'perf report' [-i <file> | --input=file]
This command displays the performance counter profile information recorded
via perf record.
Input file name. (default:
Be more verbose. (show symbol address, etc)
Only consider symbols in these dsos. CSV that understands
file://filename entries.
Show the number of samples for each symbol
Show sample percentage for different cpu modes.
Show per-thread event counters
Only consider symbols in these comms. CSV that understands

all occurrences of this separator in symbol names (and other output)
with a '.' character, that thus it's the only non valid separator.
Dump raw trace in ASCII.
-g [type,min]::
Display call chains using type and min percent threshold.
type can be either:
- flat: single column, linear exposure of call chains.
- 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.
Pretty printing style. key: normal, raw
--stdio:: Use the stdio interface.
--tui:: Use the TUI interface, that is integrated with annotate and allows
zooming into DSOs or threads, among other features. Use of --tui
requires a tty, if one is not present, as when piping to other
commands, the stdio interface is used.
