ENUM TB_LINK_WIDTH(9)

💖 NAME 💖

okay so bestie, this is enum tb_link_width(9) from the Kernel API Manual, and it is literally the enum for Thunderbolt/USB4 link width. That's the whole vibe: one little enum, very specific lane business ✨.

✨ SYNOPSIS ✨

the lineup is right here, no cap:

enum tb_link_width {
    TB_LINK_WIDTH_SINGLE ,
    TB_LINK_WIDTH_DUAL ,
    TB_LINK_WIDTH_ASYM_TX ,
    TB_LINK_WIDTH_ASYM_RX

};

🌸 Constants 🌸

• TB_LINK_WIDTH_SINGLE — Single lane link. one lane, that's it, iconic minimalism 🎀
• TB_LINK_WIDTH_DUAL — Dual lane symmetric link. two lanes and symmetric, slay ⚖️
• TB_LINK_WIDTH_ASYM_TX — Dual lane asymmetric Gen 4 link with 3 transmitters. Gen 4, dual lane, asymmetric, 3 transmitters — okay go off 🔥
• TB_LINK_WIDTH_ASYM_RX — Dual lane asymmetric Gen 4 link with 3 receivers. same Gen 4 asymmetric dual-lane energy but with 3 receivers, periodt 💅

catch u later, bestie — this cutie came from ./include/linux, dated October 2026, and it's literally enum tb_link_width(9) 🫶💖
