Including VFIO in the kernel would be great! This would resolve all kinds of pass-through crashes.
Currently, the only way to do this is to hope that the USB controller behaves properly during reclamation by the kernel (most of them do not), which varies wildly by vendor. In my case, it gets as bad as having the whole system hang on shutdown due to a crash in the xhci_hcd driver. The ideal solution would be the ability to pass the device through directly to a VM guest, so that no cooperation by the controller is required. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770845 Title: Make vfio-pci built-in or xhci_hcd optional To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1770845/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
