Abstract

See full text

An address provided in a request issued by an adapter is converted to an address directly usable in accessing system memory. The address includes a plurality of bits, in which the plurality of bits includes a first portion of bits and a second portion of bits. The second portion of bits is used to index into one or more levels of address translation tables to perform the conversion, while the first portion of bits are ignored for the conversion. The first portion of bits are used to validate the address.
