* gallium: allow setting of the internal stream output offsetZack Rusin2014-03-071-4/+5
| | | | | | | | | | | | | | | | D3D10 allows setting of the internal offset of a buffer, which is in general only incremented via actual stream output writes. By allowing setting of the internal offset draw_auto is capable of rendering from buffers which have not been actually streamed out to. Our interface didn't allow. This change functionally shouldn't make any difference to OpenGL where instead of an append_bitmask you just get a real array where -1 means append (like in D3D) and 0 means do not append.

* gallium: add texture gather support to gallium (v3)Dave Airlie2014-02-252-0/+42
| | | | | | | | | | | | | | | | | | | | | This adds support to gallium for a TG4 instruction, and two CAPs. The first CAP is required for GL_ARB_texture_gather. The second CAP is required to expose GL_ARB_gpu_shader5. However so far we haven't found any hardware that natively exposes the textureGatherOffsets feature from GL, so just lower it for now. If hardware appears for this we can add another CAP to allow TG4 to take 4 offsets. v2: add component selection src and a cap to say hw can do it. (st can use to help control GL_ARB_gpu_shader5/GLSL 4.00). Add docs. v3: rename to SM5, add docs. Reviewed-by: Roland Scheidegger <[email protected]> Signed-off-by: Dave Airlie <[email protected]>

* gallium/tgsi: correct typo propagated from NV_vertex_program1_1Erik Faye-Lund2014-02-071-1/+1
| | | | | | | | | | | | | | | | In the specification text of NV_vertex_program1_1, the upper limit of the RCC instruction is written as 1.884467e+19 in scientific notation, but as 0x5F800000 in binary. But the binary version translates to 1.84467e+19 rather than 1.884467e+19 in scientific notation. Since the lower-limit equals 2^-64 and the binary version equals 2^+64, let's assume the value in scientific notation is a typo and implement this using the value from the binary version instead.

* gallium: add bits for clipping points as tris (d3d-style)Roland Scheidegger2014-01-171-4/+11
| | | | | | | | | | | | | | | | | | | | | | OpenGL does whole-point clipping, that is a large point is either fully clipped or fully unclipped (the latter means it may extend beyond the viewport as long as the center is inside the viewport). d3d9 (d3d10 has no large points) however requires points to be clipped after they are expanded to a rectangle. (Note some IHVs are known to ignore GL rules at least with some hw/drivers.) Hence add a rasterizer bit indicating which way points should be clipped (some drivers probably will always ignore this), and add the draw interaction this requires. Drivers wanting to support this and using draw must support large points on their own as draw doesn't implement vp clipping on the expanded points (it potentially could but the complexity doesn't seem warranted), and the driver needs to do viewport scissoring on such points.

* gallium: Make TGSI_SEMANTIC_FOG register four-component wide.José Fonseca2013-11-211-7/+4
| | | | | | | | | | | | | | | | | | | | | | | D3D9 Shader Model 2 restricted the fog register to one component, http://msdn.microsoft.com/en-us/library/windows/desktop/bb172945.aspx , but that restriction no longer exists in Shader Model 3, and several WHCK tests enforce that. So this change: - lifts the single-component restriction TGSI_SEMANTIC_FOG from Gallium interface - updates the Mesa state tracker to enforce output fog has (f, 0, 0, 1) - draw module was updated to leave TGSI_SEMANTIC_FOG output registers alone Several gallium drivers that are going out of their way to clear TGSI_SEMANTIC_FOG components could be simplified in the future.

* draw: clean up setting stream out information a bitRoland Scheidegger2013-08-271-0/+2
| | | | | | | | | | | | | | | | | In particular noone is interested in the vertex count, so drop that, and also drop the duplicated num_primitives_generated / so.primitives_storage_needed variables in drivers. I am unable for now to figure out if primitives_storage_needed in SO stats (used for d3d10) should increase if SO is disabled, though the equivalent num_primitives_generated used for OpenGL definitely should increase. In any case we were only counting when SO is active both in softpipe and llvmpipe anyway so don't pretend there's an independent num_primitives_generated counter which would count always. (This means the PIPE_QUERY_PRIMITIVES_GENERATED count will still be wrong just as before, should eventually fix this by doing either separate counting for this query or adjust the code so it always counts this even if SO is inactive depending on what's correct for d3d10.)

* gallium: add new float comparison instructions returning integer masksRoland Scheidegger2013-08-131-16/+76
| | | | | | | | | | | | Newer graphic languages don't want messy float mask results but instead true "boolean" mask results for float comparisons. Otherwise just need to convert the floats back to integers. Need to keep the old opcodes however due to both legacy (gl and d3d9) needing them and because older hw can't really deal with integers. These new FSEQ/FSGE/FSLT/FSNE opcodes are part of integer API and hence must be supported if a driver claims to support glsl 1.30 (or PIPE_SHADER_CAP_INTEGERS).

Hence specify this is ignored along with the swizzle. (Other options would be to have multiple opcodes or specify the ret type modifier maybe in dst_reg as there's padding bits left there but it is the only instruction allowing this.)

* gallium: clarify shift behavior with shift count >= 32Roland Scheidegger2013-08-021-12/+18
| | | | | | | | | | | | | | | | | | Previously, nothing was said what happens with shift counts exceeding bit width of the values to shift. In theory 3 behaviors are possible: 1) undefined (classic c definition) 2) just shift out all bits (so result is zero, or -1 potentially for ashr) 3) mask the shift count to bit width - 1 API's either require 3) or are ok with 1). In particular, GLSL (as well as a couple uninteresting legacy GL extensions) is happy with undefined, whereas both OpenCL and d3d10 require 3). Consequently, most hw also implements 3). So, for simplicity we just specify that 3) is required rather than saying undefined and then needing state trackers to work around it. Also while here specify shift count as a vector, not scalar. As far as I can tell this was a doc bug, neither state trackers nor drivers used scalar shift count. Reviewed-by: Jose Fonseca <[email protected]>
