cpuidle_cou...o_cpus_ready(9)

🎀 NAME 🎀

okay so bestie, welcome to the Kernel API Manual (section 9, kernel API, we're fancy here) — today's main character is cpuidle_coupled_no_cpus_ready, which literally just checks if no cpus in a coupled set are ready. That's it. That's the whole vibe. 💅

✨ SYNOPSIS ✨

int cpuidle_coupled_no_cpus_ready (struct cpuidle_coupled *coupled );

🫶 ARGUMENTS 🫶

• coupled — the struct coupled that contains the current cpu. yes, it's that one. it's holding your cpu, be nice to it. 🎀

🌸 DESCRIPTION 🌸

Returns true if all of the cpus in a coupled set are out of the ready loop. like, every single one of them has dipped out of the ready loop — not a single one left behind. 👑

ngl the function is int but the description says it "returns true" — that's just how the kernel talks, bestie. don't come for me, I'm just the messenger. 😭

that's the whole page, bestie 💖✨ this lil gem lives in ./drivers/cpuidle, dropped October 2026, and it's filed under cpuidle_cou...o_cpus_ready(9) — yes the title got truncated in the header, no she did not get her full name on the marquee, and honestly? iconic of her. 🦋 periodt.
