dw_apb_clocksource_start(9)

💅 dw_apb_clocksource_start

okay bestie, so this one lives in the Kernel API Manual (section 9, the kernel-functions girlies ✨) and it's called dw_apb_clocksource_start. that's the whole name. iconic, no notes. 🎀

---

✨ SYNOPSIS ✨

void dw_apb_clocksource_start (struct dw_apb_clocksource *dw_cs );

like, that's it. no return value (void), no drama, just vibes and a single pointer. 💅

---

🌸 ARGUMENTS 🌸

• dw_cs — the clocksource you wanna start. literally the main character of this function. hand it over and she's off. 👑

---

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this is what you call to start the clocksource counting before registration. yes, before. like, you get the timer ticking first and then you go do the official paperwork, iykyk.

and why would you do that? because starting it early is what lets you enable calibration of timers 🔥. that's the whole point, fr fr. clock go brrr so the calibration can actually happen. 🫶
