* mesa: add R/RG floating-point formatsMarek Olšák2011-04-151-0/+28

* mesa: move sampler state into new gl_sampler_object typeBrian Paul2011-04-101-1/+1
| | | | | | 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: implement texstore and texfetch hooks for signed normalized formatsMarek Olšák2011-03-291-15/+71
| | | | | | The snorm texstore functions were all broken. swrast support done except for mipmap generation, but I leave it disabled.
* mesa: add EXT_texture_compression_latcMarek Olšák2011-03-081-0/+28
| | | | | | | | | | | | | | | | | The encoding/decoding algorithms are shared with RGTC. Thanks to some magic with the base format, the RGTC texstore functions work for LATC too. swrast passes the related piglit tests besides two things: - The alpha channel is wrong (it's always 1), however the incorrect alpha channel makes some other tests fail too, so I guess it's unrelated to LATC. - Signed LATC fetches aren't correct yet (signed values are clamped to [0,1]), however RGTC has the same problem. Further testing (with other of my patches) shows that hardware drivers and softpipe work. BTW, ETQW uses this extension.
* mesa: Add RGTC texture store/fetch support.Dave Airlie2011-02-281-1/+30
| | | | | | | | | This adds support for the RGTC unsigned and signed texture storage and fetch methods. the code is a port of the DXT5 alpha compression code. Signed-off-by: Dave Airlie <[email protected]>

* mesa/swrast: implement EXT_texture_sRGB_decodeDave Airlie2011-01-161-1/+24
| | | | | | | This implements the extension by choosing a different set of texture fetch functions when the texture parameter changes. Signed-off-by: Dave Airlie <[email protected]>
* mesa/swrast: handle sRGB FBOs correctly (v2)Dave Airlie2011-01-111-1/+1
| | | | | | | | | | | | | | | | From reading EXT_texture_sRGB and EXT_framebuffer_sRGB and interactions with FBO I've found that swrast is converting the sRGB values to linear for blending when an sRGB texture is bound as an FBO. According to the spec and further explained in the framebuffer_sRGB spec this behaviour is not required unless the GL_FRAMEBUFFER_SRGB is enabled and the Visual/config exposes GL_FRAMEBUFFER_SRGB_CAPABLE_EXT. This patch fixes swrast to use a separate Fetch call for FBOs bound to SRGB and avoid the conversions. v2: export _mesa_get_texture_dimensions as per Brian's comments.

* mesa: implement new texture format AL44Marek Olšák2010-12-231-0/+7
| | | | | | Radeon GPUs can do this. R600 can even do render-to-texture. Packing and extracting aren't implemented, but we shouldn't hit them (I think). Tested with swrast, softpipe, and r300g.
* mesa: implement new texture format ARGB2101010Marek Olšák2010-12-231-0/+7
| | | | Radeon GPUs do support GL_RGB10_A2.
* mesa: pass gl_format to _mesa_init_teximage_fields()Brian Paul2010-11-181-9/+3
| | | | | | | | | | | This should prevent the field going unset in the future. See bug http://bugs.freedesktop.org/show_bug.cgi?id=31544 for background. Also remove unneeded calls to clear_teximage_fields(). Finally, call _mesa_set_fetch_functions() from the _mesa_init_teximage_fields() function so callers have one less thing to worry about.

* mesa: added MESA_FORMAT_X8_Z24 formatBrian Paul2009-10-211-0/+7
| | | | | | 24-bit Z in 32-bit pixel. We could probably use the MESA_FORMAT_S8_Z24 format but this there's a few places where we explicitly don't want stencil. This format may go away at some point in the future.
