[PATCH v4 00/40] target/arm: Implement ARMv8.1-VHE

Posted by Richard Henderson 1 week ago
Version 3 was posted back in August.  Though quite a lot has changed
and perhaps there's no use in comparing.  I haven't done a list.

Against master, it is the first version that can actually boot a
nested kernel under kvm, so that's certainly a change for the better.

It's not even particularly slow.  With both outer and nested kernel
using a minimal busybox initrd, the outer kernel boots in 4.0 seconds
and the nested kernel boots in 6.7 seconds.
