Currently only backlight 784 control is supported by the driver. 785 786config INTEL_RST 787 tristate "Intel Rapid Start Technology Driver" 788 depends on ACPI 789 ---help--- 790 This driver provides support for modifying paramaters on systems 791 equipped with Intel's Rapid Start Technology. When put in an ACPI 792 sleep state, these devices will wake after either a configured 793 timeout or when the system battery reaches a critical state, 794 automatically copying memory contents to disk. On resume, the 795 firmware will copy the memory contents back to RAM and resume the OS 796 as usual. 797 798config INTEL_SMARTCONNECT 799 tristate "Intel Smart Connect disabling driver" 800 depends on ACPI 801 ---help--- 802 Intel Smart Connect is a technology intended to permit devices to 803 update state by resuming for a short period of time at regular 804 intervals. If a user enables this functionality under Windows and 805 then reboots into Linux, the system may remain configured to resume 806 on suspend. In the absence of any userspace to support it, the system 807 will then remain awake until something triggers another suspend. 808 809 This driver checks to determine whether the device has Intel Smart 810 Connect enabled, and if so disables it. 811 812config PVPANIC 813 tristate "pvpanic device support" 814 depends on ACPI 815 ---help--- 816 This driver provides support for the pvpanic device. pvpanic is 817 a paravirtualized device provided by QEMU; it lets a virtual machine 818 (guest) communicate panic events to the host. 819 820endif # X86_PLATFORM_DEVICES 821
