在操作系统中，设备驱动程序负责管理硬件设备与操作系统之间的交互。随着现代计算机系统的复杂性不断增加，多个进程或线程可能同时访问同一个设备驱动，这就带来了并发控制的问题。并发控制是确保多个执行线程能够安全、有效地共享资源的关键技术。在设备驱动中，正确的并发控制机制不仅能够提高系统的性能和效率，还能保证系统的稳定性和可靠性。 4 | 5 | 设备驱动作为管理硬件资源的接口，往往和硬件对应，具有唯一性。而在应用层中，却可能多个线程同时访问和修改同一个设备驱动，可能会导致数据不一致的问题。此外数据竞争，也可能导致资源的错误使用和浪费。因此，在设备驱动中正确的实现并发控制机制是非常重要的。 6 | 7 | ## next_chapter 8 | 9 | [返回目录](../README.md) 10 | 11 | 直接开始下一节说明:

对于嵌入式平台软件开发来说，与纯粹软件的区别就是包含对于硬件的访问。在之前的驱动章节中，也展示了如何在应用层访问底层硬件，不过这里还是统一进行梳理说明，方便理解。对于嵌入式Linux应用来说，访问硬件的方式主要就有以下几种。 4 | 5 | 1. 在应用层以文件形式存在，使用标准文件接口(open/read/write/close/ioctl)访问即可；这里以字符类设备为主，也包含其它设备的配置功能。 6 | 2. 映射方式进行数据处理的设备，这类主要在配置的基础上，需要进行大量数据流的处理；这里主要是GUI界面和摄像头采集输入，需要使用额外的映射接口管理显示。 7 | 3. 网络通讯的形式访问设备，主要包含以太网、CAN通讯、WIFI模块、BLE模块等，这类设备在经过初始化和配置后，对于应用层就是socket通讯，使用socket接口即可访问。 8 | 4. 直接以文件目录的形式访问，主要包含闪存、U盘、固态硬盘等，在系统中虚拟成存储结构，直接支持文件和文件读、写、删除等。 9 | 10 | ## next_chapter 11 | 12 |
