[PATCH v3 0/5] drm/xe: Allow migrate vm gpu submissions from reclaim context

[Thomas Hellström]

On lunar lake, we need to be able to copy CCS compression metadata from
reclaim context when using a shrinker.
ince we do dma_fence allocations under the
struct xe_migrate::job_mutex, we're facing a lockdep violation.
This patchset deals with moving the job + fence allocation out of
the job_mutex by splitting up the fence allocation- and
initialization.

v2:
- Add a patch from Matthew Brost to fix up the use of
  composite fence seqno.
- A couple of bugfixes as detailed in patch 3.
v3:
- Rebase on drm-tip.

Matthew Brost (1):
  drm/xe: Decouple job seqno and lrc seqno

Thomas Hellström (4):
  drm/xe: Split lrc seqno fence creation up
  drm/xe: Don't initialize fences at xe_sched_job_create()
  drm/xe: Remove xe_lrc_create_seqno_fence()
  drm/xe: Move job creation out of the struct xe_migrate::job_mutex
