This patch series is aimed at providing UM with detailed memory profiling information in debug builds. It is achieved through a device-wide list of DRM GEM objects, and also implementing the ability to label BO's from UM through a new IOCTL.
The new debugfs file shows a list of driver DRM GEM objects in tabular mode. To visualise it, cat sudo cat /sys/kernel/debug/dri/*.gpu/gems. To test this functionality from UM, please refer to this Mesa patch series: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/34224 Changelog: v3: - Replaced kfree() with kfree_const() when freeing a bo label - Rearranged functions for delaing with GEMs list adding and deleting - Changed Kernel BO labelling format not to include quotes - Return error in labelling ioctl when string length is too long Adrián Larumbe (4): drm/panthor: Introduce BO labeling drm/panthor: Add driver IOCTL for setting BO labels drm/panthor: show device-wide list of DRM GEM objects over DebugFS drm/panthor: Display heap chunk entries in DebugFS GEMS file drivers/gpu/drm/panthor/panthor_device.c | 5 + drivers/gpu/drm/panthor/panthor_device.h | 11 ++ drivers/gpu/drm/panthor/panthor_drv.c | 66 ++++++++++ drivers/gpu/drm/panthor/panthor_gem.c | 158 +++++++++++++++++++++++ drivers/gpu/drm/panthor/panthor_gem.h | 60 +++++++++ drivers/gpu/drm/panthor/panthor_heap.c | 3 + include/uapi/drm/panthor_drm.h | 19 +++ 7 files changed, 322 insertions(+) -- 2.48.1
