menuconfig X86_PLATFORM_DEVICES
	bool "X86 Platform Specific Device Drivers"
	default y
	depends on X86
	help
	  Say Y here to get to see options for device drivers for various
	  x86 platforms, including vendor-specific laptop extension drivers.
	  This option alone does not add any kernel code.

	  If you say N, all options in this submenu will be skipped and disabled.

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 WMI_BMOF
	tristate "WMI embedded Binary MOF driver"
	depends on ACPI_WMI
	default ACPI_WMI
	help
	  Say Y here if you want to be able to read a firmware-embedded
	  WMI Binary MOF (Managed Object Format) data. Using this requires
	  userspace tools and may be rather tedious.

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

config HUAWEI_WMI

	select LEDS_CLASS
	select NEW_LEDS
	help
	  This driver provides support for Huawei WMI hotkeys, battery charge
	  control, fn-lock, mic-mute LED, and other extra features.

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

config UV_SYSFS
	tristate "Sysfs structure for UV systems"
	depends on X86_UV
	depends on SYSFS
	help
	  This driver supports a sysfs tree describing information about
	  UV systems at /sys/firmware/sgi_uv/.

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

config MXM_WMI
       tristate "WMI support for MXM Laptop Graphics"

	help
	  This driver provides a sysfs backlight interface for notebook systems
	  which are equipped with NVIDIA hybrid graphics and drive LCD backlight
	  levels through the Embedded Controller (EC).

	  Say Y or M here if you want to control the backlight on a notebook
	  system with an EC-driven backlight.

	  If you choose to compile this driver as a module the module will be
	  called nvidia-wmi-ec-backlight.

config XIAOMI_WMI
	tristate "Xiaomi WMI key driver"
	depends on ACPI_WMI
	depends on INPUT
	help
	  Say Y here if you want to support WMI-based keys on Xiaomi notebooks.

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

config GIGABYTE_WMI
	tristate "Gigabyte WMI temperature driver"
	depends on ACPI_WMI

config ACERHDF
	tristate "Acer Aspire One temperature and fan driver"
	depends on ACPI_EC && THERMAL
	select THERMAL_GOV_BANG_BANG
	help
	  This is a driver for Acer Aspire One netbooks. It allows to access
	  the temperature sensor and to control the fan.

	  After loading this driver the BIOS is still in control of the fan.
	  To let the kernel handle the fan, do:
	  echo -n enabled > /sys/class/thermal/thermal_zoneN/mode
	  where N=0,1,2... depending on the number of thermal nodes and the
	  detection order of your particular system.  The "type" parameter
	  in the same node directory will tell you if it is "acerhdf".

	  For more information about this driver see
	  <https://piie.net/files/acerhdf_README.txt>

	  If you have an Acer Aspire One netbook, say Y or M
	  here.
