In other words, an FIQ is just a higher priority interrupt request, that is prioritized by disabling IRQ and other FIQ handlers during request servicing.
在换句话说,一个FIQ仅仅是一个更高优先级的中断请求时,由请求服务期间禁用IRQ和其他FIQ处理程序的优先级。
If high priority interrupts are not disabled during low priority interrupts, users must save the key registers in software during a low priority interrupt.
如果在响应低优先级中断时高优先级中断使能,用户必须在低优先级中断响应程序中保存那些关键的寄存器值。
These changes provide a fully preemptible kernel, threaded interrupt handlers, high-resolution timers, priority inheritance, and robust mutexes.
这些更改提供了完全抢占式内核、线程中断处理程序、高分辨率计时器、优先级继承和健壮的互斥锁(mutex)。
