I have to wonder how this was tested. I tried this on 4.14.y, but when I
do "perf record -e cycles", I get no samples. Moreover, when I check the
PMU interrupts, "grep pmu /proc/interrupts", it shows 0 interrupts from
the ARM PMU all the time.
Why am I not getting any PMU interrupts when using perf ?
