[Mesa-dev] [PATCH 0/6] i965: Misc sRGB and CCS fixes

[Eero Tamminen]

Hi,

This series increases performance except in SynMark DrvState, where drop 
is acceptable & expected [1].

BXT J4205 improvements:
  1-2% in GfxBench Manhattan 3.1
  1% in GfxBench CarChase & SynMark Deferred

KBL GT2 improvements:
  2-3% in GfxBench Manhattan 3.1
  1-2% in GfxBench CarChase & SynMark Deferred

KBL GT3e improvements:
  ~2% in GfxBench Manhattan 3.1 & CarChase and SynMark Deferred

By accident I had left Aztec Ruins out, but I assume ~1% drop in that is 
also fixed.

[1] SynMark DrvState drops few percent because of the CPU overhead with 
fast clear resolving for numerous small viewports.
