radeon_bo_mmap_offset(9)

💖 radeon_bo_mmap_offset(9) 💖

okay bestie, welcome to the Kernel API Manual — yes that's the manual name, we're in the big leagues now ✨ this one's a lil baby page but it's iconic in its own way, let me put you on 🫶

---

✨ NAME ✨

radeon_bo_mmap_offset — returns the mmap offset of a bo, periodt 💅

So like, the whole personality of this function is "hand me the offset you'd use for mmap on this buffer object." That's it, that's the gig 🎀

---

🌸 SYNOPSIS 🌸

u64 radeon_bo_mmap_offset (struct radeon_bo *bo );

look at that signature, so clean, so u64, we love a return type with range 💜 (copy it exactly when you use it, don't go freelancing with the spacing, iykyk)

---

🦋 ARGUMENTS 🦋

• bo — the radeon object we're querying the offset for 👑 this is the main character here, no cap. It's a struct radeon_bo *, and it's literally the thing you want the mmap offset of. that's the whole vibe check.

---

🍓 DESCRIPTION 🍓

Returns the mmap offset of the object. 💫

That's genuinely the entire description, bestie — no plot twists, no hidden lore, no "however" or "note that" 😭 the function hands you back the mmap offset of the object and then it's done. It's giving short-and-sweet main character energy and honestly? obsessed. Not every kernel function needs a whole backstory 🌈

lowkey, since the manpage literally says "Returns mmap offset of the object" and nothing else — that's the full behavioral spec. don't go inventing extra guarantees, bestie, that's not slay 💀
