27 To enable a particular event, such as 'sched_wakeup', simply echo it
30 # echo sched_wakeup >> /sys/kernel/debug/tracing/set_event
35 To disable an event, echo the event name to the set_event file prefixed
38 # echo '!sched_wakeup' >> /sys/kernel/debug/tracing/set_event
40 To disable all events, echo an empty line to the set_event file:
42 # echo > /sys/kernel/debug/tracing/set_event
44 To enable all events, echo '*:*' or '*:' to the set_event file:
46 # echo *:* > /sys/kernel/debug/tracing/set_event
55 # echo 'irq:*' > /sys/kernel/debug/tracing/set_event
65 # echo 1 > /sys/kernel/debug/tracing/events/sched/sched_wakeup/enable
69 # echo 0 > /sys/kernel/debug/tracing/events/sched/sched_wakeup/enable
73 # echo 1 > /sys/kernel/debug/tracing/events/sched/enable
