Linux kernel source code storage path analysis

The Linux kernel is an open source operating system kernel, and its source code is stored in a dedicated code repository. In this article, we will analyze the storage path of the Linux kernel source code in detail, and use specific code examples to help readers better understand.

1. Linux kernel source code storage path

Linux kernel source code is stored in a Git repository named linux, which is hosted at [https:// github.com/torvalds/linux](https://github.com/torvalds/linux). In this article, we will use this warehouse as an example to analyze the storage path of the Linux kernel source code.

2. Kernel source code directory structure

The directory structure of the Linux kernel source code is very large and complex, and is mainly divided into the following important directories:

• arch: Contains architecture-related code, such as code for x86, ARM and other different architectures.
• block: Contains the code for the common layer of block devices.
• drivers: Contains the driver code for hardware devices.
• fs: Contains file system-related code.
• include: Contains the kernel header files.
• kernel: Contains the kernel core code.
• mm: Contains code related to memory management.
• net: Contains the relevant code of the network protocol stack.
• scripts: Contains the scripts needed to build and maintain the operating system.

3. Specific code example

The following is a simple example code that shows how to clone the Linux kernel source code to the local through Git:

git clone https://github.com/torvalds/linux.git

Next, we will enter the directory where the source code is located and view some of the code files:

cd linux
ls arch/x86

In the above code example, we use the git clone command to clone the Linux kernel source code Go to the local computer and view some files in the arch/x86 directory through the ls command.

4. Source code learning and contribution

Linux kernel source code learning and contribution is a complex and meaningful task. By deeply understanding the kernel source code, we can better understand how the operating system works and contribute to the open source community. Readers can participate in the development of the Linux kernel by reading code, debugging code, and submitting patches.

Conclusion

This article introduces the storage path and directory structure of the Linux kernel source code, and shows how to obtain and view the source code through specific code examples. It is hoped that readers can have a deeper understanding of the source code structure of the Linux kernel through the analysis and examples of this article, so as to better learn and participate in the development of the Linux kernel.
