Learn how an operating system kernel boots, manages memory, and schedules processes by reading annotated source code.
Understand interrupt handling, process creation, and context switching through narrative explanations of real kernel code.
Study how a shell loads and executes programs from disk by tracing the actual system calls and kernel routines.
Build foundational knowledge of OS internals without relying on dense textbooks or academic papers.
Requires a Linux environment or VM to compile and run 0.11 kernel; cross-compilation toolchain setup may be needed.
This repository is a Chinese-language reading guide for the source code of Linux 0.11, an early version of the Linux kernel. Its stated goal, in the README's own words, is to take readers through the core code of Linux 0.11 and the design ideas behind an operating system. The author frames it as reading kernel source the way you would read a novel, the project description literally translates to something like "you call this thing an operating system source?, let's read the Linux 0.11 core code like a novel." The way it works is that the repository serves as a structured index of articles. Each article walks through a small slice of the kernel, in execution order, starting from the very first two lines of boot code and proceeding step by step through what those lines do and why. The README's table of contents organises the articles into five parts. Part one covers the bring-up work before entering the kernel, including initial memory setup, jumping into protected mode, and the segment-register and IDT/GDT preparations needed to reach the main function. Part two covers the early initialisation routines: memory, interrupts (trap_init), block devices, the console (tty_init), the clock (time_init), the scheduler (sched_init), buffers, and the hard disk. Part three follows the birth of a new process, including the switch from kernel mode to user mode, scheduler design, the fork system call, and copy-on-write. Part four walks through how the shell program is loaded and reaches the prompt, ending with a side article on kernel debugging. Part five then traces the lifecycle of a single command through the whole system. You would use this if you are studying operating systems and want a guided, narrative tour of a real (small, classic) Unix-like kernel rather than a dry textbook. The README also links to a companion book published by the author. The repository itself is mainly HTML and Markdown content; the kernel code being discussed is written in C and assembly, but the project ships explanations rather than runnable code. The full README is longer than what was provided.
