UNION HDMI_INFOFRAME(9)

💖 NAME 💖

union hdmi_infoframe — okay so this is literally the overall union of all the abstract infoframe representations. all of them. one union to hold them all, bestie 👑

✨ SYNOPSIS ✨

union hdmi_infoframe {
    struct hdmi_any_infoframe any;
    struct hdmi_avi_infoframe avi;
    struct hdmi_spd_infoframe spd;
    union hdmi_vendor_any_infoframe vendor;
    struct hdmi_audio_infoframe audio;
    struct hdmi_drm_infoframe drm;
 };

no cap, that's the whole shape of it 🫶

🎀 Members 🎀

• any — the generic infoframe, aka the "idk what you are yet" one 💅
• avi — the avi infoframe, living its best life 🌈
• spd — the spd infoframe, iconic as always ⭐
• vendor — a union of all the vendor infoframes, like a little group chat of manufacturers 🧚
• audio — the audio infoframe, and yes she's loud 🔥
• drm — the Dynamic Range and Mastering infoframe, highkey the main character of the whole struct 👑

🦋 Description 🦋

So here's the tea ☕ — this union is what the generic pack function uses. and the way that this works is lowkey genius: every single infoframe shares the same header, and that header also tells you which type of infoframe should be packed. so the pack function can just vibe-check the header and know exactly what it's dealing with. slay 💅✨
