Currently only backlight 775 control is supported by the driver. 776 777config INTEL_RST 778 tristate "Intel Rapid Start Technology Driver" 779 depends on ACPI 780 ---help--- 781 This driver provides support for modifying paramaters on systems 782 equipped with Intel's Rapid Start Technology. When put in an ACPI 783 sleep state, these devices will wake after either a configured 784 timeout or when the system battery reaches a critical state, 785 automatically copying memory contents to disk. On resume, the 786 firmware will copy the memory contents back to RAM and resume the OS 787 as usual. 788 789config INTEL_SMARTCONNECT 790 tristate "Intel Smart Connect disabling driver" 791 depends on ACPI 792 ---help--- 793 Intel Smart Connect is a technology intended to permit devices to 794 update state by resuming for a short period of time at regular 795 intervals. If a user enables this functionality under Windows and 796 then reboots into Linux, the system may remain configured to resume 797 on suspend. In the absence of any userspace to support it, the system 798 will then remain awake until something triggers another suspend. 799 800 This driver checks to determine whether the device has Intel Smart 801 Connect enabled, and if so disables it. 802 803config PVPANIC 804 tristate "pvpanic device support" 805 depends on ACPI 806 ---help--- 807 This driver provides support for the pvpanic device. pvpanic is 808 a paravirtualized device provided by QEMU; it lets a virtual machine 809 (guest) communicate panic events to the host. 810 811endif # X86_PLATFORM_DEVICES 812
