DPDK Release 24.07
==================
New Features
------------
* **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 Amazon ena (Elastic Network Adapter) driver.**
* Reworked the driver logger usage in order to improve Tx performance.
* Reworked the device uninitialization flow to ensure complete resource cleanup
and lay the groundwork for hot-unplug support.
* **Updated Intel ice driver.**
* Added support for E830 device family.
* Added support for configuring the Forward Error Correction (FEC) mode,
querying FEC capabilities and current FEC mode from a device.
* **Updated Intel i40e driver.**
* Added support for configuring the Forward Error Correction (FEC) mode,
querying FEC capabilities and current FEC mode from a device.
* **Updated Intel ixgbe driver.**
* Updated base code with E610 device family support.
* **Added Napatech ntnic net driver [EXPERIMENTAL].**
* Added the PMD for Napatech smartNIC:
- Ability to initialize the NIC (NT200A02)
- Supporting only one FPGA firmware (9563.55.39)
- Ability to bring up the 100G link
- Supporting QSFP/QSFP+/QSFP28 NIM
- Does not support datapath
* **Updated Marvell cnxk net driver.**
* Added support disabling custom meta aura
and separately use custom SA action support.
* Added MTU update for port representor.
* Added multi-segment support for port representor.
* **Updated NVIDIA mlx5 driver.**
* Added match with Tx queue.
* Added match with external Tx queue.
* Added match with E-Switch manager.
* Added async flow item and actions validation.
* Added global and per-port out of buffer counter for hairpin queues.
* Added hardware queue object context dump for Rx/Tx debugging.
* **Updated TAP driver.**
* Updated to support up to 8 queues when used by secondary process.
* Fixed support for 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.
* **Added AMD Pensando ionic crypto driver.**
Added a new crypto driver for AMD Pensando hardware accelerators.
* **Updated NVIDIA mlx5 crypto driver.**
* Added AES-GCM IPsec operation optimization.
* **Updated IPsec_MB crypto driver.**
* Made Kasumi and ChaCha-Poly PMDs to share the job code path
with AESNI_MB PMD.
* **Added UADK compress driver.**
Added a new compress driver for the UADK library. See the
:doc:`../compressdevs/uadk` guide for more details on this new driver.
* **Updated Marvell CNXK DMA driver.**
* Updated DMA driver internal pool to use higher chunk size,
effectively reducing the number of mempool allocs needed,
thereby increasing DMA performance.
* **Added Marvell Odyssey ODM DMA driver.**
* Added Marvell Odyssey ODM DMA device PMD.
* **Updated the DSW event device.**
* Added support for ``RTE_EVENT_DEV_CAP_IMPLICIT_RELEASE_DISABLE``,
allowing applications to take on new tasks without having completed
(released) the previous event batch. This in turn facilities DSW
use alongside high-latency look-aside hardware accelerators.
* **Updated the hash library.**
* Added defer queue reclamation via RCU.
* Added SVE support for bulk lookup.
Removed Items
-------------
* **Disabled the BPF library and net/af_xdp for 32-bit x86.**
BPF is not supported and the librte-bpf test fails on 32-bit x86 kernels.
So disable the library and the pmd.
* **Removed hisilicon DMA support for HIP09 platform.**
The DMA for HIP09 is no longer available,
so the support is removed from hisilicon driver for HIP09 platform.
API Changes
-----------
* mbuf: ``RTE_MARKER`` fields ``cacheline0`` and ``cacheline1``
have been removed from ``struct rte_mbuf``.
* hash: The ``rte_hash_sig_compare_function`` internal enum is not exposed
in the public API anymore.
ABI Changes
-----------
* No ABI change that would break compatibility with 23.11.
* eventdev/dma: Reorganize the experimental fastpath structure ``rte_event_dma_adapter_op``
to optimize the memory layout and improve performance.
