linux-driver-sandbox

A personal workspace for learning and experimenting with custom Linux kernel modules and device drivers.

Overview

This repository contains educational kernel modules and tools designed to explore Linux driver development concepts. Each module demonstrates specific kernel programming patterns and interfaces.

Projects

1. kern_vault - Procfs-based Message Vault

A simple kernel module that provides a mechanism to store and retrieve messages via the /proc filesystem.

2. kern_monitor- Linux Kernel CPU and Process Monitoring Module

A kernel module that exposes kernel-space system metrics and task states to user-space via the /proc filesystem using seq_file interfaces.

Documentations

1. kern_vault

2. kern_monitor
