Design of a byte device of the driving program in linux system 系统下的字符设备驱动程序的设计
The most common types of device files are for block devices and character devices 大多数设备文件的类型是块设备和字符设备。
“ attack , ” however , some background information on character device management is necessary “攻击”前,需要了解一些字符设备管理的背景信息。
Accordance with the standards of linux char device driver program , this driver program provides some uniform api for software applications 驱动程序符合linux字符设备驱动程序的标准规范,屏蔽了硬件细节,为上层软件提供了标准的接口。
As some extended work , jffs , a flash based journaling file system , is added to the uclinux system , and drivers for some special character devices , buttons , are written 本文还介绍了对uclinux系统的扩展,包括实现日志型文件系统jffs和特殊的字符设备? ?按键的驱动。
Then , the thesis brings forward the hardware and software development platform for the agent . in the following part , the thesis designs the mibs that are required by the management of cable modem and the approach to realize of an extensible agent is given 在cablemodem的软硬件开发平台的基础上,给出了cablemodem网管代理实现的整体方案,特别针对mib的实现问题给出了解决办法,即设计和实现了虚拟字符设备驱动程序。
The software design section introduces the design of drivers used to complete the configuration of pm5366 and pm4329 . firstly , the software architecture of clinux os and the role of application software 、 os core and driver are expounded in the section 首先根据clinux操作系统软件的层次结构,介绍了应用程序、内核和驱动程序在整个软件体系中的角色和作用,然后具体描述了字符设备的驱动程序的设计流程,并详述了pm5366和pm4329驱动程序的实现。
Secondly , we implement a bpf model called mybpf on linux as a kernel module . it can collect packets within the netfilter frame , provide the applications with an interface in char device file manner and be attached to the nf _ ip _ pre _ routing hook defined by netfilter frame for ipv4 as a hook function . finally , we evaluate the performance between mybpf and other bpf on sock _ packet socket 该模块以字符设备文件的形式为应用程序提供接口,并在netfilter框架为ipv4定义的nf _ ip _ pre _ routing钩子上挂接了一个钩子函数,该钩子函数实现bpf虚拟机,完成对数据包的捕获;最后,本文对mybpf模块作了相应的测试并与在sock _ packet套接口上实现的bpf做了性能比较。
The focus is about the char device driver design used in the dvb receiving card and the drive development process in user space ; analyzing the dvb receiving system working principle and process under linux and providing a method to load the linux dvb receive card device drive into the linux kernel ; analyzing and implementing the firmware design of saa7146 chipset working with linux kernel and working characteristic in vrious working mode ; analyzing and implementing the frontend drive programing of the digital tv receive system ; realized the qam demodulation and the mpeg stream filter , so that the output stream can be used to playing on pc better . and this article designs an event management mechanism based on the mhp , which improve the linux dvb software system 重点研究了数字电视接收卡的字符设备驱动问题,阐述了用户空间开发驱动程序的过程;分析了linux下数字电视接收系统的工作原理和驱动程序开发过程,给出了linuxdvbapi接收卡设备驱动程序加载到linux内核中的方法;研究实现了saa7146芯片配合linux内核共同工作的固件设计和不同工作模式下的工作特性;研究实现了dvb接收系统中前端驱动程序的编写;设计实现了qam解调和mpeg流解复用,使输出传输流较好地用于pc播放;同时,本文所设计的一种符合mhp规范的中间件事件管理机制,优化了linuxdvb软件系统。
