A processor receives interrupts of a same type from hardware. The processor determines a rate at which the interrupts are being received. The processor compares the rate at which the interrupts are being received to a threshold rate. In response to determining that the rate at which the interrupts are being received is greater than the threshold rate, the processor sends just the first received interrupt to firmware for processing. All other of the interrupts are not sent from the processor to the firmware but instead are suppressed by the processor. By comparison, in response to determining that the rate at which the interrupts are being received is less than the threshold rate, the processor can send all the interrupts from the processor to firmware for processing.
