Deprecation Notices ------------------- -* 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. - -* ethdev: An API change is planned for 17.08 for the function - ``_rte_eth_dev_callback_process``. In 17.08 the function will return an ``int`` - instead of ``void`` and a fourth parameter ``void *ret_param`` will be added. - -* ethdev: for 17.08 it is planned to deprecate the following nine rte_eth_dev_* - functions and move them into the ixgbe PMD: - - ``rte_eth_dev_bypass_init``, ``rte_eth_dev_bypass_state_set``, - ``rte_eth_dev_bypass_state_show``, ``rte_eth_dev_bypass_event_store``, - ``rte_eth_dev_bypass_event_show``, ``rte_eth_dev_wd_timeout_store``, - ``rte_eth_dev_bypass_wd_timeout_show``, ``rte_eth_dev_bypass_ver_show``, - ``rte_eth_dev_bypass_wd_reset``. - - The following fields will be removed from ``struct eth_dev_ops``: - - ``bypass_init_t``, ``bypass_state_set_t``, ``bypass_state_show_t``, - ``bypass_event_set_t``, ``bypass_event_show_t``, ``bypass_wd_timeout_set_t``, - ``bypass_wd_timeout_show_t``, ``bypass_ver_show_t``, ``bypass_wd_reset_t``. - - The functions will be renamed to the following, and moved to the ``ixgbe`` PMD: - - ``rte_pmd_ixgbe_bypass_init``, ``rte_pmd_ixgbe_bypass_state_set``, - ``rte_pmd_ixgbe_bypass_state_show``, ``rte_pmd_ixgbe_bypass_event_set``, - ``rte_pmd_ixgbe_bypass_event_show``, ``rte_pmd_ixgbe_bypass_wd_timeout_set``, - ``rte_pmd_ixgbe_bypass_wd_timeout_show``, ``rte_pmd_ixgbe_bypass_ver_show``, - ``rte_pmd_ixgbe_bypass_wd_reset``. - -* 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 17.08. - 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. +* eal: DPDK runtime configuration file (located at + ``/var/run/._config``) will be moved. The new path will be as follows: + + - if DPDK is running as root, path will be set to + ``/var/run/dpdk//config`` + - if DPDK is not running as root and $XDG_RUNTIME_DIR is set, path will be set + to ``$XDG_RUNTIME_DIR/dpdk//config`` + - if DPDK is not running as root and $XDG_RUNTIME_DIR is not set, path will be + set to ``/tmp/dpdk//config`` + +* eal: both declaring and identifying devices will be streamlined in v18.05. + New functions will appear to query a specific port from buses, classes of + device and device drivers.
