Hi all, This is a pretty big update following v2. The first big change is to drop the HW arbitration usage in favor of a software mechanism using a special priority in the scheduler. The second is a rework of the uAPI. Since we have a couple of execbuf uAPI changes for this series (VK_INTEL_performance_query) & timeline semaphores, we can come up with a more generic mechanism that could be extended in the future. Rather than reusing partially deprecated fields. Unfortunately (or not!) that requires timeline semaphores to be added to the series because we need to use cliprects_ptr that is already used by FENCE_ARRAY. Cheers, Lionel Landwerlin (7): drm/i915/perf: introduce a versioning of the i915-perf uapi drm/i915/perf: allow for CS OA configs to be created lazily drm/i915: introduce a mechanism to extend execbuf2 drm/i915: add syncobj timeline support drm/i915: add a new perf configuration execbuf parameter drm/i915/perf: allow holding preemption on filtered ctx drm/i915: add support for perf configuration queries .../gpu/drm/i915/gem/i915_gem_execbuffer.c | 437 +++++++++++++++--- drivers/gpu/drm/i915/gt/intel_engine_types.h | 7 + drivers/gpu/drm/i915/gt/intel_gpu_commands.h | 1 + drivers/gpu/drm/i915/gt/intel_lrc.c | 7 + drivers/gpu/drm/i915/gt/intel_ringbuffer.c | 4 +- drivers/gpu/drm/i915/i915_drv.c | 11 +- drivers/gpu/drm/i915/i915_drv.h | 37 +- drivers/gpu/drm/i915/i915_perf.c | 197 ++++++-- drivers/gpu/drm/i915/i915_priolist_types.h | 7 + drivers/gpu/drm/i915/i915_query.c | 279 +++++++++++ drivers/gpu/drm/i915/i915_request.c | 1 + drivers/gpu/drm/i915/i915_request.h | 1 + drivers/gpu/drm/i915/intel_guc_submission.c | 6 + include/uapi/drm/i915_drm.h | 211 ++++++++- 14 files changed, 1109 insertions(+), 97 deletions(-) -- 2.21.0.392.gf8f6787159e _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
