drm_connecto...mic_register(9)

📦 version 7.3.1, in nixpkgs unstable

💅 drm_connector_dynamic_register 💅

okay bestie, gather round — this is drm_connector_dynamic_register straight out of the Kernel API Manual, and we're gonna make it make sense. it's a (9) page, meaning it's kernel-API vibes, and yes it's about DRM connectors, no cap. 🎀

✨ SYNOPSIS ✨

int drm_connector_dynamic_register (struct drm_connector *connector );

like, that's the whole signature. short king. 👑

🌸 ARGUMENTS 🌸

  • connector — the connector you're registering. the actual one. the main character of this function call. 🫶

🦋 DESCRIPTION 🦋

so what does it even do?? it registers the userspace interfaces for a connector. basically it flips the "hey userspace, this connector exists, come get a look at it" switch for the connector you hand it. ✨

⚠️ lowkey important: only call this for connectors that were initialized by calling drm_connector_dynamic_init. that's the whole point. this function is for the dynamic girlies only.

all other connectors (the regular, non-dynamic ones) get registered automatically when you call drm_dev_register. so don't come in here trying to double-register them, that's not the vibe. 💀

and bestie, bestie, listen — when the connector is no longer available, the driver must call drm_connector_unregister. must. not "should", not "when you get around to it". it's giving cleanup era, and it's mandatory. 🧹

🔥 RETURN 🔥

  • Zero on success — slay, you did it 💖
  • error code on failure — not slay, go read the code 😭
