摘要
对Linux内核中的BottomHalf机制进行了详细描述,并从实现原理和实际使用两个方面对比,分析了从Linux2.0到最新的Linux2.6内核中所实现的BH函数接口、任务队列(TaskQueue)、Tasklet、软中断、工作队列(WorkQueues)等BottomHalf机制。
The Bottom Half mechanism in Linux kernel is expatiated detailedly in the paper. From the two aspects of realization theory and application, the Bottom Half mechanisms, such as BH function interface, task queue, tasktet, softirq, work queues, which evolve from Linux2.O to Linux2.6, are analyzed.
