The bug has been fixed in staging and we already got a push.

I'm not quite sure why the bisector thought this commit was the culprit,
but I wouldn't spend time on this...

And that fix is commit c787425fdf ("libxc: fix the types used in
xc_dom_image to build HVM guests")? I ask because the commit
message doesn't say anything like that, and it's not immediately
clear why only an *-xsm test should have been affected by the
issue.

It's not that XSM is particularly affected. It's just that particular
test case  happened to run on merlot{0,1} which have a lot of memory.

The HVM test case has a property when it knows the host has large enough
free memory, it will try to bump the guest memory beyond 4G -- I
deliberately made it work like that so that it can catch bug like this
one introduced by misuse of types.

Wait a moment. I might have come to the conclusion too fast.

The pass was on italia*, not merlot*.  I'm a bit confused why this test
didn't run on merlot* because AIUI OSSTest test case is "sticky" to
failure.

Anyway, I will wait for Ian to come in and consult him about this.

The problem was not related to XSM in any way, this specific XSM test
failed simply because the HVM guest had more than 4GB of RAM and the
toolstack was 32bits (which was the only way to trigger it). I wrongly
used xen_pfn_t to store byte memory addresses in xc_dom_image.

When you say "the bug", which bug do you mean ?  I think the bisector
is fingering this commit because of the types bug introduced in that
commit and fixed in
  "[PATCH v2] libxc: fix the types used in xc_dom_image to build HVM guests"

> but I wouldn't spend time on this...

I need to know if the bisector is producing confusing or wrong output
:-).

I'm now confident that the bisector is doing the right thing. I dig into
various flights to understand what the long list of flights actually
meant. It might be helpful we have page explaining how to interpret this
email, too.

In a previous reply I said I was confused because the flight that got a
push (63026) had test-amd64-i386-xl-qemuu-debianhvm-amd64-xsm run on
italia*, not merlot*, so I wasn't sure if OSSTest was doing the right
thing.  But then I looked again, the aforementioned test case did get a
pass on merlot* in 63024. So in 63026 OSSTest worked out the tree was
fine.

With that in mind, I'm confident that the bug (misuse of types) is fixed
in staging and master.

You mean the stuff at the end of the "bisection complete" mail ?

That's output mostly useful for debugging osstest, I think.  It's
provided there in case the revision graph web page is not suitable for
your purposes; for example, so that you can c&p more easily, or for
when you don't want to feed your browser a massive image.

But you're right that a document explaining the meaning of bisection
results is probably helpful.

Yes, the lines following "Searching for test results:"

For example, there are lines like:

 62583 [host=chardonnay0]
 ...

which don't contain changeset information. And by the look of it I
couldn't immediately work out  what it meant.

If I'm not mistaken (after digging out that particular flight), those
lines mean "the flight mentioned in first column had a pass of this test
case, and it was run on host BLAH". But then it didn't mention the cs of
Xen (or the targeted branch), which isn't very helpful.

OK, I will just skip those in the future...

Yeah. At least mentioning what to look at and what to ignore would be
helpful.

      iommu: make iommu_inclusive_mapping a suboption of dom0-iommu
      
      Introduce a new dom0-iommu=map-inclusive generic option that
      supersedes iommu_inclusive_mapping. The previous behavior is preserved
      and the option should only be enabled by default on Intel hardware.
