This field should be zero in our caseI'm not sure that it should be a zero, care to point source which tells that it should be zero?
The spec says that this is the Device Physical Address, so that it is the device internal address, it should be zero as we do not reserve any thing in device internal and we do not have no memory interleave. Actually, this bug was exported when we were enabling nvdimm in windows guest.
