No offense taken! It's a good question. I also have a tested backport of the necessary changes to zesty's 4.10 kernel, I'm just awaiting upstream acceptance of Vijay's patch before doing a final round of testing and sending a PR to the kernel team. WRT the patches impacting !arm, the only one I see here is kvm-all-Pass-an-error-object-to-kvm_device_access.patch, which impacts the error handling of kvm_device_access(). I'd be happy coordinate appropriate testing on other architectures to mitigate the risk there. -dann -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1710019 Title: support GICv3 ITS save/restore & migration Status in linux package in Ubuntu: Triaged Status in qemu package in Ubuntu: Fix Released Status in linux source package in Xenial: Won't Fix Status in qemu source package in Xenial: Triaged Status in linux source package in Zesty: Triaged Status in qemu source package in Zesty: In Progress Bug description: [Impact] Virtual machines on GICv3-based ARM systems cannot be saved/restored or migrated.
