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

-o::
|
|
--output=::
|
|
Output file name. (default: stdout)
|
|
-s::
|
|
--sched-stat::
|
|
Merge sched_stat and sched_switch for getting events where and how long
|

|
sched_stat contains a timeslice how long a task slept.
