As a prerequisite to merging the new Intel Xe DRM driver [1] [2], we have been asked to merge our common DRM scheduler patches first. This a continuation of a RFC [3] with all comments addressed, ready for a full review, and hopefully in state which can merged in the near future. More details of this series can found in the cover letter of the RFC [3]. These changes have been tested with the Xe driver. v2: - Break run job, free job, and process message in own work items - This might break other drivers as run job and free job now can run in parallel, can fix up if needed v3: - Include missing patch 'drm/sched: Add drm_sched_submit_* helpers' - Fix issue with setting timestamp to early - Don't dequeue jobs for single entity after calling entity fini - Flush pending jobs on entity fini - Add documentation for entity teardown - Add Matthew Brost to maintainers of DRM scheduler Matt [1] https://gitlab.freedesktop.org/drm/xe/kernel [2] https://patchwork.freedesktop.org/series/112188/ [3] https://patchwork.freedesktop.org/series/116055/ Matthew Brost (13): drm/sched: Add drm_sched_submit_* helpers drm/sched: Convert drm scheduler to use a work queue rather than kthread drm/sched: Move schedule policy to scheduler / entity drm/sched: Add DRM_SCHED_POLICY_SINGLE_ENTITY scheduling policy drm/sched: Split free_job into own work item drm/sched: Add generic scheduler message interface drm/sched: Add drm_sched_start_timeout_unlocked helper drm/sched: Start run wq before TDR in drm_sched_start drm/sched: Submit job before starting TDR drm/sched: Add helper to set TDR timeout drm/sched: Waiting for pending jobs to complete in scheduler kill drm/sched/doc: Add Entity teardown documentaion drm/sched: Update maintainers of GPU scheduler Documentation/gpu/drm-mm.rst | 6 + MAINTAINERS | 1 + .../drm/amd/amdgpu/amdgpu_amdkfd_arcturus.c | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c | 17 +- drivers/gpu/drm/amd/amdgpu/amdgpu_device.c | 15 +- drivers/gpu/drm/etnaviv/etnaviv_sched.c | 5 +- drivers/gpu/drm/lima/lima_sched.c | 5 +- drivers/gpu/drm/msm/adreno/adreno_device.c | 6 +- drivers/gpu/drm/msm/msm_ringbuffer.c | 5 +- drivers/gpu/drm/nouveau/nouveau_sched.c | 5 +- drivers/gpu/drm/panfrost/panfrost_job.c | 5 +- drivers/gpu/drm/scheduler/sched_entity.c | 111 +++- drivers/gpu/drm/scheduler/sched_fence.c | 2 +- drivers/gpu/drm/scheduler/sched_main.c | 497 ++++++++++++++---- drivers/gpu/drm/v3d/v3d_sched.c | 25 +- include/drm/gpu_scheduler.h | 96 +++- 16 files changed, 644 insertions(+), 159 deletions(-) -- 2.34.1
