In order to thoroughly understand what makes Linux tick and why it works so well on a wide variety of systems, you need to delve deep into the heart of the kernel. The kernel handles all interactions between the CPU and the external world, and determines which programs will share processor time, in ...

内核超时等待机制的原理:
应用程序通过操作系统提供的系统调用接口获取资源时，在系统调用的入口参数里可以指定超时等待的最大时间，通常以毫秒为单位，内核会将其转化为系统的时钟（tick）

技术资料 rtthread的定时器管理源码分析
rt-thread的定时器的基本工作原理在RT-Thread定时器模块维护两个重要的全局变量，一个是当前系统的时间rt_tick（当硬件定时器中断来临时，它将加1），另一个是定时器链表rt_timer_list，系统中新创建的定时期都会被以排序的方式插入到rt_timer_list（硬件定时器模式下使用）链表中，rt_timer_list的每个节点保留了一个定时 ...
