drm_sched_entity_flush() should be called from the flush callback from
the file_operations structure of panfrost. See amdgpu_flush() and
amdgpu_ctx_mgr_entity_flush(). This makes sure that we wait for all
entities of the process/file descriptor to be flushed out.
drm_sched_entity_fini() must be called before you free the memory the
entity structure or otherwise we would run into an use after free.
Right, drm_sched_entity_destroy() invokes these two functions and
Panfrost uses drm_sched_entity_destroy().
Than I have no idea what's going wrong here.
The scheduler should trivially finish with the entity and call
complete(&entity->entity_idle) in it's main loop. No idea why this
doesn't happen. Can you investigate?
