[Test Case] * Use qemu/KVM on a z14R1 and check the cpu features. Lacking such a system the real verification relies on IBM who confirmed to do it. * While unable to really use it for a lot of benefit, you can check the definition exists at least with: $ qemu-system-s390x -cpu ? | grep z14 After the fix this gets the two extra lines: s390 z14ZR1-base IBM z14 Model ZR1 GA1 (static, migration-safe) s390 z14ZR1 IBM z14 Model ZR1 GA1 (migration-safe) [Regression Potential] * I know we are encouraged to think about all possible regressions, but here it is hard to find one. A one line change to a set of definitions that are checked against the machine type. I could only think of fake machine types 3907 environments changing (doesn't exist) Well real z14R1 machines will after the change behave differently by detecting the type correctly, but that is just what is requested in this backport. [Other Info] * n/a ---- Feature Description Provide the CPU model for the IBM z14 ZR1 to enable KVM guests to exploit new hardware features on the z14 ZR1 The required patch is commit f0b9be93001e6215dc1195f3d75ad2da8b3b694a (qemu 3.0) s390x/cpumodels: add z14 Model ZR1 Introduce the new z14 Model ZR1 cpu model. Mostly identical to z14, only the cpu type differs (3906 vs. 3907) Business Case Support z14 ZR1 hardware features with KVM guests To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1780773/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~group.of.nepali.translators Post to : group.of.nepali.translators@lists.launchpad.net Unsubscribe : https://launchpad.net/~group.of.nepali.translators More help : https://help.launchpad.net/ListHelp
