drm_connecto...tach_encoder(9)

📦 version 7.3.1, in nixpkgs unstable

💅 drm_connector_attach_encoder(9) — yes this is from the Kernel API Manual bestie

okay so picture this: you're deep in the DRM (Direct Rendering Manager) corner of the kernel, right, and you need a connector to actually know about an encoder. That's it. That's the whole vibe. This is the function that makes the link-up happen ✨

🌸 NAME 🌸

drm_connector_attach_encoder — literally just attach a connector to an encoder, no cap 💅

✨ SYNOPSIS ✨

int drm_connector_attach_encoder (struct drm_connector *connector ,
struct drm_encoder *encoder );

🎀 ARGUMENTS 🎀

  • connector — the connector you're attaching, bestie. She's the main character here 🫶
  • encoder — the encoder you're attaching that connector to. The plus-one, the supporting role 💖

🦋 DESCRIPTION 🦋

So what this does is it links up a connector to an encoder. Simple as. Iconic, even 👑

But listen — the routing restrictions between encoders and crtcs? Those don't stay secret. They're exposed to userspace through the possible_clones and possible_crtcs bitmasks. Not me explaining the whole lore but yes exactly 😭

⭐ RETURN ⭐

  • Zero on success — slay, we ate 🎉
  • Negative errno on failure — it's giving lowkey tragic, but at least you know 💀

okay this is the part where the whole group chat gets @'d, there's a lot of them and they all matter:

and that's the whole page, bestie 💜 this lil beauty lives over in ./drivers/gpu/drm and the version stamp says October 2026 — so yeah, she's from the future, we love a time-travelling icon 🌈⏳
