From: Tvrtko Ursulin <[e-mail]>

Continuing on the identically named thread. First six patches are i915 specific
so please mostly look at the last one only which discusses the common options
for DRM drivers.

I haven't updated intel_gpu_top to use this yet so can't report any performance
numbers.

Tvrtko Ursulin (7):
  drm/i915: Explicitly track DRM clients
  drm/i915: Update client name on context create
  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/i915: Expose client engine utilisation via fdinfo
