+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
+
+--buildid-all:
+	Inject build-ids of all DSOs 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
+
+--itrace::
+	Decode Instruction Tracing data, replacing it with synthesized events.
+	Options are:
+
+include::itrace.txt[]
+
+--strip::
+	Use with --itrace to strip out non-synthesized events.
+
+-j::
+--jit::
+	Process jitdump files by injecting the mmap records corresponding to jitted
+	functions. This option also generates the ELF images for each jitted function
+	found in the jitdumps files captured in the input perf.data file. Use this option
+	if you are monitoring environment using JIT runtimes, such as Java, DART or V8.
+
+-f::
+--force::
+	Don't complain, do it.
