Hmm. I note in this relevant-looking qemu commit: https://github.com/qemu/qemu/commit/2782ad4c4102d57f7f8e135dce0c1adb0149de77 "By now machine firmware should have been upgraded to allow these settings." I wonder if perhaps the firmware on this machine...hasn't? Indeed, running with `-M pseries-3.1` works, which supports my theory. *** Bug 1769445 has been marked as a duplicate of this bug. *** Note this is somewhat similar to, but I think not the *same* as, https://bugzilla.redhat.com/show_bug.cgi?id=1769600 . This case is on power8, and qemu *exits* almost immediately on launch with the error message. That case is on power9, and qemu runs, but cannot successfully boot much past the bootloader. Also, this bug can only be worked around with the pseries-3.1 or lower machine type: trying with `-M pseries-4.0` still produces the error. On the other hand, bug#1769600 can be worked around with pseries-4.0. (In reply to Adam Williamson from comment #1) > Hmm.

So you could restore previous behavior with: ... -M pseries,cap-cfpc=broken,cap-sbbc=broken,cap-ibs=broken ... What is you firmware version: sudo update_flash -d ? Sam, do you know which firmware version we need to support cap-cfpc=workaround,cap-sbbc=workaround,cap-ibs=workaround? Oh, sorry, thought that info was here already but it wasn't (I mentioned it in one of the dupes). It is old indeed: [root@openqa-ppc64le-01 adamwill][PROD]# lsmcode Version of System Firmware : Product Name : OpenPOWER Firmware Product Version : IBM-habanero-ibm-OP8_v1.7_1.62 Product Extra : hostboot-bc98d0b-1a29dff Product Extra : occ-0362706-16fdfa7 Product Extra : skiboot-5.1.13 Product Extra : hostboot-binaries-43d5a59 Product Extra : habanero-xml-a71550e-cdd3b31 Product Extra : capp-ucode-105cb8f I filed an infra issue to get the firmware updated, but doing that seems to require a PhD in ppc64-ology :) https://pagure.io/fedora-infrastructure/issue/8365 I verified on my local Habanero machine that after firmware upgrade to 8348_820.1923.20190613n, I do not have anymore qemu-4.1 failure with default pseries model.

Any chance you can help us upgrade ours, now? (In reply to Adam Williamson from comment #9) > Thanks! Any chance you can help us upgrade ours, now? I will add comments in the related infra issue. (In reply to Laurent Vivier from comment #6) > Sam, > > do you know which firmware version we need to support > cap-cfpc=workaround,cap-sbbc=workaround,cap-ibs=workaround? I'm sorry but I don't. Do you still need to know where support begins, or can you continue using the version that Michel Normand posted above? (I can probably find out, but it's not a trivial task for me.) This message is a reminder that Fedora 31 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 31 on 2020-11-24. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '31'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 31 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. We got the firmwares on the affected boxes updated, I believe, and now we don't really use them any more. Don't think there's anything else to be done here. |
