patchew - gitlab-ci notifications during the Xen 4.16 cycle

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hi all,

During the last 6 months we have been working on improving the Xen
Project gitlab-ci and patchew infrastructure.

You can see the results from gitlab-ci tests on the staging branch here:

https://gitlab.com/xen-project/xen/-/pipelines
https://gitlab.com/xen-project/xen/-/pipelines/269678673

In addition, and more interestingly, now we have patchew integration.
Patchew picks up patch series sent to xen-devel by any contributor and
commits them to branches under this repository:

https://gitlab.com/xen-project/patchew/xen

Then, gitlab-ci tests start automatically. Patchew waits for the results
and send a notification email. You can see patchew pipelines here:

https://gitlab.com/xen-project/patchew/xen/-/pipelines

All this typically happens before patches are even reviewed. Today the
patchew notification emails are only sent to us in the Gitlab-CI working
group. But the good news is that we think the results got to the point
where they are reliable enough that it would be good to share them with
the community.

We plan to have patchew send email notifications to xen-devel starting
from the beginning of the 4.16 development cycle.

Stay tuned.

Cheers,

Stefano
