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. v2: renamed and moved functions, updated logged messages, removed unused includes, used anon struct, keeping pm ref during whole recovery, skip handshake, style fixes (Michal) v3: ordering, kerneldoc, asserts, debug messages, on_all_tiles -> on_all_gts, switched 'err' and 'ret' (Michal) 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 provisinoning query drm/xe/vf: Defer fixups if migrated twice fast drivers/gpu/drm/xe/Makefile | 3 +- .../gpu/drm/xe/abi/guc_actions_sriov_abi.h | 38 +++++ drivers/gpu/drm/xe/xe_device_types.h | 2 + drivers/gpu/drm/xe/xe_gt_sriov_vf.c | 56 ++++++ drivers/gpu/drm/xe/xe_gt_sriov_vf.h | 2 + drivers/gpu/drm/xe/xe_guc.c | 14 +- drivers/gpu/drm/xe/xe_memirq.c | 3 + drivers/gpu/drm/xe/xe_sriov.c | 4 + drivers/gpu/drm/xe/xe_sriov_types.h | 16 ++ drivers/gpu/drm/xe/xe_sriov_vf.c | 160 ++++++++++++++++++ drivers/gpu/drm/xe/xe_sriov_vf.h | 14 ++ 11 files changed, 310 insertions(+), 2 deletions(-) create mode 100644 drivers/gpu/drm/xe/xe_sriov_vf.c create mode 100644 drivers/gpu/drm/xe/xe_sriov_vf.h -- 2.25.1
