------- Comment From [email protected] 2017-09-28 10:22 EDT------- If you have an older QEMU than 2.10 you cannot choose -cpu z14 so it should not matter.
The last update was not precise. While qemu 2.10 is sufficient, so is 2.5. Let me explain: The kernel commit changes the Sigp handling in the kernel. This is only used if the QEMU version is older than 2.3 because since QEMU 2.3 (commit f16d3f58748acff4c23f9149c3261844b4d595d5 s390x/kvm: enable the new SIGP handling in user space) sigp set architecture is handled in QEMU anyway and the kernel part is never executed. So kernel commit b697e435aeee99b7 is really just a fixup if somebody uses an ancient QEMU and not necessary. for 16.04 or later. -- 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/1719297 Title: [17.10 FEAT] KVM: CPU Model z14 Status in Ubuntu on IBM z Systems: Fix Committed Status in linux package in Ubuntu: Fix Committed Status in qemu package in Ubuntu: Fix Released Bug description: Kernel team, could you please consider cherrypicking the below commit into the linux kernel for Artful? commit b697e435aeee99b7f5b2d8f8dbb51f791be99b16 Author: Jason J.
