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. Based on drm-tip branch. A follow up series will be posted to address some of dakr requets for kernel doc changes. 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 v6: - Address Luben's feedback - Include base commit v7: - Drop SINGLE_ENTITY mode rather pull in Luben's patch for dynamic run queues - Address Luben's feedback for free_job work item patch v8: - Rebase on drm-tip which includes Luben's patch for dynamic run queues - Don't adjust comments, change variable names, function names twice in series - Don't move existing code to different places in a file to preserve git history 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 (5): drm/sched: Add drm_sched_wqueue_* helpers drm/sched: Convert drm scheduler to use a work queue rather than kthread drm/sched: Split free_job into own work item drm/sched: Add drm_sched_start_timeout_unlocked helper drm/sched: Add a helper to queue TDR immediately .../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 | 14 +- drivers/gpu/drm/etnaviv/etnaviv_sched.c | 2 +- drivers/gpu/drm/lima/lima_sched.c | 2 +- drivers/gpu/drm/msm/adreno/adreno_device.c | 6 +- drivers/gpu/drm/msm/msm_ringbuffer.c | 2 +- drivers/gpu/drm/nouveau/nouveau_sched.c | 2 +- drivers/gpu/drm/panfrost/panfrost_job.c | 2 +- drivers/gpu/drm/scheduler/sched_main.c | 301 ++++++++++++------ drivers/gpu/drm/v3d/v3d_sched.c | 10 +- include/drm/gpu_scheduler.h | 20 +- 12 files changed, 248 insertions(+), 130 deletions(-) base-commit: b560681c6bf623db41064ac486dd148d6c103e53 -- 2.34.1
