bufferDriver

Linux kernel character device driver demonstrating basic driver operations.

Overview

A simple Linux kernel module that implements a character device driver with buffer operations. Demonstrates kernel-space programming, ioctl interface, and user-space interaction.

Features

• Character device driver (/dev/buffer_driver)
• Read/write operations
• ioctl commands for control
• Memory buffer management
• Test application included

Build & Test

# Build kernel module and test app
./build_and_test.sh

# Load module
sudo insmod buffer_driver.ko

# Run test
./test_buffer

Structure

├── Makefile              # Kernel module build
├── buffer_driver.c      # Driver implementation
├── test_buffer.c        # User-space test app
└── build_and_test.sh    # Build script

Requirements

• Linux kernel headers
• GCC, Make
• Root access for module loading
