It's AMD that has the issue, but that's addressed with 'masked events'. What type of testing would you like to see for filtering or the PMU in general as a selftest? Currently, the test uses architectural events, but with this series we are really only testing 2 of them. There is plenty of room for more / better testing with just architectural events alone. I also add more testing and more variety of counters with masked events. I'm curious where you would like to see additional testing and what real world testing you'd like to see added. > > > KVM: selftests: Test the PMU event "Instructions retired" > > And, do you have further plans to cover more pmu testcases via selftests ? I don't have immediate plans beyond the 2 mentioned above, but I'm always open to more / better testing.
