1perf-inject(1) 2============== 3 4NAME 5---- 6perf-inject - Filter to augment the events stream with additional information 7 8SYNOPSIS 9-------- 10[verse] 11'perf inject <options>' 12 13DESCRIPTION 14----------- 15perf-inject reads a perf-record event stream and repipes it to stdout. At any 16point the processing code can inject other events into the event stream - in 17this case build-ids (-b option) are read and injected as needed into the event 18stream. 19 20Build-ids are just the first user of perf-inject - potentially anything that 21needs userspace processing to augment the events stream with additional 22information could make use of this facility. 23 24OPTIONS 25------- 26-b:: 27--build-ids=:: 28 Inject build-ids into the output stream 29-v:: 30--verbose:: 31 Be more verbose. 32-i:: 33--input=:: 34 Input file name. (default: stdin) 35-o:: 36--output=:: 37 Output file name. (default: stdout) 38-s:: 39--sched-stat:: 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. 43 44--kallsyms=<file>:: 45 kallsyms pathname 46 47--itrace:: 48 Decode Instruction Tracing data, replacing it with synthesized events. 49 Options are: 50 51include::itrace.txt[] 52 53--strip:: 54 Use with --itrace to strip out non-synthesized events. 55 56-j:: 57--jit:: 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. 62 63-f:: 64--force:: 65 Don't complain, do it. 66 67SEE ALSO 68-------- 69linkperf:perf-record[1], linkperf:perf-report[1], linkperf:perf-archive[1] 70
