ENUM IPC_MEM_DEV_PM_STATE(9)

💅 enum ipc_mem_dev_pm_state(9) ✨

okay so this is a page from the Kernel API Manual bestie, and it's literally all about enum ipc_mem_dev_pm_state — no cap 🫶

🌸 NAME 🌸

enum ipc_mem_dev_pm_state — the possible states of the DEVICE SLEEP finite state machine ✨ like, every vibe your device's sleep state machine can possibly be in, all listed out 💖

🦋 SYNOPSIS 🦋

enum ipc_mem_dev_pm_state {
    IPC_MEM_DEV_PM_ACTIVE ,
    IPC_MEM_DEV_PM_SLEEP ,
    IPC_MEM_DEV_PM_WAKEUP ,
    IPC_MEM_DEV_PM_HOST_SLEEP ,
    IPC_MEM_DEV_PM_ACTIVE_WAIT ,
    IPC_MEM_DEV_PM_FORCE_SLEEP ,
    IPC_MEM_DEV_PM_FORCE_ACTIVE

};

🎀 Constants 🎀

bestie here's the full lineup, every single one, no skips 💅

• IPC_MEM_DEV_PM_ACTIVE — this one is the initial power management state, the main character energy of the enum 👑 it's also the IRQ(struct ipc_mem_device_info: device_sleep_notification) and DOORBELL-IRQ-HPDA(data) values.
• IPC_MEM_DEV_PM_SLEEP — the PM state for sleep 😴 that's it, that's the whole vibe.
• IPC_MEM_DEV_PM_WAKEUP — this is the DOORBELL-IRQ-DEVICE_WAKE(data) one ⭐
• IPC_MEM_DEV_PM_HOST_SLEEP — and this is the DOORBELL-IRQ-HOST_SLEEP(data) one 🌙
• IPC_MEM_DEV_PM_ACTIVE_WAIT — local intermediate states, like the hallway between rooms of the state machine 🚪✨
• IPC_MEM_DEV_PM_FORCE_SLEEP — this one's the DOORBELL-IRQ-FORCE_SLEEP 💤
• IPC_MEM_DEV_PM_FORCE_ACTIVE — and this one's the DOORBELL-IRQ-FORCE_ACTIVE 🔥
