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.collabora.com/alarumbe/mesa/-/commits/bo-tagging-panthor-gl 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 | 8 ++ drivers/gpu/drm/panthor/panthor_drv.c | 57 +++++++++++ drivers/gpu/drm/panthor/panthor_gem.c | 119 +++++++++++++++++++++++ drivers/gpu/drm/panthor/panthor_gem.h | 34 +++++++ drivers/gpu/drm/panthor/panthor_heap.c | 15 +++ include/uapi/drm/panthor_drm.h | 14 +++ 7 files changed, 252 insertions(+) -- 2.48.1
