[Virtio-msg] Virtio-msg over FFA on Xen

Hi all,

I was wondering if the virtio-msg demos we have for FFA work on Xen? I have some vague memory that they do.

I wonder if I can use the same lower-level virtio-msg-bus or ffa calls to move messages between a DomU/Linux and a QEMU backend in Dom0?

Can someone point me to the code? Or documentation?

Thanks!

Best regards, Edgar
