genpd_resume_noirq(9)

💖 genpd_resume_noirq — a kernel API manual moment 💖

okay so bestie, welcome to the genpd_resume_noirq(9) page, straight out of the Kernel API Manual ✨ this one's short and sweet and honestly kind of a main character in the noirq resume arc 🦋

---

🌸 NAME 🌸

genpd_resume_noirq — Start of resume of device in an I/O PM domain.

like, the beginning of the resume journey for a device that lives in an I/O power-management domain, no cap 💅

---

✨ SYNOPSIS ✨

int genpd_resume_noirq (struct device *dev );

that's the whole vibe: it takes a struct device * and hands you back an int 🫶

---

🎀 ARGUMENTS 🎀

• dev — Device to resume. that's it, that's the whole argument bestie, one device, iconic 👑

---

🔥 DESCRIPTION 🔥

So here's what's going down: it restores power to the device's PM domain, if necessary, and then starts the device 💖

lowkey the "if necessary" is doing a lot of work there and we love her for it — no wasted power moves, periodt ⭐

ngl this is the noirq flavour of resume, so just know it's happening in that context, okay? 😭
