💅 acpi_idle_lpi_enter(9) — Kernel API Manual realness 💅

okay so bestie, this is the Kernel API Manual page for acpi_idle_lpi_enter(9). It’s the function that enters an ACPI any LPI state. That’s the whole assignment. No cap. ✨

✨ NAME ✨

acpi_idle_lpi_enter — enters an ACPI any LPI state.

🦋 SYNOPSIS 🦋

int __cpuidle acpi_idle_lpi_enter (struct cpuidle_device *dev , struct cpuidle_driver *drv , int index );

🫶 ARGUMENTS 🫶

okay so the function takes three things, and every single one is doing main character work:

• dev — the target CPU. That’s the CPU bestie we’re aiming at. 🎯
• drv — the cpuidle driver containing cpuidle state info. It’s giving “driver with the state info.” 💅
• index — index of target state. That’s how we point at the exact state. 👑

🎀 RETURN 🎀

0 for success, or a negative value for error. So 0 is the slay, and a negative value is the “bestie no” — handle it and don’t pretend you didn’t see it. 😭
