Is there a way to check the amount of memory pinned by
i915_gem_object_get_pages_gtt(), it would be very helpful to check
system memory usage.
I think the pinned field in i915_gem_gtt has a different meaning and
doesn't indicate whether a gem object is pinned by
i915_gem_object_get_pages_gtt().
# cat /sys/kernel/debug/dri/0/i915_gem_gtt
ffff9fe1e9a7a3c0: X 4224KiB 3e 02 uncached dirty (pinned x
0) (ppgtt offset: 00c00000, size: 00420000, pages: 4K)

Though it includes a few non-shmemfs objects, see
debugfs/dri/0/i915_gem_objects and the "bound objects".
