Or, I mean, more easily it might be a problem with its special build root? AVX might be common nowadays, but not *that* much (especially considering all https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=mesa-git#n48 -- You are receiving this mail because: You are the QA Contact for the bug.

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. -- You are receiving this mail because: You are the assignee for the bug.
