Linux帧缓冲设备驱动原理和测试
Principle Of Frame Buffer Driver In Linux Kernel And Test
本文介绍了Linux内核的帧缓冲驱动原理，分析了帧缓冲驱动的基本数据结构和基本函数。数据结构的作用在于存放与显示设备相关的参数例如像素深度、屏幕宽度及高度。基本函数则提供了显示设备与内核空间之间的映射等操作。文末还给出了帧缓冲测试程序并结合帧缓冲原理分析了该测试程序。
his paper outlines the principle of frame buffer driver in Linux kernel, analyzes the basic data structures and functions in frame buffer framework. The data structures give space to hold the parameters of display such as pixel depth, screen width and height. The functions provide the operation like mapping the kernel space to display device. At the end of the paper, a frame buffer test program is introduced to illustrate the application of frame buffer.
