drm/i915: Expose client engine utilisation via fdinfo
Similar to AMD commit
874442541133 ("drm/amdgpu: Add show_fdinfo() interface"), using the
infrastructure added in previous patches, we add basic client info
and GPU engine utilisation for i915.
Example of the output:
pos: 0
flags: 0100002
mnt_id: 21
drm-driver: i915
drm-pdev: 0000:00:02.0
drm-client-id: 7
drm-engine-render: 9288864723 ns
drm-engine-copy: 2035071108 ns
drm-engine-video: 0 ns
drm-engine-video-enhance: 0 ns
v2:
* Update for removal of name and pid.
v3:
* Use drm_driver.name.
v4:
* Added drm-engine-capacity- tag.
* Fix typo. (Umesh)
v5:
* Don't output engine data before Gen8.
