Description: 作者：华清远见嵌入式学院。《Linux设备驱动开发详解》（08&09年度畅销榜TOP50）第13章、Linux块设备驱动。块设备是与字符设备并列的概念，这两类设备在Linux中驱动的结构有较大差异，总体而言，块设备驱动比字符设备驱动要复杂得多，在I/O操作上表现出极大的不同，缓冲、I/O调度、请求队列等都是与块设备驱动相关的概念。本章将详细讲解Linux块设备驱动的编程方法。13.1节讲解块设备I/O操作的特点，分析字符设备与块设备在I/O操作上的差异。13.2节从整体上描述Linux块设备驱动的结构，分析主要的数据结构、函数及其关系。13.3～13.5节分别讲解块设备驱动模块加载与卸载、打开与释放和ioctl()函数。13.6节非常重要，讲述了块设备I/O操作所依赖的请求队列的概念及用法。13.2节与13.3～13.6节是整体与部分的关系，13.2～13.6节与13.7节是迭代递进的关系。13.7节在13.1～13.6节讲解内容的基础上，总结Linux下块设备的读写流程，而13.7节则讲解了块设备驱动的具体实例，即RamDisk的驱动。-Author: HuaQing vision embedded institute.

Piece of equipment is the concept of equipment and characters are, these two types of equipment in the structure of the drive in Linux have bigger difference, overall, piece of equipment than character device drivers drive is much more complex, in the I/O operation borrows great different, buffer, I/O operation, request queuing is of the device driver related concepts. This chapter will be explained Linux piece of equipment of the driver programming. Section 13.1 explain piece of equipment I/O operation, the characteristics of the character device and piece of equipment analysis in the I/O operation differences. Section 13.2 from the whole description of Linux device drivers, analysis of the main structure of the data structure, function and its relationship. 13.3 ~ 13.5 respectively of asher. Explain

Description: 海思Hi3520 PCI总线演示程序
PCIV 相关样例程序包含以下几部分：
1、PCIV MSG ：PCI业务层的消息通讯封装。基于MCC模块提供的ioctl接口，提供消息端口的打开关闭、消息发送、消息接收等接口。
相关代码为pciv_msg.c、pciv_msg.h。
2、PCIV Trans：PCI业务层的数据传输封装。基于PCI DMA传输接口、PCI消息交互及一套基本的读写指针Buffer，实现业务层通用数据传输接口。
可以用于主从片之间的任何类型的数据的传输。相关代码为pciv_trans.c、pciv_trans.h。
3、PCIV Sample：PCI业务层的接口使用样例。基于PCIV的MPI接口和以上两个模块提供的接口。
相关代码为sample_pciv_host.c、sample_pciv_slave.c、sample_pciv_comm.h。
目前演示的业务包括：
1）从片将实时预览图像通过PCI传输到主片并显示
2）从片将编码码流通过PCI传输到主片并存储
3）主片从文件中读取待解码码流，通过PCI传输到从片，从片解码后将图像数据再发送到主片显示。-Hass Hi3520 PCI bus demonstration program
PCIV relevant sample program contains the following sections:
1, PCIV MSG: PCI service layer message communication package. MCC module based on the ioctl interface to provide information to open the port closed, consumer
Information to send, the message receiver interfaces.
Related code pciv_msg.c, pciv_msg.h.
2, PCIV Trans: PCI data transfer package business layer. PCI DMA transfers based interface, PCI message exchange and a set of basic reading and writing pointers
Buffer, the business layer to achieve common data transfer interface.
Between master and slave chip can be used for any type of data transmission. Related code pciv_trans.c, pciv_trans.h.
3, PCIV Sample: PCI interface to use the business layer sample. Based on PCIV the MPI interface and the interface of these two modules.
Related code sample_pciv_host.c, sample_pciv_slave.c, sample_pciv_comm.h.

Description: This code shows a way to make a CD ripper in C#. There are APIs from some vendors that allow reading audio CD tracks but it is also possible to do it using APIs that allow low level access to CD drives such as ASPI from Adaptec or IOCTL control codes. The latter method is used in this case, because there is no need to install any third party software, it is completely covered by Win32 API functions (CreateFile, CloseHandle, DeviceIoControl, GetDriveType).

Description: linux上服务器的网卡驱动，内核编程，ioctl 驱动，ioctl是设备驱动程序中对设备的I/O通道进行管理的函数。所谓对I/O通道进行管理，就是对设备的一些特性进行控制，例如串口的传输波特率、马达的转速等等。
本代码是公司工程实际产品的驱动，极具参考价值。-linux on the server s network card drivers, kernel programming, ioctl driver, ioctl is device driver for the device I/O channel management functions. The so-called I/O channel management, some of the characteristics of the equipment is controlled, such as serial transmission baud rate, motor speed, and so on. The code is the actual product-driven engineering, great reference value.
