Hi all, I have been a little bit out of the loop on the mesa side, thus now i am having a bunch of questions relating to gallium, apologies if i am asking for obvious thing.
First in tgsi compiler there is a Dimension field (struct tgsi_dimension) that i don't understand, it seems all driver are ignoring it, from quick glimpse to tgsi code it's for 2d array addressing, but i think glsl only talks about 1d array. What are the exepction for this field ? Should driver care ? What is the indirect boolean for in src or dst operand of an instruction ? What is the GLSL equivalent of it. Also i think GLSL state that the sampler information should be defined at shader build time but the TGSI doesn't seems to provide those, for r600 i need to have a shader rewritting because of this (it's not big and i don't mind much and i also can avoid rewritting by checking if there is a change in the bound sampler). A more practical question are what are the gallium branches likely to be merge in the next few weeks ? I will likely have r600g driver in good shape enough in the next few weeks to consider merging it with master but i would like first to port it to the lastest gallium change before merging it so i don't put the burden on people working on those branches. What are the plan to expand TGSI to support new shader feature ? (double precision op, ...) Thanks to who ever can shed some light on those question for me :) Cheers, Jerome ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
