This should only impact the period wrote to a counter.
There is no functional change.

As far as I know, the kvm-unit-tests-qemu.pmu directly manipulates the
counters. It should not be impacted by the perf changes. That's weird.

Is there a list to show which checks are failed?

Thanks,

We found KUT/pmu test cases could cause many false positives, especially on
some new Platforms, like SPR/EMR. We already have a patch series to fix
these false positives, but unfortunately it's still not merged.

Here is the patch series link. Thanks.

Hi Oliver,

What HW platform do you see this error on? If possible, could you please
apply the previously mentioned KUT/pmu patchset and check if the issue can
be fixed? Thanks.

do you have a repo/branch? unfortunately, our bot failed to fetch this
