1 | perf-inject(1) |
2 | ============== | |

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. | |
