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