After commit f6ebbcf ("cpufreq: intel_pstate: Implement passive mode with HWP enabled") it is possible to change the driver status to "off" via sysfs with HWP enabled, which effectively causes the driver to unregister itself, but HWP remains active and it forces the minimum performance, so even if another cpufreq driver is loaded, it will not be able to control the CPU frequency. For this reason, make the driver refuse to change the status to "off" with HWP enabled. Signed-off-by: Rafael J.

Make intel_pstate update the cached EPP value when setting the EPP via sysfs in the active mode just like it is the case in the passive mode, for consistency, but also for the benefit of subsequent changes.

Modify the EPP sysfs interface to reject attempts to change the EPP
to values different from 0 ("performance") in the active mode with
the "performance" policy (ie. scaling_governor set to "performance"),
to avoid situations in which the kernel appears to discard data
passed to it via the EPP sysfs attribute.

Add ->offline and ->online driver callbacks to prepare for taking a CPU offline and to restore its working configuration when it goes back online, respectively, to avoid invoking the ->init callback on every CPU online which is quite a bit of unnecessary overhead. Define ->offline and ->online so that they can be used in the passive mode as well as in the active mode and because ->offline will do the majority of ->stop_cpu work, the passive mode does not need that callback any more, so drop it from there. Also modify the active mode ->suspend and ->resume callbacks to prevent them from interfering with the new ->offline and ->online ones in case the latter are invoked withing the system-wide suspend and resume code flow and make the passive mode use them too.

When intel_pstate switches the operation mode from "active" to "passive" or the other way around, freeing its data structures representing CPUs and allocating them again from scratch is not necessary and wasteful. Moreover, if these data structures are preserved, the cached HWP Request MSR value from there may be written to the MSR to start with to reinitialize it and help to restore the EPP value set previously (it is set to 0xFF when CPUs go offline to allow their SMT siblings to use the full range of EPP values and that also happens when the driver gets unregistered). Accordingly, modify the driver to only do a full cleanup on driver object registration errors and when its status is changed to "off" via sysfs and to write the cached HWP Request MSR value back to the MSR on CPU init if the data structure representing the given CPU is still there.

This fixes the behavior of the scaling_max_freq and scaling_min_freq sysfs files in systems which had turbo disabled by the BIOS. Caleb noticed that the HWP is programmed to operate in the wrong P-state range on his system when the CPUFREQ policy min/max frequency is set via sysfs. This seems to be because in his system intel_pstate_get_hwp_max() is returning the maximum turbo P-state even though turbo was disabled by the BIOS, which causes intel_pstate to scale kHz frequencies incorrectly e.g. setting the maximum turbo frequency whenever the maximum guaranteed frequency is requested via sysfs.

Commit 935fcc5 ("dm mpath: only flush workqueue when needed") changed flush_multipath_work() to avoid needless workqueue flushing (of a multipath global workqueue). But that change didn't realize the surrounding flush_multipath_work() code should also only run if 'pg_init_in_progress' is set. Fix this by only doing all of flush_multipath_work()'s PG init related work if 'pg_init_in_progress' is set. Otherwise multipath_wait_for_pg_init_completion() will run unconditionally but the preceeding flush_workqueue(kmpath_handlerd) may not. This could lead to deadlock (though only if kmpath_handlerd never runs a corresponding work to decrement 'pg_init_in_progress'). It could also be, though highly unlikely, that the kmpath_handlerd work that does PG init completes before 'pg_init_in_progress' is set, and then an intervening DM table reload's multipath_postsuspend() triggers flush_multipath_work().

…IC_FTRACE In the arm64 module linker script, the section .text.ftrace_trampoline is specified unconditionally regardless of whether CONFIG_DYNAMIC_FTRACE is enabled (this is simply due to the limitation that module linker scripts are not preprocessed like the vmlinux one). Normally, for .plt and .text.ftrace_trampoline, the section flags present in the module binary wouldn't matter since module_frob_arch_sections() would assign them manually anyway. However, the arm64 module loader only sets the section flags for .text.ftrace_trampoline when CONFIG_DYNAMIC_FTRACE=y. That's only become problematic recently due to a recent change in binutils-2.35, where the .text.ftrace_trampoline section (along with the .plt section) is now marked writable and executable (WAX). We no longer allow writable and executable sections to be loaded due to commit 5c3a7db ("module: Harden STRICT_MODULE_RWX"), so this is causing all modules linked with binutils-2.35 to be rejected under arm64. Drop the IS_ENABLED(CONFIG_DYNAMIC_FTRACE) check in module_frob_arch_sections() so that the section flags for .text.ftrace_trampoline get properly set to SHF_EXECINSTR|SHF_ALLOC, without SHF_WRITE.

In practice, the bug this warning appears to be concerned with would not
actually matter because ret gets initialized to the return value of
cnl_verify_procmon_ref_values. However, that does appear to be a bug
since it means the first hunk of the patch this fixes won't actually do
anything (since the values of check_phy_reg won't factor into the final
ret value). Initialize ret to true then make all of the assignments a
bitwise AND with itself so that the function always does what it should
do.

This patch fixes a few bugs: 1- We weren't taking into account sha_leftovers when adding multiple ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with the beginning of ksv[j] 2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was being placed on the wrong half of sha_text, overlapping the leftover ksv value 3- In the sha_leftovers == 2 case, we need to manually terminate the byte stream with 0x80 since the hardware doesn't have enough room to add it after writing M0 The upside is that all of the HDCP supported HDMI repeaters I could find on Amazon just strip HDCP anyways, so it turns out to be _really_ hard to hit any of these cases without an MST hub, which is not (yet) supported.

Examples for this are auxiliary devices such as analog amplifiers

The ASoC core provides a way to probe these components by adding
them to snd_soc_card->aux_dev. We can use the snd_soc_of_parse_aux_devs()
function to parse them from the device tree.
As an example for this, some MSM8916 smartphones have an analog
speaker amplifier connected to the HPHR output. With the new property
this can be modelled as follows:
speaker-amp: audio-amplifier {
compatible = "simple-audio-amplifier";
enable-gpios = <&msmgpio 114 GPIO_ACTIVE_HIGH>;
sound-name-prefix = "Speaker Amp";
};

…ce alerts In system suspend stress cases, the SOF CI reports timeouts. The root cause is that an alert is generated while the system suspends. The interrupt handling generates transactions on the bus that will never be handled because the interrupts are disabled in parallel. As a result, the transaction never completes and times out on resume. This error doesn't seem too problematic since it happens in a work queue, and the system recovers without issues. Nevertheless, this race condition should not happen. When doing a system suspend, or when disabling interrupts, we should make sure the current transaction can complete, and prevent new work from being queued.
