Btw, I'm wondering if, alternatively, we add this to the manpage of perf stat and be done with it:
"Remember to turn off HW watchdog temporarily as it is taking up one hw
counter:
$ echo 0 > /proc/sys/kernel/nmi_watchdog
... perf workload
$ echo 1 > /proc/sys/kernel/nmi_watchdog
in case some of the specified events don't get counted."
This solves the problem rather simply :-)))
