-* ring: Changes are planned to rte_ring APIs in release 17.05. Proposed
- changes include:
-
- - Removing build time options for the ring:
- CONFIG_RTE_RING_SPLIT_PROD_CONS
- CONFIG_RTE_RING_PAUSE_REP_COUNT
- - Adding an additional parameter to enqueue functions to return the
- amount of free space in the ring
- - Adding an additional parameter to dequeue functions to return the
- number of remaining elements in the ring
- - Removing direct support for watermarks in the rings, since the
- additional return value from the enqueue function makes it
- unneeded
- - Adjusting the return values of the bulk() enq/deq functions to
- make them consistent with the burst() equivalents. [Note, parameter
- to these functions are changing too, per points above, so compiler
- will flag them as needing update in legacy code]
- - Updates to some library functions e.g. rte_ring_get_memsize() to
- allow for variably-sized ring elements.
-
-* 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.
-
-* vfio: Some functions are planned to be exported outside librte_eal in 17.05.
- VFIO APIs like ``vfio_setup_device``, ``vfio_get_group_fd`` can be used by
- subsystem other than EAL/PCI. For that, these need to be exported symbols.
- Such APIs are planned to be renamed according to ``rte_*`` naming convention
- and exported from librte_eal.
-
-* The PCI and VDEV subsystems will be converted as drivers of the new bus model.
- It will imply some EAL API changes in 17.05.
-
-* ``eth_driver`` is planned to be removed in 17.05. 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``. Similarly, ``rte_pci_driver`` is planned to be removed from
- ``rte_cryptodev_driver`` in 17.05.
-
-* ethdev: An API change is planned for 17.05 for the function
- ``_rte_eth_dev_callback_process``. In 17.05 the function will return an ``int``
- instead of ``void`` and a fourth parameter ``void *ret_param`` will be added.
-
-* ethdev: for 17.05 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``.
-
-* ABI changes are planned for 17.05 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.
