| Say Y here to get to see options for device drivers for |
| various Intel x86 platforms, including vendor-specific |
| drivers. This option alone does not add any kernel code. |
| |
| If you say N, all options in this submenu will be skipped |

| help |
| This driver provides support for the Intel HID Event hotkey interface. |

| 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. |
| |

| 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_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_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. |
