Hi Jianhui, Unfortunately,
1. This issue also occurs to mtk-v6.6 (our work-in-progress kernel branch) which is based on Linux 6.6.22. Could you show me the kernel git repo that Ubuntu Noble is using that does not have this issue? 2. After cherry-pick the following commit to mtk-v5.15, the issue is still reproducible. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/perf/arm_pmu.c?id=5c816728651ae425954542fed64d21d40cb75a9f -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060063 Title: PMU counters for Cortex-A78 not working correctly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-mtk/+bug/2060063/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
