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.
60 Load module symbols. WARNING: use only with -k and LIVE kernel.
64 Print matching source lines (may be slow).
68 Don't shorten the displayed pathnames.
70 --stdio:: Use the stdio interface.
73 'always', 'never' or 'auto', allowing configuring color output
74 via the command line, in addition to via "color.ui" .perfconfig.
75 Use '--stdio-color always' to generate color even when redirecting
76 to a pipe or file. Using just '--stdio-color' is equivalent to
79 --tui:: Use the TUI interface. Use of --tui requires a tty, if one is not
80 present, as when piping to other commands, the stdio interface is
81 used. This interfaces starts by centering on the line with more
82 samples, TAB/UNTAB cycles through the lines with more samples.
84 --gtk:: Use the GTK interface.
87 --cpu:: Only report samples for the list of CPUs provided. Multiple CPUs can
88 be provided as a comma-separated list with no space: 0,1. Ranges of
89 CPUs are specified with -: 0-2. Default is to report samples on all
93 Show raw instruction encoding of assembly instructions.
95 --show-total-period:: Show a column with the sum of periods.
98 Interleave source code with assembly code. Enabled by default,
99 disable with --no-source.
101 --symfs=<directory>::
102 Look for files with symbols relative to this directory.
105 --disassembler-style=:: Set disassembler style for objdump.
108 Path to objdump binary.
111 Skip symbols that cannot be annotated.
114 Show event group information together
