2011-03-14mesa: rename _mesa_texstore_a8 -> _mesa_texstore_unorm8Marek Olšák
It's a generic function capable of storing A8, L8, I8, R8.
2011-03-08mesa: add EXT_texture_compression_latcMarek Olšák
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.
2011-02-28mesa: move PBO-related functions into a new fileBrian Paul
2011-02-28mesa: Add RGTC texture store/fetch support.Dave Airlie
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 <airlied@redhat.com>
2011-02-28mesa: make_float_temp_image non-staticDave Airlie
We need this to do signed stuff for RGTC.
2011-01-07mesa: Directly include mfeatures.h in files that perform feature tests.Vinson Lee
2011-01-05mesa: Include mtypes.h in files that use gl_context struct.Vinson Lee
Directly include mtypes.h if a file uses a gl_context struct. This allows future removal of headers that are not strictly necessary but indirectly include mtypes.h for a file.
2011-01-04mesa: preserve 10 bits of precision in the texstore general path for ARGB2101010Marek Olšák
Use make_temp_float_image instead of _make_temp_chan_image. The latter converts the texture to 8 bits/component, losing 2 bits.
2010-12-23mesa: implement new texture format I16Marek Olšák
2010-12-23mesa: implement new texture format L16Marek Olšák
2010-12-23mesa: implement new texture format A16Marek Olšák
2010-12-23mesa: implement new texture format AL44Marek Olšák
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.
2010-12-23mesa: implement new texture format ARGB2101010Marek Olšák
Radeon GPUs do support GL_RGB10_A2.
2010-11-16mesa: fix error messages and minor reindentingBrian Paul
2010-11-07mesa: implement uint texstore codeBrian Paul
We used float temporary images before which could lose precision for uint-valued texture images.
2010-10-28mesa: pixel transfer ops do not apply to integer-valued texturesBrian Paul
2010-10-28mesa: fix incorrect type in _mesa_texstore_rgba_int16()Brian Paul
2010-10-23mesa: split up the image.c fileBrian Paul
New files: pack.c - image/row packing/unpacking functions pixeltransfer.c - pixel scale/bias/lookup functions

2010-10-12mesa: remove assertion w/ undeclared variable texelBytesBrian Paul
2010-10-13mesa: improve texstore for 8/24 formats and add texstore for S8.Dave Airlie
this improves mesa texstore for 8/24 so it can create S24X8/X24S8 variants by keeping the depth bits static. it also adds a texstore for S8 so we can write out an S8 texture to use in the sampler for accel draw pixels to save memory bw. The logic seems sound here, I've worked it out a few times on paper, though it would be good to have some review. Signed-off-by: Dave Airlie <airlied@redhat.com>

More optional code.

2010-07-05mesa: initial support for unnormalized integer texture formatsBrian Paul
As defined by GL_EXT_texture_integer.
2010-05-09mesa: added unsigned 16-bit/channel tex formatBrian Paul

2010-02-19Replace the _mesa_*printf() wrappers with the plain libc versionsKristian Høgsberg
2010-02-19Replace _mesa_malloc, _mesa_calloc and _mesa_free with plain libc versionsKristian Høgsberg
2010-02-19mesa: replace old MEMCPY macro with memcpyBrian Paul
2010-02-19Remove _mesa_memcpy in favor of plain memcpy.Kenneth Graunke
This may break the SUNOS4 build, but it's no longer relevant.
2010-02-11main: Fix compiler warning. No need to convert/store depthScale as GLfloat ↵Karl Schultz
just to convert it back to GLuint to call unpack_depth_span. Also removes a difference between the 24/8 and 8/24 texstore routines.
2010-01-17mesa: Use preprocessor to comment out code.Vinson Lee
2009-12-02mesa: Fix bad conversion in AL1616_REV texstore.Eric Anholt
2009-11-17AL1616: Fix cut-and-paste bugIan Romanick
One of the PACK_COLOR_88 cases was left over from copying _mesa_texstore_al88 to _mesa_texstore_al1616.
2009-11-17Add MESA_FORMAT_XRGB8888_REV.Michel Dänzer
2009-11-16Move 'static' to start of declaration to silence compiler warningIan Romanick
2009-11-16AL1616: Add TexImage storage pathIan Romanick
2009-10-29mesa: fix _mesa_texstore_argb8888() for MESA_FORMAT_XRGB8888Brian Paul
If we hit the general path and call _mesa_make_temp_chan_image() we always want to get a GL_RGBA texture. We were getting a 3-channel GL_RGB texture before and that messed up the memory layout.

2009-10-25mesa: choose texture format in core mesa, not driversBrian Paul
Call the ctx->Driver.ChooseTextureFormat() function from core Mesa's _mesa_[Copy]TexImage functions instead of in the driver functions. One less thing for drivers to do.
