cpuidle_gove..._latency_req(9)

💖 cpuidle_gove..._latency_req(9) 💖

okay so real talk, bestie — this is a page from the Kernel API Manual, and it's, like, adorably short. We're talking three sections and a dream. But every crumb is here, no cap. Let's get into it ✨

---

✨ NAME ✨

cpuidle_governor_latency_req — compute a latency constraint for CPU 🧚

Like, that's the whole mission statement. It computes a latency constraint, and it does it for a CPU. Iconic, focused, no filler. Periodt.

---

🌸 SYNOPSIS 🌸

s64 cpuidle_governor_latency_req (unsigned int cpu );

bestie look at that signature. It hands you back an s64, and it wants an unsigned int cpu in return. Balanced. Symmetrical. A little trading situation between you and the kernel 🫶

---

🎀 ARGUMENTS 🎀

• cpu — target CPU 🎯

That's it. That's the whole cast of characters. One (1) argument. She's low maintenance and we respect that 💅

---

🦋 SEE ALSO 🦋

• the kernel file ./drivers/cpuidle/governor.c — that's where the actual source lives, go snoop 👀
• cpuidle_find_governor(9)
• cpuidle_switch_governor(9)
• cpuidle_register_governor(9)

the whole governor friend group, fr fr. iykyk 🌈

ngl there's not a single warning, exit status, or env var on this page — so there's literally nothing sketchy to flag. just vibes and one latency constraint 💀

and that's the page, bestie! 🌸 this little cutie comes to you from ./drivers/cpuidle, dated October 2026 — main character energy from the cpuidle directory, as always 👑💖
