feature k210 #16

masayuki2009 · 2019-12-30T13:43:17Z

Summary

Added initial support for Sipeed Maix Bit board with Kendryte K210 processor.
K210 has two RV64GC cores but in this PR only the primary core is enabled.

Impact

Some common files for RISC-V have been modified to support RV64GC.
I also checked this PR with my SparkFun RED-V Plus which has SiFive FE310 core (RV32IMAC)

Limitations / TODO

Because this is a initial porting some drivers such as GPIO/I2C/SPI are missing.
Also, nuttx (elf file) must be loaded with openocd-k210.

These limitations and TODO are described in README.txt under the board directory.

Testing

I confirmed that ostest passed. Also, basic commands such as uname/ps/free/sleep work as well.

include/stdint.h

 typedef _intptr_t           intptr_t;
 typedef _uintptr_t          uintptr_t;
+#endif



I don't believe that this is a correct change. You should not put any CPU specific definitions in the POSIX standard stdint.h. That is the wrong way to go. It violates the basic layering within the OS.

Instead, you need to change arch/risc-v/include/types.h. That is the appropriate place for this change. arch/risc-v/include/types.h defines _intptr_t and _uintptr_t and is included by include/stdint.h. This was designed this way to specifically to prohibit CPU-specific changes in stdint.h.

@patacongo Thanks for the comment. I understand what I should do. I'll fix the commits and force to push again.

@patacongo I fixed what you pointed out and pushed again.

Signed-off-by: Huang Qi <huangqi3@xiaomi.com> riscv/bl602: Implement SPI Cmd/Data To control the Data/Command Pin on ST7789 SPI Display, the SPI Driver flips the MISO Pin as though it was a GPIO. To implement this on BL602, we reconfigure MISO from SPI Pin to GPIO Pin on the fly inside `bl602_spi_cmddata()`. When the SPI Port is deselected (after the SPI operation), we revert MISO back from GPIO Pin to SPI Pin. We implement this inside `bl602_spi_select()`. [More Details Here](https://github.com/lupyuen/st7789-nuttx#spi-cmddata) This change impacts 3 LCD drivers that call `SPI_CMDDATA()`: ST7735, ST7789, GC9A01. Previously the BL602 SPI Driver would fail with "SPI cmddata not supported" when the above drivers are used. After the change, the above drivers will set the LCD Data/Command Pin correctly.

In function "wm8904_hw_reset" the priv->balance is initialized with b16HALF, indicating a range from 0 to b16ONE. In function "wm8904_setvolume" the assumed range for priv->balance is between 0 and 1000. The changes now make this consistent for 0 to b16ONE-1. Furthermore, in wm8904_configure the change of balance was not implemented. Minor fix, function name was wm8994_setvolume instead of wm8904_setvolume. Fixed source code format errors.

Currently the implementation of up_cpu_index is done a bit lazily, because it assumes hartid == cpu index, but this is not 100% accurate, so it is still missing some logic. arch/risc-v/riscv_misaligned: Correct sw source register If source register of sw instruction is x0, we must point it to a constant zero since in NuttX's context, value of index 0 is EPC.

The current implementation of env_dup does precisely this and thus, it fails at once when it is attempted between two user processes. The solution is to use the kernel's heap as an intermediate buffer. This is a simple, effective and common way to do a fork(). Obviously this is not needed for kernel processes. syscall: Add call gate for get_environ_ptr Now that the environment strings are stored as an array of strings, they can be passed from the application via char **environ, which is really defined as a function call to get_environ_ptr(). This works as is for flat build, but protected mode and kernel mode require a call gate, which is added here. binfmt_execmodule: If incoming envp is NULL get parent envp This keeps backwards compatibility with apps that do not provide envp. The old implementation passes NULL always and this change fixes any regression caused by it. assert: static_assert is not support in c standard C89,C99.
