Hands On Projects For The Linux Graphics Subsystem !!hot!! -

Abstract

Why this matters: KMS is the foundation. It sets the resolution, depth, and scanout buffer. Everything else (Xorg, Wayland compositors) sits on top of it. Hands On Projects For The Linux Graphics Subsystem

• Introduction to DRM
• Creating a DRM device
• Rendering graphics with DRM

Before diving into the projects, let's take a brief look at the Linux graphics subsystem. The Linux graphics subsystem consists of several layers, including: Abstract Why this matters: KMS is the foundation

9. Creating a Linux Graphics Virtual Machine

Creating a Linux graphics virtual machine can be a great way to provide a sandboxed environment for graphics testing and development. Introduction to DRM Creating a DRM device Rendering

In this project, we'll use GPU profiling tools to optimize the graphics performance of a Linux application. This project will help you understand how to use profiling tools to identify performance bottlenecks and optimize graphics rendering.

Verification

• Ability to correlate a single frame: client wl_surface.commit → compositor handling → kernel drm_mode_atomic_ioctl.
• Graph the latency from touch input to screen update.
