Abstract

An input/output memory management unit (IOMMU) configured to control requests by an I/O device to a system memory includes control logic that may perform a two-level guest translation to translate an address associated with an I/O device-generated request using translation data stored in the system memory. The translation data includes a device table having a number of entries. The control logic may select the device table entry for a given request by the using a device identifier that corresponds to the I/O device that generates the request. The translation data may also include a first set of I/O page tables including a set of guest page tables and a set of nested page tables. The selected device table entry for the given request may include a pointer to the set of guest translation tables, and a last guest translation table includes a pointer to the set of nested page tables
