1.1硬件中断的定义: 硬件中断是由与系统相连的外设(如磁盘、网卡、键盘、时钟等)自动产生的异步信号。这些外设通过总线将中断信号发送给中断控制器,再由中断控制器转发给CPU。每个设备或设备集都有自己的中断请求(IRQ)号,基于这个IRQ号,CPU可以将相应的请求分发到对应的硬件驱动上。 每一个硬件都有自己的中断请求号...

这两个函数分别是disable、enable softirq,disable softirq后,当硬中断发生了,处理完硬中断后如果raise了softirq,此时不会wake ksoftirq/* thread来处理softirq。即在raise_softirq_irqoff()里会判断当前是否在interrupt context,这个in_interrupt()包括hardirq、softirq、nmi,如果先前有disable softirq,此时将判断得出是在in...
