I've tested to process the perf man pages with asciidoctor that is picker than asciidoc, and it revealed minor syntax errors in some documents. Namely, the title markers aren't aligned with the previous line, hence asciidoctor didn't recognize as titles. This patch corrects these markers to be processed properly.

NAME
|
|
----
|
|
perf-ftrace - simple wrapper for kernel's ftrace functionality
|
|
|
|
|
|
SYNOPSIS
|
|
--------
|
|
[verse]
|
|
'perf ftrace' <command>
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
The 'perf ftrace' command is a simple wrapper of kernel's ftrace
|
|
functionality. It only supports single thread tracing currently and
|
|
just reads trace_pipe in text and then write it to stdout.
|
|
|
|
The following options apply to perf ftrace.
|
|
|
|
OPTIONS
|
|
-------
|
|
|
|
-t::
|
|
--tracer=::
|
|
Tracer to use: function_graph or function.
|
|
|
|
-v::
|
|
--verbose=::
|
|
Verbosity level.
|
|
|
|
-p::
|
|
--pid=::
|
|
Trace on existing process id (comma separated list).
|
|
|
|
-a::
|
|
--all-cpus::
|
|
Force system-wide collection. Scripts run without a <command>
|
|
normally use -a by default, while scripts run with a <command>
|
|
normally don't - this option allows the latter to be run in
|
|
system-wide mode.
|
|
|
|
-C::
|
|
--cpu=::
|
|
Only trace for the list of CPUs provided. Multiple CPUs can
|
|
be provided as a comma separated list with no space like: 0,1.
|
|
Ranges of CPUs are specified with -: 0-2.
|
|
Default is to trace on all online CPUs.
|
|
|
|
-T::
|
|
--trace-funcs=::
|
|
Only trace functions given by the argument. Multiple functions
|
|
can be given by using this option more than once. The function
|
|
argument also can be a glob pattern. It will be passed to
|
|
'set_ftrace_filter' in tracefs.
|
|
|
|
-N::
|
|
--notrace-funcs=::
|
|
Do not trace functions given by the argument. Like -T option,
|
|
this can be used more than once to specify multiple functions
|
|
(or glob patterns). It will be passed to 'set_ftrace_notrace'
|
|
in tracefs.
|
|
|
|
-G::
|
|
--graph-funcs=::
|
|
Set graph filter on the given function (or a glob pattern).
|
|
This is useful for the function_graph tracer only and enables
|
|
tracing for functions executed from the given function.
|
|
This can be used more than once to specify multiple functions.
|
|
It will be passed to 'set_graph_function' in tracefs.
|
|
|
|
-g::
|
|
--nograph-funcs=::
|
|
Set graph notrace filter on the given function (or a glob pattern).
|
|
Like -G option, this is useful for the function_graph tracer only
|
|
and disables tracing for function executed from the given function.
|
|
This can be used more than once to specify multiple functions.
|
|
It will be passed to 'set_graph_notrace' in tracefs.
|
|
|
|
-D::
|
|
--graph-depth=::
|
|
Set max depth for function graph tracer to follow
|
|
