Corruption has again been reported on Intel hardware running Xorg with the modesetting driver (which uses OpenGL based acceleration instead of SNA acceleration the intel driver defaults to). Reported in various forms on Sandy Bridge (X220), Ivy Bridge (X230) and Haswell (X240). Confirmed to not occur with the intel driver but the xserver was changed to default to the modesetting driver on >= gen4 hardware (except Ironlake). One means of triggering this is to open a large pdf with xpdf on an idle machine and highlight a section of the document. There have been reports of gpu hangs on gen4 intel hardware (T500 with GM45, X61 with 965GM) when starting Xorg as well.

<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:
|
|
<ul>
|
|
<li>radeon</li>
|
|
<li>savage</li>
|
|
<li>mga</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>
|
|
|
|
|
|
<h2>To Do (someday) items</h2>
|
|
<ul>
|
|
<li>Switch to freeglut
|
|
<li>Increase MAX_DRAWBUFFERS
|
|
<li>Fix linux-glide target/driver.
|
|
<li>Improved lambda and derivative calculation for frag progs.
|
|
</ul>
