drm_atomic_h...e_infoframes(9)

💅 NAME 💅

Okay bestie, gather round, because this is the drm_atomic_helper_connector_hdmi_update_infoframes</p> page — the one and only, and it's literally about Update the Infoframes. That's it, that's the whole vibe. ✨

This page lives in the Kernel API Manual, so yeah, it's giving very much kernel-docs main character energy. 🎀

🌸 SYNOPSIS 🌸

int drm_atomic_helper_connector_hdmi_update_infoframes (struct drm_connector *connector , struct drm_atomic_commit *state );

That's the whole signature, no cap. 🫶

---

✨ ARGUMENTS ✨

• connector — a pointer to the HDMI connector, like, the actual connector bestie, the thing we're updating 💖
• state — the HDMI connector state we're gonna generate the infoframe from 🌈

🦋 DESCRIPTION 🦋

So here's the tea, okay? This function is meant for HDMI connector drivers to write their infoframes. That's the job. That's what it does. Slay. 💅

It will typically be used in a drm_connector_helper_funcs.atomic_enable implementation — so that's the moment where you'd normally slide it in. iconic placement honestly 🎀

⭐ RETURN ⭐

• Zero on success 🎉
• error code on failure 😭

That's it, that's the whole return situation — zero means we ate, anything else means we did not eat.

Okay that's the whole page bestie, we're done here 💜 — this one came out of ./drivers/gpu/drm/display, dated October 2026, and honestly the truncated title drm_atomic_h...e_infoframes(9) is doing the most with the ellipsis and we respect it 🍓✨
