DAMON Maintainer Entry Profile
==============================
The DAMON subsystem covers the files that are listed in 'DATA ACCESS MONITOR'
section of 'MAINTAINERS' file.
The mailing lists for the subsystem are damon@lists.linux.dev and
linux-mm@kvack.org. Patches should be made against the `mm-unstable tree
<https://git.kernel.org/akpm/mm/h/mm-unstable>`_ whenever possible and posted
to the mailing lists.
SCM Trees
---------
There are multiple Linux trees for DAMON development. Patches under
development or testing are queued in `damon/next
<https://git.kernel.org/sj/h/damon/next>`_ by the DAMON maintainer.
Sufficiently reviewed patches will be queued in `mm-unstable
<https://git.kernel.org/akpm/mm/h/mm-unstable>`_ by the memory management
subsystem maintainer. After more sufficient tests, the patches will be queued
in `mm-stable <https://git.kernel.org/akpm/mm/h/mm-stable>`_, and finally
pull-requested to the mainline by the memory management subsystem maintainer.
Note again the patches for `mm-unstable tree
<https://git.kernel.org/akpm/mm/h/mm-unstable>`_ are queued by the memory
management subsystem maintainer. If the patches requires some patches in
`damon/next tree <https://git.kernel.org/sj/h/damon/next>`_ which not yet merged
in mm-unstable, please make sure the requirement is clearly specified.
Submit checklist addendum
-------------------------
When making DAMON changes, you should do below.
- Build changes related outputs including kernel and documents.
- Ensure the builds introduce no new errors or warnings.
- Run and ensure no new failures for DAMON `selftests
<https://github.com/damonitor/damon-tests/blob/master/corr/run.sh#L49>`_ and
`kunittests
<https://github.com/damonitor/damon-tests/blob/master/corr/tests/kunit.sh>`_.
Further doing below and putting the results will be helpful.
- Run `damon-tests/corr
<https://github.com/damonitor/damon-tests/tree/master/corr>`_ for normal
changes.
- Run `damon-tests/perf
<https://github.com/damonitor/damon-tests/tree/master/perf>`_ for performance
changes.
Key cycle dates
---------------
Patches can be sent anytime. Key cycle dates of the `mm-unstable
<https://git.kernel.org/akpm/mm/h/mm-unstable>`_ and `mm-stable
<https://git.kernel.org/akpm/mm/h/mm-stable>`_ trees depend on the memory
management subsystem maintainer.
Review cadence
--------------
The DAMON maintainer does the work on the usual work hour (09:00 to 17:00,
Mon-Fri) in PT (Pacific Time). The response to patches will occasionally be
slow. Do not hesitate to send a ping if you have not heard back within a week
of sending a patch.
Mailing tool
------------
Like many other Linux kernel subsystems, DAMON uses the mailing lists
(damon@lists.linux.dev and linux-mm@kvack.org) as the major communication
channel. There is a simple tool called `HacKerMaiL
<https://github.com/damonitor/hackermail>`_ (``hkml``), which is for people who
are not very familiar with the mailing lists based communication. The tool
could be particularly helpful for DAMON community members since it is developed
and maintained by DAMON maintainer. The tool is also officially announced to
support DAMON and general Linux kernel development workflow.
In other words, `hkml <https://github.com/damonitor/hackermail>`_ is a mailing
tool for DAMON community, which DAMON maintainer is committed to support.
Please feel free to try and report issues or feature requests for the tool to
the maintainer.
Community meetup
----------------
DAMON community is maintaining two bi-weekly meetup series for community
members who prefer synchronous conversations over mails.
The first one is for any discussion between every community member. No
reservation is needed.
The seconds one is for discussions on specific topics between restricted
members including the maintainer. The maintainer shares the available time
slots, and attendees should reserve one of those at least 24 hours before the
time slot, by reaching out to the maintainer.
Schedules and available reservation time slots are available at the Google `doc
<https://docs.google.com/document/d/1v43Kcj3ly4CYqmAkMaZzLiM2GEnWfgdGbZAH3mi2vpM/edit?usp=sharing>`_.
There is also a public Google `calendar
<https://calendar.google.com/calendar/u/0?cid=ZDIwOTA4YTMxNjc2MDQ3NTIyMmUzYTM5ZmQyM2U4NDA0ZGIwZjBiYmJlZGQxNDM0MmY4ZTRjOTE0NjdhZDRiY0Bncm91cC5jYWxlbmRhci5nb29nbGUuY29t>`_
that has the events. Anyone can subscribe it. DAMON maintainer will also
provide periodic reminder to the mailing list (damon@lists.linux.dev).
