From 34a956db3774e8cba3f6b52aa9c1d67cf9a496fe Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Tue, 2 Jul 2013 18:41:03 -0400 Subject: Add support driver for Intel Rapid Start Technology Intel Rapid Start Technology is a firmware-based suspend-to-disk implementation. Once placed in S3, the device will wake once either a timeout elapses or the battery reaches a critical level. It will then resume to the firmware and copy the contents of RAM to a specialised partition, and then power off the machine. If the user turns the machine back on the firmware will copy the contents of the partition back to RAM and then resume from S3 as normal. This driver provides an interface for configuring the wakeup events and timeout. It still requires firmware support and an appropriate suspend partition.
