[Intel-gfx] [PATCH 00/12] Misc locking fixes and GEM debugging

[Tvrtko Ursulin]

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

A collection of patches addressing locking inversions, missing
locking, un-needed atomic waiting, more precision for the latter
and adding some infrastructure to catch some of these during
driver development.

Tvrtko Ursulin (12):
  drm/i915: Add wait_for_us
  drm/i915: Do not wait atomically for display clocks
  drm/i915/guc: Do not wait for firmware load atomically
  drm/i915/lrc: Do not wait atomically when stopping engines
  drm/i915: Kconfig for extra driver debugging
  drm/i915: Do not lie about atomic wait granularity
  drm/i915: GEM operations need to be done under the big lock
  drm/i915: Fix struct mutex vs. RPS lock inversion
  drm/i915/ilk: Move register read under spinlock
  drm/i915: Introduce dedicated object VMA iterator
  drm/i915: Introduce dedicated safe object VMA iterator
  drm/i915: Add BKL asserts to get page helpers
