11	default y
12	help
13	  Say Y here if you have any input device (mouse, keyboard, tablet,
14	  joystick, steering wheel ...) connected to your system and want
15	  it to be available to applications. This includes standard PS/2
16	  keyboard and mouse.
17
18	  Say N here if you have a headless (no monitor, no keyboard) system.

43	tristate "Support for memoryless force-feedback devices"
44	help
45	  Say Y here if you have memoryless force-feedback input device
46	  such as Logitech WingMan Force 3D, ThrustMaster FireStorm Dual
47	  Power 2, or similar. You will also need to enable hardware-specific
48	  driver.
49

56	tristate "Sparse keymap support library"
57	help
58	  Say Y here if you are using a driver for an input
59	  device that uses sparse keymap. This option is only
60	  useful for out-of-tree drivers since in-tree drivers
61	  select it automatically.
62

86	  Say Y here if you want your mouse to be accessible as char devices
87	  13:32+ - /dev/input/mouseX and 13:63 - /dev/input/mice as an
88	  emulated IntelliMouse Explorer PS/2 mouse. That way, all user space
89	  programs (including SVGAlib, GPM and X) will be able to use your
90	  mouse.
91
92	  If unsure, say Y.

101	  Say Y here if you want your mouse also be accessible as char device
102	  10:1 - /dev/psaux. The data available through /dev/psaux is exactly
103	  the same as the data from /dev/input/mice.
104

110	default "1024"
111	help
112	  If you're using a digitizer, or a graphic tablet, and want to use
113	  it as a mouse then the mousedev driver needs to know the X window
114	  screen resolution you are using to correctly scale the data. If
115	  you're not using a digitizer, this value is ignored.
116
117config INPUT_MOUSEDEV_SCREEN_Y
118	int "Vertical screen resolution"
119	depends on INPUT_MOUSEDEV
120	default "768"
121	help
122	  If you're using a digitizer, or a graphic tablet, and want to use
123	  it as a mouse then the mousedev driver needs to know the X window
124	  screen resolution you are using to correctly scale the data. If
125	  you're not using a digitizer, this value is ignored.
126
127config INPUT_JOYDEV
128	tristate "Joystick interface"
129	help
130	  Say Y here if you want your joystick or gamepad to be
131	  accessible as char device 13:0+ - /dev/input/jsX device.

140config INPUT_EVDEV
141	tristate "Event interface"
142	help
143	  Say Y here if you want your input device events be accessible
144	  under char device 13:64+ - /dev/input/eventX in a generic way.
145
146	  To compile this driver as a module, choose M here: the
147	  module will be called evdev.
148
149config INPUT_EVBUG
150	tristate "Event debugging"
151	help
152	  Say Y here if you have a problem with the input subsystem and
153	  want all events (keypresses, mouse movements), to be output to
154	  the system log. While this is useful for debugging, it's also
155	  a security threat - your keypresses include your passwords, of
156	  course.
157
158	  If unsure, say N.
159
160	  To compile this driver as a module, choose M here: the

164	tristate "Input Power Event -> APM Bridge" if EXPERT
165	depends on INPUT && APM_EMULATION
166	help
167	  Say Y here if you want suspend key events to trigger a user
168	  requested suspend through APM. This is useful on embedded
169	  systems where such behaviour is desired without userspace
170	  interaction. If unsure, say N.
