rpmh_rsc_write_next_wakeup(9)

💅 rpmh_rsc_write_next_wakeup(9) — like, the Kernel API Manual page, bestie 🎀

okay so this is a page from the Kernel API Manual, and it's literally called rpmh_rsc_write_next_wakeup(9). yes that's a mouthful, we're gonna get through it together 🫶

---

✨ NAME ✨

rpmh_rsc_write_next_wakeup — writes the next wakeup into CONTROL_TCS. that's it. that's the whole vibe. 🦋

---

🌸 SYNOPSIS 🌸

void rpmh_rsc_write_next_wakeup (struct rsc_drv *drv );

like, it returns nothing (void), it takes one thing, and its name is a whole paragraph. iconic honestly 👑

---

⭐ ARGUMENTS ⭐

• drv — the controller. yep, that's the one (1) argument. she's the controller. main character energy fr fr 💅

---

🔥 DESCRIPTION 🔥

so here's the tea ☕ — when someone calls this function, what it writes depends on where you're calling it from, and that's the whole plot:

• called from suspend → it writes the maximum wakeup cycles. like, going all out, the max.
• called from idle → it writes the earliest hrtimer wakeup instead. different vibe, different number. 🕐

same function, two completely different moods depending on context. no cap. lowkey obsessed with how that works ngl ✨

that's seventeen friends and every single one of them is a whole (9) page. the friend group is large, and honestly? goals 🌈

💀 real talk tho: this page tells you exactly two behaviours — max wakeup cycles from suspend, earliest hrtimer wakeup from idle. don't go reading anything else into it, i'm not gonna make stuff up for you, that's not the vibe 🙈

and that's the page!! mwah, love u, go read ./drivers/soc/qcom things 💜 — this lil writeup dropped October 2026, from the source path ./drivers/soc/qcom, and it's all about rpmh_rsc_write_next_wakeup(9) ✨🎀🫶 you're gonna slay this
