Attached, now Lee or anyone can start hacking.
Suspend-to-disk HOWTO
~~~~~~~~~~~~~~~~~~~~
Copyright (C) 2006 Pavel Machek <[email protected]>
You'll need /dev/snapshot for these to work:
crw-r--r-- 1 root root 10, 231 Jan 13 21:21 /dev/snapshot
Then compile userspace tools in usual way. You'll need an -mm kernel
for now. To suspend-to-disk, run
./suspend /dev/<your_swap_partition>
. (There should be just one, for now.) Suspend is easy, resume is
slightly harder. Resume application has to be ran without any
filesystems mounted rw, and without any journalling filesystems
mounted at all, preferably from initrd (but read-only ext2 should do
the trick, too). Resume is then as easy as running
./resume /dev/<your_swap_partition>
. You probably want to create script that attempts to resume with
above command, and if that fails, fall back to init.
