It may help to balance irq if the > irq workload of 3rd cpu is too heavy. I need the interrupts distribute over multiple cores, such as the second and third, so i set the mask parameter to 0x3. But only one core is handling the interrupts. As you can see, just the second cpu's irq number has increased. The irqbalance service has been stopped. -- Regards, Lenky -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
