linux-arm-xen branch, commit access, etc.

[Ian Jackson]

Currently we are running our ARM tests in osstest off a branch in
Stefano's personal Linux tree.  This is a bit unsatisfactory.

We would like to switch to a branch that Julien can push to too, and
that is in a more official place.

There are two options:

 1. Create an ARM-specific Xen tree.  Currently we don't have many
    ARM-specific trees but I don't see a problem with this.  So
    we could create
        /arm/linux.git
    on xenbits.

 2. Use a branch name within /linux-pvops.git, the main Linux
    tree on xenbits.  This would mean making Julien a committer.

What do people think would be best ?

Also, separately, surely Julien should be listed in MAINTAINERS for
the Xen ARM stuff in upstream Linux ?  He doesn't seem to be at least
in the version I have lying about here...

Thanks,
Ian.

I agree with Konrad. The reason why that branch is there is that
initially we needed a couple of patches to run Linux on Exynos5 boards
(Arndale). Today, vanilla releases should work. For example, 4.13 has
everything we need as far as I can tell. I think it is time to remove
the special branch.

If it turns out that we still need a special branch (I don't think we
do), then 1. is a good option.

No, that is correct, at the moment I am the only maintainer for Xen on
ARM support in Linux. I'll talk to Julien but the attention it requires
is very limited.  Patches specific to arch/arm/xen and arch/arm64/xen/
are very few, in the order of 10 in the last year. It doesn't
necessarily need more than one maintainer.

So vanilla kernels are going to work well on our new ARM64 boxes, eg
ThunderX, and whatever we come up with for new ARM32 testing too ?

In.

I think so: ThunderX and other server platforms should be more
"standard" than small embedded boards. But if we decide to buy some
small and cheap ARM32 boards, such as Linaro HiKey, they tend to still
require special kernel trees.

In other words: I think we should be able to get rid of the special tree
for the hardware that we have today, but I cannot guarantee that we
won't ever need it in the future.

Julien, do you think we need to keep a special linux tree around for Xen
on ARM testing in OSSTest or we can start using vanilla kernel releases?
I would love to get rid of it, if you know of any reasons why we have to
keep it, this is the time to speak :-)

It is what you wish :). For instance Thunder-X support has been fully made
upstream (ACPI + DT) only recently.

In other words: I think we should be able to get rid of the special tree
for the hardware that we have today, but I cannot guarantee that we
won't ever need it in the future.


IIRC we are going to get some renesas board recently. Do you know if
upstream will work?

I think it would be better to keep aroundSome platform may be available
before the code is merged.

Sure.


Ian,

let's create a /arm/linux.git tree on xenbits where both Julien and I
can push. The idea is that we'll try to use vanilla kernel releases but
we'll keep it around just in case we'll need special patches for
hardware support in the future. If it turns out that we don't actually
need it, we can get rid of it in a year or two.

We'll initialize /arm/linux.git based on the current linux-arm-xen
branch. /arm/linux.git will replace linux-arm-xen in OSSTest.

Sounds good?

Thanks,

Stefano

I don't mind as long as I have access to the arm linux tree. Ian do you 
have any opinions?

No-one objected to this, so I have done it.  There's a bare repo
there.

Let me know when you've populated it and I'll change osstest.

The tree has been populated based on Stefano's tree. Branch linux-arm-xen.

Thank you! Once we get the push, I will update the tree to the latest
