J . Mercier" Errors-To: dri-devel-bounces@lists.freedesktop.org Sender: "dri-devel" From: Tvrtko Ursulin Use the newly added drm_print_memory_stats helper to show memory utilisation of our objects in drm/driver specific fdinfo output. To collect the stats we walk the per memory regions object lists and accumulate object size into the respective drm_memory_stats categories. Objects with multiple possible placements are reported in multiple regions for total and shared sizes, while other categories are counted only for the currently active region.
