device_wakeup_enable(9)

💖 device_wakeup_enable(9) — the Kernel API Manual, bestie edition ✨

okay so you've wandered into a section 9 manpage, which means we're deep in kernel API territory, and the star of this page is device_wakeup_enable — literally the function that lets a device be a wakeup source. yes, like, the thing that wakes your whole machine up. main character energy fr fr 🌸

---

✨ NAME ✨

device_wakeup_enable — Enable given device to be a wakeup source. 👑

Like… that's it. That's the whole job. You give it a device and it goes "sure babe, you can wake me up" 💅

---

🎀 SYNOPSIS 🎀

int device_wakeup_enable (struct device *dev );

ngl, the return type is int and the arg is a struct device * — copy it exactly when you're writing your code, bestie, don't get creative with it 🙈

---

🦋 ARGUMENTS 🦋

• dev — Device to handle. that's your lil guy. the device you're working with. give it a struct device * and off you go 💖

---

🌈 DESCRIPTION 🌈

Okay so here's what actually goes down: it creates a wakeup source object, registers it, and attaches it to dev. ✨

Three steps, one function call, no cap:

1. create a wakeup source object 🧚
2. register it 📝
3. attach it to dev 🔗

and that's it! that's the whole vibe. your device is now a wakeup source. slay 💅

okay this is the long part and I am NOT skipping a single one of these, because every single reference is part of the lore 🫶 also: the kernel file lives at ./drivers/base/power/wakeup.c — that's where the magic is, iykyk 👀
