| Series | [1/2] tracing, dma-buf: add a trace_dma_fence_sync_to event | expand |
This series adds new events to make it easier for tools like gpuvis or umr to graph the GPUs, kernel and applications activity. UMR patches using these events can be found here: https://gitlab.freedesktop.org/tomstdenis/umr/-/merge_requests/37 V1: https://patchwork.kernel.org/project/linux-media/patch/20240117184329.479554-1-pierre-eric.pelloux-prayer@amd.com/ Changes from V1: * uses trace_dma_fence_sync_to from dma-fence-chain.c * new amdgpu events * new drm plane commit event Pierre-Eric Pelloux-Prayer (6): tracing, dma-buf: add a trace_dma_fence_sync_to event dma-buf/fence-chain: use trace_dma_fence_sync_to amdgpu: use trace_dma_fence_sync_to in amdgpu_fence_sync drm/amdgpu: add BO clear event drm/amdgpu: add a amdgpu_cs_ioctl2 event drm: add drm_mode_atomic_commit event drivers/dma-buf/dma-fence-chain.c | 4 +++ drivers/dma-buf/dma-fence.c | 1 + .../gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c | 8 ++--- drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c | 16 +++++---- drivers/gpu/drm/amd/amdgpu/amdgpu_ids.c | 8 ++--- drivers/gpu/drm/amd/amdgpu/amdgpu_mes.c | 4 +-- drivers/gpu/drm/amd/amdgpu/amdgpu_object.c | 2 ++ drivers/gpu/drm/amd/amdgpu/amdgpu_sync.c | 11 ++++-- drivers/gpu/drm/amd/amdgpu/amdgpu_sync.h | 3 +- drivers/gpu/drm/amd/amdgpu/amdgpu_trace.h | 28 +++++++++++++++ drivers/gpu/drm/amd/amdgpu/amdgpu_umsch_mm.c | 4 +-- drivers/gpu/drm/drm_atomic_uapi.c | 19 +++++++++++ drivers/gpu/drm/drm_trace.h | 28 +++++++++++++-- include/trace/events/dma_fence.h | 34 +++++++++++++++++++ 14 files changed, 144 insertions(+), 26 deletions(-)

With the addition of drm_sched_job_add_dependency() and friends that would wire up some basic dependency tracking for a _lot_ of drivers. It should also be done before the amdgpu specific additions, because amdgpu is also using that and we don't want to duplicate fence dependency tracking in drivers that should be in common code.

This new event can be used to trace where a given dma_fence is added as a dependency of some other work. I plan to use it in amdgpu.
