Hi,
I am using xen4.6 and Linux-4.4 as dom0 and domU on Jacinto j6 board.
The system is able to boot and create domains successfully. Now, I am
trying to enable hibernation in domU. The hibernation seems to be
completed successfully. After hibernating domU and recreating domU. It
is able to resume but gives following error messages for vbd in kernel
logs

Xen 4.6 has been released 3 years and is 5 releases old. You should use
a recent Xen and Linux when doing development as bug may have been fixed
in recent version. Please reproduce your error on recent version (Xen
4.10 at least).

Hi Julien,
As you specified earlier I am now able to boot using xen4.10. I am
using linux4.4 as dom0 as well as domU.In domU, I have enabled
hibenation related configs and I am trying suspend to disk.With xen
4.10, hibernation is done sucessfuly but resume crashes.
I have used given config file for domU.
name = "domU"
kernel = "/ZI-uh1"
memory = 200
vcpus = 1
cpus = 1
disk = [ 'phy:/rfs1.img,xvda,rw']
extra = 'no_console_suspend loglevel=8 console=hvc0 xenconsole=tty
earlyprintk=xx
en rw dhcp=off resume=/dev/xvda resume_offset=331776 root=/dev/xvda rootwait'
The hibernate(domU console) and resume logs are shown as below:

It would have been nice to switch to a more recent Linux as well because
I don't think anyone worked on suspend/resume 2 years ago. There are
effort to support suspend/resume in Xen (and I guess guest) but I
suspect some work is still missing in newer kernel. Although that would
be a better start than a 2 years old kernel for the guest.

I don't seem to be able to find that commit in Linux and it also says
dirty. What are your modification on top of Linux 4.4?

That's the only log you have? I would have at least expected a stack
trace afterwards.

Looking at the log and Linux 4.17, none of the PV drivers seem to have
suspend/resume callback. This might be the reason of the crash as from
Xen PoV this is a new guest so the memory and event channel have not
been configured. The guest should really do it again.
It looks like there are some code in drivers/xen/manage.c to handle
suspend request from the toolstack. I am not entirely sure why we need
our own way to suspend and not re-used the Linux one.
Jurgen, Boris, do you know if suspend-to-disk from the guest console
works on x86?
Mirela, as you are working on suspend/resume. Have you looked at the
guest side? If so, do you have any insights on the problem?
Cheers,

Yes, the support for guest suspend to RAM in Xen is required. I'm
preparing that series for the submission.
Briefly, the suspend to RAM relies on PSCI system_suspend. Xen has to
support resuming a suspended guest from an entry point that is
provided as system suspend argument, as well as some other vcpu
context/device related stuff. That is not supported today.
Although suspend-to-disk/hibernate has a lots in common with suspend
to RAM, I believe it has nothing to do with PSCI system suspend and
the suspend flow I'm implementing in Xen. These features should be
independent and mechanisms shouldn't have anything in common from the
perspective of supporting the guest suspend to ram vs disk in Xen.
Hibernate should rather be based on shutdown or so, but I'm not
familiar with the details.
Sorry if I wasn't really helpful. I hope others can comment and point
you in the right direction.
Best regards,
Mirela

It looks like it was not supported. Amazon recently sent an RFC to
support it (see [1]). This seems to have some architecture specific code
but only for x86. Arm bits would need to be implemented.

Hi Julien,
I have applied the given patches sent by amazon on mainline linux
4.17.4 branch commit bdeb8f5.
Even after applying given patches the crash as seen below is
encountered in domU while trying to hibernate to disk usin xen-4.10.

Also, one more observation I have had is that hibernation image
creation does not crash for linux mainline version upto v4.7.10 but
not for later versions.
Although for v4.7.10 after resume and getting console, commands like
sync or ps do not give any output and hangs till I give kill command
(Ctrl + C).
Given below is the log for attempting hibernation with linux mainline
v4.7.10 (commit id b3afc45)

Is there any plan to support hibernation from userspace on arm on xen
for any future release ? If not then what implementations I need to
add in xen and linux to enable hibernation on domU for arm?

I am not sure to follow this. Which version are you using for Dom0? For
