# SPDX-License-Identifier: GPL-2.0-only # # 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. comment "Input Device Drivers" source "drivers/input/keyboard/Kconfig" source "drivers/input/mouse/Kconfig" source "drivers/input/joystick/Kconfig" source "drivers/input/tablet/Kconfig" source "drivers/input/touchscreen/Kconfig" source "drivers/input/misc/Kconfig" source "drivers/input/rmi4/Kconfig" endif menu "Hardware I/O ports" source "drivers/input/serio/Kconfig" source "drivers/input/gameport/Kconfig" endmenu endmenu
