amdgpu_object(9)

🎀 amdgpu_object 🎀

okay so bestie, welcome to the amdgpu_object(9) page from the Kernel API Manual — this is where the kernel spills the tea about buffer objects 💅

This whole thing defines the interfaces for operating on an amdgpu_bo buffer object, which is the literal representation of memory used by the driver — think VRAM, system memory, etc. ✨

So the way the pipeline works: the driver hands DRM/GEM APIs to userspace, and then those DRM/GEM APIs use these interfaces to create/destroy/set buffer objects, which then get managed by the kernel TTM memory manager 🫶

And it's not just a userspace thing — these interfaces are ALSO used internally by kernel clients, including gfx, uvd, etc. for kernel managed allocations used by the GPU. fr fr, everybody's using them 😭
