No. For suspend (to RAM) all it needs is s2ram installed. For suspend to disk you need to fix the assumption that /sys/power/disk has 'platform' as a valid option. What's the correct assumption for hibernate? Just accept what is set as default in /sys/power/disk by the kernel and do a simple echo disk /sys/power/state? You can take whichever one you like, but you should first *check* that it *exists* by reading /sys/power/disk and seeing if it's listed in there, and only then try to use it. 'platform' may be necessary on some brain-dead ACPI machines, but it doesn't exist on powerpc. johannes signature.asc Description: This is a digitally signed message part

Just wondering.. Why isn't your patch so suspend via /sys/power/state instead of the PMU ioctl in the upstream kernel yet :) IMHO it would be good to have that interface work on ppc too (It would save us a lot of special casing) Because Paul Mackerras dislikes the freezer which that currently implies. It may go into 2.6.25. Yesterday i did a rebuild/upload of uswsusp on powerpc, so uswsusp is now available and working on ppc (works nicely on my powerbook).. pm-utils still needs a little tweak though, but nothing big. :) johannes signature.asc Description: This is a digitally signed message part

pm-hibernate has no such option and thus breaks. Not sure why s2disk is involved at all? s2disk isn't involved per se, but it can bring your machine in hibernation. It can work as a `back end' in pm-hibernate. Right. That much I understand. I'm not sure we're understanding each other. In my understanding, on a powermac, the interface /sys/power/state was not working for suspend-to-ram. Correct, on a G5 powermac there is no suspend to RAM implemented at all. On a G4 powerbook/powermac suspend to RAM is implemented but not via /sys/power/state. If I read your e-mails to this report it isn't working for hibernation either. Right? /sys/power/state works for hibernation on a G5 powermac, on a G4 powermac/powerbook it also works but is broken when DRI is enabled. Now, for S3 there were some ioctl that had to be used. This is now in the s2ram binary. Yes, for suspend to RAM (there is no S3 on powermacs/powerbooks! stop confusing everybody with ACPI terminology :) ) there are ioctls on /dev/pmu to be used. And now I just reviewed the s2ram sources and indeed, it does implement this. So I guess the whole bug is s2ram isn't installed by default. Are you saying that for S4 we need something similar (eg. some binary that pokes some ioclts?) No. For suspend (to RAM) all it needs is s2ram installed. For suspend to disk you need to fix the assumption that /sys/power/disk has 'platform' as a valid option. johannes signature.asc Description: This is a digitally signed message part

I consider the non-functioning /sys/power/state interface a kernel bug. s2ram and s2disk provide extra features and workarounds for machines where the bare interface doesn't work. It is mostly video-adapter related hacks but in the case of powerpc s2ram it uses some ioctls to get it to suspend to ram. I thought s2disk was also tested and working, but apparently not.
