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.txt>
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.

26if INPUT
27
28config INPUT_FF_MEMLESS
29	tristate "Support for memoryless force-feedback devices"
30	help
31	  Say Y here if you have memoryless force-feedback input device
32	  such as Logitech WingMan Force 3D, ThrustMaster FireStorm Dual
33	  Power 2, or similar. You will also need to enable hardware-specific
34	  driver.
35
36	  If unsure, say N.
37
38	  To compile this driver as a module, choose M here: the
39	  module will be called ff-memless.
40
41config INPUT_POLLDEV
42	tristate "Polled input device skeleton"
43	help
44	  Say Y here if you are using a driver for an input
45	  device that periodically polls hardware state. This
46	  option is only useful for out-of-tree drivers since
47	  in-tree drivers select it automatically.
48
49	  If unsure, say N.
50
51	  To compile this driver as a module, choose M here: the
52	  module will be called input-polldev.
53
54config INPUT_SPARSEKMAP
55	tristate "Sparse keymap support library"
56	help
57	  Say Y here if you are using a driver for an input
58	  device that uses sparse keymap. This option is only
59	  useful for out-of-tree drivers since in-tree drivers
60	  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 sparse-keymap.

69config INPUT_MOUSEDEV
70	tristate "Mouse interface" if EXPERT
71	default y
72	help
73	  Say Y here if you want your mouse to be accessible as char devices
74	  13:32+ - /dev/input/mouseX and 13:63 - /dev/input/mice as an
75	  emulated IntelliMouse Explorer PS/2 mouse. That way, all user space
76	  programs (including SVGAlib, GPM and X) will be able to use your
77	  mouse.
78
79	  If unsure, say Y.
80
81	  To compile this driver as a module, choose M here: the
82	  module will be called mousedev.
83
84config INPUT_MOUSEDEV_PSAUX
85	bool "Provide legacy /dev/psaux device"
86	default y
87	depends on INPUT_MOUSEDEV
88	help
89	  Say Y here if you want your mouse also be accessible as char device
90	  10:1 - /dev/psaux. The data available through /dev/psaux is exactly
91	  the same as the data from /dev/input/mice.
92
93	  If unsure, say Y.
94
95
96config INPUT_MOUSEDEV_SCREEN_X
97	int "Horizontal screen resolution"
98	depends on INPUT_MOUSEDEV
99	default "1024"
100	help
101	  If you're using a digitizer, or a graphic tablet, and want to use
102	  it as a mouse then the mousedev driver needs to know the X window
103	  screen resolution you are using to correctly scale the data. If
104	  you're not using a digitizer, this value is ignored.
105
106config INPUT_MOUSEDEV_SCREEN_Y
107	int "Vertical screen resolution"
108	depends on INPUT_MOUSEDEV
109	default "768"
110	help
111	  If you're using a digitizer, or a graphic tablet, and want to use
112	  it as a mouse then the mousedev driver needs to know the X window
113	  screen resolution you are using to correctly scale the data. If
114	  you're not using a digitizer, this value is ignored.
115
116config INPUT_JOYDEV
117	tristate "Joystick interface"
118	help
119	  Say Y here if you want your joystick or gamepad to be
120	  accessible as char device 13:0+ - /dev/input/jsX device.
121
122	  If unsure, say Y.
123
124	  More information is available: <file:Documentation/input/joystick.txt>
125
126	  To compile this driver as a module, choose M here: the
127	  module will be called joydev.
128
129config INPUT_EVDEV
130	tristate "Event interface"
131	help
132	  Say Y here if you want your input device events be accessible
133	  under char device 13:64+ - /dev/input/eventX in a generic way.
134
135	  To compile this driver as a module, choose M here: the
136	  module will be called evdev.
137
138config INPUT_EVBUG
139	tristate "Event debugging"
140	help
141	  Say Y here if you have a problem with the input subsystem and
142	  want all events (keypresses, mouse movements), to be output to
143	  the system log. While this is useful for debugging, it's also
144	  a security threat - your keypresses include your passwords, of
145	  course.
146
147	  If unsure, say N.
148
149	  To compile this driver as a module, choose M here: the
150	  module will be called evbug.
151
152config INPUT_APMPOWER
153	tristate "Input Power Event -> APM Bridge" if EXPERT
154	depends on INPUT && APM_EMULATION
155	help
156	  Say Y here if you want suspend key events to trigger a user
157	  requested suspend through APM. This is useful on embedded
158	  systems where such behaviour is desired without userspace
159	  interaction. If unsure, say N.
160
161	  To compile this driver as a module, choose M here: the
162	  module will be called apm-power.
