The max chips and PMUs we'd be able to work out from the device tre though, right? We could just allocate the correct amount of memory on boot. We may hot plug/unplug CPUs, but we're not doing that from a hardware level, what CPUs you get in the DT on PowerNV on boot is all you're getting. -- Stewart Smith OPAL Architect, IBM.
