[PATCH] drm/amdgpu: move UVD and VCE sched entity init after sched init

Alex Deucher alexander.deucher at amd.com
Wed Nov 8 18:41:51 UTC 2023


We need kernel scheduling entities to deal with handle clean up
if apps are not cleaned up properly.  With commit 56e449603f0ac5
("drm/sched: Convert the GPU scheduler to variable number of run-queues")
the scheduler entities have to be created after scheduler init, so
change the ordering to fix this.

v2: Leave logic in UVD and VCE code

Fixes: 56e449603f0ac5 ("drm/sched: Convert the GPU scheduler to variable number of run-queues")
