devfreq_update_interval(9)

📦 version 7.3.1, in nixpkgs unstable

💅 devfreq_update_interval — like, the Kernel API Manual one, bestie

Okay so before we even start: this is a page from the Kernel API Manual (section 9, the kernel-functions girlies ✨). Sit down, grab a strawberry drink 🍓, and let's get into it.

✨ NAME ✨

devfreq_update_interval — update the device devfreq monitoring interval. That's it, that's the whole vibe check. 🎀

🦋 SYNOPSIS 🦋

void devfreq_update_interval (struct devfreq *devfreq , unsigned int
*delay );

Note the return type, bestie: void. She does the thing and she leaves. No return value, no notes, no follow-up text. 👑

🌸 ARGUMENTS 🌸

  • devfreq — the devfreq instance. Your main character struct, fr fr. 💖
  • delay — the new polling interval that's getting set. It's an unsigned int * pointer, so yes, pointer, not the bare number. 🫶

🧚 DESCRIPTION 🧚

So this is a helper function, and her whole job is setting a new load monitoring polling interval. That's it — she's the glow-up for your polling cadence. ✨

The tea on when you call her: this function is meant to be called from the governor, in response to the DEVFREQ_GOV_UPDATE_INTERVAL event. So the governor's like "hey bestie, new interval please" and this function is the one who actually handles it. iykyk. 🔥

No cap, it's genuinely that simple. She's a helper. She helps. Periodt. 💅

Go read the others too, bestie, don't leave them on read. 📖💀

And that's the page!! 🎀 Sign-off time: this lil masterpiece lives in ./drivers/devfreq, and it's dated October 2026. October 2026?? She's from the future, she's a time traveler, we love a mysterious queen. 🦋👑 Bye bestie, go update some intervals! 💖
