Phoronix: R600 Gallium3D LLVM & SB Shader Back-End Tests

In recent months I have delivered a number of R600 SB shader optimization benchmarks for the AMD Gallium3D shader back-end that's part of Mesa 9.2. I've also delivered tests of the R600 LLVM back-end that's also been progressing in recent months and viewed as the future for AMD's open-source driver. This weekend are some independent tests of the R600 LLVM and SB back-ends...

Also having Catalyst there would be interesting.

Yep, I checked the latest catalyst comparison and it didn't have reaction quake results.

Those optimizations are part of 9.2 right??

Not enabled by default.

How can I enable this features in mesa 9.2?

You can choose sb+llvm backend by setting: export R600_DEBUG=sb

for just sb backend export R600_DEBUG=sb,nollvm

If you use KDE you can create file in /.kde4/env called for example export.sh then add to it export R600_DEBUG=<backend> and give executable right to it.

cheers

ps sorry for my english.

Thanks for the info
Luckily, I use KDE too.

Edit /etc/environment and put

R600_DEBUG=sb,nollvm

in it (without 'export'). This will set it system wide after reboot.

Thanks a lot for the info, but I have to ask: Why "nollvm"? Is there a reason for not to enable it?
