* gallium: add TGSI_SEMANTIC_VERTEXID_NOBASE and TGSI_SEMANTIC_BASEVERTEXRoland Scheidegger2014-12-163-0/+10
| | | | | | | | | | | | | | | | | | | Plus a new PIPE_CAP_VERTEXID_NOBASE query. The idea is that drivers not supporting vertex ids with base vertex offset applied (so, only support d3d10-style vertex ids) will get such a d3d10-style vertex id instead - with the caveat they'll also need to handle the basevertex system value too (this follows what core mesa already does). Additionally, this is also useful for other state trackers (for instance llvmpipe / draw right now implement the d3d10 behavior on purpose, but with different semantics it can just do both). Doesn't do anything yet. And fix up the docs wrt similar values. v2: incorporate feedback from Brian and others, better names, better docs.

* draw: fixes for vertex shaders outputting layer or viewport indexRoland Scheidegger2014-11-191-9/+6
| | | | | | | | | | Mostly add a couple cases so we don't just check gs for this. There's only one gotcha, the built-in vp transform in the llvm vs can't handle it (this would be fixable though non-trivial due to vp index being non-constant for the SoA outputs, but we don't use it if there's a gs neither - the whole clip/vp transform integration there is suboptimal).

| | | | | | | | | | | The only place the enum pipe_type was used is for the TGSI sampler view return type. So make it a TGSI type. Note: it appears this part of TGSI isn't used by anyone so it may be removed in the future. v2: the new name is tgsi_return_type, not tgsi_type.

* gallivm,tgsi: fix idiv by zero crashrconde2014-09-171-4/+4
| | | | | | | | While the result of signed integer division by zero is undefined by glsl (and doesn't exist with d3d10), we must not crash, so need to make sure we don't get sigfpe much like udiv already does. Unlike udiv where we return 0xffffffff (as required by d3d10) there is no requirement right now to return anything specific so we use zero.
* tgsi: accept offsets for sample opcodes too in the text parserRoland Scheidegger2014-09-161-3/+2
| | | | | | | | | | sample opcodes are a little oddly represented in the opcode_info, since they don't count as texture instructions - they don't have valid target information, but they may have offsets (unlike "ordinary" texture instructions, the texture token may be optional for them). So just make sure with these opcodes the optional offsets are accepted. Reviewed-by: Jose Fonseca <[email protected]>
* tgsi: don't print texture target for sample opcodesRoland Scheidegger2014-09-161-2/+5

| | | | | | | | | | | | | | Replace the plain sampler index with a register reference to a sampler. We also need to keep track of the sampler array size when there is a relative reference so that we can mark the whole array used. To facilitate implementation, we add a separate ADDR register that exclusively handles the sampler relative address. Other approaches would be more invasive.

* gallium: remove PIPE_SHADER_CAP_MAX_ADDRSMarek Olšák2014-08-111-3/+0
| | | | | | | | | | | | | | | This limit is fixed in Mesa core and cannot be changed. It only affects ARB_vertex_program and ARB_fragment_program. The minimum value for ARB_vertex_program is 1 according to the spec. The maximum value for ARB_vertex_program is limited to 1 by Mesa core. The value should be zero for ARB_fragment_program, because it doesn't support ARL. Finally, drivers shouldn't mess with these values arbitrarily. Reviewed-by: Ilia Mirkin <[email protected]>
* draw: hack around weird primitive id input in gsRoland Scheidegger2014-08-081-3/+3
| | | | | | | | | | | | | | | | | | | | | | The distinction between system values and ordinary inputs is not very obvious in gallium - further fueled by the fact that they use the same semantic names. Still, if there's any value which imho really is a system value, it's the primitive id input into the gs (while earlier (tessleation) stages could read it, it is _always_ generated by the system). For some odd reason though (which I'd classify as a bug but seems too complicated to fix) the glsl compiler in mesa treats this as an ordinary varying, and everything else after that (including the state tracker and other drivers) just go along with that. But input fetching in gs for llvm based draw was definitely limited to the ordinary (2-dimensional) inputs so only worked with other state trackers, the code was also additionally relying on tgsi_scan_shader filling uses_primid correctly which did not happen neither (would set it only for all stages if it was a system value, but only set it for the fragment shader if it was an input value). This fixes piglit glsl-1.50-geometry-primitive-id-restart and primitive-id-in in llvmpipe. Reviewed-by: Brian Paul <[email protected]>
