Abstract
A computing system includes a processor and a memory unit that stores program instructions. The system purges an entry from an address translation cache in response to the processor executing the program instructions to perform issuing, via an operating system running on the computing system, a command indicating a request to perform an I/O transaction requiring a translation entry. A host bridge monitors a total data length of the address translation entry to be transferred during the I/O transaction. An address translation entry is selected from an address translation table, loaded into the address translation cache, and data corresponding to the I/O transaction is transferred using the selected address translation entry. The host bridge automatically purges the selected address translation entry from the address translation cache in response to determining the transferred amount of data matches the total data length for the address translation entry.
