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 I've combined the separate series to add comm/cmdline override onto the end of this, simply out of convenience (they would otherwise conflict in a bunch of places). v2: Extend things to allow for multiple regions other than just system "memory", make drm_show_memory_stats() a helper so that, drivers can use it or not based on their needs (but in either case, re- use drm_print_memory_stats() v3: Docs fixes v4: use u64 for drm_memory_stats, small docs update and collected Tvrtko's a-b [1] https://patchwork.freedesktop.org/series/112397/ Rob Clark (9): drm/docs: Fix usage stats typos drm: Add common fdinfo helper drm/msm: Switch to fdinfo helper drm/amdgpu: Switch to fdinfo helper drm: Add fdinfo memory stats drm/msm: Add memory stats to fdinfo drm/doc: Relax fdinfo string constraints drm/fdinfo: Add comm/cmdline override fields drm/msm: Wire up comm/cmdline override for fdinfo Documentation/gpu/drm-usage-stats.rst | 101 ++++++++++---- 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 | 147 +++++++++++++++++++++ drivers/gpu/drm/msm/adreno/adreno_gpu.c | 24 +++- drivers/gpu/drm/msm/msm_drv.c | 15 ++- drivers/gpu/drm/msm/msm_gem.c | 15 +++ drivers/gpu/drm/msm/msm_gpu.c | 2 - drivers/gpu/drm/msm/msm_gpu.h | 10 ++ include/drm/drm_drv.h | 7 + include/drm/drm_file.h | 51 +++++++ include/drm/drm_gem.h | 32 +++++ 13 files changed, 378 insertions(+), 47 deletions(-) -- 2.40.1
