It will display a series of key:value pairs under /proc/pid/fdinfo/fd for render processes that open the Panfrost DRM file. The pairs contain basic drm gpu engine and memory region information that can either be cat by a privileged user or accessed with IGT's gputop utility. Changelog: v1: https://lore.kernel.org/lkml/bb52b872-e41b-3894-285e-b52cfc849782@arm.com/T/ v2: https://lore.kernel.org/lkml/20230901084457.5bc1ad69@collabora.com/T/ - Changed the way gpu cycles and engine time are calculated, using GPU registers and taking into account potential resets. - Split render engine values into fragment and vertex/tiler ones. - Added more fine-grained calculation of RSS size for BO's. - Implemente selection of drm-memory region size units - Removed locking of shrinker's mutex in GEM obj status function v3: - Changed fdinfo engine names to something more descriptive - Mentioned GPU cycle counts aren't an exact measure - Handled the case when job->priv might be NULL - Handled 32 bit overflow of cycle register - Kept fdinfo drm memory stats size unit display within 10k times the previous multiplier for more accurate BO size numbers - Removed special handling of Prime imported BO RSS - Use rss_size only for heap objects - Use bo->base.madv instead of specific purgeable flag - Fixed kernel test robot warnings Adrián Larumbe (8): drm/panfrost: Add cycle count GPU register definitions drm/panfrost: Enable cycle counter register upon job submission drm/panfrost: Enable debugfs toggling of cycle counter register drm/panfrost: Add fdinfo support GPU load metrics drm/panfrost: Add fdinfo support for memory stats drm/drm_file: Add DRM obj's RSS reporting function for fdinfo drm/panfrost: Implement generic DRM object RSS reporting function drm/drm-file: Show finer-grained BO sizes in drm_show_memory_stats drivers/gpu/drm/drm_file.c | 7 ++- drivers/gpu/drm/panfrost/Makefile | 2 + drivers/gpu/drm/panfrost/panfrost_debugfs.c | 51 ++++++++++++++++ drivers/gpu/drm/panfrost/panfrost_debugfs.h | 13 +++++ drivers/gpu/drm/panfrost/panfrost_devfreq.c | 8 +++ drivers/gpu/drm/panfrost/panfrost_devfreq.h | 3 + drivers/gpu/drm/panfrost/panfrost_device.c | 5 ++ drivers/gpu/drm/panfrost/panfrost_device.h | 19 ++++++ drivers/gpu/drm/panfrost/panfrost_drv.c | 65 ++++++++++++++++++++- drivers/gpu/drm/panfrost/panfrost_gem.c | 28 +++++++++ drivers/gpu/drm/panfrost/panfrost_gem.h | 5 ++ drivers/gpu/drm/panfrost/panfrost_gpu.c | 43 ++++++++++++++ drivers/gpu/drm/panfrost/panfrost_gpu.h | 6 ++ drivers/gpu/drm/panfrost/panfrost_job.c | 37 ++++++++++++ drivers/gpu/drm/panfrost/panfrost_job.h | 5 ++ drivers/gpu/drm/panfrost/panfrost_mmu.c | 12 ++-- drivers/gpu/drm/panfrost/panfrost_regs.h | 5 ++ include/drm/drm_gem.h | 9 +++ 18 files changed, 316 insertions(+), 7 deletions(-) create mode 100644 drivers/gpu/drm/panfrost/panfrost_debugfs.c create mode 100644 drivers/gpu/drm/panfrost/panfrost_debugfs.h base-commit: f45acf7acf75921c0409d452f0165f51a19a74fd
