Abstract
Interrupts are directed to currently idle processors. Which of a number of processors of a computing system that are currently idle is determined. An interrupt is received and directed to one of the currently idle processors for processing. Determining which processors are currently idle can be accomplished by monitoring each processor to determine whether it has entered an idle state. When a processor has entered an idle state, it is thus determined that the processor is currently idle. Where just one processor is currently idle, an interrupt is directed to this processor. Where more than one processor is currently idle, one of these processors is selected to which to deliver an interrupt, such as in a round-robin manner. Where no processor is currently idle, then one of the processors is selected to which to deliver an interrupt.
