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 xe_lrc structs within queues
* for fixing xe_job structs and the commands they emit
It also provides some performance and stability fixes - blocking
submissions and resets while the fixups are being applied.
In case of sub-allocator, it removes the cached GGTT addresses
instead of implementing fixups for them.
Tomasz Lis (7):
drm/xe/sa: Avoid caching GGTT address within the manager
drm/xe/vf: Finish RESFIX by reset if CTB not enabled
drm/xe/vf: Pause submissions during RESFIX fixups
drm/xe: Block reset while recovering from VF migration
drm/xe/vf: Rebase HWSP of all contexts after migration
drm/xe/vf: Rebase MEMIRQ structures for all contexts after migration
drm/xe/vf: Post migration, repopulate ring area for pending request
