[PATCH 0/4] 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.

However since 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.

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
