It gives access to some extra laptop functionalities like Bluetooth, screen brightness control, Fn keys and allows powering on/off some devices. Read for more information. config SONYPI_COMPAT bool "Sonypi compatibility" depends on SONY_LAPTOP ---help--- Build the sonypi driver compatibility code into the sony-laptop driver. config IDEAPAD_LAPTOP tristate "Lenovo IdeaPad Laptop Extras" depends on ACPI depends on RFKILL && INPUT select INPUT_SPARSEKMAP help This is a driver for the rfkill switches on Lenovo IdeaPad netbooks. config THINKPAD_ACPI tristate "ThinkPad ACPI Laptop Extras" depends on ACPI depends on INPUT depends on RFKILL || RFKILL = n select BACKLIGHT_LCD_SUPPORT select BACKLIGHT_CLASS_DEVICE select HWMON select NVRAM select NEW_LEDS select LEDS_CLASS ---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 and . 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 default n ---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 default n ---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 default n ---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 SENSORS_HDAPS tristate "Thinkpad Hard Drive Active Protection System (hdaps)" depends on INPUT && X86 select INPUT_POLLDEV default n 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 INTEL_MENLOW tristate "Thermal Management driver for Intel menlow platform" depends on ACPI_THERMAL select THERMAL ---help--- ACPI thermal management enhancement driver on Intel Menlow platform. If unsure, say N. config EEEPC_LAPTOP tristate "Eee PC Hotkey Driver (EXPERIMENTAL)" depends on ACPI depends on INPUT depends on EXPERIMENTAL depends on RFKILL || RFKILL = n depends on HOTPLUG_PCI select BACKLIGHT_CLASS_DEVICE select HWMON select LEDS_CLASS select NEW_LEDS select INPUT_SPARSEKMAP ---help--- This driver supports the Fn-Fx keys on Eee PC laptops. It also gives access to some extra laptop functionalities like Bluetooth, backlight and allows powering on/off some other devices. If you have an Eee PC laptop, say Y or M here. If this driver doesn't work on your Eee PC, try eeepc-wmi instead. config ASUS_WMI tristate "ASUS WMI Driver (EXPERIMENTAL)" depends on ACPI_WMI depends on INPUT depends on HWMON depends on EXPERIMENTAL depends on BACKLIGHT_CLASS_DEVICE depends on RFKILL || RFKILL = n depends on HOTPLUG_PCI select INPUT_SPARSEKMAP select LEDS_CLASS select NEW_LEDS ---help--- Say Y here if you have a WMI aware Asus laptop (like Eee PCs or new Asus Notebooks). To compile this driver as a module, choose M here: the module will be called asus-wmi. config ASUS_NB_WMI tristate "Asus Notebook WMI Driver (EXPERIMENTAL)" depends on ASUS_WMI ---help--- This is a driver for newer Asus notebooks. It adds extra features like wireless radio and bluetooth control, leds, hotkeys, backlight... For more informations, see If you have an ACPI-WMI compatible Asus Notebook, say Y or M here. config EEEPC_WMI tristate "Eee PC WMI Driver (EXPERIMENTAL)" depends on ASUS_WMI ---help--- This is a driver for newer Eee PC laptops. It adds extra features like wireless radio and bluetooth control, leds, hotkeys, backlight... For more informations, see If you have an ACPI-WMI compatible Eee PC laptop (>= 1000), say Y or M here. config ACPI_WMI tristate "WMI" depends on ACPI help This driver adds support for the ACPI-WMI (Windows Management Instrumentation) mapper device (PNP0C14) found on some systems. ACPI-WMI is a proprietary extension to ACPI to expose parts of the ACPI firmware to userspace - this is done through various vendor defined methods and data blocks in a PNP0C14 device, which are then made available for userspace to call. The implementation of this in Linux currently only exposes this to other kernel space drivers. This driver is a required dependency to build the firmware specific drivers needed on many machines, including Acer and HP laptops. It is safe to enable this driver even if your DSDT doesn't define any ACPI-WMI devices. config MSI_WMI tristate "MSI WMI extras" depends on ACPI_WMI depends on INPUT depends on BACKLIGHT_CLASS_DEVICE select INPUT_SPARSEKMAP help Say Y here if you want to support WMI-based hotkeys on MSI laptops. To compile this driver as a module, choose M here: the module will be called msi-wmi. config ACPI_ASUS tristate "ASUS/Medion Laptop Extras (DEPRECATED)" depends on ACPI select BACKLIGHT_CLASS_DEVICE ---help--- This driver provides support for extra features of ACPI-compatible ASUS laptops. As some of Medion laptops are made by ASUS, it may also support some Medion laptops (such as 9675 for example). It makes all the extra buttons generate standard ACPI events that go through /proc/acpi/events, and (on some models) adds support for changing the display brightness and output, switching the LCD backlight on and off, and most importantly, allows you to blink those fancy LEDs intended for reporting mail and wireless status. Note: display switching code is currently considered EXPERIMENTAL, toying with these values may even lock your machine. All settings are changed via /proc/acpi/asus directory entries. Owner and group for these entries can be set with asus_uid and asus_gid parameters. More information and a userspace daemon for handling the extra buttons at . If you have an ACPI-compatible ASUS laptop, say Y or M here. This driver is still under development, so if your laptop is unsupported or something works not quite as expected, please use the mailing list available on the above page (acpi4asus-user@lists.sourceforge.net). NOTE: This driver is deprecated and will probably be removed soon, use asus-laptop instead. config TOPSTAR_LAPTOP tristate "Topstar Laptop Extras" depends on ACPI depends on INPUT select INPUT_SPARSEKMAP ---help--- This driver adds support for hotkeys found on Topstar laptops. If you have a Topstar laptop, say Y or M here. config ACPI_TOSHIBA tristate "Toshiba Laptop Extras" depends on ACPI select LEDS_CLASS select NEW_LEDS depends on BACKLIGHT_CLASS_DEVICE depends on INPUT depends on RFKILL || RFKILL = n select INPUT_POLLDEV 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 . 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 ---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 ACPI_CMPC tristate "CMPC Laptop Extras" depends on X86 && ACPI depends on RFKILL || RFKILL=n select INPUT select BACKLIGHT_CLASS_DEVICE default n help Support for Intel Classmate PC ACPI devices, including some keys as input device, backlight device, tablet and accelerometer devices. config INTEL_SCU_IPC bool "Intel SCU IPC Support" depends on X86_MRST default y ---help--- IPC is used to bridge the communications between kernel and SCU on some embedded Intel x86 platforms. This is not needed for PC-type machines. config INTEL_SCU_IPC_UTIL tristate "Intel SCU IPC utility driver" depends on INTEL_SCU_IPC default y ---help--- The IPC Util driver provides an interface with the SCU enabling low level access for debug work and updating the firmware. Say N unless you will be doing this on an Intel MID platform. config GPIO_INTEL_PMIC bool "Intel PMIC GPIO support" depends on INTEL_SCU_IPC && GPIOLIB ---help--- Say Y here to support GPIO via the SCU IPC interface on Intel MID platforms. config INTEL_MID_POWER_BUTTON tristate "power button driver for Intel MID platforms" depends on INTEL_SCU_IPC && INPUT help This driver handles the power button on the Intel MID platforms. If unsure, say N. config INTEL_MFLD_THERMAL tristate "Thermal driver for Intel Medfield platform" depends on INTEL_SCU_IPC && THERMAL help Say Y here to enable thermal driver support for the Intel Medfield platform. config RAR_REGISTER bool "Restricted Access Region Register Driver" depends on PCI && X86_MRST default n ---help--- This driver allows other kernel drivers access to the contents of the restricted access region control registers. The restricted access region control registers (rar_registers) are used to pass address and locking information on restricted access regions to other drivers that use restricted access regions. The restricted access regions are regions of memory on the Intel MID Platform that are not accessible to the x86 processor, but are accessible to dedicated processors on board peripheral devices. The purpose of the restricted access regions is to protect sensitive data from compromise by unauthorized programs running on the x86 processor. config INTEL_IPS tristate "Intel Intelligent Power Sharing" depends on ACPI ---help--- Intel Calpella platforms support dynamic power sharing between the CPU and GPU, maximizing performance in a given TDP. This driver, along with the CPU frequency and i915 drivers, provides that functionality. If in doubt, say Y here; it will only load on supported platforms. config IBM_RTL tristate "Device driver to enable PRTL support" depends on X86 && 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 XO1_RFKILL tristate "OLPC XO-1 software RF kill switch" depends on OLPC depends on RFKILL ---help--- Support for enabling/disabling the WLAN interface on the OLPC XO-1 laptop. config XO15_EBOOK tristate "OLPC XO-1.5 ebook switch" depends on ACPI && INPUT ---help--- Support for the ebook switch on the OLPC XO-1.5 laptop.
