Abstract: Embodiments of an invention for address translation for scalable I/O device virtualization are disclosed. In one embodiment, an apparatus includes PASID table lookup circuitry. The PASID table lookup circuitry is to find a PASID-entry in a PASID table. The PASID-entry is to include a PASID processing mode (PPM) indicator and a first pointer to a first translation structure. The PPM indicator is to specify one of a plurality of translation types, the one of the plurality of translation types to use the first translation structure.
