10[verse]
11'perf annotate' [-i <file> | --input=file] [symbol_name]
12
13DESCRIPTION
14-----------
15This command reads the input file and displays an annotated version of the
16code. If the object file has debug symbols then the source code will be
17displayed alongside assembly code.
18
19If there is no debug info in the object, then annotated assembly is displayed.

21OPTIONS
22-------
23-i::
24--input=<file>::
25        Input file name. (default: perf.data unless stdin is a fifo)
26
27-d::
28--dsos=<dso[,dso...]>::
29        Only consider symbols in these dsos.
30-s::
31--symbol=<symbol>::
32        Symbol to annotate.
33
34-f::
35--force::
36        Don't do ownership validation.
37
38-v::
39--verbose::
40        Be more verbose. (Show symbol address, etc)
41
42-q::
43--quiet::
44	Do not show any message.  (Suppress -v)
45
46-n::
47--show-nr-samples::
48	Show the number of samples for each symbol
49
50-D::
51--dump-raw-trace::
52        Dump raw trace in ASCII.
53
54-k::
55--vmlinux=<file>::
56        vmlinux pathname.
57
58--ignore-vmlinux::
59	Ignore vmlinux files.
60
61-m::
62--modules::
63        Load module symbols. WARNING: use only with -k and LIVE kernel.
64
65-l::
66--print-line::
67        Print matching source lines (may be slow).
68
69-P::
70--full-paths::
71        Don't shorten the displayed pathnames.
72
73--stdio:: Use the stdio interface.
74
75--stdio2:: Use the stdio2 interface, non-interactive, uses the TUI formatting.
76
77--stdio-color=<mode>::
78	'always', 'never' or 'auto', allowing configuring color output
79	via the command line, in addition to via "color.ui" .perfconfig.
80	Use '--stdio-color always' to generate color even when redirecting
81	to a pipe or file. Using just '--stdio-color' is equivalent to
82	using 'always'.
83
84--tui:: Use the TUI interface. Use of --tui requires a tty, if one is not
85	present, as when piping to other commands, the stdio interface is
86	used. This interfaces starts by centering on the line with more
87	samples, TAB/UNTAB cycles through the lines with more samples.
88
89--gtk:: Use the GTK interface.
90
91-C::
92--cpu=<cpu>:: Only report samples for the list of CPUs provided. Multiple CPUs can
93	be provided as a comma-separated list with no space: 0,1. Ranges of
94	CPUs are specified with -: 0-2. Default is to report samples on all
95	CPUs.
96
97--asm-raw::
98	Show raw instruction encoding of assembly instructions.
99
100--show-total-period:: Show a column with the sum of periods.
101
102--source::
103	Interleave source code with assembly code. Enabled by default,
104	disable with --no-source.
105
106--symfs=<directory>::
107        Look for files with symbols relative to this directory.
108
109-M::
110--disassembler-style=:: Set disassembler style for objdump.
111
112--objdump=<path>::
113        Path to objdump binary.
114
115--skip-missing::
116	Skip symbols that cannot be annotated.
117
118--group::
119	Show event group information together
