Abstract
A method of operating a processing unit includes storing a first copy of a first interrupt control value in a cache device of the processing unit, receiving from an interrupt controller a first interrupt message transmitted via an interconnect fabric, where the first interrupt message includes a second copy of the first interrupt control value, and if the first copy matches the second copy, servicing an interrupt specified in the first interrupt message.
