The simple_strtol() function is deprecated. kstrto[l,u32]() is the correct replacement as it can properly handle overflows. This patch replaces the deprecated simple_strtol() use introduced recently. As clk is of type uint32_t, we are safe to use kstrtou32(). It is also safe to return zero on string parsing error, similar to the case of returning zero if buf is empty in parse_clk().

Extend the comment to mention the CAP_SYS_NICE or DRM_MASTER requirement is only applicable with the former.

Apply the same setting to SH_MEM_CONFIG and VM_CONTEXT1_CNTL. This makes the noretry param no longer KFD-specific. On GFX10 I'm not changing SH_MEM_CONFIG in this commit because GFX10 has different retry behaviour in the SQ and I don't have a way to test it at the moment. Suggested-by:

[Why] The drm_audio_component can be used to give pin ELD notifications directly to the sound driver. This fixes audio endpoints disappearing due to missing unsolicited notifications. [How] Send the notification via the audio component whenever we enable or disable audio state on a stream. This matches what i915 does with their drm_audio_component and what Takashi Iwai's proposed hack for radeon/amdpgu did. This is a bit delayed in when the notification actually occurs, however. We wait until after all the programming is complete rather than sending the notification mid sequence. Particular care is needed for the get ELD callback since it can happen outside the locking and fencing DRM does for atomic commits.

[Why] In order to give pin notifications to the sound driver from DM we need to know whether audio is enabled on a stream and what pin it's using from DC. [How] Expose the instance via stream status if it's a mapped resource for the stream. It will be -1 if there's no audio mapped.

This RELEASE_MEM use has the Release semantic, which means we should write back but not invalidate. Invalidations only make sense with the Acquire semantic (ACQUIRE_MEM), or when RELEASE_MEM is used to do the combined Acquire-Release semantic, which is a barrier, not a fence. The undesirable side effect of doing invalidations for the Release semantic is that it invalidates caches while shaders are running, because the Release can execute in the middle of the next IB. UMDs should use ACQUIRE_MEM at the beginning of IBs. Doing cache invalidations for a fence (like in this case) doesn't do anything for correctness. Signed-off-by:
