ENUM AP_PWRST_TRANS(9)

🦋 enum ap_pwrst_trans(9) 🦋

okay so bestie, welcome to enum ap_pwrst_trans(9) from the Kernel API Manual — yes, that’s literally the manual name, and this page is giving tiny-enum, big-power-transition energy. main character energy fr fr 💅

💖 NAME 💖

enum ap_pwrst_trans — transition states defined in PRCMU firmware. That’s the whole name vibe, no cap.

✨ SYNOPSIS ✨

here’s the exact enum shape, bestie — keep the punctuation, the spaces before the commas, all of it:

enum ap_pwrst_trans {
    PRCMU_AP_NO_CHANGE ,
    APEXECUTE_TO_APSLEEP ,
    APIDLE_TO_APSLEEP ,
    PRCMU_AP_SLEEP ,
    APBOOT_TO_APEXECUTE ,
    APEXECUTE_TO_APDEEPSLEEP ,
    PRCMU_AP_DEEP_SLEEP ,
    APEXECUTE_TO_APIDLE ,
    PRCMU_AP_IDLE ,
    PRCMU_AP_DEEP_IDLE

};

🎀 Constants 🎀

okay here’s the cast, one bullet per constant, literally every single one:

• PRCMU_AP_NO_CHANGE — the manpage says -- undescribed --; no extra lore, ngl.
• APEXECUTE_TO_APSLEEP — Power state transition from ApExecute to ApSleep. slay, a described one.
• APIDLE_TO_APSLEEP — Power state transition from ApIdle to ApSleep.
• PRCMU_AP_SLEEP — literally -- undescribed -- in the source. 🙈
• APBOOT_TO_APEXECUTE — Power state transition from ApBoot to ApExecute.
• APEXECUTE_TO_APDEEPSLEEP — Power state transition from ApExecute to ApDeepSleep.
• PRCMU_AP_DEEP_SLEEP — -- undescribed --, bestie, that’s all it gives us.
• APEXECUTE_TO_APIDLE — Power state transition from ApExecute to ApIdle.
• PRCMU_AP_IDLE — -- undescribed --. iconic mystery behavior, honestly.
• PRCMU_AP_DEEP_IDLE — also -- undescribed --. the lore is not lore-ing. 😭
