It's been a long time! Write something. about the implementation of the keyboard driver in Linux 2.6.2.6 The kernel adopts the "input sub system" concept and divides the input driver into three parts: Driver, input core, and event handler."An input

Linux input device is an important subsystem. Before introducing the example, let's take a look at the related APIs. Linux Input Device Input. c is the "input" notebook program of Linux, which mainly supports loading and mouse loading. input. the

[Size = 4] interaction between Linux User and Kernel-- Netlink [/size] Author: Kendo2006-9-3 This is a learning note, mainly for the implementation and analysis of the source code imp2 in Linux kernel space and user space communication. The source

Installing Linux is the first threshold for beginners. In this process, the biggest confusion is to partition the hard disk. Although Linux of various Release versions already provides a friendly graphic interaction interface, many people still feel

Based on the original author's analysis on linux2.4.0, the author's current kernel is 2.6.32. I will mark the difference in red as a supplement to the original article.   This article mainly analyzes the Linux2.4.0 implementation principle of IO

[What is framebuffer] Frame Buffer. Frame: the image of the screen you see, or the image in a window, is called a frame. Buffer: A piece of RAM used to store image data, which is directly written to the display device. Frame buffering is equivalent

When using the embedded Linux driver, clock is inevitable. I checked the clock information online today and found that most of the information on the Internet is about the clock mechanism of the Linux kernel, not the clock of the Linux Device Driver.

In this article, I will introduce and summarize every step of learning embedded Linux. I would like to sum up my experience, and I hope it will be convenient for anyone who wants to get started with embedded Linux. If any error occurs, please

Linux's low power consumption research has also been around for some time. I have basically figured out the implementation method of Low Power Consumption (mainly divided into mechanisms and policies). During this period, I will focus on mechanisms.

I recently read "laruence's Linux private house dish", which is indeed a good book that gives me a deep understanding of file attributes and permissions. The summary is as follows. (Note: The pictures in this blog post are from the book "laruence's
