| <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> |
| <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> |
| |
