6 perf-inject - Filter to augment the events stream with additional information
11 'perf inject <options>'
15 perf-inject reads a perf-record event stream and repipes it to stdout. At any
16 point the processing code can inject other events into the event stream - in
17 this case build-ids (-b option) are read and injected as needed into the event
20 Build-ids are just the first user of perf-inject - potentially anything that
21 needs userspace processing to augment the events stream with additional
22 information could make use of this facility.
28 Inject build-ids into the output stream
34 Input file name. (default: stdin)
37 Output file name. (default: stdout)
40 Merge sched_stat and sched_switch for getting events where and how long
41 tasks slept. sched_switch contains a callchain where a task slept and
42 sched_stat contains a timeslice how long a task slept.
