Abstract
An I/O device operating according to a native computer architecture is accessed by a primary computer system operating according to a primary computer architecture. An application program of the primary computer system requests an I/O operation to access the I/O device. To facilitate this access, an application program interface formed of primary instructions for execution by the primary processor processes the I/O operation to provide an I/O request and to receive an interrupt in response to completion of the access. A thread is formed of primary instructions for execution by the primary processor for receiving the interrupt from the application program interface. A subsystem operates in response to the I/O request to access the I/O device and to provide the interrupt.
