* swrast: fix unmatched span->array->ChanTypeYuanhan Liu2011-11-211-0/+4
| | | | | | | | | | | texture_combine converts the result rgba to CHAN_TYPE from FLOAT. At the same time, make sure the span->array->ChanType is changed, too. v2: pick a nicer comment from Brian Signed-off-by: Yuanhan Liu <[email protected]> Reviewed-by: Brian Paul <[email protected]> Reviewed-by: Ian Romanick <[email protected]>
* swrast: simplify the prototype of function texture_combineYuanhan Liu2011-11-211-10/+9
| | | | | | | | | | | | Parameter n and rgbaChan are both from structure span, thus using span as paramter to simplify the prototype. Function texture_combine is only used by _swrast_texture_span, so I guess it's safe to do so. This patch is mainly for the next patch.

* swrast: fix delayed texel buffer allocation regressionBrian Paul2011-10-031-20/+20
| | | | | | | | Commit 617cdcd4c7b1cffb584c829c35bdf9c9bf04627b delayed the texel buffer allocation until texture_combine() is called. But the texel buffer is needed sooner in _swrast_texture_span() at line 649. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=41433
* mesa: Delay s_texcombine.c memory allocation until it's used.Eric Anholt2011-10-011-0/+20
| | | | | | Generally we're using fragment programs in all our drivers, so wasting 4MB for code that's never called is pretty lame. Reduces i965 memory allocation for a short shader program from 21,932,128B to 17,737,816B.
* mesa: s/INLINE/inline/Brian Paul2011-10-011-1/+1
| | | | | | | INLINE is still seen in some files (some generated files, etc) but this is a good start. Acked-by: Kenneth Graunke <[email protected]>
* swrast: initial multi-threaded span renderingAndreas Fänger2011-08-111-0/+4
| | | | | | | | Optional parallel rendering of spans using OpenMP. Initial implementation for aa triangles. A new option for scons is also provided to activate the openmp support (off by default). Signed-off-by: Brian Paul <[email protected]>
* swrast: anisotropic filtering extensionAndreas Faenger2011-05-181-0/+12
| | | | | | | | | Anisotropic filtering extension for swrast intended to be used by osmesa to create high quality renderings. Based on Higher Quality Elliptical Weighted Avarage Filter (EWA). A 2nd implementation using footprint assembly is also provided. Signed-off-by: Brian Paul <[email protected]>
* mesa: move sampler state into new gl_sampler_object typeBrian Paul2011-04-101-10/+12
| | | | | | 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().
* mesa: remove GL_SGI_texture_color_table supportBrian Paul2011-02-281-5/+0
| | | | | | It was only implemented in the swrast driver and probably not used by any applications. A modern app would use a dependent/chained texture lookup in the fragment shader.
