[PATCH v1 0/4] 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 most of 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.


Tomasz Lis (4):
  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
