Abstract

A system includes a plurality of partitions having respective operating systems, and a resource shared by the partitions. The resource has plural segments, where a first one of the segments is accessed to invoke a first interrupt. An operating system of a first one of the plurality of partitions invokes, in response to the first interrupt, a routine to cause generation of a second interrupt to a second one of the plurality of partitions.
