Hello Markus, or anyone else affected, Accepted qemu into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/qemu/1:6.2+dfsg-2ubuntu6.25 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-jammy. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: qemu (Ubuntu Jammy) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-jammy -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2019968 Title: Add missing feature bits in EPYC-Milan model Status in linux package in Ubuntu: Confirmed Status in qemu package in Ubuntu: Fix Released Status in linux source package in Jammy: Confirmed Status in qemu source package in Jammy: Fix Committed Status in linux source package in Kinetic: Won't Fix Status in qemu source package in Kinetic: Won't Fix Status in linux source package in Lunar: Won't Fix Status in qemu source package in Lunar: Won't Fix Status in linux source package in Mantic: Won't Fix Status in qemu source package in Mantic: Won't Fix Bug description: [Impact] Add the following feature bits for EPYC-Milan model and bump the version. vaes : Vector VAES(ENC|DEC), VAES(ENC|DEC)LAST instruction support vpclmulqdq : Vector VPCLMULQDQ instruction support stibp-always-on : Single Thread Indirect Branch Prediction Mode has enhanced performance and may be left Always on amd-psfd : Predictive Store Forward Disable no-nested-data-bp : Processor ignores nested data breakpoints lfence-always-serializing : LFENCE instruction is always serializing null-sel-clr-base : Null Selector Clears Base. When this bit is set, a null segment load clears the segment base [Test Plan] * First of all we'll (and have in advance) run general regression tests * Qemu shall show to be aware of the new types # qemu-system-x86_64 -cpu ? | grep EPYC-Milan x86 EPYC-Milan (alias configured by machine type) x86 EPYC-Milan-v1 AMD EPYC-Milan Processor x86 EPYC-Milan-v2 AMD EPYC-Milan Processor [Where problems could occur] * There are two areas to look at a) compat behavior on old systems - e.g. libvirt would now detect IBRS on such AMD chips and one might wonder about the change. E.g. compatibility would exist between old-code/new-code/old->new code; but any action (e.g. suspend resume) from new to old code might run into trouble (not supported that way but worth to mention for awareness) b) Migrations between systems - this should be covered by chip versioning but still is worth to mention. Versioning will recognize a formerly started system as v1 and continue to handle it that way. Only new started guests would become v2 and behave the new and improved way.
