[Intel-xe] [PATCH 0/7] drm/xe: fdinfo memory stats

[Tejas Upadhyay]

This series enables enables fdinfo memory stats for xe.

I added tracking of most classes of bo (user bo, page tables, ring, lrc) 
which contribute to client's memory usage. This follows similar lines to
what Rob's msm code and tvrtko's i915 code is doing with some xe way
of showing and tracking/fecthing objects which adds to client memory
stats.

Example fdinfo format:

#cat /proc/4620/fdinfo/3
pos:    0
flags:  0100002
mnt_id: 23
ino:    1116
