Updated and Optimized Ubuntu Free Graphics Drivers

[oibaf]

Updates

Mesa:

• Reverted to using default -O2 gcc optimization flag rather than previous -Os since it's faster on intel (thanks bongmaster2 for the performance tests!).
• Build with -fno-builtin-memcmp for increased performance (thanks curaga for suggesting it!). Eventually that should be added upstream.
• More r600g improvements.

Also included dri2proto 2.6, needed for newer xf86-video-intel.

There will be no more updates until the 18th, since I am going on vacation .

Updates

Mesa

• pipe-video branch is now officially merged on mesa master. libg3dvl-mesa package with nouveau (XvMC only), r300 and r600 (XvMC + VDPAU) hw drivers is again available (softpipe drivers now also supported). See this post for instructions on using it.
• Floating-point depth buffers.
• glsl-to-tgsi branch no longer included (due to merge conflicts).

Also included x11proto-gl 1.4.14, needed by current mesa.

Updates

Mesa
Added PP (Post Processing) branch. It actually includes Jimenez's MLAA and nocolor filters. Currently supported only with software rendering. To test:

LIBGL_ALWAYS_SOFTWARE=1 pp_jimenezmlaa=8 glxgears
LIBGL_ALWAYS_SOFTWARE=1 pp_nored=1 glxgears
LIBGL_ALWAYS_SOFTWARE=1 pp_nogreen=1 glxgears
LIBGL_ALWAYS_SOFTWARE=1 pp_noblue=1 glxgears

Multiple filters can be combined.

Ubuntu 11.04 install problems

I just installed the latest packages from this repo but (for the first time) got the following errors. Could it be related to the latest 280.04 nvidia drivers from the bumblebee PPA, https://launchpad.net/~mj-casalogic/+archive/bumblebee/ ? Any ideas would be greatly appreciated.

kde also turns of 3d desktop. kwin.

i think it runs software rendering mode...

but because why?

Renderer: Gallium 0.4 on amd rv730
OpenGL version: 2.1 Mesa 7.12-devel (git-b189d16 natty-oibaf-ppa+pp-branch)

There were some changes to winsys/radeon that may explain it.

I didn't noticed this post before. It is fixed now?

Updates

Mesa

• glsl-to-tgsi branch now officially merged into mesa master.
• PP filters should also work with hardware drivers. MLAA probably supported only on r600g.

Also, intel driver updated 2.15.901.

[curaga]

MLAA may or may not work even on r600g, see http://candgsoc.host56.com/2011/08/hw-binding/
