57 =========================================================
59 * **FreeBSD now supports `--base-virtaddr` EAL option.**
61 FreeBSD version now also supports setting base virtual address for mapping
62 pages and resources into its address space.
64 * **Added Lock-free Stack for aarch64.**
66 The lock-free stack implementation is enabled for aarch64 platforms.
68 * **Extended pktmbuf mempool private structure.**
70 rte_pktmbuf_pool_private structure was extended to include flags field
71 for future compatibility.
72 As per 19.11 release this field is reserved and should be set to 0
75 * **Changed mempool allocation behaviour.**
77 Objects are no longer across pages by default.
78 It may consume more memory when using small memory pages.
80 * **Added support of dynamic fields and flags in mbuf.**
82 This new feature adds the ability to dynamically register some room
83 for a field or a flag in the mbuf structure. This is typically used
84 for specific offload features, where adding a static field or flag
85 in the mbuf is not justified.
87 * **Added hairpin queue.**
89 On supported NICs, we can now setup haipin queue which will offload packets
90 from the wire, backto the wire.

101 * Rx metadata is delivered to host via a dynamic field of ``rte_mbuf`` with
102 PKT_RX_DYNF_METADATA.
104 * **Added ethdev API to set supported packet types**
106 * Added new API ``rte_eth_dev_set_ptypes`` that allows an application to
107 inform PMD about reduced range of packet types to handle.
108 * This scheme will allow PMDs to avoid lookup to internal ptype table on Rx
109 and thereby improve Rx performance if application wishes do so.
111 * **Added Rx offload flag to enable or disable RSS update**
113 * Added new Rx offload flag `DEV_RX_OFFLOAD_RSS_HASH` which can be used to
114 enable/disable PMDs write to `rte_mbuf::hash::rss`.
115 * PMDs notify the validity of `rte_mbuf::hash:rss` to the application
116 by enabling `PKT_RX_RSS_HASH ` flag in `rte_mbuf::ol_flags`.

282 introduced to evaluate and perform custom functional and performance tests
283 for IPsec SAD implementation.
285 * Support fragmented packets in inline crypto processing mode with fallback
286 ``lookaside-none`` session. Corresponding changes are also added in IPsec
287 Security Gateway application.

307 * Added a console command to testpmd app, ``show port (port_id) ptypes`` which
308 gives ability to print port supported ptypes in different protocol layers.
309 * Packet type detection disabled by default for the supported PMDs.
311 * **Added new example l2fwd-event application.**
313 Added an example application `l2fwd-event` that adds event device support to
314 traditional l2fwd example. It demonstrates usage of poll and event mode IO
315 mechanism under a single application.
317 * **Added build support for Link Time Optimization.**
319 LTO is an optimization technique used by the compiler to perform whole
320 program analysis and optimization at link time. In order to do that
321 compilers store their internal representation of the source code that
322 the linker uses at the final stage of compilation process.
324 See :doc:`../prog_guide/lto` for more information:
326 * **Added IOVA as VA support for KNI.**
328 * Added IOVA = VA support for KNI, KNI can operate in IOVA = VA mode when
329 `iova-mode=va` EAL option is passed to the application or when bus IOVA
330 scheme is selected as RTE_IOVA_VA. This mode only works on Linux Kernel
331 versions above 4.9.0.
333 * Due to IOVA to KVA address translations, based on the KNI use case there
334 can be a performance impact. For mitigation, forcing IOVA to PA via EAL
335 "--iova-mode=pa" option can be used, IOVA_DC bus iommu scheme can also
336 result in IOVA as PA.
342 .. This section should contain removed items in this release. Sample format:
344 * Add a short 1-2 sentence description of the removed item
347 This section is a comment. Do not overwrite or remove it.
348 Also, make sure to start the actual text at the margin.
349 =========================================================
351 * Removed library-level ABI versions. These have been replaced with a single
352 project-level ABI version for non-experimental libraries and an ABI version of
353 ``0`` for experimental libraries. Review the :doc:`../contributing/abi_policy`
354 and :doc:`../contributing/abi_versioning` guides for more information.
356 * Removed duplicated set of commands for Rx offload configuration from testpmd::
358 port config all crc-strip|scatter|rx-cksum|rx-timestamp|
359 hw-vlan|hw-vlan-filter|hw-vlan-strip|hw-vlan-extend on|off
361 The testpmd commands set that can be used instead
362 in order to enable or disable Rx offloading on all Rx queues of a port is::
364 port config <port_id> rx_offload crc_strip|scatter|
365 ipv4_cksum|udp_cksum|tcp_cksum|timestamp|
366 vlan_strip|vlan_filter|vlan_extend on|off
368 * Removed AF_XDP pmd_zero copy vdev argument. Support is now auto-detected.

373 * L3 Forwarding in a Virtualization Environment
375 * Netmap Compatibility
376 * Quota and Watermark
379 * Removed arm64-dpaa2-* build config. arm64-dpaa-* can now build for both
380 dpaa and dpaa2 platforms.
386 .. This section should contain API changes. Sample format:
388 * sample: Add a short 1-2 sentence description of the API change
389 which was announced in the previous releases and made in this release.
390 Start with a scope label like "ethdev:".
391 Use fixed width quotes for ``function_names`` or ``struct_names``.
394 This section is a comment. Do not overwrite or remove it.
395 Also, make sure to start the actual text at the margin.
396 =========================================================
398 * eal: made the ``lcore_config`` struct and global symbol private.
400 * eal: removed the ``rte_cpu_check_supported`` function, replaced by
401 ``rte_cpu_is_supported`` since dpdk v17.08.
403 * eal: removed the ``rte_malloc_virt2phy`` function, replaced by
404 ``rte_malloc_virt2iova`` since v17.11.
406 * eal: made the ``rte_config`` struct and ``rte_eal_get_configuration``
409 * mem: hid the internal ``malloc_heap`` structure and the
410 ``rte_malloc_heap.h`` header.
412 * vfio: removed ``rte_vfio_dma_map`` and ``rte_vfio_dma_unmap`` that have
413 been marked as deprecated in release 19.05.
414 ``rte_vfio_container_dma_map`` and ``rte_vfio_container_dma_unmap`` can
415 be used as substitutes.
417 * pci: removed the following functions deprecated since dpdk v17.11:
419 - ``eal_parse_pci_BDF`` replaced by ``rte_pci_addr_parse``
420 - ``eal_parse_pci_DomBDF`` replaced by ``rte_pci_addr_parse``
421 - ``rte_eal_compare_pci_addr`` replaced by ``rte_pci_addr_cmp``
423 * The network structure ``esp_tail`` has been prefixed by ``rte_``.
425 * The network definitions of PPPoE ethertypes have been prefixed by ``RTE_``.
427 * The network structure for MPLS has been prefixed by ``rte_``.
429 * ethdev: changed ``rte_eth_dev_infos_get`` return value from ``void`` to
430 ``int`` to provide a way to report various error conditions.
432 * ethdev: changed ``rte_eth_promiscuous_enable`` and
433 ``rte_eth_promiscuous_disable`` return value from ``void`` to ``int`` to
434 provide a way to report various error conditions.
436 * ethdev: changed ``rte_eth_allmulticast_enable`` and
437 ``rte_eth_allmulticast_disable`` return value from ``void`` to ``int`` to
438 provide a way to report various error conditions.
440 * ethdev: changed ``rte_eth_dev_xstats_reset`` return value from ``void`` to
441 ``int`` to provide a way to report various error conditions.
443 * ethdev: changed ``rte_eth_link_get`` and ``rte_eth_link_get_nowait``
444 return value from ``void`` to ``int`` to provide a way to report various
447 * ethdev: changed ``rte_eth_macaddr_get`` return value from ``void`` to
448 ``int`` to provide a way to report various error conditions.
450 * ethdev: changed ``rte_eth_dev_owner_delete`` return value from ``void`` to
451 ``int`` to provide a way to report various error conditions.
453 * ethdev: The deprecated function ``rte_eth_dev_count`` was removed.
454 The function ``rte_eth_dev_count_avail`` is a drop-in replacement.
455 If the intent is to iterate over ports, ``RTE_ETH_FOREACH_*`` macros
456 are better port iterators.
458 * ethdev: RTE_FLOW_ITEM_TYPE_META data endianness altered to host one.
459 Due to the new dynamic metadata field in mbuf is host-endian either, there
460 is the minor compatibility issue for applications in case of 32-bit values
463 * ethdev: the tx_metadata mbuf field is moved to dymanic one.
464 PKT_TX_METADATA flag is replaced with PKT_TX_DYNF_METADATA.
465 DEV_TX_OFFLOAD_MATCH_METADATA offload flag is removed, now metadata
466 support in PMD is engaged on dynamic field registration.
468 * event: The function ``rte_event_eth_tx_adapter_enqueue`` takes an additional
469 input as ``flags``. Flag ``RTE_EVENT_ETH_TX_ADAPTER_ENQUEUE_SAME_DEST`` which
470 has been introduced in this release is used when used when all the packets
471 enqueued in the tx adapter are destined for the same Ethernet port & Tx queue.
473 * sched: The pipe nodes configuration parameters such as number of pipes,
474 pipe queue sizes, pipe profiles, etc., are moved from port level structure
475 to subport level. This allows different subports of the same port to
476 have different configuration for the pipe nodes.
482 .. This section should contain ABI changes. Sample format:
484 * sample: Add a short 1-2 sentence description of the ABI change
485 which was announced in the previous releases and made in this release.
486 Start with a scope label like "ethdev:".
487 Use fixed width quotes for ``function_names`` or ``struct_names``.
490 This section is a comment. Do not overwrite or remove it.
491 Also, make sure to start the actual text at the margin.
492 =========================================================
494 * policy: Please note the revisions to the :doc:`../contributing/abi_policy`
495 introducing major ABI versions, with DPDK 19.11 becoming the first major
496 version ``v20``. ABI changes to add new features continue to be permitted in
497 subsequent releases, with the condition that ABI compatibility with the major
498 ABI version is maintained.
500 * net: The Ethernet address and other header definitions have changed
501 attributes. They have been modified to be aligned on 2-byte boundaries.
502 These changes should not impact normal usage because drivers naturally
503 align the Ethernet header on receive and all known encapsulations
504 preserve the alignment of the header.
506 * security: The field ``replay_win_sz`` has been moved from ipsec library
507 based ``rte_ipsec_sa_prm`` structure to security library based structure
508 ``rte_security_ipsec_xform``, which specify the Anti replay window size
509 to enable sequence replay attack handling.
511 * ipsec: The field ``replay_win_sz`` has been removed from the structure
512 ``rte_ipsec_sa_prm`` as it has been added to the security library.
514 * ethdev: Added 32-bit fields for maximum LRO aggregated packet size, in
515 struct ``rte_eth_dev_info`` for the port capability and in struct
516 ``rte_eth_rxmode`` for the port configuration.
517 Application should use the new field in struct ``rte_eth_rxmode`` to configure
519 PMD should use the new field in struct ``rte_eth_dev_info`` to report the
520 supported port capability.
