What you said is mostly wrong.

The kernel part of the GPU driver is massive. It is well known, maybe you were misguided: for instance the AMD GPU drivers are gigantic compared to the actual kernel.

clang(llvm) is playing cat and mouse with gcc extensions and recent ISO C tantrums which creeps into the kernel:Linus T. does not resist those, he does resist only the linux useland ABI(syscalls) breakers.

It's also well known the driver is massive because there are hundreds of thousands of lines of auto-generated register access code in there. Not because it's inherently very complex.

And again you are wrong. It was debunked not a long time ago, and I think it was here on HN. The AMD drivers, kernel side, are still gigantic even excluding the generated register descriptions. Is this what we call a AI lie?

But where you may be right: it seems nvidia hardware programming interface is much cleaner than AMD one and may require much much less code.
