As the core part of the operating system, the Linux kernel is responsible for important functions such as managing hardware resources and providing system calls. This article will delve into the five major parts of the Linux kernel, including process management, file system, network communication, device driver and memory management, and provide a detailed introduction and code examples. 1. Process Management Process Creation In the Linux kernel, process creation is implemented through the fork() system call. Here is a simple example code: #include

This is a 1500-word article that explores the Linux kernel source code distribution in depth. Due to limited space, we will focus on the organizational structure of the Linux kernel source code and provide some specific code examples to help readers better understand. The Linux kernel is an open source operating system kernel whose source code is hosted on GitHub. The entire Linux kernel source code distribution is very large, containing hundreds of thousands of lines of code, involving multiple different subsystems and modules. To gain a deeper understanding of the Linux kernel source code

The previous article analyzed the page table creation for RISC-V Linux startup. It was mentioned that the RISC-V Linux entry address must be 2M aligned. Today I will talk about how to solve the 2M alignment problem, or how to optimize part of the memory.

It’s long and has a lot of technical content, so click to follow it and you won’t get lost. Preface: Understanding the Linux Kernel A computer system is a symbiosis of hardware and software. They are interdependent and inseparable. Computer hardware Linux kernel transplantation steps include peripheral devices, processors, memory, hard drives and other electronic devices that make up the computer cylinder. And without software to operate and control it, it cannot work by itself. The software that completes this control work is called the operating system. In Linux terminology, it is called the "kernel" or "core". The main modules (or components) of the Linux kernel are divided into the following parts: storage management, CPU and process management, file system, device management and driver, network communication Linux forum, and system

Hello dear readers! Here, I am honored to share with you the valuable experience and skills I have accumulated as a senior network engineer with my professional skills in the development and optimization of the Linux kernel TCP protocol stack. I believe that through this article, we can learn from each other and discuss it, and bring practical and useful reference materials to you who have a strong interest in this field or are currently working on it. 1. TCP connection establishment TCP connection establishment is a key transaction of the TCP protocol stack, but it is not uncommon to face many connection problems. After careful consideration and detailed debugging, I discovered some common and practical problems and their solutions, including preventing SYN flooding attacks (by adjusting system parameters) and dealing with network congestion (that is, using TCPFastOp

Discusses the view that the Linux kernel plays an important role in computer operating systems. Linux kernel design and implementation. Through in-depth analysis of Linux kernel design and practical applications, it reveals its prominent position and influence in this field. 1. Optimized memory management By using virtual memory management technology, the Linux kernel can efficiently complete memory allocation and recycling. With the help of the replacement page algorithm, the Linux kernel is designed and implemented to accurately handle the mapping relationship between physical memory and virtual memory. Flexible adjustments can be made based on the specific needs of the application, thereby improving overall system performance. 2. The powerful process management kernel uses its excellent multi-tasking technology to enable multiple processes to coexist harmoniously in a single system. Carefully formulated

The Android system and the Linux kernel are two closely related entities, and the relationship between them is close and complex. In the Android system, the Linux kernel plays an important role, providing underlying hardware drivers and system call support for the Android system. This article will explore the relationship between the Android system and the Linux kernel, how they interact and work together, and provide some specific code examples. Android is a mobile operating system developed based on the Linux kernel and is mainly used for mobile devices such as smartphones and tablets. L

The Linux kernel is the core of the operating system and controls access to system resources such as the CPU, I/O devices, physical memory, and file systems. During the boot process and while the system is running, the kernel writes various messages to the kernel ring buffer. These messages include a variety of information about system operations.
