- removal of ``name`` and ``args`` fields.
- The enum ``rte_devtype`` was used to identify a bus and will disappear.
- - The ``rte_devargs_list`` will be made private.
- Functions previously deprecated will change or disappear:
- + ``rte_eal_devargs_add``
+ ``rte_eal_devargs_type_count``
- + ``rte_eal_parse_devargs_str``, replaced by ``rte_eal_devargs_parse``
+ ``rte_eal_devargs_parse`` will change its format and use.
- + all ``rte_devargs`` related functions will be renamed, changing the
- ``rte_eal_devargs_`` prefix to ``rte_devargs_``.
* pci: Several exposed functions are misnamed.
The following functions are deprecated starting from v17.11 and are replaced:
- ``eal_parse_pci_DomBDF`` replaced by ``rte_pci_addr_parse``
- ``rte_eal_compare_pci_addr`` replaced by ``rte_pci_addr_cmp``
-* eal: The semantics of the return value for the ``rte_lcore_has_role`` function
- are planned to change in v18.05. The function currently returns 0 and <0 for
- success and failure, respectively. This will change to 1 and 0 for true and
- false, respectively, to make use of the function more intuitive.
-
* eal: a new set of mbuf mempool ops name APIs for user, platform and best
mempool names have been defined in ``rte_mbuf`` in v18.02. The uses of
``rte_eal_mbuf_default_mempool_ops`` shall be replaced by
- ``rte_eal_mbuf_default_mempool_ops``
* mempool: several API and ABI changes are planned in v18.05.
- The following functions, introduced for Xen, which is not supported
- anymore since v17.11, are hard to use, not used anywhere else in DPDK.
- Therefore they will be deprecated in v18.05 and removed in v18.08:
-
- - ``rte_mempool_xmem_create``
- - ``rte_mempool_xmem_size``
- - ``rte_mempool_xmem_usage``
The following changes are planned:
- - removal of ``get_capabilities`` mempool ops and related flags.
- - substitute ``register_memory_area`` with ``populate`` ops.
- - addition of new ops to customize required memory chunk calculation,
- customize objects population and allocate contiguous
+ - addition of new op to allocate contiguous
block of objects if underlying driver supports it.
* mbuf: The opaque ``mbuf->hash.sched`` field will be updated to support generic
director APIs. There is no ABI/API break. This change will just remove a
global configuration setting and require explicit configuration.
-* ring: The alignment constraints on the ring structure will be relaxed
- to one cache line instead of two, and an empty cache line padding will
- be added between the producer and consumer structures. The size of the
- structure and the offset of the fields will remain the same on
- platforms with 64B cache line, but will change on other platforms.
+* pdump: As we changed to use generic IPC, some changes in APIs and structure
+ are expected in subsequent release.
+
+ - ``rte_pdump_set_socket_dir`` will be removed;
+ - The parameter, ``path``, of ``rte_pdump_init`` will be removed;
+ - The enum ``rte_pdump_socktype`` will be removed.
