17 Requester ID. While a given PCI device can only master through one IOMMU, a
18 root complex may split masters across a set of IOMMUs (e.g. with one IOMMU per

35 - iommu-map: Maps a Requester ID to an IOMMU and associated IOMMU specifier
39 (rid-base,iommu,iommu-base,length).
41 Any RID r in the interval [rid-base, rid-base + length) is associated with
42 the listed IOMMU, with the IOMMU specifier (r - rid-base + iommu-base).
44 - iommu-map-mask: A mask to be applied to each Requester ID prior to being
45 mapped to an IOMMU specifier per the iommu-map property.
