This command displays the performance counter profile information recorded via perf record.
−i, −−input=
Input file name. (default: perf.data)
−d, −−dsos=

−t, −−field−separator=
Use a special separator character and don’t pad with spaces, replacing all occurances of this separator in symbol names (and other output) 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.
Default: fractal,0.5.
