* gallium/docs: document alpha_to_coverage and alpha_to_one blend stateBrian Paul2016-09-161-0/+12
| | | | | | | | The gallium interface defines these like DX10. Note that OpenGL ignores these options if MSAA is disabled or the dest buffer doesn't support MSAA. Reviewed-by: Roland Scheidegger <[email protected]>
* gallium: Add a cap for offset_units_unscaledAxel Davy2016-06-251-0/+6
| | | | | | | | | | | | | | D3D9 has a different behaviour for depth bias. For OGL/D3D1X, the depth bias unit is the minimal resolvable value for the depth buffer, which depends on the format (and has different behaviour for float depth buffers). For D3D9, the depth bias unit is 1.0f. Signed-off-by: Axel Davy <[email protected]> Reviewed-by: Marek Olšák <[email protected]>

* 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.

* st/mesa: optionally apply texture swizzle to border color v2Christoph Bumiller2013-04-181-2/+4
| | | | | | | | | | | | This is the only sane solution for nv50 and nvc0 (really, trust me), but since on other hardware the border colour is tightly coupled with texture state they'd have to undo the swizzle, so I've added a cap. The dependency of update_sampler on the texture updates was introduced to avoid doing the apply_depthmode to the swizzle twice. v2: Moved swizzling helper to u_format.c, extended the CAP to provide more accurate information.
* gallium: add TGSI_SEMANTIC_TEXCOORD,PCOORD v3Christoph Bumiller2013-03-201-0/+5
| | | | | | | | | | | | | | | This makes it possible to identify gl_TexCoord and gl_PointCoord for drivers where sprite coordinate replacement is restricted. The new PIPE_CAP_TGSI_TEXCOORD decides whether these varyings should be hidden behind the GENERIC semantic or not. With this patch only nvc0 and nv30 will request that they be used. v2: introduce a CAP so other drivers don't have to bother with the new semantic v3: adapt to introduction gl_varying_slot enum

Also, don't need separate sprite enable bit - if all coords have it diabled, then there are no point sprites (technically, there's a distinction in pre-GL3, but it only differs in having more leniency in clamping to max size, something the state tracker would need to handle and the hardware won't bother anyway).
