✨ xe_svm_init(9) ✨

okay so like, welcome to the Kernel API Manual bestie 💖 this is the xe_svm_init(9) page and honestly it's a short one but it's lowkey a main character moment for your VM, so let's go 🫶

---

🌸 NAME 🌸

xe_svm_init — SVM initialize ✨ (yes that's the whole name, she's concise and we respect it 💅)

---

🦋 SYNOPSIS 🦋

int xe_svm_init (struct xe_vm *vm );

like, she takes one thing and gives you back an int, periodt.

---

🎀 ARGUMENTS 🎀

• vm — The VM. that's it, that's the argument 🫶 she wants the VM and nothing else.

---

💜 DESCRIPTION 💜

So what she does is she initializes the SVM state — and here's the cute part: that state is embedded within the VM itself 🧚 no cap, it lives inside vm, she just wakes it up and gets it ready. it's giving "setting up the vibes before the party starts" 🌈

---

⭐ RETURN ⭐

• 0 on success 🎉
• a negative error code on error 😭 (so like, vibe check the return value, fr fr — anything negative means something went sideways)

ok that's the whole page bestie, short and slay 💅 remember: 0 good, negative bad, and the SVM state is embedded in the VM, iykyk 🦋

and like, a lil sign-off 🎀 this one came out of ./drivers/gpu/drm/xe and it's dated October 2026 — she's from the future, iconic 👑✨
