Subject: drm/amdgpu: unify MQD programming sequence for kfd and amdgpu v2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 97bf47b21d593c92d8c89be159afccb5d6562279
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
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
