cpuidle_coupled_get_state(9)

💤 cpuidle_coupled_get_state(9) — like, the kernel API manual bestie 💤

okay so this is a page from the Kernel API Manual, and the star of the show is cpuidle_coupled_get_state. she's a little function with a big job and honestly? she ate. ✨

🌸 NAME 🌸

cpuidle_coupled_get_state — determine the deepest idle state 💤👑

🦋 SYNOPSIS 🦋

int cpuidle_coupled_get_state (struct cpuidle_device *dev , struct
       cpuidle_coupled *coupled );

🎀 ARGUMENTS 🎀

• dev — the struct cpuidle_device for this cpu, iykyk 🫶
• coupled — the struct coupled that contains the current cpu 👑

💅 DESCRIPTION 💅

Returns the deepest idle state that all coupled cpus can enter. no cap, that's literally it — she checks what everyone in the couple can agree on and hands you back the deepest nap they can all take together 🌈😴

fr fr, "deepest" here means the whole coupled group has to be able to go there — it's a group decision, not a solo vibe check 💀
