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_INTEL source "drivers/platform/x86/intel/atomisp2/Kconfig" source "drivers/platform/x86/intel/int1092/Kconfig" source "drivers/platform/x86/intel/int33fe/Kconfig" source "drivers/platform/x86/intel/int3472/Kconfig" source "drivers/platform/x86/intel/pmc/Kconfig" source "drivers/platform/x86/intel/pmt/Kconfig" source "drivers/platform/x86/intel/speed_select_if/Kconfig" source "drivers/platform/x86/intel/telemetry/Kconfig" config INTEL_HID_EVENT tristate "Intel HID Event" depends on ACPI depends on INPUT depends on I2C select INPUT_SPARSEKMAP help This driver provides support for the Intel HID Event hotkey interface. 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_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_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_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_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_UNCORE_FREQ_CONTROL tristate "Intel Uncore frequency control driver" depends on X86_64 help This driver allows control of Uncore frequency limits on supported server platforms. Uncore frequency controls RING/LLC (last-level cache) clocks. To compile this driver as a module, choose M here: the module will be called intel-uncore-frequency. endif # X86_PLATFORM_DRIVERS_INTEL
