Bas Nieuwenhuizen 1decbf6bb0 drm/sched: Fix entities with 0 rqs. ... Some blocks in amdgpu can have 0 rqs. Job creation already fails with -ENOENT when entity->rq is NULL, so jobs cannot be pushed. Without a rq there is no scheduler to pop jobs, and rq selection already does the right thing with a list of length 0. So the operations we need to fix are: - Creation, do not set rq to rq_list[0] if the list can have length 0. - Do not flush any jobs when there is no rq. - On entity destruction handle the rq = NULL case. - on set_priority, do not try to change the rq if it is NULL.
