[PATCH v2 0/5] drm/xe/vf: Fix exec queue creation during post-migration recovery

[Tomasz Lis <tomasz.lis@intel.com>]

Fix a few issues which sporadically happen due to a race between
post-migration fixups procedure, and exec queue creation routine.

Tests which create a lot of exec queues were sporadically failing
due to one of LRCs having its state within VRAM damaged. This series
fixes all such issues, by prolonging wait for fixups within EQ
creation, and also re-creating the one LRC whose creation happened
at the time of VF switch.

v2: Add a patch with atomic value increase which allowed to solve the
  few very rare test fails which were still happening.

Tomasz Lis (5):
  drm/xe/queue: Call fini on exec queue creation fail
  drm/xe/vf: Avoid LRC being freed while applying fixups
  drm/xe/vf: Wait for default LRCs fixups before using
  drm/xe/vf: Redo LRC creation while in VF fixups
  drm/xe/vf: Use marker to catch fixups during LRC creation
