Linux compiling and installation kernel, linux compiling Kernel

I. Introduction

Kernel is the core of an operating system. It manages system processes, memory, device drivers, files, and network systems, and determines system performance and stability. Linux, as a free software, is constantly updated with the support of many enthusiasts. The new kernel fixes bugs in the old kernel and adds many new features. If you want to use these new features or customize a more efficient and stable kernel based on your system, you need to recompile the kernel.
