- 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.
- --kallsyms=<file>::
- kallsyms pathname
- --itrace::
- Decode Instruction Tracing data, replacing it with synthesized events.
- Options are:
- include::itrace.txt[]
- --strip::
- Use with --itrace to strip out non-synthesized events.
