💅 cps_pm_enter_state(9) 💅

okay bestie, welcome to the Kernel API Manual — this one is short, iconic, and all about entering a PM state. No cap. ✨

🎀 NAME 🎀

cps_pm_enter_state — enter a PM state. That is the whole assignment. 💖

✨ SYNOPSIS ✨

int cps_pm_enter_state (enum cps_pm_state state );

🌸 ARGUMENTS 🌸

• state — the state to enter. Yep, bestie, that's literally the value you're handing over. 🫶

🦋 DESCRIPTION 🦋

Call this and it enters the given PM state. Main character energy, honestly. 👑

Here's the coupled-coherence tea: if coupled_coherence is non-zero, then it is expected that this function be called at approximately the same time on each coupled CPU. Coordinate the group chat, okay? 🫶

Return vibe check: it returns 0 on successful entry & exit, otherwise -errno. If it's not 0, that's the "nope" branch — handle it. 💅
