软中断

注意，每个CPU维持其自己的正常优先级和高优先级软中断矢量。

Note that each CPU maintains its own normal and high-priority softirq vectors .

通过软中断机制来调度微线程，当机器处于严重软件中断负荷之下时，可通过ksoftirqd（一种每CPU内核线程）软中断来调度。

Tasklets are scheduled through the softirq mechanism , sometimes through ksoftirqd ( a per-CPU kernel thread ), when the machine is under heavy soft-interrupt load .

软中断最初为具有32个软中断条目的矢量，用来支持一系列的软件中断特性。

Softirqs were originally designed as a vector of32 softirq entries supporting a variety of software interrupt behaviors .

虽然软中断还存在于内核中，推荐采用微线程和工作队列，而不是分配新的软中断矢量。

And although softirqs still exist in the kernel , tasklets and work queues are recommended instead of allocating new softirq vectors .
