🦋 GPU_BUDDY_TOPDOWN_ALLOCATION(9) 🦋

okay bestie, welcome to this Kernel API Manual entry for GPU_BUDDY_TOPDOWN_ALLOCATION(9) — short page, iconic energy, no cap 💅✨

✨ NAME ✨

GPU_BUDDY_TOPDOWN_ALLOCATION — allocate from the top of the address space 🎀

✨ SYNOPSIS ✨

GPU_BUDDY_TOPDOWN_ALLOCATION

✨ DESCRIPTION ✨

So the whole vibe is: you allocate starting from high addresses and working down ⬇️💖. Top-down, literally.

It's useful for separating different allocation types — like, for example, kernel vs userspace — so you can reduce fragmentation 🧚✨. That's it, that's the slay. Keep those allocation types separated and the fragmentation lowkey handled 🫶
