Gallium3D / LLVMpipe With LLVM 2.8

[marek]

Starcraft or Starcraft 2?

The former should work everywhere. The latter works e.g. with the R300 Gallium3D driver (r300g) to some extent. No idea about the other drivers. We got 2 bug reports against r300g running Starcraft 2 and we have fixed both.

to have smooth SC 1 i need to use FGLRX + change from GDI to OPENGL in wine setting, both works slow on opendrivers:<

SC 2 doesent even work, on both drivers

i have radeon 4850 [r700]

i really want to get rid of close source drivers :<

Mesa must be compiled with the parameter --enable-gallium-llvm to get the LLVM-compiled vertex shaders in Gallium.

llvmpipe is definitely slower (about 10 times) unless you do a lot of data moves between RAM and VRAM.

I checkout mesa repository, and configure/compile it:

git clone git://anongit.freedesktop.org/git/mesa/mesa
cd mesa
./autogen.sh
./configure --enable-glx-tls --with-dri-drivers= --enable-gallium-llvm --disable-gallium-nouveau --disable-gallium-i915 --disable-gallium-i965 --enable-gallium-radeon --enable-gallium-r600 --disable-gallium-svga --with-state-trackers=glx,dri
make -j 2

then I copied various libs from the ./mesa/lib/gallium overwriting the system lib. Restart the computer and run xbmc again. Only a very marginal improvement, 16-18fps over r300g 5 months ago. Maybe, r300g llvm usage for vertex shader is not included in the main mesa tree?

I meant I got 16-18fps instead of 15fps (5 months ago, before llvm vertex shader was included). I remember with the old fglrx, I used to get 90fps.

FWIW I don't think you need --enable-gallium-r600. It won't cause any problems, but you'll probably build faster and have fewer chances of picking up the wrong file if you omit it.
