Abstract

An interrupt signal is provided to an operating system executed using one or more processors of a plurality of processors. A bus attachment device receives an interrupt signal with an interrupt target ID identifying a processor assigned for use as a target processor for handling the interrupt signal. The bus attachment device translates the received interrupt target ID to a processor ID using an interrupt table entry and forwards the interrupt signal to the target processor for handling. The processor ID is used to address the target processor directly.
