tb_switch_suspend(9)

👑 tb_switch_suspend 👑

okay so bestie, this page is from the Kernel API Manual, and it's the little sleep-time ritual for a Thunderbolt switch 😴✨ no gatekeeping, every detail is staying right here.

---

✨ NAME ✨

tb_switch_suspend — Put a switch to sleep 💤

---

🌸 SYNOPSIS 🌸

void tb_switch_suspend (struct tb_switch *sw , bool runtime );

---

🎀 ARGUMENTS 🎀

• sw — Switch to suspend; literally the router you're tucking in 💤
• runtime — Is this runtime suspend or system sleep? that's the vibe check for wakes ✨

---

🦋 DESCRIPTION 🦋

So it Suspends router and all its children — the whole little tree gets the nap memo, no cap 😭💖

Then it Enables wakes according to value of runtime, and after that it sets sleep bit for the router. Very demure, very mindful, very sleepy 🎀

And if sw is host router, the domain is ready to go to sleep once this function returns — that's it, that's the whole glow-up 🌙✨
