[ INSTRUCTIONS ]

echo 1 > /proc/sys/kernel/sched_schedstats
echo prandom_u32 >> /sys/kernel/debug/tracing/set_event
echo traceon > /sys/kernel/debug/tracing/events/random/prandom_u32/trigger
echo 1 > /sys/kernel/debug/tracing/events/enable

/home/dileks/bin/perf record -e random:prandom_u32 -a -g -- sleep 10

That gives me now some perf data.
