2010-04-09util: Fix typo in earlier commit.José Fonseca
2010-04-09util: ubyte_to_float and float_to_ubyte whenever possible.José Fonseca
More accurate results. We should probably generalize these functions for more cases.
2010-04-09util: Get all depth stencil tests passing.José Fonseca
Note the tests don't test all the paths, in particular stride, and ensuring the old value is preserved.
2010-04-09util: Add missing break statement.José Fonseca
2010-04-09util: Use consistent symbols in pack generator.José Fonseca
2010-04-09util: Reorder format tests -- group by format.José Fonseca
2010-04-09util: Add dedicated depth-stencil packing/unpacking functions.José Fonseca
Depth-stencil manually written given that each one is very close to be a special case. u_format_zs.c's still untested.
2010-04-09util: Include u_debug for debug_print_format.Corbin Simpson
Caused fun linker errors on r600g.

2010-04-08util: Support PIPE_FORMAT_B4G4R4X4_UNORM and PIPE_FORMAT_R8G8B8X8_UNORM.José Fonseca
2010-04-08util: (Almost) universal format translation function.José Fonseca
Untested.
2010-04-08util: Describe, implement, and test the new D3D9 color formats.José Fonseca
2010-04-08util: is_array/mixed/etc is only meaningful for plain formats.José Fonseca
2010-04-08util: Keep const keyword when unpacking formats.José Fonseca
2010-04-08util: Reorder the code generated function so that they are grouped by format.José Fonseca
Makes it easier to copy and paste.
2010-04-08util: Don't call util_dl_close(library) when util_format_s3tc_init is ↵José Fonseca
successful." Otherwise the library will be unloaded and function pointers become invalid. This reverts commit bc2bc0306e4dd8c56bd66a8aabf2433f6689653d.
2010-04-08util: util_dl_close(library) before exiting util_format_s3tc_init.Vinson Lee
2010-04-07util: Support fixed formats conversion.José Fonseca
2010-04-07util: Add copyright header to u_half.hJosé Fonseca
2010-04-07util: Remove the half typedef from p_compiler.h.José Fonseca
Unnecessary, and doesn't even guarantee size.
2010-04-07util: Use stubs for the dynamically loaded S3TC functions.José Fonseca
Loosely based on Luca Barbieri's commit 52e9b990a192a9329006d5f7dd2ac222effea5a5.
2010-04-07util: Remove u_tile.c YCbCr's.José Fonseca
Superseded by u_format_yuv.c. Also PIPE_FORMAT_YUYV's interpretation was inconsistent: it was being interpreted as VYUY.
2010-04-07util: Implement YUV and subsampled RGB format conversion.José Fonseca
2010-04-06util: Respect destination stride in pipe_get_tile_swizzle().Michal Krol
2010-04-06util: Make half float lookup tables constant.José Fonseca
2010-04-06util: Remove the hand written SRGB format support code.José Fonseca
2010-04-06util: Support all SRGB formats.José Fonseca
Based on code from Brian Paul and Michal Krol.
2010-04-05util: added util_dl_error()Brian Paul
2010-04-04Merge branch '7.8'Ian Romanick
2010-04-03util: Use GCC atomic bultins on GCC 4.1 and higher only.Vinson Lee
2010-04-03util: Revert unsolicited, untested, unreviewed, and broken changes to format ↵José Fonseca
support. Not all is bad, but I'm afraid I'll have to throw the baby with the water given they are all tied to together.
2010-04-02gallium/util: print \n after DXTn printfLuca Barbieri
2010-04-01gallium/util: remove extraneous semicolonBrian Paul
2010-04-02gallium/util: revert util_format_init additionLuca Barbieri
Putting calls to util_format_init all over the codebase is infeasible. Instead, half float tables are pregenerated, and the s3tc library is loaded on demand. I believe this is a solution that combines performance, cleanliness, flexibility and portability.
2010-04-02gallium/util: add util_format_is_supported to check for pack/unpackLuca Barbieri
This improves the code by making it more readable, and removes special knowledge of S3TC and other formats from softpipe.
2010-04-02gallium/util: load s3tc on demandLuca Barbieri
This changes the S3TC function pointers to be initialized to stubs that load the S3TC library and then delegate to the real functions. If the S3TC library fails to load, the function pointers are replaced with a "nop" function. The code is also changed to attempt to load the library only one time.c Note that unlike checking for a flag, this method has no performance cost at all. The use of the "nop" functions also allows to avoid most checks, that are only preserved when the function does non-trivial work.
2010-04-02gallium/util: pregenerate half float tablesLuca Barbieri
This solution avoids the issue of how to run the initializers and also allows those pages (and the parts of them in processor caches) to be shared between multiple processes. The drawback is slightly higher library size.
2010-04-01gallium/util: s/inline/INLINE/Vinson Lee
Fixes MSVC build.
2010-04-02gallium/util: add util_format_init that inits s3tc and util_halfLuca Barbieri
Switch from auto-init to explicit init for util_half per Brian Paul's indication. NOTE: this is probably broken because not enough things call util_format_init. Will be fixed shortly
2010-04-02gallium/util: add one-time initialization helperLuca Barbieri
2010-04-02gallium/util: use #pragma section instead of #pragma data_segLuca Barbieri
They apparently both declare the section, but #pragma data_seg also puts all subsequent definitions in the section, which is undesirable. This should be the correct solution, and is actually used by the reference I cited (but I forgot to do it in my code). Untested, let me know if it doesn't work.
2010-04-02gallium/util: reindent u_half.c and u_half.h with Mesa coding styleLuca Barbieri
Sorry, forgout about that.
2010-04-02Revert "util: Init half-float tables on demand."Luca Barbieri
This reverts commit 950300eb255f0e3507bf2757d16c3b5bc8ff3471.
2010-04-01util: Init half-float tables on demand.Corbin Simpson
Gets rid of unnecessary delays on startup and compiler-specific hax.
2010-04-01util: Declare .CRT$XCU data segment.Michal Krol
2010-04-01gallium/util: rewrite global constructor system for half floats (GCC/MSVC only!)Luca Barbieri
NOTE: this commit will cause Gallium to fail to build on any compiler except GCC, the Microsoft C compiler and compatible compilers that claim to be one of those. This commit removes the u_gctors.cpp mechanism, in favor of using compiler-specific syntax to add global constructors from C files. This solves the problem of u_gctors.o not being pulled from static libraries and avoids using C++. However, it needs compiler-specific support for every compiler. The Microsoft C compiler support has not been tested.
2010-04-01gallium/util: add copyright header to u_half.cLuca Barbieri
2010-04-01util: Declare util_half_init_tables only once.José Fonseca
2010-04-01util: Use u_math.h's union fi instead of redefining it.José Fonseca
2010-04-01util: Add support for other DXTn RGBA formats.José Fonseca
