💫 wakeup_source_sysfs_add(9) 💫

okay so bestie, welcome to the Kernel API Manual — this one's a lil function called wakeup_source_sysfs_add, and honestly? it's giving "make my wakeup source visible in sysfs" energy. no cap. ✨

---

🌸 NAME 🌸

wakeup_source_sysfs_add — adds wakeup_source attributes to sysfs. that's the whole vibe. she shows up, she makes files, she leaves. iconic. 💅

---

🦋 SYNOPSIS 🦋

int wakeup_source_sysfs_add (struct device *parent , struct
wakeup_source *ws );

literally just call her with a parent device and a wakeup source and she does the thing. returns an int, so like, pay attention to that. 🫶

---

🎀 ARGUMENTS 🎀

• parent — the Device that the given wakeup source is associated with. and yes, she can be NULL if the source is virtual (a little ghost girl, no physical device, still valid 💀).
• ws — the Wakeup source that's getting added in sysfs. that's the main character right there. 👑

---

🔥 SEE ALSO 🔥

• Kernel file ./drivers/base/power/wakeup_stats.c — go read the source, iykyk 📖
• pm_wakeup_source_sysfs_add(9)
• wakeup_source_sysfs_remove(9) — the breakup arc 😭

---

ngl the parent being NULL thing is the one detail people forget, so like, don't be that person. 🍓

and that's the page!! 💖 this gem lives in ./drivers/base/power, and the version/date stamp on her is October 2026 — so like, yeah, she's from the future, slay. bye bestie, go add some sysfs attributes 🧚‍♀️✨🌸
