✨ xe_guc_buf_flush(9) ✨

okay so real talk, bestie, this is a page straight out of the Kernel API Manual and it's literally only one function long, so consider this a lil snack-sized manpage 🍓 it's giving short, sweet, and very much to the point.

---

🌸 NAME 🌸

xe_guc_buf_flush — copies the data from the sub-allocation over to the GPU memory 💅 that's it, that's the whole job, and honestly? she ate. no cap.

---

🦋 SYNOPSIS 🦋

u64 xe_guc_buf_flush (const struct xe_guc_buf buf );

like yes, that's the whole signature. u64 going in as the return type, one const struct xe_guc_buf coming through the door. iconic. 👑

---

🎀 ARGUMENTS 🎀

• buf — the xe_guc_buf you want to flush 🫶 that's the one getting sent off to the GPU memory, so make sure it's the one you actually meant, bestie, iykyk.

---

⭐ RETURN ⭐

returns a GPU address of the sub-allocation ✨ so like, you hand it a buf, and it hands you back the GPU address — a fair trade fr fr. 💜
