drm_hdmi_avi..._quant_range(9)

💅 NAME 💅

Okay bestie, so this is the drm_hdmi_avi..._quant_range(9) page from the Kernel API Manual, and the function it's hyping up is drm_hdmi_avi_infoframe_quant_range — which does exactly one job and does it iconically: it fills the HDMI AVI infoframe quantization range information. That's it. That's the whole gig. ✨

✨ SYNOPSIS ✨

void drm_hdmi_avi_infoframe_quant_range (struct hdmi_avi_infoframe
*frame , const struct drm_connector *connector , const struct
drm_display_mode *mode , enum hdmi_quantization_range rgb_quant_range );

🎀 ARGUMENTS 🎀

• frame — the HDMI AVI infoframe 🫶 like, the thing you're filling in, bestie
• connector — the connector
• mode — the DRM display mode
• rgb_quant_range — the RGB quantization range (Q) 👑

🔥 SEE ALSO 🔥

Right, so this bad boy lives in the kernel file ./drivers/gpu/drm/drm_edid.c, and it's surrounded by a whole friend group of related calls. Not me listing all of them — but I would never leave one out, so here's literally every single one, no cap:

That's the whole page, bestie — go forth and quantize that range 💖

Little sign-off moment 🎀: this one ships out of ./drivers/gpu/drm, dated October 2026, and she's registered under drm_hdmi_avi..._quant_range(9). Slay. ✨🦋
