[Intel-gfx] [PATCH 00/14] drm/i915: Make ILK/SNB/IVB use HSW watermark code

[ville.syrjala at linux.intel.com]

Back on the watermark horse. This series moves ILK/SNB/IVB over to the HSW
watermark code.

This series still has some underrun issues since the safe watermark
update mechanism is yet to be introduced. However it shouldn't really
be any worse than what we have ATM, and I'd like to have all the platforms
converted so that we have more systems that will excercise the new update
mechanism when it arrives.

Ville Syrjälä (14):
      drm/i915: Add IVB DDB partitioning control
      drm/i915: Add ILK/SNB/IVB WM latency field support
      drm/i915: Avoid computing invalid WM levels when sprites/scaling is enabled
      Revert "drm/i915/sprite: Always enable the scaler on IronLake"
      drm/i915: Fix LP1 sprite watermarks for ILK/SNB
      drm/i915: Fix LP1+ watermark disabling ILK
      drm/i915: Don't merge LP1+ watermarks on ILK/SNB/IVB when multiple pipes are enabled
      drm/i915: Disable FBC WM on ILK, and disable LP2+ when FBC is enabled
      drm/i915: Linetime watermarks are a HSW feature
      drm/i915: Disable LP1+ watermarks safely in init
      drm/i915: Move ILK/SNB/IVB over to the HSW WM code
      drm/i915: Try to fix the messy IVB sprite scaling workaround
      drm/i915: Don't disable primary when color keying is used
      drm/i915: Avoid underruns when disabling sprites
