xe_pm_init(9)

💖 xe_pm_init(9) — like, the Kernel API Manual entry, bestie 💖

okay so picture this: it's a kernel API manual page, it's called xe_pm_init(9), and it's about to tell you how to wake up the Xe power management of your dreams. stay with me, it's gonna slay ✨

🌸 NAME 🌸

xe_pm_init — Initialize Xe Power Management. that's it, that's the whole vibe. short, iconic, to the point 💅

---

🎀 SYNOPSIS 🎀

int xe_pm_init (struct xe_device *xe );

like yes, that's the whole signature. it returns an int, it takes a struct xe_device * named xe. no cap. 🫶

---

🦋 ARGUMENTS 🦋

• xe — the xe device instance. that's your girl. that's the whole device you're handing over 🎀

---

✨ DESCRIPTION ✨

okay so real talk: this component? it's responsible for System and Device sleep states. sleep states!! the nap architecture!! 😴✨ it's giving very much "who's allowed to snooze and when" energy, and honestly? obsessed.

and the return situation, because you know we're checking:

• returns 0 for success — yay, ate, no notes 💖
• returns a negative error code otherwise — so if it's not 0, something's up and it's telling you in negative-number form 😭

lowkey a vibe check in integer form: 0 means we're good, anything negative means nope. don't ignore the negative ones, bestie, fr fr.
