[PATCH 0/7] Per client GPU stats

Same old work but now rebased and series ending with some DRM docs proposing
the common specification which should enable nice common userspace tools to be
written.

For the moment I only have intel_gpu_top converted to use this and that seems to
work okay.

v2:
* Added prototype of possible amdgpu changes and spec updates to align with the
common spec.

v3:
* Documented that 'drm-driver' tag shall correspond with
struct drm_driver.name.

v4:
* Dropped amdgpu conversion from the series for now until AMD folks can find
some time to finish that patch.

Tvrtko Ursulin (7):
drm/i915: Explicitly track DRM clients
drm/i915: Make GEM contexts track DRM clients
drm/i915: Track runtime spent in closed and unreachable GEM contexts
drm/i915: Track all user contexts per client
drm/i915: Track context current active time
drm: Document fdinfo format specification
drm/i915: Expose client engine utilisation via fdinfo
