Pffftt, too slow right? Maybe not. those amazing folks at Asahi Linux have solved the Linux problem of having to pass through a GPU to the VM. The GPU stays on the Host, the drivers for the GPU stays on the Host side of the VM, each VM can use the GPU as if it were dedicated to it. The next hurdle will be can I take advantage of multi-session support...if you own an NVIDIA RTX GPU, sorry no dice that single session only, if you own a AMD RX GPU, sorry no dice that's also single session, but what if my CPU where Intel with a Xe GPU....that supports multiple sessions. We have two legs down to our three legged stool (x86/x86_64 code running on ARM, and use of the GPU without losing the ability to use it for the host)...could multi-session be next? </video> <video> The 2030 Computing Barrier: Solving Energy Overload Description: By 2030, the computing community will face an unprecedented crisis: the data we generate will outpace our ability to store and process it efficiently, while the energy demands of traditional computing will become unsustainable.
