[ANNOUNCE] Userland suspend/hibernation tool v0.8 released
Rafael J. Wysocki
been released. The source code package is available for download at:
http://downloads.sourceforge.net/suspend/suspend-0.8.tar.gz
(changelog and release notes within).
The following utilities are included in the package (among other things):
s2ram
- Wrapper around the kernel's suspend-to-RAM mechanism allowing the user to
perform some graphics adapter manipulations from the user land before
suspending and after resuming that may help to bring the graphics (and the
entire system) back to life after the resume. Incorporates the functionality
of vbetool and radeontool as well as some tricks of its own. Includes a list
of working hardware configurations along with the appropriate sets of
operations to be performed to resume them successfully.
s2disk
- Saves hibernation images created by the kernel using the /dev/snapshot
special device and its ioctl interface. Supports image compression, image
encryption (in particular, it is possible to use RSA to safely pass the
session key information between s2disk and its resume counterpart)
and splash-based graphical progress meters (bootsplash, splashy and fbsplash
are supported).
s2both
- Saves a hibernation image like s2disk and then suspends the system to RAM
like s2ram, allowing it to either resume from RAM, if the system memory is
still powered, or resume from the hibernation image (still considered as
experimental).
resume
- Loads a hibernation image saved by s2disk/s2both and makes the kernel restore
the system memory state from it using the /dev/snapshot special device and
its ioctl interface. Intended for running from initrd/initramfs images.
