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. If in doubt, say Y 82 here; it will only load on supported platforms. 83 84config INTEL_BXTWC_PMIC_TMU 85 tristate "Intel Broxton Whiskey Cove TMU Driver" 86 depends on INTEL_SOC_PMIC_BXTWC 87 depends on MFD_INTEL_PMC_BXT 88 select REGMAP 89 help 90 Select this driver to use Intel Broxton Whiskey Cove PMIC TMU feature. 91 This driver enables the alarm wakeup functionality in the TMU unit of 92 Whiskey Cove PMIC. 93 94config INTEL_CHTDC_TI_PWRBTN 95 tristate "Intel Cherry Trail Dollar Cove TI power button driver" 96 depends on INTEL_SOC_PMIC_CHTDC_TI 97 depends on INPUT 98 help 99 This option adds a power button driver for Dollar Cove TI 100 PMIC on Intel Cherry Trail devices. 101 102 To compile this driver as a module, choose M here: the module 103 will be called intel_chtdc_ti_pwrbtn. 104 105config INTEL_ISHTP_ECLITE 106 tristate "Intel ISHTP eclite controller Driver" 107 depends on INTEL_ISH_HID 108 depends on ACPI 109 help 110 This driver is for accessing the PSE (Programmable Service Engine) - 111 an Embedded Controller like IP - using ISHTP (Integrated Sensor Hub 112 Transport Protocol) to get battery, thermal and UCSI (USB Type-C 113 Connector System Software Interface) related data from the platform. 114 Users who don't want to use discrete Embedded Controller on Intel's 115 Elkhartlake platform can leverage this integrated solution of 116 ECLite which is part of PSE subsystem. 117 118 To compile this driver as a module, choose M here: the module 119 will be called intel_ishtp_eclite. 120 121config INTEL_MRFLD_PWRBTN 122 tristate "Intel Merrifield Basin Cove power button driver" 123 depends on INTEL_SOC_PMIC_MRFLD 124 depends on INPUT 125 help 126 This option adds a power button driver for Basin Cove PMIC 127 on Intel Merrifield devices. 128 129 To compile this driver as a module, choose M here: the module 130 will be called intel_mrfld_pwrbtn. 131 132config INTEL_PUNIT_IPC 133 tristate "Intel P-Unit IPC Driver" 134 help 135 This driver provides support for Intel P-Unit Mailbox IPC mechanism, 136 which is used to bridge the communications between kernel and P-Unit. 137 138config INTEL_RST 139 tristate "Intel Rapid Start Technology Driver" 140 depends on ACPI 141 help 142 This driver provides support for modifying parameters on systems 143 equipped with Intel's Rapid Start Technology. When put in an ACPI 144 sleep state, these devices will wake after either a configured 145 timeout or when the system battery reaches a critical state, 146 automatically copying memory contents to disk. On resume, the 147 firmware will copy the memory contents back to RAM and resume the OS 148 as usual. 149 150config INTEL_SMARTCONNECT 151 tristate "Intel Smart Connect disabling driver" 152 depends on ACPI 153 help 154 Intel Smart Connect is a technology intended to permit devices to 155 update state by resuming for a short period of time at regular 156 intervals. If a user enables this functionality under Windows and 157 then reboots into Linux, the system may remain configured to resume 158 on suspend. In the absence of any userspace to support it, the system 159 will then remain awake until something triggers another suspend. 160 161 This driver checks to determine whether the device has Intel Smart 162 Connect enabled, and if so disables it. 163 164config INTEL_TURBO_MAX_3 165 bool "Intel Turbo Boost Max Technology 3.0 enumeration driver" 166 depends on X86_64 && SCHED_MC_PRIO 167 help 168 This driver reads maximum performance ratio of each CPU and set up 169 the scheduler priority metrics. In this way scheduler can prefer 170 CPU with higher performance to schedule tasks. 171 172 This driver is only required when the system is not using Hardware 173 P-States (HWP). In HWP mode, priority can be read from ACPI tables. 174 175config INTEL_UNCORE_FREQ_CONTROL 176 tristate "Intel Uncore frequency control driver" 177 depends on X86_64 178 help 179 This driver allows control of Uncore frequency limits on 180 supported server platforms. 181 182 Uncore frequency controls RING/LLC (last-level cache) clocks. 183 184 To compile this driver as a module, choose M here: the module 185 will be called intel-uncore-frequency. 186 187config INTEL_VSEC 188 tristate "Intel Vendor Specific Extended Capabilities Driver" 189 depends on PCI 190 select AUXILIARY_BUS 191 help 192 Adds support for feature drivers exposed using Intel PCIe VSEC and 193 DVSEC. 194 195 To compile this driver as a module, choose M here: the module will 196 be called intel_vsec. 197 198endif # X86_PLATFORM_DRIVERS_INTEL 199
