- Only consider symbols in these dsos. CSV that understands

- Show the number of samples for each symbol
- -T
- --threads
- Show per-thread event counters

- -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. +
