I am not sure if i have understood your point. What your suggestion is that
leave PMEM for hypervisor and all other parts (PBLK and _DSM handling) to
Dom0? If yes, we should:
a) handle hotplug in hypervisor (new PMEM add/remove) that causes hyperivsor
interpret ACPI SSDT/DSDT.
b) some _DSMs control PMEM so you should filter out these kind of _DSMs and
handle them in hypervisor.
c) hypervisor should mange PMEM resource pool and partition it to multiple
VMs.
