+Variables
+~~~~~~~~~
+
+colors.*::
+	The variables for customizing the colors used in the output for the
+	'report', 'top' and 'annotate' in the TUI. They should specify the
+	foreground and background colors, separated by a comma, for example:
+
+		medium = green, lightgray
+
+	If you want to use the color configured for you terminal, just leave it
+	as 'default', for example:
+
+		medium = default, lightgray
+
+	Available colors:
+	red, yellow, green, cyan, gray, black, blue,
+	white, default, magenta, lightgray
+
+	colors.top::
+		'top' means a overhead percentage which is more than 5%.
+		And values of this variable specify percentage colors.
+		Basic key values are foreground-color 'red' and
+		background-color 'default'.
+	colors.medium::
+		'medium' means a overhead percentage which has more than 0.5%.
+		Default values are 'green' and 'default'.
+	colors.normal::
+		'normal' means the rest of overhead percentages
+		except 'top', 'medium', 'selected'.
+		Default values are 'lightgray' and 'default'.
+	colors.selected::
+		This selects the colors for the current entry in a list of entries
+		from sub-commands (top, report, annotate).
+		Default values are 'black' and 'lightgray'.
+	colors.jump_arrows::
+		Colors for jump arrows on assembly code listings
+		such as 'jns', 'jmp', 'jane', etc.
+		Default values are 'blue', 'default'.
+	colors.addr::
+		This selects colors for addresses from 'annotate'.
+		Default values are 'magenta', 'default'.
+	colors.root::
+		Colors for headers in the output of a sub-commands (top, report).
+		Default values are 'white', 'blue'.
+
+tui.*, gtk.*::
+	Subcommands that can be configured here are 'top', 'report' and 'annotate'.
+	These values are booleans, for example:
+
+	[tui]
+		top = true
+
+	will make the TUI be the default for the 'top' subcommand. Those will be
+	available if the required libs were detected at tool build time.
+
+buildid.*::
+	buildid.dir::
+		Each executable and shared library in modern distributions comes with a
+		content based identifier that, if available, will be inserted in a
+		'perf.data' file header to, at analysis time find what is needed to do
+		symbol resolution, code annotation, etc.
+
+		The recording tools also stores a hard link or copy in a per-user
+		directory, $HOME/.debug/, of binaries, shared libraries, /proc/kallsyms
+		and /proc/kcore files to be used at analysis time.
+
+		The buildid.dir variable can be used to either change this directory
+		cache location, or to disable it altogether. If you want to disable it,
+		set buildid.dir to /dev/null. The default is $HOME/.debug
+
+annotate.*::
+	These options work only for TUI.
+	These are in control of addresses, jump function, source code
+	in lines of assembly code from a specific program.
+
+	annotate.hide_src_code::
+		If a program which is analyzed has source code,
+		this option lets 'annotate' print a list of assembly code with the source code.
+		For example, let's see a part of a program. There're four lines.
+		If this option is 'true', they can be printed
+		without source code from a program as below.
+
+		│        push   %rbp
+		│        mov    %rsp,%rbp
+		│        sub    $0x10,%rsp
+		│        mov    (%rdi),%rdx
+
+		But if this option is 'false', source code of the part
+		can be also printed as below. Default is 'false'.
+
+		│      struct rb_node *rb_next(const struct rb_node *node)
+		│      {
+		│        push   %rbp
+		│        mov    %rsp,%rbp
+		│        sub    $0x10,%rsp

+		│        mov    (%rdi),%rdx
+		│              return n;
+
+        annotate.use_offset::
+		Basing on a first address of a loaded function, offset can be used.
+		Instead of using original addresses of assembly code,
+		addresses subtracted from a base address can be printed.
+		Let's illustrate an example.
+		If a base address is 0XFFFFFFFF81624d50 as below,
+
+		ffffffff81624d50 <load0>
+
+		an address on assembly code has a specific absolute address as below
+
+		ffffffff816250b8:│  mov    0x8(%r14),%rdi
+
+		but if use_offset is 'true', an address subtracted from a base address is printed.
+		Default is true. This option is only applied to TUI.
+
+		             368:│  mov    0x8(%r14),%rdi
+
+	annotate.jump_arrows::
+		There can be jump instruction among assembly code.
+		Depending on a boolean value of jump_arrows,
+		arrows can be printed or not which represent
+		where do the instruction jump into as below.

+
+		│1382:   movb   $0x1,-0x270(%rbp)
+
+		If use this, the number of branches jumping to that address can be printed as below.
+		Default is 'false'.
+

+
+        annotate.show_total_period::
+		To compare two records on an instruction base, with this option
+		provided, display total number of samples that belong to a line
+		in assembly code. If this option is 'true', total periods are printed
+		instead of percent values as below.
+

+
+hist.*::
+	hist.percentage::
+		This option control the way to calculate overhead of filtered entries -
+		that means the value of this option is effective only if there's a
+		filter (by comm, dso or symbol name). Suppose a following example:
+
+		       Overhead  Symbols
+		       ........  .......
+		        33.33%     foo
+		        33.33%     bar
+		        33.33%     baz
+
+	       This is an original overhead and we'll filter out the first 'foo'
+	       entry. The value of 'relative' would increase the overhead of 'bar'
+	       and 'baz' to 50.00% for each, while 'absolute' would show their
+	       current overhead (33.33%).
+
+ui.*::
+	ui.show-headers::
+		This option controls display of column headers (like 'Overhead' and 'Symbol')
+		in 'report' and 'top'. If this option is false, they are hidden.
+		This option is only applied to TUI.
+
+call-graph.*::
+	When sub-commands 'top' and 'report' work with -g/—-children
+	there're options in control of call-graph.
+
+	call-graph.record-mode::
+		The record-mode can be 'fp' (frame pointer), 'dwarf' and 'lbr'.
+		The value of 'dwarf' is effective only if perf detect needed library
+		(libunwind or a recent version of libdw).
+		'lbr' only work for cpus that support it.
+
+	call-graph.dump-size::
+		The size of stack to dump in order to do post-unwinding. Default is 8192 (byte).
+		When using dwarf into record-mode, the default size will be used if omitted.
+
+	call-graph.print-type::
+		The print-types can be graph (graph absolute), fractal (graph relative),
+		flat and folded. This option controls a way to show overhead for each callchain
+		entry. Suppose a following example.
+
+                Overhead  Symbols
+                ........  .......
+                  40.00%  foo
+                          |
+                          ---foo
+                             |
+                             |--50.00%--bar
+                             |          main
+                             |
+                              --50.00%--baz
+                                        main
+
+		This output is a 'fractal' format. The 'foo' came from 'bar' and 'baz' exactly
+		half and half so 'fractal' shows 50.00% for each
+		(meaning that it assumes 100% total overhead of 'foo').
+
+		The 'graph' uses absolute overhead value of 'foo' as total so each of
+		'bar' and 'baz' callchain will have 20.00% of overhead.
+		If 'flat' is used, single column and linear exposure of call chains.
+		'folded' mean call chains are displayed in a line, separated by semicolons.
+
+	call-graph.order::
+		This option controls print order of callchains. The default is
+		'callee' which means callee is printed at top and then followed by its
+		caller and so on. The 'caller' prints it in reverse order.
+
+		If this option is not set and report.children or top.children is
+		set to true (or the equivalent command line option is given),
+		the default value of this option is changed to 'caller' for the
+		execution of 'perf report' or 'perf top'. Other commands will
+		still default to 'callee'.
+
+	call-graph.sort-key::
+		The callchains are merged if they contain same information.
+		The sort-key option determines a way to compare the callchains.
+		A value of 'sort-key' can be 'function' or 'address'.
+		The default is 'function'.
+
+	call-graph.threshold::
+		When there're many callchains it'd print tons of lines. So perf omits
+		small callchains under a certain overhead (threshold) and this option
+		control the threshold. Default is 0.5 (%). The overhead is calculated
+		by value depends on call-graph.print-type.
+
+	call-graph.print-limit::
+		This is a maximum number of lines of callchain printed for a single
+		histogram entry. Default is 0 which means no limitation.
+
+report.*::
+	report.percent-limit::
+		This one is mostly the same as call-graph.threshold but works for
+		histogram entries. Entries having an overhead lower than this
+		percentage will not be printed. Default is '0'. If percent-limit
+		is '10', only entries which have more than 10% of overhead will be
+		printed.
+
+	report.queue-size::
+		This option sets up the maximum allocation size of the internal
+		event queue for ordering events. Default is 0, meaning no limit.
+
+	report.children::
+		'Children' means functions called from another function.
+		If this option is true, 'perf report' cumulates callchains of children
+		and show (accumulated) total overhead as well as 'Self' overhead.
+		Please refer to the 'perf report' manual. The default is 'true'.
+
+	report.group::
+		This option is to show event group information together.
+		Example output with this turned on, notice that there is one column
+		per event in the group, ref-cycles and cycles:
+
+		# group: {ref-cycles,cycles}
+		# ========
+		#
+		# Samples: 7K of event 'anon group { ref-cycles, cycles }'
+		# Event count (approx.): 6876107743
+		#
+		#         Overhead  Command      Shared Object               Symbol
+		# ................  .......  .................  ...................
+		#
+		    99.84%  99.76%  noploop  noploop            [.] main
+		     0.07%   0.00%  noploop  ld-2.15.so         [.] strcmp
+		     0.03%   0.00%  noploop  [kernel.kallsyms]  [k] timerqueue_del
+
+top.*::
+	top.children::
+		Same as 'report.children'. So if it is enabled, the output of 'top'
+		command will have 'Children' overhead column as well as 'Self' overhead
+		column by default.
+		The default is 'true'.
+
+man.*::
+	man.viewer::
+		This option can assign a tool to view manual pages when 'help'
+		subcommand was invoked. Supported tools are 'man', 'woman'
+		(with emacs client) and 'konqueror'. Default is 'man'.
+
+		New man viewer tool can be also added using 'man.<tool>.cmd'
+		or use different path using 'man.<tool>.path' config option.
+
+pager.*::
+	pager.<subcommand>::
+		When the subcommand is run on stdio, determine whether it uses
+		pager or not based on this value. Default is 'unspecified'.
+
+kmem.*::
+	kmem.default::
+		This option decides which allocator is to be analyzed if neither
+		'--slab' nor '--page' option is used. Default is 'slab'.
+
+record.*::
+	record.build-id::
+		This option can be 'cache', 'no-cache' or 'skip'.
+		'cache' is to post-process data and save/update the binaries into
+		the build-id cache (in ~/.debug). This is the default.
+		But if this option is 'no-cache', it will not update the build-id cache.
+		'skip' skips post-processing and does not update the cache.
