This patch adds two new options to perf annotate: - --no-asm-raw : Do not display raw instruction encodings - --no-source : Do not interleave source code with assembly code We believe those options make the output of annotate more readable. Systematically displaying source can make it hard to follow code and especially optimized code. Raw encodings are not useful in most cases.

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)
|
|
|
|
-d::
|
|
--dsos=<dso[,dso...]>::
|
|
Only consider symbols in these dsos.
|
|
-s::
|
|
--symbol=<symbol>::
|
|
Symbol to annotate.
|
|
|
|
-f::
|
|
--force::
|
|
Don't complain, do it.
|
|
|
|
-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.
|
|
|
|
--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.
|
|
|
|
-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. They
|
|
are displayed by default, disable with --no-asm-raw.
|
|
|
|
--source::
|
|
Interleave source code with assembly code. Enabled by default,
|
|
disable with --no-source.
