[PATCH v3 0/3] drm/xe/vf: Post-migration recovery of GGTT nodes and CTB

[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 adds two fixup functions to the recovery worker:
* for fixing drm_mm nodes which represent GGTT allocations
* for fixing content of outgoing CTB buffer

v2: Fixed missing include, made checkpatch happy
v3: Moved some functs to xe_ggtt.c; moved shift computation to just
  after querying; improved documentation; switched some warns to asserts;
  skipping fixups when GGTT shift eq 0; iterating through tiles rather
  than gts; fixes in log messages

Tomasz Lis (3):
  drm/drm_mm: Safe macro for iterating through nodes in range
  drm/xe/sriov: Shifting GGTT area post migration
  drm/xe/vf: Fixup CTB send buffer messages after migration
