[PATCH v4 0/4] drm/xe/vf: Post-migration recovery worker basis

[Tomasz Lis]

To support VF Migration, it is necessary to do fixups to any
non-virtualized resources. These fixups need to be applied within
VM, on the KMD working with VF.

This series introduces a post-migration recovery worker, executed
after migration to perform fixups.

Specific fixups will be added later in further series.

v2: renamed and moved functions, updated logged messages, removed
  unused includes, used anon struct, keeping pm ref during whole
  recovery, skip handshake, style fixes (Michal)
v3: ordering, kerneldoc, asserts, debug messages, on_all_tiles ->
  on_all_gts, switched 'err' and 'ret'  (Michal)
v4: fixed missing header include in one patch

Tomasz Lis (4):
  drm/xe/vf: React to MIGRATED interrupt
  drm/xe/vf: Send RESFIX_DONE message at end of VF restore
  drm/xe/vf: Start post-migration fixups with provisinoning query
  drm/xe/vf: Defer fixups if migrated twice fast
