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.
63 Load module symbols. WARNING: use only with -k and LIVE kernel.
67 Print matching source lines (may be slow).
71 Don't shorten the displayed pathnames.
73 --stdio:: Use the stdio interface.
75 --stdio2:: Use the stdio2 interface, non-interactive, uses the TUI formatting.
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
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.
89 --gtk:: Use the GTK interface.
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
98 Show raw instruction encoding of assembly instructions.
100 --show-total-period:: Show a column with the sum of periods.
103 Interleave source code with assembly code. Enabled by default,
104 disable with --no-source.
106 --symfs=<directory>::
107 Look for files with symbols relative to this directory.
110 --disassembler-style=:: Set disassembler style for objdump.
113 Path to objdump binary.
117 Remove first N entries from source file path names in executables
118 and add PREFIX. This allows to display source code compiled on systems
119 with different file system layout.
122 Skip symbols that cannot be annotated.
125 Show event group information together
128 Set annotation percent type from following choices:
129 global-period, local-period, global-hits, local-hits
131 The local/global keywords set if the percentage is computed
132 in the scope of the function (local) or the whole data (global).
133 The period/hits keywords set the base the percentage is computed
134 on - the samples period or the number of samples (hits).
