✨ drmm_connector_hdmi_init(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a little kernel-side gem called drmm_connector_hdmi_init, and honestly? it's giving "set up your HDMI connector the DRM-managed way" and we're obsessed 🎀

---

🌸 NAME 🌸

drmm_connector_hdmi_init — Init a preallocated HDMI connector 💅

---

🦋 SYNOPSIS 🦋

int drmm_connector_hdmi_init (struct drm_device *dev , struct
drm_connector *connector , const char *vendor , const char *product ,
const struct drm_connector_funcs *funcs , const struct
drm_connector_hdmi_funcs *hdmi_funcs , int connector_type , struct
i2c_adapter *ddc , unsigned long supported_formats , unsigned int
max_bpc );

bestie look at that signature. it's long. it's iconic. it ate and left no crumbs 🔥

---

💜 ARGUMENTS 💜

• dev — the DRM device, obvi 🖥️
• connector — a pointer to the HDMI connector you're about to init ✨
• vendor — HDMI Controller Vendor name 🏷️
• product — HDMI Controller Product name 🏷️
• funcs — callbacks for this connector 🫶
• hdmi_funcs — HDMI-related callbacks for this connector 📺
• connector_type — user visible type of the connector 👀
• ddc — optional pointer to the associated ddc adapter (optional!! key word 🎀)
• supported_formats — Bitmask of drm_output_color_format listing supported output formats 🌈
• max_bpc — Maximum bits per char the HDMI connector supports 💅

---

🌟 DESCRIPTION 🌟

So what does it actually do? It initialises a preallocated HDMI connector. Periodt. 💅

And here's the cute part — connectors can be subclassed as part of driver connector objects 🧚 so you're not locked into just the plain thing, you can build your own lil driver connector object around it.

Cleanup? Don't even worry about it, bestie — it's automatically handled with a call to drm_connector_cleanup in a DRM-managed action 😌✨ the kernel literally handles the breakup for you.

🚨 Important things, no cap: - The connector structure should be allocated with drmm_kzalloc. - The drm_connector_funcs.destroy hook must be NULL. Not "should", not "maybe" — must. Like, fr fr. 💀

---

⭐ RETURN ⭐

Zero on success, error code on failure 🫶 (so like, check it, bestie 🙈)

and that's the whole page, bestie!! go init some connectors, you got this 💖
