NAME
       perf-inject - Filter to augment the events stream with additional
       information

SYNOPSIS
       perf inject <options>

DESCRIPTION
       perf-inject reads a perf-record event stream and repipes it to stdout.
       At any point the processing code can inject other events into the event
       stream - in this case build-ids (-b option) are read and injected as
       needed into the event stream.

       Build-ids are just the first user of perf-inject - potentially anything
       that needs userspace processing to augment the events stream with
       additional information could make use of this facility.

OPTIONS
       -b, --build-ids=
	   Inject build-ids into the output stream

       -v, --verbose
	   Be more verbose.

       -i, --input=
	   Input file name. (default: stdin)

       -o, --output=
	   Output file name. (default: stdout)

       -s, --sched-stat
	   Merge sched_stat and sched_switch for getting events where and how
	   long tasks slept. sched_switch contains a callchain where a task
	   slept and sched_stat contains a timeslice how long a task slept.
