xe_pm_runtime_resume(9)

✨ xe_pm_runtime_resume ✨ (that's the page, bestie — live from the Kernel API Manual 💅)

okay so picture this: it's giving kernel-docs-but-make-it-cute. this is xe_pm_runtime_resume(9), and yes it's a real function in the Kernel API Manual, we're not making it up 🫶

🌸 NAME 🌸

xe_pm_runtime_resume — literally just Waking up from D3hot/D3Cold. that's the whole vibe. the device was napping in a deep power state and this is the glow-up moment where it comes back 😴➡️✨

---

🎀 SYNOPSIS 🎀

int xe_pm_runtime_resume(struct xe_device *xe);

one function, one argument, returns an int. simple. iconic. no cap 💅

---

💖 ARGUMENTS 💖

• xe — the xe device instance. like, the device. your main character. the one you're waking up 🦋

⭐ DESCRIPTION ⭐

so what does it actually do? it wakes stuff up from D3hot/D3Cold, that's the whole thing, and then it tells you how it went:

• returns 0 for success 🎉 (we love a zero, a zero is a win)
• returns a negative error code otherwise 😭 (not a win, but at least it's honest)

fr fr that's the entire description — no hidden lore, no extra caveats, this one's a short king 👑
