* mesa: add EXT_texture_compression_latcMarek Olšák2011-03-081-0/+40
| | | | | | | | | | | | | | | | | 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/+41
| | | | | | | | | 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: fix mipmap generation for MESA_FORMAT_AL44Marek Olšák2011-02-161-1/+5
| | | | This was missed when implementing AL44.

* mesa/swrast: implement EXT_texture_sRGB_decodeDave Airlie2011-01-161-0/+37
| | | | | | | 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: do a debug check of _mesa_format_to_type_and_comps()Brian Paul2011-01-111-1/+23
| | | | | | | Make sure that all formats are handled in this function. It's easy to miss this function when adding new pixel formats. See also http://bugs.freedesktop.org/show_bug.cgi?id=31544
* mesa: fix a few format table mistakes, assertionsBrian Paul2011-01-111-7/+8
| | | | | | | The BaseFormat field was incorrect for a few R and RG formats. Fix a couple assertions too. NOTE: This is a candidate for the 7.9 and 7.10 branches.

* mesa: Assert format is not MESA_FORMAT_COUNT in _mesa_format_to_type_and_comps.Vinson Lee2010-12-231-1/+4
| | | | The case of format being MESA_FORMAT_COUNT should never occur.
* mesa: Fix #ifdef typo in _mesa_format_to_type_and_comps.Vinson Lee2010-12-231-1/+1
| | | | According to the comment, the warning should be for debug builds.

* mesa: implement new texture format AL44Marek Olšák2010-12-231-0/+10
| | | | | | 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/+14
| | | | Radeon GPUs do support GL_RGB10_A2.

* mesa: rename function to _mesa_is_format_integer_color()Brian Paul2010-10-261-1/+1
| | | | Be a bit more clear about its operation.
* mesa: fix bug in _mesa_is_format_integer()Brian Paul2010-10-261-2/+5
| | | | | | We only want to return true if it's an integer _color_ format, not a depth and/or stencil format. Fixes http://bugs.freedesktop.org/show_bug.cgi?id=31143
* mesa: _mesa_is_format_integer() functionBrian Paul2010-10-231-0/+12
|
* mesa: Fix misplaced #endifIan Romanick2010-10-011-1/+1
| | | | | If FEATURE_texture_s3tc is not defined, FXT1 formats would erroneously fall through to the MESA_FORMAT_RGBA_FLOAT32 case.
* ARB_texture_rg: Add R8, R16, RG88, and RG1616 internal formatsIan Romanick2010-10-011-0/+80
|
* mesa: include mfeatures.h in formats.cBrian Paul2010-09-161-0/+1
| | | | | Otherwise, FEATURE_EXT_texture_sRGB was undefined. This is (part of?) the fix for fd.o bug 30177.
* mesa: Use the format info to identify packed depth/stencil formats.Nick Bowler2010-08-271-6/+2
| | | | | | | | | | | Due to a misunderstanding of the Z24_X8 and X8_Z24 formats, the earlier patch created depth/stencil wrappers for them. This broke swrast. Use the format info instead, which only identifies Z24_S8 and S8_Z24 as packed depth/stencil. It also has the advantage of being nicer code.

* mesa: Identify packed depth/stencil buffers using the Format field.Nick Bowler2010-08-261-0/+16
| | | | | | | | | | | | | | | | | | | | Intel sometimes uses packed depth/stencil buffers even when only a depth buffer or only a stencil buffer was requested. Common code currently uses the _BaseFormat field to determine whether a depth/stencil wrapper is necessary. But unless the user explicitly requested a packed depth/stencil buffer, the _BaseFormat field does not encode this information, and the required wrappers are not created. The problem was introduced by commit 45e76d2665b38b ("mesa: remove a bunch of gl_renderbuffer fields"), which killed off the _ActualFormat field upon which the decision to create a wrapper used to be made. This patch changes the logic to use the Format field instead, which is more like the old code. Fixes fdo bug 27590.

| | | | | | 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.
