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 v4: - Drop message interface - Drop 'Flush pending jobs on entity fini' - Drop 'Add documentation for entity teardown' - Address all feedback v5: - Address Luben's feedback - Drop starting TDR after calling run_job() - Drop adding 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 (7): drm/sched: Add drm_sched_wqueue_* helpers drm/sched: Convert drm scheduler to use a work queue rather than kthread drm/sched: Move schedule policy to scheduler drm/sched: Add DRM_SCHED_POLICY_SINGLE_ENTITY scheduling policy drm/sched: Split free_job into own work item drm/sched: Add drm_sched_start_timeout_unlocked helper drm/sched: Add helper to queue TDR immediately for current and future jobs .../drm/amd/amdgpu/amdgpu_amdkfd_arcturus.c | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c | 15 +- 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 | 7 +- drivers/gpu/drm/nouveau/nouveau_sched.c | 5 +- drivers/gpu/drm/panfrost/panfrost_job.c | 5 +- drivers/gpu/drm/scheduler/sched_entity.c | 86 ++- drivers/gpu/drm/scheduler/sched_fence.c | 2 +- drivers/gpu/drm/scheduler/sched_main.c | 506 ++++++++++++------ drivers/gpu/drm/v3d/v3d_sched.c | 25 +- include/drm/gpu_scheduler.h | 48 +- 14 files changed, 499 insertions(+), 233 deletions(-) -- 2.34.1
