power_down(9)

💖 power_down(9) — Kernel API Manual 💖

Okay bestie, welcome to power_down(9) from the Kernel API Manual — the page that's literally about telling the machine to go night-night for hibernation. 💤✨

🌸 NAME 🌸

power_down — shut the machine down for hibernation. 💤👑

✨ SYNOPSIS ✨

void power_down (void );

🎀 ARGUMENTS 🎀

• void — no arguments, bestie. Not a single one. 🫶

🦋 DESCRIPTION 🦋

So here's the vibe: power_down uses the platform driver — if it's configured — to put the system into the sleep state that corresponds to hibernation. 💤

It can also try to power the system off or reboot it, depending on the value of hibernation_mode. That's the whole plot, no cap. 👑🔥
