This could happen very briefly before they are first preempted. This only affects arm64 CPUs that support virtualization. [Regression potential] This could break virtualization or guest access to PMU registers. [Test case] A guest has been run with a host with the patched kernel. perf top has been run on the guest. Using uvtool: host$ sudo apt install uvtool qemu-efi-aarch64 host$ uvt-kvm create test release=eoan arch=arm64 host$ uvt-kvm ssh test guest$ sudo perf top To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1860657/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
