Intel's Eric Anholt and Ian Romanick have each published a large number of patches to the Mesa development list. Eric dropped a series of 37 patches that implement his MapTextureImage work for OpenGL while Ian Romanick has nine patches today for his Mesa IR cleaning.

Eric's patch series begins here and is for the MapTextureImage/UnmapTextureImage work he has been working on for a while via his mti-tested branch and the Mesa map-texture-image-v4 branch. This code isn't producing any regressions for the Intel driver or Softpipe, but the Radeon driver has one regression and the Nouveau driver has un-tested code in place. Even so, Eric is hoping to get these patches pushed into mainline straight away since they can be easily bisected and it works well for lowering the maintenance burden of classic Mesa drivers. This affects Gallium3D drivers too with the Mesa state tracker.

Meanwhile, Ian Romanick has been cleaning up the ir_to_mesa code and adding new capabilities there. There's also now a partial constant propagation pass for Mesa IR that cleans up the generated code from IR-to-Mesa on the Intel driver. This patch series begins here.
