💅 drm_connector_init(9) — the Kernel API Manual page that's here to init your preallocated connector ✨

Okay so bestie, welcome to the drm_connector_init(9) glow-up from the Kernel API Manual. This is the page where we set up a preallocated connector and make it feel like the main character. No cap, it's giving "one function, big responsibility." 🎀

✨ NAME ✨

drm_connector_init — init a preallocated connector. That's the whole assignment, and it ate. 💅

🦋 SYNOPSIS 🦋

int drm_connector_init (struct drm_device *dev , struct drm_connector
*connector , const struct drm_connector_funcs *funcs , int
connector_type );

🎀 ARGUMENTS 🎀

  • dev — the DRM device. The whole setup's home base, iykyk. 🏠
  • connector — the connector to init. This is the one getting the makeover. ✨
  • funcs — callbacks for this connector. The little behavior squad that comes with it. 🫶
  • connector_type — user visible type of the connector. Yes, "user visible" is in the original, so we're keeping it exactly like that. 👀

🌸 DESCRIPTION 🌸

Initialises a preallocated connector. Connectors should be subclassed as part of driver connector objects. That's the vibe: the connector isn't out here doing solo main-character nonsense — it gets subclassed as part of driver connector objects. 💖

At driver unload time the driver's drm_connector_funcs.destroy hook should call drm_connector_cleanup and free the connector structure. Like, that's the cleanup check, bestie. Don't leave your connector looking a mess. 🧹

🚨 Important: the connector structure should not be allocated with devm_kzalloc. The original says it, we're saying it louder: not it. 🙅‍♀️

💅 NOTE 💅

Consider using drmm_connector_init instead of drm_connector_init to let the DRM managed resource infrastructure take care of cleanup and deallocation. So like… if you want the managed-resource infrastructure to handle the cleanup and deallocation for you, that's the option. Slay. ✨

⭐ RETURN ⭐

Zero on success, error code on failure. Short king return values, but iconic. 💀

🌈 SEE ALSO 🌈

Okay so this list is long, but we do not skip. Every single reference from the original is here, in order, because accuracy is the moment. 👑

Also yes, standard connector properties(9) really does show up twice up there — the original listed it twice, so we're keeping it twice. Periodt. 💁‍♀️

Mwah 💋 and that's the page! This little love letter came from the source/version ./drivers/gpu/drm, dated October 2026, and it's still out here being drm_connector_init(9). Go init something preallocated, bestie. 🦋✨
