Hello,
I cannot resume from S3 sleep in Dom0. I'm running on Xen 4.2.1 with Dom0
3.6.11-1-ARCH linux. The laptop is lenovo T400 with Intel Core2 Duo
processor.
I've found in one of the previous threads that the problem might be caused
by lacking the acpi-cpufreq module in Dom0. However, when I try to load it,
I get 'no such device' error. This error is present on both, Domain0 based
cpufreq as well as Hypervisor based cpufreq power management.
I suspect this is a Xen related issue.
Thank you,
Milan

I'm not sure what Arch linux uses for a kernel, as I'm not terribly
familiar with the distro.
That said, a number of things are needed to get this to work, that are
not accepted upstream.
1. You'll need one of Konrad's acpi-s3 branches, or the patches from
the tip of those branches:
http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git;a=shortlog;h=refs/heads/devel/acpi-s3.v9
2. Apply the attached patches in the following order:
fix-dmar-zap-reinstate
fix-suspend-scheduler-v2
fix-suspend-scheduler-revert-affinity-part
s3-timerirq
All of these fixes have been proposed to the xen-devel list, but have
not yet been accepted, for one reason, or another.
I've CC'ed Konrad, and Tomasz who authored some of the things
mentioned above, and Jan Beulich who has been commenting on the
validity / correctness of these changes.

And I don't think comments on them have seen follow-ups.

I guess it's worth bringing this up again;
s3-timerirq: this was empirical hack which for some reason is needed on
stable 4.2 we use, but not on latest unstable, didn't really investigate
further since it appeared fixed later on anyway..
fix-suspend-scheduler/revert-affinity: the big objection here was the
part which reverts one of the hunks in Keir's commit. I tried for quite
few days to find a working fix which does not do this revert using
posted suggestions, but was not succesfull:
- there was a crash in xen scheduler, which was fixable using your
suggestion of masking softirqs during s3 (ugly)
- there was also a crash in xen acpi cpufreq driver, which was
similarily fixable using a bandaid s3 condition (ugly)
- unfortunately this turned out to not be all, xen did not crash anymore
at this point but dom0 kernel did around the time it enables cpus, in
multiple places: at this point I didn't have a good explanation for it,
my opinion of aggravating hunk was rather low, so I uttered a hearty
curse and stuck a revert into private patchqueue.
The dom0 kernel crashes were as follows:

Hm, that is suspect. There should not be any cpuidle_register? Perhaps
you are .. ah yes, you are hitting a bug that should be in the stable
tree fix.
Here is the git commit b88a634a903d9670aa5f2f785aa890628ce0dece and

[-- Attachment #1.1: Type: text/plain, Size: 16372 bytes --]
Thank you for your help guys. I tried to apply those patches, but I didn't
succeed.
Konrard's acpi-s3 worked (in sence I didn't get error while patching), but
the patches from Ben not. Arch linux is using pretty much vanilla kernel
with only 3 patches applied(upstream patch, default console loglevel patch
and fat issue patch), and it seems I'm missing a whole lot of things there.
For instance, the 'fix-dmar-zap-reinstate.txt' requires /xen/drivers/
folder, but in my kernel source it is missing (there is xen, but no
drivers).
I'm not familiar with custom kernel building (this was my first time), but
I would say I'm missing some xen patches that should be applied priror to
those of Ben.
Could you please give me a hint on how can I proceed or what kernel did you
use?
Thank you very much for your time.

Milan, these three patches from Ben are against xen, not linux kernel -
so you have to build patched xen from sources.

Thanks Konrad. I've tried your patches, and whilst I have not seen this
crash in cpuidle_register anymore, the others are still present (in
build_schedule_domains for example).
I've stumbled on a bit of interesting info - using dom0_vcpus_pin on xen
commandline stops both the xen scheduler and dom0 kernel crashing and
all works fine - made dozens of succesfull s3 attempts. Was wondering if
you guys had any thoughts on this? Is the dom0 kernel even supposed to
cope during s3 in non dom0 vcpu pin case?

That looks familiar too. I think it got fixed in the upstream kernel
and it was a generic bug - but I can't recall which commit it was.

No that is something new. Is this only an issue on Intel boxes but not AMD?

I apologize for the patching confusion. I applied Konrad's acpi-s3 patch to
linux 3.7.5-1 and Ben's Xen patches to Xen 4.2.1-3 stable. I've also put
dom0_vcpus_pin to xen kernel line in bootloader but still I cannot modprobe
acpi_cpufreq and S3 sleep resume still not working.
How can I debug it?
Thanks.

I think it was primarily reproducible on sandybridge intels whilst being
hard/impossible to repro on Ivy Bridge - and sorry - don't have an AMD
box to make a test. It might just go away with newer kernel though, I
think we're in the process of updating to 3.8 (previous tests were on
3.2) so will be worth trying on that.

The module is xen-acpi-processor and you should see whether it works by
running 'xenpm get-cpufreq-para'. If you get values then it worked.

xen-acpi-processor module is loaded and xenpm get-cpufreq-para seems to be
ok. Unfortunately resume from S3 still doesn't work.

So then the process of elimination starts. Try doing it without having Xorg or any
KMS drivers running (so text-console). Then also try without serial output.
And also as somebody suggested with dom0_pin_vcpus arguments.

Without, you mean? Iirc Ben's findings suggested that there are
problems when this option is used.

Yes, this was the reason for some of the scheduler changes introduced
by system_state in the original patches I attached.

Still not working. I tried it only using tty without X, without KMS
drivers(nomodeset in kernel parameters and with module i915 removed) and
with and without dom0_pin_vcpus parameter. No success.
Strangely, I remember it used to work with some earlier version of kernel
and/or Xen (unfortunately I can't remember which combination of Xen and
kernel it was)
