xe_ggtt_node_save(9)

✨ xe_ggtt_node_save(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 today's main character is xe_ggtt_node_save(9) — yes that's the header, yes I folded the manual name in right here, we're being efficient today 🎀

---

🌸 NAME 🌸

xe_ggtt_node_save — save a &xe_ggtt_node to a buffer. that's it, that's the whole vibe ✨

---

🦋 SYNOPSIS 🦋

int xe_ggtt_node_save (struct xe_ggtt_node *node , void *dst , size_t
size , u16 vfid );

copy it exactly, don't get cute with the spacing, the compiler does not care about your aesthetic 😭

---

💖 ARGUMENTS 💖

• node — the xe_ggtt_node that's getting saved. she's the subject of the whole operation 👑
• dst — the destination buffer. where the saving actually lands 🎀
• size — the destination buffer size, measured in bytes. ngl, please get this right 🙈
• vfid — the VF identifier. lowkey just an identifier, but she matters 🦋

---

⭐ RETURN ⭐

0 on success, or a negative error code on failure. so like, zero is the slay outcome, anything negative is giving "we don't talk about it" 💀
