<p>
|
||
|
|
Mesa 6.5.2 is a 6.5 follow-on development release with a few new features
|
||
|
|
but mostly consisting of bug fixes.
|
||
|

<h2>MD5 checksums</h2>
|
||
|
|
<pre>
|
||
|
|
TBD

<h2>New features</h2>
|
||
|
|
<ul>
|
||
|
|
<li>New DRI memory manager system. Currently used by the i915tex driver.
|
||
|
|
Other DRI drivers will be updated to use the new memory manager in coming
|
||
|
|
months.
|
||
|
|
<br>
|
||
|
|
To use the new driver you'll need the most recent DRM library and drivers
|
||
|
|
(version 2.2 or later) and a recent xf86-video-intel driver module from X.org.
|
||
|
|
<br>
|
||
|
|
New features resulting from this work include:
|
||
|
|
<ul>
|
||
|
|
<li>EXT_framebuffer_objects, render to texture
|
||
|
|
<li>ARB_pixel_buffer_objects
|
||
|
|
<li>Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels
|
||
|
|
<li>Accelerated texture uploads from pixel buffer objects
|
||
|
|
<li>Potentially texturing directly from the pixel buffer object (zero
|
||
|
|
copy texturing).
|
||
|
|
</ul>
|
||
|
|
<li>New Intel i965 DRI driver
|
||
|
|
<li>New <code>minstall</code> script to replace normal install program
|
||
|
|
<li>Faster fragment program execution in software
|
||
|
|
<li>Added (or fixed) support for <a href="http://www.opengl.org/registry/specs/SGI/make_current_read.txt">
|
||
|
|
GLX_SGI_make_current_read</a> to the following drivers:</li>
|
||

|
||
|
|
<li>tdfx</li>
|

</ul>
|
||
|
|
<li>Added support for ARB_occlusion_query to the tdfx driver (Ian
|
||
|
|
Romanick).</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|

<h2>Bug fixes</h2>
|
||
|
|
<ul>
|
||
|
|
<li>fixed invalid memory read while rendering textured points (bug 8320)
|
||
|
|
<li>fixed problems with freebsd-dri configuration (bug 8344)
|
||
|
|
<li>Mesa's fake glxGetCurrentContext() wasn't thread-aware
|
||
|
|
<li>OPTION NV_position_invariant didn't work in NV vertex programs
|
||
|
|
<li>glDrawPixels into a user-created framebuffer object could crash Xlib driver
|
||
|
|
<li>Line clipping was broken in some circumstances
|
||
|
|
<li>fragment.fogcoord register didn't always contain the correct value
|
||
|
|
<li>RGBA logicops didn't work reliably in some DRI drivers
|
||
|
|
<li>Fixed broken RGBA LogicOps in Intel DRI drivers
|
||
|
|
<li>Fixed some fragment program bugs in Intel i915 DRI driver
|
||
|
|
<li>Fixed glGetVertexAttribfvARB bug 8883
|
||
|
|
<li>Implemented glGetUniform[fi]vARB() functions
|
||
|
|
<li>Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug 9044)
|
||
|
|
<li>Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh)
|
||
|
|
<li>Fixed broken "mgl" name mangling
|
||
|
|
<li>Indirect rending was broken for glMap* functions (bug 8899)
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
|
||
|

<h2>Internal code changes</h2>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>The device driver functions ResizeBuffers and GetBufferSize have been
|
||
|
|
decprecated.
|
||
|
|
<li>OpenGL 2.0 and 2.1 support is nearly done. We need to do quite a bit
|
||
|
|
more testing of the shading language functions.
|
||
|
|
</ul>
|
||
|
|
|
||
|

|
<li>Increase MAX_DRAWBUFFERS
|
||
|
|
<li>Fix linux-glide target/driver.
|
||
|
|
<li>Improved lambda and derivative calculation for frag progs.
