Linux外设分离-阿里云

Linux驱动的软件架构（三）：主机驱动与外设驱动分离的设计思想

《Linux设备驱动开发详解》的学习笔记1、主机驱动与外设驱动分离Linux中的SPI、I2C、USB等子系统都利用了典型的把主机驱动和外设驱动分离的想法，让主机端只负责产生总线上的传输波形，而外设端只是通过标准的API来让主机端以适当的波形访问自身。因此这里面就涉及了4个软件模块：1）主机端的驱动...

Linux主机驱动与外设驱动分离思想

- by 宋宝华(Barry Song) 1主机、外设驱动分离的意义在Linux设备驱动框架的设计中，除了有分层设计实现以外，还有分隔的思想。举一个简单的例子，假设我们要通过SPI总线访问某外设，在这个访问过程中，要通过操作CPU XXX上的SPI控制器的寄存器来达到访问SPI外设YYY的目的，最...
