42 =========================================================
44 * **Extended port_id range from uint8_t to uint16_t.**
46 Increased port_id range from 8 bits to 16 bits in order to support more than
47 256 ports in dpdk. All ethdev APIs which have port_id as parameter are changed
50 * **Modified the return type of rte_eth_stats_reset.**
52 Changed return type of ``rte_eth_stats_reset`` from ``void`` to ``int``
53 so the caller may know whether a device supports the operation or not
54 and if the operation was carried out.
56 * **Added a new driver for Marvell Armada 7k/8k devices.**
58 Added the new mrvl net driver for Marvell Armada 7k/8k devices. See the
59 "Network Interface Controller Drivers" document for more details on this new
62 * **Updated mlx5 driver.**
64 Updated the mlx5 driver including the following changes:
66 * Enabled PMD to run on top of upstream linux kernel and rdma-core libs.
67 By that removed the dependency on specific Mellanox OFED libraries.
68 * Improved PMD latency performance.
69 * Improved PMD memory footprint.
70 * Supported vectorized Rx/Tx burst for ARMv8.
71 * Supported secondary process.
72 * Supported flow counters.
73 * Supported Rx hardware timestamp offload.
74 * Supported device removal event.
76 * **Added SoftNIC PMD.**
78 Added new SoftNIC PMD. This virtual device offers applications a software
79 fallback support for traffic management.
81 * **nfp: Added PF support.**
83 Previously Netronome's NFP PMD had just support for VFs. PF support is
84 just as a basic DPDK port and has no VF management yet.
86 PF support comes with firmware upload support which allows the PMD to
87 independently work from kernel netdev NFP drivers.
89 NFP 4000 devices are also now supported along with previous 6000 devices.
91 * **Updated bnxt PMD.**
93 Major enhancements include:
95 * Support for Flow API
96 * Support for Tx and Rx descriptor status functions
98 * **Add bus agnostic functions to cryptodev for PMD initialisation**
100 Adds new PMD assist functions ``rte_cryptodev_pmd_parse_input_args()``,
101 ``rte_cryptodev_pmd_create()`` and ``rte_cryptodev_pmd_destroy()`` which
102 are bus independent for driver to manage creation and destruction of new
105 * **Updated QAT crypto PMD.**
107 Performance enhancements:
109 * Removed atomics from the internal queue pair structure.
110 * Coalesce writes to HEAD CSR on response processing.
111 * Coalesce writes to TAIL CSR on request processing.
113 Additional support for:
117 * **Updated the AESNI MB PMD.**
119 The AESNI MB PMD has been updated with additional support for:
122 * DES DOCSIS BPI algorithm.
124 This requires the IPSec Multi-buffer library 0.47. For more details,
125 check out the AESNI MB PMD documenation.
127 * **Updated the OpenSSL PMD.**
129 The OpenSSL PMD has been updated with additional support for:
134 * **Added NXP DPAA SEC crypto PMD.**
136 A new "dpaa_sec" hardware based crypto PMD for NXP DPAA devices has been
137 added. See the "Crypto Device Drivers" document for more details on this
140 * **Added MRVL crypto PMD.**
142 A new crypto PMD has been added, which provides several ciphering and hashing
143 algorithms. All cryptography operations use the MUSDK library crypto API.
145 * **Add new benchmarking mode to dpdk-test-crypto-perf application.**
147 Added new "PMD cyclecount" benchmark mode to dpdk-test-crypto-perf application
148 that displays more detailed breakdown of CPU cycles used by hardware
151 * **Added IOMMU support to libvhost-user**
153 Implemented device IOTLB in Vhost-user backend, and enabled Virtio's IOMMU
156 * **Added Membership library (rte_member).**
158 Added membership library. It provides an API for DPDK applications to insert a
159 new member, delete an existing member, or query the existence of a member in a
160 given set, or a group of sets. For the case of a group of sets the library
161 will return not only whether the element has been inserted before in one of
162 the sets but also which set it belongs to.
164 The Membership Library is an extension and generalization of a traditional
165 filter (for example Bloom Filter) structure that has multiple usages in a wide
166 variety of workloads and applications. In general, the Membership Library is a
167 data structure that provides a “set-summary” and responds to set-membership
168 queries whether a certain member belongs to a set(s).
170 See the :ref:`Membership Library <Member_Library>` documentation in
171 the Programmers Guide document, for more information.
173 * **Added the Generic Segmentation Offload Library.**
175 Added the Generic Segmentation Offload (GSO) library to enable
176 applications to split large packets (e.g. MTU is 64KB) into small
177 ones (e.g. MTU is 1500B). Supported packet types are:
180 * VxLAN packets, which must have an outer IPv4 header, and contain
181 an inner TCP/IPv4 packet.
182 * GRE packets, which must contain an outer IPv4 header, and inner
185 The GSO library doesn't check if the input packets have correct
186 checksums, and doesn't update checksums for output packets.
187 Additionally, the GSO library doesn't process IP fragmented packets.
189 * **Added the Flow Classification Library.**
191 Added the Flow Classification library, it provides an API for DPDK
192 applications to classify an input packet by matching it against a set of flow
193 rules. It uses the librte_table API to manage the flow rules.
199 .. This section should contain bug fixes added to the relevant
200 sections. Sample format:
202 * **code/section Fixed issue in the past tense with a full stop.**
204 Add a short 1-2 sentence description of the resolved issue in the past
207 The title should contain the code/lib section like a commit message.
209 Add the entries in alphabetic order in the relevant sections below.
211 This section is a comment. do not overwrite or remove it.
212 Also, make sure to start the actual text at the margin.
213 =========================================================
219 * **Service core fails to call service callback due to atomic lock**
221 In a specific configuration of multi-thread unsafe services and service
222 cores, a service core previously did not correctly release the atomic lock
223 on the service. This would result in the cores polling the service, but it
224 looked like another thread was executing the service callback. The logic for
225 atomic locking of the services has been fixed and refactored for readability.
246 .. This section should contain new known issues in this release. Sample format:
248 * **Add title in present tense with full stop.**
250 Add a short 1-2 sentence description of the known issue in the present
251 tense. Add information on any known workarounds.

269 =========================================================
271 * **Ethdev device name length increased**
273 The size of internal device name is increased to 64 characters
274 to allow for storing longer bus specific name.
276 * **Service cores API updated for usability**
278 The service cores API has been changed, removing pointers from the API
279 where possible, instead using integer IDs to identify each service. This
280 simplifed application code, aids debugging, and provides better
281 encapsulation. A summary of the main changes made is as follows:
283 * Services identified by ID not by ``rte_service_spec`` pointer
284 * Reduced API surface by using ``set`` functions instead of enable/disable
285 * Reworked ``rte_service_register`` to provide the service ID to registrar
286 * Rework start and stop APIs into ``rte_service_runstate_set``
287 * Added API to set runstate of service implementation to indicate readyness
289 * **The following changes made in mempool library**
291 * Moved ``flags`` datatype from int to unsigned int for ``rte_mempool``.
292 * Removed ``__rte_unused int flag`` param from ``rte_mempool_generic_put``
293 and ``rte_mempool_generic_get`` API.
294 * Added ``flags`` param in ``rte_mempool_xmem_size`` and
295 ``rte_mempool_xmem_usage``.
297 * Xen dom0 in EAL was removed, as well as xenvirt PMD and vhost_xen.
299 * ``rte_mem_phy2mch`` was used in Xen dom0 to obtain the physical address;
300 remove this API as Xen dom0 support was removed.
302 * **Add return value to stats_get dev op API**
304 The ``stats_get`` dev op API return value has been changed to be int.
305 By this way PMDs can return an error value in case of failure at stats
306 getting process time.
308 * **Modified the rte_cryptodev_allocate_driver function in the cryptodev library.**
310 The function ``rte_cryptodev_allocate_driver()`` has been modified.
311 An extra parameter ``struct cryptodev_driver *crypto_drv`` has been added.
313 * **Removed virtual device bus specific functions from librte_cryptodev.**
315 The functions ``rte_cryptodev_vdev_parse_init_params()`` and
316 ``rte_cryptodev_vdev_pmd_init()`` have been removed from librte_cryptodev
317 and have been replaced by non bus specific functions
318 ``rte_cryptodev_pmd_parse_input_args()`` and ``rte_cryptodev_pmd_create()``.
320 * **Removed PCI device bus specific functions from librte_cryptodev.**
322 The functions ``rte_cryptodev_pci_generic_probe()`` and
323 ``rte_cryptodev_pci_generic_remove()`` have been removed from librte_cryptodev
324 and have been replaced by non bus specific functions
325 ``rte_cryptodev_pmd_create()`` and ``rte_cryptodev_pmd_destroy()``.
327 * **Removed deprecated functions to manage log level or type.**
329 The functions ``rte_set_log_level()``, ``rte_get_log_level()``,
330 ``rte_set_log_type()`` and ``rte_get_log_type()`` have been removed.
331 They are respectively replaced by ``rte_log_set_global_level()``,
332 ``rte_log_get_global_level()``, ``rte_log_set_level()`` and
333 ``rte_log_get_level()``.
339 .. This section should contain ABI changes. Sample format:
341 * Add a short 1-2 sentence description of the ABI change that was announced
342 in the previous releases and made in this release. Use fixed width quotes
343 for ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
345 This section is a comment. do not overwrite or remove it.
346 Also, make sure to start the actual text at the margin.
347 =========================================================
349 * **Extended port_id range.**
351 The size of the field ``port_id`` in the ``rte_eth_dev_data`` structure
352 changed, as described in the `New Features` section.
358 .. This section should contain removed items in this release. Sample format:
360 * Add a short 1-2 sentence description of the removed item in the past
