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
v4: Updated kerneldocs, removed unused funct, properly allocate
balloning nodes if non existent, removed inline keywords, enums for
offsets in CTB messages, less error messages, if return unused then
made functs void
v5: Removed drm_mm change, but added VF init modifications. These then
allowed to re-use ballooning functions during ggtt node fixing.
v6: Minor update - fixed some misplaced funct declarations
Tomasz Lis (4):
drm/xe/vf: Divide ballooning into allocation and insertion
drm/xe/sriov: Shifting GGTT area post migration
drm/xe/guc: Introduce enum with offsets for multi-LRC register H2G
drm/xe/vf: Fixup CTB send buffer messages after migration
