gpu_buddy_a...ddr_to_block(9)

💅 gpu_buddy_a...ddr_to_block(9) — like, the Kernel API Manual page, bestie ✨

okay so picture this: you're deep in the kernel API manual (section 9, the real one), and you've got a relative address and a dream. this page is gpu_buddy_allocated_addr_to_block, and it's literally the function that goes "bestie, which allocated block does this address belong to?" 🎀

✨ NAME ✨

gpu_buddy_allocated_addr_to_block — given a relative address, find the allocated block 🦋

like. that's the whole job. hand it an address, get the block back. no cap.

---

🌸 SYNOPSIS 🌸

struct gpu_buddy_block * gpu_buddy_allocated_addr_to_block (struct gpu_buddy *mm , u64 addr );

that signature is iconic and we're not touching a single character of it 💜

---

🫶 ARGUMENTS 🫶

• mm — the GPU buddy manager. your main character, honestly 👑
• addr — the relative address. yes, relative. that's the vibe check it has to pass 🌈

---

⭐ RETURN ⭐

• a gpu_buddy_block on success 💖
• NULL or an error code on failure 😭

ngl, bestie — always check it. NULL does not text back and neither do error codes. 🙈
