[PATCH] drm/amd/powerplay: increase the SMU msg response waiting time

[PATCH] drm/amd/powerplay: increase the SMU msg response waiting time

[Evan Quan]

Increase the waiting time to 1s from 200ms. This is expected
to fix some mode1 reset failures.

If this is just for the SMU, maybe it would be better to add a separate timeout for the SMU since this will increase the timeout for lots of things, unless we need an overall timeout increase for mode1 reset.

RE: [PATCH] drm/amd/powerplay: increase the SMU msg response waiting time

Hi Alex,

There are actually two MAX_USEC_TIMEOUT related macros.
AMD_MAX_USEC_TIMEOUT is used for SMU and AMDGPU_MAX_USEC_TIMEOUT is used widely in other parts.
Maybe you mistreated it as  AMDGPU_MAX_USEC_TIMEOUT. I was confused by them too.

drivers/gpu/drm/amd/include/amd_shared.h:29:#define AMD_MAX_USEC_TIMEOUT                200000  /* 200 ms */
drivers/gpu/drm/amd/amdgpu/amdgpu.h:179:#define AMDGPU_MAX_USEC_TIMEOUT                 100000  /* 100 ms */

I'm considering to sort these timeout settings up later. Maybe to combine them as one or give them differentiated names.

Regards,
Evan

Indeed.  I was mixing them up.  We should clarify those.  Patch is:
