cpuidle_disable_device(9) from the Kernel API Manual — okay bestie, we're diving into CPU idle power management and yes, it's giving kernel-core main character energy 💅✨

💤 NAME 💤

cpuidle_disable_device — disables idle PM for a CPU. no cap, that's the whole flex: idle PM for a CPU gets disabled, periodt 💤🔥

✨ SYNOPSIS ✨

void cpuidle_disable_device (struct cpuidle_device *dev );

🖥️ ARGUMENTS 🖥️

• dev — the CPU 🖥️💅

📝 DESCRIPTION 📝

okay so here's the rule that matters: when this is used externally, the function must be called between cpuidle_pause_and_lock and cpuidle_resume_and_unlock 🚨 Like, do not skip that, bestie — the ordering is literally mandatory. no cap, vibe check passed only if you respect that boundary 🫶
