Host S3

Host S3

[scorbin]

What is the state of host suspend to ram?  I noticed that this
functionality was put into 3.2 with fixes in 3.3.  I also saw something
recently that indicates there might be a separate tree where suspend/S3
is being developed/enhanced?

I did try Xen3.3/Ubuntu8.04 and did not get host S3 to resume properly.
Straight Ubuntu 8.04 suspends/resumes fine.

It does work on many systems, but it hasn't had very wide testing as yet.

What is the hardware it didn't work for you?

Re: Host S3

I tried it on a Dell, Lenovo and 2 HPs.  Upon further investigation it
turns out the systems are resuming but the video card is not
re-initialized.  It's strange because I can use the same procedure for
Linux without Xen and the video resumes properly.

Searching the web I found suspend.sf.net.  Is this what people are using
to do the video restore?

Re: Host S3

[scorbin]

It looks like suspend.sf.net will not work.  The s2ram utility
requires /proc/sys/kernel/acpi_sleep_flags which does not exist in the
Xen patched Linux kernel.  It is removed via CONFIG_ACPI_PV_SLEEP.

So how are people using dom0 suspend/resume?  Any sample scripts/code?
Simply doing 'echo mem > /sys/power/state' does not restore the graphics
card.  I also tried a script I found on the web that effectively does:

# dump current data from the video card to the temporary file
cat /proc/bus/pci/$ID > $TMP_FILE

# suspend
echo -n mem > /sys/power/state

# restore video card data from the temporary file on resume
cat $TMP_FILE > /proc/bus/pci/$ID

with the same result that bare Linux works but booting with Xen does not
restore the video card.

RE: Host S3

[Kamala Narasimhan]

You might want to consider using the XCI build which already takes care of this issue.  We have added the necessary user mode quirks plus included relevant components you would need along with appropriate emulation library that would work with 64-bit hypervisor etc.

Hi Kamala,

Thanks for your response. Can you provide some pointers into the XCI
trees where I can see the related source code changes?

RE: Host S3

[Kamala Narasimhan]

You might want to look for enter-s3.sh script.  Since host S3/resume is impacted by different components running on the system and since XCI build already ensures that the components built by it plays along with host S3, you might be better off with XCI build so as not to chase yet another issue you might possibly run into that XCI build might have already taken care of...

RE: Host S3

[scorbin]

Hi Kamala,

I am trying to build the XCI tree and am having some issues.  The first
problem is that the make configuration for xenclient-ioemu is setup to
use alsa but libasound2 is not included in the XCI target packages.  I
avoided this issue by modifying xen-setup and configure in the
xenclient-ioemu directory to not use alsa.  The second issue is one I
can't get passed.  The build fails just after setting up
xenclient-linux.  Here is the output:

...

The build system is a fresh install of 32-bit Debian 5.01.

Any help you can provide on building XCI would be appreciated.

RE: Host S3

[Kamala Narasimhan]

I haven't encountered this error, so I am not sure.  One thing that comes to mind is to check the version of guilt on your system and possibly upgrade to a newer version if there is one.

Re: Host S3

[C I Dalton]

Some versions of guilt don't like comments following the patch file name
 on the same line - if you can't find one that does then this may
help...I suspect you'll find that the file:

/home/scorbin/build/repo/xenclient-linux-2.6.27/.git/patches/master/series

has lines like:

linux-2.6.18-xen.hg-832.c0f2f398aa3c # x86: Fix interaction of NTP and
dom0->xen time updates

Remove the comments from lines like that and re-run 'guilt-push -a' from
the root of that repo and go back to the make.

RE: Host S3

[scorbin]

I got the XCI build up and running but dom0 does not provide the
functionality I am looking for.  There is no ability to run X or GDM.
So far the issues I am seeing with host suspend/resume seem to be
graphics and SMP related, issues which XCI does not address.

I would like to get dom0 suspend/resume working with Ubuntu 8.04 or 9.04
running on top of Xen.  I have used s2ram, pm-suspend and some
roll-my-own scripts with less than stellar results.

The current issue I am looking at is that Xen's time is not working
after resume.  Both clocksource/1 and timer isr/1 print out persistent
"Time went backwards" messages.

So as not to risk dom0 security, we prefer X etc. in an appliance VM.  You could optionally enable X in dom0 and post relevant patches though our recommendation wouldn't be to enable X in dom0.

I have on occasions tried host S3 on varied environments (with Xen) including the ones you mentioned and have had success with host S3, of course with appropriate tweaks.

Hmm... I have seen this issue, more so with older versions of Xen.  I would recommend starting a separate thread on this mentioning the version of Xen with which you now encounter this issue.
