perf-annotate — Read (created by perf record) and display annotated code


perf annotate [-i <file> | --input=file] [symbol_name]


This command reads the input file and displays an annotated version of the code. If the object file has debug symbols then the source code will be displayed alongside assembly code.

If there is no debug info in the object, then annotated assembly is displayed.


-i, --input=<file>

Input file name. (default: unless stdin is a fifo)

-d, --dsos=<dso[,dso...]>

Only consider symbols in these dsos.

-s, --symbol=<symbol>

Symbol to annotate.

-f, --force

Don’t do ownership validation.

-v, --verbose

Be more verbose. (Show symbol address, etc)

-q, --quiet

Do not show any message. (Suppress -v)

-n, --show-nr-samples

Show the number of samples for each symbol

-D, --dump-raw-trace

Dump raw trace in ASCII.

-k, --vmlinux=<file>

vmlinux pathname.


Ignore vmlinux files.

-m, --modules

Load module symbols. WARNING: use only with -k and LIVE kernel.

-l, --print-line

Print matching source lines (may be slow).

-P, --full-paths

Don’t shorten the displayed pathnames.


Use the stdio interface.


Use the stdio2 interface, non-interactive, uses the TUI formatting.


always, never or auto, allowing configuring color output via the command line, in addition to via "color.ui" .perfconfig. Use --stdio-color always to generate color even when redirecting to a pipe or file. Using just --stdio-color is equivalent to using always.


Use the TUI interface. Use of --tui requires a tty, if one is not present, as when piping to other commands, the stdio interface is used. This interfaces starts by centering on the line with more samples, TAB/UNTAB cycles through the lines with more samples.


Use the GTK interface.

-C, --cpu=<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 CPUs.


Show raw instruction encoding of assembly instructions.


Show a column with the sum of periods.


Interleave source code with assembly code. Enabled by default, disable with --no-source.


Look for files with symbols relative to this directory.

-M, --disassembler-style=

Set disassembler style for objdump.


Path to objdump binary.


Skip symbols that cannot be annotated.


Show event group information together


Set annotation percent type from following choices: global-period, local-period, global-hits, local-hits

The local/global keywords set if the percentage is computed
in the scope of the function (local) or the whole data (global).
The period/hits keywords set the base the percentage is computed
on - the samples period or the number of samples (hits).
