[PATCH 2/2] drm/amdgpu: cleanup VCN IB generation

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

 



Tested with latest amd-staging-drm-next + VCN patch on top. VCN dec 
tests pass but when modprobing amdgpu I get a few warnings and BUG_ONs - 
log attached. UVD is not enabled so can't test the UVD patch.


Thanks,

Andrey
