drm_dp_cec_...er_connector(9)

💅 drm_dp_cec_...er_connector(9) — the Kernel API Manual, but make it cute

okay so bestie, this one's from the Kernel API Manual (yes the whole manual, not just a section, she's got range) and it's literally about registering a connector. tiny function, big main character energy. let's get into it 🎀

---

✨ NAME ✨

drm_dp_cec_register_connector — she registers a new connector. that's it, that's the whole vibe. 🫶

---

🌸 SYNOPSIS 🌸

void drm_dp_cec_register_connector (struct drm_dp_aux *aux , struct
       drm_connector *connector );

no return value, she gives nothing back and honestly? iconic. returns void, slays, leaves. 💅

---

🦋 ARGUMENTS 🦋

• aux — the DisplayPort AUX channel. your little side-channel bestie that this whole thing rides on ✨
• connector — the drm connector. the connector in question. the one (1) girl. 👑

---

💖 DESCRIPTION 💖

okay so picture this: a new connector just got registered, right? and she comes with her associated CEC adapter name and her CEC adapter parent device. the whole package. 💐

so after registering the name and parent, drm_dp_cec_set_edid gets called — and that function is basically the vibe check 😭 she's there to check if the connector actually supports CEC and, if that's a yes, to register a CEC adapter. no cap, that's the entire flow. lowkey elegant, highkey important. 🔥

fr fr, the order matters here — name and parent first, then the drm_dp_cec_set_edid check. don't skip steps, bestie 🙈

• dp cec helpers(9)
• drm_dp_cec_irq(9)
• drm_dp_cec_unregister_connector(9) — the breakup arc 💔

⭐ the cute little sign-off ⭐

this page lives in ./drivers/gpu/drm/display, it's dated October 2026 (yes she's from the future, we stan a forward-thinking queen 🧚), and the page herself is drm_dp_cec_...er_connector(9) — truncated name and all, and she still ate. periodt. 💜✨

go register those connectors, bestie, i believe in you 🍓
