<h1>Mesa 7.5 Release Notes / 17 July 2009</h1>
|
|
|
|
<p>
|
|
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.
|
|
</p>
|
|
<p>
|
|
The main new feature of Mesa 7.5 is the
|
|
<a href="http://wiki.freedesktop.org/wiki/Software/gallium">Gallium3D</a> infrastructure.
|
|
</p>
|
|
<p>
|
|
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.
|
|
</p>
|
|
<p>
|
|
See the <a href="../install.html">Compiling/Installing page</a> for prerequisites
|
|
for DRI hardware acceleration.
|
|
</p>
|
|
<p>
|
|
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.
|
|

<h2>New features</h2>
|
|
<ul>
|
|
<li>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:
|
|
<ul>
|
|
<li>softpipe - a software/reference driver
|
|
<li>i915 - Intel 915/945 driver
|
|
<li>Cell - IBM/Sony/Toshiba Cell processor driver
|
|
<li>nouveau (for NVIDIA GPUs) and R300 for (AMD/ATI R300).
|
|
<b>PLEASE NOTE: these drivers are incomplete and still under development.
|
|
It's probably NOT worthwhile to report any bugs unless you have patches.
|
|
</b>
|
|
</ul>
|
|
<li>GL_ARB_framebuffer_object extension (software drivers, i965 driver)
|
|
<li>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
|
|
<li>GL_EXT_vertex_array_bgra extension (software drivers, i965 driver)
|
|
<li>GL_NV_texture_env_combine4 extension (software drivers, i965/i915 drivers)
|
|
<li>GL_EXT_texture_swizzle extension (software drivers, i965 driver)
|
|
<li>Updated SPARC assembly optimizations (David S. Miller)
|
|
<li>Initial support for separate compilation units in GLSL compiler.
|
|
<li>Increased max number of generic GLSL varying variables to 16 (formerly 8).
|
|
<li>GLSL linker now detects when too many varying variables are used.
|
|
<li>Optimize-out redundant glMaterial and glShadeModel calls in display lists
|
|
<li>Fixed gl_TextureMatrix[i][j] array indexing bug in GLSL compiler.
|
|
</ul>
|
|
|
|
|
|
<h2>Bug fixes</h2>
|
|
<ul>
|
|
<li>Lots of i965 driver bug fixes
|
|
<li>Fixed some GLSL preprocessor bugs
|
|
<li>GLSL: continue inside of a for-loop didn't work
|
|
</ul>
|
|
|
|
|
|
<h2>Changes</h2>
|
|
<ul>
|
|
<li>Remove support for GL_SGIX_shadow, GL_SGIX_shadow_ambient and
|
|
GL_SGIX_depth_texture extensions. Superseded by the ARB versions.
|
|
<li>Omitted some old Mesa demos from the release tarballs, added some others.
|
|
</ul>
