its_set_affinity函数在irq-gic-v3-its.c:还会调用irq_data_update_effective_affinity设置活动affinity。代表当前是那个核来接受中断。 [root@localhost ~]# cat /proc/irq/57/smp_affinity_list 1,3,6 [root@localhost ~]# cat /proc/irq/57/effective_affinity_list 3 1. 2. 3. 4. 5....

The purpose of irqbalance is to distribute interrupts accross cpus in an smp system such that cache-domain affinity is maximized for each irq. In other words, irqbalance tries to assign irqs to cpu cores such that each irq stands a greater chance of having its interrupt handler be in cache...
