Mesa 7.5 Release Notes / 17 July 2009
|
|
=====================================
|
|
|
|
Mesa 7.5 is a new development release. People who are concerned with
|
|
stability and reliability should stick with the 7.4.x branch or wait for
|
|
Mesa 7.5.1.
|
|
|
|
The main new feature of Mesa 7.5 is the
|
|
`Gallium3D <https://www.freedesktop.org/wiki/Software/gallium>`__
|
|
infrastructure.
|
|
|
|
Mesa 7.5 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 :doc:`Compiling/Installing page <../install>` for
|
|
prerequisites for DRI hardware acceleration.
|
|
|
|
Note that the Mesa project is no longer using odd/even version numbers
|
|
to indicate development/stable releases. The so-called development
|
|
releases have been fairly stable. If you're especially concerned with
|
|
stability you should probably look for "point" releases such as 7.5.1
|
|
which will be a bug-fix release.

New features
|
|
------------
|
|
|
|
- Gallium3D - this is the new architecture for OS-independent and
|
|
API-independent 3D drivers. Gallium3D is intended for GPUs that fully
|
|
support vertex/fragment shaders. The Gallium3D drivers currently
|
|
included are:
|
|
|
|
- softpipe - a software/reference driver
|
|
- i915 - Intel 915/945 driver
|
|
- Cell - IBM/Sony/Toshiba Cell processor driver
|
|
- nouveau (for NVIDIA GPUs) and R300 for (AMD/ATI R300).
|
|
|
|
.. note::
|
|
|
|
these drivers are incomplete and still under development.
|
|
It's probably NOT worthwhile to report any bugs unless you have
|
|
patches.
|
|
|
|
- GL_ARB_framebuffer_object extension (software drivers, i965 driver)
|
|
- Reworked two-sided stencil support. This allows a driver to support
|
|
all three variations of two-sided stencil including
|
|
GL_ATI_separate_stencil, GL_EXT_stencil_two_side and OpenGL 2.0
|
|
- GL_EXT_vertex_array_bgra extension (software drivers, i965 driver)
|
|
- GL_NV_texture_env_combine4 extension (software drivers, i965/i915
|
|
drivers)
|
|
- GL_EXT_texture_swizzle extension (software drivers, i965 driver)
|
|
- Updated SPARC assembly optimizations (David S. Miller)
|
|
- Initial support for separate compilation units in GLSL compiler.
|
|
- Increased max number of generic GLSL varying variables to 16
|
|
(formerly 8).
|
|
- GLSL linker now detects when too many varying variables are used.
|
|
- Optimize-out redundant glMaterial and glShadeModel calls in display
|
|
lists
|
|
- Fixed gl_TextureMatrix[i][j] array indexing bug in GLSL compiler.
|
|
|
|
Bug fixes
|
|
---------
|
|
|
|
- Lots of i965 driver bug fixes
|
|
- Fixed some GLSL preprocessor bugs
|
|
- GLSL: continue inside of a for-loop didn't work
|
|
|
|
Changes
|
|
-------
|
|
|
|
- Remove support for GL_SGIX_shadow, GL_SGIX_shadow_ambient and
|
|
GL_SGIX_depth_texture extensions. Superseded by the ARB versions.
|
|
- Omitted some old Mesa demos from the release tarballs, added some
|
|
others.
