via perf record.

OPTIONS
-------
-i::
--input=::
        Input file name. (default: perf.data)
-d::
--dsos=::
	Only consider symbols in these dsos. CSV that understands
	file://filename entries.
-n::
--show-nr-samples::
	Show the number of samples for each symbol
-T::
--threads::
	Show per-thread event counters
-C::
--comms=::

	with a '.' character, that thus it's the only non valid separator.

-g [type,min]::
--call-graph::
        Display callchains using type and min percent threshold.
	type can be either:
	- flat: single column, linear exposure of callchains.
	- graph: use a graph tree, displaying absolute overhead rates.
	- fractal: like graph, but displays relative rates. Each branch of
		 the tree is considered as a new profiled object. +
