This patch series enables display of the size of driver-owned shmem BO's that aren't exposed to userspace through a DRM handle. Discussion of previous revision can be found here [1]. Changelog: v5: - Replaced down_write semaphore with the read flavour - Fixed typo and added explicit description for drm-shared-internal in the fdinfo documentation file for Panthor. v4: - Remove unrelated formating fix - Moved calculating overall size of a group's kernel BO's into its own static helper. - Renamed group kernel BO's size aggregation function to better reflect its actual responsibility.
