TTM(9)

🌸 TTM 🌸

okay so bestie, welcome to TTM — it's a memory manager for accelerator devices that have their own dedicated memory. yes, that kind of accelerator. the GPU kind. very main character energy 💅

The basic idea, and honestly it's giving genius: resources get grouped together into buffer objects of a certain size, and TTM handles the lifetime, the movement, and the CPU mappings of those objects. like a little ✨manager✨ for your buffers — it keeps track of when they're born, when they move around, and how the CPU gets to peek at them 🫶

TODO: add more design background and information here. no fr, that's literally what it says — the docs are lowkey still cooking 🙈 so don't come for me, I'm just the messenger 🎀
