DPDK Release 24.07
==================
.. **Read this first.**
The text in the sections below explains how to update the release notes.
Use proper spelling, capitalization and punctuation in all sections.
Variable and config names should be quoted as fixed width text:
``LIKE_THIS``.
Build the docs and view the output file to ensure the changes are correct::
ninja -C build doc
xdg-open build/doc/guides/html/rel_notes/release_24_07.html
New Features
------------
.. This section should contain new features added in this release.
Sample format:
* **Add a title in the past tense with a full stop.**
Add a short 1-2 sentence description in the past tense.
The description should be enough to allow someone scanning
the release notes to understand the new feature.
If the feature adds a lot of sub-features you can use a bullet list
like this:
* Added feature foo to do something.
* Enhanced feature bar to do something else.
Refer to the previous release notes for examples.
Suggested order in release notes items:
* Core libs (EAL, mempool, ring, mbuf, buses)
* Device abstraction libs and PMDs (ordered alphabetically by vendor name)
- ethdev (lib, PMDs)
- cryptodev (lib, PMDs)
- eventdev (lib, PMDs)
- etc
* Other libs
* Apps, Examples, Tools (if significant)
This section is a comment. Do not overwrite or remove it.
Also, make sure to start the actual text at the margin.
=======================================================
* **Introduced pointer compression library.**
Library provides functions to compress and decompress arrays of pointers
which can improve application performance under certain conditions.
Performance test was added to help users evaluate performance on their setup.
* **Added API to retrieve memory locations of objects in a mempool.**
Added mempool API ``rte_mempool_get_mem_range`` and
``rte_mempool_get_obj_alignment`` to retrieve information about the memory
range and the alignment of objects stored in a mempool.
* **Updated AF_XDP driver.**
* Enabled multi-interface (UDS) support with AF_XDP Device Plugin.
The argument ``use_cni`` was limiting a pod to a single netdev/interface.
The new ``dp_path`` parameter removed this limitation
and maintains backward compatibility for applications using the ``use_cni``
vdev argument with the AF_XDP Device Plugin.
* Integrated AF_XDP Device Plugin eBPF map pinning support.
The argument ``use_map_pinning`` was added to allow Kubernetes Pods
to use AF_XDP with DPDK, and run with limited privileges,
without having to do a full handshake over a Unix Domain Socket
with the Device Plugin.
* **Updated TAP driver.**
* Updated to support up to 8 queues when used by secondary process.
* Fixed support of RSS flow action to work with current Linux kernels
and BPF tooling.
Will only be enabled if clang, libbpf 1.0 and bpftool are available.
* **Updated Wangxun ngbe driver.**
* Added SSE/NEON vector datapath.
* **Updated Wangxun txgbe driver.**
* Added SSE/NEON vector datapath.
