[Mesa-users] OpenGL 3.2 with SWR?

When you configure with both llvmpipe (swrast) and swr, llvmpipe will be
the default.  To force OpenSWR to get used, set the GALLIUM_DRIVER=swr
environment variable.  For example:

[chuck.atkins at hal9000 ]$ glxinfo | grep "OpenGL renderer"
OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.7, 256 bits)
[chuck.atkins at hal9000 ]$ GALLIUM_DRIVER=swr glxinfo | grep "OpenGL renderer"
SWR detected AVX2
OpenGL renderer string: Gallium 0.4 on SWR

You can also adjust the number of threads used for rendering with the
KNOB_MAX_WORKER_THREADS variable or LP_NUM_THREADS for llvmpipe.
