Subject: drm/amdgpu: add helper function to initialize mqd from ring v4
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 80af9daa62faeb9397a80ddf5777f97809efb166
Patch-mainline: v5.19-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225

Add the helper function to initialize mqd from ring configuration.

v2: use if/else pair instead of ?/: pair
v3: use simpler way to judge hqd_active
v4: fix parameters to amdgpu_gfx_is_high_priority_compute_queue
