💖 bl_enter_powerdown(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for bl_enter_powerdown, and no cap, it's lowkey one of those tiny functions that does something kind of iconic: it tells the CPU to go have a little nap in a very specific state 😴👑

🌸 NAME 🌸

bl_enter_powerdown — Programs CPU to enter the specified state

✨ SYNOPSIS ✨

__cpuidle int bl_enter_powerdown (struct cpuidle_device *dev , struct
       cpuidle_driver *drv , int idx );

🎀 ARGUMENTS 🎀

• dev — the cpuidle device, aka the thing we're about to send to sleep 🛌
• drv — The target state to be programmed 💫
• idx — state index, the little number that says which state, iykyk 🔢

🦋 DESCRIPTION 🦋

So here's the vibe check: this one gets called from the CPUidle framework, and its whole main character job is to program the device to the specified target state — the one the governor picked out 👑✨ Like, the governor chooses, and bl_enter_powerdown makes it happen. Periodt.
