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 for prerequisites

for DRI hardware acceleration.

New features

New, improved GLSL compiler written by Intel.

    See the  Shading Language 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.
