💤 wakeup_source_deactivate(9) — the Kernel API Manual glow-up

Okay bestie, so this one lives in the Kernel API Manual and it's literally called wakeup_source_deactivate 💅 yes, the name is giving exactly what it is — it's the "okay we're done here, you can stop being awake now" call.

✨ NAME ✨

wakeup_source_deactivate — mark the given wakeup source as inactive, periodt. 🎀

🦋 SYNOPSIS 🦋

void wakeup_source_deactivate (struct wakeup_source *ws );

That's it. It returns void, so no vibe check on the way out — nothing to check, nothing to unwrap, no cap. 🫶

🌸 ARGUMENTS 🌸

  • ws — the wakeup source you're handling. That's the whole cast of this show, she's the main character. 👑

💖 DESCRIPTION 💖

So here's the tea, bestie: wakeup_source_deactivate does two things at once and honestly? iconic multitasking. ⭐

  • It updates ws's statistics — gotta keep the receipts. 📊
  • It notifies the PM core that the wakeup source has become inactive — like texting the group chat "k I'm done" so nobody's left waiting on you. 😭

And the way it does that notify is very specific, so don't let it slide: it decrements the counter of wakeup events being processed, and it increments the counter of registered wakeup events. Two counters, opposite directions, one function. It's giving balance. 🧚✨

Heads up, bestie — the description says exactly those two counter updates, so don't go claiming this does anything else. No extra lore, no hidden side quests. 💀

🔥 SEE ALSO 🔥

The kernel file where all this lives is ./drivers/base/power/wakeup.c, and here's the whole friend group — every single one, don't leave anybody on read:

🎀 ngl that's a lot of cross-references, but that's just how deep the power-management friend group runs. iykyk.

Alright bestie, that's the whole page 💜 — sourced from ./drivers/base/power, and this little gem is dated October 2026 (yes, future-dated, she's ahead of her time ✨). Now go forth and deactivate those wakeup sources responsibly, mwah 🫶🌈
