ABSTRACT:
A method for processing an interrupt message in a system having a plurality of processors arranged into at least two partitions. The interrupt message is decoded to identify an interrupt source. If the interrupt source is not in an interrupt set, the interrupt is dropped. If the interrupt source is in a local partition, the interrupt is delivered. If the interrupt source is in the interrupt set and not in the local partition, the interrupt is processed in accordance with at least one of a target enable register and a vector enable register.
