6 perf-annotate - Read perf.data (created by perf record) and display annotated code
11 'perf annotate' [-i <file> | --input=file] [symbol_name]
15 This command reads the input file and displays an annotated version of the
16 code. If the object file has debug symbols then the source code will be
17 displayed alongside assembly code.
19 If there is no debug info in the object, then annotated assembly is displayed.
25 Input file name. (default: perf.data unless stdin is a fifo)
28 --dsos=<dso[,dso...]>::
29 Only consider symbols in these dsos.
36 Don't do ownership validation.
40 Be more verbose. (Show symbol address, etc)
44 Do not show any message. (Suppress -v)
48 Show the number of samples for each symbol
52 Dump raw trace in ASCII.
62 Options for decoding instruction tracing data. The options are:
66 To disable decoding entirely, use --no-itrace.
70 Load module symbols. WARNING: use only with -k and LIVE kernel.
74 Print matching source lines (may be slow).
78 Don't shorten the displayed pathnames.
80 --stdio:: Use the stdio interface.
82 --stdio2:: Use the stdio2 interface, non-interactive, uses the TUI formatting.
84 --stdio-color=<mode>::
85 'always', 'never' or 'auto', allowing configuring color output
86 via the command line, in addition to via "color.ui" .perfconfig.
87 Use '--stdio-color always' to generate color even when redirecting
88 to a pipe or file. Using just '--stdio-color' is equivalent to
91 --tui:: Use the TUI interface. Use of --tui requires a tty, if one is not
92 present, as when piping to other commands, the stdio interface is
93 used. This interfaces starts by centering on the line with more
94 samples, TAB/UNTAB cycles through the lines with more samples.
96 --gtk:: Use the GTK interface.
99 --cpu=<cpu>:: Only report samples for the list of CPUs provided. Multiple CPUs can
100 be provided as a comma-separated list with no space: 0,1. Ranges of
101 CPUs are specified with -: 0-2. Default is to report samples on all
105 Show raw instruction encoding of assembly instructions.
107 --show-total-period:: Show a column with the sum of periods.
110 Interleave source code with assembly code. Enabled by default,
111 disable with --no-source.
113 --symfs=<directory>::
114 Look for files with symbols relative to this directory.
117 --disassembler-style=:: Set disassembler style for objdump.
120 Path to objdump binary.
124 Remove first N entries from source file path names in executables
125 and add PREFIX. This allows to display source code compiled on systems
126 with different file system layout.
129 Skip symbols that cannot be annotated.
132 Show event group information together
135 Demangle symbol names to human readable form. It's enabled by default,
136 disable with --no-demangle.
139 Demangle kernel symbol names to human readable form (for C++ kernels).
142 Set annotation percent type from following choices:
143 global-period, local-period, global-hits, local-hits
145 The local/global keywords set if the percentage is computed
146 in the scope of the function (local) or the whole data (global).
147 The period/hits keywords set the base the percentage is computed
148 on - the samples period or the number of samples (hits).
