Hmm, apparently /usr/bin/perf is only a wrapper script that runs the "right" version of the perf executable for the current kernel. But the perf executable (typically inside /usr/lib/linux-tools-VERSION) is part of the "linux-tools-VERSION" package.
So if I do: $ sudo apt install linux-tools-4.15.0-47/bionic-proposed and then run /usr/lib/linux-tools-4.15.0-47/perf directly, instead of the wrapper script which will still run the perf version for the LTS kernel, things finally work here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396654 Title: C++ demangling support missing from perf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1396654/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
