HMP info mtree command reflects the flag with "nv-" prefix on memory type:
(qemu) info mtree
0000000100000000-000000013fffffff (prio 0, nv-i/o): alias nvdimm-memory
@/objects/mem1 0000000000000000-000000003fffffff
(qemu) info mtree -f
0000000100000000-000000013fffffff (prio 0, nv-ram): /objects/mem1
