enter_state(9)

💤 enter_state(9) 💤

okay so welcome to the Kernel API Manual entry for enter_state(9), bestie — this is the little kernel helper that does the common work needed to enter a system sleep state. main character energy for suspend, honestly 🫶✨

---

🌸 NAME 🌸

enter_state — do common work needed to enter system sleep state. periodt 💅

---

✨ SYNOPSIS ✨

int enter_state (suspend_state_t state );

---

🎀 ARGUMENTS 🎀

• state — the system sleep state to enter. that's the whole vibe check for this argument 💖

---

🦋 DESCRIPTION 🦋

okay so first things first: enter_state makes sure that no one else is trying to put the system into a sleep state. if that's not the case, it fails — no cap, that's the rule 😭

otherwise, it prepares for system suspend, makes the system enter the given sleep state, and cleans up after wakeup. literally the full suspend-era pipeline: prep, enter, cleanup, slay ✨🔥
