6.5.2 Release Notes / (in progress)
</H1>
14 Mesa
6.5.2 is a
6.5 follow-on development release mostly consisting of
15 <a href=
"versions.html#6.5.1">bug fixes
</a>.
19 <h2>MD5 checksums
</h2>
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
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.
34 New features resulting from this work include:
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
43 <li>New Intel i965 DRI driver
44 <li>New
<code>minstall
</code> script to replace normal install program
45 <li>Faster fragment program execution in software
46 <li>Added (or fixed) support for
<a href=
"http://www.opengl.org/registry/specs/SGI/make_current_read.txt">
47 GLX_SGI_make_current_read
</a> to the following drivers:
</li>
54 <li>Added support for ARB_occlusion_query to the tdfx driver (Ian
60 <li>fixed invalid memory read while rendering textured points (bug
8320)
61 <li>fixed problems with freebsd-dri configuration (bug
8344)
62 <li>Mesa's fake glxGetCurrentContext() wasn't thread-aware
63 <li>OPTION NV_position_invariant didn't work in NV vertex programs
64 <li>glDrawPixels into a user-created framebuffer object could crash Xlib driver
65 <li>Line clipping was broken in some circumstances
66 <li>fragment.fogcoord register didn't always contain the correct value
67 <li>RGBA logicops didn't work reliably in some DRI drivers
68 <li>Fixed broken RGBA LogicOps in Intel DRI drivers
69 <li>Fixed some fragment program bugs in Intel i915 DRI driver
70 <li>Fixed glGetVertexAttribfvARB bug
8883
71 <li>Implemented glGetUniform[fi]vARB() functions
72 <li>Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug
9044)
73 <li>Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh)
74 <li>Fixed broken
"mgl" name mangling
75 <li>Indirect rending was broken for glMap* functions (bug
8899)
79 <h2>Internal code changes
</h2>
82 <li>The device driver functions ResizeBuffers and GetBufferSize have been
84 <li>OpenGL
2.0 and
2.1 support is nearly done. We need to do quite a bit
85 more testing of the shading language functions.
89 <h2>To Do (someday) items
</h2>
91 <li>Switch to freeglut
92 <li>Increase MAX_DRAWBUFFERS
93 <li>Fix linux-glide target/driver.
94 <li>Improved lambda and derivative calculation for frag progs.
