Hi Thomas, thx for the verification. Well, this is (kind of) expected for now. The request to validate (in comment #7 above: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1974433/comments/7) was so far for jammy aka Ubuntu 22.04 only. A separate comment will be added once an updated kernel to verify on focal aka 20.04 is available, but that hasn't happened yet - sorry. Nevertheless, I checked the patches - and they are content-wise all the same (focal master-next, jammy master-next, upstream and the two you've attached). And I also checked their status in our git trees: Jammy/22.04 master-next: $ git log --oneline --grep "Export the extended counter set counters" $ 4834ef0731bd s390/cpumf: add new extended counter set for IBM z16 git tag --contains 4834ef0731bd Ubuntu-5.15.0-36.37 Focal/20.04 master-next: $ git log --oneline --grep "Export the extended counter set counters" 1f583d5cba70 s390/cpumf: add new extended counter set for IBM z16 $ git tag --contains 1f583d5cba70 Ubuntu-5.4.0-116.130 And these are the kernels available in jammy-proposed and focal-proposed as of today: $ rmadison --arch=s390x linux-generic | egrep 'jammy-proposed|focal-proposed' linux-generic | 5.4.0.115.119 | focal-proposed | s390x linux-generic | 5.15.0.36.39 | jammy-proposed | s390x (please ignore the right most digit for now) '5.15.0.36' fits to the jammy git look-up, hence is included (and you could verify it) But '5.4.0.115' is one version older than the focal git look-up: 5.4.0-116, hence not included yet (so you weren't able to verify it) So we need to wait a little bit for the next updated focal kernel, and once available in focal-proposed, an additional comment will be added here.

This bug is awaiting verification that the linux/5.15.0-36.37 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Kernel-packages] [Bug 1974433] Re: [UBUNTU 20.04] CPU-MF: add extended counter set definitions for new IBM z16
Hi Thomas, I've noticed that the commit: c9311de71635d3eaa158df8516b9b99a92d60a0c "s390/cpumf: add new extended counter set for IBM z16" already landed in linux-next, and cherry-picked directly from there, which worked on focal, impish and also jammy. This is for us the preferable way in terms of maintenance and traceability.
