Collection of Linux Kernel Modules and PoC to discover, learn and practice Linux Kernel Development

Implement a linux driver. This driver must take the form of a loadable kernel module. Inside the loadable kernel module, I must implement a virtual character device. This virtual character device must enable the user to play a game of Reversi(Othello) against the CPU.

Development of Device Driver ( Character device / null driver)

CharPulse is a Linux character device driver with a dynamically resizing kernel buffer. It supports read, write, append, and clear operations, allowing storage of large amounts of data safely.

To develop and use kernel modules and character devices. And learn how the Linux OS maintains list of processes and their execution states.

A Linux kernel module that implements a thread-safe circular buffer logger as a character device (/dev/klogger). Provides a simple interface for userspace applications to write and read log messages with automatic buffer management. Ideal for kernel-level debugging, monitoring, and logging purposes.

A kernel module that creates a device that always returns EIO on a read, for testing purposes.

The Linux Kernel Module (Character Device Driver) I developed on Raspberry Pi. It includes secure data transfer (Read/Write) between User Space and Kernel Space, the file_operations structure, and the driver registration (major/minor number) mechanisms.

Kernel level miscellaneous character device to exchange information between user-level processes. The device maintains a thread-safe FIFO queue containing a configurable number of data blocks.
