Abstract

In one embodiment, a method is contemplated. An interrupt is received in a processor from an interrupt controller. Responsive to receiving the interrupt, the interrupt is masked in the interrupt controller to permit another interrupt to be transmitted by the interrupt controller to the processor. The other interrupt has a lower priority than the previously-received interrupt in the interrupt controller.
