Deprecation Notices
-------------------
-* eal: DPDK runtime configuration file (located at
- ``/var/run/.<prefix>_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/<prefix>/config``
- - if DPDK is not running as root and $XDG_RUNTIME_DIR is set, path will be set
- to ``$XDG_RUNTIME_DIR/dpdk/<prefix>/config``
- - if DPDK is not running as root and $XDG_RUNTIME_DIR is not set, path will be
- set to ``/tmp/dpdk/<prefix>/config``
+* eal: certain structures will change in EAL on account of upcoming external
+ memory support. Aside from internal changes leading to an ABI break, the
+ following externally visible changes will also be implemented:
+
+ - ``rte_memseg_list`` will change to include a boolean flag indicating
+ whether a particular memseg list is externally allocated. This will have
+ implications for any users of memseg-walk-related functions, as they will
+ now have to skip externally allocated segments in most cases if the intent
+ is to only iterate over internal DPDK memory.
+ - ``socket_id`` parameter across the entire DPDK will gain additional meaning,
+ as some socket ID's will now be representing externally allocated memory. No
+ changes will be required for existing code as backwards compatibility will
+ be kept, and those who do not use this feature will not see these extra
+ socket ID's.
* eal: both declaring and identifying devices will be streamlined in v18.08.
New functions will appear to query a specific port from buses, classes of
- ``eal_parse_pci_DomBDF`` replaced by ``rte_pci_addr_parse``
- ``rte_eal_compare_pci_addr`` replaced by ``rte_pci_addr_cmp``
-* 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_mbuf_best_mempool_ops``.
- The following function is deprecated since 18.05, and will be removed
- in 18.08:
-
- - ``rte_eal_mbuf_default_mempool_ops``
-
* mbuf: The opaque ``mbuf->hash.sched`` field will be updated to support generic
definition in line with the ethdev TM and MTR APIs. Currently, this field
is defined in librte_sched in a non-generic way. The new generic format
Target release for removal of the legacy API will be defined once most
PMDs have switched to rte_flow.
+* ethdev: In v18.11 ``rte_eth_dev_attach()`` and ``rte_eth_dev_detach()``
+ will be removed.
+ Hotplug functions ``rte_eal_hotplug_add()`` and ``rte_eal_hotplug_remove()``
+ should be used instread.
+ Function ``rte_eth_dev_get_port_by_name()`` may be used to find
+ identifier of the added port.
+
+* eal: In v18.11 ``rte_eal_dev_attach()`` and ``rte_eal_dev_detach()``
+ will be removed.
+ Hotplug functions ``rte_eal_hotplug_add()`` and ``rte_eal_hotplug_remove()``
+ should be used directly.
+
* 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.
-
-* cryptodev: The following changes will be made in the library
- for 18.08:
-
- - Functions ``rte_cryptodev_queue_pair_attach_sym_session()`` and
- ``rte_cryptodev_queue_pair_dettach_sym_session()`` will be deprecated from
- 18.05 and removed in 18.08, as there are no drivers doing anything useful
- with them.
- - Some feature flags such as ``RTE_CRYPTODEV_FF_MBUF_SCATTER_GATHER`` are ambiguous,
- so some will be replaced by more explicit flags.
