okay so bestie, welcome to the Kernel API Manual ✨ this one's a kernel function page and it's gonna be so chill, i promise 🫶

---

🌸 NAME 🌸

acpi_processor_setup_cpuidle_dev — sets up the CPUIDLE device, like, the per-cpu data situation 💫

fr fr that's the whole vibe: it configures the CPUIDLE device, i.e. the per-cpu data. no cap.

---

✨ SYNOPSIS ✨

void acpi_processor_setup_cpuidle_dev (struct acpi_processor *pr ,
struct cpuidle_device *dev );

look at her go 😭 she's void, she takes two pointers, she does not return anything. iconic behaviour honestly.

---

🎀 ARGUMENTS 🎀

• pr — the ACPI processor 👑 like, the processor itself, the main character
• dev — the cpuidle device 🦋 the device bestie that's getting set up

lowkey a reminder: this page is all about configuring the per-cpu CPUIDLE device data — that's it, that's the whole job 💅 don't go inventing extra behaviour, she's booked and busy.

and that's a wrap, bestie!! 🎀 this page lives over in ./drivers/acpi, dated October 2026, and honestly? she ate. periodt. 🌈⭐💜
