When this happens software needs to explicitly 51 clear the PME bus 0 status bit in the GPE0a_STS register to avoid an 52 IRQ storm on IRQ 9. 53 54 This is modelled in ACPI through the INT0002 ACPI device, which is 55 called a "Virtual GPIO controller" in ACPI because it defines the 56 event handler to call when the PME triggers through _AEI and _L02 57 methods as would be done for a real GPIO interrupt in ACPI. 58 59 To compile this driver as a module, choose M here: the module will 60 be called intel_int0002_vgpio. 61 62config INTEL_OAKTRAIL 63 tristate "Intel Oaktrail Platform Extras" 64 depends on ACPI 65 depends on ACPI_VIDEO || ACPI_VIDEO=n 66 depends on RFKILL && BACKLIGHT_CLASS_DEVICE && ACPI 67 help 68 Intel Oaktrail platform need this driver to provide interfaces to 69 enable/disable the Camera, WiFi, BT etc. devices.

When put in an ACPI 152 sleep state, these devices will wake after either a configured 153 timeout or when the system battery reaches a critical state, 154 automatically copying memory contents to disk. On resume, the 155 firmware will copy the memory contents back to RAM and resume the OS 156 as usual. 157 158config INTEL_SDSI 159 tristate "Intel Software Defined Silicon Driver" 160 depends on INTEL_VSEC 161 depends on X86_64 162 help 163 This driver enables access to the Intel Software Defined Silicon 164 interface used to provision silicon features with an authentication 165 certificate and capability license. 166 167 To compile this driver as a module, choose M here: the module will 168 be called intel_sdsi. 169 170config INTEL_SMARTCONNECT 171 tristate "Intel Smart Connect disabling driver" 172 depends on ACPI 173 help 174 Intel Smart Connect is a technology intended to permit devices to 175 update state by resuming for a short period of time at regular 176 intervals. If a user enables this functionality under Windows and 177 then reboots into Linux, the system may remain configured to resume 178 on suspend. In the absence of any userspace to support it, the system 179 will then remain awake until something triggers another suspend. 180 181 This driver checks to determine whether the device has Intel Smart 182 Connect enabled, and if so disables it. 183 184config INTEL_TURBO_MAX_3 185 bool "Intel Turbo Boost Max Technology 3.0 enumeration driver" 186 depends on X86_64 && SCHED_MC_PRIO 187 help 188 This driver reads maximum performance ratio of each CPU and set up 189 the scheduler priority metrics.
