Abstract:
The original Linux kernel is not a preemptible kernel.That limits the real-time capability of Linux.Based on the SMP support of Linux,the kernel of Linux can be made fully preemptible conveniently. This paper analyzes the principle of the preemptible kernel and compares two approaches to implement preemption.
摘要: Linux原有的内核是不可抢占的,这使得Linux不能很好地支持响应速度要求高的实时应用。利用Linux对SMP多处理器系统的支持,可以方便地将Linux内核改造为完全可抢占的。分析了Linux可抢占内核的实现原理,并对两种可抢占内核的实现方案作了比较。
