What I do for armv7 on aarch64 is to install an armv7 world into a directory tree and chroot into that world. As I understand jails also work. One can install armv7 ports and such in the alternate world. But I do not use X11 or other such so my range of experience is limited and there could be issues that I just do not know about. > As for running 32 bit kernels, I do not really have an opinion.
