<H1>Mesa 7.5 Release Notes / date TBD</H1>
|

|
Mesa 7.5 is a new development release.
|
2009-04-07 18:23:21 -06:00
|
|
|
People who are concerned with stability and reliability should stick
|
|
|
|
|
with the 7.4.x branch or wait for Mesa 7.6.

The main new feature of Mesa 7.5 is the

<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.

|
|
|
|
<ul>
|
2009-04-07 18:23:21 -06:00
|
|
|
<li>Gallium - 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><a href="cell.html">Cell</a> - IBM/Sony/Toshiba Cell processor driver
|
|
|
|
|
<li>nouveau - preliminary driver for NVIDIA GPUs (still under development)
|
|
|
|
|
<li>r300 - preliminary driver for R300 (still under development)
|
|
|
|
|
</ul>
|
2009-01-22 15:51:12 -07:00
|
|
|
<li>GL_ARB_framebuffer_object extension (software drivers, i965 driver)
|
2009-01-23 11:36:57 -07:00
|
|
|
<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)
|
2009-01-28 15:06:54 -07:00
|
|
|
<li>GL_NV_texture_env_combine4 extension (software drivers, i965/i915 drivers)
|
|
|
|
|
<li>GL_EXT_texture_swizzle extension (software drivers, i965 driver)
|
2009-02-26 18:37:26 -07:00
|
|
|
<li>Updated SPARC assembly optimizations (David S. Miller)
|
