* intel: Enable S3TC extensions alwaysIan Romanick2013-01-231-6/+4
| | | | | | | | | | | | | | | | | | | | | Always enable the use of pre-compressed texture data. The ability to perform on-line compression still requires the presence of libtxc_dxtn or an explicit driconf over-ride. Applications that just want to submit precompessed data when an on-line compressor is not available can look for the GL_EXT_texture_compression_dxt1 and GL_ANGLE_texture_compression_dxt[35] extensions. v2: Only enable the extensions that do not require on-line compression by default. The previous statement "This should not impact many (if any) real applications." proved to be false for at least Sauerbraten. This application mostly submits pre-compressed data, but it also can submit uncompressed data that it asks the driver to compress.

| | | | | | | | | | | | | For non-generic compressed format we assert two things: 1. The format has already been validated against the set of available extensions. 2.

* i965: Use swizzles to force R, G, and B to 0.0 for ALPHA textures.Carl Worth2013-01-231-3/+10
| | | | | | | | | | | | | | | | | Similar to the previous commit, we may be using a texture with actual RGBA storage for the GL_ALPHA format, so force the color values to 0.0. This commit fixes the following piglit (sub) tests: EXT_texture_snorm/fbo-blending-formats GL_ALPHA16_SNORM GL_ALPHA8_SNORM GL_ALPHA_SNORM Note: Haswell bypasses this swizzle code, so may require an independent fix for this bug.

* i965: Use swizzles to force alpha to 1.0 for RED, RG, or RGB textures.Carl Worth2013-01-231-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We may be using a texture with actual RGBA storage for these formats, so force the alpha value read to 1.0. This commit fixes the following piglit (sub) tests: ARB_texture_float/fb-blending-formats GL_RGB16F_ARB EXT_framebuffer_object/fbo-blending-formats GL_RGB10 GL_RGB12 GL_RGB16 EXT_texture_snorm/fbo-blending-formats GL_RGB16_SNORM GL_RGB8_SNORM GL_RGB_SNORM These test improvements depend on the previous commit as well. That commit smashes alpha to 1.0 for the case of ReadPixels (so fixes "FBO testing" as reported by this test), while this commit smashes alpha to 1.0 for the case of texturing (fixed the "window testing" as reported by this test). Note: Haswell bypasses this swizzle code, so may require an independent fix for this bug. Reviewed-by: Eric Anholt <[email protected]>
* ReadPixels: Force ALPHA to 1 while rebasing RGBA values for GL_RGB formatCarl Worth2013-01-231-0/+10
| | | | | | | | | | | | | | | | | | | | | | When performing a ReadPixels operation, we may be reading from a buffer that stores alpha values, but that is actually representing a buffer with no alpha channel. In this case, while rebasing the values, touch up all alpha values read to 1.0. This commit fixes the following piglit (sub) tests: ARB_texture_float/fbo-colormask-formats GL_RBG16F_ARB EXT_texture_snorm/fbo-colormask-formats GL_RGB16_SNORM GL_RGB8_SNORM GL_RGB_SNORM It likely improves the results of other tests as well, but a PASS remains elusive due to additional bugs.

* i965: Examine _BaseFormat when deciding to perform xRGB_alpha fixupsCarl Worth2013-01-231-1/+2
| | | | | | | | | | | | | | | | | | | | | The renderbuffer's Format field may have an alpha channel even when the underlying _BaseFormat does not. This can happen when mesa chooses to use RGBA16 for an RGB16 format, for example. So look at _BaseFormat when deciding whether to fixup the blend factors. This test improves the results of at least the following piglit tests: EXT_frambebuffer_object/fbo-blending-formats {GL_RGB10, GL_RGB12, GL_RGB16} EXT_texture_snorm/fbo-blending-formats {GL_RGB16_SNORM, GLRGB8_SNORM, GL_RGB_SNORM} But none of these actually change from FAIL to PASS yet. The R, G, and B probe values are fixed with this commit, but the tests still fail because the alpha values are still wrong. Reviewed-by: Eric Anholt <[email protected]>
* scons: Fix source lists parsing on Windows.José Fonseca2013-01-231-2/+7
| | | | | | | | | | | / vs \ mismatch was causing .objs to be put in the source tree, causing breakeage when doing different build types in the same tree (eg., debug vs release). Fix this by normalizing everything to / slashes. It's probably a good idea to purge all .objs from source tree to prevent issues completely.

* draw: fix problem in screen-space interpolation clip codeBrian Paul2013-01-221-3/+3
| | | | | | | | | | | | | | | | | | I don't see how this could have ever worked right. The screen-space interpolation code uses the vertex->data[pos_attr] position which contain window coords. But window coords are only computed for the unclipped vertices; the clipped vertices have undefined window coords (see draw_cliptest_tmp.h). Use the vertex clip coords instead which are always defined.
