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.
–kallsyms=<file>
- kallsyms pathname
