I think various linux-PM folk might be interested in this, not just ARM and OMAP folk. I've not looked at it much yet; note that it's using a 2.6.11 kernel (vs the latest OMAP kernel) and relies on updated boot loader firmware. - Dave p.s. OSK is a small OMAP1 development board: http://tree.celinuxforum.org/CelfPubWiki/OSK ---------- Forwarded Message ---------- Subject: [RFC] SnapshotBoot for OSK5912 Date: Tuesday 11 July 2006 4:03 am From: Hiroki Kaminaga <kaminaga at sm.sony.co.jp> To: linux-arm-kernel at lists.arm.linux.org.uk Hi, I made a page describing snapshot boot. Patch and instructions are available here: http://tree.celinuxforum.org/CelfPubWiki/SuspendToDiskForARM Snapshot boot is essentially a resume-from-disk operation, which is a system resume from a semi-permanent snapshot image stored on flash memory for OSK5912, that restores the machine to a known running state. As opposed to a standard resume operation, a snapshot image is made only once, stored on flash memory, and same image is used repeatedly, every time the system is powered on. The purpose of this is to achieve faster startup time of linux on OSK5912. It is still OSK5912 specific, but would like to hear comments.
