An operating system is the part of the system that is responsible for com

number of bytes that are filled, the memory consumption is reduced. However, for those structures that are already in the kernel, you must not arbitrarily adjust the order of their elements, because many of the existing methods in the kernel get elements by positioning them in the structure. 20th Patch, Development and Community 1.

we have already used the official image to set up the Raspberry Pi development environment, it can be said to be able to use the application, but if the official kernel has some features that do not meet our needs or need to partially crop the kernel, then we need to crop the Raspberry Pi kernel, Here we teach you how

Many Linux application developers and Linux Device Driver developers are excited and excited in the face of constantly upgrading linux kernels, GNU development tools, and various graphic libraries in Linux environments. I am excited that new software and tools provide me wit

fixes many vulnerabilities found in earlier versions, it is necessary for Linux users to regularly upgrade and update the system kernel. 　　 Generally, the kernel version serial number is represented by three numbers, for example, 2.2.14. The higher the version number, the stronger the function. The version number is divided into two series: one is the product se

To accomplish this, we need to run the following command in a terminal or shell. # yum groupinstall "Development Tools" # yum install gcc ncurses ncurses-devel Then, we will upgrade our entire system. # y

Ftrace is a debugging tool available in the Linux kernel. Using Ftrace can keep track of what is happening in the kernel, which is useful when debugging bugs or parsing the kernel. This series of articles introduces Ftrace, which is divided into three parts. This article is the first part, introduced the

example, 2.2.14. The higher the version number, the stronger the function. The version number is divided into two series: one is the product series, named after an even number, such as 1.2.x, 2.0.x, and 2.2.x. The version number is stable and has been thoroughly tested; the other is the development and testing series, which is named after an odd number for testing the latest functions. It is not recommended for beginners and production. Later in this

configuration, select the last item--save an Alternate configuration File , and then select OK to save the configuration.5. Enter the command: make to compile it (Root permission). What cross-compilation path configuration and support platform configuration, people embedded in the source code inside the makefile file has already been configured for you, this need not worry. Wait for the compilation to finish, enter the kernel source folder under Vml

Introduction to Linux kernel Interpretation For many Linux enthusiasts who are very interested in the kernel, this article aims to introduce an entry method for interpreting the Linux kernel source code, rather than explaining t

【It168] "Some people are leaders of millions of people in their lives, while others are born to write software that subverts the world. The only one who can do both is Linus Torvalds ." This is what times weekly commented on Linus, the father of Linux. Linus is not only an IT wizards, but also an optimistic and humorous scholar. The it168 reporter took you to the interview with the father of Linux. {LOC (th
