ENUM MEI_WDT_STATE(9)

💅 enum mei_wdt_state(9)

okay so bestie, we're in the Kernel API Manual today and this page is literally just a little enum — a baby list of states that the MEI watchdog lives in 🐶💖. No cap, it's short, but every single constant matters, so let's get into it.

🌸 NAME

enum mei_wdt_state — the internal watchdog state. that's it, that's the vibe. it's the mood ring of the watchdog, and the mood is always one of these six ⭐

✨ SYNOPSIS

enum mei_wdt_state {
    MEI_WDT_PROBE ,
    MEI_WDT_IDLE ,
    MEI_WDT_START ,
    MEI_WDT_RUNNING ,
    MEI_WDT_STOPPING ,
    MEI_WDT_NOT_REQUIRED

};

like, look at her. six constants, zero drama 🎀

🦋 Constants

okay so these are the six states and what each one means, fr fr 👑

• MEI_WDT_PROBE — the wd is in the probing stage. it's giving "we're still figuring out if this thing even exists" energy 🕵️‍♀️
• MEI_WDT_IDLE — the wd is idle and not opened. just chilling, not doing anything, main character between scenes 💤
• MEI_WDT_START — the wd was opened and start was called. she's awake now ✨
• MEI_WDT_RUNNING — the wd is expecting keep alive pings. like, she needs attention or she gets dramatic 😭
• MEI_WDT_STOPPING — the wd is stopping and will move to IDLE. bye bestie, we'll see you back in idle 🫶
• MEI_WDT_NOT_REQUIRED — the wd device is not required. not needed, not wanted, respectfully exiting the group chat 💀
