Before I switched to AMD, I was passing an NVidia GPU (GTX 660) into my virtual machine, and I could unbind and rebind it between nouveau and vfio-pci as much as I wanted. No trouble at all. Even while X was running, once DRI3 support came. I switched to AMD expecting the same functionality. Thankfully, not having said functionality isn't the end of the world, but having to reboot my computer every time I want to play a game in Windows right after playing a game in Linux is exactly the kind of pain that I spent a summer setting up the VM to avoid.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
