wakeup_source_register(9)

💖 wakeup_source_register(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for wakeup_source_register(9) — yes that's the whole title, it's giving "I'm the main character of the power-management subsystem" and honestly? it ate. 🎀

---

✨ NAME ✨

wakeup_source_register — Create wakeup source and add it to the list.

like literally that's the whole job. it makes one and yeets it onto the list. no cap. 💅

---

🌸 SYNOPSIS 🌸

struct wakeup_source * wakeup_source_register (struct device *dev ,
       const char *name );

she takes two things and gives you back a struct wakeup_source *. iconic behaviour tbh. 🦋

---

💜 ARGUMENTS 💜

• dev — the Device this wakeup source is associated with (or NULL if virtual). so like, if your wakeup source doesn't have a device bestie to hang with, you pass NULL and she's virtual. lowkey valid. 🫶
• name — the Name of the wakeup source to register. give her a name, she deserves one, she's a whole individual. ⭐

---

🔥 SEE ALSO 🔥

Kernel file ./drivers/base/power/wakeup.c — that's where she lives, that's her home address, go visit her. 🏡

ok real talk for one sec: read the actual kernel docs before you go poking at power management, because sleeping/waking is a whole ✨vibe✨ and you don't wanna mess it up. 💀

alright that's the page!! brought to you fresh from ./drivers/base/power, dated October 2026, and she's serving wakeup_source_register(9) realness. mwah 💋🦋✨🍓💖
