This patch series is part of the ongoing work to put together a compute stack on top of Gallium3D. What we have been doing until now to that end could be divided in 6 building blocks:
1/ Gallium API and TGSI changes (this patch series). 2/ Other fixes and additions to the gallium helper libraries that the state tracker needs to function. 3/ OpenCL state tracker. 4/ Implementation of this API for the r600g driver, and work on AMD's LLVM back-end. 5/ Implementation of this API for the nv50 driver, and related compiler changes based on Christoph's nv50/nvc0 codegen code. 6/ LLVM back-end that will be used along with clang to translate compute programs from the OpenCL language into TGSI. Block 2 will be sent for review as a separate patch series soon. I'm not sending block 3 in patch form because it's probably too bulky for this mailing list, and it's quite self-contained anyway, so, I've pushed it together with the other changes it depends on to the new 'gallium-compute' branch. Blocks 4-6 are still rather immature, but, for the curious: The radeon-specific bits can be found in the 'clover-r600-master' branch of Tom's mesa tree [1], and some of the work done for nouveau can be found in the 'nv50-compute' branch of my tree [2]. About this patch series: patches 1 and 11 are API changes that give compute powers to pipe_context and pipe_screen, patches 3-10 are the extensions to the TGSI language that will be used by the state tracker to represent compute programs, patch 2 is a refactoring required by patch 10. Comments, questions and r-b's are much appreciated.
