Ubuntu supports a growing number of ARM servers that have PCIe slots,
so external GPUs can be added. CUDA is supported on those platforms
And I do know there are users interested in CUDA on Ubuntu/arm64.

I'm not experienced with CUDA myself - and don't have a card to test it - but
it would be good to know if we're breaking that use case ahead of time.


That's fair enough. I guess that's back to the original statement about  
"Do we really have to cripple an architecture like
>> this?"
It's not about the arch per se it's more about having offerings that match Gpus attached to that arch. So does it make sense to leave them in place and just know you'll have build failures in some cases?
