Hi All, So as discussed I've started working on a TGSI backend for llvm to use as a way to get compute going on nouveau (and other gpu-s). I'm still learning all the ins and outs of llvm so I do not have much to show yet. I've rebased Francisco's (curro's) latest version on top of llvm trunk, and added a commit on top to actual get it build with the latest trunk. So

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. Boris and Daniel, was this approximately what you had in mind? I have obviously not tested all of this with more than a compile, but the first patch is

This is my attempt to do it right. I have obviously not tested all of this with more than a compile, but patches 1 and 3 are enough to make the atmel-hlcdc driver do what I need (when patched
