# Linux Kernel Modules (LKM) Project
Welcome to the **Linux Kernel Modules (LKM)** project repository! This project is based on assignments from the **Operating System Concepts, 10th Edition** textbook, specifically focusing on Linux kernel modules, task listing, kernel data structures, and system building.
## Project Overview
In this project, you will develop kernel modules for a Linux system to perform a variety of tasks. The assignments are organized into three main parts:
### Part I - Introduction to Linux Kernel Modules (LKM) - Chapter 2
- **Assignment: Introduction to LKM**
This part will help you get started with Linux Kernel Modules (LKM), covering the basics of module development and compilation.
- **Learning Resources**:
- Chapter 2 of *Operating System Concepts, 10th Edition*
- Section 2.9 on building and booting a Linux system
- **Key Topics**:
- Understanding the structure and building blocks of LKM
- Compiling and loading modules into the Linux kernel
---
### Part II - Linux Kernel Module for Listing Tasks - Chapter 3
- **Assignment: ps-el**
Develop a kernel module to list processes running on the system, similar to the `ps -el` command.
- **Assignment: ps-eLf**
Extend the `ps-el` module to display more detailed information, resembling `ps -eLf`.
- **Learning Resources**:
- Chapter 3 of *Operating System Concepts, 10th Edition*
- Pages 201–205 for detailed instructions
- **Key Topics**:
- Listing tasks in the kernel using kernel data structures
- Implementing process listing functionality in kernel space
---
### Part III - Kernel Data Structures - Chapter 3
- **Assignment: dmesg**
Implement a kernel module to interact with the `dmesg` command and display kernel messages.
- **Assignment: collatz**
Create a kernel module to compute the Collatz sequence and output the results.
- **Learning Resources**:
- Chapter 3 of *Operating System Concepts, 10th Edition*
- Pages 205–208 for detailed instructions
- **Key Topics**:
- Understanding and utilizing kernel data structures
- Implementing the `dmesg` functionality and algorithmic tasks in kernel space
---
## Setup and Installation
### Requirements
- A Linux virtual machine (VM) is recommended to avoid crashes or errors on the host system.
- Use VMware Player, VirtualBox, Microsoft Hyper-V, or any similar tool.
- A basic understanding of Linux kernel module programming and C language.
### Steps to Build the Kernel Modules
1. Clone the repository:
```bash
git clone
cd
2. Build the kernel module:
```bash
make
```
3. Load the kernel module:
```bash
sudo insmod .ko
```
4. Check the output of the module (depending on the assignment):
* Use dmesg to view kernel log messages.
* For process listing assignments, use the appropriate ps commands.
5. Unload the kernel module:
```bash
sudo rmmod
```
## Additional Notes
* Caution: Working with the Linux kernel can cause system instability if errors occur. It is strongly recommended to complete these exercises on a virtual machine.
* Refer to the relevant chapters in the textbook for step-by-step instructions
