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.**

103 * **nfp: Added PF support.**
105 Previously Netronome's NFP PMD had just support for VFs. PF support is
106 just as a basic DPDK port and has no VF management yet.
108 PF support comes with firmware upload support which allows the PMD to
109 independently work from kernel netdev NFP drivers.
111 NFP 4000 devices are also now supported along with previous 6000 devices.
113 * **Updated bnxt PMD.**
115 Major enhancements include:

159 added. See the "Crypto Device Drivers" document for more details on this
162 * **Added MRVL crypto PMD.**
164 A new crypto PMD has been added, which provides several ciphering and hashing
165 algorithms. All cryptography operations use the MUSDK library crypto API.
167 * **Add new benchmarking mode to dpdk-test-crypto-perf application.**
169 Added new "PMD cyclecount" benchmark mode to dpdk-test-crypto-perf application
170 that displays more detailed breakdown of CPU cycles used by hardware
173 * **Added the Security Offload Library.**
175 Added an experimental library - rte_security. It provide security APIs for
176 protocols like IPSec using inline ipsec offload to ethernet device or full
177 protocol offload with lookaside crypto device.
179 See the "Security_Library" section of the DPDK Programmers Guide document,
180 for more information.
182 * **Updated DPAA2_SEC crypto driver.**
184 Updated dpaa2_sec crypto PMD to support rte_security lookaside protocol
187 * **Updated IXGBE ethernet driver.**

191 * **Updated ipsec-secgw application**
193 Updated ipsec-secgw sample application to support rte_security actions for
194 ipsec inline and full protocol offload using lookaside crypto offload.
196 * **Added IOMMU support to libvhost-user**
198 Implemented device IOTLB in Vhost-user backend, and enabled Virtio's IOMMU
199 feature. The feature is disabled by default, and can be enabled by setting
200 RTE_VHOST_USER_IOMMU_SUPPORT flag at vhost device registration time.
202 * **Added the Event Ethernet Adapter Library.**
204 Added the Event Ethernet Adapter library. It provices APIs for
205 eventdev applications to configure the ethdev to eventdev packet flow.
207 * **Added Membership library (rte_member).**
209 Added membership library. It provides an API for DPDK applications to insert a
210 new member, delete an existing member, or query the existence of a member in a
211 given set, or a group of sets. For the case of a group of sets the library
212 will return not only whether the element has been inserted before in one of
213 the sets but also which set it belongs to.
215 The Membership Library is an extension and generalization of a traditional
216 filter (for example Bloom Filter) structure that has multiple usages in a wide
217 variety of workloads and applications. In general, the Membership Library is a
218 data structure that provides a “set-summary” and responds to set-membership
219 queries whether a certain member belongs to a set(s).
221 See the :ref:`Membership Library <Member_Library>` documentation in
222 the Programmers Guide document, for more information.
224 * **Added the Generic Segmentation Offload Library.**
226 Added the Generic Segmentation Offload (GSO) library to enable
227 applications to split large packets (e.g. MTU is 64KB) into small
228 ones (e.g. MTU is 1500B). Supported packet types are:
231 * VxLAN packets, which must have an outer IPv4 header, and contain
232 an inner TCP/IPv4 packet.
233 * GRE packets, which must contain an outer IPv4 header, and inner
236 The GSO library doesn't check if the input packets have correct
237 checksums, and doesn't update checksums for output packets.
238 Additionally, the GSO library doesn't process IP fragmented packets.
240 * **Added the Flow Classification Library.**
242 Added the Flow Classification library, it provides an API for DPDK
243 applications to classify an input packet by matching it against a set of flow
244 rules. It uses the librte_table API to manage the flow rules.
250 .. This section should contain bug fixes added to the relevant
251 sections. Sample format:
253 * **code/section Fixed issue in the past tense with a full stop.**
255 Add a short 1-2 sentence description of the resolved issue in the past
258 The title should contain the code/lib section like a commit message.
260 Add the entries in alphabetic order in the relevant sections below.
262 This section is a comment. do not overwrite or remove it.
263 Also, make sure to start the actual text at the margin.
264 =========================================================
270 * **Service core fails to call service callback due to atomic lock**
272 In a specific configuration of multi-thread unsafe services and service
273 cores, a service core previously did not correctly release the atomic lock
274 on the service. This would result in the cores polling the service, but it
275 looked like another thread was executing the service callback. The logic for
276 atomic locking of the services has been fixed and refactored for readability.
297 .. This section should contain new known issues in this release. Sample format:
299 * **Add title in present tense with full stop.**
301 Add a short 1-2 sentence description of the known issue in the present
302 tense. Add information on any known workarounds.

312 .. This section should contain API changes. Sample format:
314 * Add a short 1-2 sentence description of the API change. Use fixed width
315 quotes for ``rte_function_names`` or ``rte_struct_names``. Use the past
318 This section is a comment. do not overwrite or remove it.
319 Also, make sure to start the actual text at the margin.
320 =========================================================
322 * **Ethdev device name length increased**
324 The size of internal device name is increased to 64 characters
325 to allow for storing longer bus specific name.
327 * **Ethdev flag RTE_ETH_DEV_DETACHABLE was removed**
329 This flag is not necessary anymore, with the new hotplug implementation.
330 It is now removed from the ether library. Its semantic is expressed at the bus
333 * **Service cores API updated for usability**
335 The service cores API has been changed, removing pointers from the API
336 where possible, instead using integer IDs to identify each service. This
337 simplifed application code, aids debugging, and provides better
338 encapsulation. A summary of the main changes made is as follows:
340 * Services identified by ID not by ``rte_service_spec`` pointer
341 * Reduced API surface by using ``set`` functions instead of enable/disable
342 * Reworked ``rte_service_register`` to provide the service ID to registrar
343 * Rework start and stop APIs into ``rte_service_runstate_set``
344 * Added API to set runstate of service implementation to indicate readyness
346 * **The following changes made in mempool library**
348 * Moved ``flags`` datatype from int to unsigned int for ``rte_mempool``.
349 * Removed ``__rte_unused int flag`` param from ``rte_mempool_generic_put``
350 and ``rte_mempool_generic_get`` API.
351 * Added ``flags`` param in ``rte_mempool_xmem_size`` and
352 ``rte_mempool_xmem_usage``.
354 * Xen dom0 in EAL was removed, as well as xenvirt PMD and vhost_xen.
356 * ``rte_mem_phy2mch`` was used in Xen dom0 to obtain the physical address;
357 remove this API as Xen dom0 support was removed.
359 * **Some data type, structure members and functions related to physical address
360 are deprecated and have new alias with IOVA wording.**
362 * ``phys_addr_t`` can be often replaced by ``rte_iova_t`` of same size.
363 * ``RTE_BAD_PHYS_ADDR`` is often replaced by ``RTE_BAD_IOVA`` of same value.
364 * ``rte_memseg.phys_addr`` is aliased with ``rte_memseg.iova_addr``.
365 * ``rte_mem_virt2phy()`` can often be replaced by ``rte_mem_virt2iova``.
366 * ``rte_malloc_virt2phy`` is aliased with ``rte_malloc_virt2iova``.
367 * ``rte_memzone.phys_addr`` is aliased with ``rte_memzone.iova``.
368 * ``rte_mempool_objhdr.physaddr`` is aliased with ``rte_mempool_objhdr.iova``.
369 * ``rte_mempool_memhdr.phys_addr`` is aliased with ``rte_mempool_memhdr.iova``.
370 * ``rte_mempool_virt2phy()`` can be replaced by ``rte_mempool_virt2iova()``.
371 * ``rte_mempool_populate_phys*()`` are aliased with ``rte_mempool_populate_iova*()``
372 * ``rte_mbuf.buf_physaddr`` is aliased with ``rte_mbuf.buf_iova``.
373 * ``rte_mbuf_data_dma_addr*()`` are aliased with ``rte_mbuf_data_iova*()``.
374 * ``rte_pktmbuf_mtophys*`` are aliased with ``rte_pktmbuf_iova*()``.
376 * **PCI bus API moved outside of the EAL**
378 The PCI bus previously implemented within the EAL has been moved.
379 A first part has been added as an RTE library providing PCI helpers to
380 parse device locations or other such utilities.
381 A second part consisting in the actual bus driver has been moved to its
382 proper subdirectory, without changing its functionalities.
384 As such, several PCI-related functions are not proposed by the EAL anymore:
389 * rte_pci_ioport_read
390 * rte_pci_ioport_unmap
391 * rte_pci_ioport_write
395 * rte_pci_read_config
398 * rte_pci_unmap_device
400 * rte_pci_write_config
402 These functions are made available either as part of ``librte_pci`` or
405 * **Moved vdev bus APIs outside of the EAL**
407 Moved the following APIs from ``librte_eal`` to ``librte_bus_vdev``:
409 * ``rte_vdev_register``
410 * ``rte_vdev_uninit``
411 * ``rte_vdev_unregister``
413 * **Add return value to stats_get dev op API**
415 The ``stats_get`` dev op API return value has been changed to be int.
416 By this way PMDs can return an error value in case of failure at stats
417 getting process time.
419 * **Modified the rte_cryptodev_allocate_driver function in the cryptodev library.**
421 The function ``rte_cryptodev_allocate_driver()`` has been modified.
422 An extra parameter ``struct cryptodev_driver *crypto_drv`` has been added.
424 * **Removed virtual device bus specific functions from librte_cryptodev.**
426 The functions ``rte_cryptodev_vdev_parse_init_params()`` and
427 ``rte_cryptodev_vdev_pmd_init()`` have been removed from librte_cryptodev
428 and have been replaced by non bus specific functions
429 ``rte_cryptodev_pmd_parse_input_args()`` and ``rte_cryptodev_pmd_create()``.
431 * ``rte_cryptodev_create_vdev`` was removed to avoid the dependency on vdev
432 in librte_cryptodev; instead, users can call rte_vdev_init() directly.
434 * **Removed PCI device bus specific functions from librte_cryptodev.**
436 The functions ``rte_cryptodev_pci_generic_probe()`` and
437 ``rte_cryptodev_pci_generic_remove()`` have been removed from librte_cryptodev
438 and have been replaced by non bus specific functions
439 ``rte_cryptodev_pmd_create()`` and ``rte_cryptodev_pmd_destroy()``.
441 * **Removed deprecated functions to manage log level or type.**
443 The functions ``rte_set_log_level()``, ``rte_get_log_level()``,
444 ``rte_set_log_type()`` and ``rte_get_log_type()`` have been removed.
445 They are respectively replaced by ``rte_log_set_global_level()``,
446 ``rte_log_get_global_level()``, ``rte_log_set_level()`` and
447 ``rte_log_get_level()``.
449 * **Removed ``mbuf`` flags ``PKT_RX_VLAN_PKT`` and ``PKT_RX_QINQ_PKT``.**
451 The ``mbuf`` flags ``PKT_RX_VLAN_PKT`` and ``PKT_RX_QINQ_PKT`` have
452 been removed since their behavior were not properly described.
454 * **Added ``mbuf`` flags ``PKT_RX_VLAN`` and ``PKT_RX_QINQ``.**
456 Two ``mbuf`` flags have been added to indicate that the VLAN
457 identifier has been saved in in the ``mbuf`` structure. For instance:
459 - if VLAN is not stripped and TCI is saved: ``PKT_RX_VLAN``
460 - if VLAN is stripped and TCI is saved: ``PKT_RX_VLAN | PKT_RX_VLAN_STRIPPED``
462 * **Modified the vlan_offload_set_t function prototype in the ethdev library.**
464 Changed the function prototype of ``vlan_offload_set_t``. The return value
465 has been changed from ``void`` to ``int`` so the caller to knows whether
466 the backing device supports the operation or if the operation was
467 successfully performed.
473 .. This section should contain ABI changes. Sample format:
475 * Add a short 1-2 sentence description of the ABI change that was announced
476 in the previous releases and made in this release. Use fixed width quotes
477 for ``rte_function_names`` or ``rte_struct_names``. Use the past tense.
479 This section is a comment. do not overwrite or remove it.
480 Also, make sure to start the actual text at the margin.
481 =========================================================
483 * **Extended port_id range.**
485 The size of the field ``port_id`` in the ``rte_eth_dev_data`` structure
486 changed, as described in the `New Features` section.
488 * **New parameter added to rte_eth_dev.**
490 New parameter ``security_ctx`` added to ``rte_eth_dev`` to support security
491 operations like IPSec inline.
493 * **New parameter added to rte_cryptodev.**
495 New parameter ``security_ctx`` added to ``rte_cryptodev`` to support security
496 operations like lookaside crypto.
