[PATCH 0/7] Per client GPU stats

[Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com>]

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

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
