** Description changed: + == Justification == + The cp_abort test in context_switch was designed for Power9, however + this test is broken and it fails everytime as Paste on Power9 only + works on accelerators and no longer on real memory. + + == Fix == + 00c946a0 (selftests/powerpc: Remove redundant cp_abort test) + + This will remove the cp_abort test. + Patch has already been applied in C and onward. + + == Test == + Patch verified on a Bionic P9 system, the test will no longer exist. + + == Regression Potential == + None. + This patchset is just for the kernel testing tool. + + + == Original Bug Report == This issue can only be reproduced on Power9 with Bionic kernel. - $ sudo ./cp_abort + $ sudo ./cp_abort test: cp_abort tags: git_version:c186097-dirty !! killing cp_abort !! child died by signal 15 failure: cp_abort It will get skipped on P8 Also to note that this test was completely removed in Cosmic with commit 00c946a06e ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-image-4.15.0-44-generic 4.15.0-44.47 ProcVersionSignature: Ubuntu 4.15.0-44.47-generic 4.15.18 Uname: Linux 4.15.0-44-generic ppc64le AlsaDevices: - total 0 - crw-rw---- 1 root audio 116, 1 Jan 24 07:22 seq - crw-rw---- 1 root audio 116, 33 Jan 24 07:22 timer + total 0 + crw-rw---- 1 root audio 116, 1 Jan 24 07:22 seq + crw-rw---- 1 root audio 116, 33 Jan 24 07:22 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay': 'aplay' ApportVersion: 2.20.9-0ubuntu7.5 Architecture: ppc64el ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord': 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: Date: Thu Jan 24 09:06:32 2019 IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig': 'iwconfig' Lsusb: - Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub - Bus 001 Device 003: ID 0451:80ff Texas Instruments, Inc. - Bus 001 Device 004: ID 0557:2419 ATEN International Co., Ltd - Bus 001 Device 002: ID 0557:7000 ATEN International Co., Ltd Hub - Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub + Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub + Bus 001 Device 003: ID 0451:80ff Texas Instruments, Inc. + Bus 001 Device 004: ID 0557:2419 ATEN International Co., Ltd + Bus 001 Device 002: ID 0557:7000 ATEN International Co., Ltd Hub + Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub PciMultimedia: - + ProcFB: 0 astdrmfb ProcKernelCmdLine: root=UUID=acd1a0d7-f6fc-4130-928c-c8b11ad6e4be ro console=hvc0 ProcLoadAvg: 0.07 0.03 0.42 1/1360 33961 ProcLocks: - 1: FLOCK ADVISORY WRITE 3482 00:17:520 0 EOF - 2: POSIX ADVISORY WRITE 3746 00:17:580 0 EOF - 3: POSIX ADVISORY WRITE 1800 00:17:368 0 EOF - 4: FLOCK ADVISORY WRITE 3744 00:17:568 0 EOF - 5: POSIX ADVISORY WRITE 3831 00:17:588 0 EOF + 1: FLOCK ADVISORY WRITE 3482 00:17:520 0 EOF + 2: POSIX ADVISORY WRITE 3746 00:17:580 0 EOF + 3: POSIX ADVISORY WRITE 1800 00:17:368 0 EOF + 4: FLOCK ADVISORY WRITE 3744 00:17:568 0 EOF + 5: POSIX ADVISORY WRITE 3831 00:17:588 0 EOF ProcSwaps: - Filename Type Size Used Priority - /swap.img file 8388544 0 -2 + Filename Type Size Used Priority + /swap.img file 8388544 0 -2 ProcVersion: Linux version 4.15.0-44-generic (buildd@bos02-ppc64el-004) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #47-Ubuntu SMP Mon Jan 14 11:26:40 UTC 2019 RelatedPackageVersions: - linux-restricted-modules-4.15.0-44-generic N/A - linux-backports-modules-4.15.0-44-generic N/A - linux-firmware 1.173.3 + linux-restricted-modules-4.15.0-44-generic N/A + linux-backports-modules-4.15.0-44-generic N/A + linux-firmware 1.173.3 RfKill: Error: [Errno 2] No such file or directory: 'rfkill': 'rfkill' SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) VarLogDump_list: total 0 cpu_cores: Number of cores present = 40 cpu_coreson: Number of cores online = 40 cpu_dscr: DSCR is 5 cpu_freq: - min: 2.862 GHz (cpu 159) - max: 2.863 GHz (cpu 1) - avg: 2.862 GHz + min: 2.862 GHz (cpu 159) + max: 2.863 GHz (cpu 1) + avg: 2.862 GHz cpu_runmode: - Could not retrieve current diagnostics mode, - No kernel interface to firmware + Could not retrieve current diagnostics mode, + No kernel interface to firmware cpu_smt: SMT=4
