perf-report - Read (created by perf record) and display the profile
'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
file://filename entries.
Only consider these symbols. CSV that understands
file://filename entries.
Only display entries resolved to a symbol.
Sort by key(s): pid, comm, dso, symbol, parent.
regex filter to identify parent, see: '--sort parent'
Only display entries with parent-match.
Force each column width to the provided list, for large terminal
Use a special separator character and don't pad with spaces, replacing
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,order]::
Display call chains using type, min percent threshold and order.
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. +
order can be either:
- callee: callee based call graph.
- caller: inverted caller based call graph.
Default: fractal,0.5,callee.
alias for inverted caller based call graph.
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.
vmlinux pathname
kallsyms pathname
Load module symbols. WARNING: This should only be used with -k and
a LIVE kernel.
Don't complain, do it.
Look for files with symbols relative to this directory.
--cpu:: Only report samples for the list of CPUs provided. Multiple CPUs can
be provided as a comma-separated list with no space: 0,1. Ranges of
CPUs are specified with -: 0-2. Default is to report samples on all
--disassembler-style=:: Set disassembler style for objdump.
Interleave source code with assembly code. Enabled by default,
disable with --no-source.
Show raw instruction encoding of assembly instructions.
--show-total-period:: Show a column with the sum of periods.
Display extended information about the file. This adds
information which may be very large and thus may clutter the display.
It currently includes: cpu and numa topology of the host system.
