🌸 hibernation_restore(9) 🌸

okay bestie, so this is a page from the Kernel API Manual and it's literally about waking your computer up from a nap so deep it forgot everything. we're talking hibernation vibes only. let's get into it 💅

---

✨ NAME ✨

hibernation_restore — Quiesce devices and restore from a hibernation image.

like, you put all the devices to sleep and then poof bring the whole system back from a saved image. it's giving resurrection era fr fr 🦋

---

💻 SYNOPSIS 💻

int hibernation_restore (int platform_mode );

---

🎀 ARGUMENTS 🎀

• platform_mode — If set, use platform driver to prepare for the transition. so like, if this is nonzero, the platform driver gets to handle the prep work. no cap, that's the whole vibe. 👑

---

🌈 DESCRIPTION 🌈

okay so this routine must be called with system_transition_mutex held. that's not a suggestion bestie, that's the law. do not skip this step, i'm literally begging. 😭

if it's successful, control reappears in the restored target kernel in hibernation_snapshot. so like, you don't come back here, you come back there. it's a whole different main character moment. 💀
