41 <li>New DRI memory manager system. Currently used by the i915tex driver.
42 Other DRI drivers will be updated to use the new memory manager in coming
45 To use the new driver you'll need the most recent DRM library and drivers
46 (version
2.2 or later) and a recent xf86-video-intel driver module from X.org.
48 New features resulting from this work include:
50 <li>EXT_framebuffer_objects, render to texture
51 <li>ARB_pixel_buffer_objects
52 <li>Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels
53 <li>Accelerated texture uploads from pixel buffer objects
54 <li>Potentially texturing directly from the pixel buffer object (zero
57 <li>New Intel i965 DRI driver
58 <li>New
<code>minstall
</code> script to replace normal install program
59 <li>Faster fragment program execution in software
60 <li>Added (or fixed) support for
<a href=
"http://www.opengl.org/registry/specs/SGI/make_current_read.txt">
61 GLX_SGI_make_current_read
</a> to the following drivers:
68 <li>Added support for ARB_occlusion_query to the tdfx driver (Ian
74 <li>fixed invalid memory read while rendering textured points (bug
8320)
75 <li>fixed problems with freebsd-dri configuration (bug
8344)
76 <li>Mesa's fake glxGetCurrentContext() wasn't thread-aware
77 <li>OPTION NV_position_invariant didn't work in NV vertex programs
78 <li>glDrawPixels into a user-created framebuffer object could crash Xlib driver
79 <li>Line clipping was broken in some circumstances
80 <li>fragment.fogcoord register didn't always contain the correct value
81 <li>RGBA logicops didn't work reliably in some DRI drivers
82 <li>Fixed broken RGBA LogicOps in Intel DRI drivers
83 <li>Fixed some fragment program bugs in Intel i915 DRI driver
84 <li>Fixed glGetVertexAttribfvARB bug
8883
85 <li>Implemented glGetUniform[fi]vARB() functions
86 <li>Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug
9044)
87 <li>Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh)
88 <li>Fixed broken
"mgl" name mangling
89 <li>Indirect rending was broken for glMap* functions (bug
8899)
93 <h2>Internal code changes
</h2>
96 <li>The device driver functions ResizeBuffers and GetBufferSize have been
98 <li>OpenGL
2.0 and
2.1 support is nearly done. We need to do quite a bit
99 more testing of the shading language functions.
103 <h2>To Do (someday) items
</h2>
105 <li>Switch to freeglut
106 <li>Increase MAX_DRAWBUFFERS
107 <li>Fix linux-glide target/driver.
108 <li>Improved lambda and derivative calculation for frag progs.
