[PATCH] drm/amdgpu: tighten gpu_recover in mailbox_flr to avoid duplicate recover in sriov

2019-01-29 Thread wentalou
sriov's gpu_recover inside xgpu_ai_mailbox_flr_work would cause duplicate 
recover in TDR.
TDR's gpu_recover would be triggered by amdgpu_job_timedout,
that could avoid vk-cts failure by unexpected recover.

So if I understand correctly your goal is to avoid the gpu recover 
triggered from xgpu_ai_mailbox_flr_work, bot I don't understand how 
adding 'amdgpu_lockup_timeout == 0' achieves that ?

Yes amdgpu_lockup_timeout was forced to 1 in current code, that means 
amdgpu_device_gpu_recover was not triggered inside xgpu_ai_mailbox_flr_work.
For sriov, amdgpu_device_gpu_recover was already called by amdgpu_job_timedout, 
unexpected amdgpu_device_gpu_recover called by xgpu_ai_mailbox_flr_work would 
make vk-cts failed.

Not sure I fully understand the intent here but amdgpu_lockup_timeout == 0 is 
forced to 1 in amdgpu_device_check_arguments and hence not an indication of 
disabled gpu recover - it will still happen.
