perf-inject
PERF-INJECT(1) perf Manual PERF-INJECT(1)
NAME
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.

perf-record(1), perf-report(1), perf-archive(1)
