Hi Philip, Thank you for your prompt response.
I'm experiencing the same error on Jammy with an `i5-12600K`. I have two systems: one running Jammy with an `i5-12600K` and another on Noble with an `i5-12600`. On both setups, `perf c2c record` produces the same error. Previously, the `i5-12600` box was running on RHEL9, where `perf c2c record` didn't work either—it resulted in a Segmentation Fault rather than an error message. Given that Noble introduced no omit frame pointer by default and in hopes that `perf c2c record` might work, I decided to migrate from RHEL9 to Noble. For now, my workaround is to use an older 4th gen i7-4870HQ system, where `perf c2c record` functions correctly on Noble with exactly the same image installed as in the other boxes. It seems like the issue lies with the `perf c2c record` feature in linux-tools, not specifically with Ubuntu. However, it might be worth reporting this to the kernel developers for a potential fix. I also found these commits that added hybrid support (12th gen and onwards) to perf: https://lwn.net/Articles/852302/ but it seems that c2c might have been overlooked. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2077153 Title: perf c2c record is not working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2077153/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
