1 perf-inject(1) 2 ============== 3 4 NAME 5 ---- 6 perf-inject - Filter to augment the events stream with additional information 7 8 SYNOPSIS 9 -------- 10 [verse] 11 'perf inject <options>' 12 13 DESCRIPTION 14 ----------- 15 perf-inject reads a perf-record event stream and repipes it to stdout. At any 16 point the processing code can inject other events into the event stream - in 17 this case build-ids (-b option) are read and injected as needed into the event 18 stream. 19 20 Build-ids are just the first user of perf-inject - potentially anything that 21 needs userspace processing to augment the events stream with additional 22 information could make use of this facility. 23 24 OPTIONS 25 ------- 26 -b:: 27 --build-ids=:: 28 Inject build-ids into the output stream 29 -v:: 30 --verbose:: 31 Be more verbose. 32 -i:: 33 --input=:: 34 Input file name. (default: stdin) 35 -o:: 36 --output=:: 37 Output file name. (default: stdout) 38 -s:: 39 --sched-stat:: 40 Merge sched_stat and sched_switch for getting events where and how long 41 tasks slept. sched_switch contains a callchain where a task slept and 42 sched_stat contains a timeslice how long a task slept. 43 44 SEE ALSO 45 -------- 46 linkperf:perf-record[1], linkperf:perf-report[1], linkperf:perf-archive[1] 47
