STRUCT HBM_CLIENT_CONNECT_REQUEST(9)

💅 struct hbm_client_connect_request(9) — Kernel API Manual, bestie edition 🎀

okay so this is the manual page for struct hbm_client_connect_request, living in the Kernel API Manual section 9, and it's basically the little envelope that says "hey, connect" or "okay, disconnect" ✨

🌸 NAME 🌸

struct hbm_client_connect_request — connect/disconnect request 🫶

---

✨ SYNOPSIS ✨

here's the whole struct, exactly as it is, no notes:

struct hbm_client_connect_request {
    u8 hbm_cmd;
    u8 me_addr;
    u8 host_addr;
    u8 reserved;
 };

like, four u8s and a dream, honestly 💖

🦋 Members 🦋

• hbm_cmd — bus message command header 💌 (this is the part that says what kind of message we're even doing)
• me_addr — address of the client in ME 📍
• host_addr — address of the client in the driver 📍
• reserved — reserved 🙈 (it's giving "don't touch, it's reserved", and we don't touch)
