To compile this driver as a module, choose M here: the module will be called wireless-hotkey. config IBM_RTL tristate "Device driver to enable PRTL support" depends on PCI help Enable support for IBM Premium Real Time Mode (PRTM). This module will allow you the enter and exit PRTM in the BIOS via sysfs on platforms that support this feature. System in PRTM will not receive CPU-generated SMIs for recoverable errors. Use of this feature without proper support may void your hardware warranty. If the proper BIOS support is found the driver will load and create /sys/devices/system/ibm_rtl/. The "state" variable will indicate whether or not the BIOS is in PRTM. state = 0 (BIOS SMIs on) state = 1 (BIOS SMIs off) config IDEAPAD_LAPTOP tristate "Lenovo IdeaPad Laptop Extras" depends on ACPI depends on RFKILL && INPUT depends on SERIO_I8042 depends on BACKLIGHT_CLASS_DEVICE depends on ACPI_VIDEO || ACPI_VIDEO = n depends on ACPI_WMI || ACPI_WMI = n select ACPI_PLATFORM_PROFILE select INPUT_SPARSEKMAP select NEW_LEDS select LEDS_CLASS help This is a driver for Lenovo IdeaPad netbooks contains drivers for rfkill switch, hotkey, fan control and backlight control. config SENSORS_HDAPS tristate "Thinkpad Hard Drive Active Protection System (hdaps)" depends on INPUT help This driver provides support for the IBM Hard Drive Active Protection System (hdaps), which provides an accelerometer and other misc. data. ThinkPads starting with the R50, T41, and X40 are supported. The accelerometer data is readable via sysfs. This driver also provides an absolute input class device, allowing the laptop to act as a pinball machine-esque joystick. If your ThinkPad is not recognized by the driver, please update to latest BIOS. This is especially the case for some R52 ThinkPads. Say Y here if you have an applicable laptop and want to experience the awesome power of hdaps. config THINKPAD_ACPI tristate "ThinkPad ACPI Laptop Extras" depends on ACPI depends on ACPI_BATTERY depends on INPUT depends on RFKILL || RFKILL = n depends on ACPI_VIDEO || ACPI_VIDEO = n depends on BACKLIGHT_CLASS_DEVICE depends on I2C select ACPI_PLATFORM_PROFILE select HWMON select NVRAM select NEW_LEDS select LEDS_CLASS select LEDS_TRIGGERS select LEDS_TRIGGER_AUDIO help This is a driver for the IBM and Lenovo ThinkPad laptops. It adds support for Fn-Fx key combinations, Bluetooth control, video output switching, ThinkLight control, UltraBay eject and more. For more information about this driver see <file:Documentation/admin-guide/laptops/thinkpad-acpi.rst> and <http://ibm-acpi.sf.net/> . This driver was formerly known as ibm-acpi. Extra functionality will be available if the rfkill (CONFIG_RFKILL) and/or ALSA (CONFIG_SND) subsystems are available in the kernel. Note that if you want ThinkPad-ACPI to be built-in instead of modular, ALSA and rfkill will also have to be built-in. If you have an IBM or Lenovo ThinkPad laptop, say Y or M here. config THINKPAD_ACPI_ALSA_SUPPORT bool "Console audio control ALSA interface" depends on THINKPAD_ACPI depends on SND depends on SND = y || THINKPAD_ACPI = SND default y help Enables monitoring of the built-in console audio output control (headphone and speakers), which is operated by the mute and (in some ThinkPad models) volume hotkeys. If this option is enabled, ThinkPad-ACPI will export an ALSA card with a single read-only mixer control, which should be used for on-screen-display feedback purposes by the Desktop Environment. Optionally, the driver will also allow software control (the ALSA mixer will be made read-write). Please refer to the driver documentation for details. All IBM models have both volume and mute control. Newer Lenovo models only have mute control (the volume hotkeys are just normal keys and volume control is done through the main HDA mixer). config THINKPAD_ACPI_DEBUGFACILITIES bool "Maintainer debug facilities" depends on THINKPAD_ACPI help Enables extra stuff in the thinkpad-acpi which is completely useless for normal use. Read the driver source to find out what it does. Say N here, unless you were told by a kernel maintainer to do otherwise. config THINKPAD_ACPI_DEBUG bool "Verbose debug mode" depends on THINKPAD_ACPI help Enables extra debugging information, at the expense of a slightly increase in driver size. If you are not sure, say N here. config THINKPAD_ACPI_UNSAFE_LEDS bool "Allow control of important LEDs (unsafe)" depends on THINKPAD_ACPI help Overriding LED state on ThinkPads can mask important firmware alerts (like critical battery condition), or misled the user into damaging the hardware (undocking or ejecting the bay while buses are still active), etc. LED control on the ThinkPad is write-only (with very few exceptions on very ancient models), which makes it impossible to know beforehand if important information will be lost when one changes LED state. Users that know what they are doing can enable this option and the driver will allow control of every LED, including the ones on the dock stations. Never enable this option on a distribution kernel. Say N here, unless you are building a kernel for your own use, and need to control the important firmware LEDs. config THINKPAD_ACPI_VIDEO bool "Video output control support" depends on THINKPAD_ACPI default y help Allows the thinkpad_acpi driver to provide an interface to control the various video output ports. This feature often won't work well, depending on ThinkPad model, display state, video output devices in use, whether there is a X server running, phase of the moon, and the current mood of Schroedinger's cat. If you can use X.org's RandR to control your ThinkPad's video output ports instead of this feature, don't think twice: do it and say N here to save memory and avoid bad interactions with X.org. NOTE: access to this feature is limited to processes with the CAP_SYS_ADMIN capability, to avoid local DoS issues in platforms where it interacts badly with X.org. If you are not sure, say Y here but do try to check if you could be using X.org RandR instead. config THINKPAD_ACPI_HOTKEY_POLL bool "Support NVRAM polling for hot keys" depends on THINKPAD_ACPI default y help Some thinkpad models benefit from NVRAM polling to detect a few of the hot key press events. If you know your ThinkPad model does not need to do NVRAM polling to support any of the hot keys you use, unselecting this option will save about 1kB of memory. ThinkPads T40 and newer, R52 and newer, and X31 and newer are unlikely to need NVRAM polling in their latest BIOS versions. NVRAM polling can detect at most the following keys: ThinkPad/Access IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute, Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12). If you are not sure, say Y here. The driver enables polling only if it is strictly necessary to do so. config THINKPAD_LMI tristate "Lenovo WMI-based systems management driver" depends on ACPI_WMI select FW_ATTR_CLASS help This driver allows changing BIOS settings on Lenovo machines whose BIOS support the WMI interface. To compile this driver as a module, choose M here: the module will be called think-lmi. source "drivers/platform/x86/intel/Kconfig" config MSI_LAPTOP tristate "MSI Laptop Extras" depends on ACPI depends on BACKLIGHT_CLASS_DEVICE depends on ACPI_VIDEO || ACPI_VIDEO = n depends on RFKILL depends on INPUT && SERIO_I8042 select INPUT_SPARSEKMAP help This is a driver for laptops built by MSI (MICRO-STAR INTERNATIONAL): MSI MegaBook S270 (MS-1013) Cytron/TCM/Medion/Tchibo MD96100/SAM2000 It adds support for Bluetooth, WLAN and LCD brightness control.

To compile this driver as a module, choose M here: the module will be called msi-wmi. config XO15_EBOOK tristate "OLPC XO-1.5 ebook switch" depends on OLPC || COMPILE_TEST depends on ACPI && INPUT help Support for the ebook switch on the OLPC XO-1.5 laptop. This switch is triggered as the screen is rotated and folded down to convert the device into ebook form. config XO1_RFKILL tristate "OLPC XO-1 software RF kill switch" depends on OLPC || COMPILE_TEST depends on RFKILL help Support for enabling/disabling the WLAN interface on the OLPC XO-1 laptop. config PCENGINES_APU2 tristate "PC Engines APUv2/3 front button and LEDs driver" depends on INPUT && INPUT_KEYBOARD && GPIOLIB depends on LEDS_CLASS select GPIO_AMD_FCH select KEYBOARD_GPIO_POLLED select LEDS_GPIO help This driver provides support for the front button and LEDs on PC Engines APUv2/APUv3 board. To compile this driver as a module, choose M here: the module will be called pcengines-apuv2. config SAMSUNG_LAPTOP tristate "Samsung Laptop driver" depends on RFKILL || RFKILL = n depends on ACPI_VIDEO || ACPI_VIDEO = n depends on BACKLIGHT_CLASS_DEVICE select LEDS_CLASS select NEW_LEDS help This module implements a driver for a wide range of different Samsung laptops. It offers control over the different function keys, wireless LED, LCD backlight level. It may also provide some sysfs files described in <file:Documentation/ABI/testing/sysfs-driver-samsung-laptop> To compile this driver as a module, choose M here: the module will be called samsung-laptop. config SAMSUNG_Q10 tristate "Samsung Q10 Extras" depends on ACPI select BACKLIGHT_CLASS_DEVICE help This driver provides support for backlight control on Samsung Q10 and related laptops, including Dell Latitude X200. config ACPI_TOSHIBA tristate "Toshiba Laptop Extras" depends on ACPI depends on ACPI_WMI select LEDS_CLASS select NEW_LEDS depends on BACKLIGHT_CLASS_DEVICE depends on INPUT depends on SERIO_I8042 || SERIO_I8042 = n depends on ACPI_VIDEO || ACPI_VIDEO = n depends on RFKILL || RFKILL = n depends on IIO select INPUT_SPARSEKMAP help This driver adds support for access to certain system settings on "legacy free" Toshiba laptops. These laptops can be recognized by their lack of a BIOS setup menu and APM support. On these machines, all system configuration is handled through the ACPI. This driver is required for access to controls not covered by the general ACPI drivers, such as LCD brightness, video output, etc. This driver differs from the non-ACPI Toshiba laptop driver (located under "Processor type and features") in several aspects. Configuration is accessed by reading and writing text files in the /proc tree instead of by program interface to /dev. Furthermore, no power management functions are exposed, as those are handled by the general ACPI drivers. More information about this driver is available at <http://memebeam.org/toys/ToshibaAcpiDriver>. If you have a legacy free Toshiba laptop (such as the Libretto L1 series), say Y. config TOSHIBA_BT_RFKILL tristate "Toshiba Bluetooth RFKill switch support" depends on ACPI depends on RFKILL || RFKILL = n help This driver adds support for Bluetooth events for the RFKill switch on modern Toshiba laptops with full ACPI support and an RFKill switch. This driver handles RFKill events for the TOS6205 Bluetooth, and re-enables it when the switch is set back to the 'on' position. If you have a modern Toshiba laptop with a Bluetooth and an RFKill switch (such as the Portege R500), say Y. config TOSHIBA_HAPS tristate "Toshiba HDD Active Protection Sensor" depends on ACPI help This driver adds support for the built-in accelerometer found on recent Toshiba laptops equipped with HID TOS620A device. This driver receives ACPI notify events 0x80 when the sensor detects a sudden move or a harsh vibration, as well as an ACPI notify event 0x81 whenever the movement or vibration has been stabilized. Also provides sysfs entries to get/set the desired protection level and resetting the HDD protection interface. If you have a recent Toshiba laptop with a built-in accelerometer device, say Y. config TOSHIBA_WMI tristate "Toshiba WMI Hotkeys Driver (EXPERIMENTAL)" depends on ACPI_WMI depends on INPUT select INPUT_SPARSEKMAP help This driver adds hotkey monitoring support to some Toshiba models that manage the hotkeys via WMI events. WARNING: This driver is incomplete as it lacks a proper keymap and the *notify function only prints the ACPI event type value. Be warned that you will need to provide some information if you have a Toshiba model with WMI event hotkeys and want to help with the development of this driver. If you have a WMI-based hotkeys Toshiba laptop, say Y or M here. config ACPI_CMPC tristate "CMPC Laptop Extras" depends on ACPI && INPUT depends on RFKILL || RFKILL=n select BACKLIGHT_CLASS_DEVICE help Support for Intel Classmate PC ACPI devices, including some keys as input device, backlight device, tablet and accelerometer devices. config COMPAL_LAPTOP tristate "Compal (and others) Laptop Extras" depends on ACPI depends on BACKLIGHT_CLASS_DEVICE depends on ACPI_VIDEO || ACPI_VIDEO = n depends on RFKILL depends on HWMON depends on POWER_SUPPLY help This is a driver for laptops built by Compal, and some models by other brands (e.g. Dell, Toshiba).
