[Intel-gfx] [PATCH v2 0/5] fdinfo memory stats

[Tvrtko Ursulin]

From: Tvrtko Ursulin <tvrtko.ursulin at intel.com>

Second try, this time actually per client! :)

I added tracking of most classes of objects which contribute to clients memory
footprint and accouting along the similar lines as in Rob's msm code. Then
printing it out to fdinfo using the drm helper Rob added.

Example fdinfo with the series applied:

# cat /proc/1383/fdinfo/8
pos:    0
flags:  02100002
mnt_id: 21
ino:    397

drm-client-id:  18
drm-pdev:       0000:00:02.0
drm-total-system:       125 MiB
drm-shared-system:      16 MiB
drm-active-system:      110 MiB
drm-resident-system:    125 MiB
drm-purgeable-system:   2 MiB
drm-total-stolen-system:        0
drm-shared-stolen-system:       0
drm-active-stolen-system:       0
drm-resident-stolen-system:     0
drm-purgeable-stolen-system:    0
drm-engine-render:      25662044495 ns
drm-engine-copy:        0 ns
drm-engine-video:       0 ns
drm-engine-video-enhance:       0 ns
