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::

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.
