drm_connect...ile_property(9)

📦 version 7.3.1, in nixpkgs unstable

💅 drm_connector_set_tile_property — from the Kernel API Manual, bestie ✨

Okay so before we even get into it — this page lives in the Kernel API Manual, section 9, and the function is literally called drm_connector_set_tile_property. Say that five times fast. 🫶

🌸 NAME 🌸

drm_connector_set_tile_property — sets the tile property on a connector. That's the whole vibe. Short, sweet, slays.

✨ SYNOPSIS ✨

int drm_connector_set_tile_property (struct drm_connector *connector );

🎀 ARGUMENTS 🎀

  • connector — the connector you're setting the property on. That's it, that's the one. Point it at your fave and go 💅

🦋 DESCRIPTION 🦋

So here's the tea: this function looks up the tile information for a connector, and if that info actually exists, it creates a property so userspace can parse it. Not me making properties out of thin air — only when the tile info is really there, okay? 🙈

And what does the property even look like? It's giving 8 integers, separated by ':'. Eight. Integers. Colon-separated. Iconic formatting, no notes. ⭐

Where's this actually used? Dual port tiled displays with DisplayPort SST or DisplayPort MST connectors. That's the use case, periodt.

💖 RETURN 💖

  • Zero on success 🎉
  • errno on failure 😭

🔥 SEE ALSO 🔥

This list is long long, bestie, but we do not skip. Every single one, in order, for the culture 👑

Yes, standard connector properties(9) really is in there twice. Not a typo on my end, I promise — I keep it exactly as the original does. 💀

Sign-off time, bestie 🧚 This lil page comes from ./drivers/gpu/drm, and it's dated October 2026, still hanging out up in section 9 of the Kernel API Manual. Go forth and tile those displays 💜🌸🍓
