Maybe for the desktop, but not overall: Nvidia is heavily pushing supercomputing/machine learning and it can't afford to ignore Linux in this space (since Linux dominates).
If Nvidia were to abandon Linux, they would be gifting AMD a free come-back opportunity.
If for some reason supercomputer builders could no longer use the best GPUs in supercomputers, would they stick with Linux or would they follow the hardware and switch to a ⋆BSD on the compute nodes?
I have no idea what the answer would be, but my guess is it would hinge on 1) AMDs reaction, and the performance hit (if any) of switching to AMD GPUs on Linux and 2) the performance hit (if any) of switching the OS to *BSD
Going with second rate option simply doesnt work when you're spending hundreds of millions per machine on the high end.
I mean do you really think it told really be easier to port a thousand heavily optimized applications/libs CUDA to OpenCL than the handfull of librsties that dont alrady work with BSD from Linux?!
