Some laptops require this driver for hotkey support. To compile this driver as a module, choose M here: the module will be called intel_hid. config INTEL_VBTN tristate "Intel Virtual Button" depends on ACPI depends on INPUT depends on I2C select INPUT_SPARSEKMAP help This driver provides support for the Intel Virtual Button interface. Some laptops require this driver for power button support. To compile this driver as a module, choose M here: the module will be called intel_vbtn. config INTEL_INT0002_VGPIO tristate "Intel ACPI INT0002 Virtual GPIO driver" depends on GPIOLIB && ACPI && PM_SLEEP select GPIOLIB_IRQCHIP help Some peripherals on Bay Trail and Cherry Trail platforms signal a Power Management Event (PME) to the Power Management Controller (PMC) to wakeup the system. When this happens software needs to explicitly clear the PME bus 0 status bit in the GPE0a_STS register to avoid an IRQ storm on IRQ 9. This is modelled in ACPI through the INT0002 ACPI device, which is called a "Virtual GPIO controller" in ACPI because it defines the event handler to call when the PME triggers through _AEI and _L02 methods as would be done for a real GPIO interrupt in ACPI. To compile this driver as a module, choose M here: the module will be called intel_int0002_vgpio. config INTEL_OAKTRAIL tristate "Intel Oaktrail Platform Extras" depends on ACPI depends on ACPI_VIDEO || ACPI_VIDEO=n depends on RFKILL && BACKLIGHT_CLASS_DEVICE && ACPI help Intel Oaktrail platform need this driver to provide interfaces to enable/disable the Camera, WiFi, BT etc. devices. If in doubt, say Y here; it will only load on supported platforms. config INTEL_BXTWC_PMIC_TMU tristate "Intel Broxton Whiskey Cove TMU Driver" depends on INTEL_SOC_PMIC_BXTWC depends on MFD_INTEL_PMC_BXT select REGMAP help Select this driver to use Intel Broxton Whiskey Cove PMIC TMU feature. This driver enables the alarm wakeup functionality in the TMU unit of Whiskey Cove PMIC. config INTEL_BYTCRC_PWRSRC tristate "Intel Bay Trail Crystal Cove power source driver" depends on INTEL_SOC_PMIC help This option adds a power source driver for Crystal Cove PMICs on Intel Bay Trail devices. To compile this driver as a module, choose M here: the module will be called intel_bytcrc_pwrsrc. config INTEL_CHTDC_TI_PWRBTN tristate "Intel Cherry Trail Dollar Cove TI power button driver" depends on INTEL_SOC_PMIC_CHTDC_TI depends on INPUT help This option adds a power button driver for Dollar Cove TI PMIC on Intel Cherry Trail devices. To compile this driver as a module, choose M here: the module will be called intel_chtdc_ti_pwrbtn. config INTEL_CHTWC_INT33FE tristate "Intel Cherry Trail Whiskey Cove ACPI INT33FE Driver" depends on X86 && ACPI && I2C && REGULATOR depends on CHARGER_BQ24190=y || (CHARGER_BQ24190=m && m) depends on USB_ROLES_INTEL_XHCI=y || (USB_ROLES_INTEL_XHCI=m && m) depends on TYPEC_MUX_PI3USB30532=y || (TYPEC_MUX_PI3USB30532=m && m) help This driver add support for the Intel Cherry Trail Whiskey Cove INT33FE ACPI device found on the GPD win and the GPD pocket. The INT33FE ACPI device on these mini laptops contains I2cSerialBusV2 resources for a MAX17042 Fuel Gauge, FUSB302 USB Type-C Controller and PI3USB30532 USB switch. This driver instantiates i2c-clients for these, so that standard i2c drivers for these chips can bind to the them. If you enable this driver it is advised to also select CONFIG_TYPEC_FUSB302=m, CONFIG_TYPEC_MUX_PI3USB30532=m and CONFIG_BATTERY_MAX17042=m. config INTEL_ISHTP_ECLITE tristate "Intel ISHTP eclite controller Driver" depends on INTEL_ISH_HID depends on ACPI help This driver is for accessing the PSE (Programmable Service Engine) - an Embedded Controller like IP - using ISHTP (Integrated Sensor Hub Transport Protocol) to get battery, thermal and UCSI (USB Type-C Connector System Software Interface) related data from the platform. Users who don't want to use discrete Embedded Controller on Intel's Elkhartlake platform can leverage this integrated solution of ECLite which is part of PSE subsystem. To compile this driver as a module, choose M here: the module will be called intel_ishtp_eclite. config INTEL_MRFLD_PWRBTN tristate "Intel Merrifield Basin Cove power button driver" depends on INTEL_SOC_PMIC_MRFLD depends on INPUT help This option adds a power button driver for Basin Cove PMIC on Intel Merrifield devices. To compile this driver as a module, choose M here: the module will be called intel_mrfld_pwrbtn. config INTEL_PUNIT_IPC tristate "Intel P-Unit IPC Driver" help This driver provides support for Intel P-Unit Mailbox IPC mechanism, which is used to bridge the communications between kernel and P-Unit. config INTEL_RST tristate "Intel Rapid Start Technology Driver" depends on ACPI help This driver provides support for modifying parameters on systems equipped with Intel's Rapid Start Technology. When put in an ACPI sleep state, these devices will wake after either a configured timeout or when the system battery reaches a critical state, automatically copying memory contents to disk. On resume, the firmware will copy the memory contents back to RAM and resume the OS as usual. config INTEL_SDSI tristate "Intel On Demand (Software Defined Silicon) Driver" depends on INTEL_VSEC depends on X86_64 help This driver enables access to the Intel On Demand (formerly Software Defined Silicon) interface used to provision silicon features with an authentication certificate and capability license. To compile this driver as a module, choose M here: the module will be called intel_sdsi. config INTEL_SMARTCONNECT tristate "Intel Smart Connect disabling driver" depends on ACPI help Intel Smart Connect is a technology intended to permit devices to update state by resuming for a short period of time at regular intervals. If a user enables this functionality under Windows and then reboots into Linux, the system may remain configured to resume on suspend. In the absence of any userspace to support it, the system will then remain awake until something triggers another suspend. This driver checks to determine whether the device has Intel Smart Connect enabled, and if so disables it. config INTEL_TPMI tristate "Intel Topology Aware Register and PM Capsule Interface (TPMI)" depends on INTEL_VSEC depends on X86_64 help The Intel Topology Aware Register and PM Capsule Interface (TPMI), provides enumerable MMIO interface for power management features. This driver creates devices, so that other PM feature driver can be loaded for PM specific feature operation. To compile this driver as a module, choose M here: the module will be called intel_vsec_tpmi. config INTEL_TURBO_MAX_3 bool "Intel Turbo Boost Max Technology 3.0 enumeration driver" depends on X86_64 && SCHED_MC_PRIO help This driver reads maximum performance ratio of each CPU and set up the scheduler priority metrics. In this way scheduler can prefer CPU with higher performance to schedule tasks. This driver is only required when the system is not using Hardware P-States (HWP). In HWP mode, priority can be read from ACPI tables. config INTEL_VSEC tristate "Intel Vendor Specific Extended Capabilities Driver" depends on PCI select AUXILIARY_BUS help Adds support for feature drivers exposed using Intel PCIe VSEC and DVSEC. To compile this driver as a module, choose M here: the module will be called intel_vsec.
