STRUCT CLK_FIXED_RATE(9)

💖 struct clk_fixed_rate(9) 💖

okay so bestie, welcome to the Kernel API Manual — we're talking about struct clk_fixed_rate, aka the fixed-rate clock, and honestly? it's giving "I never change and I'm proud of it." a whole icon.

---

✨ SYNOPSIS ✨

like, here's the shape of it, fr fr:

struct clk_fixed_rate {
    struct clk_hw hw;
    unsigned long   fixed_rate;
    unsigned long   fixed_accuracy;
    unsigned long   flags;
 };

that's the whole vibe. four fields. no notes. 💅

🎀 Members 🎀

• hw — the handle between the common interfaces and the hardware-specific ones. like the go-between, the mutual friend, the one who translates. 🫶
• fixed_rate — the constant frequency of the clock. it's fixed. it's a rate. it does not switch up on you, not ever. 👑
• fixed_accuracy — the constant accuracy of the clock in ppb (parts per billion). yes, per billion, we're being precise out here. ✨
• flags — hardware specific flags. the little extra personality settings, iykyk. 🌸

💜 Description 💜

so the flags section, bestie — there is literally one flag and it's kind of a big deal:

• CLK_FIXED_RATE_PARENT_ACCURACY — use the accuracy of the parent clk instead of what's set in fixed_accuracy. so like, you could hardcode your own accuracy, but this flag says "nah, let me borrow my parent's." respectful. humble. love that for it. 🦋

ngl, that's the entire description. one flag. iconic minimalism. 🎀

and that's the page, bestie! this little beauty lives in ./include/linux and the version/date situation is October 2026 — so yeah, future-coded of it. mwah, go fix your clocks. 💅✨🎀
