💅 drm_connector_dynamic_init(9) — Init a preallocated dynamic connector

okay so bestie, this is the drm_connector_dynamic_init(9) page from the Kernel API Manual, and it’s literally all about getting a preallocated dynamic connector ready without chaos ✨

🌸 NAME 🌸

drm_connector_dynamic_init — init a preallocated dynamic connector 🫶

✨ SYNOPSIS ✨

int drm_connector_dynamic_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, bestie 💖
  • connector — the connector you’re initialising, no cap
  • funcs — the callbacks for this connector 👑
  • connector_type — the user visible type of the connector
  • ddc — pointer to the associated ddc adapter 🦋

🦋 DESCRIPTION 🦋

okay so this function initialises a preallocated dynamic connector 💅 Connectors should be subclassed as part of driver connector objects. The connector structure should not be allocated with devm_kzalloc. periodt.

Drivers should call this for dynamic connectors which can be hotplugged after drm_dev_register has been called already, e.g. DP MST connectors. For all other — static — connectors, drivers should call one of the drm_connector_init*()/drmm_connector_init*() functions. iykyk 🌈

After calling this function the drivers must call drm_connector_dynamic_register. no skipping, bestie 😭

To remove the connector the driver must call drm_connector_unregister followed by drm_connector_put. Putting the last reference will call the driver’s drm_connector_funcs.destroy hook, which in turn must call drm_connector_cleanup and free the connector structure. that’s the whole lifecycle vibe 🔥

🌟 RETURN 🌟

Zero on success, error code on failure. slay 💖
