From: Rob Clark <robdclark@xxxxxxxxxxxx> Similar motivation to other similar recent attempt[1]. But with an attempt to have some shared code for this. As well as documentation. It is probably a bit UMA-centric, I guess devices with VRAM might want some placement stats as well. But this seems like a reasonable start. Basic gputop support: https://patchwork.freedesktop.org/series/116236/ And already nvtop support: https://github.com/Syllo/nvtop/pull/204 [1] https://patchwork.freedesktop.org/series/112397/ Rob Clark (6): drm: Add common fdinfo helper drm/msm: Switch to fdinfo helper drm/amdgpu: Switch to fdinfo helper drm/i915: Switch to fdinfo helper drm: Add fdinfo memory stats drm/msm: Add memory stats to fdinfo Documentation/gpu/drm-usage-stats.rst | 31 +++++- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 3 +- drivers/gpu/drm/amd/amdgpu/amdgpu_fdinfo.c | 16 ++- drivers/gpu/drm/amd/amdgpu/amdgpu_fdinfo.h | 2 +- drivers/gpu/drm/drm_file.c | 111 +++++++++++++++++++++ drivers/gpu/drm/i915/i915_driver.c | 3 +- drivers/gpu/drm/i915/i915_drm_client.c | 18 +--- drivers/gpu/drm/i915/i915_drm_client.h | 2 +- drivers/gpu/drm/msm/msm_drv.c | 11 +- drivers/gpu/drm/msm/msm_gem.c | 15 +++ drivers/gpu/drm/msm/msm_gpu.c | 2 - include/drm/drm_drv.h | 7 ++ include/drm/drm_file.h | 5 + include/drm/drm_gem.h | 30 ++++++ 14 files changed, 220 insertions(+), 36 deletions(-) -- 2.39.2
