Per my Tests we already know that on DD2.0 HW things are fine, you can't enable CCF which is expected, but it doesn't break formerly working cases there. And I'm not sure if there is DD2.3 HW in the wild already.
Furthermore I was in contact with Leonardo yesterday, he is working with the Authors of the patches to let us know if we can safely release the qemu changes before the kernel OR if we have to unroll them for now until this is fixed in the kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1832622 Title: QEMU - count cache flush Spectre v2 mitigation (CVE) (required for POWER9 DD2.3) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1832622/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
