Hi, The initial goal of this series was to improve the drm and amdgpu trace events to be able to expose more of the inner workings of the scheduler and drivers to developers via tools. Then, the series evolved to become focused only on gpu_scheduler. The changes around vblank events will be part of a different series, as well as the amdgpu ones. Moreover Sima suggested to make some trace events stable uAPI, so tools can rely on them long term. The first patches extend and cleanup the gpu scheduler events. The last one adds a documentation entry in drm-uapi.rst. Changes since v5: * Addressed Christian, Maíra and Lucas' comments. * Added patch 1, 2, 6 to include drm_client_id to the events. This is required when a single app uses multiple fds for the same device. * Validated that the patches don't break gpuvis Useful links: - userspace tool using the updated events: https://gitlab.freedesktop.org/tomstdenis/umr/-/merge_requests/37 - v5: https://lists.freedesktop.org/archives/dri-devel/2024-June/457827.html Pierre-Eric Pelloux-Prayer (7): drm/debugfs: output client_id in in drm_clients_info drm/sched: store the drm client_id in drm_sched_fence drm/sched: add device name to the drm_sched_process_job event drm/sched: cleanup gpu_scheduler trace events drm/sched: trace dependencies for gpu jobs drm/sched: add the drm_client_id to the drm_sched_run/exec_job events drm/doc: document some tracepoints as uAPI Documentation/gpu/drm-uapi.rst | 19 +++ drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.c | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c | 3 +- drivers/gpu/drm/amd/amdgpu/amdgpu_job.c | 8 +- drivers/gpu/drm/amd/amdgpu/amdgpu_job.h | 3 +- drivers/gpu/drm/drm_debugfs.c | 10 +- drivers/gpu/drm/etnaviv/etnaviv_gem_submit.c | 2 +- drivers/gpu/drm/imagination/pvr_job.c | 2 +- drivers/gpu/drm/imagination/pvr_queue.c | 5 +- drivers/gpu/drm/imagination/pvr_queue.h | 2 +- drivers/gpu/drm/lima/lima_gem.c | 2 +- drivers/gpu/drm/lima/lima_sched.c | 6 +- drivers/gpu/drm/lima/lima_sched.h | 3 +- drivers/gpu/drm/msm/msm_gem_submit.c | 8 +- drivers/gpu/drm/nouveau/nouveau_sched.c | 3 +- drivers/gpu/drm/panfrost/panfrost_drv.c | 2 +- .../gpu/drm/scheduler/gpu_scheduler_trace.h | 121 ++++++++++++++---- drivers/gpu/drm/scheduler/sched_entity.c | 8 +- drivers/gpu/drm/scheduler/sched_fence.c | 4 +- drivers/gpu/drm/scheduler/sched_main.c | 8 +- drivers/gpu/drm/v3d/v3d_submit.c | 2 +- drivers/gpu/drm/xe/xe_sched_job.c | 3 +- include/drm/gpu_scheduler.h | 12 +- 23 files changed, 181 insertions(+), 57 deletions(-) -- 2.43.0
