💖 genwqe_base_clock_frequency(9) 💖

okay so bestie, welcome to the Kernel API Manual — this lil page is all about genwqe_base_clock_frequency(9) and honestly it's giving "one job, does it well" energy. let's get into it 🎀

---

✨ NAME ✨

genwqe_base_clock_frequency — figure out the base clock frequency of the card 🕐💅

✨ SYNOPSIS ✨

int genwqe_base_clock_frequency (struct genwqe_dev *cd );

like, that's the whole vibe. one function, one arg, no drama (for once) ✨

✨ ARGUMENTS ✨

• cd — the genwqe device descriptor 🫶 that's the thing you hand over so it knows which card we're clock-checking.

🌸 NOTE 🌸

okay so storytime, because this one is lowkey a cautionary tale 👑

from a design perspective, it turned out to be a bad idea to use codes here to specify the frequency/speed values. and why? because an old driver cannot understand new codes — and that's always a problem 😭 like, imagine being handed a menu in a language you don't speak. not slay.

the better move is to measure out the value, or put the speed/frequency directly into a register, because that's always a valid value for old and new software. periodt. 💀✨

fr fr, take the note — codes bad, direct values/measurement good. this is the "learn from our mistakes" moment 🙈

✨ RETURN ✨

the card clock, in MHz 🔥 that's it, that's the tea.
