| Brian Paul | 07bec14 | 2006-11-03 17:43:20 +0000 | [diff] [blame] | 27 | <li>New DRI memory manager system. Currently used by the i915tex driver. |
| 28 | Other DRI drivers will be updated to use the new memory manager in coming |
| 29 | months. |
| 30 | <br> |
| 31 | To 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> |
| 34 | New 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 |
| 41 | copy texturing). |
| 42 | </ul> |
| 43 | <li>New Intel i965 DRI driver |
| Brian Paul | 351feae | 2006-11-01 15:24:47 +0000 | [diff] [blame] | 44 | <li>New <code>minstall</code> script to replace normal install program |
