6 perf-inject - Filter to augment the events stream with additional information
11 'perf inject <options>'
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
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.
28 Inject build-ids into the output stream
34 Input file name. (default: stdin)
37 Output file name. (default: stdout)
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.
48 Decode Instruction Tracing data, replacing it with synthesized events.
54 Use with --itrace to strip out non-synthesized events.
58 Process jitdump files by injecting the mmap records corresponding to jitted
59 functions. This option also generates the ELF images for each jitted function
60 found in the jitdumps files captured in the input perf.data file. Use this option
61 if you are monitoring environment using JIT runtimes, such as Java, DART or V8.
