NAME

6       perf-inject - Filter to augment the events stream with additional
7       information
8

SYNOPSIS

10       perf inject <options>
11

DESCRIPTION

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

OPTIONS

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.

40       --kallsyms=<file>
