[Intel-gfx] [PATCH 00/15] [v2] Broadwell HW semaphore

[Ben Widawsky]

Reposting this as a new series since two of the patches dropped off
since last time.

Functionally it's the same as before. Like before, the patch "drm/i915:
unleash semaphores on gen8" should probably not be merged as it's not
100% clear where the hang is currently coming from. Everything else
should be pretty benign for other platforms.

Ben Widawsky (15):
  drm/i915: Reorder/respace MI instruction definition
  drm/i915: Don't emit mbox updates without semaphores
  drm/i915: Move semaphore specific ring members to struct
  drm/i915: Virtualize the ringbuffer signal func
  drm/i915: Move ring_begin to signal()
  drm/i915: Make semaphore updates more precise
  drm/i915: gen specific ring init
  drm/i915/bdw: implement semaphore signal
  drm/i915/bdw: implement semaphore wait
  drm/i915: FORCE_RESTORE for gen8 semaphores
  drm/i915/bdw: poll semaphores
  drm/i915: Extract semaphore error collection
  drm/i915/bdw: collect semaphore error state
  drm/i915: unleash semaphores on gen8
  drm/i915: semaphore debugfs
