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

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

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.

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 GuC MMIO handshake
  drm/xe/vf: Defer fixups if migrated twice fast
