💅 drmm_writeback_connector_init 💅

okay bestie, welcome to the Kernel API Manual — that's the manual name, and this page is all about drmm_writeback_connector_init. It's giving "initialize a writeback connector with a custom encoder" energy, and honestly? iconic. 💖

✨ NAME ✨

drmm_writeback_connector_init — Initialize a writeback connector with a custom encoder. That's the whole assignment, no cap.

🛠️ SYNOPSIS 🛠️

int drmm_writeback_connector_init (struct drm_device *dev , struct
       drm_writeback_connector *wb_connector , const struct drm_connector_funcs
       *con_funcs , struct drm_encoder *enc , const u32 *formats , int
       n_formats );

🌸 ARGUMENTS 🌸

  • dev — DRM device. The main character device, periodt.
  • wb_connector — Writeback connector to initialize. This is the glow-up target.
  • con_funcs — Connector funcs vtable. The behavior blueprint, iykyk.
  • enc — Encoder to connect this writeback connector. Custom encoder, cute.
  • formats — Array of supported pixel formats for the writeback engine. The pixel format menu.
  • n_formats — Length of the formats array. Gotta know how many we're working with.

🦋 DESCRIPTION 🦋

okay so this function literally initializes a writeback connector and registers its cleanup. Two-for-one, no cap. 💅

It creates the writeback-connector-specific properties if they have not been already created (so if they're already there, it's not re-doing them), initializes the connector as type DRM_MODE_CONNECTOR_WRITEBACK, and correctly initializes the property values. Slay. ✨

🎀 RETURN 🎀

0 on success, or a negative error code. So zero is the win, negative is the "oop". 💀
