18OPTIONS
19-------
20-i::
21--input=::
22 Input file name. (default: perf.data)
23-d::
24--dsos=::
25 Only consider symbols in these dsos. CSV that understands
26 file://filename entries.
27-n::
28--show-nr-samples::
29 Show the number of samples for each symbol
30-T::
31--threads::
32 Show per-thread event counters
33-C::
34--comms=::
35 Only consider symbols in these comms. CSV that understands
36 file://filename entries.
37-S::
38--symbols=::
39 Only consider these symbols. CSV that understands
40 file://filename entries.
41
42-s::
43--sort=::
44 Sort by key(s): pid, comm, dso, symbol, parent.
45
46-w::
47--field-width=::
48 Force each column width to the provided list, for large terminal
49 readability.
50
51-t::

55 all occurances of this separator in symbol names (and other output)
56 with a '.' character, that thus it's the only non valid separator.
57
58-g [type,min]::
59--call-graph::
60 Display callchains using type and min percent threshold.
61 type can be either:
62 - flat: single column, linear exposure of callchains.
63 - graph: use a graph tree, displaying absolute overhead rates.
64 - fractal: like graph, but displays relative rates. Each branch of
65 the tree is considered as a new profiled object. +
66 Default: fractal,0.5.
