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.
