Linux串口驱动程序(3)-打开设备

Linux串口驱动程序(3)-打开设备先来分析一下串口打开的过程： 1、用户调用open函数打开串口设备文件；2、在内核中通过tty子系统，把open操作层层传递到串口驱动程序中；3、在串口驱动程序中的xx_open最终实现这个操作。这里主要有2个点需要我们重点分析，一个是open函数的传递过程，而是串口驱动程序XXX_open函数的实现。 1.open函数传递打开uart_register_....

Linux串口（serial、uart）驱动程序设计

一、核心数据结构串口驱动有3个核心数据结构，它们都定义在1、uart_driveruart_driver包含了串口设备名、串口驱动名、主次设备号、串口控制台(可选)等信息，还封装了tty_driver(底层串口驱动无需关心tty_driver)。 struct uart_driver { struct module&nbs...
