	help
	  Say Y here if you want to have control over RF switches
	  found on many WiFi and Bluetooth cards.

	  To compile this driver as a module, choose M here: the
	  module will be called rfkill.

# LED trigger support

	bool
	depends on RFKILL
	depends on LEDS_TRIGGERS = y || RFKILL = LEDS_TRIGGERS
	default y

	depends on RFKILL || !RFKILL
	depends on REGULATOR
	help
          This options enable controlling radio transmitters connected to
          voltage regulator using the regulator framework.

          To compile this driver as a module, choose M here: the module will
          be called rfkill-regulator.

config RFKILL_GPIO
	tristate "GPIO RFKILL driver"
	depends on RFKILL
	depends on GPIOLIB || COMPILE_TEST
	default n
	help
	  If you say yes here you get support of a generic gpio RFKILL
	  driver.
commit-msg'>Some Kabylake desktop processors may not reach max turbo when running in HWP mode, even if running under sustained 100% utilization. This occurs when the HWP.EPP (Energy Performance Preference) is set to "balance_power" (0x80) -- the default on most systems. It occurs because the platform BIOS may erroneously enable an energy-efficiency setting -- MSR_IA32_POWER_CTL BIT-EE, which is not recommended to be enabled on this SKU. On the failing systems, this BIOS issue was not discovered when the desktop motherboard was tested with Windows, because the BIOS also neglects to provide the ACPI/CPPC table, that Windows requires to enable HWP, and so Windows runs in legacy P-state mode, where this setting has no effect. Linux' intel_pstate driver does not require ACPI/CPPC to enable HWP, and so it runs in HWP mode, exposing this incorrect BIOS configuration. There are several ways to address this problem. First, Linux can also run in legacy P-state mode on this system. As intel_pstate is how Linux enables HWP, booting with "intel_pstate=disable" will run in acpi-cpufreq/ondemand legacy p-state mode. Or second, the "performance" governor can be used with intel_pstate, which will modify HWP.EPP to 0. Or third, starting in 4.10, the /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference attribute in can be updated from "balance_power" to "performance". Or fourth, apply this patch, which fixes the erroneous setting of MSR_IA32_POWER_CTL BIT_EE on this model, allowing the default configuration to function as designed.
