45 =========================================================
47 * **Added function to allow releasing internal EAL resources on exit.**
49 During ``rte_eal_init()`` EAL allocates memory from hugepages to enable its
50 core libraries to perform their tasks. The ``rte_eal_cleanup()`` function
51 releases these resources, ensuring that no hugepage memory is leaked. It is
52 expected that all DPDK applications call ``rte_eal_cleanup()`` before
53 exiting. Not calling this function could result in leaking hugepages, leading
54 to failure during initialization of secondary processes.
56 * **Added igb, ixgbe and i40e ethernet driver to support RSS with flow API.**
58 Added support for igb, ixgbe and i40e NICs with existing RSS configuration
59 using the ``rte_flow`` API.
61 Also enabled queue region configuration using the ``rte_flow`` API for i40e.
63 * **Updated i40e driver to support PPPoE/PPPoL2TP.**
65 Updated i40e PMD to support PPPoE/PPPoL2TP with PPPoE/PPPoL2TP supporting
66 profiles which can be programmed by dynamic device personalization (DDP)
69 * **Added MAC loopback support for i40e.**
71 Added MAC loopback support for i40e in order to support test tasks requested
72 by users. It will setup ``Tx -> Rx`` loopback link according to the device
75 * **Added support of run time determination of number of queues per i40e VF.**
77 The number of queue per VF is determined by its host PF. If the PCI address
78 of an i40e PF is ``aaaa:bb.cc``, the number of queues per VF can be
79 configured with EAL parameter like ``-w aaaa:bb.cc,queue-num-per-vf=n``. The
80 value n can be 1, 2, 4, 8 or 16. If no such parameter is configured, the
81 number of queues per VF is 4 by default.
83 * **Updated mlx5 driver.**
85 Updated the mlx5 driver including the following changes:
87 * Enabled compilation as a plugin, thus removed the mandatory dependency with rdma-core.
88 With the special compilation, the rdma-core libraries will be loaded only in case
89 Mellanox device is being used. For binaries creation the PMD can be enabled, still not
90 requiring from every end user to install rdma-core.
91 * Improved multi-segment packet performance.
92 * Changed driver name to use the PCI address to be compatible with OVS-DPDK APIs.
93 * Extended statistics for physical port packet/byte counters.
94 * Converted to the new offloads API.
95 * Supported device removal check operation.
97 * **Updated mlx4 driver.**
99 Updated the mlx4 driver including the following changes:
101 * Enabled compilation as a plugin, thus removed the mandatory dependency with rdma-core.
102 With the special compilation, the rdma-core libraries will be loaded only in case
103 Mellanox device is being used. For binaries creation the PMD can be enabled, still not
104 requiring from every end user to install rdma-core.
105 * Improved data path performance.
106 * Converted to the new offloads API.
107 * Supported device removal check operation.
109 * **Added NVGRE and UDP tunnels support in Solarflare network PMD.**
111 Added support for NVGRE, VXLAN and GENEVE tunnels.
113 * Added support for UDP tunnel ports configuration.
114 * Added tunneled packets classification.
115 * Added inner checksum offload.
117 * **Added AVF (Adaptive Virtual Function) net PMD.**
119 Added a new net PMD called AVF (Adaptive Virtual Function), which supports
120 IntelĀ® Ethernet Adaptive Virtual Function (AVF) with features such as:
123 * SSE vectorized Rx/Tx burst
128 * Jumbo frame and MTU setting
131 * Rx/Tx descriptor status
132 * Link status update/event
134 * **Added feature supports for live migration from vhost-net to vhost-user.**
136 Added feature supports for vhost-user to make live migration from vhost-net
137 to vhost-user possible. The features include:
139 * ``VIRTIO_F_ANY_LAYOUT``
140 * ``VIRTIO_F_EVENT_IDX``
141 * ``VIRTIO_NET_F_GUEST_ECN``, ``VIRTIO_NET_F_HOST_ECN``
142 * ``VIRTIO_NET_F_GUEST_UFO``, ``VIRTIO_NET_F_HOST_UFO``
143 * ``VIRTIO_NET_F_GSO``
145 Also added ``VIRTIO_NET_F_GUEST_ANNOUNCE`` feature support in virtio pmd.
146 In a scenario where the vhost backend doesn't have the ability to generate
147 RARP packets, the VM running virtio pmd can still be live migrated if
148 ``VIRTIO_NET_F_GUEST_ANNOUNCE`` feature is negotiated.
150 * **Updated the AESNI-MB PMD.**
152 The AESNI-MB PMD has been updated with additional support for:
156 * **Updated the DPAA_SEC crypto driver to support rte_security.**
158 Updated the ``dpaa_sec`` crypto PMD to support ``rte_security`` lookaside
159 protocol offload for IPsec.
161 * **Added Wireless Base Band Device (bbdev) abstraction.**
163 The Wireless Baseband Device library is an acceleration abstraction
164 framework for 3gpp Layer 1 processing functions that provides a common
165 programming interface for seamless operation on integrated or discrete
166 hardware accelerators or using optimized software libraries for signal
169 The current release only supports 3GPP CRC, Turbo Coding and Rate
170 Matching operations, as specified in 3GPP TS 36.212.
172 See the :doc:`../prog_guide/bbdev` programmer's guide for more details.
174 * **Added New eventdev Ordered Packet Distribution Library (OPDL) PMD.**
176 The OPDL (Ordered Packet Distribution Library) eventdev is a specific
177 implementation of the eventdev API. It is particularly suited to packet
178 processing workloads that have high throughput and low latency requirements.
179 All packets follow the same path through the device. The order in which
180 packets follow is determined by the order in which queues are set up.
181 Events are left on the ring until they are transmitted. As a result packets
182 do not go out of order.
184 With this change, applications can use the OPDL PMD via the eventdev api.
186 * **Added new pipeline use case for dpdk-test-eventdev application.**
188 Added a new "pipeline" use case for the ``dpdk-test-eventdev`` application.
189 The pipeline case can be used to simulate various stages in a real world
190 application from packet receive to transmit while maintaining the packet
191 ordering. It can also be used to measure the performance of the event device
192 across the stages of the pipeline.
194 The pipeline use case has been made generic to work with all the event
195 devices based on the capabilities.
197 * **Updated Eventdev sample application to support event devices based on capability.**
199 Updated the Eventdev pipeline sample application to support various types of
200 pipelines based on the capabilities of the attached event and ethernet
201 devices. Also, renamed the application from software PMD specific
202 ``eventdev_pipeline_sw_pmd`` to the more generic ``eventdev_pipeline``.
204 * **Added Rawdev, a generic device support library.**
206 The Rawdev library provides support for integrating any generic device type with
207 the DPDK framework. Generic devices are those which do not have a pre-defined
208 type within DPDK, for example, ethernet, crypto, event etc.
210 A set of northbound APIs have been defined which encompass a generic set of
211 operations by allowing applications to interact with device using opaque
212 structures/buffers. Also, southbound APIs provide a means of integrating devices
213 either as as part of a physical bus (PCI, FSLMC etc) or through ``vdev``.
215 See the :doc:`../prog_guide/rawdev` programmer's guide for more details.
217 * **Added new multi-process communication channel.**
219 Added a generic channel in EAL for multi-process (primary/secondary) communication.
220 Consumers of this channel need to register an action with an action name to response
221 a message received; the actions will be identified by the action name and executed
222 in the context of a new dedicated thread for this channel. The list of new APIs:
224 * ``rte_mp_register`` and ``rte_mp_unregister`` are for action (un)registration.
225 * ``rte_mp_sendmsg`` is for sending a message without blocking for a response.
226 * ``rte_mp_request`` is for sending a request message and will block until
227 it gets a reply message which is sent from the peer by ``rte_mp_reply``.
229 * **Added GRO support for VxLAN-tunneled packets.**
231 Added GRO support for VxLAN-tunneled packets. Supported VxLAN packets
232 must contain an outer IPv4 header and inner TCP/IPv4 headers. VxLAN
233 GRO doesn't check if input packets have correct checksums and doesn't
234 update checksums for output packets. Additionally, it assumes the
235 packets are complete (i.e., ``MF==0 && frag_off==0``), when IP
236 fragmentation is possible (i.e., ``DF==0``).
238 * **Increased default Rx and Tx ring size in sample applications.**
240 Increased the default ``RX_RING_SIZE`` and ``TX_RING_SIZE`` to 1024 entries
241 in testpmd and the sample applications to give better performance in the
242 general case. The user should experiment with various Rx and Tx ring sizes
243 for their specific application to get best performance.
245 * **Added new DPDK build system using the tools "meson" and "ninja" [EXPERIMENTAL].**
247 Added support for building DPDK using ``meson`` and ``ninja``, which gives
248 additional features, such as automatic build-time configuration, over the
249 current build system using ``make``. For instructions on how to do a DPDK build
250 using the new system, see the instructions in ``doc/build-sdk-meson.txt``.
254 This new build system support is incomplete at this point and is added
255 as experimental in this release. The existing build system using ``make``
256 is unaffected by these changes, and can continue to be used for this
257 and subsequent releases until such time as it's deprecation is announced.
