Deprecation Notices ------------------- -* The EAL function pci_config_space_set is deprecated in release 16.04 - and will be removed from 16.07. - Macros CONFIG_RTE_PCI_CONFIG, CONFIG_RTE_PCI_EXTENDED_TAG and - CONFIG_RTE_PCI_MAX_READ_REQUEST_SIZE will be removed. - The /sys entries extended_tag and max_read_request_size created by igb_uio - will be removed. - -* ABI changes are planned for struct rte_pci_id, i.e., add new field ``class``. - This new added ``class`` field can be used to probe pci device by class - related info. This change should impact size of struct rte_pci_id and struct - rte_pci_device. The release 16.04 does not contain these ABI changes, but - release 16.07 will. - -* The following fields have been deprecated in rte_eth_stats: - ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss, - tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff - -* The xstats API and rte_eth_xstats struct will be changed to allow retrieval - of values without any string copies or parsing. - No backwards compatibility is planned, as it would require code duplication - in every PMD that supports xstats. - -* ABI changes are planned for adding four new flow types. This impacts - RTE_ETH_FLOW_MAX. The release 2.2 does not contain these ABI changes, - but release 2.3 will. [postponed] - -* ABI change is planned for the rte_mempool structure to allow mempool - cache support to be dynamic depending on the mempool being created - needing cache support. Saves about 1.5M of memory per rte_mempool structure - by removing the per lcore cache memory. Change will occur in DPDK 16.07 - release and will skip the define RTE_NEXT_ABI in DPDK 16.04 release. The - code affected is app/test/test_mempool.c and librte_mempool/rte_mempool.[ch]. - The rte_mempool.local_cache will be converted from an array to a pointer to - allow for dynamic allocation of the per lcore cache memory. - -* The rte_mempool struct will be changed in 16.07 to facilitate the new - external mempool manager functionality. - The ring element will be replaced with a more generic 'pool' opaque pointer - to allow new mempool handlers to use their own user-defined mempool - layout. Also newly added to rte_mempool is a handler index. - The existing API will be backward compatible, but there will be new API - functions added to facilitate the creation of mempools using an external - handler. The 16.07 release will contain these changes. - -* The rte_mempool allocation will be changed in 16.07: - allocation of large mempool in several virtual memory chunks, new API - to populate a mempool, new API to free a mempool, allocation in - anonymous mapping, drop of specific dom0 code. These changes will - induce a modification of the rte_mempool structure, plus a - modification of the API of rte_mempool_obj_iter(), implying a breakage - of the ABI. - -* ABI changes are planned for struct rte_port_source_params in order to - support PCAP file reading feature. The release 16.04 contains this ABI - change wrapped by RTE_NEXT_ABI macro. Release 16.07 will contain this - change, and no backwards compatibility is planned. +* eal: the following functions are deprecated starting from 17.05 and will + be removed in 17.08: + + - ``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`` + +* devargs: An ABI change is planned for 17.08 for the structure ``rte_devargs``. + The current version is dependent on bus-specific device identifier, which will + be made generic and abstracted, in order to make the EAL bus-agnostic. + + Accompanying this evolution, device command line parameters will thus support + explicit bus definition in a device declaration. + +* 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 17.05. + +* The VDEV subsystem will be converted as driver of the new bus model. + It may imply some EAL API changes in 17.08. + +* The struct ``rte_pci_driver`` is planned to be removed from + ``rte_cryptodev_driver`` and ``rte_eventdev_driver`` in 17.08. + +* 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 17.05 and will be removed in 17.08. + +* 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. + +* eal: the following function is deprecated starting from 17.08 and will + be removed in 17.11: + + - ``rte_eal_parse_devargs_str``, replaced by ``rte_eal_devargs_parse`` + +* cryptodev: the following function is deprecated starting from 17.08 and will + be removed in 17.11: + + - ``rte_cryptodev_create_vdev``
