TILE GROUP(9)

📦 version 7.3.1, in nixpkgs unstable

✨ Tile group ✨

okay bestie, welcome to Tile group(9) from the Kernel API Manual — this one's short and sweet and honestly kind of a vibe 🫶

💅 the whole thing, explained

So. Tile groups are how we represent tiled monitors with a unique integer identifier. Think of it like giving your multi-monitor setup its own group chat, and the group chat has a numeric ID. periodt.

Here's the cute part: tiled monitors that use DisplayID v1.3 come with a unique 8-byte handle. We store that handle in a tile group, so every tile in a monitor group has a common identifier to point at. iykyk 💖

The property is literally called "TILE" — no cap, that's the name.

Drivers can manage tile groups using these three:

  • drm_mode_create_tile_group — makes one 🌱
  • drm_mode_put_tile_group — puts one back 👋
  • drm_mode_get_tile_group — grabs one 🎀
But here's the tea: this is only needed for internal panels where the tile group information is exposed through a non-standard way. So don't go doing this everywhere, bestie — it's a special-case situation 💀
