209 core.proc-map-timeout::
211 Can be overridden by the --proc-map-timeout option on supported

408 This option control the way to calculate overhead of filtered entries -
414 33.33% foo
418 This is an original overhead and we'll filter out the first 'foo'
424 ui.show-headers::
429 call-graph.*::
430 The following controls the handling of call-graphs (obtained via the
431 -g/--call-graph options).
433 call-graph.record-mode::
441 call-graph.dump-size::
442 The size of stack to dump in order to do post-unwinding. Default is 8192 (byte).
443 When using dwarf into record-mode, the default size will be used if omitted.
445 call-graph.print-type::
446 The print-types can be graph (graph absolute), fractal (graph relative),
452 40.00% foo
454 ---foo
456 |--50.00%--bar
459 --50.00%--baz
462 This output is a 'fractal' format. The 'foo' came from 'bar' and 'baz' exactly
464 (meaning that it assumes 100% total overhead of 'foo').
466 The 'graph' uses absolute overhead value of 'foo' as total so each of
471 call-graph.order::
482 call-graph.sort-key::
484 The sort-key option determines a way to compare the callchains.
485 A value of 'sort-key' can be 'function' or 'address'.
488 call-graph.threshold::
492 by value depends on call-graph.print-type.
494 call-graph.print-limit::
503 report.percent-limit::
504 This one is mostly the same as call-graph.threshold but works for
506 percentage will not be printed. Default is '0'. If percent-limit
510 report.queue-size::
512 event queue for ordering events. Default is 0, meaning no limit.
523 per event in the group, ref-cycles and cycles:
525 # group: {ref-cycles,cycles}
528 # Samples: 7K of event 'anon group { ref-cycles, cycles }'
535 0.07% 0.00% noploop ld-2.15.so [.] strcmp
538 report.skip-empty::
540 If it's set true, 'perf report --stat' will not show 0 stats.
549 top.call-graph::
550 This is identical to 'call-graph.record-mode', except it is
553 the command line option -g must be specified.
572 '--slab' nor '--page' option is used. Default is 'slab'.
575 record.build-id::
576 This option can be 'cache', 'no-cache', 'skip' or 'mmap'.
577 'cache' is to post-process data and save/update the binaries into
578 the build-id cache (in ~/.debug). This is the default.
579 But if this option is 'no-cache', it will not update the build-id cache.
580 'skip' skips post-processing and does not update the cache.
581 'mmap' skips post-processing and reads build-ids from MMAP events.
583 record.call-graph::
584 This is identical to 'call-graph.record-mode', except it is
587 the command line option -g must be specified.
611 Possible values are 'delta', 'delta-abs', 'ratio' and
649 strace-like sys_enter+sys_exit lines.
653 Can be used to select the default tracer when neither -G nor
654 -F option is not specified. Possible values are 'function' and
669 in particular -i perfdata file, --cpu, --tid
673 convert.queue-size::
674 Limit the size of ordered_events queue, so we could control
679 stat.big-num::
680 (boolean) Change the default for "--big-num". To make
681 "--no-big-num" the default, set "stat.big-num=false".
683 intel-pt.*::
685 intel-pt.cache-divisor::
687 intel-pt.mispred-all::
691 intel-pt.max-loops::
692 If set and non-zero, the maximum number of unconditional
694 the maximum is exceeded there will be a "Never-ending loop"
707 debug-log-buffer-size::
708 Log size in bytes to output when using the option --itrace=d+e
709 Refer 'itrace' option of linkperf:perf-script[1] or
710 linkperf:perf-report[1]. The default is 16384.
