[PATCH for 7.2 v3 00/13] testing and doc updates (pre-PR)

[Alex Bennée]

Hi,

This contains my last set of fixes which didn't make it in the last
pull request I sent. I've dropped the console peek patch which
unearthed a number of additional tests which can't handle even the
smallest delay in avocado draining the console chardev. As a result we
still occasionally miss login prompts but the rest of the tests are
more stable.

New in this iteration:

  - more bumping of timeouts
  - disable the tcg virt tests in CI in favour of a new alpine based one
  - cirrus updates for macos

The following need review:

 - gitlab: integrate coverage report (1 acks, 1 sobs)
 - tests/avocado: skip aarch64 cloud TCG tests in CI
 - tests/avocado: introduce alpine virt test for CI

Alex Bennée (8):
  tests/docker: allow user to override check target
  docs/devel: add a maintainers section to development process
  docs/devel: make language a little less code centric
  docs/devel: simplify the minimal checklist
  docs/devel: try and improve the language around patch review
  tests/avocado: introduce alpine virt test for CI
  tests/avocado: skip aarch64 cloud TCG tests in CI
  gitlab: integrate coverage report

[PATCH v3 01/13] Run docker probe only if docker or podman are available

[Alex Bennée]

From: Stefan Weil <sw@weilnetz.de>

The docker probe uses "sudo -n" which can cause an e-mail with a security warning
each time when configure is run. Therefore run docker probe only if either docker
or podman are available.

That avoids the problematic "sudo -n" on build environments which have neither
docker nor podman installed.

[PATCH v3 02/13] tests/avocado/machine_aspeed.py: Reduce noise on the console for SDK tests

[Alex Bennée]

From: Cédric Le Goater <clg@kaod.org>

The Aspeed SDK images are based on OpenBMC which starts a lot of
services. The output noise on the console can break from time to time
the test waiting for the logging prompt.

Change the U-Boot bootargs variable to add "quiet" to the kernel
command line and reduce the output volume. This also drops the test on
the CPU id which was nice to have but not essential.

This is useful when trying to bisect a particular failing test behind
a docker run. For example:

    TEST_COMMAND="meson test qtest-arm/qos-test" \
    J=9 V=1

[PATCH v3 04/13] docs/devel: add a maintainers section to development process

[Alex Bennée]

We don't currently have a clear place in the documentation to describe
the roles and responsibilities of a maintainer. Lets create one so we
can. I've moved a few small bits out of other files to try and keep
everything in one place.

+
+The Role of Maintainers
+=======================
+
+Maintainers are a critical part of the project's contributor ecosystem.
+They come from a wide range of backgrounds from unpaid hobbyists
+working in their spare time to employees who work on the project as
+part of their job. Maintainer activities include:
+
+  - reviewing patches and suggesting changes
+  - collecting patches and preparing pull requests
+  - tending to the long term health of their area
+  - participating in other project activities
+
+They are also human and subject to the same pressures as everyone else
+including overload and burnout. Like everyone else they are subject
+to project's :ref:`code_of_conduct` and should also be exemplars of
+excellent community collaborators.
+
+The MAINTAINERS file
+--------------------
+
+The `MAINTAINERS
+<https://gitlab.com/qemu-project/qemu/-/blob/master/MAINTAINERS>`__
+file contains the canonical list of who is a maintainer. The file
+is machine readable so an appropriately configured git (see
+:ref:`cc_the_relevant_maintainer`) can automatically Cc them on
+patches that touch their area of code.
+
+The file also describes the status of the area of code to give an idea
+of how actively that section is maintained.
+
+.. list-table:: Meaning of support status in MAINTAINERS
+   :widths: 25 75

+   * - Orphan
+     - No current maintainer.
+   * - Obsolete
+     - Old obsolete code, should use something else.
+
+Please bear in mind that even if someone is paid to support something
+it does not mean they are paid to support you. This is open source and
+the code comes with no warranty and the project makes no guarantees
+about dealing with bugs or features requests.
+
+
+
+Becoming a reviewer
+-------------------
+
+Most maintainers start by becoming subsystem reviewers. While anyone
+is welcome to review code on the mailing list getting added to the
+MAINTAINERS file with a line like::
+
+  R: Random Hacker <rhacker@example.com>
+
+will ensure that patches touching a given subsystem will automatically
+be CC'd to you.
+
+Becoming a maintainer
+---------------------
+
+Maintainers are volunteers who put themselves forward or have been
+asked by others to keep an eye on an area of code. They have generally
+demonstrated to the community, usually via contributions and code
+reviews, that they have a good understanding of the subsystem. They
+are also trusted to make a positive contribution to the project and
+work well with the other contributors.
+
+The process is simple - simply send a patch to the list that updates
+the ``MAINTAINERS`` file. Sometimes this is done as part of a larger
+series when a new sub-system is being added to the code base. This can
+also be done by a retiring maintainer who nominates their replacement
+after discussion with other contributors.
+
+Once the patch is reviewed and merged the only other step is to make
+sure your GPG key is signed.
+
+.. _maintainer_keys:
+
+Maintainer GPG Keys
+~~~~~~~~~~~~~~~~~~~
+
+GPG is used to sign pull requests so they can be identified as really

[PATCH v3 08/13] tests/avocado: Raise timeout for boot_linux.py:BootLinuxPPC64.test_pseries_tcg

[Alex Bennée]

From: Peter Maydell <peter.maydell@linaro.org>

On my machine, a debug build of QEMU takes about 260 seconds to
complete this test, so with the current timeout value of 180 seconds
it always times out.  Double the timeout value to 360 so the test
definitely has enough time to complete.

[PATCH v3 09/13] tests/avocado: introduce alpine virt test for CI

[Alex Bennée]

The boot_linux tests download and run a full cloud image boot and
start a full distro. While the ability to test the full boot chain is
worthwhile it is perhaps a little too heavy weight and causes issues
in CI. Fix this by introducing a new alpine linux ISO boot in
machine_aarch64_virt.

This boots a fully loaded -cpu max with all the bells and whistles in
31s on my machine. A full debug build takes around 180s on my machine
so we set a more generous timeout to cover that.

We don't add a test for lesser GIC versions although there is some
coverage for that already in the boot_xen.py tests. If we want to
introduce more comprehensive testing we can do it with a custom kernel
and initrd rather than a full distro boot.

[PATCH v3 12/13] tests/avocado/boot_linux.py: Bump aarch64 virt test timeout to 720s

[Alex Bennée]

From: Peter Maydell <peter.maydell@linaro.org>

The two tests
tests/avocado/boot_linux.py:BootLinuxAarch64.test_virt_tcg_gicv2
tests/avocado/boot_linux.py:BootLinuxAarch64.test_virt_tcg_gicv3

take quite a long time to run, and the current timeout of 240s
is not enough for the tests to complete on slow machines:
we've seen these tests time out in the gitlab CI in the
'avocado-system-alpine' CI job, for instance. The timeout
is also insufficient for running the test with a debug build
of QEMU: on my machine the tests take over 10 minutes to run
in that config.

Push the timeout up to 720s so that the test definitely has
enough time to complete.

[PATCH v3 13/13] ci: replace x86_64 macos-11 with aarch64 macos-12

[Alex Bennée]

From: Daniel P. Berrangé <berrange@redhat.com>

The Cirrus CI service has announced the intent to discontinue
support for x86_64 macOS CI runners. They already have aarch64
runners available and require all projects to switch to these
images before Jan 1st 2023. The different architecture is
merely determined by the image name requested.

For aarch64 they only support macOS 12 onwards. At the same
time our support policy only guarantees the most recent 2
major versions, so macOS 12 is already technically our min
version.

We could add a line in MAINTAINERS 'Descriptions of section entries'
header: "If you modify this section, please keep in sync with the
description in docs/devel/maintainers.rst".

Although 'R:' tag means 'designated reviewer', such reviewers is
expected to provide regular spontaneous feedback. Otherwise being
subscribed to the list is sufficient.

I am not sure about restricting to BUILD_DIR, I'd rather use an
externally prebuilt image, i.e.:
https://snapshots.linaro.org/components/kernel/leg-virt-tianocore-edk2-upstream/4710/QEMU-AARCH64/RELEASE_GCC5/

(I'd like to use these Avocado tests with a distrib provided QEMU
binary).

Anyhow can be fixed later, so:

The previous patches removed these jobs from GitLab CI, so
this shouldn't be a problem there anymore, but the next part

Just to let you know, this patch is now upstream via target-arm.next,
so you can drop it from your queue.

I've used a slightly different form for the flow:

  Becoming a reviewer
  -------------------

  Most maintainers start by becoming subsystem reviewers. While anyone
  is welcome to review code on the mailing list getting added to the
  MAINTAINERS file with a line like::

    R: Random Hacker <rhacker@example.com>

  marks you as a 'designated reviewer' - expected to provide regular
  spontaneous feedback. This will ensure that patches touching a given
  subsystem will automatically be CC'd to you.

we can of course always improve later ;-)

Revisiting this patch, asking for some real name instead of alias
was at least helpful during patch review, we could address the
contributor by its name. Addressing an acronym is socially weird

Is it that weird? We use nicks all the time on IRC.

The only driver for real names for the signoff is its harder to have
confidence the contribution is valid because you might not be able to
find who is behind an anonymous nick if something comes up later.

The Signed-off-by is intended as a legal attestation of permission
to contribute. Having the signoff use an obviously anonymous nick
could be said to undermine the legal value of the Signed-off-by.

That's not to say something that /looks/ like a real name is
actually the persons real name - we can't prove that without ID
checks which we're not going to do.

Something that looks like a real name is at least plausible to
accept as a persons' real world identity, where as a nick is
clearly just an online persona where there is an explicit intent
to hide the real identify. This kind of distinction / intent often
matters in the legal arena.

With regards,
Daniel
