Could you build this?
No Writing a custom C userspace NVIDIA driver and CUDA runtime/cublas shims over Thunderbolt for Apple Silicon requires elite low-level reverse engineering, hardware architecture expertise, and GPU driver development.
What it would actually take: Requires deep reverse-engineering of NVIDIA's proprietary GPU command submission protocols, memory mapping, PCIe/Thunderbolt BAR management, and undocumented microarchitectural interfaces (e.g. Blackwell/Ada). The stack involves writing custom kernel/userspace drivers in C/C++ (libtinynv) interacting via macOS IOKit/PCIDriverKit, alongside reimplementing subsets of CUDA runtime (cudart) and BLAS interfaces. This demands specialized systems programming expertise in OS kernels, GPU hardware registers, and binary reverse engineering.
