[PATCH 05/17] drm/amdgpu: unify MQD programming sequence for kfd and amdgpu v2

Andres Rodriguez andresx7 at gmail.com
Thu Apr 13 21:35:30 UTC 2017


Use the same gfx_*_mqd_commit function for kfd and amdgpu codepaths.

This removes the last duplicates of this programming sequence.

v2: fix cp_hqd_pq_wptr value
