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.
