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: v7: - Added new commit: mentions the formation rules for driver-specific fdinfo keys - Added new commit: adds a helper that lets driver print memory size key:value pairs with their driver name as a prefix. - Modified later commits to make use of the previous ones. - Deleted mentions of now unnecessary memory keys in the old revision. v6: - Replace up_write with up_read, which was left out in the previous version - Fixed some minor comment and documentation issues reported by the kernel test robot 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.
