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.
