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; sent to a different list by mistake: https://patchwork.freedesktop.org/series/146977/#rev2 v7: Altered, rephrased, added or promoted several kerneldocs; added _locked versions of some functs; improved lockdep tagging; altered error handling; renamed or moved some functions; defined few macros; prepared CTB fixups for future changes of CTB handling; renamed and introduced enums; did many minor changes to adjust for xe-specific coding practices v8: renamed several functions, reused helpers, separated switch cases, documented more functs, shortened asserts, added `_locked` suffixes, fixed a leak in error path v9: More helpers, fixed coding style, renamed and moved functions, improved kerneldoc, added asserts, avoided null dereference v10: More xe_map*() functs to macros, added asserts and debug print, changed params of two functions v11: Errors in place of some asserts, printing ggtt shift via debugfs, minor style fixes v12: Fixed invalid conditionals in CTB fixups Tomasz Lis (4): drm/xe/vf: Divide GGTT ballooning into allocation and insertion drm/xe/vf: Shifting GGTT area post migration drm/xe/guc: Introduce enum with offsets for context register H2Gs drm/xe/vf: Fixup CTB send buffer messages after migration drivers/gpu/drm/xe/abi/guc_actions_abi.h | 31 +++ drivers/gpu/drm/xe/xe_ggtt.c | 83 ++++++-- drivers/gpu/drm/xe/xe_ggtt.h | 7 +- drivers/gpu/drm/xe/xe_gt_sriov_vf.c | 218 +++++++++++++++++++--- drivers/gpu/drm/xe/xe_gt_sriov_vf.h | 4 + drivers/gpu/drm/xe/xe_gt_sriov_vf_types.h | 2 + drivers/gpu/drm/xe/xe_guc_ct.c | 183 ++++++++++++++++++ drivers/gpu/drm/xe/xe_guc_ct.h | 2 + drivers/gpu/drm/xe/xe_guc_submit.c | 17 ++ drivers/gpu/drm/xe/xe_map.h | 18 ++ drivers/gpu/drm/xe/xe_sriov_vf.c | 40 ++++ 11 files changed, 556 insertions(+), 49 deletions(-) -- 2.25.1
