Finally merge both brw_structs.h from mesa. One detail has risen in that last commit, the msg_control field of data port message descriptors. Mesa's msg_control field is sometimes split with messages-specific fields where the assembler (at least for recent generations) exposes the full msg_control value in the send instruction. As libva's shaders encodes the full msg_control value in its send instructions, I've chosen to not take the split msg_control from mesa. It's absolutely possible to have a patch fixing that divergence at some later point. I've also kept a hack introduced with ironlake to not have to rewrite shaders (that encode msg_control in the text, remember), and thus creates a another difference with Mesa. - GLuint msg_control:3; - GLuint msg_type:3; + GLuint msg_control:4; + GLuint msg_type:2; Once again, I've made sure that re-generating libva's shaders don't show any difference.

intel-gen4asm is a program to compile an assembly language for the Intel 965 Express Chipset. It has been used to construct programs for textured video in the 2d driver. Some examples of gen4 assembly programs are in the doc/examples directory. Note that the language parsed by this assembler is not exactly what the final language is going to look like. In particular, the send instructions need to be cleaned up and made more reasonable to program with.
