Yes, this is no problem -- you can run v4 applications on a v7 kernel just fine. > > b) For FP-heavy programs (e.g. ogg encoding), is it possible to > > build > > the packages with VFP/NEON but still get them to work in a soft > > FPU > > system?

The calling standard is actually compatible, so e.g. it's no problem to run an softfloat-compiled application with a library built for VFP and vice versa. _______________________________________________ fedora-arm mailing list fedora-arm@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-arm
