The 3-bit source IDs in PCI configuration space registers, used to map devices to sockets, are limited to 8 unique IDs, and each ID is local to a UPI/QPI domain. Source IDs cannot be used to map devices to sockets on UV systems because they can exceed 8 sockets and have multiple UPI/QPI domains with identical, repeating source IDs. Use NUMA information to get package IDs instead of source IDs on UV systems, and use package/source IDs to name IMC information structures.
