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
v4:
- Drop message interface
- Drop 'Flush pending jobs on entity fini'
- Drop 'Add documentation for entity teardown'
- Address all feedback
