This is the implemenation for both GuC and execlists. In addition to selftests in the series, an IGT is available implemented in the first 4 patches [2]. The execbuf IOCTL changes have been done in a single large patch (#21) as all the changes flow together and I believe a single patch will be better if some one has to lookup this change in the future. Can split in a series of smaller patches if desired. This code is available in a public [3] repo for UMD teams to test there code on. v2: Drop complicated state machine to block in kernel if no guc_ids available, perma-pin parallel contexts, reworker execbuf IOCTL to be a series of loops inside the IOCTL rather than 1 large one on the outside, address Daniel Vetter's comments v3: Address John Harrison's comments, add a couple of patches which fix bugs found internally v4: Address John Harrison's latest round of comments Signed-off-by: Matthew Brost [1] https://patchwork.freedesktop.org/series/92028/ [2] https://patchwork.freedesktop.org/series/93071/ [3] https://gitlab.freedesktop.org/mbrost/mbrost-drm-intel/-/tree/drm-intel-parallel Matthew Brost (25): drm/i915/guc: Move GuC guc_id allocation under submission state sub-struct drm/i915/guc: Take GT PM ref when deregistering context drm/i915/guc: Take engine PM when a context is pinned with GuC submission drm/i915/guc: Don't call switch_to_kernel_context with GuC submission drm/i915: Add logical engine mapping drm/i915: Expose logical engine instance to user drm/i915/guc: Introduce context parent-child relationship drm/i915/guc: Add multi-lrc context registration drm/i915/guc: Ensure GuC schedule operations do not operate on child contexts drm/i915/guc: Assign contexts in parent-child relationship consecutive guc_ids drm/i915/guc: Implement parallel context pin / unpin functions drm/i915/guc: Implement multi-lrc submission drm/i915/guc: Insert submit fences between requests in parent-child relationship drm/i915/guc: Implement multi-lrc reset drm/i915/guc: Update debugfs for GuC multi-lrc drm/i915/guc: Connect UAPI to GuC multi-lrc interface drm/i915/doc: Update parallel submit doc to point to i915_drm.h drm/i915/guc: Add basic GuC multi-lrc selftest drm/i915/guc: Implement no mid batch preemption for multi-lrc drm/i915: Multi-BB execbuf drm/i915/guc: Handle errors in multi-lrc requests drm/i915: Make request conflict tracking understand parallel submits drm/i915: Update I915_GEM_BUSY IOCTL to understand composite fences drm/i915: Enable multi-bb execbuf drm/i915/execlists: Weak parallel submission support for execlists Documentation/gpu/rfc/i915_parallel_execbuf.h | 122 -- Documentation/gpu/rfc/i915_scheduler.rst | 4 +- drivers/gpu/drm/i915/gem/i915_gem_busy.c | 57 +- drivers/gpu/drm/i915/gem/i915_gem_context.c | 227 ++- .../gpu/drm/i915/gem/i915_gem_context_types.h | 16 +- .../gpu/drm/i915/gem/i915_gem_execbuffer.c | 786 ++++++--- drivers/gpu/drm/i915/gt/intel_context.c | 50 +- drivers/gpu/drm/i915/gt/intel_context.h | 54 +- drivers/gpu/drm/i915/gt/intel_context_types.h | 73 +- drivers/gpu/drm/i915/gt/intel_engine.h | 12 +- drivers/gpu/drm/i915/gt/intel_engine_cs.c | 66 +- drivers/gpu/drm/i915/gt/intel_engine_pm.c | 13 + drivers/gpu/drm/i915/gt/intel_engine_pm.h | 37 + drivers/gpu/drm/i915/gt/intel_engine_types.h | 7 + .../drm/i915/gt/intel_execlists_submission.c | 63 +- drivers/gpu/drm/i915/gt/intel_gt_pm.h | 14 + drivers/gpu/drm/i915/gt/intel_lrc.c | 7 + drivers/gpu/drm/i915/gt/selftest_execlists.c | 12 +- .../gpu/drm/i915/gt/uc/abi/guc_actions_abi.h | 1 + drivers/gpu/drm/i915/gt/uc/intel_guc.c | 29 + drivers/gpu/drm/i915/gt/uc/intel_guc.h | 54 +- drivers/gpu/drm/i915/gt/uc/intel_guc_ads.c | 2 +- drivers/gpu/drm/i915/gt/uc/intel_guc_ct.c | 24 +- drivers/gpu/drm/i915/gt/uc/intel_guc_fwif.h | 34 +- .../gpu/drm/i915/gt/uc/intel_guc_submission.c | 1452 ++++++++++++++--- .../drm/i915/gt/uc/selftest_guc_multi_lrc.c | 179 ++ drivers/gpu/drm/i915/i915_query.c | 2 + drivers/gpu/drm/i915/i915_request.c | 143 +- drivers/gpu/drm/i915/i915_request.h | 23 + drivers/gpu/drm/i915/i915_vma.c | 21 +- drivers/gpu/drm/i915/i915_vma.h | 13 +- drivers/gpu/drm/i915/intel_wakeref.h | 12 + .../drm/i915/selftests/i915_live_selftests.h | 1 + include/uapi/drm/i915_drm.h | 139 +- 34 files changed, 3056 insertions(+), 693 deletions(-) delete mode 100644 Documentation/gpu/rfc/i915_parallel_execbuf.h create mode 100644 drivers/gpu/drm/i915/gt/uc/selftest_guc_multi_lrc.c
