12 * **Added write combining store APIs.**
14 Added ``rte_write32_wc`` and ``rte_write32_wc_relaxed`` APIs
15 that enable write combining stores (depending on architecture).
16 The functions are provided as a generic stub and
17 x86 specific implementation.
19 * **Added prefetch with intention to write APIs.**
21 Added new prefetch function variants e.g. ``rte_prefetch0_write``,
22 which allow the programmer to prefetch a cache line and also indicate
23 the intention to write.
25 * **Added the rte_cldemote API.**
27 Added a hardware hint CLDEMOTE, which is similar to prefetch in reverse.
28 CLDEMOTE moves the cache line to the more remote cache, where it expects
29 sharing to be efficient. Moving the cache line to a level more distant from
30 the processor helps to accelerate core-to-core communication.
31 This API is specific to x86 and implemented as a stub for other
34 * **Added support for limiting maximum SIMD bitwidth.**
36 Added a new EAL config setting ``max_simd_bitwidth`` to limit the vector
37 path selection at runtime. This value can be set by apps using the
38 ``rte_vect_set_max_simd_bitwidth`` function, or by the user with EAL flag
39 ``--force-max-simd-bitwidth``.
41 * **Added zero copy APIs for rte_ring.**
43 For rings with producer/consumer in ``RTE_RING_SYNC_ST``, ``RTE_RING_SYNC_MT_HTS``
44 modes, these APIs split enqueue/dequeue operation into three phases
45 (enqueue/dequeue start, copy data to/from ring, enqueue/dequeue finish).
46 Along with the advantages of the peek APIs, these provide the ability to
47 copy the data to the ring memory directly without the need for temporary
50 * **Updated CRC modules of the net library.**
52 * Added runtime selection of the optimal architecture-specific CRC path.
53 * Added optimized implementations of CRC32-Ethernet and CRC16-CCITT
54 using the AVX512 and VPCLMULQDQ instruction sets.

69 Added the ``RTE_ETH_DEV_FLOW_OPS_THREAD_SAFE`` device flag to indicate
70 whether a PMD supports thread safe operations. If the PMD doesn't set the flag,
71 the rte_flow API level functions will protect the flow operations with a mutex.
73 * **Added flow-based traffic sampling support.**
75 Added a new action ``RTE_FLOW_ACTION_TYPE_SAMPLE`` that will sample the
76 incoming traffic and send a duplicated traffic with the specified ratio to
77 the application, while the original packet will continue to the target
80 The packets sampling is '1/ratio'. A ratio value set to 1 means that the
81 packets will be completely mirrored. The sample packet can be assigned with
82 a different set of actions than the original packet.
84 * **Added support of shared action in flow API.**
86 Added shared action support to use single flow actions in multiple flow
87 rules. An update to the shared action configuration alters the behavior of all
90 * Added a new action: ``RTE_FLOW_ACTION_TYPE_SHARED`` to use shared action
92 * Added new flow APIs to create/update/destroy/query shared actions.
94 * **Added support to flow rules to allow private PMD items/actions.**
96 * Flow rule verification has been updated to accept private PMD

101 * Added a new hardware independent helper to the flow API that
102 offloads tunneled traffic and restores missed packets.
104 * **Updated the ethdev library to support hairpin between two ports.**
106 New APIs have been introduced to support binding / unbinding of 2 ports in a
107 hairpin configuration. The hairpin Tx part flow rules can be inserted
108 explicitly. A new API has been added to get the hairpin peer ports list.

320 <https://01.org/blogs/2019/introducing-intel-data-streaming-accelerator>`_.
321 * Added support for the fill operation via the API ``rte_ioat_enqueue_fill()``,
322 where the hardware fills an area of memory with a repeating pattern.
323 * Added a per-device configuration flag to disable management
324 of user-provided completion handles.
325 * Renamed the ``rte_ioat_do_copies()`` API to ``rte_ioat_perform_ops()``,
326 and renamed the ``rte_ioat_completed_copies()`` API to ``rte_ioat_completed_ops()``
327 to better reflect the APIs' purposes, and remove the implication that
328 they are limited to copy operations only.
329 Note: The old API is still provided but marked as deprecated in the code.
330 * Added a new API ``rte_ioat_fence()`` to add a fence between operations.
331 This API replaces the ``fence`` flag parameter in the ``rte_ioat_enqueue_copies()`` function,
332 and is clearer as there is no ambiguity as to whether the flag should be
333 set on the last operation before the fence or the first operation after it.
335 * **Updated the pipeline library for alignment with the P4 language.**
337 Added a new Software Switch (SWX) pipeline type that provides more
338 flexibility through APIs and feature alignment with the P4 language.

359 * **Added support to update subport bandwidth dynamically.**
361 * Added new API ``rte_sched_port_subport_profile_add`` to add new
362 subport bandwidth profiles to the subport profile table at runtime.
364 * Added support to update the subport rate dynamically.
366 * **Updated FIPS validation sample application.**
368 * Added scatter gather support.
369 * Added NIST GCMVS complaint GMAC test method support.
371 * **Updated l3wfd-acl sample application.**
373 * Added new optional parameter ``--eth-dest`` for the ``l3fwd-acl`` to allow
374 the user to specify the destination mac address for each ethernet port
376 * Replaced ``--scalar`` command-line option with ``--alg=<value>``, to allow
377 the user to select the desired classify method.
379 * **Updated vhost sample application.**
381 Added vhost asynchronous APIs support, which demonstrates how the application
382 can leverage IOAT DMA channels with vhost asynchronous APIs.
383 See the :doc:`../sample_app_ug/vhost` for more details.
389 * build: Support for the Make build system has been removed from DPDK.
390 Meson is now the primary build system.
391 Sample applications can still be built with Make standalone, using pkg-config.
393 * vhost: Dequeue zero-copy support has been removed.
395 * kernel: The module ``igb_uio`` has been moved to the git repository
396 `dpdk-kmods <https://git.dpdk.org/dpdk-kmods/>`_ in a new directory

411 The information provided by these macros is now available through standard
414 * eal: Replaced the function ``rte_get_master_lcore()`` with
415 ``rte_get_main_lcore()``. The old function is deprecated.
417 The iterator for worker lcores is also changed:
418 ``RTE_LCORE_FOREACH_SLAVE`` is replaced with
419 ``RTE_LCORE_FOREACH_WORKER``.
421 * eal: The definitions related to including and excluding devices
422 have been changed from blacklist/whitelist to block/allow list.
423 There are compatibility macros and command line mapping to accept
424 the old values but applications and scripts are strongly encouraged
425 to migrate to the new names.
427 * eal: The ``rte_logs`` struct and global symbol was made private
428 and is no longer part of the API.
430 * eal: Made the ``rte_dev_event`` structure private to the EAL as no public API
433 * eal: ``rte_cio_rmb()`` and ``rte_cio_wmb()`` were deprecated since 20.08
434 and are removed in this release.
436 * mem: Removed the unioned field ``phys_addr`` from
437 the structures ``rte_memseg`` and ``rte_memzone``.
438 The field ``iova`` remains from the old unions.
440 * mempool: Removed the unioned fields ``phys_addr`` and ``physaddr`` from
441 the structures ``rte_mempool_memhdr`` and ``rte_mempool_objhdr``.
442 The field ``iova`` remains from the old unions.
443 The flag name ``MEMPOOL_F_NO_PHYS_CONTIG`` is removed,
444 while the aliased flag ``MEMPOOL_F_NO_IOVA_CONTIG`` is kept.
446 * mbuf: Removed the functions ``rte_mbuf_data_dma_addr*``
447 and the macros ``rte_pktmbuf_mtophys*``.
448 The same functionality is still available with the functions and macros
449 having ``iova`` in their names instead of ``dma_addr`` or ``mtophys``.
451 * mbuf: Removed the unioned field ``buf_physaddr`` from ``rte_mbuf``.
452 The field ``buf_iova`` remains from the old union.
454 * mbuf: Removed the unioned field ``refcnt_atomic`` from
455 the structures ``rte_mbuf`` and ``rte_mbuf_ext_shared_info``.
456 The field ``refcnt`` remains from the old unions.
458 * mbuf: Removed the unioned fields ``userdata`` and ``udata64``
459 from the structure ``rte_mbuf``. It is replaced with dynamic fields.
461 * mbuf: Removed the field ``seqn`` from the structure ``rte_mbuf``.
462 It is replaced with dynamic fields.
464 * mbuf: Removed the field ``timestamp`` from the structure ``rte_mbuf``.
465 It is replaced with the dynamic field RTE_MBUF_DYNFIELD_TIMESTAMP_NAME
466 which was previously used only for Tx.
468 * pci: Removed the ``rte_kernel_driver`` enum defined in rte_dev.h and
469 replaced with a private enum in the PCI subsystem.
471 * pci: Removed the PCI resources map API from the public API
472 (``pci_map_resource`` and ``pci_unmap_resource``) and moved it to the
473 PCI bus driver along with the PCI resources lists and associated structures
474 (``pci_map``, ``pci_msix_table``, ``mapped_pci_resource`` and
475 ``mapped_pci_res_list``).
477 * ethdev: Removed the ``kdrv`` field in the ethdev ``rte_eth_dev_data``
478 structure as it gave no useful abstracted information to the applications.
480 * ethdev: ``rte_eth_rx_descriptor_done()`` API has been deprecated.
482 * ethdev: Renamed basic statistics per queue. An underscore is inserted
483 between the queue number and the rest of the xstat name:
485 * ``rx_qN*`` -> ``rx_qN_*``
486 * ``tx_qN*`` -> ``tx_qN_*``
488 * ethdev: Added capability to query age flow action.
490 * ethdev: Changed ``rte_eth_dev_stop`` return value from ``void`` to
491 ``int`` to provide a way to report various error conditions.
493 * ethdev: Added ``int`` return type to ``rte_eth_dev_close()``.
495 * ethdev: Renamed internal functions:
497 * ``_rte_eth_dev_callback_process()`` -> ``rte_eth_dev_callback_process()``
498 * ``_rte_eth_dev_reset`` -> ``rte_eth_dev_internal_reset()``
500 * ethdev: Modified field type of ``base`` and ``nb_queue`` in struct
501 ``rte_eth_dcb_tc_queue_mapping`` from ``uint8_t`` to ``uint16_t``.
502 As the data of ``uint8_t`` will be truncated when queue number in
503 a TC is greater than 256.
505 * ethdev: Removed the legacy filter API, including
506 ``rte_eth_dev_filter_supported()`` and ``rte_eth_dev_filter_ctrl()``.
508 * ethdev: Removed the legacy L2 tunnel configuration API, including
509 ``rte_eth_dev_l2_tunnel_eth_type_conf()`` and
510 ``rte_eth_dev_l2_tunnel_offload_set()``..
512 * vhost: Moved vDPA APIs from experimental to stable.
514 * vhost: Add a new function ``rte_vhost_crypto_driver_start`` to be called
515 instead of ``rte_vhost_driver_start`` by crypto applications.
517 * cryptodev: The structure ``rte_crypto_sym_vec`` is updated to support both
518 cpu_crypto synchronous operations and asynchronous raw data-path APIs.
520 * cryptodev: ``RTE_CRYPTO_AEAD_LIST_END`` from ``enum rte_crypto_aead_algorithm``,
521 ``RTE_CRYPTO_CIPHER_LIST_END`` from ``enum rte_crypto_cipher_algorithm`` and
522 ``RTE_CRYPTO_AUTH_LIST_END`` from ``enum rte_crypto_auth_algorithm``
523 are removed to avoid future ABI breakage while adding new algorithms.
525 * scheduler: Renamed functions ``rte_cryptodev_scheduler_slave_attach``,
526 ``rte_cryptodev_scheduler_slave_detach`` and
527 ``rte_cryptodev_scheduler_slaves_get`` to
528 ``rte_cryptodev_scheduler_worker_attach``,
529 ``rte_cryptodev_scheduler_worker_detach`` and
530 ``rte_cryptodev_scheduler_workers_get`` accordingly.
532 * scheduler: Renamed the configuration value
533 ``RTE_CRYPTODEV_SCHEDULER_MAX_NB_SLAVES`` to
534 ``RTE_CRYPTODEV_SCHEDULER_MAX_NB_WORKERS``.
536 * security: The ``hfn_ovrd`` field in ``rte_security_pdcp_xform`` is changed from
537 ``uint32_t`` to ``uint8_t`` so that a new field ``sdap_enabled`` can be added
540 * security: The API ``rte_security_session_create`` is updated to take two
541 mempool objects: one for session and other for session private data.
542 So the application need to create two mempools and get the size of session
543 private data using API ``rte_security_session_get_size`` for private session
546 * ipsec: ``RTE_SATP_LOG2_NUM`` has been dropped from ``enum`` and
547 subsequently moved ``rte_ipsec`` lib from experimental to stable.
549 * baseband/fpga_lte_fec: Renamed function ``fpga_lte_fec_configure`` to
550 ``rte_fpga_lte_fec_configure`` and structure ``fpga_lte_fec_conf`` to
551 ``rte_fpga_lte_fec_conf``.
553 * baseband/fpga_5gnr_fec: Renamed function ``fpga_5gnr_fec_configure`` to
554 ``rte_fpga_5gnr_fec_configure`` and structure ``fpga_5gnr_fec_conf`` to
555 ``rte_fpga_5gnr_fec_conf``.
557 * rawdev: Added a structure size parameter to the functions
558 ``rte_rawdev_queue_setup()``, ``rte_rawdev_queue_conf_get()``,
559 ``rte_rawdev_info_get()`` and ``rte_rawdev_configure()``,
560 allowing limited driver type-checking and ABI compatibility.
562 * rawdev: Changed the return type of the function ``rte_dev_info_get()``
563 and the function ``rte_rawdev_queue_conf_get()``
564 from ``void`` to ``int`` allowing the return of error codes from drivers.
566 * rawdev: The running of a drivers ``selftest()`` function can now be done
567 using the ``rawdev_autotest`` command in the ``dpdk-test`` binary. This
568 command now calls the self-test function for each rawdev found on the
569 system, and does not require a specific command per device type.
570 Following this change, the ``ioat_rawdev_autotest`` command has been
571 removed as no longer needed.
573 * raw/ioat: As noted above, the ``rte_ioat_do_copies()`` and
574 ``rte_ioat_completed_copies()`` functions have been renamed to
575 ``rte_ioat_perform_ops()`` and ``rte_ioat_completed_ops()`` respectively.
577 * stack: the experimental tag has been dropped from the stack library, and its
578 interfaces are considered stable as of DPDK 20.11.
580 * bpf: ``RTE_BPF_XTYPE_NUM`` has been dropped from ``rte_bpf_xtype``.
582 * gso: Changed ``rte_gso_segment`` behaviour and return value:
584 * ``pkt`` is not saved to ``pkts_out[0]`` if not GSOed.
585 * Return 0 instead of 1 for the above case.
586 * ``pkt`` is not freed, no matter whether it is GSOed, leaving to the caller.
588 * acl: ``RTE_ACL_CLASSIFY_NUM`` enum value has been removed.
589 This enum value was not used inside DPDK, while it prevented the addition of new
590 classify algorithms without causing an ABI breakage.
592 * sched: Added ``subport_profile_id`` as an argument
593 to function ``rte_sched_subport_config``.
595 * sched: Removed ``tb_rate``, ``tc_rate``, ``tc_period`` and ``tb_size``
596 from ``struct rte_sched_subport_params``.
602 * eal: Removed the unimplemented function ``rte_dump_registers()``.
606 * The following device operation function pointers moved
607 from ``struct eth_dev_ops`` to ``struct rte_eth_dev``:
609 * ``eth_rx_queue_count_t rx_queue_count;``
610 * ``eth_rx_descriptor_done_t rx_descriptor_done;``
611 * ``eth_rx_descriptor_status_t rx_descriptor_status;``
612 * ``eth_tx_descriptor_status_t tx_descriptor_status;``
614 * ``struct eth_dev_ops`` is no longer accessible by applications,
615 which was already an internal data structure.
617 * ``ethdev`` internal functions are marked with ``__rte_internal`` tag.
619 * Added extensions' attributes to struct ``rte_flow_item_ipv6``.
620 A set of additional values added to struct, indicating the existence of
621 every defined extension header type.
622 Applications should use the new values for identification of existing
623 extensions in the packet header.
625 * Added fields ``rx_seg`` and ``rx_nseg`` to ``rte_eth_rxconf`` structure
626 to provide extended description of the receiving buffer.
628 * ``struct rte_eth_hairpin_conf`` has two new members:
630 * ``uint32_t tx_explicit:1;``
631 * ``uint32_t manual_bind:1;``
633 * Added new field ``has_vlan`` to structure ``rte_flow_item_eth``,
634 indicating that packet header contains at least one VLAN.
636 * Added new field ``has_more_vlan`` to the structure
637 ``rte_flow_item_vlan``, indicating that packet header contains
638 at least one more VLAN, after this VLAN.
640 * eventdev: The following structures are modified to support DLB/DLB2 PMDs
641 and future extensions:
643 * ``rte_event_dev_info``
644 * ``rte_event_dev_config``
645 * ``rte_event_port_conf``
647 * sched: Added new fields to ``struct rte_sched_subport_port_params``.
649 * lpm: Removed fields other than ``tbl24`` and ``tbl8`` from the struct
650 ``rte_lpm``. The removed fields were made internal.
