Xiangliang,
the comments of yours is a little inappropriate, please change the comments to something like:
amdgpu_gpu_reset() only works on bare-metal case and for SRIOV many inside it need re-work to adapt to VF device
so currently just don't do it.

主�: [V2 11/11] drm/amdgpu: do not reset gpu for virtualization
Current job timeout setting is not fit for virtualization, so it
will cause job timeout sometimes. Add workaround for this when
timeout happen.
