Abstract

A method to logically serialize a plurality of independent system events in a virtual memory data processing system. Each event causes interrupt servicing routines to be executed and requires data structures that record the status of virtual pages to be updated. The system events include the interrupt that is generated as a result of a page fault, the interrupt that is generated as a result of a paging I/O completion operation that resolves a page fault, and lastly interrupts generated in response to a supervisory call to a paging service.
