Linux驱动开发（锁和信号量的概念及实现原理）

前言本篇文章我们来讲解锁的概念和实现原理。一、锁的概念在Linux中，锁（Lock）是一种同步机制，用于保护共享资源或临界区免受并发访问的影响。它可以确保在任何给定时间只有一个线程可以访问共享资源，从而防止竞争条件（Race Condition）和数据不一致的问题。锁的主要目的是用于协调并发执行的线程，以确保资源的正确访问顺序和数据的一致性。当一个线程需要访问共享资源时，它必须先获得锁，执行完对....

Linux驱动开发——并发和竞态（概念介绍①）

文章目录Linux内核并发和竞态案例一：案例二：分析相关概念Linux内核解决竞态引起的异常（漏洞）的方法Linux内核并发和竞态案例一：前面就发现了在Linux内核中使用全局变量或者多线程可能同时访问的区域会遇到竞态的问题，比如前面的定时器使用的实现部分就发生了并发问题。Linux驱动开发——定时器造成这样的原因是因为当我们按下按键的时候会操作多次按键中断触发，而在按键中断处理函数中会对一个全....
