perf-annotate(1)
================

NAME
----
perf-annotate - Read perf.data (created by perf record) and display annotated code

SYNOPSIS
--------
[verse]
'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)

-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.

--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

<div class='commit-subject'>Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace</div><div class='commit-msg'>Pull namespace fix from Eric Biederman:
 "This has a single brown bag fix.

  The possible deadlock with dec_pid_namespaces that I had thought was
  fixed earlier turned out only to have been moved. So instead of being
  cleaver this change takes ucounts_lock with irqs disabled. So
  dec_ucount can be used from any context without fear of deadlock.

  The items accounted for dec_ucount and inc_ucount are all
  comparatively heavy weight objects so I don't exepct this will have
  any measurable performance impact"
