Mesa 7.9 Release Notes / October 4, 2010 ======================================== Mesa 7.9 is a new development release. People who are concerned with stability and reliability should stick with a previous release or wait for Mesa 7.9.1. Mesa 7.9 implements the OpenGL 2.1 API, but the version reported by glGetString(GL_VERSION) depends on the particular driver being used. Some drivers don't support all the features required in OpenGL 2.1. See the `Compiling/Installing page <../install.rst>`__ for prerequisites for DRI hardware acceleration.

See the `Shading Language <../shading.rst>`__ page for more information. - New, very experimental Gallium driver for R600-R700 Radeons. - Support for AMD Evergreen-based Radeons (HD 5xxx) - GL_EXT_timer_query extension (i965 driver and softpipe only) - GL_EXT_framebuffer_multisample extension (intel drivers, MAX_SAMPLES = 1) - GL_ARB_texture_swizzle extension (alias of GL_EXT_texture_swizzle) - GL_ARB_draw_elements_base_vertex, GL_ARB_fragment_program_shadow, GL_ARB_window_pos, GL_EXT_gpu_program_parameters, GL_ATI_texture_env_combine3, GL_MESA_pack_invert, and GL_OES_EGL_image extensions in Gallium drivers - GL_ARB_depth_clamp and GL_NV_depth_clamp extensions (in nv50 and r600 Gallium drivers) - GL_ARB_half_float_vertex extension (in nvfx, r300, r600, softpipe, and llvmpipe Gallium drivers) - GL_EXT_draw_buffers2 (in nv50, r600, softpipe, and llvmpipe Gallium drivers) - GL_EXT_texture_swizzle (in nvfx, r300, r600, softpipe, and llvmpipe Gallium drivers) - GL_ATI_texture_mirror_once (in nvfx, nv50, r300, r600, softpipe, and llvmpipe Gallium drivers) - GL_NV_conditional_render (in r300 Gallium driver) - Initial "signs of life" support for Sandybridge hardware in i965 DRI driver. Bug fixes --------- This list is likely incomplete. - Massive improvements to the Gallium driver for R300-R500 Radeons; this driver is now considered stable for use as a DRI (OpenGL) driver. - `Bug 10908 `__ - GLSL: gl_FogParamaters gl_Fog built-in uniform not functioning - `Bug 13753 `__ - Numerous bugs in GLSL uniform handling - `Bug 16854 `__ - GLSL function call at global scope causes SEGV - `Bug 16856 `__ - GLSL indexing of unsized array results in assertion failure - `Bug 18659 `__ - Crash in shader/slang/slang_codegen.c \_slang_gen_function_call_name() - `Bug 19089 `__ - [GLSL] glsl1/shadow2D() cases fail - `Bug 22622 `__ - [GM965 GLSL] noise*() cause GPU lockup - `Bug 23743 `__ - For loop from 0 to 0 not optimized out - `Bug 24553 `__ - shader compilation times explode when using more () pairs - `Bug 25664 `__ - [GLSL] re-declaring an empty array fails to compile - `Bug 25769 `__ - [GLSL] "float" can be implicitly converted to "int" - `Bug 25808 `__ - [GLSL] const variable is modified successfully - `Bug 25826 `__ - [GLSL] declaring an unsized array then re-declaring with a size fails - `Bug 25827 `__ - [GLSL] vector constructor accepts too many arguments successfully - `Bug 25829 `__ - [GLSL] allowing non-void function without returning value - `Bug 25830 `__ - [GLSL] allowing non-constant-expression as const declaration initializer - `Bug 25877 `__ - [GLSL 1.10] implicit conversion from "int" to "float" should not be allowed - `Bug 25878 `__ - [GLSL] sampler is converted to int successfully - `Bug 25994 `__ - [GM45][GLSL] 'return' statement in vertex shader unsupported - `Bug 25999 `__ - [GLSL] embedded structure constructor fails to compile - `Bug 26000 `__ - [GLSL] allowing different parameter qualifier between the function definition and declaration - `Bug 26001 `__ - [GLSL 1.10] constructing matrix from matrix succeeds - `Bug 26224 `__ - [GLSL] Cannot get location of a uniform struct member - `Bug 26990 `__ - [GLSL] variable declaration in "while" fails to compile - `Bug 27004 `__ - [GLSL] allowing macro redefinition - `Bug 27060 `__ - [965] piglit glsl-fs-raytrace failure due to lack of function calls. - `Bug 27216 `__ - Assignment with a function call in an if statement causes an assertion failure - `Bug 27261 `__ - GLSL Compiler fails on the following vertex shader - `Bug 27265 `__ - GLSL Compiler doesnt link the attached vertex shader - `Bug 27388 `__ - [i965] piglit glsl-vs-arrays failure - `Bug 27403 `__ - GLSL struct causing "Invalid src register file ..." error - `Bug 27914 `__ - GLSL compiler uses MUL+ADD where it could use MAD - `Bug 28055 `__ - glsl-texcoord-array fails GLSL compilation - `Bug 28374 `__ - SIGSEGV shader/slang/slang_typeinfo.c:534 - `Bug 28748 `__ - [i965] uninlined function calls support - `Bug 28833 `__ - piglit/shaders/glsl-texcoord-array fail - `Bug 28834 `__ - Add support for system fpclassify to GL_OES_query_matrix function for OpenBSD / NetBSD - `Bug 28837 `__ - varying vec4 index support - `Bug 28845 `__ - The GLU tesselator code has some warnings - `Bug 28889 `__ - [regression] wine game crash - `Bug 28894 `__ - slang build fails if absolute path contains spaces - `Bug 28913 `__ - [GLSL] allowing two version statements - `Bug 28931 `__ - Floating Point Exception in Warzone2100 Trunk version - `Bug 28966 `__ - [r300g] Dynamic branching 3 demo does not run - `Bug 28967 `__ - slang/slang_emit.c:350: storage_to_src_reg: Assertion \`index >= 0' failed. - `Bug 29013 `__ - [r300g] translate_rgb_op: unknown opcode ILLEGAL OPCODE - `Bug 29020 `__ - [r300g] Wine d3d9 tests hardlock - `Bug 29910 `__ - Mesa advertises bogus GL_ARB_shading_language_120 - `Bug 30196 `__ - [GLSL] gl_TextureMatrix{Inverse,Transpose,InverseTranspose} unsupported Changes ------- - The Mesa demo/test programs have been moved into a separate git repository. - GL/glext.h file upgraded to version 64 - GL/glxext.h file upgraded to version 32 - GL/wglext.h file upgraded to version 22
