Intel VT-d functionality, often referred to as an Intel VT-d Engine, has typically been
implemented at or near a PCI Express host bridge component of a computer system.
This might be in a chipset component or in the PCI Express functionality of a processor
with integrated I/O. When one such Intel VT-d engine receives a PCI Express
transaction from a PCI Express bus, it uses the B/D/F number associated with the
transaction to search for an Intel VT-d translation table. In doing so, it uses the B/D/F
number to traverse the data structure shown in the above figure. If it finds a valid
Intel VT-d table in this data structure, it uses that table to translate the address
provided on the PCI Express bus. If it does not find a valid translation table for a given
translation, this results in an Intel VT-d fault. If Intel VT-d translation is required, the
Intel VT-d engine performs an N-level table walk.
