What is the security status of GPU pass-through? It would be amazing if GPU pass-through could be a fully security-supported feature, although I understand it might not be practical. Most uses for GPU pass-through are for games, which are not trusted at all. If the security risks of (secondary) GPU pass-through could be eliminated, it would be possible to have an “Allow this VM to use hardware-accelerated graphics” checkbox in the GUI, which would be awesome. Obviously, I am only referring to GPUs that do *not* have control over the monitor. Sincerely, Demi -- You received this message because you are subscribed to the Google Groups "qubes-devel" group.
