* gallium: remove PIPE_SHADER_CAP_MAX_ADDRSMarek Olšák2014-08-111-1/+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]>

* 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.

| | | | | | | | | | | | | | | | | | | | | | | 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.
