ABSTRACT:
A system and method is provided to deliver messages to processors operating in a multi-processing environment. In a multi-processor environment, interrupts are managed by storing events in a queue that correspond to a particular support processor. A main processor decodes an interrupt and determines which support processor generated the interrupt. The main processor then determines whether a kernel or an application should process the interrupt. Interrupts such as page faults, segment faults, and alignment errors are handled by the kernel, while “informational” signals, such as stop and signal requests, halt requests, mailbox requests, and DMC tag complete requests are handled by the application. In addition, multiple identical events are maintained, and event data may be included in the interrupt using the invention described herein.
