ENUM ISHTP_HBM_STATE(9)

💅 enum ishtp_hbm_state(9) 💅

okay so bestie, this is a page straight out of the Kernel API Manual — like, the actual kernel docs, for real. We're talking about enum ishtp_hbm_state, which is literally the host bus message protocol state. Yeah. That one. Sit down, grab a strawberry 🍓, and let's get into it.

✨ NAME ✨

enum ishtp_hbm_state — the host bus message protocol state. that's the whole vibe. it's a state enum. it tracks where you are in the HBM protocol. iconic behavior honestly 👑

---

🦋 SYNOPSIS 🦋

enum ishtp_hbm_state {
    ISHTP_HBM_IDLE ,
    ISHTP_HBM_START ,
    ISHTP_HBM_STARTED ,
    ISHTP_HBM_ENUM_CLIENTS ,
    ISHTP_HBM_CLIENT_PROPERTIES ,
    ISHTP_HBM_WORKING ,
    ISHTP_HBM_STOPPED

};

like, look at her. seven states. all caps. all slay. no cap, this is the whole enum laid out exactly as it lives in the header 💖

🎀 Constants 🎀

each one of these is a moment in the protocol's little life story, ok? here's the full cast:

• ISHTP_HBM_IDLE — the protocol hasn't started yet. she's just chilling. not started. we love a calm beginning 🌸
• ISHTP_HBM_START — the start request message was sent. like, she texted first. bold move 💅
• ISHTP_HBM_STARTED — hmm. the docs literally say -- undescribed -- so... yeah. that's all we got. no description. it's giving mysterious main character energy 🕵️‍♀️
• ISHTP_HBM_ENUM_CLIENTS — the enumeration request was sent. she's out here asking who's who 🦋
• ISHTP_HBM_CLIENT_PROPERTIES — acquiring clients properties. yes bestie, we're getting the properties. collecting the lore 📋✨
• ISHTP_HBM_WORKING — another -- undescribed --. the docs said nothing. she just works 💀
• ISHTP_HBM_STOPPED — and -- undescribed -- again. stopped. done. that's it. we don't know more and I refuse to make it up 🙈

fr fr, three of these have no description in the source, and I'm not gonna invent one for you. iykyk. that's just what the page says 🫶
