💅 ttm_prime_fd_to_handle — the Kernel API Manual, bestie edition

okay so you're looking at ttm_prime_fd_to_handle(9) and honestly? it's giving "small function, big job." let's get into it 🫶

---

✨ NAME ✨

ttm_prime_fd_to_handle — get a base object handle from a prime fd. that's the whole vibe. no cap. 🎀

---

🌸 SYNOPSIS 🌸

int ttm_prime_fd_to_handle (struct ttm_object_file *tfile , int fd , u32 *handle );

yes the spacing is like that, we don't touch it, it's iconic 💅

---

🦋 ARGUMENTS 🦋

• tfile — a struct ttm_object_file that identifies the caller. it's basically the "who dis" of the operation 👑
• fd — the prime / dmabuf fd. the file descriptor in question, the main character of this whole thing 🌟
• handle — the returned handle. this is what you get back, it's the prize at the end of the quest 🎁

---

💖 DESCRIPTION 💖

so what this function actually does: it returns a handle to an object that previously exported a dma-buf. that's it, that's the whole deal. lowkey simple, highkey useful ✨

⚠️ and here's the important bit, bestie, listen up: we don't handle imports yet, because we simply have no consumers of that implementation. fr fr, nobody's using it, so it's not built. don't come for us 😭
