STRUCT CLK_FIXED_FACTOR(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct clk_fixed_factor(9) 💅

okay bestie, welcome to the Kernel API Manual page for struct clk_fixed_factor — it's a whole vibe, let's get into it 🫶

🌸 NAME 🌸

struct clk_fixed_factor — a clock that's literally just a fixed multiplier and divider, no cap 💖

✨ SYNOPSIS ✨

struct clk_fixed_factor {
    struct clk_hw   hw;
    unsigned int    mult;
    unsigned int    div;
    unsigned long   acc;
    unsigned int    flags;
 };

🎀 Members 🎀

  • hw — the handle between the common interfaces and the hardware-specific ones, yep that's the whole job 🦋
  • mult — the multiplier. it multiplies. iconic behavior honestly ✨
  • div — the divider. it divides. balance 💅
  • acc — fixed accuracy, in ppb (that's parts per billion, iykyk) ⭐
  • flags — flags that modify the behavior 👑

🔥 Description 🔥

So this is a clock with a fixed multiplier and divider — like, the numbers are baked in, fr fr. The output frequency is the parent clock rate divided by div and multiplied by mult. That's it, that's the math 🧮💖

It implements .recalc_rate, .set_rate, .determine_rate and .recalc_accuracy — yes queen, all four 👑

🌈 Flags 🌈

  • CLK_FIXED_FACTOR_FIXED_ACCURACY — uses the value in acc instead of the parent clk accuracy. so like, your accuracy, your rules 💅

💜 SEE ALSO 💜

Kernel file ./include/linux/clk-provider.h — and the clk framework crew, all of them, in order, no skips 🙈:

aaaand that's the page, bestie 🎀 mwah 💋 — this lil writeup lives in ./include/linux under the Kernel API Manual, dated October 2026, and it's titled (you guessed it) struct clk_fixed_factor(9). go forth and clock responsibly 🧚‍♀️💖
