From 9b238205ba5d79a8a242d7a5ddb82b89e4dc4e48 Mon Sep 17 00:00:00 2001 From: Luca Tettamanti Date: Thu, 23 Mar 2006 03:00:09 -0800 Subject: [PATCH] swsusp: add s2ram ioctl to userland interface Add the SNAPSHOT_S2RAM ioctl to the snapshot device. This ioctl allows a userland application to make the system (previously frozen with the SNAPSHOT_FREE ioctl) enter the S3 state without freezing processes and disabling nonboot CPUs for the second time. This will allow us to implement the suspend-to-disk-and-RAM (STDR) functionality in the userland suspend tools. Signed-off-by: Luca Tettamanti Signed-off-by: Rafael J.
