* mesa/format: add mesa MESA_FORMAT_ARGB2101010_UINT support.Dave Airlie2011-11-281-0/+9
| | | | | | | | | | | | | | This format is used in the ARB_texture_rgb10_a2ui spec. It adds core mesa support, texformat + texstore support, format_unpack and fbobject.c (all patches from list merged + fixed up). also fixes some whitespace issues.

* mesa: Fall back to float16 if float32 isn't supported in ChooseTexFormat.Eric Anholt2011-11-221-0/+11
| | | | | | | Until GL 3.0, there isn't any requirement on the actual sizes of channels chosen. By falling back to 16 here, we can correctly support ARB_texture_float on original i965 hardware, which can't correctly filter 32-bit floats.
* mesa: Add fallback from RGB_FLOAT16 to RGBA_FLOAT16 before RGBA_FLOAT32.Eric Anholt2011-11-221-0/+1
| | | | | | | Not all i965 hardware can do RGB float16, and this will at least save half the memory and have expected behavior in terms of precision. Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>

| | | | | | | | | This fixes up the integer format choosing to pick the closest mesa format then the most likely fallback. (the formatting in this file needs cleaning in another patch). Signed-off-by: Dave Airlie <airlied@redhat.com>

* mesa: Remove EXT_bgra and EXT_texture_format_BGRA8888 extension enable flagsIan Romanick2011-09-261-1/+3
| | | | | | | | | | | | | All drivers remaining in Mesa support this extension. This extension is either required or optional features in desktop OpenGL, OpenGL ES 1.x, and OpenGL ES 2.x. EXT_texture_format_BGRA8888 is mostly a subset of EXT_bgra. The only difference seems to be that EXT_texture_format_BGRA8888 allows GL_BGRA as an internal format to glTexImage2D and friends.

| | | | | | | | | | | | | | EXT_shared_texture_palette This was also discussed at XDS 2010. However, actually making the change was delayed because several drivers still exposed these extensions to significant benefit (e.g., tdfx). Now that those drivers have been removed, this code can be removed as well. v2: A lot of bits that were missed in the previous patch have been removed.

* mesa: Remove all mention of MESA_FORMAT_CI8Ian Romanick2011-08-291-3/+0
| | | | | | | | | | | Nothing in Mesa supports color-index textures, and most of the other infrastructure that could allow such support has already been removed. This puts the final nail in the coffin. Also clean out some GL_COLOR_INDEX comments in formats.c. Reviewed-by: Brian Paul <brianp@vmware.com> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org>

| | | | | | | Also use MAX3 and incorporate Ian's suggestion in texformat.c. I don't think wrapping u_format_rgb9e5.h in another header and thus making it more complicated is worth it.

* mesa: Add fall-back formats for unsupported snorm formatsIan Romanick2011-04-041-3/+23
| | | | | | | | | | | | | | | | | | | | This is always the way with real hardware and desktop OpenGL. Some hardware can't do some formats natively. The alpha-only, luminance, and intensity formats are usually the most problematic. Some sized formats can also be problematic. This patch provides fall-back formats for those that are not natively supported. At some point it would be interesting to try providing device-independent conversions using EXT_texture_swizzle. The drivers that support EXT_texture_swizzle could, for example, see GL_LUMINANCE16_SNORM as MESA_FORMAT_SIGNED_R16 with a { r, r, r, 1 } swizzle. Care would need to be taken to prevent issues with using those textures for FBO rendering. This is the rest of the fix for glean's pixelFormats test on i965.

* mesa: add ATI_texture_compression_3dcMarek Olšák2011-03-081-0/+10
| | | | | | | LUMINANCE_ALPHA_LATC2 = LUMINANCE_ALPHA_3DC, so this is easy. Note that there is no specification for 3DC, just a few white papers from ATI.
* mesa: add EXT_texture_compression_latcMarek Olšák2011-03-081-0/+19
| | | | | | | | | | | | | | | | | 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.
