perf-inject(1) ============== NAME ---- perf-inject - Filter to augment the events stream with additional information SYNOPSIS -------- [verse] 'perf inject ' 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=:: kallsyms pathname SEE ALSO -------- linkperf:perf-record[1], linkperf:perf-report[1], linkperf:perf-archive[1]
