Public bug reported: QEMU added a separate model for EPYC-Milan in
https://lists.gnu.org/archive/html/qemu-devel/2021-02/msg03370.html On the qemu side most bits are already present as far back as focal. The only things missing are the ibrs and svme-addr-chk flag. On the libvirt side the same and fsrm (which is already in qemu) fsrm https://gitlab.com/libvirt/libvirt/-/commit/8c5c660b99101544d8cfcb8edbe48688c04bee25 svme-addr-chk (later patch fixed spelling) https://gitlab.com/libvirt/libvirt/-/commit/5ac6ab2fde63881d3c5cc7372a0d0e59618feb55 ibrs https://gitlab.com/libvirt/libvirt/-/commit/5c17a7ba41670f3182186c06e621995b5d03fc95 EPYC-Milan model https://gitlab.com/libvirt/libvirt/-/commit/f321a4822e9fa6542e48a78611989ecd9acaa83a https://gitlab.com/libvirt/libvirt/-/commit/d3de79dbfc20dc4dfc19154b16079861c542b71e spelling fix for svme-addr-chk https://gitlab.com/libvirt/libvirt/-/commit/b5abf9a192248b1005f63a7102d2627375d70fe5 Please consider adding/backporting these. Of course there are a number of kernel commits, some/most listed in the qemu commit, that would need to be backported to enable all features. But even without them, this already works for the most part (tested on focal kernel 5.4.0-70). ** Affects: qemu (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1921880 Title: Add EPYC-Milan model To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1921880/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
