dev_pm_genpd_resume(9)

💖 dev_pm_genpd_resume — the dev_pm_genpd_resume(9) glow-up guide 💖

Okay bestie, buckle up, because this is the kernel API manual page for dev_pm_genpd_resume(9) and honestly? she's short but she's important. Let's get into it. ✨

---

🌸 NAME 🌸

dev_pm_genpd_resume — synchronously try to resume the genpd for @dev. That's it, that's the whole name, and yes, the "synchronously" is doing a lot of heavy lifting there, iykyk. 💅

---

🦋 SYNOPSIS 🦋

void dev_pm_genpd_resume (struct device *dev );

Look at her. Returns void. Doesn't even hand you an error code back. Iconic, lowkey terrifying. 🫶

---

🎀 ARGUMENTS 🎀

• dev — the device that's attached to the genpd, the one that needs to be resumed. That's your main character right there. 👑

---

⭐ DESCRIPTION ⭐

So here's the tea: this routine should typically be called for a device that needs to be resumed during the syscore resume phase. Like, that's her whole moment to shine. ✨

She may also be called during suspend-to-idle, to resume a corresponding CPU device that's attached to a genpd. So yes, there are two vibes she shows up for. Versatile queen. 🌈

ngl, the word "synchronously" in the NAME is not a suggestion — this thing does the resume right then and there, no queuing, no "I'll get to it later". Plan accordingly bestie 💀
