New features
|
|
------------
|
|
|
|
- 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.
|
|
|
|
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.
|
|
|
|
New features resulting from this work include:
|
|
|
|
- EXT_framebuffer_objects, render to texture
|
|
- ARB_pixel_buffer_objects
|
|
- Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels
|
|
- Accelerated texture uploads from pixel buffer objects
|
|
- Potentially texturing directly from the pixel buffer object (zero
|
|
copy texturing).
|
|
|
|
- New Intel i965 DRI driver
|
|
- New ``minstall`` script to replace normal install program
|
|
- Faster fragment program execution in software
|
|
- Added (or fixed) support for
|
|
`GLX_SGI_make_current_read <https://www.khronos.org/registry/OpenGL/extensions/SGI/GLX_SGI_make_current_read.txt>`__
|
|
to the following drivers:
|
|
|
|
- radeon
|
|
- savage
|
|
- mga
|
|
- tdfx
|
|
|
|
- Added support for ARB_occlusion_query to the tdfx driver (Ian
|
|
Romanick).
|
|
|
|
Bug fixes
|
|
---------
|
|
|
|
- fixed invalid memory read while rendering textured points (bug 8320)
|
|
- fixed problems with freebsd-dri configuration (bug 8344)
|
|
- Mesa's fake glxGetCurrentContext() wasn't thread-aware
|
|
- OPTION NV_position_invariant didn't work in NV vertex programs
|
|
- glDrawPixels into a user-created framebuffer object could crash Xlib
|
|
driver
|
|
- Line clipping was broken in some circumstances
|
|
- fragment.fogcoord register didn't always contain the correct value
|
|
- RGBA logicops didn't work reliably in some DRI drivers
|
|
- Fixed broken RGBA LogicOps in Intel DRI drivers
|
|
- Fixed some fragment program bugs in Intel i915 DRI driver
|
|
- Fixed glGetVertexAttribfvARB bug 8883
|
|
- Implemented glGetUniform[fi]vARB() functions
|
|
- Fixed glDrawPixels(GL_COLOR_INDEX, GL_BITMAP) segfault (bug 9044)
|
|
- Fixed some gluBuild2DMipmaps() bugs (Greg McGarragh)
|
|
- Fixed broken "mgl" name mangling
|
|
- Indirect rending was broken for glMap\* functions (bug 8899)
|
|
|
|
Internal code changes
|
|
---------------------
|
|
|
|
- The device driver functions ResizeBuffers and GetBufferSize have been
|
|
decprecated.
|
|
- OpenGL 2.0 and 2.1 support is nearly done. We need to do quite a bit
|
|
more testing of the shading language functions.
|
|
|
|
To Do (someday) items
|
|
---------------------
|
|
|
|
- Switch to freeglut
|
|
- Increase MAX_DRAWBUFFERS
|
|
- Fix linux-glide target/driver.
|
|
- Improved lambda and derivative calculation for frag progs.
