genpd_runtime_suspend(9)

✨ genpd_runtime_suspend(9) ✨

okay so bestie, welcome to the genpd_runtime_suspend manual page — it's part of the Kernel API Manual and honestly it's giving "small function, big responsibilities" energy 💅

---

💖 NAME 💖

genpd_runtime_suspend — literally just suspending a device that belongs to an I/O PM domain, no cap.

---

🎀 SYNOPSIS 🎀

int genpd_runtime_suspend (struct device *dev );

---

🌸 ARGUMENTS 🌸

• dev — the device we're suspending. that's it. that's the whole argument. she's lowkey simple like that 🦋

---

🧚 DESCRIPTION 🧚

okay so here's the vibe: this function carries out a runtime suspend of a device, but — and this is the important part, don't @ me — it does so under the assumption that the device's pm_domain field points to the domain member of an object of type struct generic_pm_domain representing a PM domain made up of I/O devices. so yeah, that assumption is load-bearing, bestie. it's giving "trust but verify" but mostly just "trust" 🙈✨
