When this happens software needs to explicitly 50 clear the PME bus 0 status bit in the GPE0a_STS register to avoid an 51 IRQ storm on IRQ 9. 52 53 This is modelled in ACPI through the INT0002 ACPI device, which is 54 called a "Virtual GPIO controller" in ACPI because it defines the 55 event handler to call when the PME triggers through _AEI and _L02 56 methods as would be done for a real GPIO interrupt in ACPI. 57 58 To compile this driver as a module, choose M here: the module will 59 be called intel_int0002_vgpio. 60 61config INTEL_OAKTRAIL 62 tristate "Intel Oaktrail Platform Extras" 63 depends on ACPI 64 depends on ACPI_VIDEO || ACPI_VIDEO=n 65 depends on RFKILL && BACKLIGHT_CLASS_DEVICE && ACPI 66 help 67 Intel Oaktrail platform need this driver to provide interfaces to 68 enable/disable the Camera, WiFi, BT etc. devices. If in doubt, say Y 69 here; it will only load on supported platforms. 70 71config INTEL_BXTWC_PMIC_TMU 72 tristate "Intel Broxton Whiskey Cove TMU Driver" 73 depends on INTEL_SOC_PMIC_BXTWC 74 depends on MFD_INTEL_PMC_BXT 75 select REGMAP 76 help 77 Select this driver to use Intel Broxton Whiskey Cove PMIC TMU feature. 78 This driver enables the alarm wakeup functionality in the TMU unit of 79 Whiskey Cove PMIC. 80 81config INTEL_CHTDC_TI_PWRBTN 82 tristate "Intel Cherry Trail Dollar Cove TI power button driver" 83 depends on INTEL_SOC_PMIC_CHTDC_TI 84 depends on INPUT 85 help 86 This option adds a power button driver for Dollar Cove TI 87 PMIC on Intel Cherry Trail devices. 88 89 To compile this driver as a module, choose M here: the module 90 will be called intel_chtdc_ti_pwrbtn. 91 92config INTEL_ISHTP_ECLITE 93 tristate "Intel ISHTP eclite controller Driver" 94 depends on INTEL_ISH_HID 95 depends on ACPI 96 help 97 This driver is for accessing the PSE (Programmable Service Engine) - 98 an Embedded Controller like IP - using ISHTP (Integrated Sensor Hub 99 Transport Protocol) to get battery, thermal and UCSI (USB Type-C 100 Connector System Software Interface) related data from the platform. 101 Users who don't want to use discrete Embedded Controller on Intel's 102 Elkhartlake platform can leverage this integrated solution of 103 ECLite which is part of PSE subsystem. 104 105 To compile this driver as a module, choose M here: the module 106 will be called intel_ishtp_eclite. 107 108config INTEL_MRFLD_PWRBTN 109 tristate "Intel Merrifield Basin Cove power button driver" 110 depends on INTEL_SOC_PMIC_MRFLD 111 depends on INPUT 112 help 113 This option adds a power button driver for Basin Cove PMIC 114 on Intel Merrifield devices. 115 116 To compile this driver as a module, choose M here: the module 117 will be called intel_mrfld_pwrbtn. 118 119config INTEL_PUNIT_IPC 120 tristate "Intel P-Unit IPC Driver" 121 help 122 This driver provides support for Intel P-Unit Mailbox IPC mechanism, 123 which is used to bridge the communications between kernel and P-Unit. 124 125config INTEL_RST 126 tristate "Intel Rapid Start Technology Driver" 127 depends on ACPI 128 help 129 This driver provides support for modifying parameters on systems 130 equipped with Intel's Rapid Start Technology. When put in an ACPI 131 sleep state, these devices will wake after either a configured 132 timeout or when the system battery reaches a critical state, 133 automatically copying memory contents to disk. On resume, the 134 firmware will copy the memory contents back to RAM and resume the OS 135 as usual. 136 137config INTEL_SMARTCONNECT 138 tristate "Intel Smart Connect disabling driver" 139 depends on ACPI 140 help 141 Intel Smart Connect is a technology intended to permit devices to 142 update state by resuming for a short period of time at regular 143 intervals. If a user enables this functionality under Windows and 144 then reboots into Linux, the system may remain configured to resume 145 on suspend. In the absence of any userspace to support it, the system 146 will then remain awake until something triggers another suspend. 147 148 This driver checks to determine whether the device has Intel Smart 149 Connect enabled, and if so disables it. 150 151config INTEL_TURBO_MAX_3 152 bool "Intel Turbo Boost Max Technology 3.0 enumeration driver" 153 depends on X86_64 && SCHED_MC_PRIO 154 help 155 This driver reads maximum performance ratio of each CPU and set up 156 the scheduler priority metrics. In this way scheduler can prefer 157 CPU with higher performance to schedule tasks. 158 159 This driver is only required when the system is not using Hardware 160 P-States (HWP). In HWP mode, priority can be read from ACPI tables. 161 162config INTEL_UNCORE_FREQ_CONTROL 163 tristate "Intel Uncore frequency control driver" 164 depends on X86_64 165 help 166 This driver allows control of Uncore frequency limits on 167 supported server platforms. 168 169 Uncore frequency controls RING/LLC (last-level cache) clocks. 170 171 To compile this driver as a module, choose M here: the module 172 will be called intel-uncore-frequency. 173 174config INTEL_VSEC 175 tristate "Intel Vendor Specific Extended Capabilities Driver" 176 depends on PCI 177 select AUXILIARY_BUS 178 help 179 Adds support for feature drivers exposed using Intel PCIe VSEC and 180 DVSEC. 181 182 To compile this driver as a module, choose M here: the module will 183 be called intel_vsec. 184
