Not sure but with the Turing series they support having a cryptographically signed binary blob that they load on the GPU. So before where their kernel driver was a thin shim for the user space driver, now it’s a thin shim for the black box firmware loaded on the GPU
the scope of what the kernel interface provides didn't change, but what was previously a blob wrapped by source-provided "os interface layer" is now moved to run on GSP (RISC-V based) inside the GPU.
