This option alone does not add any kernel code. If you say N, all options in this submenu will be skipped and disabled. if X86_PLATFORM_DRIVERS_DELL 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/driver-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. config DELL_LAPTOP tristate "Dell Laptop Extras" default m depends on DMI depends on BACKLIGHT_CLASS_DEVICE depends on ACPI_VIDEO || ACPI_VIDEO = n depends on RFKILL || RFKILL = n depends on DELL_WMI || DELL_WMI = n depends on SERIO_I8042 depends on DELL_SMBIOS select POWER_SUPPLY select LEDS_CLASS select NEW_LEDS select LEDS_TRIGGERS select LEDS_TRIGGER_AUDIO 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. # # 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 bool "Dell SMBIOS driver WMI backend" 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. config DELL_SMO8800 tristate "Dell Latitude freefall driver (ACPI SMO88XX)" default m depends on ACPI || COMPILE_TEST help Say Y here if you want to support SMO88XX freefall devices on Dell Latitude laptops. To compile this driver as a module, choose M here: the module will be called dell-smo8800. config DELL_WMI tristate "Dell WMI notifications" default m depends on ACPI_WMI depends on DMI depends on INPUT depends on ACPI_VIDEO || ACPI_VIDEO = n depends on DELL_SMBIOS select DELL_WMI_DESCRIPTOR select INPUT_SPARSEKMAP help Say Y here if you want to support WMI-based hotkeys on Dell laptops. To compile this driver as a module, choose M here: the module will be called dell-wmi. config DELL_WMI_PRIVACY bool "Dell WMI Hardware Privacy Support" depends on LEDS_TRIGGER_AUDIO = y || DELL_WMI = LEDS_TRIGGER_AUDIO depends on DELL_WMI help This option adds integration with the "Dell Hardware Privacy" feature of Dell laptops to the dell-wmi driver. config DELL_WMI_AIO tristate "WMI Hotkeys for Dell All-In-One series" default m depends on ACPI_WMI depends on INPUT select INPUT_SPARSEKMAP help Say Y here if you want to support WMI-based hotkeys on Dell All-In-One machines. To compile this driver as a module, choose M here: the module will be called dell-wmi-aio. config DELL_WMI_DESCRIPTOR tristate default n depends on ACPI_WMI config DELL_WMI_DDV tristate "Dell WMI sensors Support" default m depends on ACPI_WMI depends on ACPI_BATTERY || HWMON help This option adds support for WMI-based fan and thermal sensors found on some Dell notebooks. It also supports various WMI-based battery extras like reading of the battery temperature and ePPID. To compile this drivers as a module, choose M here: the module will be called dell-wmi-ddv. config DELL_WMI_LED tristate "External LED on Dell Business Netbooks" default m depends on LEDS_CLASS depends on ACPI_WMI help This adds support for the Latitude 2100 and similar notebooks that have an external LED. config DELL_WMI_SYSMAN tristate "Dell WMI-based Systems management driver" default m depends on ACPI_WMI depends on DMI select NLS select FW_ATTR_CLASS help This driver allows changing BIOS settings on many Dell machines from 2018 and newer without the use of any additional software. To compile this driver as a module, choose M here: the module will be called dell-wmi-sysman. endif # X86_PLATFORM_DRIVERS_DELL
