ENUM MLXREG_HOTPLUG_KIND(9)

💖 NAME 💖

enum mlxreg_hotplug_kind — kind of hotplug entry. This is the Kernel API Manual page for enum mlxreg_hotplug_kind(9), bestie, and we’re about to get you fully caught up on every single constant. 💅✨

🎀 SYNOPSIS 🎀

She’s an enum, and the whole cast is listed exactly like this:

enum mlxreg_hotplug_kind {
    MLXREG_HOTPLUG_DEVICE_NA ,
    MLXREG_HOTPLUG_LC_PRESENT ,
    MLXREG_HOTPLUG_LC_VERIFIED ,
    MLXREG_HOTPLUG_LC_POWERED ,
    MLXREG_HOTPLUG_LC_SYNCED ,
    MLXREG_HOTPLUG_LC_READY ,
    MLXREG_HOTPLUG_LC_ACTIVE ,
    MLXREG_HOTPLUG_LC_THERMAL

};

✨ Constants ✨

Okay so here’s the whole hotplug kind roster — no skips, no “you’ll figure it out later,” periodt:

• MLXREG_HOTPLUG_DEVICE_NA — do not care; literally the “not my problem” constant, and honestly same. 🫶
• MLXREG_HOTPLUG_LC_PRESENT — the entry for line card presence in/out events; she’s tracking whether the line card is here or ghosted. 👀
• MLXREG_HOTPLUG_LC_VERIFIED — the entry for line card verification status events coming after line card security signature validation — yes, after the security signature check, no cap. 🔐
• MLXREG_HOTPLUG_LC_POWERED — the entry for line card power on/off events — powering up, powering down, the whole glow-up. ⚡
• MLXREG_HOTPLUG_LC_SYNCED — the entry for line card synchronization events, coming after hardware-firmware synchronization handshake — hardware and firmware said “let’s sync” first. 🤝
• MLXREG_HOTPLUG_LC_READY — the entry for line card ready events, indicating line card PHYs ready / unready state — ready or not, here she comes. 💫
• MLXREG_HOTPLUG_LC_ACTIVE — the entry for line card active events, indicating firmware availability / unavailability for the ports on line card — firmware said “I’m available” or “I’m not,” and the ports are listening. 🎧
• MLXREG_HOTPLUG_LC_THERMAL — the entry for line card thermal shutdown events; a positive event indicates that the system should power off the line card for which this event has been received — like, actually power it off, bestie, this is a safety vibe. 🔥
