✨ drmm_connector_init(9) ✨

okay bestie, so this one's from the drmm_connector_init(9) page in the Kernel API Manual and it's literally the glow-up ritual for a connector that already exists. no cap, it's giving "makeover montage" energy 💅

🌸 NAME 🌸

drmm_connector_init — Init a preallocated connector

like, it initialises a connector you already allocated. the name says it all, iykyk 🎀

🦋 SYNOPSIS 🦋

int drmm_connector_init (struct drm_device *dev , struct drm_connector
*connector , const struct drm_connector_funcs *funcs , int
connector_type , struct i2c_adapter *ddc );

💖 ARGUMENTS 💖

  • dev — the DRM device, aka the main character of this whole situation 👑
  • connector — the connector you're init-ing. yes, that one. her.
  • funcs — the callbacks for this connector, aka her whole personality ✨
  • connector_type — the user visible type of the connector. what she shows the world 💅
  • ddc — optional pointer to the associated ddc adapter. optional bestie, no pressure 🫶

⭐ DESCRIPTION ⭐

so here's the tea: this initialises a preallocated connector. and listen — connectors should be subclassed as part of driver connector objects. that's just how we do it, fr fr.

Cleanup is automatically handled with a call to drm_connector_cleanup in a DRM-managed action. so you don't gotta lift a finger, she cleans up after herself ✨ iconic behaviour honestly.

The connector structure should be allocated with drmm_kzalloc. like, that's the move. don't be out here doing your own thing.

🚨 ok this part matters: the drm_connector_funcs.destroy hook must be NULL. must. not negotiable, bestie. if you're setting that hook you're doing it wrong and it's not gonna slay 😭

🔥 RETURN 🔥

Zero on success, error code on failure. that's it, that's the whole vibe check 💀

🌈 SEE ALSO 🌈

okay so she has a LOT of friends, and honestly? obsessed. here's the full squad, no one gets left out 🫶

and that's the whole page, bestie!! this little beauty lives at ./drivers/gpu/drm in the Kernel API Manual, dated October 2026, and it's filed under drmm_connector_init(9) in case you need to find her again 💖✨🎀🦋🌸
