v5 of this series which is adding a new ioctl to let userspace associate a free-form name to a drm_file. Having this name is useful when debugging or tracking resource usage; in particular when using virtio native-context driver, where a single process (say QEMU), uses 1 drm_file per-guest application. With this change, fdinfo and other tools can map each drm_file activity to the guest application. virglrenderer MR using this new ioctl to associate the context "debug_name" to the fd: https://gitlab.freedesktop.org/virgl/virglrenderer/-/merge_requests/1428 Changes since v4: * patches 1, 4 and 6 were slightly reworked based on Tvrtko' suggestions. v4: https://lists.freedesktop.org/archives/dri-devel/2024-September/471695.html Pierre-Eric Pelloux-Prayer (6): drm: add DRM_SET_CLIENT_NAME ioctl drm: use drm_file client_name in fdinfo drm/amdgpu: delay the use of amdgpu_vm_set_task_info drm/amdgpu: alloc and init vm::task_info from first submit drm/amdgpu: make process_name a flexible array drm/amdgpu: use drm_file::name in task_info::process_desc Documentation/gpu/drm-usage-stats.rst | 5 ++ drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h | 1 + .../gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c | 3 +- drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c | 6 +- drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c | 2 +- .../gpu/drm/amd/amdgpu/amdgpu_dev_coredump.c | 4 +- drivers/gpu/drm/amd/amdgpu/amdgpu_job.c | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c | 67 +++++++++++++------ drivers/gpu/drm/amd/amdgpu/amdgpu_vm.h | 4 +- drivers/gpu/drm/amd/amdgpu/gmc_v10_0.c | 2 +- drivers/gpu/drm/amd/amdgpu/gmc_v11_0.c | 2 +- drivers/gpu/drm/amd/amdgpu/gmc_v12_0.c | 2 +- drivers/gpu/drm/amd/amdgpu/gmc_v8_0.c | 2 +- drivers/gpu/drm/amd/amdgpu/gmc_v9_0.c | 2 +- drivers/gpu/drm/amd/amdgpu/sdma_v4_0.c | 2 +- drivers/gpu/drm/amd/amdgpu/sdma_v4_4_2.c | 2 +- drivers/gpu/drm/amd/amdkfd/kfd_events.c | 2 +- drivers/gpu/drm/amd/amdkfd/kfd_process.c | 3 + drivers/gpu/drm/drm_debugfs.c | 14 ++-- drivers/gpu/drm/drm_file.c | 10 +++ drivers/gpu/drm/drm_ioctl.c | 51 ++++++++++++++ include/drm/drm_file.h | 9 +++ include/uapi/drm/drm.h | 17 +++++ 23 files changed, 172 insertions(+), 42 deletions(-) -- 2.40.1
