[PATCH] drm/amdgpu: no job timeout setting on compute queues

[Liu, Monk]

Besides, if some compute shader takes time more them 50 seconds, you can just set lockuptime out to 50s
Why change the logic in kmd side ?

I don’t think it’s a good idea to disable the time out message for compute ring, we have virtualization end-user
Still want those message printed out

Can you do this way ?
In amdgpu_job_timeout, you can use DRM_WARN to replace DRM_ERROR for the job belongs to CPC engine ?

That’s fine for me. Will update the patch accordingly.

How about something like this:

/* Disable timeout when GPU reset is disabled to avoid confusing timeout messages in the kernel log */

If (amdgpu_gpu_recovery == 0 || amdgpu_gpu_recovery == -1)

    amdgpu_lockup_timeout = MAX_SCHEDULE_TIMEOUT;

Wouldn't that be rather surprising for somebody who sets
amdgpu.gpu_recovery=1 ?
