drm_hdmi_ve...display_mode(9)

💖 NAME 💖

okay so this is the drm_hdmi_vendor_infoframe_from_display_mode(9) page from the Kernel API Manual, and it does exactly what the name says: it fills an HDMI vendor infoframe with data from a DRM display mode. iconic behavior, honestly 💅

---

✨ SYNOPSIS ✨

bestie, here's the exact signature — do not freestyle the punctuation, she is particular:

int drm_hdmi_vendor_infoframe_from_display_mode (struct hdmi_vendor_infoframe *frame , const struct drm_connector *connector , const struct drm_display_mode *mode );

---

🌸 ARGUMENTS 🌸

• frame — HDMI vendor infoframe. this is the infoframe getting filled, main character energy.
• connector — the connector. yes, that connector.
• mode — DRM display mode. the display mode in question, no cap.

---

🦋 DESCRIPTION 🦋

vibe check first: you only actually need to send HDMI vendor infoframes when you're using a 4k or stereoscopic 3D mode. so if you give this function literally any other mode as input, it will return -EINVAL, and that error can be safely ignored. not me warning you so you don't panic 😭

---

👑 RETURN 👑

0 on success, or a negative error code on failure. that's the whole mood, periodt.
