menuconfig X86_PLATFORM_DRIVERS_DELL
bool "Dell X86 Platform Specific Device Drivers"
help
Say Y here to get to see options for device drivers for various
Dell 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 ALIENWARE_WMI
tristate "Alienware Special feature control"
default m
depends on ACPI
depends on LEDS_CLASS
depends on NEW_LEDS
depends on ACPI_WMI
help
This is a driver for controlling Alienware BIOS driven
features. It exposes an interface for controlling the AlienFX
zones on Alienware machines that don't contain a dedicated AlienFX
USB MCU such as the X51 and X51-R2.
config DCDBAS
tristate "Dell Systems Management Base Driver"
default m
depends on X86
help
The Dell Systems Management Base Driver provides a sysfs interface
for systems management software to perform System Management
Interrupts (SMIs) and Host Control Actions (system power cycle or
power off after OS shutdown) on certain Dell systems.
See <file:Documentation/userspace-api/dcdbas.rst> for more details on the driver
and the Dell systems on which Dell systems management software makes
use of this driver.
Say Y or M here to enable the driver for use by Dell systems
management software such as Dell OpenManage.

help
This driver adds support for rfkill and backlight control to Dell
laptops (except for some models covered by the Compal driver).
config DELL_RBU
tristate "BIOS update support for DELL systems via sysfs"
default m
depends on X86
select FW_LOADER
select FW_LOADER_USER_HELPER
help
Say m if you want to have the option of updating the BIOS for your
DELL system. Note you need a Dell OpenManage or Dell Update package (DUP)
supporting application to communicate with the BIOS regarding the new
image for the image update to take effect.
See <file:Documentation/admin-guide/dell_rbu.rst> for more details on the driver.
config DELL_RBTN
tristate "Dell Airplane Mode Switch driver"
default m
depends on ACPI
depends on INPUT
depends on RFKILL
help
Say Y here if you want to support Dell Airplane Mode Switch ACPI
device on Dell laptops. Sometimes it has names: DELLABCE or DELRBTN.
This driver register rfkill device or input hotkey device depending
on hardware type (hw switch slider or keyboard toggle button). For
rfkill devices it receive HW switch events and set correct hard
rfkill state.
To compile this driver as a module, choose M here: the module will
be called dell-rbtn.
config DELL_PC
tristate "Dell PC Extras"
default m
depends on ACPI
depends on DMI
depends on DELL_SMBIOS
select ACPI_PLATFORM_PROFILE
help
This driver adds support for controlling the fan modes via platform_profile
on supported Dell systems regardless of formfactor.
Module will simply do nothing if thermal management commands are not
supported.
#
# The DELL_SMBIOS driver depends on ACPI_WMI and/or DCDBAS if those
# backends are selected. The "depends" line prevents a configuration
# where DELL_SMBIOS=y while either of those dependencies =m.

config DELL_SMBIOS
tristate "Dell SMBIOS driver"
default m
depends on DCDBAS || DCDBAS=n
depends on ACPI_WMI || ACPI_WMI=n
help
This provides support for the Dell SMBIOS calling interface.
If you have a Dell computer you should enable this option.
Be sure to select at least one backend for it to work properly.
config DELL_SMBIOS_WMI

default y
depends on ACPI_WMI
select DELL_WMI_DESCRIPTOR
depends on DELL_SMBIOS
help
This provides an implementation for the Dell SMBIOS calling interface
communicated over ACPI-WMI.
If you have a Dell computer from >2007 you should say Y here.
If you aren't sure and this module doesn't work for your computer
it just won't load.
config DELL_SMBIOS_SMM
bool "Dell SMBIOS driver SMM backend"
default y
depends on DCDBAS
depends on DELL_SMBIOS
help
This provides an implementation for the Dell SMBIOS calling interface
communicated over SMI/SMM.
If you have a Dell computer from <=2017 you should say Y here.
If you aren't sure and this module doesn't work for your computer
it just won't load.
