ENUM SSAM_SSH_TID(9)

🎀 NAME 🎀

enum ssam_ssh_tid — target/source IDs for Serial Hub messages, bestie ✨

(also hi, this is from the Kernel API Manual, section 9, we're in the kernel docs now 💅)

🦋 SYNOPSIS 🦋

enum ssam_ssh_tid {
    SSAM_SSH_TID_HOST ,
    SSAM_SSH_TID_SAM ,
    SSAM_SSH_TID_KIP ,
    SSAM_SSH_TID_DEBUG ,
    SSAM_SSH_TID_SURFLINK

};

🌈 Constants 🌈

okay so the enum has exactly five members and each one is literally a "who is talking" label, iykyk 👑

• SSAM_SSH_TID_HOST — that's us! we're the kernel Serial Hub driver in this situation 🫶
• SSAM_SSH_TID_SAM — the Surface Aggregator EC, iconic behavior honestly 👑
• SSAM_SSH_TID_KIP — keyboard and peripheral controller 🎹
• SSAM_SSH_TID_DEBUG — the debug connector 🐛
• SSAM_SSH_TID_SURFLINK — the SurfLink connector 🦋
