Input device configuration

menu "Input device support"

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.rst>

  If unsure, say Y.

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

if INPUT

config INPUT_LEDS tristate "Export input device LEDs in sysfs" depends on LEDS_CLASS default INPUT help Say Y here if you would like to export LEDs on input devices as standard LED class devices in sysfs.

  If unsure, say Y.

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

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_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_VIVALDIFMAP tristate help ChromeOS Vivaldi keymap support library. This is a hidden option so that drivers can use common code to parse and expose the vivaldi function row keymap.

comment "Userland interfaces"

config INPUT_MOUSEDEV tristate "Mouse interface" 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" 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/joydev/joystick.rst>

  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_KUNIT_TEST tristate "KUnit tests for Input" if !KUNIT_ALL_TESTS depends on INPUT && KUNIT default KUNIT_ALL_TESTS help Say Y here if you want to build the KUnit tests for the input subsystem.

  If in doubt, say "N".

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.
