| 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 |
