💅 gain_get_scale_fraction(9)

okay so bestie, welcome to the Kernel API Manual — this is a (9) page, which means it's a kernel-internal thing, not like a command you type. we're doing gain_get_scale_fraction today and honestly it's giving very "math girlie does driver plumbing" energy 🧮✨

🌸 NAME 🌸

gain_get_scale_fraction — get the gain or time based on scale and known one 🎀

like, you hand it a scale, you hand it the thing you already know, and it figures out the thing you don't. lowkey iconic.

✨ SYNOPSIS ✨

int gain_get_scale_fraction (const u64 max , u64 scale , int known , int
*unknown );

🦋 ARGUMENTS 🦋

  • max — the maximum linearized scale. and like, the manpage gives the cutest example so i'm keeping it: when scale is created in magnitude of NANOs and max scale is 64.1 — the linearized scale is 64 100 000 000. no cap, that's a lot of zeroes 💀
  • scale — the linearized scale we're computing the gain/time for. this is the main character input fr.
  • known — either the integration time or the gain, depending on which one you already know. pick a lane, bestie 🫶
  • unknown — pointer to the variable where the computed gain/time gets stored 🌟

💖 DESCRIPTION 💖

so this is an internal helper for computing the unknown fraction of the total gain. yes, internal — it's not out here for public consumption, it's a behind-the-scenes situation 🙈

what it does: compute either gain or time based on scale and either the gain or the time, depending on which one is known. that's it. that's the whole vibe. one known, one unknown, scale in the middle, slay 🔥

🌈 RETURN 🌈

0 on success. that's the whole section, she's short and she knows it 👑

and here's the whole extended friend group, all (9)s, all here, all accounted for, i did not skip a single one because i would never 😤:

and that's the page!! 🎀 this little cutie shipped out of ./drivers/iio, dated October 2026, under the very glamorous title gain_get_scale_fraction(9). go forth and linearize your scales bestie, ily 💜🦋
