Welcome to my personal GitHub repository, where I document my learning journey as I explore, hack, tinker, and configure the xv6 operating system in various ways. This project serves as a record of my progress and the knowledge I've gained while delving into the intricate world of operating systems.

xv6 is a simple, educational operating system developed at MIT as a reimplementation of the Unix Version 6 (v6) operating system. It serves as a minimal and understandable platform for learning the fundamentals of operating systems and system programming. xv6 is written in C and x86 assembly, making it an excellent environment for hands-on learning.

To begin your journey with xv6, follow these steps:

1. Clone the Repository: Start by cloning this repository to your local machine.

   git clone https://github.com/your-username/xv6-hacking.git

2. Run xv6: Build and launch the xv6 operating system in the QEMU emulator.

   make qemu-nox

3. Explore & Tinker: Begin exploring the source code and experiment with the OS. The code is well-commented and organized, making it a great resource for learning.

My journey with xv6 OS is a personal exploration of the following aspects:

My first step was to set up the xv6 environment. I cloned the xv6 repository, built the image, and ran it in the QEMU emulator. This was my introduction to the xv6 operating system and its basic structure.

I started exploring the source code to understand how a real operating system is structured. The codebase is well-commented, making it a valuable resource for learning. I delved into various components such as processes, file systems, and memory management.

As I became more comfortable with the codebase, I began experimenting and hacking. I created custom system calls, modified existing ones, and developed new features within the operating system. This allowed me to gain practical insights into system programming.

I tried different configurations to tailor xv6 to my needs. I explored ways to optimize system performance, modify scheduling policies, and add or remove system components. This process helped me grasp how to adapt an OS to specific requirements.

Throughout my journey, I maintained documentation to capture my learnings, challenges, and achievements. I believe in the importance of sharing knowledge, so I created this repository to document and share my experience with others who are on a similar path.

Each laboratory exercise corresponds to a general topic that encapsulates the features of xv6.
