NAME¶
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)
-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
