Title: ubuntu-kvm-unit test failed with emulator test on ppc64le Status in The Ubuntu-power-systems project: In Progress Status in linux package in Ubuntu: Confirmed Status in qemu package in Ubuntu: Fix Released Status in linux source package in Xenial: New Status in qemu source package in Xenial: In Progress Status in linux source package in Artful: New Status in qemu source package in Artful: Fix Released Bug description: [Impact] * on start of qemu-system-ppc64 MSR_SF is not set correctly So it doesn't start 64bit as it should * Todays guests usually work around this and are fine, but it is incorrect and might be an issue down the road. Furthermore this is also a fixup to some verification tests at the same time. [Test Case] * 1. deploy xenial + HWE kernel on a ppc64el box 2. sudo apt-get install qemu-kvm -y 3. git clone --depth=1 https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git 4. cd kvm-unit-tests 5. ./configure --endian=little; make 6. sudo ppc64_cpu --smt=off 7. sudo ./run_tests.sh -v [Regression Potential] * The changes are ppc only and provided by IBM so the potential risk is retained to the owner of the Area. Further the change is very small, so it has a very low amount of being misunderstood. [Other Info] * n/a --- Similar to bug 1723904, bug 1712803. The failed "emulator" test from kvm-unit-test will pass with qemu-2.7.1 built from source. ubuntu@modoc:~/kvm-unit-tests$ sudo /bin/bash -c "TESTNAME=emulator TIMEOUT=90s ACCEL= ./powerpc/run powerpc/emulator.elf -smp 1 > " timeout -k 1s --foreground 90s /usr/bin/qemu-system-ppc64 -nodefaults -machine pseries,accel=kvm -bios powerpc/boot_rom.bin -display none -serial stdio -kernel powerpc/emulator.elf -smp 1 # -initrd /tmp/tmp.BJ2sE7V2Jc FAIL: emulator: 64bit: detected PASS: emulator: invalid: exception PASS: emulator: lswx: alignment PASS: emulator: lswi: alignment SUMMARY: 4 tests, 1 unexpected failures EXIT: STATUS=3 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.10.0-37-generic 4.10.0-37.41~16.04.1 ProcVersionSignature: User Name 4.10.0-37.41~16.04.1-generic 4.10.17 Uname: Linux 4.10.0-37-generic ppc64le ApportVersion: 2.20.1-0ubuntu2.10 Architecture: ppc64el Date: Mon Oct 16 10:10:46 2017 ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcLoadAvg: 0.00 0.00 0.57 1/1457 83356 ProcLocks: 1: POSIX ADVISORY WRITE 1604 00:14:19651 0 EOF 2: POSIX ADVISORY WRITE 2937 00:14:55331 0 EOF 3: FLOCK ADVISORY WRITE 3046 00:14:67623 0 EOF 4: POSIX ADVISORY WRITE 3124 00:14:57398 0 EOF 5: POSIX ADVISORY WRITE 3047 00:14:87068 0 EOF ProcSwaps: Filename Type Size Used Priority /swap.img file 8388544 0 -1 ProcVersion: Linux version 4.10.0-37-generic (buildd@bos01-ppc64el-026) (gcc version 5.4.0 20160609 (User Name/IBM 5.4.0-6ubuntu1~16.04.4) ) #41~16.04.1-User Name SMP Fri Oct 6 22:44:24 UTC 2017 SourcePackage: linux-hwe UpgradeStatus: No upgrade log present (probably fresh install) cpu_cores: Number of cores present = 20 cpu_coreson: Number of cores online = 20 cpu_smt: SMT is off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1723914/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
