bcb0b7b1a1c05707304f80ca6f523d557816f85c is the first new commit commit bcb0b7b1a1c05707304f80ca6f523d557816f85c Author: Giuseppe Musacchio <thatle...@gmail.com> Date: Mon Nov 9 10:17:11 2020 +0100 ppc/translate: Rewrite gen_lxvdsx to use gvec primitives Make the implementation match the lxvwsx one. The code is now shorter smaller and potentially faster as the translation will use the host SIMD capabilities if available. No functional change.

And - as always - once you know what you look for it is easier to identify the fix. I think this one is worth a try: commit 861f10fd528263a507476b8c4dda93a9588dfa5c Author: Giuseppe Musacchio <thatle...@gmail.com> Date: Tue May 18 15:30:20 2021 +0200 target/ppc: Fix load endianness for lxvwsx/lxvdsx TARGET_WORDS_BIGENDIAN may not match the machine endianness if that's a runtime-configurable parameter.

The Qemu 6.0 upload https://launchpad.net/ubuntu/+source/qemu/1:6.0+dfsg-1~ubuntu2 triggers a test failure like https://autopkgtest.ubuntu.com/results/autopkgtest-impish/impish/ppc64el/s/systemd/20210708_223311_e3bbb@/log.gz I have tested the new qemu on ppc64 and it worked fine for device emulation and migration cases. But this is suspicious. Of the last tests exactly and only those with the new qemu failed. impish ppc64el tests-in-lxd (F 5% f 0% S 0% B 0% => P 95%/) F.........F............................. systemd-fsckd (F 0% f 0% S 100% B 0% => P 0%/) SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS upstream-1 (F 15% f 0% S 0% B 0% => P 85%/) F..FFFF....F............................ upstream-2 (F 12% f 0% S 0% B 0% => P 87%/) F..FFFF................................. For an insight in flakyness/reproducibility I've retriggered the missing qemu and the non-qemu cases a few times. If those reproduce all-bad vs all-good again this would further indicate a real issue. Unfortunately the ppc maas seems down right now and canonistack also isn't too nice this week - overall that inhibits the testing a bit :-/ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-systems/+bug/1935617/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
