perf-inject: Filter to augment the events stream with additional information

NAME

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

SYNOPSIS

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
