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

Synopsis

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

Description

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.

Options

-i, --input=

Input file name. (default: perf.data 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)

-D, --dump-raw-trace

Dump raw trace in ASCII.

-k, --vmlinux=<file>

vmlinux pathname.

-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.

--stdio

Use the stdio interface.

--stdio-color

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.

--tui

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.

--gtk

Use the GTK interface.

-C, --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.

--asm-raw

Show raw instruction encoding of assembly instructions.

--source

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

--symfs=<directory>

Look for files with symbols relative to this directory.

-M, --disassembler-style=

Set disassembler style for objdump.

--objdump=<path>

Path to objdump binary.

--skip-missing

Skip symbols that cannot be annotated.

--group

Show event group information together
