* swrast: Remove support for the NV_fragment_program extension.Kenneth Graunke2012-10-161-5/+0
| | | | | | | | No hardware drivers support this, it's obsolete, and unlikely to be useful without NV_vertex_program, which is gone now. Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Eric Anholt <[email protected]>
* swrast: Support sampler object for texture fetching statePauli Nieminen2012-08-011-7/+10
| | | | | | | | | | | | swrast needs to pass sampler object into all texture fetching functions to use correct sampling state when sampler object is bound to the unit. The changes were made using half manual regular expression replace. v2: Fix NULL deref in _swrast_choose_triangle(), because the _Current values aren't set yet, so we need to look at our texObj2D.

* swrast: Only avoid empty _TexEnvProgramsIan Romanick2012-02-151-1/+2
| | | | | | | | | | | | | | If the generated shader for _TexEnvProgram is empty, force the use of the fixed-function code. Otherwise, go ahead and use the shader. This works around a mysterious issue on i915 where fixed-function software fallbacks are not working correctly. This isn't really the fix we want, but it works around the issue.

* swrast: Fix fixed-function fragment processingChad Versace2012-01-271-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On i965, _mesa_ir_link_shader is never called. As a consequence, the current fragment program (ctx->FragmentProgram->_Current) exists but is invalid because it has no instructions. Yet swrast continued to attempt to use the empty program. To avoid using the empty program, this patch 1) defines a new function, _swrast_use_fragment_program, which checks if the current fragment program exists and differs from the fixed function fragment program, and, when appropriate, 2) replaces checks of the form if (ctx->FragmentProgram->_Current == NULL) with if (_swrast_use_fragment_program(ctx)) Fixes the following oglconform regressions on i965/gen6: api-fogcoord(basic.allCases.log) api-mtexcoord(basic.allCases.log) api-seccolor(basic.allCases.log) api-texcoord(basic.allCases.log) blend-separate(basic.allCases) colorsum(basic.allCases.log) The tests were ran with the GLXFBConfig: visual x bf lv rg d st colorbuffer sr ax dp st accumbuffer ms cav id dep cl sp sz l ci b ro r g b a F gb bf th cl r g b a ns b eat ---------------------------------------------------------------------------- 0x021 24 tc 0 32 0 r y . 8 8 8 8 . . 0 24 8 0 0 0 0 0 0 None (Note: I originally believed that the hunk in _swrast_update_fragment_program was unnecessary. But it is required to fix blend-separate.) Note: This is a candidate for the 8.0 branch.

* mesa: move sampler state into new gl_sampler_object typeBrian Paul2011-04-101-3/+3
| | | | | | gl_texture_object contains an instance of this type for the regular texture object sampling state. glGenSamplers() generates new instances of gl_sampler_object which can override that state with glBindSampler().

* swrast: Implement ARB_fragment_coord_conventions but don't enable.Eric Anholt2010-01-261-0/+10
| | | | | | | | | | | This brings swrast's support up to the state of gallium, and fixes the default center behavior of fragment.position.xy in piglit fp-arb-fragment-coord-conventions-none. The extension is not enabled currently because the GLSL part of the extension isn't supported, so piglit glsl-arb-fragment-coord-conventions-define fails as would any serious test of the GLSL part.

* Merge branch 'outputswritten64'Ian Romanick2009-11-171-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | Add a GLbitfield64 type and several macros to operate on 64-bit fields. The OutputsWritten field of gl_program is changed to use that type. This results in a fair amount of fallout in drivers that use programs. No changes are strictly necessary at this point as all bits used are below the 32-bit boundary. Fairly soon several bits will be added for clip distances written by a vertex shader. This will cause several bits used for varyings to be pushed above the 32-bit boundary. This will affect any drivers that support GLSL. At this point, only the i965 driver has been modified to support this eventuality. I did this as a "squash" merge. There were several places through the outputswritten64 branch where things were broken. I foresee this causing difficulties later for bisecting. The history is still available in the branch.

Now each of those things are separate fragment program attributes. This simplifies quite a few things in Mesa and gallium.

* Updated GLSL uniform/sampler handling from gallium-0.1 branchBrian Paul2008-05-141-5/+9
| | | | | | | | | | Previously, the shader linker combined the uniforms used by the vertex and fragment shaders into a combined set of uniforms. This made the implementation of glUniform*() simple, but was rather inefficient otherwise. Now each shader gets its own set of uniforms (no more modelview matrix showing up in the fragment shader uniforms, for example). cherry-picked by hand from gallium-0.1 branch

| | | | | | | | | | | These fields are no longer indexed by shader output. Now, we just have a simple array of renderbuffer pointers. If the shader writes to gl_FragData[i], send those colors to the N _ColorDrawBuffers. Otherwise, replicate the single gl_FragColor (or the fixed-function color) to the N _ColorDrawBuffers. A few more changes and simplifications can follow from this...
