💅 drm_mode_get_tile_group(9) — a Kernel API Manual moment

okay bestie, so we're in the Kernel API Manual and this page is literally all about drm_mode_get_tile_group — yes that's the whole name, iconic, no notes 💖

✨ NAME ✨

drm_mode_get_tile_group — get a reference to an existing tile group 🎀

🦋 SYNOPSIS 🦋

struct drm_tile_group * drm_mode_get_tile_group (struct drm_device *dev
, const char topology_id[9] );

like, that's the whole summoning ritual, no cap ✨

🌸 ARGUMENTS 🌸

  • dev — the DRM device 🖥️ literally the thing we're poking at
  • topology_id — a 9-byte unique ID per monitor. nine bytes! specific queen behavior 💅

👑 DESCRIPTION 👑

so the vibe here is extremely simple: you take those unique bytes and use them to get a reference to an existing tile group 🫶 That's it. That's the whole function. Lowkey elegant, highkey useful, periodt.

⭐ RETURN ⭐

you get back a tile group, or NULL if it's not found 😭 (yes, the sad-path is real, always check your returns bestie)

🌈 SEE ALSO 🌈

okay this list is long long — like a full group chat of related functions, and I'm not skipping a single one because every name matters 🧚✨

💀 yes, standard connector properties(9) shows up twice. I did not make the rules, I just respect them. iykyk.

and that's the page!! 🎀 source/version? it lives under ./drivers/gpu/drm bestie, dated October 2026 — bookmark it, screenshot it, send it to the group chat 🫶✨💜
