As announced in the previous release, The API to attach/dettach a session to a queue pair is removed, as it was only used in DPAA, and it is not actually needed. Signed-off-by: Pablo de Lara <pablo.de.lara.guarch@intel.com> Acked-by: Akhil Goyal <akhil.goyal@nxp.com>

ABI and API Deprecation
|

=======================
|
|
|
|
See the :doc:`guidelines document for details of the ABI policy </contributing/versioning>`.
|
|
API and ABI deprecation notices are to be posted here.

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 v18.08.
|
|
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
|
|
new scheme of device identification.
|
|
As such, ``rte_devargs`` device representation will change.
|
|
|
|
- The enum ``rte_devtype`` was used to identify a bus and will disappear.
|
|
- Functions previously deprecated will change or disappear:
|
|
|
|
+ ``rte_eal_devargs_type_count``
|
|
+ ``rte_eal_devargs_parse`` will change its format and use.
|
|
|
|
* pci: Several exposed functions are misnamed.
|
|
The following functions are deprecated starting from v17.11 and are replaced:
|
|
|
|
- ``eal_parse_pci_BDF`` replaced by ``rte_pci_addr_parse``
|
|
- ``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
|
|
will contain: queue ID, traffic class, color. Field size will not change.
|
|
|
|
* mbuf: the macro ``RTE_MBUF_INDIRECT()`` will be removed in v18.08 or later and
|
|
replaced with ``RTE_MBUF_CLONED()`` which is already added in v18.05. As
|
|
``EXT_ATTACHED_MBUF`` is newly introduced in v18.05, ``RTE_MBUF_INDIRECT()``
|
|
can no longer be mutually exclusive with ``RTE_MBUF_DIRECT()`` if the new
|
|
experimental API ``rte_pktmbuf_attach_extbuf()`` is used. Removal of the macro
|
|
is to fix this semantic inconsistency.
|
|
|
|
* ethdev: In v18.11 ``DEV_RX_OFFLOAD_CRC_STRIP`` offload flag will be removed, default
|
|
behavior without any flag will be changed to CRC strip.
|
|
To keep CRC ``DEV_RX_OFFLOAD_KEEP_CRC`` flag is required.
|
|
``KEEP_CRC``: Keep CRC in packet
|
|
No flag: Strip CRC from packet
|
|
|
|
* ethdev: the legacy filter API, including
|
|
``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well
|
|
as filter types MACVLAN, ETHERTYPE, FLEXIBLE, SYN, NTUPLE, TUNNEL, FDIR,
|
|
HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in
|
|
PMDs that implement the latter.
|
|
Target release for removal of the legacy API will be defined once most
|
|
PMDs have switched to rte_flow.
|
|
|
|
* 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.
