18 config INTEL_HID_EVENT
19 tristate "Intel HID Event"
23 select INPUT_SPARSEKMAP
25 This driver provides support for the Intel HID Event hotkey interface.
26 Some laptops require this driver for hotkey support.
28 To compile this driver as a module, choose M here: the module will
32 tristate "Intel Virtual Button"

44 config INTEL_INT0002_VGPIO
45 tristate "Intel ACPI INT0002 Virtual GPIO driver"
46 depends on GPIOLIB && ACPI && PM_SLEEP
47 select GPIOLIB_IRQCHIP
49 Some peripherals on Bay Trail and Cherry Trail platforms signal a
50 Power Management Event (PME) to the Power Management Controller (PMC)
51 to wakeup the system. When this happens software needs to explicitly
52 clear the PME bus 0 status bit in the GPE0a_STS register to avoid an
55 This is modelled in ACPI through the INT0002 ACPI device, which is
56 called a "Virtual GPIO controller" in ACPI because it defines the
57 event handler to call when the PME triggers through _AEI and _L02
58 methods as would be done for a real GPIO interrupt in ACPI.
60 To compile this driver as a module, choose M here: the module will
61 be called intel_int0002_vgpio.
64 tristate "Intel Oaktrail Platform Extras"
66 depends on ACPI_VIDEO || ACPI_VIDEO=n
67 depends on RFKILL && BACKLIGHT_CLASS_DEVICE && ACPI
69 Intel Oaktrail platform need this driver to provide interfaces to
70 enable/disable the Camera, WiFi, BT etc. devices. If in doubt, say Y
71 here; it will only load on supported platforms.
73 config INTEL_BXTWC_PMIC_TMU
74 tristate "Intel Broxton Whiskey Cove TMU Driver"
75 depends on INTEL_SOC_PMIC_BXTWC
76 depends on MFD_INTEL_PMC_BXT
79 Select this driver to use Intel Broxton Whiskey Cove PMIC TMU feature.
80 This driver enables the alarm wakeup functionality in the TMU unit of
83 config INTEL_CHTDC_TI_PWRBTN
84 tristate "Intel Cherry Trail Dollar Cove TI power button driver"
85 depends on INTEL_SOC_PMIC_CHTDC_TI
88 This option adds a power button driver for Dollar Cove TI
89 PMIC on Intel Cherry Trail devices.
91 To compile this driver as a module, choose M here: the module
92 will be called intel_chtdc_ti_pwrbtn.
94 config INTEL_CHTWC_INT33FE
95 tristate "Intel Cherry Trail Whiskey Cove ACPI INT33FE Driver"
96 depends on X86 && ACPI && I2C && REGULATOR
97 depends on CHARGER_BQ24190=y || (CHARGER_BQ24190=m && m)
98 depends on USB_ROLES_INTEL_XHCI=y || (USB_ROLES_INTEL_XHCI=m && m)
99 depends on TYPEC_MUX_PI3USB30532=y || (TYPEC_MUX_PI3USB30532=m && m)
101 This driver add support for the Intel Cherry Trail Whiskey Cove
102 INT33FE ACPI device found on the GPD win and the GPD pocket.
104 The INT33FE ACPI device on these mini laptops contains I2cSerialBusV2
105 resources for a MAX17042 Fuel Gauge, FUSB302 USB Type-C Controller
106 and PI3USB30532 USB switch.
107 This driver instantiates i2c-clients for these, so that standard
108 i2c drivers for these chips can bind to the them.
110 If you enable this driver it is advised to also select
111 CONFIG_TYPEC_FUSB302=m, CONFIG_TYPEC_MUX_PI3USB30532=m and
112 CONFIG_BATTERY_MAX17042=m.
114 config INTEL_ISHTP_ECLITE
115 tristate "Intel ISHTP eclite controller Driver"
116 depends on INTEL_ISH_HID
119 This driver is for accessing the PSE (Programmable Service Engine) -
120 an Embedded Controller like IP - using ISHTP (Integrated Sensor Hub
121 Transport Protocol) to get battery, thermal and UCSI (USB Type-C
122 Connector System Software Interface) related data from the platform.
123 Users who don't want to use discrete Embedded Controller on Intel's
124 Elkhartlake platform can leverage this integrated solution of
125 ECLite which is part of PSE subsystem.
127 To compile this driver as a module, choose M here: the module
128 will be called intel_ishtp_eclite.
130 config INTEL_MRFLD_PWRBTN
131 tristate "Intel Merrifield Basin Cove power button driver"
132 depends on INTEL_SOC_PMIC_MRFLD
135 This option adds a power button driver for Basin Cove PMIC
136 on Intel Merrifield devices.
138 To compile this driver as a module, choose M here: the module
139 will be called intel_mrfld_pwrbtn.
141 config INTEL_PUNIT_IPC
142 tristate "Intel P-Unit IPC Driver"
144 This driver provides support for Intel P-Unit Mailbox IPC mechanism,
145 which is used to bridge the communications between kernel and P-Unit.
148 tristate "Intel Rapid Start Technology Driver"
151 This driver provides support for modifying parameters on systems
152 equipped with Intel's Rapid Start Technology. When put in an ACPI
153 sleep state, these devices will wake after either a configured
154 timeout or when the system battery reaches a critical state,
155 automatically copying memory contents to disk. On resume, the
156 firmware will copy the memory contents back to RAM and resume the OS
160 tristate "Intel On Demand (Software Defined Silicon) Driver"
161 depends on INTEL_VSEC
164 This driver enables access to the Intel On Demand (formerly Software
165 Defined Silicon) interface used to provision silicon features with an
166 authentication certificate and capability license.
168 To compile this driver as a module, choose M here: the module will
169 be called intel_sdsi.
171 config INTEL_SMARTCONNECT
172 tristate "Intel Smart Connect disabling driver"
175 Intel Smart Connect is a technology intended to permit devices to
176 update state by resuming for a short period of time at regular
177 intervals. If a user enables this functionality under Windows and
178 then reboots into Linux, the system may remain configured to resume
179 on suspend. In the absence of any userspace to support it, the system
180 will then remain awake until something triggers another suspend.
182 This driver checks to determine whether the device has Intel Smart
183 Connect enabled, and if so disables it.
185 config INTEL_TURBO_MAX_3
186 bool "Intel Turbo Boost Max Technology 3.0 enumeration driver"
187 depends on X86_64 && SCHED_MC_PRIO
189 This driver reads maximum performance ratio of each CPU and set up
190 the scheduler priority metrics. In this way scheduler can prefer
191 CPU with higher performance to schedule tasks.
193 This driver is only required when the system is not using Hardware
194 P-States (HWP). In HWP mode, priority can be read from ACPI tables.
197 tristate "Intel Vendor Specific Extended Capabilities Driver"
201 Adds support for feature drivers exposed using Intel PCIe VSEC and
204 To compile this driver as a module, choose M here: the module will
205 be called intel_vsec.
