        help
          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
          any ACPI-WMI devices.

          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

          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.

          display state, video output devices in use, whether there is a X
          server running, phase of the moon, and the current mood of
          Schroedinger's cat.  If you can use X.org's RandR to control

          NOTE: access to this feature is limited to processes with the

          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,

          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 option provides a means to manipulate Isolated Memory Regions.
          IMRs are a set of registers that define read and write access masks
          to prohibit certain system agents from accessing memory with 1 KiB
          granularity.

          IMRs make it possible to control read/write access to an address
          by hardware agents inside the SoC. Read and write masks can be
          defined for:
                - eSRAM flush
                - Dirty CPU snoop (write only)
                - RMU access
                - PCI Virtual Channel 0/Virtual Channel 1
                - SMM mode
                - Non SMM mode

          Quark contains a set of eight IMR registers and makes use of those
          registers during its bootup process.

          If you are running on a Galileo/Quark say Y here.

        help
          Intel Calpella platforms support dynamic power sharing between the
          CPU and GPU, maximizing performance in a given TDP.  This driver,
          along with the CPU frequency and i915 drivers, provides that
          functionality.  If in doubt, say Y here; it will only load on
          supported platforms.

          This driver is used to bridge the communications between kernel
          and SCU on some embedded Intel x86 platforms. It also creates
          devices that are connected to the SoC through the SCU.

          The IPC Util driver provides an interface with the SCU enabling
          low level access for debug work and updating the firmware. Say
          N unless you will be doing this on an Intel MID platform.

          This platform driver provides support for various functions via
          the Linux LED framework, GPIO framework, Hardware Monitoring (HWMON)
          and device attributes.

        help
          The Primary to Sideband (P2SB) bridge is an interface to some
          PCI devices connected through it. In particular, SPI NOR controller
          in Intel Apollo Lake SoC is one of such devices.

          The main purpose of this library is to unhide P2SB device in case
          firmware kept it hidden on some platforms in order to access devices
          behind it.
