+i915 DRM client usage stats implementation
+==========================================
+
+The drm/i915 driver implements the DRM client usage stats specification as
+documented in :ref:`drm-client-usage-stats`.
+
+Example of the output showing the implemented key value pairs and entirety of
+the currently possible format options:
+
+::
+
+      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-capacity-video:   2
+      drm-engine-video-enhance:   0 ns
+
+Possible `drm-engine-` key names are: `render`, `copy`, `video` and
+`video-enhance`.
