Booting - new idea?
|
|
| Arto Inkala 2006-06-29, 7:39 am |
| Hello,
booting takes usually tens of seconds and it's based on starting and
running different programs. Is it possible to skip this part of booting?
Particularly, is it possible to save the state of hardware and memories
during shutdown and upload them during boot time? I suppose, this would
minimize booting time, if it is technically possible to realize and
start programs this way?
If there is already this kind of project going on, I'd like to hear
about it.
Regards,
Arto

You mean suspend to disk ?

And works properly in Debian since what? Weeks? Months?_:-)

It doesn't really work properly anywhere, does it? :-P

Has worked properly here very well with suspend2, which isn't in the
stock kernel unfortunately.
Now it also works very well here with vanilla kernel 2.6.17 and the
debian package for uswsusp which I've packaged.
You can try them out if you like (you need a 2.6.17 kernel),
http://www.famdijkstra.org/~tdykstra/debian/uswsusp
But I hope they'll get uploaded very soon.

Oh, ok but my comment was about our kernel really.

I'll take a look thanks, but did you see the recent discussion in lkml ? Linus
came up with a patch to definitely solve some of the problems with the suspend
model. AFAIK, it's not yet into his tree or mm, but i hope to see the
changes merged in time for 2.6.18, really cool stuff there. I think
you can read a summary by Greg at lwn.

Has worked properly here very well with whatever is in the debian
kernel, since 2.6.15 at least.

Well Mike, maybe very well for you not for many users and some kernel
developers[0] agreed. Btw, Greg wrote an article for lwn (major
suspend changes),
read it there if you're subscribed. Really interesting content that shows the
current problems with the kernel implementation (up to 2.6.17) that should
be solved soon, since Linus came up with a interesting patch.

Hum, this is about suspend to ram, not suspend to disk. Though suspend
to ram has been working almost flawlessly for me since 2.6.9 or 2.6.10.
(sometimes it freezes at wakeup time). I don't really care if the kernel
developpers say it's badly done. It just works. That's all I'm asking.
