Actually no. It builds and does not have any downsides, but does not resolve the issue. Sorry for that. When I looked at the history of cpu_map and this patch, I did not see that it would require further patches to actually make it work.
So that would leave it at these four patches: Add-pschange-mc-no-bit-in-IA32_ARCH_CAPABILITIES-MSR.patch Request-test-files-update-when-adding-x86-features.patch Add-missing-x86-features-in-0x7-CPUID-leaf.patch Add-missing-x86-features-in-0x80000008-CPUID-leaf.patch Add-missing-AMD-SVM-features.patch Plus the patch adding the EPYC-Rome model. I'll try to get it upstream, but it will take some time. From my side, it's totally fine from my side to go ahead with the update without it. My patch queue for qemu also has 2 more patches, reported as LP#1896751 and LP#1896751 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1887490 Title: Add/Backport EPYC-v3 and EPYC-Rome CPU model To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1887490/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
