pm_runtime_enabled(9)

✨ pm_runtime_enabled ✨

okay so this is a page from the Kernel API Manual, bestie — it's pm_runtime_enabled(9) and it's literally the vibe-check function for runtime power management 💅

🌸 NAME 🌸

pm_runtime_enabled — check if runtime PM is enabled.

🦋 SYNOPSIS 🦋

bool pm_runtime_enabled (struct device *dev );

🎀 ARGUMENTS 🎀

• dev — the target device. like, the actual device you're asking about 🫶

💜 DESCRIPTION 💜

Returns true if runtime PM is enabled for dev, or false otherwise. That's it. That's the whole thing. iconic, honestly ✨

⚠️ but bestie, listen — the return value of this function can only be trusted if it's called under the runtime PM lock of dev, OR under conditions in which runtime PM cannot be either disabled or enabled for dev. no cap. if you're out here calling it raw with no lock and no guarantee, the answer you get back is giving ✨delusion✨, not truth 😭
