xv6 Operating System Internals and Kernel Fundamentals

Understanding how an operating system operates beneath user space is essential for writing efficient, reliable software. This text-based course demystifies kernel architecture by exploring xv6, a clean implementation of classic Unix-like operating system principles. You will gain a firm grasp of low-level system mechanics, moving from foundational terminology to process execution, page tables, and hardware abstractions. What you will learn: Understand fundamental operating system concepts including kernel space, user space, and trap handling; Explore virtual memory management, page tables, and address translation mechanics; Trace process lifecycles, context switching, and CPU scheduling logic; Implement system calls and handle hardware interrupts safely; Practice synchronization principles using spinlocks and mutual exclusion to prevent race conditions; Analyze file system organization, including inodes, logging, and block allocations. Starting with core definitions and architectural concepts, the course walks you through process management, memory allocation, and file storage structures using clear C code snippets and written explanations. Designed for developers and students eager to understand system programming, this beginner-friendly guide requires only basic familiarity with C programming.
