Hey! The patchset seems incomplete: 8339cae23d79be97a38df3852ef5dab870806a58 should add speculative control CPUID support for guests but only the AMD part is here. When running a guest on top of KVM, CPUID doesn't contain the spec-ctrl bit.
I am using this patch instead: https://github.com/exoscale/pkg-kernel-4.4/blob/4d0b19ad0379ba20846634e21ec01922222a9326/debian/patches/ibrs%2Bkvm/27-kvm-x86-add-speculative-control-cpuid-support-for-guests.patch It also needs the following patch: https://github.com/exoscale/pkg-kernel-4.4/blob/4d0b19ad0379ba20846634e21ec01922222a9326/debian/patches/ibrs%2Bkvm/32-x86-provide-get-scattered-cpuid-leaf.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1742995 Title: linux: 4.4.0-110.133 -proposed tracker To manage notifications about this bug go to: https://bugs.launchpad.net/kernel-sru-workflow/+bug/1742995/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
