PERF-ANNOTATE(1)                 perf Manual                PERF-ANNOTATE(1)

NAME         top

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

SYNOPSIS         top

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

DESCRIPTION         top

       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         top

       -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)

       -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.

       -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.

       --show-total-period
           Show a column with the sum of periods.

       --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
