A five-star bake. Worth schmearing, sharing, saving.
Summary
This article introduces libdrm-ocaml, an OCaml binding for Linux's Kernel Mode Setting (KMS) API, which allows applications to query and configure display hardware. The author explains how to use this library to discover available hardware, configure monitors to display bitmaps, and render 3D animations, providing a practical introduction to KMS programming through interactive REPL sessions.
Key quotes
· 3 pulledLinux provides the KMS (Kernel Mode Setting) API to let applications query and configure display settings.
I found the C API a little verbose and hard to follow so I made libdrm-ocaml, which lets us run commands interactively in a REPL.
We'll start by discovering what hardware is available and how it's currently configured, then configure a monitor to display a simple bitmap, and then finally render a 3D animation.
