5.2.3.9. Process Address Space ID (PASID)

PASID is an optional feature that enables sharing of a single Endpoint device across multiple processes while providing each process a complete 64-bit virtual address space. In practice, this feature adds support for a TLP prefix that contains a 20-bit address space that can be added to memory transaction TLPs.
