[PATCH 2/2] drm/amdgpu:Always save uvd vcpu_bo in VM Mode

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

 



When UVD is in VM mode, there is not uvd handle exchanged,
uvd.handles are always 0. So vcpu_bo always need save,
Otherwise amdgpu driver will fail during suspend/resume.
