Congratulations! The upstreaming effort of a significant out-of-tree project like this often takes longer than expected, but several of you are already QEMU sub-maintainers so that will make it easier. Please consider submitting a KVM Forum (October 24-26 in Edinburgh, UK) presentation that highlights aspects of the architecture and how to emulate it in QEMU: https://events.linuxfoundation.org/events/kvm-forum-2018/ Stefan
