Mesa 6.4 Release Notes
|
||||
|
||||
October 24, 2005
|
||||
|
||||
|
||||
|
||||
Introduction
|
||||
------------
|
||||
|
||||
Mesa uses an even/odd version number scheme like the Linux kernel.
|
||||
Odd numbered versions (such as 6.3) designate new developmental releases.
|
||||
Even numbered versions (such as 6.4) designate stable releases.
|
||||
|
||||
|
||||
6.4 is a bug-fix release. See the VERSIONS file for details.
|
||||
|
||||
|
||||
|
||||
GLUT tarball
|
||||
------------
|
||||
|
||||
Starting with 6.4, the GLUT library sources are distributed in a separate
|
||||
tarball. This was done at the request of Linux distro vendors who prefer
|
||||
to use freeglut.
|
||||
|
||||
|
||||
|
||||
|
||||
Driver Status
|
||||
---------------------- ----------------------
|
||||
DRI drivers varies with the driver
|
||||
XMesa (Xlib) implements OpenGL 1.5
|
||||
OSMesa (off-screen) implements OpenGL 1.5
|
||||
Windows/Win32 implements OpenGL 1.5
|
||||
Glide (3dfx Voodoo1/2) requires updates
|
||||
SVGA requires updates
|
||||
DJGPP requires updates
|
||||
GGI requires updates
|
||||
BeOS requires updates
|
||||
Allegro requires updates
|
||||
D3D requires updates
|
||||
|
||||
The drivers which require updates mostly need to be updated to work
|
||||
with the new gl_renderbuffer / gl_framebuffer infrastructure introduced
|
||||
in Mesa 6.3.

|
||||
New:
|

||||
- glxgears_fbconfig demo didn't work (bug 4237)
|
||||
- fixed bug when bilinear sampling 2d textures with borders
|
||||

|
||||

|
||||
- fixed precision problem in Z clearing (bug 4395)
|
||||
- glBitmap, glDraw/CopyPixels mistakenly generated selection hits
|
||||
- fixed potential segfault caused by reading pixels outside
|
||||
of renderbuffer bounds
|
||||
- glGetTexLevelParameter didn't accept GL_TEXTURE_DEPTH_SIZE_ARB
|
||||
- fixed memory corruption bug involving software alpha buffers
|
||||
- glReadPixels clipped by window bounds was sometimes broken
|
||||
- glDraw/CopyPixels of stencil data ignored the stencil write mask
|
||||
- glReadPixels from a texture bound to a framebuffer object didn't work
|
||||
- glIsRender/FramebufferEXT weren't totally correct
|
||||
- fixed a number of point size attenuation/fade bugs
|
||||
- fixed glFogCoord bug 4729
|
||||
- GLX encoding for transpose matrix functions was broken
|
||||
- fixed broken fragment program KIL and SWZ instructions
|
||||
- fragment programs that wrote result.depth.z didn't work
|
||||
|
||||
|
||||
6.5 month, day, 2005
|
||||
New:
|
||||
- GL_EXT_packed_depth_stencil extension
|
||||
- GL_EXT_timer_query extension
|
||||
- reflect demo improved to support multiple windows
|
||||
- singlebuffer demo (shows no/little-flicker single-buffered rendering)
|
||||
- r200: enable GL_ARB_texture_env_crossbar, separate the texture
|
||||
sampling unit bits from the texture env combine enable bits
|
||||
- GL_EXT_timer_query extension
|
||||
- r200: add support for GL_ATI_fragment_shader
|
||||
- added fast XOR-mode line drawing optimization
|
||||

<h2>1.5 How do I upgrade my DRI installation to use a new Mesa release?</h2>

<p>

You don't! A copy of the Mesa source code lives inside the XFree86/DRI source

tree and gets compiled into the individual DRI driver modules.

If you try to install Mesa over an XFree86/DRI installation, you'll lose
