13 using the event tracing infrastructure.
15 Not all tracepoints can be traced using the event tracing system;
17 tracing information is saved into the tracing buffer, and how the
18 tracing information should be printed.
26 The events which are available for tracing can be found in the file
27 /sys/kernel/debug/tracing/available_events.
30 to /sys/kernel/debug/tracing/set_event. For example::
32 	# echo sched_wakeup >> /sys/kernel/debug/tracing/set_event
39 	# echo '!sched_wakeup' >> /sys/kernel/debug/tracing/set_event
43 	# echo > /sys/kernel/debug/tracing/set_event
47 	# echo *:* > /sys/kernel/debug/tracing/set_event
56 	# echo 'irq:*' > /sys/kernel/debug/tracing/set_event
