[PATCH 6/7] drm/amdgpu: move UVD IB test into common code v2

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

 



From: Christian König <christian.koenig@xxxxxxx>

Since we now raise the clocks from begin_use() we don't need
a separate function for each hw generation any more.

v2: remove unintentional lowering of the UVD clocks, fix typos for CIK hw.
