[PATCH v3 00/13] DRM scheduler changes for Xe

[Matthew Brost]

As a prerequisite to merging the new Intel Xe DRM driver [1] [2], we
have been asked to merge our common DRM scheduler patches first.

This a continuation of a RFC [3] with all comments addressed, ready for
a full review, and hopefully in state which can merged in the near
future. More details of this series can found in the cover letter of the
RFC [3].

These changes have been tested with the Xe driver.

v2:
 - Break run job, free job, and process message in own work items
 - This might break other drivers as run job and free job now can run in
   parallel, can fix up if needed

v3:
 - Include missing patch 'drm/sched: Add drm_sched_submit_* helpers'
 - Fix issue with setting timestamp to early
 - Don't dequeue jobs for single entity after calling entity fini
 - Flush pending jobs on entity fini
 - Add documentation for entity teardown
 - Add Matthew Brost to maintainers of DRM scheduler
