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. |

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_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_ISHTP_ECLITE |
|
tristate "Intel ISHTP eclite controller Driver" |
|
depends on INTEL_ISH_HID |
|
depends on ACPI |
|
help |
|
This driver is for accessing the PSE (Programmable Service Engine) - |
|
an Embedded Controller like IP - using ISHTP (Integrated Sensor Hub |
|
Transport Protocol) to get battery, thermal and UCSI (USB Type-C |
|
Connector System Software Interface) related data from the platform. |
|
Users who don't want to use discrete Embedded Controller on Intel's |
|
Elkhartlake platform can leverage this integrated solution of |
|
ECLite which is part of PSE subsystem. |
|
|
|
To compile this driver as a module, choose M here: the module |
|
will be called intel_ishtp_eclite. |
|

tristate "Intel Merrifield Basin Cove power button driver" |
|
depends on INTEL_SOC_PMIC_MRFLD |

|
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. |

|
|
config INTEL_VSEC |
|
tristate "Intel Vendor Specific Extended Capabilities Driver" |

|
DVSEC. |
