107 See the :doc:`../vdpadevs/mlx5` guide for more details on this driver.
109 * **Added support for virtio-PMD notification data.**
111 Added support for virtio-PMD notification data so that the driver
112 passes extra data (besides identifying the virtqueue) in its device
113 notifications, expanding the notifications to include the avail index and
114 avail wrap counter (When split ring is used, the avail wrap counter is not
115 included in the notification data).
117 * **Updated testpmd application.**
119 Added support for ESP and L2TPv3 over IP rte_flow patterns to the testpmd
122 * **Added algorithms to cryptodev API.**
124 Added new algorithms to the cryptodev API:
126 * ECDSA (Elliptic Curve Digital Signature Algorithm) is added to
127 asymmetric crypto library specifications.
128 * ECPM (Elliptic Curve Point Multiplication) is added to
129 asymmetric crypto library specifications.
131 * **Added synchronous Crypto burst API.**
133 A new API has been introduced in the crypto library to handle synchronous cryptographic
134 operations allowing it to achieve performance gains for cryptodevs which use
135 CPU based acceleration, such as Intel AES-NI. An implementation for aesni_gcm
136 cryptodev is provided. The IPsec example application and ipsec library itself
137 were changed to allow utilization of this new feature.
139 * **Added handling of mixed algorithms in encrypted digest requests in QAT PMD.**
141 Added handling of mixed algorithms in encrypted digest hash-cipher
142 (generation) and cipher-hash (verification) requests (e.g. SNOW3G + ZUC or
143 ZUC + AES CTR) in QAT PMD possible when running on GEN3 QAT hardware.
144 Such algorithm combinations are not supported on GEN1/GEN2 hardware
145 and executing the request returns ``RTE_CRYPTO_OP_STATUS_INVALID_SESSION``.
147 * **Queue-pairs are now thread-safe on Intel QuickAssist Technology (QAT) PMD.**
149 Queue-pairs are thread-safe on Intel CPUs but Queues are not (that is, within
150 a single queue-pair all enqueues to the TX queue must be done from one thread
151 and all dequeues from the RX queue must be done from one thread, but enqueues
152 and dequeues may be done in different threads.).
154 * **Updated the ZUC PMD.**
156 * Transitioned underlying library from libSSO ZUC to intel-ipsec-mb
157 library (minimum version required 0.53).
158 * Removed dynamic library limitation, so PMD can be built as a shared
161 * **Updated the KASUMI PMD.**
163 * Transitioned underlying library from libSSO KASUMI to intel-ipsec-mb
164 library (minimum version required 0.53).
166 * **Updated the SNOW3G PMD.**
168 * Transitioned underlying library from libSSO SNOW3G to intel-ipsec-mb
169 library (minimum version required 0.53).
171 * **Changed armv8 crypto PMD external dependency.**
173 Changed armv8 crypto PMD external dependency. The
174 armv8 crypto PMD now depends on the Arm crypto library, and Marvell's
175 armv8 crypto library is not used anymore. The library name has been changed
176 from armv8_crypto to AArch64crypto.
178 * **Added inline IPsec support to Marvell OCTEON TX2 PMD.**
180 Added inline IPsec support to Marvell OCTEON TX2 PMD. With this feature,
181 applications will be able to offload entire IPsec offload to the hardware.
182 For the configured sessions, hardware will do the lookup and perform
183 decryption and IPsec transformation. For the outbound path, applications
184 can submit a plain packet to the PMD, and it will be sent out on the wire
185 after doing encryption and IPsec transformation of the packet.
187 * **Added Marvell OCTEON TX2 End Point rawdev PMD.**
189 Added a new OCTEON TX2 rawdev PMD for End Point mode of operation.
190 See ``rawdevs/octeontx2_ep`` for more details on this new PMD.
192 * **Added event mode to l3fwd sample application.**
194 Added event device support for the ``l3fwd`` sample application. It demonstrates
195 usage of poll and event mode IO mechanism under a single application.
197 * **Added cycle-count mode to the compression performance tool.**
199 Enhanced the compression performance tool by adding a cycle-count mode
200 which can be used to help measure and tune hardware and software PMDs.
202 * **Added OpenWrt howto guide.**
204 Added document which describes how to enable DPDK on OpenWrt in both virtual and
211 * **Disabled building all the Linux kernel modules by default.**
213 In order to remove the build time dependency on the Linux kernel,
214 the Technical Board decided to disable all the kernel modules
215 by default from 20.02 version.
217 * **Removed coalescing feature from Intel QuickAssist Technology (QAT) PMD.**
219 The internal tail write coalescing feature was removed as not compatible with
220 dual-thread feature. It was replaced with a threshold feature. At busy times
221 if only a small number of packets can be enqueued, each enqueue causes
222 an expensive MMIO write. These MMIO write occurrences can be optimized by using
223 the new threshold parameter on process start. Please see QAT documentation for
230 * No change in this release.
233 .. _20_02_abi_changes:
238 * No change, kept ABI v20. DPDK 20.02 is compatible with DPDK 19.11.
240 * The soname for each stable ABI version should be just the ABI version major
241 number without the minor number. Unfortunately both major and minor were used
242 in the v19.11 release, causing version v20.x releases to be incompatible with
245 The `commit f26c2b39b271 <https://git.dpdk.org/dpdk/commit/?id=f26c2b39b271>`_
246 fixed the issue by switching from 2-part to 3-part ABI version numbers so that
247 we can keep v20.0 as soname and using the final digits to identify the DPDK
248 20.x releases which are ABI compatible.
