Hello IBM, I have built a kernel for tests with the patches mentioned in the previous comment:
perf record: Fix s390 missing module symbol and warning for non-root users perf machine: Read also the end of the kernel perf machine: Update kernel map address and re-order properly perf machine: Set main kernel end address properly perf machine: Don't search for active kernel start in __machine__create_kernel_maps perf machine: Generalize machine__set_kernel_mmap() The packages for s390x can be found at: https://people.canonical.com/~ksouza/lp1828166/bionic/ Could you please test the kernel from the link above if it fixes the problem? Thank you. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1828166 Title: perf top problem on z with Ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-z-systems/+bug/1828166/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
