I have worked extensively on PVH but didn't get time to work on that
specific feature, and more pressing stuff has keep appearing.
AMD posted an RFC series not long ago:
https://lore.kernel.org/xen-devel/20230312075455.450187-1-ray.huang@xxxxxxx/
That got quite a bit of feedback, we are currently waiting for an
updated version.
