When this happens software needs to explicitly 52 clear the PME bus 0 status bit in the GPE0a_STS register to avoid an 53 IRQ storm on IRQ 9. 54 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. 59 60 To compile this driver as a module, choose M here: the module will 61 be called intel_int0002_vgpio. 62 63config INTEL_OAKTRAIL 64 tristate "Intel Oaktrail Platform Extras" 65 depends on ACPI 66 depends on ACPI_VIDEO || ACPI_VIDEO=n 67 depends on RFKILL && BACKLIGHT_CLASS_DEVICE && ACPI 68 help 69 Intel Oaktrail platform need this driver to provide interfaces to 70 enable/disable the Camera, WiFi, BT etc. devices.

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 157 as usual. 158 159config INTEL_SDSI 160 tristate "Intel On Demand (Software Defined Silicon) Driver" 161 depends on INTEL_VSEC 162 depends on X86_64 163 help 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. 167 168 To compile this driver as a module, choose M here: the module will 169 be called intel_sdsi. 170 171config INTEL_SMARTCONNECT 172 tristate "Intel Smart Connect disabling driver" 173 depends on ACPI 174 help 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.

In the absence of any userspace to support it, the system 180 will then remain awake until something triggers another suspend. 181 182 This driver checks to determine whether the device has Intel Smart 183 Connect enabled, and if so disables it. 184 185config INTEL_TURBO_MAX_3 186 bool "Intel Turbo Boost Max Technology 3.0 enumeration driver" 187 depends on X86_64 && SCHED_MC_PRIO 188 help 189 This driver reads maximum performance ratio of each CPU and set up 190 the scheduler priority metrics.
