[Intel-gfx] [PATCH 0/3] Replace Blitter ring based flips with MMIO flips

[sourab.gupta at intel.com]

From: Sourab Gupta <sourab.gupta at intel.com>

Using MMIO based flips for Media power well residency optimization.
The blitter ring is currently being used just for command streamer based
flip calls. For pure 3D workloads, with MMIO flips, there will be no use
of blitter ring and this will ensure the 100% residency for Media well.

Sourab Gupta (3):
  drm/i915: Replaced Blitter ring based flips with MMIO flips
  drm/i915: Default to mmio flips on VLV
  drm/i915: Fix mmio page flip vs mmio set base race
