I think it's the combination of two things: * All Gallium drivers are linked into a single binary (so-called mega-driver) * SWR is compiled with AVX support and has initializers which are automatically executed when the above binary is dlopen()ed. Until there's a solution for this, SWR cannot be enabled in a build which has to run on non-AVX capable CPUs.
