Brian Paul60955d72006-09-21 22:51:16 +0000[diff] [blame]26<ul>
Brian Paul07bec142006-11-03 17:43:20 +0000[diff] [blame]27<li>New DRI memory manager system. Currently used by the i915tex driver.
28Other DRI drivers will be updated to use the new memory manager in coming
29months.
30<br>
31To use the new driver you'll need the most recent DRM library and drivers
32(version 2.2 or later) and a recent xf86-video-intel driver module from X.org.
33<br>
34New features resulting from this work include:
35<ul>
36<li>EXT_framebuffer_objects, render to texture
37<li>ARB_pixel_buffer_objects
38<li>Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels
39<li>Accelerated texture uploads from pixel buffer objects
40<li>Potentially texturing directly from the pixel buffer object (zero
41copy texturing).
42</ul>
43<li>New Intel i965 DRI driver
Brian Paul351feae2006-11-01 15:24:47 +0000[diff] [blame]44<li>New <code>minstall</code> script to replace normal install program
