> One interesting question I think is outstanding - from parsing the video carefully, it seems to me that devs are going to want ARM linux virtualized, vs AMD64.
Hahaha, look for a user-agent at 1:44:26 :) They use old Intel Mac for a virtualization demo.
There was a video on YouTube (in russian) where lead developer from MCST confess that they were unable to use this technology in practice. The entire software stack should be ported to strictly eliminate any usage of pointer magic in every place. They poured years on this and only succeed on porting libc and few small base libraries.
Afaik 10 years ago nvidia drivers were most stable and performant on linux. But yes they are proprietary and implemented in userspace for Xorg.
Today Linux graphics stack architecture have been significantly revamped and it requires more kernel code than before for DRM/DRI API and Wayland. nVidia just can't fit into this architecture with its proprietary/nda model without violating GPL for kernel modules.
