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. v2: Switcghed to update of addresses by xe_lrc_write_ctx_reg() to avoid kzalloc(), renamed or moved few functions 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 drivers/gpu/drm/xe/xe_exec_queue.c | 27 +++++++ drivers/gpu/drm/xe/xe_exec_queue.h | 4 + drivers/gpu/drm/xe/xe_gpu_scheduler.c | 13 ++++ drivers/gpu/drm/xe/xe_gpu_scheduler.h | 1 + drivers/gpu/drm/xe/xe_gt_debugfs.c | 3 +- drivers/gpu/drm/xe/xe_gt_sriov_vf.c | 10 +++ drivers/gpu/drm/xe/xe_guc_buf.c | 2 +- drivers/gpu/drm/xe/xe_guc_submit.c | 91 +++++++++++++++++++++- drivers/gpu/drm/xe/xe_guc_submit.h | 8 ++ drivers/gpu/drm/xe/xe_lrc.c | 51 +++++++++++++ drivers/gpu/drm/xe/xe_lrc.h | 3 + drivers/gpu/drm/xe/xe_sa.c | 1 - drivers/gpu/drm/xe/xe_sa.h | 15 +++- drivers/gpu/drm/xe/xe_sa_types.h | 1 - drivers/gpu/drm/xe/xe_sriov_vf.c | 105 +++++++++++++++++++++++++- drivers/gpu/drm/xe/xe_sriov_vf.h | 1 + 16 files changed, 327 insertions(+), 9 deletions(-) -- 2.25.1
