genpd_poweroff_noirq(9)

🌸 genpd_poweroff_noirq(9) — Kernel API Manual 🌸

okay bestie, welcome to the genpd_poweroff_noirq(9) page from the Kernel API Manual 💖 this one is short but it's literally about the completion of hibernation, so let's get into it. no cap.

💖 NAME 💖

genpd_poweroff_noirq — completion of hibernation of device in an I/O PM domain. ✨

✨ SYNOPSIS ✨

the signature is giving exactly this, fr fr:

int genpd_poweroff_noirq (struct device *dev );

🎀 ARGUMENTS 🎀

• dev — Device to poweroff. that's it, that's the whole argument list, bestie 🫶

🦋 DESCRIPTION 🦋

okay so the vibe is: stop the device, and remove power from the domain if all devices in it have been stopped. the way that "all devices in it have been stopped" is a whole prerequisite — like, the domain only loses power when every device inside has already been stopped. periodt 💅
