[PATCH 0/6] PF: Initial support to save/restore VF GuC state

[Michal Wajdeczko]

To successfully migrate a VM with attached GPU VF we also need to
migrate VF's GuC state. This series adds necessary functions to save
and restore a VF state and also allows testing migration flow using
debugfs, ahead of availability of other required components that are
under development.

Michal Wajdeczko (6):
  drm/xe/guc: Fix GUC_{SUBMIT,FIRMWARE}_VER helper macros
  drm/xe/guc: Add PF2GUC_SAVE_RESTORE_VF to ABI
  drm/xe/pf: Add functions to save and restore VF GuC state
  drm/xe/pf: Save VF GuC state when pausing VF
  drm/xe/pf: Allow to view and replace VF GuC state over debugfs
  drm/xe/pf: Allow to trigger VF GuC state restore from debugfs
