* Don't break compilation between commits with forward dependencies in a patchset.
Each commit should compile on its own to allow for ``git bisect`` and continuous integration testing.

* Add documentation, if relevant, in the form of Doxygen comments or a User Guide in RST format.
See the :ref:`Documentation Guidelines <doc_guidelines>`.
A good way of thinking about whether a patch should be split is to consider whether the change could be
applied without dependencies as a backport.
+It is better to keep the related documentation changes in the same patch
+file as the code, rather than one big documentation patch at then end of a
+patchset. This makes it easier for future maintenance and development of the
+code.

As a guide to how patches should be structured run ``git log`` on similar files.

+
+`Coverity <https://scan.coverity.com/projects/dpdk-data-plane-development-kit>`_
+is a tool for static code analysis.
+It is used as a cloud-based service used to scan the DPDK source code,
+and alert developers of any potential defects in the source code.
+When fixing an issue found by Coverity, the patch must contain a Coverity issue ID
+in the body of the commit message. For example::
+
+
+ doc: fix some parameter description
+
+ Update the docs, fixing description of some parameter.
+
+ Coverity issue: 12345
+ Fixes: abcdefgh1234 ("doc: add some parameter")
+ Cc: author@example.com

+ Signed-off-by: Alex Smith <alex.smith@example.com>
+
+
+`Bugzilla <https://bugs.dpdk.org>`_
+is a bug- or issue-tracking system.
+Bug-tracking systems allow individual or groups of developers
+effectively to keep track of outstanding problems with their product.
+When fixing an issue raised in Bugzilla, the patch must contain
+a Bugzilla issue ID in the body of the commit message.
+For example::
+
+ doc: fix some parameter description
+
+ Update the docs, fixing description of some parameter.

+Patch for Stable Releases
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+All fix patches to the master branch that are candidates for backporting
+should also be CCed to the `stable@dpdk.org <http://mails.dpdk.org/listinfo/stable>`_
+mailing list.
+In the commit message body the Cc: stable@dpdk.org should be inserted as follows::
+
+ doc: fix some parameter description
+
+ Update the docs, fixing description of some parameter.
+
+ Fixes: abcdefgh1234 ("doc: add some parameter")
+ Cc: stable@dpdk.org

Creating Patches

Checking Compilation
--------------------
-Compilation of patches and changes should be tested using the the ``test-build.sh`` script in the ``devtools``
+Compilation of patches and changes should be tested using the ``test-build.sh`` script in the ``devtools``
directory of the DPDK repo::
devtools/test-build.sh x86_64-native-linuxapp-gcc+next+shared

* ``DPDK_DEP_CFLAGS``
* ``DPDK_DEP_LDFLAGS``
-* ``DPDK_DEP_MOFED`` (y/[n])
* ``DPDK_DEP_PCAP`` (y/[n])
* ``DPDK_NOTIFY`` (notify-send)
git send-email --to maintainer@some.org --cc dev@dpdk.org 000*.patch
+Script ``get-maintainer.sh`` can be used to select maintainers automatically::
+
+ git send-email --to-cmd ./devtools/get-maintainer.sh --cc dev@dpdk.org 000*.patch
+
New additions can be sent without a maintainer::
git send-email --to dev@dpdk.org 000*.patch
git send-email --to dev@dpdk.org --in-reply-to <1234-foo@bar.com> 000*.patch
The Message ID can be found in the raw text of emails or at the top of each Patchwork patch,
-`for example <http://dpdk.org/dev/patchwork/patch/7646/>`_.
+`for example <http://patches.dpdk.org/patch/7646/>`_.
Shallow threading (``--thread --no-chain-reply-to``) is preferred for a patch series.
Once submitted your patches will appear on the mailing list and in Patchwork.
The options ``--annotate`` and ``confirm = always`` are recommended for checking patches before sending.
+Backporting patches for Stable Releases
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sometimes a maintainer or contributor wishes, or can be asked, to send a patch
+for a stable release rather than mainline.
+In this case the patch(es) should be sent to ``stable@dpdk.org``,
+not to ``dev@dpdk.org``.
+
+Given that there are multiple stable releases being maintained at the same time,
+please specify exactly which branch(es) the patch is for
+using ``git send-email --subject-prefix='PATCH 16.11' ...``
+and also optionally in the cover letter or in the annotation.
