This option alone does not add any kernel code. 13 14 If you say N, all options in this submenu will be skipped 15 and disabled. 16 17if X86_PLATFORM_DRIVERS_INTEL 18 19source "drivers/platform/x86/intel/atomisp2/Kconfig" 20source "drivers/platform/x86/intel/int1092/Kconfig" 21source "drivers/platform/x86/intel/int33fe/Kconfig" 22source "drivers/platform/x86/intel/int3472/Kconfig" 23source "drivers/platform/x86/intel/pmc/Kconfig" 24source "drivers/platform/x86/intel/pmt/Kconfig" 25source "drivers/platform/x86/intel/speed_select_if/Kconfig" 26source "drivers/platform/x86/intel/telemetry/Kconfig" 27source "drivers/platform/x86/intel/wmi/Kconfig" 28 29config INTEL_HID_EVENT 30 tristate "Intel HID Event" 31 depends on ACPI 32 depends on INPUT 33 depends on I2C 34 select INPUT_SPARSEKMAP 35 help 36 This driver provides support for the Intel HID Event hotkey interface. 37 Some laptops require this driver for hotkey support. 38 39 To compile this driver as a module, choose M here: the module will 40 be called intel_hid. 41 42config INTEL_VBTN 43 tristate "Intel Virtual Button" 44 depends on ACPI 45 depends on INPUT 46 depends on I2C 47 select INPUT_SPARSEKMAP 48 help 49 This driver provides support for the Intel Virtual Button interface. 50 Some laptops require this driver for power button support. 51 52 To compile this driver as a module, choose M here: the module will 53 be called intel_vbtn. 54 55config INTEL_INT0002_VGPIO 56 tristate "Intel ACPI INT0002 Virtual GPIO driver" 57 depends on GPIOLIB && ACPI && PM_SLEEP 58 select GPIOLIB_IRQCHIP 59 help 60 Some peripherals on Bay Trail and Cherry Trail platforms signal a 61 Power Management Event (PME) to the Power Management Controller (PMC) 62 to wakeup the system. When this happens software needs to explicitly 63 clear the PME bus 0 status bit in the GPE0a_STS register to avoid an 64 IRQ storm on IRQ 9. 65 66 This is modelled in ACPI through the INT0002 ACPI device, which is 67 called a "Virtual GPIO controller" in ACPI because it defines the 68 event handler to call when the PME triggers through _AEI and _L02 69 methods as would be done for a real GPIO interrupt in ACPI. 70 71 To compile this driver as a module, choose M here: the module will 72 be called intel_int0002_vgpio. 73 74config INTEL_OAKTRAIL 75 tristate "Intel Oaktrail Platform Extras" 76 depends on ACPI 77 depends on ACPI_VIDEO || ACPI_VIDEO=n 78 depends on RFKILL && BACKLIGHT_CLASS_DEVICE && ACPI 79 help 80 Intel Oaktrail platform need this driver to provide interfaces to 81 enable/disable the Camera, WiFi, BT etc. devices.

When put in an ACPI 128 sleep state, these devices will wake after either a configured 129 timeout or when the system battery reaches a critical state, 130 automatically copying memory contents to disk. On resume, the 131 firmware will copy the memory contents back to RAM and resume the OS 132 as usual. 133 134config INTEL_SMARTCONNECT 135 tristate "Intel Smart Connect disabling driver" 136 depends on ACPI 137 help 138 Intel Smart Connect is a technology intended to permit devices to 139 update state by resuming for a short period of time at regular 140 intervals. If a user enables this functionality under Windows and 141 then reboots into Linux, the system may remain configured to resume 142 on suspend. In the absence of any userspace to support it, the system 143 will then remain awake until something triggers another suspend. 144 145 This driver checks to determine whether the device has Intel Smart 146 Connect enabled, and if so disables it. 147 148config INTEL_TURBO_MAX_3 149 bool "Intel Turbo Boost Max Technology 3.0 enumeration driver" 150 depends on X86_64 && SCHED_MC_PRIO 151 help 152 This driver reads maximum performance ratio of each CPU and set up 153 the scheduler priority metrics. In this way scheduler can prefer 154 CPU with higher performance to schedule tasks. 155 156 This driver is only required when the system is not using Hardware 157 P-States (HWP). In HWP mode, priority can be read from ACPI tables. 158 159config INTEL_UNCORE_FREQ_CONTROL 160 tristate "Intel Uncore frequency control driver" 161 depends on X86_64 162 help 163 This driver allows control of Uncore frequency limits on 164 supported server platforms. 165 166 Uncore frequency controls RING/LLC (last-level cache) clocks. 167 168 To compile this driver as a module, choose M here: the module 169 will be called intel-uncore-frequency. 170 171endif # X86_PLATFORM_DRIVERS_INTEL 172
