Given that the main kernel has had this set for over a year, I'm going to call it good. Setting verification-done-focal for linux-kvm until proven otherwise. I don't see any interested parties in this bug that could perform verification anyway. Its been 3 years since the last non- Canonical comment. ** Tags removed: verification-needed-focal ** Tags added: verification-done-focal -- 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

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

It does, but not working in 100% of cases, for instance when occupied by USB devices that are actively used by certain applications it was failing for me occasionally. The only proper and clean solution is to be able to force the device to use vfio-pci, which is impossible with the kernel Ubuntu ships right now, hence this request to change kernel configuration. -- 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

[Bug 1770845] Re: Make vfio-pci built-in or xhci_hcd optional
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
