is more efficient. + +However, in real-life applications (such as, L3 routing), +packet N is not necessarily forwarded on the same port as packet N-1. +The application is implemented to illustrate that so the same approach can be reused in a more complex application. + +The lsi_send_packet() function stores the packet in a per-lcore and per-txport table. +If the table is full, the whole packets table is transmitted using the lsi_send_burst() function: + +.. code-block:: c + + /* Send the packet on an output interface */ + + static int + lsi_send_packet(struct rte_mbuf *m, uint16_t port) + { + unsigned lcore_id, len; + struct lcore_queue_conf *qconf; + + lcore_id = rte_lcore_id(); + qconf = &lcore_queue_conf[lcore_id]; + len = qconf->tx_mbufs[port].len; + qconf->tx_mbufs[port].m_table[len] = m; + len++; + + /* enough pkts to be sent */ + + if (unlikely(len == MAX_PKT_BURST)) { + lsi_send_burst(qconf, MAX_PKT_BURST, port); + len = 0; + } + qconf->tx_mbufs[port].len = len; + + return 0; + } + +To ensure that no packets remain in the tables, each lcore does a draining of the TX queue in its main loop. +This technique introduces some latency when there are not many packets to send. +However, it improves performance: + +.. code-block:: c + + cur_tsc = rte_rdtsc(); + + /* + * TX burst queue drain + */ + + diff_tsc = cur_tsc - prev_tsc; + + if (unlikely(diff_tsc > drain_tsc)) { + /* this could be optimized (use queueid instead of * portid), but it is not called so often */ + + for (portid = 0;

specified as auto. +However, omitting the parameter altogether will cause the process to try and start as a primary rather than secondary process. + +Once the process type is specified correctly, +the process starts up, displaying largely similar status messages to the primary instance as it initializes. +Once again, you will be presented with a command prompt. + +Once both processes are running, messages can be sent between them using the send command. +At any stage, either process can be terminated using the quit command. + +.. code-block:: console + + EAL: Master core 10 is ready

the primary instance is terminated, the secondary instance must also be shut-down and restarted after the primary. + This is necessary because the primary instance will clear and reset the shared memory regions on startup, + invalidating the secondary process's pointers. + The secondary process can be stopped and restarted without affecting the primary process. + +How the Application Works +^^^^^^^^^^^^^^^^^^^^^^^^^ + +The core of this example application is based on using two queues and a single memory pool in shared memory. +These three objects are created at startup by the primary process, +since the secondary process cannot create objects in memory as it cannot reserve memory zones, +and the secondary process then uses lookup functions to attach to these objects as it starts up. + +.. code-block:: c + + if (rte_eal_process_type() == RTE_PROC_PRIMARY){ + send_ring = rte_ring_create(_PRI_2_SEC, ring_size, SOCKET0, flags); + recv_ring = rte_ring_create(_SEC_2_PRI, ring_size, SOCKET0, flags); + message_pool = rte_mempool_create(_MSG_POOL, pool_size, string_size, pool_cache, priv_data_sz, NULL, NULL, NULL, NULL, SOCKET0, flags); + } else { + recv_ring = rte_ring_lookup(_PRI_2_SEC); + send_ring = rte_ring_lookup(_SEC_2_PRI); + message_pool = rte_mempool_lookup(_MSG_POOL); + } + +Note, however, that the named ring structure used as send_ring in the primary process is the recv_ring in the secondary process. + +Once the rings and memory pools are all available in both the primary and secondary processes, +the application simply dedicates two threads to sending and receiving messages respectively. +The receive thread simply dequeues any messages on the receive ring, prints them, +and frees the buffer space used by the messages back to the memory pool. +The send thread makes use of the command-prompt library to interactively request user input for messages to send. +Once a send command is issued by the user, a buffer is allocated from the memory pool, filled in with the message contents, +then enqueued on the appropriate rte_ring. + +Symmetric Multi-process Example +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The second example of DPDK multi-process support demonstrates how a set of processes can run in parallel, +with each process performing the same set of packet- processing operations. +(Since each process is identical in functionality to the others, +we refer to this as symmetric multi-processing, to differentiate it from asymmetric multi- processing - +such as a client-server mode of operation seen in the next example, +where different processes perform different tasks, yet co-operate to form a packet-processing system.) +The following diagram shows the data-flow through the application, using two processes. + +.. _figure_sym_multi_proc_app: + +.. figure:: img/sym_multi_proc_app.* + + Example Data Flow in a Symmetric Multi-process Application + + +As the diagram shows, each process reads packets from each of the network ports in use. +RSS is used to distribute incoming packets on each port to different hardware RX queues. +Each process reads a different RX queue on each port and so does not contend with any other process for that queue access. +Similarly, each process writes outgoing packets to a different TX queue on each port. + +Running the Application +^^^^^^^^^^^^^^^^^^^^^^^ + +As with the simple_mp example, the first instance of the symmetric_mp process must be run as the primary instance, +though with a number of other application- specific parameters also provided after the EAL arguments. +These additional parameters are: + +* -p , where portmask is a hexadecimal bitmask of what ports on the system are to be used. + For example: -p 3 to use ports 0 and 1 only. + +* --num-procs , where N is the total number of symmetric_mp instances that will be run side-by-side to perform packet processing. + This parameter is used to configure the appropriate number of receive queues on each network port. + +* --proc-id , where n is a numeric value in the range 0 <= n < N (number of processes, specified above). + This identifies which symmetric_mp instance is being run, so that each process can read a unique receive queue on each network port. + +The secondary symmetric_mp instances must also have these parameters specified, +and the first two must be the same as those passed to the primary instance, or errors result. + +For example, to run a set of four symmetric_mp instances, running on lcores 1-4, +all performing level-2 forwarding of packets between ports 0 and 1, +the following commands can be used (assuming run as root): + +.. code-block:: console + + # ./build/symmetric_mp -l 1 -n 4 --proc-type=auto -- -p 3 --num-procs=4 --proc-id=0 + # ./build/symmetric_mp -l 2 -n 4 --proc-type=auto -- -p 3 --num-procs=4 --proc-id=1 + # ./build/symmetric_mp -l 3 -n 4 --proc-type=auto -- -p 3 --num-procs=4 --proc-id=2 + # ./build/symmetric_mp -l 4 -n 4 --proc-type=auto -- -p 3 --num-procs=4 --proc-id=3 + +.. note:: + + In the above example, the process type can be explicitly specified as primary or secondary, rather than auto. + When using auto, the first process run creates all the memory structures needed for all processes - + irrespective of whether it has a proc-id of 0, 1, 2 or 3. + +.. note:: + + For the symmetric multi-process example, since all processes work in the same manner, + once the hugepage shared memory and the network ports are initialized, + it is not necessary to restart all processes if the primary instance dies. + Instead, that process can be restarted as a secondary, + by explicitly setting the proc-type to secondary on the command line. + (All subsequent instances launched will also need this explicitly specified, + as auto-detection will detect no primary processes running and therefore attempt to re-initialize shared memory.) + +How the Application Works +^^^^^^^^^^^^^^^^^^^^^^^^^ + +The initialization calls in both the primary and secondary instances are the same for the most part, +calling the rte_eal_init(), 1 G and 10 G driver initialization and then rte_pci_probe() functions. +Thereafter, the initialization done depends on whether the process is configured as a primary or secondary instance. + +In the primary instance, a memory pool is created for the packet mbufs and the network ports to be used are initialized - +the number of RX and TX queues per port being determined by the num-procs parameter passed on the command-line. +The structures for the initialized network ports are stored in shared memory and +therefore will be accessible by the secondary process as it initializes. + +.. code-block:: c + + if (num_ports & 1) + rte_exit(EXIT_FAILURE, "Application must use an even number of ports\n"); + + for(i = 0; i < num_ports; i++){ + if(proc_type == RTE_PROC_PRIMARY) + if (smp_port_init(ports[i], mp, (uint16_t)num_procs) < 0) + rte_exit(EXIT_FAILURE, "Error initializing ports\n"); + } + +In the secondary instance, rather than initializing the network ports, the port information exported by the primary process is used, +giving the secondary process access to the hardware and software rings for each network port. +Similarly, the memory pool of mbufs is accessed by doing a lookup for it by name: + +.. code-block:: c + + mp = (proc_type == RTE_PROC_SECONDARY) ? rte_mempool_lookup(_SMP_MBUF_POOL) : rte_mempool_create(_SMP_MBUF_POOL, NB_MBUFS, MBUF_SIZE, ... ) + +Once this initialization is complete, the main loop of each process, both primary and secondary, +is exactly the same - each process reads from each port using the queue corresponding to its proc-id parameter, +and writes to the corresponding transmit queue on the output port. + +Client-Server Multi-process Example +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The third example multi-process application included with the DPDK shows how one can +use a client-server type multi-process design to do packet processing. +In this example, a single server process performs the packet reception from the ports being used and +distributes these packets using round-robin ordering among a set of client processes, +which perform the actual packet processing. +In this case, the client applications just perform level-2 forwarding of packets by sending each packet out on a different network port. + +The following diagram shows the data-flow through the application, using two client processes. + +.. _figure_client_svr_sym_multi_proc_app: + +.. figure:: img/client_svr_sym_multi_proc_app.* + + Example Data Flow in a Client-Server Symmetric Multi-process Application + + +Running the Application +^^^^^^^^^^^^^^^^^^^^^^^ + +The server process must be run initially as the primary process to set up all memory structures for use by the clients. +In addition to the EAL parameters, the application- specific parameters are: + +* -p , where portmask is a hexadecimal bitmask of what ports on the system are to be used. + For example: -p 3 to use ports 0 and 1 only. + +* -n , where the num-clients parameter is the number of client processes that will process the packets received + by the server application. + +.. note:: + + In the server process, a single thread, the master thread, that is, the lowest numbered lcore in the coremask/corelist, performs all packet I/O. + If a coremask/corelist is specified with more than a single lcore bit set in it, + an additional lcore will be used for a thread to periodically print packet count statistics. + +Since the server application stores configuration data in shared memory, including the network ports to be used, +the only application parameter needed by a client process is its client instance ID. +Therefore, to run a server application on lcore 1 (with lcore 2 printing statistics) along with two client processes running on lcores 3 and 4, +the following commands could be used: + +.. code-block:: console + + # ./mp_server/build/mp_server -l 1-2 -n 4 -- -p 3 -n 2 + # ./mp_client/build/mp_client -l 3 -n 4 --proc-type=auto -- -n 0 + # ./mp_client/build/mp_client -l 4 -n 4 --proc-type=auto -- -n 1 + +.. note:: + + If the server application dies and needs to be restarted, all client applications also need to be restarted, + as there is no support in the server application for it to run as a secondary process. + Any client processes that need restarting can be restarted without affecting the server process. + +How the Application Works +^^^^^^^^^^^^^^^^^^^^^^^^^ + +The server process performs the network port and data structure initialization much as the symmetric multi-process application does when run as primary. +One additional enhancement in this sample application is that the server process stores its port configuration data in a memory zone in hugepage shared memory. +This eliminates the need for the client processes to have the portmask parameter passed into them on the command line, +as is done for the symmetric multi-process application, and therefore eliminates mismatched parameters as a potential source of errors. + +In the same way that the server process is designed to be run as a primary process instance only, +the client processes are designed to be run as secondary instances only. +They have no code to attempt to create shared memory objects. +Instead, handles to all needed rings and memory pools are obtained via calls to rte_ring_lookup() and rte_mempool_lookup(). +The network ports for use by the processes are obtained by loading the network port drivers and probing the PCI bus, +which will, as in the symmetric multi-process example, +automatically get access to the network ports using the settings already configured by the primary/server process. + +Once all applications are initialized, the server operates by reading packets from each network port in turn and +distributing those packets to the client queues (software rings, one for each client process) in round-robin order. +On the client side, the packets are read from the rings in as big of bursts as possible, then routed out to a different network port. +The routing used is very simple. All packets received on the first NIC port are transmitted back out on the second port and vice versa. +Similarly, packets are routed between the 3rd and 4th network ports and so on. +The sending of packets is done by writing the packets directly to the network ports; they are not transferred back via the server process. + +In both the server and the client processes, outgoing packets are buffered before being sent, +so as to allow the sending of multiple packets in a single burst to improve efficiency. +For example, the client process will buffer packets to send, +until either the buffer is full or until we receive no further packets from the server. + +Master-slave Multi-process Example +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The fourth example of DPDK multi-process support demonstrates a master-slave model that +provide the capability of application recovery if a slave process crashes or meets unexpected conditions. +In addition, it also demonstrates the floating process, +which can run among different cores in contrast to the traditional way of binding a process/thread to a specific CPU core, +using the local cache mechanism of mempool structures. + +This application performs the same functionality as the L2 Forwarding sample application, +therefore this chapter does not cover that part but describes functionality that is introduced in this multi-process example only. +Please refer to :doc:`l2_forward_real_virtual` for more information. + +Unlike previous examples where all processes are started from the command line with input arguments, in this example, +only one process is spawned from the command line and that process creates other processes. +The following section describes this in more detail. + +Master-slave Process Models +^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The process spawned from the command line is called the *master process* in this document. +A process created by the master is called a *slave process*. +The application has only one master process, but could have multiple slave processes. + +Once the master process begins to run, it tries to initialize all the resources such as +memory, CPU cores, driver, ports, and so on, as the other examples do. +Thereafter, it creates slave processes, as shown in the following figure. + +.. _figure_master_slave_proc: + +.. figure:: img/master_slave_proc.* + + Master-slave Process Workflow + + +The master process calls the rte_eal_mp_remote_launch() EAL function to launch an application function for each pinned thread through the pipe. +Then, it waits to check if any slave processes have exited. +If so, the process tries to re-initialize the resources that belong to that slave and launch them in the pinned thread entry again. +The following section describes the recovery procedures in more detail. + +For each pinned thread in EAL, after reading any data from the pipe, it tries to call the function that the application specified. +In this master specified function, a fork() call creates a slave process that performs the L2 forwarding task. +Then, the function waits until the slave exits, is killed or crashes. Thereafter, it notifies the master of this event and returns. +Finally, the EAL pinned thread waits until the new function is launched. + +After discussing the master-slave model, it is necessary to mention another issue, global and static variables. + +For multiple-thread cases, all global and static variables have only one copy and they can be accessed by any thread if applicable. +So, they can be used to sync or share data among threads. + +In the previous examples, each process has separate global and static variables in memory and are independent of each other. +If it is necessary to share the knowledge, some communication mechanism should be deployed, such as, memzone, ring, shared memory, and so on. +The global or static variables are not a valid approach to share data among processes. +For variables in this example, on the one hand, the slave process inherits all the knowledge of these variables after being created by the master. +On the other hand, other processes cannot know if one or more processes modifies them after slave creation since that +is the nature of a multiple process address space. +But this does not mean that these variables cannot be used to share or sync data; it depends on the use case. +The following are the possible use cases: + +#. The master process starts and initializes a variable and it will never be changed after slave processes created. This case is OK. + +#. After the slave processes are created, the master or slave cores need to change a variable, but other processes do not need to know the change. + This case is also OK. + +#. After the slave processes are created, the master or a slave needs to change a variable. + In the meantime, one or more other process needs to be aware of the change. + In this case, global and static variables cannot be used to share knowledge. Another communication mechanism is needed. + A simple approach without lock protection can be a heap buffer allocated by rte_malloc or mem zone. + +Slave Process Recovery Mechanism +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +Before talking about the recovery mechanism, it is necessary to know what is needed before a new slave instance can run if a previous one exited. + +When a slave process exits, the system returns all the resources allocated for this process automatically. +However, this does not include the resources that were allocated by the DPDK. All the hardware resources are shared among the processes, +which include memzone, mempool, ring, a heap buffer allocated by the rte_malloc library, and so on. +If the new instance runs and the allocated resource is not returned, either resource allocation failed or the hardware resource is lost forever. + +When a slave process runs, it may have dependencies on other processes. +They could have execution sequence orders; they could share the ring to communicate; they could share the same port for reception and forwarding; +they could use lock structures to do exclusive access in some critical path. +What happens to the dependent process(es) if the peer leaves? +The consequence are varied since the dependency cases are complex. +It depends on what the processed had shared. +However, it is necessary to notify the peer(s) if one slave exited. +Then, the peer(s) will be aware of that and wait until the new instance begins to run. + +Therefore, to provide the capability to resume the new slave instance if the previous one exited, it is necessary to provide several mechanisms: + +#. Keep a resource list for each slave process. + Before a slave process run, the master should prepare a resource list. + After it exits, the master could either delete the allocated resources and create new ones, + or re-initialize those for use by the new instance. + +#. Set up a notification mechanism for slave process exit cases. After the specific slave leaves, + the master should be notified and then help to create a new instance. + This mechanism is provided in Section `Master-slave Process Models`_. + +#. Use a synchronization mechanism among dependent processes. + The master should have the capability to stop or kill slave processes that have a dependency on the one that has exited. + Then, after the new instance of exited slave process begins to run, the dependency ones could resume or run from the start. + The example sends a STOP command to slave processes dependent on the exited one, then they will exit. + Thereafter, the master creates new instances for the exited slave processes. + +The following diagram describes slave process recovery. + +.. _figure_slave_proc_recov: + +.. figure:: img/slave_proc_recov.* + + Slave Process Recovery Process Flow + + +Floating Process Support +^^^^^^^^^^^^^^^^^^^^^^^^ + +When the DPDK application runs, there is always a -c option passed in to indicate the cores that are enabled. +Then, the DPDK creates a thread for each enabled core. +By doing so, it creates a 1:1 mapping between the enabled core and each thread. +The enabled core always has an ID, therefore, each thread has a unique core ID in the DPDK execution environment. +With the ID, each thread can easily access the structures or resources exclusively belonging to it without using function parameter passing. +It can easily use the rte_lcore_id() function to get the value in every function that is called. + +For threads/processes not created in that way, either pinned to a core or not, they will not own a unique ID and the +rte_lcore_id() function will not work in the correct way. +However, sometimes these threads/processes still need the unique ID mechanism to do easy access on structures or resources. +For example, the DPDK mempool library provides a local cache mechanism +(refer to :ref:`mempool_local_cache`) +for fast element allocation and freeing. +If using a non-unique ID or a fake one, +a race condition occurs if two or more threads/ processes with the same core ID try to use the local cache. + +Therefore, unused core IDs from the passing of parameters with the -c option are used to organize the core ID allocation array. +Once the floating process is spawned, it tries to allocate a unique core ID from the array and release it on exit. + +A natural way to spawn a floating process is to use the fork() function and allocate a unique core ID from the unused core ID array. +However, it is necessary to write new code to provide a notification mechanism for slave exit +and make sure the process recovery mechanism can work with it. + +To avoid producing redundant code, the Master-Slave process model is still used to spawn floating processes, +then cancel the affinity to specific cores. +Besides that, clear the core ID assigned to the DPDK spawning a thread that has a 1:1 mapping with the core mask. +Thereafter, get a new core ID from the unused core ID allocation array. + +Run the Application +^^^^^^^^^^^^^^^^^^^ + +This example has a command line similar to the L2 Forwarding sample application with a few differences. + +To run the application, start one copy of the l2fwd_fork binary in one terminal. +Unlike the L2 Forwarding example, +this example requires at least three cores since the master process will wait and be accountable for slave process recovery. +The command is as follows: + +.. code-block:: console + + #./build/l2fwd_fork -l 2-4 -n 4 -- -p 3 -f + +This example provides another -f option to specify the use of floating process. +If not specified, the example will use a pinned process to perform the L2 forwarding task. + +To verify the recovery mechanism, proceed as follows: First, check the PID of the slave processes: + +.. code-block:: console + + #ps -fe | grep l2fwd_fork + root 5136 4843 29 11:11 pts/1 00:00:05 ./build/l2fwd_fork + root 5145 5136 98 11:11 pts/1 00:00:11 ./build/l2fwd_fork + root 5146 5136 98 11:11 pts/1 00:00:11 ./build/l2fwd_fork + +Then, kill one of the slaves: + +.. code-block:: console + + #kill -9 5145 + +After 1 or 2 seconds, check whether the slave has resumed: + +.. code-block:: console + + #ps -fe | grep l2fwd_fork + root 5136 4843 3 11:11 pts/1 00:00:06 ./build/l2fwd_fork + root 5247 5136 99 11:14 pts/1 00:00:01 ./build/l2fwd_fork + root 5248 5136 99 11:14 pts/1 00:00:01 ./build/l2fwd_fork + +It can also monitor the traffic generator statics to see whether slave processes have resumed. + +Explanation +^^^^^^^^^^^ + +As described in previous sections, +not all global and static variables need to change to be accessible in multiple processes; +it depends on how they are used. +In this example, +the statics info on packets dropped/forwarded/received count needs to be updated by the slave process, +and the master needs to see the update and print them out. +So, it needs to allocate a heap buffer using rte_zmalloc. +In addition, if the -f option is specified, +an array is needed to store the allocated core ID for the floating process so that the master can return it +after a slave has exited accidentally. + +.. code-block:: c + + static int + l2fwd_malloc_shared_struct(void) + { + port_statistics = rte_zmalloc("port_stat", sizeof(struct l2fwd_port_statistics) * RTE_MAX_ETHPORTS, 0); + + if (port_statistics == NULL) + return -1; + + /* allocate mapping_id array */ + + if (float_proc) { + int i; + + mapping_id = rte_malloc("mapping_id", sizeof(unsigned) * RTE_MAX_LCORE, 0); + if (mapping_id == NULL) + return -1; + + for (i = 0 ;i < RTE_MAX_LCORE; i++) + mapping_id[i] = INVALID_MAPPING_ID; + + } + return 0; + } + +For each slave process, packets are received from one port and forwarded to another port that another slave is operating on. +If the other slave exits accidentally, the port it is operating on may not work normally, +so the first slave cannot forward packets to that port. +There is a dependency on the port in this case. So, the master should recognize the dependency. +The following is the code to detect this dependency: + +.. code-block:: c + + for (portid = 0; portid < nb_ports; portid++) { + /* skip ports that are not enabled */ + + if ((l2fwd_enabled_port_mask & (1 << portid)) == 0) + continue; + + /* Find pair ports' lcores */ + + find_lcore = find_pair_lcore = 0; + pair_port = l2fwd_dst_ports[portid]; + + for (i = 0; i < RTE_MAX_LCORE; i++) { + if (!rte_lcore_is_enabled(i)) + continue; + + for (j = 0; j < lcore_queue_conf[i].n_rx_port;j++) { + if (lcore_queue_conf[i].rx_port_list[j] == portid) { + lcore = i; + find_lcore = 1; + break; + } + + if (lcore_queue_conf[i].rx_port_list[j] == pair_port) { + pair_lcore = i; + find_pair_lcore = 1; + break; + } + } + + if (find_lcore && find_pair_lcore) + break; + } + + if (!find_lcore || !find_pair_lcore) + rte_exit(EXIT_FAILURE, "Not find port=%d pair\\n", portid); + + printf("lcore %u and %u paired\\n", lcore, pair_lcore); + + lcore_resource[lcore].pair_id = pair_lcore; + lcore_resource[pair_lcore].pair_id = lcore; + } + +Before launching the slave process, +it is necessary to set up the communication channel between the master and slave so that +the master can notify the slave if its peer process with the dependency exited. +In addition, the master needs to register a callback function in the case where a specific slave exited. + +.. code-block:: c + + for (i = 0; i < RTE_MAX_LCORE; i++) { + if (lcore_resource[i].enabled) { + /* Create ring for master and slave communication */ + + ret = create_ms_ring(i); + if (ret != 0) + rte_exit(EXIT_FAILURE, "Create ring for lcore=%u failed",i); + + if (flib_register_slave_exit_notify(i,slave_exit_cb) != 0) + rte_exit(EXIT_FAILURE, "Register master_trace_slave_exit failed"); + } + } + +After launching the slave process, the master waits and prints out the port statics periodically. +If an event indicating that a slave process exited is detected, +it sends the STOP command to the peer and waits until it has also exited. +Then, it tries to clean up the execution environment and prepare new resources. +Finally, the new slave instance is launched. + +.. code-block:: c + + while (1) { + sleep(1); + cur_tsc = rte_rdtsc(); + diff_tsc = cur_tsc - prev_tsc; + + /* if timer is enabled */ + + if (timer_period > 0) { + /* advance the timer */ + timer_tsc += diff_tsc; + + /* if timer has reached its timeout */ + if (unlikely(timer_tsc >= (uint64_t) timer_period)) { + print_stats(); + + /* reset the timer */ + timer_tsc = 0; + } + } + + prev_tsc = cur_tsc; + + /* Check any slave need restart or recreate */ + + rte_spinlock_lock(&res_lock); + + for (i = 0; i < RTE_MAX_LCORE; i++) { + struct lcore_resource_struct *res = &lcore_resource[i]; + struct lcore_resource_struct *pair = &lcore_resource[res->pair_id]; + + /* If find slave exited, try to reset pair */ + + if (res->enabled && res->flags && pair->enabled) { + if (!pair->flags) { + master_sendcmd_with_ack(pair->lcore_id, CMD_STOP); + rte_spinlock_unlock(&res_lock); + sleep(1); + rte_spinlock_lock(&res_lock); + if (pair->flags) + continue; + } + + if (reset_pair(res->lcore_id, pair->lcore_id) != 0) + rte_exit(EXIT_FAILURE, "failed to reset slave"); + + res->flags = 0; + pair->flags = 0; + } + } + rte_spinlock_unlock(&res_lock); + } + +When the slave process is spawned and starts to run, it checks whether the floating process option is applied. +If so, it clears the affinity to a specific core and also sets the unique core ID to 0. +Then, it tries to allocate a new core ID. +Since the core ID has changed, the resource allocated by the master cannot work, +so it remaps the resource to the new core ID slot. + +.. code-block:: c + + static int + l2fwd_launch_one_lcore( attribute ((unused)) void *dummy) + { + unsigned lcore_id = rte_lcore_id(); + + if (float_proc) { + unsigned flcore_id; + + /* Change it to floating process, also change it's lcore_id */ + + clear_cpu_affinity(); + + RTE_PER_LCORE(_lcore_id) = 0; + + /* Get a lcore_id */ + + if (flib_assign_lcore_id() < 0 ) { + printf("flib_assign_lcore_id failed\n"); + return -1; + } + + flcore_id = rte_lcore_id(); + + /* Set mapping id, so master can return it after slave exited */ + + mapping_id[lcore_id] = flcore_id; + printf("Org lcore_id = %u, cur lcore_id = %u\n",lcore_id, flcore_id); + remapping_slave_resource(lcore_id, flcore_id); + } + + l2fwd_main_loop(); + + /* return lcore_id before return */ + if (float_proc) { + flib_free_lcore_id(rte_lcore_id()); + mapping_id[lcore_id] = INVALID_MAPPING_ID; + } + return 0; + } diff --git a/dpdk/doc/guides/sample_app_ug/netmap_compatibility.rst b/dpdk/doc/guides/sample_app_ug/netmap_compatibility.rst new file mode 100644 index 0000000..33b1cc2 --- /dev/null +++ b/dpdk/doc/guides/sample_app_ug/netmap_compatibility.rst @@ -0,0 +1,130 @@ +..

+The Netmap compatibility library provides a minimal set of APIs to give programs written against the Netmap APIs +the ability to be run, with minimal changes to their source code, using the DPDK to perform the actual packet I/O. + +Since Netmap applications use regular system calls, like ``open()``, ``ioctl()`` and +``mmap()`` to communicate with the Netmap kernel module performing the packet I/O, +the ``compat_netmap`` library provides a set of similar APIs to use in place of those system calls, +effectively turning a Netmap application into a DPDK application. + +The provided library is currently minimal and doesn't support all the features that Netmap supports, +but is enough to run simple applications, such as the bridge example detailed below. + +Knowledge of Netmap is required to understand the rest of this section. +Please refer to the Netmap distribution for details about Netmap. + +Available APIs +-------------- + +The library provides the following drop-in replacements for system calls usually used in Netmap applications: + +* ``rte_netmap_close()`` + +* ``rte_netmap_ioctl()`` + +* ``rte_netmap_open()`` + +* ``rte_netmap_mmap()`` + +* ``rte_netmap_poll()`` + +They use the same signature as their libc counterparts, and can be used as drop-in replacements in most cases. + +Caveats +------- + +Given the difference between the way Netmap and the DPDK approach packet I/O, +there are caveats and limitations to be aware of when trying to use the ``compat_netmap`` library, the most important of these are listed below. +These may change as the library is updated: + +* Any system call that can potentially affect file descriptors cannot be used with a descriptor returned by the ``rte_netmap_open()`` function. + +Note that: + +* The ``rte_netmap_mmap()`` function merely returns the address of a DPDK memzone. + The address, length, flags, offset, and other arguments are ignored. + +* The ``rte_netmap_poll()`` function only supports infinite (negative) or zero time outs. + It effectively turns calls to the ``poll()`` system call made in a Netmap application into polling of the DPDK ports, + changing the semantics of the usual POSIX defined poll. + +* Not all of Netmap's features are supported: host rings, + slot flags and so on are not supported or are simply not relevant in the DPDK model. + +* The Netmap manual page states that "*a device obtained through /dev/netmap also supports the ioctl supported by network devices*". + This is not the case with this compatibility layer. + +* The Netmap kernel module exposes a sysfs interface to change some internal parameters, such as the size of the shared memory region. + This interface is not available when using this compatibility layer. + +Porting Netmap Applications +--------------------------- + +Porting Netmap applications typically involves two major steps: + +* Changing the system calls to use their ``compat_netmap`` library counterparts. + +* Adding further DPDK initialization code. + +Since the ``compat_netmap`` functions have the same signature as the usual libc calls, the change is trivial in most cases. + +The usual DPDK initialization code involving ``rte_eal_init()`` and ``rte_pci_probe()`` +has to be added to the Netmap application in the same way it is used in all other DPDK sample applications. +Please refer to the *DPDK Programmer's Guide* and example source code for details about initialization. + +In addition of the regular DPDK initialization code, +the ported application needs to call initialization functions for the ``compat_netmap`` library, +namely ``rte_netmap_init()`` and ``rte_netmap_init_port()``. + +These two initialization functions take ``compat_netmap`` specific data structures as parameters: +``struct rte_netmap_conf`` and ``struct rte_netmap_port_conf``. +The structures' fields are Netmap related and are self-explanatory for developers familiar with Netmap. +They are defined in ``$RTE_SDK/examples/netmap_compat/lib/compat_netmap.h``. + +The bridge application is an example largely based on the bridge example shipped with the Netmap distribution. +It shows how a minimal Netmap application with minimal and straightforward source code changes can be run on top of the DPDK. +Please refer to ``$RTE_SDK/examples/netmap_compat/bridge/bridge.c`` for an example of a ported application. + +Compiling the Application +------------------------- + +To compile the sample application see :doc:`compiling`. + +The application is located in the ``netmap_compat`` sub-directory. + +Running the "bridge" Sample Application +--------------------------------------- + +The application requires a single command line option: + +.. code-block:: console + + ./build/bridge [EAL options] -- -i INTERFACE_A [-i INTERFACE_B] + +where, + +* ``-i INTERFACE``: Interface (DPDK port number) to use. + + If a single ``-i`` parameter is given, the interface will send back all the traffic it receives. + If two ``-i`` parameters are given, the two interfaces form a bridge, + where traffic received on one interface is replicated and sent to the other interface. + +For example, to run the application in a linuxapp environment using port 0 and 2: + +.. code-block:: console + + ./build/bridge [EAL options] -- -i 0 -i 2 + +Refer to the *DPDK Getting Started Guide for Linux* for general information on running applications and +the Environment Abstraction Layer (EAL) options. + +Note that unlike a traditional bridge or the ``l2fwd`` sample application, no MAC address changes are done

With respect to these rings the RX threads +are producers and the TX threads are consumers. + +On initialization the TX and RX threads are started according to the command +line parameters. + +The RX threads poll the network interface queues and post received packets to a +TX thread via a corresponding software ring. + +The TX threads poll software rings, perform the L3 forwarding hash/LPM match, +and assemble packet bursts before performing burst transmit on the network +interface. + +As with the standard L3 forward application, burst draining of residual packets +is performed periodically with the period calculated from elapsed time using +the timestamps counter. + +The diagram below illustrates a case with two RX threads and three TX threads. + +.. _figure_performance_thread_1: + +.. figure:: img/performance_thread_1.* + + +Mode of operation with L-threads +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Like the EAL thread configuration the application has split the RX and TX +functionality into different threads, and the pairs of RX and TX threads are +interconnected via software rings. + +On initialization an L-thread scheduler is started on every EAL thread. On all +but the master EAL thread only a a dummy L-thread is initially started. +The L-thread started on the master EAL thread then spawns other L-threads on +different L-thread schedulers according the command line parameters. + +The RX threads poll the network interface queues and post received packets +to a TX thread via the corresponding software ring. + +The ring interface is augmented by means of an L-thread condition variable that +enables the TX thread to be suspended when the TX ring is empty. The RX thread +signals the condition whenever it posts to the TX ring, causing the TX thread +to be resumed. + +Additionally the TX L-thread spawns a worker L-thread to take care of +polling the software rings, whilst it handles burst draining of the transmit +buffer. + +The worker threads poll the software rings, perform L3 route lookup and +assemble packet bursts. If the TX ring is empty the worker thread suspends +itself by waiting on the condition variable associated with the ring. + +Burst draining of residual packets, less than the burst size, is performed by +the TX thread which sleeps (using an L-thread sleep function) and resumes +periodically to flush the TX buffer. + +This design means that L-threads that have no work, can yield the CPU to other +L-threads and avoid having to constantly poll the software rings. + +The diagram below illustrates a case with two RX threads and three TX functions +(each comprising a thread that processes forwarding and a thread that +periodically drains the output buffer of residual packets). + +.. _figure_performance_thread_2: + +.. figure:: img/performance_thread_2.* + + +CPU load statistics +~~~~~~~~~~~~~~~~~~~ + +It is possible to display statistics showing estimated CPU load on each core. +The statistics indicate the percentage of CPU time spent: processing +received packets (forwarding), polling queues/rings (waiting for work), +and doing any other processing (context switch and other overhead). + +When enabled statistics are gathered by having the application threads set and +clear flags when they enter and exit pertinent code sections. The flags are +then sampled in real time by a statistics collector thread running on another +core. This thread displays the data in real time on the console. + +This feature is enabled by designating a statistics collector core, using the +``--stat-lcore`` parameter. + + +.. _lthread_subsystem: + +The L-thread subsystem +---------------------- + +The L-thread subsystem resides in the examples/performance-thread/common +directory and is built and linked automatically when building the +``l3fwd-thread`` example. + +The subsystem provides a simple cooperative scheduler to enable arbitrary +functions to run as cooperative threads within a single EAL thread. +The subsystem provides a pthread like API that is intended to assist in +reuse of legacy code written for POSIX pthreads. + +The following sections provide some detail on the features, constraints, +performance and porting considerations when using L-threads. + + +.. _comparison_between_lthreads_and_pthreads: + +Comparison between L-threads and POSIX pthreads +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The fundamental difference between the L-thread and pthread models is the +way in which threads are scheduled. The simplest way to think about this is to +consider the case of a processor with a single CPU. To run multiple threads +on a single CPU, the scheduler must frequently switch between the threads, +in order that each thread is able to make timely progress. +This is the basis of any multitasking operating system. + +This section explores the differences between the pthread model and the +L-thread model as implemented in the provided L-thread subsystem. If needed a +theoretical discussion of preemptive vs cooperative multi-threading can be +found in any good text on operating system design. + + +Scheduling and context switching +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The POSIX pthread library provides an application programming interface to +create and synchronize threads. Scheduling policy is determined by the host OS, +and may be configurable. The OS may use sophisticated rules to determine which +thread should be run next, threads may suspend themselves or make other threads +ready, and the scheduler may employ a time slice giving each thread a maximum +time quantum after which it will be preempted in favor of another thread that +is ready to run. To complicate matters further threads may be assigned +different scheduling priorities. + +By contrast the L-thread subsystem is considerably simpler. Logically the +L-thread scheduler performs the same multiplexing function for L-threads +within a single pthread as the OS scheduler does for pthreads within an +application process. The L-thread scheduler is simply the main loop of a +pthread, and in so far as the host OS is concerned it is a regular pthread +just like any other. The host OS is oblivious about the existence of and +not at all involved in the scheduling of L-threads. + +The other and most significant difference between the two models is that +L-threads are scheduled cooperatively. L-threads cannot not preempt each +other, nor can the L-thread scheduler preempt a running L-thread (i.e. +there is no time slicing). The consequence is that programs implemented with +L-threads must possess frequent rescheduling points, meaning that they must +explicitly and of their own volition return to the scheduler at frequent +intervals, in order to allow other L-threads an opportunity to proceed. + +In both models switching between threads requires that the current CPU +context is saved and a new context (belonging to the next thread ready to run) +is restored. With pthreads this context switching is handled transparently +and the set of CPU registers that must be preserved between context switches +is as per an interrupt handler. + +An L-thread context switch is achieved by the thread itself making a function +call to the L-thread scheduler. Thus it is only necessary to preserve the +callee registers. The caller is responsible to save and restore any other +registers it is using before a function call, and restore them on return, +and this is handled by the compiler. For ``X86_64`` on both Linux and BSD the +System V calling convention is used, this defines registers RSP, RBP, and +R12-R15 as callee-save registers (for more detailed discussion a good reference +is `X86 Calling Conventions `_). + +Taking advantage of this, and due to the absence of preemption, an L-thread +context switch is achieved with less than 20 load/store instructions. + +The scheduling policy for L-threads is fixed, there is no prioritization of +L-threads, all L-threads are equal and scheduling is based on a FIFO +ready queue. + +An L-thread is a struct containing the CPU context of the thread +(saved on context switch) and other useful items. The ready queue contains +pointers to threads that are ready to run. The L-thread scheduler is a simple +loop that polls the ready queue, reads from it the next thread ready to run, +which it resumes by saving the current context (the current position in the +scheduler loop) and restoring the context of the next thread from its thread +struct. Thus an L-thread is always resumed at the last place it yielded. + +A well behaved L-thread will call the context switch regularly (at least once +in its main loop) thus returning to the scheduler's own main loop. Yielding +inserts the current thread at the back of the ready queue, and the process of +servicing the ready queue is repeated, thus the system runs by flipping back +and forth the between L-threads and scheduler loop. + +In the case of pthreads, the preemptive scheduling, time slicing, and support +for thread prioritization means that progress is normally possible for any +thread that is ready to run. This comes at the price of a relatively heavier +context switch and scheduling overhead. + +With L-threads the progress of any particular thread is determined by the +frequency of rescheduling opportunities in the other L-threads. This means that +an errant L-thread monopolizing the CPU might cause scheduling of other threads +to be stalled. Due to the lower cost of context switching, however, voluntary +rescheduling to ensure progress of other threads, if managed sensibly, is not +a prohibitive overhead, and overall performance can exceed that of an +application using pthreads. + + +Mutual exclusion +^^^^^^^^^^^^^^^^ + +With pthreads preemption means that threads that share data must observe +some form of mutual exclusion protocol. + +The fact that L-threads cannot preempt each other means that in many cases +mutual exclusion devices can be completely avoided. + +Locking to protect shared data can be a significant bottleneck in +multi-threaded applications so a carefully designed cooperatively scheduled +program can enjoy significant performance advantages. + +So far we have considered only the simplistic case of a single core CPU, +when multiple CPUs are considered things are somewhat more complex. + +First of all it is inevitable that there must be multiple L-thread schedulers, +one running on each EAL thread. So long as these schedulers remain isolated +from each other the above assertions about the potential advantages of +cooperative scheduling hold true. + +A configuration with isolated cooperative schedulers is less flexible than the +pthread model where threads can be affinitized to run on any CPU. With isolated +schedulers scaling of applications to utilize fewer or more CPUs according to +system demand is very difficult to achieve. + +The L-thread subsystem makes it possible for L-threads to migrate between +schedulers running on different CPUs. Needless to say if the migration means +that threads that share data end up running on different CPUs then this will +introduce the need for some kind of mutual exclusion system. + +Of course ``rte_ring`` software rings can always be used to interconnect +threads running on different cores, however to protect other kinds of shared +data structures, lock free constructs or else explicit locking will be +required. This is a consideration for the application design. + +In support of this extended functionality, the L-thread subsystem implements +thread safe mutexes and condition variables. + +The cost of affinitizing and of condition variable signaling is significantly +lower than the equivalent pthread operations, and so applications using these +features will see a performance benefit. + + +Thread local storage +^^^^^^^^^^^^^^^^^^^^ + +As with applications written for pthreads an application written for L-threads +can take advantage of thread local storage, in this case local to an L-thread. +An application may save and retrieve a single pointer to application data in +the L-thread struct. + +For legacy and backward compatibility reasons two alternative methods are also +offered, the first is modelled directly on the pthread get/set specific APIs, +the second approach is modelled on the ``RTE_PER_LCORE`` macros, whereby +``PER_LTHREAD`` macros are introduced, in both cases the storage is local to +the L-thread. + + +.. _constraints_and_performance_implications: + +Constraints and performance implications when using L-threads +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + + +.. _API_compatibility: + +API compatibility +^^^^^^^^^^^^^^^^^ + +The L-thread subsystem provides a set of functions that are logically equivalent +to the corresponding functions offered by the POSIX pthread library, however not +all pthread functions have a corresponding L-thread equivalent, and not all +features available to pthreads are implemented for L-threads. + +The pthread library offers considerable flexibility via programmable attributes +that can be associated with threads, mutexes, and condition variables. + +By contrast the L-thread subsystem has fixed functionality, the scheduler policy +cannot be varied, and L-threads cannot be prioritized. There are no variable +attributes associated with any L-thread objects. L-threads, mutexes and +conditional variables, all have fixed functionality. (Note: reserved parameters +are included in the APIs to facilitate possible future support for attributes). + +The table below lists the pthread and equivalent L-thread APIs with notes on +differences and/or constraints. Where there is no L-thread entry in the table, +then the L-thread subsystem provides no equivalent function. + +.. _table_lthread_pthread: + +.. table:: Pthread and equivalent L-thread APIs. + +

The context switch time as measured from immediately before the call to +``lthread_yield()`` to the point at which the next ready thread is resumed, +can be an order of magnitude faster that the same measurement for +pthread_yield. + + +**Note 8**: + +``lthread_set_affinity()`` is similar to a yield apart from the fact that the +yielding thread is inserted into a peer ready queue of another scheduler. +The peer ready queue is actually a separate thread safe queue, which means that +threads appearing in the peer ready queue can jump any backlog in the local +ready queue on the destination scheduler. + +The context switch time as measured from the time just before the call to +``lthread_set_affinity()`` to just after the same thread is resumed on the new +scheduler can be orders of magnitude faster than the same measurement for +``pthread_setaffinity_np()``. + + +**Note 9**: + +Although there is no ``pthread_sleep()`` function, ``lthread_sleep()`` and +``lthread_sleep_clks()`` can be used wherever ``sleep()``, ``usleep()`` or +``nanosleep()`` might ordinarily be used. The L-thread sleep functions suspend +the current thread, start an ``rte_timer`` and resume the thread when the +timer matures. The ``rte_timer_manage()`` entry point is called on every pass +of the scheduler loop. This means that the worst case jitter on timer expiry +is determined by the longest period between context switches of any running +L-threads. + +In a synthetic test with many threads sleeping and resuming then the measured +jitter is typically orders of magnitude lower than the same measurement made +for ``nanosleep()``. + + +**Note 10**: + +Spin locks are not provided because they are problematical in a cooperative +environment, see :ref:`porting_locks_and_spinlocks` for a more detailed +discussion on how to avoid spin locks. + + +.. _Thread_local_storage_performance: + +Thread local storage +^^^^^^^^^^^^^^^^^^^^ + +Of the three L-thread local storage options the simplest and most efficient is +storing a single application data pointer in the L-thread struct. + +The ``PER_LTHREAD`` macros involve a run time computation to obtain the address +of the variable being saved/retrieved and also require that the accesses are +de-referenced via a pointer. This means that code that has used +``RTE_PER_LCORE`` macros being ported to L-threads might need some slight +adjustment (see :ref:`porting_thread_local_storage` for hints about porting +code that makes use of thread local storage). + +The get/set specific APIs are consistent with their pthread counterparts both +in use and in performance. + + +.. _memory_allocation_and_NUMA_awareness: + +Memory allocation and NUMA awareness +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +All memory allocation is from DPDK huge pages, and is NUMA aware. Each +scheduler maintains its own caches of objects: lthreads, their stacks, TLS, +mutexes and condition variables. These caches are implemented as unbounded lock +free MPSC queues. When objects are created they are always allocated from the +caches on the local core (current EAL thread). + +If an L-thread has been affinitized to a different scheduler, then it can +always safely free resources to the caches from which they originated (because +the caches are MPSC queues). + +If the L-thread has been affinitized to a different NUMA node then the memory +resources associated with it may incur longer access latency. + +The commonly used pattern of setting affinity on entry to a thread after it has +started, means that memory allocation for both the stack and TLS will have been +made from caches on the NUMA node on which the threads creator is running. +This has the side effect that access latency will be sub-optimal after +affinitizing. + +This side effect can be mitigated to some extent (although not completely) by +specifying the destination CPU as a parameter of ``lthread_create()`` this +causes the L-thread's stack and TLS to be allocated when it is first scheduled +on the destination scheduler, if the destination is a on another NUMA node it +results in a more optimal memory allocation. + +Note that the lthread struct itself remains allocated from memory on the +creating node, this is unavoidable because an L-thread is known everywhere by +the address of this struct. + + +.. _object_cache_sizing: + +Object cache sizing +^^^^^^^^^^^^^^^^^^^ + +The per lcore object caches pre-allocate objects in bulk whenever a request to +allocate an object finds a cache empty. By default 100 objects are +pre-allocated, this is defined by ``LTHREAD_PREALLOC`` in the public API +header file lthread_api.h. This means that the caches constantly grow to meet +system demand. + +In the present implementation there is no mechanism to reduce the cache sizes +if system demand reduces. Thus the caches will remain at their maximum extent +indefinitely. + +A consequence of the bulk pre-allocation of objects is that every 100 (default +value) additional new object create operations results in a call to +``rte_malloc()``. For creation of objects such as L-threads, which trigger the +allocation of even more objects (i.e. their stacks and TLS) then this can +cause outliers in scheduling performance. + +If this is a problem the simplest mitigation strategy is to dimension the +system, by setting the bulk object pre-allocation size to some large number +that you do not expect to be exceeded. This means the caches will be populated +once only, the very first time a thread is created. + + +.. _Ready_queue_backlog: + +Ready queue backlog +^^^^^^^^^^^^^^^^^^^ + +One of the more subtle performance considerations is managing the ready queue +backlog. The fewer threads that are waiting in the ready queue then the faster +any particular thread will get serviced. + +In a naive L-thread application with N L-threads simply looping and yielding, +this backlog will always be equal to the number of L-threads, thus the cost of +a yield to a particular L-thread will be N times the context switch time. + +This side effect can be mitigated by arranging for threads to be suspended and +wait to be resumed, rather than polling for work by constantly yielding. +Blocking on a mutex or condition variable or even more obviously having a +thread sleep if it has a low frequency workload are all mechanisms by which a +thread can be excluded from the ready queue until it really does need to be +run. This can have a significant positive impact on performance. + + +.. _Initialization_and_shutdown_dependencies: + +Initialization, shutdown and dependencies +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The L-thread subsystem depends on DPDK for huge page allocation and depends on +the ``rte_timer subsystem``. The DPDK EAL initialization and +``rte_timer_subsystem_init()`` **MUST** be completed before the L-thread sub +system can be used. + +Thereafter initialization of the L-thread subsystem is largely transparent to +the application. Constructor functions ensure that global variables are properly +initialized. Other than global variables each scheduler is initialized +independently the first time that an L-thread is created by a particular EAL +thread. + +If the schedulers are to be run as isolated and independent schedulers, with +no intention that L-threads running on different schedulers will migrate between +schedulers or synchronize with L-threads running on other schedulers, then +initialization consists simply of creating an L-thread, and then running the +L-thread scheduler. + +If there will be interaction between L-threads running on different schedulers, +then it is important that the starting of schedulers on different EAL threads +is synchronized. + +To achieve this an additional initialization step is necessary, this is simply +to set the number of schedulers by calling the API function +``lthread_num_schedulers_set(n)``, where ``n`` is the number of EAL threads +that will run L-thread schedulers. Setting the number of schedulers to a +number greater than 0 will cause all schedulers to wait until the others have +started before beginning to schedule L-threads. + +The L-thread scheduler is started by calling the function ``lthread_run()`` +and should be called from the EAL thread and thus become the main loop of the +EAL thread. + +The function ``lthread_run()``, will not return until all threads running on +the scheduler have exited, and the scheduler has been explicitly stopped by +calling ``lthread_scheduler_shutdown(lcore)`` or +``lthread_scheduler_shutdown_all()``. + +All these function do is tell the scheduler that it can exit when there are no +longer any running L-threads, neither function forces any running L-thread to +terminate. Any desired application shutdown behavior must be designed and +built into the application to ensure that L-threads complete in a timely +manner. + +**Important Note:** It is assumed when the scheduler exits that the application +is terminating for good, the scheduler does not free resources before exiting +and running the scheduler a subsequent time will result in undefined behavior. + + +.. _porting_legacy_code_to_run_on_lthreads: + +Porting legacy code to run on L-threads +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Legacy code originally written for a pthread environment may be ported to +L-threads if the considerations about differences in scheduling policy, and +constraints discussed in the previous sections can be accommodated. + +This section looks in more detail at some of the issues that may have to be +resolved when porting code. + + +.. _pthread_API_compatibility: + +pthread API compatibility +^^^^^^^^^^^^^^^^^^^^^^^^^ + +The first step is to establish exactly which pthread APIs the legacy +application uses, and to understand the requirements of those APIs. If there +are corresponding L-lthread APIs, and where the default pthread functionality +is used by the application then, notwithstanding the other issues discussed +here, it should be feasible to run the application with L-threads. If the +legacy code modifies the default behavior using attributes then if may be +necessary to make some adjustments to eliminate those requirements. + + +.. _blocking_system_calls: + +Blocking system API calls +^^^^^^^^^^^^^^^^^^^^^^^^^ + +It is important to understand what other system services the application may be +using, bearing in mind that in a cooperatively scheduled environment a thread +cannot block without stalling the scheduler and with it all other cooperative +threads. Any kind of blocking system call, for example file or socket IO, is a +potential problem, a good tool to analyze the application for this purpose is +the ``strace`` utility. + +There are many strategies to resolve these kind of issues, each with it +merits. Possible solutions include: + +* Adopting a polled mode of the system API concerned (if available). + +* Arranging for another core to perform the function and synchronizing with + that core via constructs that will not block the L-thread. + +* Affinitizing the thread to another scheduler devoted (as a matter of policy) + to handling threads wishing to make blocking calls, and then back again when + finished. + + +.. _porting_locks_and_spinlocks: + +Locks and spinlocks +^^^^^^^^^^^^^^^^^^^ + +Locks and spinlocks are another source of blocking behavior that for the same +reasons as system calls will need to be addressed. + +If the application design ensures that the contending L-threads will always +run on the same scheduler then it its probably safe to remove locks and spin +locks completely. + +The only exception to the above rule is if for some reason the +code performs any kind of context switch whilst holding the lock +(e.g. yield, sleep, or block on a different lock, or on a condition variable). +This will need to determined before deciding to eliminate a lock. + +If a lock cannot be eliminated then an L-thread mutex can be substituted for +either kind of lock. + +An L-thread blocking on an L-thread mutex will be suspended and will cause +another ready L-thread to be resumed, thus not blocking the scheduler. When +default behavior is required, it can be used as a direct replacement for a +pthread mutex lock. + +Spin locks are typically used when lock contention is likely to be rare and +where the period during which the lock may be held is relatively short. +When the contending L-threads are running on the same scheduler then an +L-thread blocking on a spin lock will enter an infinite loop stopping the +scheduler completely (see :ref:`porting_infinite_loops` below). + +If the application design ensures that contending L-threads will always run +on different schedulers then it might be reasonable to leave a short spin lock +that rarely experiences contention in place. + +If after all considerations it appears that a spin lock can neither be +eliminated completely, replaced with an L-thread mutex, or left in place as +is, then an alternative is to loop on a flag, with a call to +``lthread_yield()`` inside the loop (n.b. if the contending L-threads might +ever run on different schedulers the flag will need to be manipulated +atomically). + +Spinning and yielding is the least preferred solution since it introduces +ready queue backlog (see also :ref:`ready_queue_backlog`). + + +.. _porting_sleeps_and_delays: + +Sleeps and delays +^^^^^^^^^^^^^^^^^ + +Yet another kind of blocking behavior (albeit momentary) are delay functions +like ``sleep()``, ``usleep()``, ``nanosleep()`` etc. All will have the +consequence of stalling the L-thread scheduler and unless the delay is very +short (e.g. a very short nanosleep) calls to these functions will need to be +eliminated. + +The simplest mitigation strategy is to use the L-thread sleep API functions, +of which two variants exist, ``lthread_sleep()`` and ``lthread_sleep_clks()``. +These functions start an rte_timer against the L-thread, suspend the L-thread +and cause another ready L-thread to be resumed. The suspended L-thread is +resumed when the rte_timer matures. + + +.. _porting_infinite_loops: + +Infinite loops +^^^^^^^^^^^^^^ + +Some applications have threads with loops that contain no inherent +rescheduling opportunity, and rely solely on the OS time slicing to share +the CPU. In a cooperative environment this will stop everything dead. These +kind of loops are not hard to identify, in a debug session you will find the +debugger is always stopping in the same loop. + +The simplest solution to this kind of problem is to insert an explicit +``lthread_yield()`` or ``lthread_sleep()`` into the loop. Another solution +might be to include the function performed by the loop into the execution path +of some other loop that does in fact yield, if this is possible. + + +.. _porting_thread_local_storage: + +Thread local storage +^^^^^^^^^^^^^^^^^^^^ + +If the application uses thread local storage, the use case should be +studied carefully. + +In a legacy pthread application either or both the ``__thread`` prefix, or the +pthread set/get specific APIs may have been used to define storage local to a +pthread. + +In some applications it may be a reasonable assumption that the data could +or in fact most likely should be placed in L-thread local storage. + +If the application (like many DPDK applications) has assumed a certain +relationship between a pthread and the CPU to which it is affinitized, there +is a risk that thread local storage may have been used to save some data items +that are correctly logically associated with the CPU, and others items which +relate to application context for the thread. Only a good understanding of the +application will reveal such cases. + +If the application requires an that an L-thread is to be able to move between +schedulers then care should be taken to separate these kinds of data, into per +lcore, and per L-thread storage. In this way a migrating thread will bring with +it the local data it needs, and pick up the new logical core specific values +from pthread local storage at its new home. + + +.. _pthread_shim: + +Pthread shim +~~~~~~~~~~~~ + +A convenient way to get something working with legacy code can be to use a +shim that adapts pthread API calls to the corresponding L-thread ones. +This approach will not mitigate any of the porting considerations mentioned +in the previous sections, but it will reduce the amount of code churn that +would otherwise been involved. It is a reasonable approach to evaluate +L-threads, before investing effort in porting to the native L-thread APIs. + + +Overview +^^^^^^^^ +The L-thread subsystem includes an example pthread shim. This is a partial +implementation but does contain the API stubs needed to get basic applications +running. There is a simple "hello world" application that demonstrates the +use of the pthread shim. + +A subtlety of working with a shim is that the application will still need +to make use of the genuine pthread library functions, at the very least in +order to create the EAL threads in which the L-thread schedulers will run. +This is the case with DPDK initialization, and exit. + +To deal with the initialization and shutdown scenarios, the shim is capable of +switching on or off its adaptor functionality, an application can control this +behavior by the calling the function ``pt_override_set()``. The default state +is disabled. + +The pthread shim uses the dynamic linker loader and saves the loaded addresses +of the genuine pthread API functions in an internal table, when the shim +functionality is enabled it performs the adaptor function, when disabled it +invokes the genuine pthread function. + +The function ``pthread_exit()`` has additional special handling. The standard +system header file pthread.h declares ``pthread_exit()`` with +``__attribute__((noreturn))`` this is an optimization that is possible because +the pthread is terminating and this enables the compiler to omit the normal +handling of stack and protection of registers since the function is not +expected to return, and in fact the thread is being destroyed. These +optimizations are applied in both the callee and the caller of the +``pthread_exit()`` function. + +In our cooperative scheduling environment this behavior is inadmissible. The +pthread is the L-thread scheduler thread, and, although an L-thread is +terminating, there must be a return to the scheduler in order that the system +can continue to run. Further, returning from a function with attribute +``noreturn`` is invalid and may result in undefined behavior. + +The solution is to redefine the ``pthread_exit`` function with a macro, +causing it to be mapped to a stub function in the shim that does not have the +``noreturn`` attribute. This macro is defined in the file +``pthread_shim.h``. The stub function is otherwise no different than any of +the other stub functions in the shim, and will switch between the real +``pthread_exit()`` function or the ``lthread_exit()`` function as +required. The only difference is that the mapping to the stub by macro +substitution. + +A consequence of this is that the file ``pthread_shim.h`` must be included in +legacy code wishing to make use of the shim. It also means that dynamic +linkage of a pre-compiled binary that did not include pthread_shim.h is not be +supported. + +Given the requirements for porting legacy code outlined in +:ref:`porting_legacy_code_to_run_on_lthreads` most applications will require at +least some minimal adjustment and recompilation to run on L-threads so +pre-compiled binaries are unlikely to be met in practice. + +In summary the shim approach adds some overhead but can be a useful tool to help +establish the feasibility of a code reuse project. It is also a fairly +straightforward task to extend the shim if necessary. + +**Note:** Bearing in mind the preceding discussions about the impact of making +blocking calls then switching the shim in and out on the fly to invoke any +pthread API this might block is something that should typically be avoided. + + +Building and running the pthread shim +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The shim example application is located in the sample application +in the performance-thread folder + +To build and run the pthread shim example + +#. Go to the example applications folder + + .. code-block:: console + + export RTE_SDK=/path/to/rte_sdk + cd ${RTE_SDK}/examples/performance-thread/pthread_shim + + +#. Set the target (a default target is used if not specified). For example: + + .. code-block:: console + + export RTE_TARGET=x86_64-native-linuxapp-gcc + + See the DPDK Getting Started Guide for possible RTE_TARGET values. + +#. Build the application: + + .. code-block:: console + + make + +#. To run the pthread_shim example + + .. code-block:: console + + lthread-pthread-shim -c core_mask -n number_of_channels + +.. _lthread_diagnostics: + +L-thread Diagnostics +~~~~~~~~~~~~~~~~~~~~ + +When debugging you must take account of the fact that the L-threads are run in +a single pthread. The current scheduler is defined by +``RTE_PER_LCORE(this_sched)``, and the current lthread is stored at +``RTE_PER_LCORE(this_sched)->current_lthread``. Thus on a breakpoint in a GDB +session the current lthread can be obtained by displaying the pthread local +variable ``per_lcore_this_sched->current_lthread``. + +Another useful diagnostic feature is the possibility to trace significant +events in the life of an L-thread, this feature is enabled by changing the +value of LTHREAD_DIAG from 0 to 1 in the file ``lthread_diag_api.h``. + +Tracing of events can be individually masked, and the mask may be programmed +at run time. An unmasked event results in a callback that provides information +about the event. The default callback simply prints trace information. The +default mask is 0 (all events off) the mask can be modified by calling the +function ``lthread_diagniostic_set_mask()``. + +It is possible register a user callback function to implement more +sophisticated diagnostic functions. +Object creation events (lthread, mutex, and condition variable) accept, and +store in the created object, a user supplied reference value returned by the +callback function. + +The lthread reference value is passed back in all subsequent event callbacks, +the mutex and APIs are provided to retrieve the reference value from +mutexes and condition variables. This enables a user to monitor, count, or +filter for specific events, on specific objects, for example to monitor for a +specific thread signaling a specific condition variable, or to monitor +on all timer events, the possibilities and combinations are endless. + +The callback function can be set by calling the function +``lthread_diagnostic_enable()`` supplying a callback function pointer and an +event mask. + +Setting ``LTHREAD_DIAG`` also enables counting of statistics about cache and +queue usage, and these statistics can be displayed by calling the function +``lthread_diag_stats_display()``. This function also performs a consistency +check on the caches and queues. The function should only be called from the +master EAL thread after all slave threads have stopped and returned to the C +main program, otherwise the consistency check will fail. diff --git a/dpdk/doc/guides/sample_app_ug/ptpclient.rst b/dpdk/doc/guides/sample_app_ug/ptpclient.rst new file mode 100644 index 0000000..53de503 --- /dev/null +++ b/dpdk/doc/guides/sample_app_ug/ptpclient.rst @@ -0,0 +1,252 @@ +..

The service cores infrastructure is part of the DPDK EAL, and allows +any DPDK component to register a service. A service is a work item or task, that +requires CPU time to perform its duty. + +This sample application registers 5 dummy services. These 5 services are used +to show how the service_cores API can be used to orchestrate these services to +run on different service lcores. This orchestration is done by calling the +service cores APIs, however the sample application introduces a "profile" +concept to contain the service mapping details. Note that the profile concept +is application specific, and not a part of the service cores API. + + +Compiling the Application +------------------------- + +#. Go to the example directory: + + .. code-block:: console + + export RTE_SDK=/path/to/rte_sdk + cd ${RTE_SDK}/examples/service_cores + +#. Set the target (a default target is used if not specified).

The ``rte_service.h`` +header file provides the functions for dynamically adding and removing cores. +The APIs to add and remove cores use lcore IDs similar to existing DPDK +functions. + +These are the functions to start a service core, and have it run a service: + +.. code-block:: c + + /* the lcore ID to use as a service core */ + uint32_t service_core_id = 7; + ret = rte_service_lcore_add(service_core_id); + if(ret) + return -1; + + /* service cores are in "stopped" state when added, so start it */ + ret = rte_service_lcore_start(service_core_id); + if(ret) + return -1; + + /* map a service to the service core, causing it to run the service */ + uint32_t service_id; /* ID of a registered service */ + uint32_t enable = 1; /* 1 maps the service, 0 unmaps */ + ret = rte_service_map_lcore_set(service_id, service_core_id, enable); + if(ret) + return -1; + + +Removing A Service Core +~~~~~~~~~~~~~~~~~~~~~~~ + +To remove a service core, the steps are similar to adding but in reverse order. +Note that it is not allowed to remove a service core if the service is running, +and the service-core is the only core running that service (see documentation +for ``rte_service_lcore_stop`` function for details). + + +Conclusion +~~~~~~~~~~ + +The service cores infrastructure provides DPDK with two main features. The first +is to abstract away hardware differences: the service core can CPU cycles to +a software fallback implementation, allowing the application to be abstracted +from the difference in HW / SW availability. The second feature is a flexible +method of registering functions to be run, allowing the running of the +functions to be scaled across multiple CPUs. diff --git a/dpdk/doc/guides/sample_app_ug/skeleton.rst b/dpdk/doc/guides/sample_app_ug/skeleton.rst new file mode 100644 index 0000000..9595617 --- /dev/null +++ b/dpdk/doc/guides/sample_app_ug/skeleton.rst @@ -0,0 +1,288 @@ +..

Example Host Application + + Using a Command Line Interface(CLI) for VM->Host communication channel management + allows adding channels to the Monitor, setting and querying the vCPU to pCPU pinning, + inspecting and manually changing the frequency for each CPU. + The CLI runs on a single lcore while the thread responsible for managing + VM requests runs on a second lcore. + + VM requests arriving on a channel for frequency changes are passed + to the librte_power ACPI cpufreq sysfs based library. + The Host Application relies on both qemu-kvm and libvirt to function. + +#. librte_power for Virtual Machines + + Using an alternate implementation for the librte_power API, requests for + frequency changes are forwarded to the host monitor rather than + the APCI cpufreq sysfs interface used on the host. + + The l3fwd-power application will use this implementation when deployed on a VM + (see :doc:`l3_forward_power_man`). + +.. _figure_vm_power_mgr_highlevel: + +.. figure:: img/vm_power_mgr_highlevel.* + + Highlevel Solution + + +Overview +-------- + +VM Power Management employs qemu-kvm to provide communications channels +between the host and VMs in the form of Virtio-Serial which appears as +a paravirtualized serial device on a VM and can be configured to use +various backends on the host. For this example each Virtio-Serial endpoint +on the host is configured as AF_UNIX file socket, supporting poll/select +and epoll for event notification. +In this example each channel endpoint on the host is monitored via +epoll for EPOLLIN events. +Each channel is specified as qemu-kvm arguments or as libvirt XML for each VM, +where each VM can have a number of channels up to a maximum of 64 per VM, +in this example each DPDK lcore on a VM has exclusive access to a channel. + +To enable frequency changes from within a VM, a request via the librte_power interface +is forwarded via Virtio-Serial to the host, each request contains the vCPU +and power command(scale up/down/min/max). +The API for host and guest librte_power is consistent across environments, +with the selection of VM or Host Implementation determined at automatically +at runtime based on the environment. + +Upon receiving a request, the host translates the vCPU to a pCPU via +the libvirt API before forwarding to the host librte_power. + +.. _figure_vm_power_mgr_vm_request_seq: + +.. figure:: img/vm_power_mgr_vm_request_seq.* + + VM request to scale frequency + + +Performance Considerations +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +While Haswell Microarchitecture allows for independent power control for each core, +earlier Microarchtectures do not offer such fine grained control. +When deployed on pre-Haswell platforms greater care must be taken in selecting +which cores are assigned to a VM, for instance a core will not scale down +until its sibling is similarly scaled. + +Configuration +------------- + +BIOS +~~~~ + +Enhanced Intel SpeedStep® Technology must be enabled in the platform BIOS +if the power management feature of DPDK is to be used. +Otherwise, the sys file folder /sys/devices/system/cpu/cpu0/cpufreq will not exist, +and the CPU frequency-based power management cannot be used. +Consult the relevant BIOS documentation to determine how these settings +can be accessed. + +Host Operating System +~~~~~~~~~~~~~~~~~~~~~ + +The Host OS must also have the *apci_cpufreq* module installed, in some cases +the *intel_pstate* driver may be the default Power Management environment. +To enable *acpi_cpufreq* and disable *intel_pstate*, add the following +to the grub Linux command line: + +.. code-block:: console + + intel_pstate=disable + +Upon rebooting, load the *acpi_cpufreq* module: + +.. code-block:: console + + modprobe acpi_cpufreq + +Hypervisor Channel Configuration +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Virtio-Serial channels are configured via libvirt XML: + + +.. code-block:: xml + + {vm_name} + +

When run with 8 threads, that is, with the -c FF option, each thread receives and forwards packets from 16 queues. + +As supplied, the sample application configures the VMDQ feature to have 32 pools with 4 queues each as indicated in :numref:`figure_vmdq_dcb_example`. +The Intel® 82599 10 Gigabit Ethernet Controller NIC also supports the splitting of traffic into 16 pools of 8 queues.

_testpmd_flow_director: + +flow_director_filter +~~~~~~~~~~~~~~~~~~~~ + +The Flow Director works in receive mode to identify specific flows or sets of flows and route them to specific queues. + +Four types of filtering are supported which are referred to as Perfect Match, Signature, Perfect-mac-vlan and +Perfect-tunnel filters, the match mode is set by the ``--pkt-filter-mode`` command-line parameter: + +* Perfect match filters. + The hardware checks a match between the masked fields of the received packets and the programmed filters. + The masked fields are for IP flow. + +* Signature filters. + The hardware checks a match between a hash-based signature of the masked fields of the received packet. + +* Perfect-mac-vlan match filters. + The hardware checks a match between the masked fields of the received packets and the programmed filters. + The masked fields are for MAC VLAN flow. + +* Perfect-tunnel match filters. + The hardware checks a match between the masked fields of the received packets and the programmed filters. + The masked fields are for tunnel flow. + +* Perfect-raw-flow-type match filters. + The hardware checks a match between the masked fields of the received packets and pre-loaded raw (template) packet. + The masked fields are specified by input sets. + +The Flow Director filters can match the different fields for different type of packet: flow type, specific input set +per flow type and the flexible payload. + +The Flow Director can also mask out parts of all of these fields so that filters +are only applied to certain fields or parts of the fields. + +Note that for raw flow type mode the source and destination fields in the +raw packet buffer need to be presented in a reversed order with respect +to the expected received packets. +For example: IP source and destination addresses or TCP/UDP/SCTP +source and destination ports + +Different NICs may have different capabilities, command show port fdir (port_id) can be used to acquire

There are available two measurement types: throughput and latency. +User can use multiply cores to run tests on but only +one type of crypto PMD can be measured during single application +execution. Cipher parameters, type of device, type of operation and +chain mode have to be specified in the command line as application +parameters. These parameters are checked using device capabilities +structure. + +Limitations +----------- +On hardware devices the cycle-count doesn't always represent the actual offload +cost. The cycle-count only represents the offload cost when the hardware +accelerator is not fully loaded, when loaded the cpu cycles freed up by the +offload are still consumed by the test tool and included in the cycle-count. +These cycles are consumed by retries and inefficient API calls enqueuing and +dequeuing smaller bursts than specified by the cmdline parameter. This results +in a larger cycle-count measurement and should not be interpreted as an offload +cost measurement. Using "pmd-cyclecount" mode will give a better idea of +actual costs of hardware acceleration. + +On hardware devices the throughput measurement is not necessarily the maximum +possible for the device, e.g. it may be necessary to use multiple cores to keep +the hardware accelerator fully loaded and so measure maximum throughput. + +Compiling the Application +------------------------- + +**Step 1: PMD setting** + +The ``dpdk-test-crypto-perf`` tool depends on crypto device drivers PMD which +are disabled by default in the build configuration file ``common_base``. +The crypto device drivers PMD which should be tested can be enabled by setting:: + + CONFIG_RTE_LIBRTE_PMD_=y + +Setting example for open ssl PMD:: + + CONFIG_RTE_LIBRTE_PMD_OPENSSL=y + +**Step 2: Linearization setting** + +It is possible linearized input segmented packets just before crypto operation +for devices which doesn't support scatter-gather, and allows to measure +performance also for this use case. + +To set on the linearization options add below definition to the +``cperf_ops.h`` file:: + + #define CPERF_LINEARIZATION_ENABLE + +**Step 3: Build the application** + +Execute the ``dpdk-setup.sh`` script to build the DPDK library together with the +``dpdk-test-crypto-perf`` applcation. + +Initially, the user must select a DPDK target to choose the correct target type +and compiler options to use when building the libraries. +The user must have all libraries, modules, updates and compilers installed +in the system prior to this, +as described in the earlier chapters in this Getting Started Guide. + +Running the Application +----------------------- + +The tool application has a number of command line options: + +.. code-block:: console + + dpdk-test-crypto-perf [EAL Options] -- [Application Options] + +EAL Options +~~~~~~~~~~~ + +The following are the EAL command-line options that can be used in conjunction +with the ``dpdk-test-crypto-perf`` applcation. +See the DPDK Getting Started Guides for more information on these options. + +* ``-c `` or ``-l `` + + Set the hexadecimal bitmask of the cores to run on.

Note:: + * The ``dpdk-pdump`` tool can only be used in conjunction with a primary + application which has the packet capture framework initialized already. + In dpdk, only the ``testpmd`` is modified to initialize packet capture + framework, other applications remain untouched.

Note:: + + * Parameters inside the parentheses represents mandatory parameters. + + * Parameters inside the square brackets represents optional parameters. + + * Multiple instances of ``--pdump`` can be passed to capture packets on different port and queue combinations. + +The ``--server-socket-path`` command line option is optional. This represents the server socket directory. +If no value is passed default values are used i.e. ``/var/run/.dpdk/`` for root users and ``~/.dpdk/`` +for non root users. + +The ``--client-socket-path`` command line option is optional. This represents the client socket directory. +If no value is passed default values are used i.e. ``/var/run/.dpdk/`` for root users and ``~/.dpdk/`` +for non root users. + + +The ``--pdump`` parameters +~~~~~~~~~~~~~~~~~~~~~~~~~~ + +``port``: +Port id of the eth device on which packets should be captured. + +``device_id``: +PCI address (or) name of the eth device on which packets should be captured. + + .. Note:: + + * As of now the ``dpdk-pdump`` tool cannot capture the packets of virtual devices + in the primary process due to a bug in the ethdev library. Due to this bug, in a multi process context, + when the primary and secondary have different ports set, then the secondary process + (here the ``dpdk-pdump`` tool) overwrites the ``rte_eth_devices[]`` entries of the primary process. + +``queue``: +Queue id of the eth device on which packets should be captured. The user can pass a queue value of ``*`` to enable +packet capture on all queues of the eth device. + +``rx-dev``: +Can be either a pcap file name or any Linux iface. + +``tx-dev``: +Can be either a pcap file name or any Linux iface. + + .. Note:: + + * To receive ingress packets only, ``rx-dev`` should be passed. + + * To receive egress packets only, ``tx-dev`` should be passed. + + * To receive ingress and egress packets separately ``rx-dev`` and ``tx-dev`` + should both be passed with the different file names or the Linux iface names. + + * To receive ingress and egress packets together, ``rx-dev`` and ``tx-dev`` + should both be passed with the same file name or the same Linux iface name. + +``ring-size``: +Size of the ring. This value is used internally for ring creation. The ring will be used to enqueue the packets from +the primary application to the secondary. This is an optional parameter with default size 16384. + +``mbuf-size``: +Size of the mbuf data. This is used internally for mempool creation. Ideally this value must be same as +the primary application's mempool's mbuf data size which is used for packet RX. This is an optional parameter with +default size 2176. + +``total-num-mbufs``: +Total number mbufs in mempool. This is used internally for mempool creation.

Layer 2 fields for + * encapsulated packets include both outer L2 header and/or inner l2 header of + * encapsulated packet. The L2 filter resource covers the following OS specific + * L2 filters. Linux/FreeBSD (per function): # Broadcast enable/disable # List + * of individual multicast filters # All multicast enable/disable filter # + * Unicast filters # Promiscuous mode VMware: # Broadcast enable/disable (per + * physical function) # All multicast enable/disable (per function) # Unicast + * filters per ring or vnic # Promiscuous mode per PF Windows: # Broadcast + * enable/disable (per physical function) # List of individual multicast filters + * (Driver needs to advertise the maximum number of filters supported) # All + * multicast enable/disable per physical function # Unicast filters per vnic # + * Promiscuous mode per PF Implementation notes on the use of VNIC in this + * command: # By default, these filters belong to default vnic for the function. + * # Once these filters are set up, only destination VNIC can be modified. # If + * the destination VNIC is not specified in this command, then the HWRM shall + * only create an l2 context id. HWRM Implementation notes for multicast + * filters: # The hwrm_filter_alloc command can be used to set up multicast + * filters (perfect match or partial match). Each individual function driver can + * set up multicast filters independently. # The HWRM needs to keep track of + * multicast filters set up by function drivers and maintain multicast group + * replication records to enable a subset of functions to receive traffic for a + * specific multicast address. # When a specific multicast filter cannot be set, + * the HWRM shall return an error. In this error case, the driver should fall + * back to using one general filter (rather than specific) for all multicast + * traffic. # When the SR-IOV is enabled, the HWRM needs to additionally track + * source knockout per multicast group record. Examples of setting unicast + * filters: For a unicast MAC based filter, one can use a combination of the + * fields and masks provided in this command to set up the filter. Below are + * some examples: # MAC + no VLAN filter: This filter is used to identify + * traffic that does not contain any VLAN tags and matches destination (or + * source) MAC address. This filter can be set up by setting only l2_addr field + * to be a valid field. All other fields are not valid. The following value is + * set for l2_addr. l2_addr = MAC # MAC + Any VLAN filter: This filter is used + * to identify traffic that carries single VLAN tag and matches (destination or + * source) MAC address.

The + * following values are set for those two valid fields. l2_addr = MAC, + * l2_ovlan_mask = 0xFFFF # MAC + no VLAN or VLAN ID=0: This filter is used to + * identify untagged traffic that does not contain any VLAN tags or a VLAN tag + * with VLAN ID = 0 and matches destination (or source) MAC address. This filter + * can be set up by setting only l2_addr and l2_ovlan fields to be valid fields. + * All other fields are not valid. The following value are set for l2_addr and + * l2_ovlan. l2_addr = MAC, l2_ovlan = 0x0 # MAC + no VLAN or any VLAN: This + * filter is used to identify traffic that contains zero or 1 VLAN tag and + * matches destination (or source) MAC address.

It should indicate an event which + * could be serious, but hasn't necessarily caused problems yet. + * + * - IXGBE_ERROR_SOFTWARE + * This category is intended for errors due to software state preventing + * something. The category is not intended for errors due to bad arguments, or + * due to unsupported features. It should be used when a state occurs which + * prevents action but is not a serious issue. + * + * - IXGBE_ERROR_ARGUMENT + * This category is for when a bad or invalid argument is passed. It should be + * used whenever a function is called and error checking has detected the + * argument is wrong or incorrect. + * + * - IXGBE_ERROR_UNSUPPORTED + * This category is for errors which are due to unsupported circumstances or + * configuration issues. It should not be used when the issue is due to an + * invalid argument, but for when something has occurred that is unsupported + * (Ex: Flow control autonegotiation or an unsupported SFP+ module.) +

Often these + * rescheduling points are provided transparently when the application + * invokes an L-thread API. + * + * In some applications it is possible that the program may enter a loop the + * exit condition for which depends on the action of another thread or a + * response from hardware. In such a case it is necessary to yield the thread + * periodically in the loop body, to allow other threads an opportunity to + * run. This can be done by inserting a call to lthread_yield() or + * lthread_sleep(n) in the body of the loop. + * + * If the application makes expensive / blocking system calls or does other + * work that would take an inordinate amount of time to complete, this will + * stall the cooperative scheduler resulting in very poor performance. + * + * In such cases an L-thread can be migrated temporarily to another scheduler + * running in a different P-thread on another core. When the expensive or + * blocking operation is completed it can be migrated back to the original + * scheduler. In this way other threads can continue to run on the original + * scheduler and will be completely unaffected by the blocking behaviour. + * To migrate an L-thread to another scheduler the API lthread_set_affinity() + * is provided. + * + * If L-threads that share data are running on the same core it is possible + * to design programs where mutual exclusion mechanisms to protect shared data + * can be avoided. This is due to the fact that the cooperative threads cannot + * preempt each other. + * + * There are two cases where mutual exclusion mechanisms are necessary. + * + * a) Where the L-threads sharing data are running on different cores. + * b) Where code must yield while updating data shared with another thread. + * + * The L-thread subsystem provides a set of mutex APIs to help with such + * scenarios, however excessive reliance on on these will impact performance + * and is best avoided if possible. + * + * L-threads can synchronise using a fast condition variable implementation + * that supports signal and broadcast. An L-thread running on any core can + * wait on a condition. + * + * L-threads can have L-thread local storage with an API modelled on either the + * P-thread get/set specific API or using PER_LTHREAD macros modelled on the + * RTE_PER_LCORE macros.

Of course, this function + * can be invoked in parallel by different logical cores on different RX queues. + * It is the responsibility of the upper level application to enforce this rule. + * + * If needed, parallel accesses by multiple logical cores to shared queues + * shall be explicitly protected by dedicated inline lock-aware functions + * built on top of their corresponding lock-free functions of the PMD API. + * + * In all functions of the Ethernet API, the Ethernet device is + * designated by an integer >= 0 named the device port identifier. + * + * At the Ethernet driver level, Ethernet devices are represented by a generic + * data structure of type *rte_eth_dev*. + * + * Ethernet devices are dynamically registered during the PCI probing phase + * performed at EAL initialization time. + * When an Ethernet device is being probed, an *rte_eth_dev* structure and + * a new port identifier are allocated for that device. Then, the eth_dev_init() + * function supplied by the Ethernet driver matching the probed PCI + * device is invoked to properly initialize the device. + * + * The role of the device init function consists of resetting the hardware, + * checking access to Non-volatile Memory (NVM), reading the MAC address + * from NVM etc. + * + * If the device init operation is successful, the correspondence between + * the port identifier assigned to the new device and its associated + * *rte_eth_dev* structure is effectively registered. + * Otherwise, both the *rte_eth_dev* structure and the port identifier are + * freed. + * + * The functions exported by the application Ethernet API to setup a device + * designated by its port identifier must be invoked in the following order: + * - rte_eth_dev_configure() + * - rte_eth_tx_queue_setup() + * - rte_eth_rx_queue_setup() + * - rte_eth_dev_start() + * + * Then, the network application can invoke, in any order, the functions + * exported by the Ethernet API to get the MAC address of a given device, to + * get the speed and the status of a device physical link, to receive/transmit + * [burst of] packets, and so on. + * + * If the application wants to change the configuration (i.e. call + * rte_eth_dev_configure(), rte_eth_tx_queue_setup(), or + * rte_eth_rx_queue_setup()), it must call rte_eth_dev_stop() first to stop the + * device and then do the reconfiguration before calling rte_eth_dev_start() + * again. The transmit and receive functions should not be invoked when the + * device is stopped. + * + * Please note that some configuration is not stored between calls to + * rte_eth_dev_stop()/rte_eth_dev_start(). The following configuration will + * be retained: + * + * - flow control settings + * - receive mode configuration (promiscuous mode, hardware checksum mode, + * RSS/VMDQ settings etc.) + * - VLAN filtering configuration + * - MAC addresses supplied to MAC address array + * - flow director filtering mode (but not filtering rules) + * - NIC queue statistics mappings + * + * Any other configuration will not be stored and will need to be re-entered + * before a call to rte_eth_dev_start(). + * + * Finally, a network application can close an Ethernet device by invoking the + * rte_eth_dev_close() function. + * + * Each function of the application Ethernet API invokes a specific function + * of the PMD that controls the target device designated by its port + * identifier. + * For this purpose, all device-specific functions of an Ethernet driver are + * supplied through a set of pointers contained in a generic structure of type + * *eth_dev_ops*. + * The address of the *eth_dev_ops* structure is stored in the *rte_eth_dev* + * structure by the device init function of the Ethernet driver, which is + * invoked during the PCI probing phase, as explained earlier. + * + * In other words, each function of the Ethernet API simply retrieves the + * *rte_eth_dev* structure associated with the device port identifier and + * performs an indirect invocation of the corresponding driver function + * supplied in the *eth_dev_ops* structure of the *rte_eth_dev* structure. + * + * For performance reasons, the address of the burst-oriented RX and TX + * functions of the Ethernet driver are not contained in the *eth_dev_ops* + * structure. Instead, they are directly stored at the beginning of the + * *rte_eth_dev* structure to avoid an extra indirect memory access during + * their invocation. + * + * RTE ethernet device drivers do not use interrupts for transmitting or + * receiving. Instead, Ethernet drivers export Poll-Mode receive and transmit + * functions to applications. + * Both receive and transmit functions are packet-burst oriented to minimize + * their cost per packet through the following optimizations: + * + * - Sharing among multiple packets the incompressible cost of the + * invocation of receive/transmit functions. + * + * - Enabling receive/transmit functions to take advantage of burst-oriented + * hardware features (L1 cache, prefetch instructions, NIC head/tail + * registers) to minimize the number of CPU cycles per packet, for instance, + * by avoiding useless read memory accesses to ring descriptors, or by + * systematically using arrays of pointers that exactly fit L1 cache line + * boundaries and sizes. + * + * The burst-oriented receive function does not provide any error notification, + * to avoid the corresponding overhead. As a hint, the upper-level application + * might check the status of the device link once being systematically returned + * a 0 value by the receive function of the driver for a given number of tries. + */ + +#ifdef __cplusplus +extern "C" { +#endif + +#include + +/* Use this macro to check if LRO API is supported */ +#define RTE_ETHDEV_HAS_LRO_SUPPORT + +#include +#include +#include +#include +#include +#include +#include +#include + +#include "rte_ether.h" +#include "rte_eth_ctrl.h" +#include "rte_dev_info.h" + +struct rte_mbuf; + +/** + * A structure used to retrieve statistics for an Ethernet port. + * Not all statistics fields in struct rte_eth_stats are supported + * by any type of network interface card (NIC).

The + * event ethernet Rx adapter provides common APIs to configure the packet flow + * from the ethernet devices to event devices across both these transfer + * mechanisms. + * + * The adapter uses a EAL service core function for SW based packet transfer + * and uses the eventdev PMD functions to configure HW based packet transfer + * between the ethernet device and the event device. + * + * The ethernet Rx event adapter's functions are: + * - rte_event_eth_rx_adapter_create_ext() + * - rte_event_eth_rx_adapter_create() + * - rte_event_eth_rx_adapter_free() + * - rte_event_eth_rx_adapter_queue_add() + * - rte_event_eth_rx_adapter_queue_del() + * - rte_event_eth_rx_adapter_start() + * - rte_event_eth_rx_adapter_stop() + * - rte_event_eth_rx_adapter_stats_get() + * - rte_event_eth_rx_adapter_stats_reset() + * + * The application creates an ethernet to event adapter using + * rte_event_eth_rx_adapter_create_ext() or rte_event_eth_rx_adapter_create() + * functions. + * The adapter needs to know which ethernet rx queues to poll for mbufs as well + * as event device parameters such as the event queue identifier, event + * priority and scheduling type that the adapter should use when constructing + * events. The rte_event_eth_rx_adapter_queue_add() function is provided for + * this purpose. + * The servicing weight parameter in the rte_event_eth_rx_adapter_queue_conf + * is applicable when the Rx adapter uses a service core function and is + * intended to provide application control of the frequency of polling ethernet + * device receive queues, for example, the application may want to poll higher + * priority queues with a higher frequency but at the same time not starve + * lower priority queues completely. If this parameter is zero and the receive + * interrupt is enabled when configuring the device, the receive queue is + * interrupt driven; else, the queue is assigned a servicing weight of one. + * + * The application can start/stop the adapter using the + * rte_event_eth_rx_adapter_start() and the rte_event_eth_rx_adapter_stop() + * functions. If the adapter uses a rte_service function, then the application + * is also required to assign a core to the service function and control the + * service core using the rte_service APIs. The + * rte_event_eth_rx_adapter_service_id_get() function can be used to retrieve + * the service function ID of the adapter in this case. + * + * Note: Interrupt driven receive queues are currently unimplemented. + */ + +#ifdef __cplusplus +extern "C" { +#endif + +#include + +#include + +#include "rte_eventdev.h" + +#define RTE_EVENT_ETH_RX_ADAPTER_MAX_INSTANCE 32 + +/* struct rte_event_eth_rx_adapter_queue_conf flags definitions */ +#define RTE_EVENT_ETH_RX_ADAPTER_QUEUE_FLOW_ID_VALID 0x1 +/**< This flag indicates the flow identifier is valid + * @see rte_event_eth_rx_adapter_queue_conf::rx_queue_flags + */ + +/** + * @warning + * @b EXPERIMENTAL: this API may change without prior notice + * + * Adapter configuration structure that the adapter configuration callback + * function is expected to fill out + * @see rte_event_eth_rx_adapter_conf_cb + */ +struct rte_event_eth_rx_adapter_conf { + uint8_t event_port_id; + /**< Event port identifier, the adapter enqueues mbuf events to this + * port. + */ + uint32_t max_nb_rx; + /**< The adapter can return early if it has processed at least + * max_nb_rx mbufs.

Each event port can be linked with one or more + * event queues for dequeue operations. + * + * By default, all the functions of the Event Device API exported by a PMD + * are lock-free functions which assume to not be invoked in parallel on + * different logical cores to work on the same target object. For instance, + * the dequeue function of a PMD cannot be invoked in parallel on two logical + * cores to operates on same event port. Of course, this function + * can be invoked in parallel by different logical cores on different ports. + * It is the responsibility of the upper level application to enforce this rule. + * + * In all functions of the Event API, the Event device is + * designated by an integer >= 0 named the device identifier *dev_id* + * + * At the Event driver level, Event devices are represented by a generic + * data structure of type *rte_event_dev*. + * + * Event devices are dynamically registered during the PCI/SoC device probing + * phase performed at EAL initialization time. + * When an Event device is being probed, a *rte_event_dev* structure and + * a new device identifier are allocated for that device. Then, the + * event_dev_init() function supplied by the Event driver matching the probed + * device is invoked to properly initialize the device. + * + * The role of the device init function consists of resetting the hardware or + * software event driver implementations. + * + * If the device init operation is successful, the correspondence between + * the device identifier assigned to the new device and its associated + * *rte_event_dev* structure is effectively registered. + * Otherwise, both the *rte_event_dev* structure and the device identifier are + * freed. + * + * The functions exported by the application Event API to setup a device + * designated by its device identifier must be invoked in the following order: + * - rte_event_dev_configure() + * - rte_event_queue_setup() + * - rte_event_port_setup() + * - rte_event_port_link() + * - rte_event_dev_start() + * + * Then, the application can invoke, in any order, the functions + * exported by the Event API to schedule events, dequeue events, enqueue events, + * change event queue(s) to event port [un]link establishment and so on. + * + * Application may use rte_event_[queue/port]_default_conf_get() to get the + * default configuration to set up an event queue or event port by + * overriding few default values. + * + * If the application wants to change the configuration (i.e. call + * rte_event_dev_configure(), rte_event_queue_setup(), or + * rte_event_port_setup()), it must call rte_event_dev_stop() first to stop the + * device and then do the reconfiguration before calling rte_event_dev_start() + * again. The schedule, enqueue and dequeue functions should not be invoked + * when the device is stopped. + * + * Finally, an application can close an Event device by invoking the + * rte_event_dev_close() function. + * + * Each function of the application Event API invokes a specific function + * of the PMD that controls the target device designated by its device + * identifier. + * + * For this purpose, all device-specific functions of an Event driver are + * supplied through a set of pointers contained in a generic structure of type + * *event_dev_ops*. + * The address of the *event_dev_ops* structure is stored in the *rte_event_dev* + * structure by the device init function of the Event driver, which is + * invoked during the PCI/SoC device probing phase, as explained earlier. + * + * In other words, each function of the Event API simply retrieves the + * *rte_event_dev* structure associated with the device identifier and + * performs an indirect invocation of the corresponding driver function + * supplied in the *event_dev_ops* structure of the *rte_event_dev* structure. + * + * For performance reasons, the address of the fast-path functions of the + * Event driver is not contained in the *event_dev_ops* structure. + * Instead, they are directly stored at the beginning of the *rte_event_dev* + * structure to avoid an extra indirect memory access during their invocation. + * + * RTE event device drivers do not use interrupts for enqueue or dequeue + * operation.

An lcore must not be + * interrupted by another task that uses the same mempool (because it uses a + * ring which is not preemptible). Also, usual mempool functions like + * rte_mempool_get() or rte_mempool_put() are designed to be called from an EAL + * thread due to the internal per-lcore cache.

A pipeline is constructed by connecting its input + * ports to its output ports through a chain of lookup tables. As result of + * lookup operation into the current table, one of the table entries (or the + * default table entry, in case of lookup miss) is identified to provide the + * actions to be executed on the current packet and the associated action + * meta-data. The behavior of user actions is defined through the configurable + * table action handler, while the reserved actions define the next hop for the + * current packet (either another table, an output port or packet drop) and are + * handled transparently by the framework. + * + * Initialization and run-time flows. Once all the pipeline elements + * (input ports, tables, output ports) have been created, input ports connected + * to tables, table action handlers configured, tables populated with the + * initial set of entries (actions and action meta-data) and input ports + * enabled, the pipeline runs automatically, pushing packets from input ports + * to tables and output ports. At each table, the identified user actions are + * being executed, resulting in action meta-data (stored in the table entry) + * and packet meta-data (stored with the packet descriptor) being updated. The + * pipeline tables can have further updates and input ports can be disabled or + * enabled later on as required. + * + * Multi-core scaling. Typically, each CPU core will run its own + * pipeline instance. Complex application-level pipelines can be implemented by + * interconnecting multiple CPU core-level pipelines in tree-like topologies, + * as the same port devices (e.g. SW rings) can serve as output ports for the + * pipeline running on CPU core A, as well as input ports for the pipeline + * running on CPU core B. This approach enables the application development + * using the pipeline (CPU cores connected serially), cluster/run-to-completion + * (CPU cores connected in parallel) or mixed (pipeline of CPU core clusters) + * programming models. + * + * Thread safety. It is possible to have multiple pipelines running on + * the same CPU core, but it is not allowed (for thread safety reasons) to have + * multiple CPU cores running the same pipeline instance. + * + ***/ + +#include + +#include +#include +#include + +struct rte_mbuf; + +/* + * Pipeline + * + */ +/** Opaque data type for pipeline */ +struct rte_pipeline; + +/** Parameters for pipeline creation */ +struct rte_pipeline_params { + /** Pipeline name */ + const char *name; + + /** CPU socket ID where memory for the pipeline and its elements (ports + and tables) should be allocated */ + int socket_id; + + /** Offset within packet meta-data to port_id to be used by action + "Send packet to output port read from packet meta-data".

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs.

By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Lesser General Public License, applies to some +specially designated software packages--typically libraries--of the +Free Software Foundation and other authors who decide to use it. You +can use it too, but we suggest you first think carefully about whether +this license or the ordinary General Public License is the better +strategy to use in any particular case, based on the explanations below. + + When we speak of free software, we are referring to freedom of use, +not price. Our General Public Licenses are designed to make sure that +you have the freedom to distribute copies of free software (and charge +for this service if you wish); that you receive source code or can get +it if you want it; that you can change the software and use pieces of +it in new free programs; and that you are informed that you can do +these things. + + To protect your rights, we need to make restrictions that forbid +distributors to deny you these rights or to ask you to surrender these +rights. These restrictions translate to certain responsibilities for +you if you distribute copies of the library or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link other code with the library, you must provide +complete object files to the recipients, so that they can relink them +with the library after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + We protect your rights with a two-step method: (1) we copyright the +library, and (2) we offer you this license, which gives you legal +permission to copy, distribute and/or modify the library. + + To protect each distributor, we want to make it very clear that +there is no warranty for the free library. Also, if the library is +modified by someone else and passed on, the recipients should know +that what they have is not the original version, so that the original +author's reputation will not be affected by problems that might be +introduced by others. + + Finally, software patents pose a constant threat to the existence of +any free program. We wish to make sure that a company cannot +effectively restrict the users of a free program by obtaining a +restrictive license from a patent holder. Therefore, we insist that +any patent license obtained for a version of the library must be +consistent with the full freedom of use specified in this license. + + Most GNU software, including some libraries, is covered by the +ordinary GNU General Public License. This license, the GNU Lesser +General Public License, applies to certain designated libraries, and +is quite different from the ordinary General Public License. We use +this license for certain libraries in order to permit linking those +libraries into non-free programs. + + When a program is linked with a library, whether statically or using +a shared library, the combination of the two is legally speaking a +combined work, a derivative of the original library. The ordinary +General Public License therefore permits such linking only if the +entire combination fits its criteria of freedom. The Lesser General +Public License permits more lax criteria for linking other code with +the library. + + We call this license the "Lesser" General Public License because it +does Less to protect the user's freedom than the ordinary General +Public License. It also provides other free software developers Less +of an advantage over competing non-free programs. These disadvantages +are the reason we use the ordinary General Public License for many +libraries. However, the Lesser license provides advantages in certain +special circumstances. + + For example, on rare occasions, there may be a special need to +encourage the widest possible use of a certain library, so that it becomes +a de-facto standard. To achieve this, non-free programs must be +allowed to use the library. A more frequent case is that a free +library does the same job as widely used non-free libraries. In this +case, there is little to gain by limiting the free library to free +software only, so we use the Lesser General Public License. + + In other cases, permission to use a particular library in non-free +programs enables a greater number of people to use a large body of +free software. For example, permission to use the GNU C Library in +non-free programs enables many more people to use the whole GNU +operating system, as well as its variant, the GNU/Linux operating +system. + + Although the Lesser General Public License is Less protective of the +users' freedom, it does ensure that the user of a program that is +linked with the Library has the freedom and the wherewithal to run +that program using a modified version of the Library. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, whereas the latter must +be combined with the library in order to run. + + GNU LESSER GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library or other +program which contains a notice placed by the copyright holder or +other authorized party saying it may be distributed under the terms of +this Lesser General Public License (also called "this License"). +Each licensee is addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also combine or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (1) uses at run time a + copy of the library already present on the user's computer system, + rather than copying library functions into the executable, and (2) + will operate properly with a modified version of the library, if + the user installs one, as long as the modified version is + interface-compatible with the version that the work was made with. + + c) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + d) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + e) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the materials to be distributed need not include anything that is +normally distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties with +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Lesser General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

However, + * it is less complex in terms of operations performed and duration, as it + * is designed to have a predictable outcome that can be tested. + * + * - A set of timers is initialized for use by the test + * - All cores then simultaneously are set to schedule all the timers at + * the same time, so conflicts should occur. + * - Then there is a delay while we wait for the timers to expire + * - Then the master lcore calls timer_manage() and we check that all + * timers have had their callbacks called exactly once - no more no less. + * - Then we repeat the process, except after setting up the timers, we have + * all cores randomly reschedule them. + * - Again we check that the expected number of callbacks has occurred when + * we call timer-manage. + * + * #. Basic test. + * + * This test performs basic functional checks of the timers. The test + * uses four different timers that are loaded and stopped under + * specific conditions in specific contexts. + * + * - Four timers are used for this test. + * - On each core, the rte_timer_manage() function is called from main loop + * every 3 microseconds. + * + * The autotest python script checks that the behavior is correct: + * + * - timer0 + * + * - At initialization, timer0 is loaded by the master core, on master core + * in "single" mode (time = 1 second). + * - In the first 19 callbacks, timer0 is reloaded on the same core, + * then, it is explicitly stopped at the 20th call. + * - At t=25s, timer0 is reloaded once by timer2. + * + * - timer1 + * + * - At initialization, timer1 is loaded by the master core, on the + * master core in "single" mode (time = 2 seconds). + * - In the first 9 callbacks, timer1 is reloaded on another + * core. After the 10th callback, timer1 is not reloaded anymore. + * + * - timer2 + * + * - At initialization, timer2 is loaded by the master core, on the + * master core in "periodical" mode (time = 1 second). + * - In the callback, when t=25s, it stops timer3 and reloads timer0 + * on the current core. + * + * - timer3 + * + * - At initialization, timer3 is loaded by the master core, on + * another core in "periodical" mode (time = 1 second). + * - It is stopped at t=25s by timer2. + */ + +#include +#include +#include +#include +#include +#include +#include +#include + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + +#define TEST_DURATION_S 1 /* in seconds */ +#define NB_TIMER 4 + +#define RTE_LOGTYPE_TESTTIMER RTE_LOGTYPE_USER3 + +static volatile uint64_t end_time;
