menuconfig X86_PLATFORM_DRIVERS_INTEL
bool "Intel x86 Platform Specific Device Drivers"
default y
help
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
and disabled.

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 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.
