From c35e0677fe1afee4f9975ffdcd3d772f37ae1ae7 Mon Sep 17 00:00:00 2001 From: Damien Lespiau Date: Wed, 16 Jan 2013 14:56:40 +0000 Subject: assembler: Adopt brw_structs.h from mesa 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.
