          This is a driver for the IBM and Lenovo ThinkPad laptops. It adds
          support for Fn-Fx key combinations, Bluetooth control, video
          output switching, ThinkLight control, UltraBay eject and more.
          For more information about this driver see
          <file:Documentation/laptops/thinkpad-acpi.txt> and
          <http://ibm-acpi.sf.net/> .

          This driver was formerly known as ibm-acpi.

          Extra functionality will be available if the rfkill (CONFIG_RFKILL)
          and/or ALSA (CONFIG_SND) subsystems are available in the kernel.
          Note that if you want ThinkPad-ACPI to be built-in instead of
          modular, ALSA and rfkill will also have to be built-in.

          If you have an IBM or Lenovo ThinkPad laptop, say Y or M here.

config THINKPAD_ACPI_ALSA_SUPPORT

        default y
        ---help---
          Enables monitoring of the built-in console audio output control
          (headphone and speakers), which is operated by the mute and (in
          some ThinkPad models) volume hotkeys.

          If this option is enabled, ThinkPad-ACPI will export an ALSA card
          with a single read-only mixer control, which should be used for
          on-screen-display feedback purposes by the Desktop Environment.

          Optionally, the driver will also allow software control (the
          ALSA mixer will be made read-write).  Please refer to the driver
          documentation for details.

          All IBM models have both volume and mute control.  Newer Lenovo
          models only have mute control (the volume hotkeys are just normal
          keys and volume control is done through the main HDA mixer).

config THINKPAD_ACPI_DEBUGFACILITIES

          Enables extra stuff in the thinkpad-acpi which is completely useless

          Say N here, unless you were told by a kernel maintainer to do
          otherwise.

config THINKPAD_ACPI_DEBUG
        bool "Verbose debug mode"
        depends on THINKPAD_ACPI
        ---help---
          Enables extra debugging information, at the expense of a slightly

config THINKPAD_ACPI_UNSAFE_LEDS
        bool "Allow control of important LEDs (unsafe)"
        depends on THINKPAD_ACPI
        ---help---
          Overriding LED state on ThinkPads can mask important
          firmware alerts (like critical battery condition), or misled
          the user into damaging the hardware (undocking or ejecting
          the bay while buses are still active), etc.

          LED control on the ThinkPad is write-only (with very few
          exceptions on very ancient models), which makes it
          impossible to know beforehand if important information will
          be lost when one changes LED state.

          Users that know what they are doing can enable this option
          and the driver will allow control of every LED, including
          the ones on the dock stations.

          Never enable this option on a distribution kernel.

          Say N here, unless you are building a kernel for your own
          use, and need to control the important firmware LEDs.

config THINKPAD_ACPI_VIDEO
        bool "Video output control support"
        depends on THINKPAD_ACPI
        default y
        ---help---
          Allows the thinkpad_acpi driver to provide an interface to control
          the various video output ports.

          This feature often won't work well, depending on ThinkPad model,
          display state, video output devices in use, whether there is a X
          server running, phase of the moon, and the current mood of

          Some thinkpad models benefit from NVRAM polling to detect a few of
          the hot key press events.  If you know your ThinkPad model does not
          need to do NVRAM polling to support any of the hot keys you use,
          unselecting this option will save about 1kB of memory.

          ThinkPads T40 and newer, R52 and newer, and X31 and newer are
          unlikely to need NVRAM polling in their latest BIOS versions.

          NVRAM polling can detect at most the following keys: ThinkPad/Access
          IBM, Zoom, Switch Display (fn+F7), ThinkLight, Volume up/down/mute,
          Brightness up/down, Display Expand (fn+F8), Hibernate (fn+F12).

          This driver adds support for the ACPI-WMI (Windows Management
          Instrumentation) mapper device (PNP0C14) found on some systems.

          ACPI-WMI is a proprietary extension to ACPI to expose parts of the
          ACPI firmware to userspace - this is done through various vendor
          defined methods and data blocks in a PNP0C14 device, which are then
          made available for userspace to call.

          The implementation of this in Linux currently only exposes this to
          other kernel space drivers.

          This driver is a required dependency to build the firmware specific
          drivers needed on many machines, including Acer and HP laptops.

          It is safe to enable this driver even if your DSDT doesn't define

          their lack of a BIOS setup menu and APM support.

          On these machines, all system configuration is handled through the
          ACPI.  This driver is required for access to controls not covered
          by the general ACPI drivers, such as LCD brightness, video output,
          etc.

          This driver differs from the non-ACPI Toshiba laptop driver (located

          Configuration is accessed by reading and writing text files in the
          /proc tree instead of by program interface to /dev.  Furthermore, no
          power management functions are exposed, as those are handled by the

        depends on ACPI
        ---help---
          This driver provides support for modifying paramaters 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 PVPANIC
        tristate "pvpanic device support"
        depends on ACPI
        ---help---
          This driver provides support for the pvpanic device.  pvpanic is

          This driver provides interfaces to configure and use
          telemetry for INTEL SoC from APL onwards. It is also
          used to get various SoC events and parameters
          directly via debugfs files. Various tools may use
          this interface for SoC state monitoring.

        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.

        depends on ACPI && DMI && I2C=y && TOUCHSCREEN_SILEAD
        ---help---
          Certain ACPI based tablets with Silead touchscreens do not have
          enough data in ACPI tables for the touchscreen driver to handle
          the touchscreen properly, as OEMs expected the data to be baked
          into the tablet model specific version of the driver shipped
          with the OS-image for the device. This option supplies the missing
          information. Enable this for x86 tablets with Silead touchscreens.
