genpd_power_on(9)

💖 genpd_power_on(9) 💖

okay bestie, so this is a page from the Kernel API Manual, and it's literally about waking a power domain back up. no cap, it's giving "rise and grind" but for silicon. ✨

---

🌸 NAME 🌸

genpd_power_on — restore power to a given PM domain and its parents. yes, and its parents, because nobody powers up alone in this family. 🫶

---

✨ SYNOPSIS ✨

int genpd_power_on (struct generic_pm_domain *genpd , unsigned int depth
);

like, it takes two things and gives you back an int. slay.

---

🎀 ARGUMENTS 🎀

• genpd — the PM domain you wanna power up. the main character of this call, fr fr. 👑
• depth — the nesting count for lockdep. it's the little number that keeps lockdep from getting confused, iykyk. 🔥

---

🦋 DESCRIPTION 🦋

so here's the vibe: genpd_power_on restores power to genpd and all of its parents, so that it's actually possible to resume a device that belongs to it. the way that it walks the whole parent chain — obsessed. 💅

no power, no resume. it's literally that simple. ⭐

and that's the page!! 💜 this lil icon came out of ./drivers/pmdomain, dated October 2026, and it ate, no crumbs. 🍓🧚 go power on those domains, bestie. 🎀
