It seems like there should only be 4 nodes possible - 2 for sockets, 2 for host bridges. Unless I'm misunderstanding, it should be the case that a given physical address can only be hosted by 1 numa node (proximity domain). So it *should* be the case that you either have 4 nodes possible or 10 nodes possible, not 12. But I could be missing a piece of context. > Which command do we need for this info specifically?
