cpuidle_reflect(9)

📦 version 7.3.1, in nixpkgs unstable

💅 cpuidle_reflect — ok so hear me out bestie

This is a page from the Kernel API Manual, section 9 (that's the kernel API girlies, iykyk). And the function we're vibing with today is cpuidle_reflect ✨

🌸 NAME 🌸

cpuidle_reflect — literally tells the underlying governor what state we were just in 🫶

Like, the governor's been sitting there wondering "bestie where did you go" and this is the function that goes "okay so. here's where I was." No cap, that's the whole job.

🦋 SYNOPSIS 🦋

void cpuidle_reflect (struct cpuidle_device *dev , int index );

That's it. Two things in, nothing out. It's giving "void, returns nothing, just vibes" 💀

🎀 ARGUMENTS 🎀

  • dev — the cpuidle device 💖 like, the actual device we're talking about here
  • index — the index in the idle state table ⭐ the little number that says which state we were in

Two arguments, both iconic, both necessary. Periodt.

🔥 SEE ALSO 🔥

Ok so the kernel file for all of this lives at ./drivers/cpuidle/cpuidle.c and honestly the whole friend group lives there. Go say hi to:

That's twenty of them, bestie. Twenty. The way this whole module is one big found family 😭💜

Ngl this page is short but she ate. Sometimes a manpage doesn't need 40 options — sometimes she just needs to tell the governor where she's been and go home 🧚

Ok so that's the whole page! Shoutout to ./drivers/cpuidle for hosting all this, and this edition is dated October 2026 — mark your calendars babes 📅✨ Love u, stay idle, stay iconic 💅👑
