8config INPUT
9	tristate "Generic input layer (needed for keyboard, mouse, ...)" if EXPERT
10	default y
11	help
12	  Say Y here if you have any input device (mouse, keyboard, tablet,
13	  joystick, steering wheel ...) connected to your system and want
14	  it to be available to applications. This includes standard PS/2
15	  keyboard and mouse.
16
17	  Say N here if you have a headless (no monitor, no keyboard) system.
18
19	  More information is available: <file:Documentation/input/input.rst>
20
21	  If unsure, say Y.
22
23	  To compile this driver as a module, choose M here: the
24	  module will be called input.

29	tristate "Export input device LEDs in sysfs"
30	depends on LEDS_CLASS
31	default INPUT
32	help
33	  Say Y here if you would like to export LEDs on input devices
34	  as standard LED class devices in sysfs.
35
36	  If unsure, say Y.
37
38	  To compile this driver as a module, choose M here: the
39	  module will be called input-leds.

41config INPUT_FF_MEMLESS
42	tristate "Support for memoryless force-feedback devices"
43	help
44	  Say Y here if you have memoryless force-feedback input device
45	  such as Logitech WingMan Force 3D, ThrustMaster FireStorm Dual
46	  Power 2, or similar. You will also need to enable hardware-specific
47	  driver.
48
49	  If unsure, say N.
50
51	  To compile this driver as a module, choose M here: the
52	  module will be called ff-memless.
53
54config INPUT_POLLDEV
55	tristate "Polled input device skeleton"
56	help
57	  Say Y here if you are using a driver for an input
58	  device that periodically polls hardware state. This
59	  option is only useful for out-of-tree drivers since
60	  in-tree drivers select it automatically.
61
62	  If unsure, say N.
63
64	  To compile this driver as a module, choose M here: the
65	  module will be called input-polldev.
66
67config INPUT_SPARSEKMAP
68	tristate "Sparse keymap support library"
69	help
70	  Say Y here if you are using a driver for an input
71	  device that uses sparse keymap. This option is only
72	  useful for out-of-tree drivers since in-tree drivers
73	  select it automatically.
74
75	  If unsure, say N.
76
77	  To compile this driver as a module, choose M here: the
78	  module will be called sparse-keymap.
79
80config INPUT_MATRIXKMAP
81	tristate "Matrix keymap support library"
82	help
83	  Say Y here if you are using a driver for an input
84	  device that uses matrix keymap. This option is only
85	  useful for out-of-tree drivers since in-tree drivers
86	  select it automatically.
87
88	  If unsure, say N.
89
90	  To compile this driver as a module, choose M here: the
91	  module will be called matrix-keymap.

95config INPUT_MOUSEDEV
96	tristate "Mouse interface"
97	help
98	  Say Y here if you want your mouse to be accessible as char devices
99	  13:32+ - /dev/input/mouseX and 13:63 - /dev/input/mice as an
100	  emulated IntelliMouse Explorer PS/2 mouse. That way, all user space
101	  programs (including SVGAlib, GPM and X) will be able to use your
102	  mouse.
103
104	  If unsure, say Y.
105
106	  To compile this driver as a module, choose M here: the
107	  module will be called mousedev.
108
109config INPUT_MOUSEDEV_PSAUX
110	bool "Provide legacy /dev/psaux device"
111	depends on INPUT_MOUSEDEV
112	help
113	  Say Y here if you want your mouse also be accessible as char device
114	  10:1 - /dev/psaux. The data available through /dev/psaux is exactly
115	  the same as the data from /dev/input/mice.
116
117	  If unsure, say Y.
118
119config INPUT_MOUSEDEV_SCREEN_X
120	int "Horizontal screen resolution"
121	depends on INPUT_MOUSEDEV
122	default "1024"
123	help
124	  If you're using a digitizer, or a graphic tablet, and want to use
125	  it as a mouse then the mousedev driver needs to know the X window
126	  screen resolution you are using to correctly scale the data. If
127	  you're not using a digitizer, this value is ignored.
128
129config INPUT_MOUSEDEV_SCREEN_Y
130	int "Vertical screen resolution"
131	depends on INPUT_MOUSEDEV
132	default "768"
133	help
134	  If you're using a digitizer, or a graphic tablet, and want to use
135	  it as a mouse then the mousedev driver needs to know the X window
136	  screen resolution you are using to correctly scale the data. If
137	  you're not using a digitizer, this value is ignored.
138
139config INPUT_JOYDEV
140	tristate "Joystick interface"
141	help
142	  Say Y here if you want your joystick or gamepad to be
143	  accessible as char device 13:0+ - /dev/input/jsX device.
144
145	  If unsure, say Y.
146
147	  More information is available: <file:Documentation/input/joydev/joystick.rst>
148
149	  To compile this driver as a module, choose M here: the
150	  module will be called joydev.
151
152config INPUT_EVDEV
153	tristate "Event interface"
154	help
155	  Say Y here if you want your input device events be accessible
156	  under char device 13:64+ - /dev/input/eventX in a generic way.
157
158	  To compile this driver as a module, choose M here: the
159	  module will be called evdev.
160
161config INPUT_EVBUG
162	tristate "Event debugging"
163	help
164	  Say Y here if you have a problem with the input subsystem and
165	  want all events (keypresses, mouse movements), to be output to
166	  the system log. While this is useful for debugging, it's also
167	  a security threat - your keypresses include your passwords, of
168	  course.
169
170	  If unsure, say N.
171
172	  To compile this driver as a module, choose M here: the
173	  module will be called evbug.
174
175config INPUT_APMPOWER
176	tristate "Input Power Event -> APM Bridge" if EXPERT
177	depends on INPUT && APM_EMULATION
178	help
179	  Say Y here if you want suspend key events to trigger a user
180	  requested suspend through APM. This is useful on embedded
181	  systems where such behaviour is desired without userspace
182	  interaction. If unsure, say N.
183
184	  To compile this driver as a module, choose M here: the
185	  module will be called apm-power.
