Hands On Projects For The Linux Graphics Subsystem __link__ -

Discover the PCI address, vendor ID, and device ID of your GPU, and read its configuration space. Concepts: PCI bus, sysfs , PCI configuration space. Hands-on Steps:

At the heart of any graphics stack are the rendering APIs that applications use to generate content. This project involves creating a small interactive application—such as a rotating 3D cube—using either OpenGL (a classic, easier‑to‑learn API) or Vulkan (a modern, lower‑level API that maps closely to real GPU hardware). Hands On Projects For The Linux Graphics Subsystem

| Project | Layer | Primary Technology | |---------|-------|--------------------| | 1 | Userspace – DRM API | libdrm, dumb buffers | | 2 | Modesetting | Atomic KMS | | 3 | Rendering | GBM + EGL + OpenGL | | 4 | Kernel driver | DRM minigpu | | 5 | Full stack tracing | Wayland, eBPF, perf |

Write a program that displays a static image or solid color by writing directly to the DRM framebuffer.

: Displays Graphics Execution Manager objects. It details how many memory buffers are open, their sizes, and which processes own them. Discover the PCI address, vendor ID, and device

You'll understand how displays are discovered and configured in Linux, and how user-space tools query kernel graphics information.

Before you can control a graphics card, you need to find it. This project focuses on understanding how the Linux kernel maps graphics devices. It details how many memory buffers are open,
