Hafnium is a hypervisor, initially supporting aarch64 (64-bit Armv8 CPUs).

Development is no longer hosted here, as it has been donated to the Trusted Firmware project hosted by Linaro. Please see the new git repository, project page and bug dashboard instead.

This repository is kept for historical reference, but no new changes will be accepted here.
