- 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.

- config INTEL_IMR
- bool "Intel Isolated Memory Region support"
- depends on X86_INTEL_QUARK && IOSF_MBI
- help
- 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

- functionality. If in doubt, say Y here; it will only load on
- supported platforms.
- 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
