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: 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. Device declaration will be made coherent with the
- The enum ``rte_devtype`` was used to identify a bus and will disappear.
- 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_mbuf_best_mempool_ops``.
- The following function is now redundant and it is target to be deprecated
- in 18.05:
+ The following function is deprecated since 18.05, and will be removed
+ in 18.08:
- ``rte_eal_mbuf_default_mempool_ops``
-* mempool: several API and ABI changes are planned in v18.05.
-
- The following changes are planned:
-
- - 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
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
In the new API, offloads are divided into per-port and per-queue offloads.
Offloads are disabled by default and enabled per application request.
- The old ethdev - drivers offload interface will be deprecated on 18.05.
- This includes:
- - removal of the conversion in ethdev from new offloading API to old API for drivers.
-
In later releases the old offloading API will be deprecated, which will include:
- removal of ``ETH_TXQ_FLAGS_NO*`` flags.
- removal of ``txq_flags`` field from ``rte_eth_txconf`` struct.
Target release for removal of the legacy API will be defined once most
PMDs have switched to rte_flow.
-* ethdev: A new rss level field planned in 18.05.
- The new API add rss_level field to ``rte_eth_rss_conf`` to enable a choice
- of RSS hash calculation on outer or inner header of tunneled packet.
-
-* ethdev: A work is being planned for 18.05 to expose VF port representors
- as a mean to perform control and data path operation on the different VFs.
- As VF representor is an ethdev port, new fields are needed in order to map
- between the VF representor and the VF or the parent PF. Those new fields
- are to be included in ``rte_eth_dev_info`` struct.
-
-* i40e: The default flexible payload configuration which extracts the first 16
- bytes of the payload for RSS will be deprecated starting from 18.02. If
- required the previous behavior can be configured using existing flow
- director APIs. There is no ABI/API break. This change will just remove a
- global configuration setting and require explicit configuration.
-
* 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:
+
+ - Removal of ``sym`` structure in ``rte_cryptodev_info`` structure,
+ containing fields not relevant anymore since the session mempool
+ is not internal in the crypto device anymore.
+ - Replacement of ``pci_dev`` field with the more generic ``rte_device``
+ structure.
+ - 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.
+ - Functions ``rte_cryptodev_queue_pair_start()`` and
+ ``rte_cryptodev_queue_pair_stop()`` 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.
+ - Function ``rte_cryptodev_get_header_session_size()`` will be deprecated
+ in 18.05, and it gets replaced with ``rte_cryptodev_sym_get_header_session_size()``.
+ It will be removed in 18.08.
+ - Function ``rte_cryptodev_get_private_session_size()`` will be deprecated
+ in 18.05, and it gets replaced with ``rte_cryptodev_sym_get_private_session_size()``.
+ It will be removed in 18.08.
