[arch-general] S3-level ACPI suspend
Hi, I've had some nice experiences with Windows(XP)'s suspend functionality, and it seems to work on all machines I've worked with. and the other day I just had a successful resume on my machine with "s2ram -f -m -p", but it takes like a minute for it to fully recover to a terminal (tty/1). (ps: my computer is a desktop with AMD RS780 chipset, which isn't supported by KMS yet) Unlike Windows ones, which only take like 3-5 seconds to wake up, linux takes much longer, I don't know if this is common... My question is: What's the average resume time of yours, and is it possible to be any faster ?

My somewhat slow laptop (Pentium M 1.60Ghz, 512MB RAM) resumes fully from in about 5 seconds (yes, on Arch Linux). Your figure seems very high at one full minute. Did you check the logs? Maybe it is also loading some stuff from the swap file which it will do in case it couldn't fit it all in RAM.

It takes something like 10 seconds or so for me. I noticed that you are
using s2ram, have you tried to use pm-utils
(http://wiki.archlinux.org/index.php/Pm-utils)?

My netbook (Intel Atom 1.6Ghz, 1GB ram) comes up from suspend-to-ram in about 3 seconds. I use pmutils to suspend. -- Alexander Lam

So it's just me then. I've read the wiki about Pm-utils, but it isn't very thorough though. Trying it anyway.
I think I nailed it. With luck, I was able to resume the computer with "s2ram -f -a 1", even it's within Xorg. But it still takes a long time to resume, then I found out about my drives hooked on an old IDE extension card stopped working. So I removed the module "pata_hpt37x", and... Wala, 11 seconds ! Now it's only issue is to automated this umount+rmmod and modprobe+mount thing...

Using pm-utils it is quite easy to do such things:

There must be something similar for s2ram. According to the wiki
(http://wiki.archlinux.org/index.php/Suspend_to_RAM) the file
"hibernate.conf" should make it possible to say which modules need to be
unloaded.

There is no need. Pm-utils is a frame-work which supports uswsusp (s2ram/s2disk), tuxonice and kernel (which is default). So user can just setup /etc/pm/config.d/config like so: SLEEP_MODULE="uswsusp" SUSPEND_MODULES="pata_hpt37x" Although uswsusp supports quirks and maintains a whitelist, it's better to include pm-utils in the story since it is a standard. It has quirks, reads HAL whitelist, and exposes a nice frame-work for writing your own hooks. -- Adrian C.

Does it support the hibernate-script feature "UnloadAllModules" ? I find it necessary for suspend to ram -- damjan

Not likely, at least not by SUSPEND_MODULES, modules hook calls a function modunload which runs rmmod and knows how to handle dependant modules. Modules hook is called 75modules... if a hook with the same name is found in /etc/pm it takes precedance. Maybe someone implemented that in a personal hook, but probably not when hibernate-script does the work. -- Adrian C.
