xe_ggtt_init(9)

✨ xe_ggtt_init(9) ✨

okay so bestie, welcome to the xe_ggtt_init page from the Kernel API Manual 💅 this is the one that does the regular, non-early GGTT setup — yes, there's an early version too (xe_ggtt_init_early(9), we'll get there), but this one is the main-character, non-early glow-up 🎀

---

🌸 NAME 🌸

xe_ggtt_init — Regular non-early GGTT initialization. that's it, that's the vibe ✨ ("GGTT" = Global Graphics Translation Table, iykyk 🦋)

---

🫶 SYNOPSIS 🫶

int xe_ggtt_init (struct xe_ggtt *ggtt );

literally the whole signature, no cap 💖 returns an int, takes one pointer, slays.

---

💜 ARGUMENTS 💜

• ggtt — the xe_ggtt to be initialized. that's the one. the star of the show. hand it over and let it cook 👑

---

⭐ RETURN ⭐

• 0 on success 🎉
• a negative error code on failure 😭 (so like, check it, pls, don't just ignore the return value, that's giving chaos energy 💀)

ngl this is the regular init, so if you're looking for the early one you want xe_ggtt_init_early(9) instead — don't mix them up bestie, that's giving undefined-vibe 💀

and that's the page!! short and sweet, just how we like it 🍓 this gem lives under ./drivers/gpu/drm/xe and it's dated October 2026 — mwah, xoxo, go initialize something pretty 💖✨🎀🦋
