config INPUT
tristate "Generic input layer (needed for keyboard, mouse, ...)" if EXPERT
default y
help
Say Y here if you have any input device (mouse, keyboard, tablet,
joystick, steering wheel ...) connected to your system and want
it to be available to applications. This includes standard PS/2
keyboard and mouse.

Say N here if you have a headless (no monitor, no keyboard) system.

More information is available: <file:Documentation/input/input.txt>

If unsure, say Y.

To compile this driver as a module, choose M here: the
module will be called input.

if INPUT

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

If unsure, say N.

To compile this driver as a module, choose M here: the
module will be called ff-memless.

config INPUT_POLLDEV
tristate "Polled input device skeleton"
help
Say Y here if you are using a driver for an input
device that periodically polls hardware state. This
option is only useful for out-of-tree drivers since
in-tree drivers select it automatically.

If unsure, say N.

To compile this driver as a module, choose M here: the
module will be called input-polldev.

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

If unsure, say N.

To compile this driver as a module, choose M here: the
module will be called sparse-keymap.

config INPUT_MATRIXKMAP
tristate "Matrix keymap support library"
help
Say Y here if you are using a driver for an input
device that uses matrix keymap. This option is only
useful for out-of-tree drivers since in-tree drivers
select it automatically.

If unsure, say N.

To compile this driver as a module, choose M here: the
module will be called matrix-keymap.

config INPUT_MOUSEDEV
tristate "Mouse interface"
default y
help
Say Y here if you want your mouse to be accessible as char devices
13:32+ - /dev/input/mouseX and 13:63 - /dev/input/mice as an
emulated IntelliMouse Explorer PS/2 mouse. That way, all user space
programs (including SVGAlib, GPM and X) will be able to use your
mouse.

If unsure, say Y.

To compile this driver as a module, choose M here: the
module will be called mousedev.

config INPUT_MOUSEDEV_PSAUX
bool "Provide legacy /dev/psaux device"
default y
depends on INPUT_MOUSEDEV
help
Say Y here if you want your mouse also be accessible as char device
10:1 - /dev/psaux. The data available through /dev/psaux is exactly
the same as the data from /dev/input/mice.

If unsure, say Y.


config INPUT_MOUSEDEV_SCREEN_X
int "Horizontal screen resolution"
depends on INPUT_MOUSEDEV
default "1024"
help
If you're using a digitizer, or a graphic tablet, and want to use
it as a mouse then the mousedev driver needs to know the X window
screen resolution you are using to correctly scale the data. If
you're not using a digitizer, this value is ignored.

config INPUT_MOUSEDEV_SCREEN_Y
int "Vertical screen resolution"
depends on INPUT_MOUSEDEV
default "768"
help
If you're using a digitizer, or a graphic tablet, and want to use
it as a mouse then the mousedev driver needs to know the X window
screen resolution you are using to correctly scale the data. If
you're not using a digitizer, this value is ignored.

config INPUT_JOYDEV
tristate "Joystick interface"
help
Say Y here if you want your joystick or gamepad to be
accessible as char device 13:0+ - /dev/input/jsX device.

If unsure, say Y.

More information is available: <file:Documentation/input/joystick.txt>

To compile this driver as a module, choose M here: the
module will be called joydev.

config INPUT_EVDEV
tristate "Event interface"
help
Say Y here if you want your input device events be accessible
under char device 13:64+ - /dev/input/eventX in a generic way.

To compile this driver as a module, choose M here: the
module will be called evdev.

config INPUT_EVBUG
tristate "Event debugging"
help
Say Y here if you have a problem with the input subsystem and
want all events (keypresses, mouse movements), to be output to
the system log. While this is useful for debugging, it's also
a security threat - your keypresses include your passwords, of
course.

If unsure, say N.

To compile this driver as a module, choose M here: the
module will be called evbug.

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

To compile this driver as a module, choose M here: the
module will be called apm-power.
