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.
