including tests which could not be run:

    After commit 5dff8e9eedc7, "libxc/libxl: fill xc_hvm_build_args in
    libxl" is introduced, we won't check to set args.mmio_size inside
    xc_hvm_build as before. So instead, we need to do this before call
    that.

    xen: Install unstripped version -syms version into /usr/lib/debug
    
    xen-*-syms cannot actually be booted, so putting it in /boot is a bit
    misleading. It also happens to cause a warning from update-grub (so at
    least it doesn't end up in grub.cfg)
    
    /usr/lib/debug seems to be a pretty common path for installing such
    debug info.

commit fff2304e471e6db2136bad9237f2ed18580615f1
Author: Ian Campbell <ian.campbell@citrix.com>

    xen: arm: Log a warning message when a deprecated hypercall is used
    
    A few folks have been caught out by OSes which call e.g.
    HYPERVISOR_event_channel_op_compat which has been deprecated since
    3.2.2 (i.e. long before Xen on ARM). Existing x86 code can still
    safely and quietly using those calls, waiting for an unsuspecting ARM
    porter to turn up and trip over it. This turns out to be rather
    perplexing when it happens, since it can be obscured e.g. by various
    conditionals like __XEN_INTERFACE_VERSION__ what is actually being
    called.
    
    Note that I'm making a distinction here between hypercalls which are
    simply not used/implemented on arm (yet) and those which were
    deprecated and replaced by a newer variant prior to Xen on ARM even
    being invented.  The latter will never be implemented on ARM and have
    non-deprecated aliases leading to confusion so those are the ones for
    which a warning is useful.

    libxl: Fix uninitialised rc in libxl__domain_save_device_model
    
    c3c8da9 "libxl: ao: datacopier callback gets an rc" caused
    libxl__domain_save_device_model() to pass its rc directly into the
    callback.
    
    However in the preexisting code, there were 3 "goto out;" paths which
    left rc uninitialised.  This causes a build failure with GCC 4.8's
    -Wmaybe-uninitialized.
    
    Set the rc explicitly on each goto out path.

This one seems to have fallen into the merlot trap.

>  test-armhf-armhf-xl-credit2  15 guest-start/debian.repeat fail REGR. vs. 58965

From
http://logs.test-lab.xenproject.org/osstest/results/history/test-armhf-armhf-xl-credit2/xen-unstable.html it appears this one is sporadically unreliable on cubietruck, but works just fine on arndale.

Comparing to
http://logs.test-lab.xenproject.org/osstest/results/history/test-armhf-armhf-xl/xen-unstable.html 
it looks to be credit2 specific.

d8v0 has a PC at 0xffff000c, which will be the entry point for the
prefetch abort handler. ABT_LR shows it came from 0xffff0010 which is
the data abt handler, which uses the same banked LR as prefetch abt so
we don't know where it came from.

SVR_LR shows that the last function call done in kernel mode was a call
to fdt_check_header from early_init_dt_verify, but that might have been
ages ago.

Guest logs ends with it shutting down, but I think that is the previous
test step completing.

Ian, I believe you observed some other instances of this in triaging
another failure last week.

http://logs.test-lab.xenproject.org/osstest/logs/59040/test-amd64-amd64-xl-qemuu-debianhvm-amd64/fiano0---var-log-xen-qemu-dm-debianhvm.guest.osstest.log

is pretty uninteresting, we should perhaps arrange to remove some
"quiet"'s from guest commands lines somewhere, or to frob the guest
console to include ttyS0, which it isn't clear it does.

vnc snapshot just shows the login prompt.

The bisector looks to be working on this one
http://logs.test-lab.xenproject.org/osstest/results/bisect/xen-unstable/test-amd64-amd64-xl-qemuu-debianhvm-amd64.guest-start.2.html
but I don't think it is going to conclude anything, since it looks intermittent.

Yes, but I'm afraid I don't remember exactly which failure.

This is quite weird.

I just spotted near the end of

(which is still weird)...

I saw this bug since the introduction of amd64-i386 stubdom test case.
Now it looks like intermittent, i.e. we failed at the beginning, passed
at some point, now it failed again.

http://logs.test-lab.xenproject.org/osstest/results/history/test-amd64-i386-xl-qemut-stubdom-debianhvm-amd64-xsm/xen-unstable.html
gives the history of it.

It looks as if italia* and chardonnay* might be susceptible but really I
don't think there is sufficient information to draw any particular
conclusion wrt the frequency of this bug or whether it might be host
specific or not, since the passes on other hosts are general singletons.

The 64-bit dom0 case is at
http://logs.test-lab.xenproject.org/osstest/results/history/test-amd64-amd64-xl-qemut-stubdom-debianhvm-amd64-xsm/xen-unstable.html
I'm not sure what, if anything, it tells us though. It does look to be
more less prone to errors (it having now hit merlot notwithstanding,
although it seems to reliably pass the install phase there).

One potentially interesting case is that in the 32-bit dom0 case the
stubdom is also 32-bit, while in the other case the stubdom is 64-bit.

I'm not convinced using a 32-bit stubdom is the right choice, but I
suppose it ought to work.

Ian.

Note that we do have one pass vs five fails on italia0. The same goes
for chardonay0 (one pass vs four fails). It's really weird.

Yeah, it ought to work. But making it actually work requires much
effort. I would say let's mark that failure none blocking for the
moment.

Yes, noted... I shall have a look.

From what I recall, failures varies a bit, in terms of what the state of
the system (vcpus active/idle, etc.) when the fail itself happens.

If I'm not confusing this with something else, I've seen instances where
everything was completely idle and instances, like this one, where there
is something going on... As I said, I'll have a look.

Thanks for this. My nonexistent knowledge of ARM internals limits by
quite a bit the amount of information that I can extract from this
trace... but this is already something.

I'll ask if there is anything that is ARM specific that I need but can't
figure out.
