Sorry, but this is all behind deep NDAs and is a custom (or not? maybe
microMIPS) solution in their MIPS core.
Xen does not support it and there is no real information on it anywhere.
Xen MIPS porting effort seems to be quite dead as Broadcom put it down
(somewhere around Xen 3.4) - and it was paravirtualization only.
They are using a proprietary microkernel if I read it correctly.
Here's a probable early paper on the tech - but it might've changed since.
