Hands On Projects For The Linux Graphics Subsystem

Write a minimal virtual DRM driver that exposes a simple framebuffer and supports page flipping.

This is the core of the Linux graphics architecture. The Direct Rendering Manager (DRM) is the kernel subsystem that manages GPU hardware.

Creating a Linux graphics toolkit can be a great way to provide a simple and easy-to-use API for graphics programming. Hands On Projects For The Linux Graphics Subsystem

Goal: Understand DRM driver internals by writing a minimal virtual DRM driver (as a kernel module).

Concepts:

Task:

Outcome: A learning-level DRM driver that can be loaded without real hardware. Write a minimal virtual DRM driver that exposes

Checkpoints:

Learning outcomes:

Goal: Simulate a monitor unplug/replug and manually reinitialize the display pipeline using only sysfs and debugfs.

Why this matters: Hot-plug handling is where DRM, user-space compositors, and event loops meet. Outcome: A learning-level DRM driver that can be
