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)
-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
