perf-inject(1)
==============

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

SYNOPSIS
--------
[verse]
'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.
