💅 dfll_calc_monitored_rate(9) 💅

okay so this is a page straight out of the Kernel API Manual — bestie, it's dfll_calc_monitored_rate(9), and we're about to make it make sense. no cap, it's shorter than your attention span but it's lowkey important. 🦋

✨ NAME ✨

dfll_calc_monitored_rate — the little function that converts a DFLL_MONITOR_DATA_VAL rate into an actual real freq. it's giving translator energy, honestly. 💅

---

🌸 SYNOPSIS 🌸

u64 dfll_calc_monitored_rate (u32 monitor_data , unsigned long ref_rate );

---

🎀 ARGUMENTS 🎀

• monitor_data — this is the value you read out of the DFLL_MONITOR_DATA_VAL bitfield. literally just the raw number, hand it over. 🍓
• ref_rate — the DFLL reference clock rate. that's the unsigned long one, yes ma'am. ⭐

---

🧚 DESCRIPTION 🧚

so what it does: it takes monitor_data — which is chilling in DFLL_MONITOR_DATA_VAL units — and converts it into cycles per second. that's it. that's the whole vibe.

and then? it returns the converted value. iconic. returns it as a u64, so it's not being subtle about it. 🫶
