Deprecation Notices ------------------- -* igb_uio: iomem mapping and sysfs files created for iomem and ioport in - igb_uio will be removed, because we are able to detect these from what Linux - has exposed, like the way we have done with uio-pci-generic. This change - targets release 17.02. - -* ABI/API changes are planned for 17.02: ``rte_device``, ``rte_driver`` will be - impacted because of introduction of a new ``rte_bus`` hierarchy. This would - also impact the way devices are identified by EAL. A bus-device-driver model - will be introduced providing a hierarchical view of devices. - -* ``eth_driver`` is planned to be removed in 17.02. This currently serves as - a placeholder for PMDs to register themselves. Changes for ``rte_bus`` will - provide a way to handle device initialization currently being done in - ``eth_driver``. - -* In 17.02 ABI changes are planned: the ``rte_eth_dev`` structure will be - extended with new function pointer ``tx_pkt_prepare`` allowing verification - and processing of packet burst to meet HW specific requirements before - transmit. Also new fields will be added to the ``rte_eth_desc_lim`` structure: - ``nb_seg_max`` and ``nb_mtu_seg_max`` providing information about number of - segments limit to be transmitted by device for TSO/non-TSO packets. - -* ethdev: an API change is planned for 17.02 for the function - ``_rte_eth_dev_callback_process``. In 17.02 the function will return an ``int`` - instead of ``void`` and a fourth parameter ``void *ret_param`` will be added. - -* ethdev: for 17.02 it is planned to deprecate the following five functions - and move them in ixgbe: - - ``rte_eth_dev_set_vf_rxmode`` - - ``rte_eth_dev_set_vf_rx`` - - ``rte_eth_dev_set_vf_tx`` - - ``rte_eth_dev_set_vf_vlan_filter`` - - ``rte_eth_set_vf_rate_limit`` - -* ABI changes are planned for 17.02 in the ``rte_mbuf`` structure: some fields - may be reordered to facilitate the writing of ``data_off``, ``refcnt``, and - ``nb_segs`` in one operation, because some platforms have an overhead if the - store address is not naturally aligned. Other mbuf fields, such as the - ``port`` field, may be moved or removed as part of this mbuf work. A - ``timestamp`` will also be added. +* eal: the following functions are deprecated starting from 17.05 and will + be removed in 17.11: + + - ``rte_set_log_level``, replaced by ``rte_log_set_global_level`` + - ``rte_get_log_level``, replaced by ``rte_log_get_global_level`` + - ``rte_set_log_type``, replaced by ``rte_log_set_level`` + - ``rte_get_log_type``, replaced by ``rte_log_get_level`` + +* eal: several API and ABI changes are planned for ``rte_devargs`` in v17.11. + The format of device command line parameters will change. The bus will need + to be explicitly stated in the device declaration. The enum ``rte_devtype`` + was used to identify a bus and will disappear. + The structure ``rte_devargs`` will change. + The ``rte_devargs_list`` will be made private. + The following functions are deprecated starting from 17.08 and will either be + modified or removed in 17.11: + + - ``rte_eal_devargs_add`` + - ``rte_eal_devargs_type_count`` + - ``rte_eal_parse_devargs_str``, replaced by ``rte_eal_devargs_parse`` + +* eal: the support of Xen dom0 will be removed from EAL in 17.11; and with + that, drivers/net/xenvirt and examples/vhost_xen will also be removed. + +* eal: An ABI change is planned for 17.11 to make DPDK aware of IOVA address + translation scheme. + Reference to phys address in EAL data-structure or functions may change to + IOVA address or more appropriate name. + The change will be only for the name. + Functional aspects of the API or data-structure will remain same. * The mbuf flags PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated and are respectively replaced by PKT_RX_VLAN_STRIPPED and PKT_RX_QINQ_STRIPPED, that are better described. The old flags and - their behavior will be kept until 16.11 and will be removed in 17.02. - -* mempool: The functions ``rte_mempool_count`` and ``rte_mempool_free_count`` - will be removed in 17.02. - They are replaced by ``rte_mempool_avail_count`` and - ``rte_mempool_in_use_count`` respectively. - -* mempool: The functions for single/multi producer/consumer are deprecated - and will be removed in 17.02. - It is replaced by ``rte_mempool_generic_get/put`` functions. + their behavior will be kept until 17.08 and will be removed in 17.11. + +* ethdev: Tx offloads will no longer be enabled by default in 17.11. + Instead, the ``rte_eth_txmode`` structure will be extended with + bit field to enable each Tx offload. + Besides of making the Rx/Tx configuration API more consistent for the + application, PMDs will be able to provide a better out of the box performance. + As part of the work, ``ETH_TXQ_FLAGS_NO*`` will be superseded as well. + +* ethdev: the legacy filter API, including + ``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well + as filter types MACVLAN, ETHERTYPE, FLEXIBLE, SYN, NTUPLE, TUNNEL, FDIR, + HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in + PMDs that implement the latter. + Target release for removal of the legacy API will be defined once most + PMDs have switched to rte_flow. + +* librte_table: The ``key_mask`` parameter will be added to all the hash tables + that currently do not have it, as well as to the hash compute function prototype. + The non-"do-sig" versions of the hash tables will be removed + (including the ``signature_offset`` parameter) + and the "do-sig" versions renamed accordingly. + +* cryptodev: the following function is deprecated starting from 17.08 and will + be removed in 17.11: + + - ``rte_cryptodev_create_vdev``
