[PATCH] drm/amdgpu: Add an extra evict_resource call during device_suspend.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



- evict_resource is taking too long causing sriov full access mode timeout.
  So, add an extra evict_resource in the beginning as an early evict.
