Commit Message

Daniel Vetter Aug. 5, 2021, 10:46 a.m. UTC 
Prep work for using the scheduler dependency handling. We need to call
drm_sched_job_init earlier so we can use the new drm_sched_job_await*
functions for dependency handling here.

v2: Slightly better commit message and rebase to include the
drm_sched_job_arm() call (Emma).

v3: Cleanup jobs under construction correctly (Emma)

v4: Rebase over perfmon patch
