__pm_runtime_idle(9)

💖 __pm_runtime_idle(9) 💖

Okay bestie, welcome to the Kernel API Manual page for __pm_runtime_idle 🫶 This is the runtime-idle entry point, and we're gonna get into it.

✨ NAME ✨

__pm_runtime_idle — entry point for runtime idle operations. Periodt ✨

🌸 SYNOPSIS 🌸

int __pm_runtime_idle (struct device *dev , int rpmflags );

🎀 ARGUMENTS 🎀

• dev — the device you're sending the idle notification for 💖
• rpmflags — flag bits 🚩

🦋 DESCRIPTION 🦋

Okay so here's the tea ☕: if the RPM_GET_PUT flag is set, this routine decrements the device's usage count. If that count is larger than zero, it returns immediately. If it becomes negative, it logs a warning, increments the count, and returns an error. Then it carries out an idle notification, and that notification can be either synchronous or asynchronous. Slay 💅

This routine may be called in atomic context if the RPM_ASYNC flag is set, or if pm_runtime_irq_safe has been called. Those are the conditional vibes, so keep them in mind 👑
