Deprecation Notices
-------------------
-* The log history is deprecated.
- It is voided in 16.07 and will be removed in release 16.11.
+* eal: the following functions are deprecated starting from 17.05 and will
+ be removed in 17.11:
-* The ethdev hotplug API is going to be moved to EAL with a notification
- mechanism added to crypto and ethdev libraries so that hotplug is now
- available to both of them. This API will be stripped of the device arguments
- so that it only cares about hotplugging.
+ - ``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``
-* Structures embodying pci and vdev devices are going to be reworked to
- integrate new common rte_device / rte_driver objects (see
- http://dpdk.org/ml/archives/dev/2016-January/031390.html).
- ethdev and crypto libraries will then only handle those objects so that they
- do not need to care about the kind of devices that are being used, making it
- easier to add new buses later.
+* 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:
-* ABI changes are planned for adding four new flow types. This impacts
- RTE_ETH_FLOW_MAX. The release 2.2 does not contain these ABI changes,
- but release 2.3 will. [postponed]
+ - ``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.
* The mbuf flags PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated and
are respectively replaced by PKT_RX_VLAN_STRIPPED and
PKT_RX_QINQ_STRIPPED, that are better described. The old flags and
- their behavior will be kept in 16.07 and will be removed in 16.11.
+ their behavior will be kept until 17.08 and will be removed in 17.11.
+
+* mempool: The following will be modified in 17.11:
+
+ - ``rte_mempool_xmem_size`` and ``rte_mempool_xmem_usage`` need to know
+ the mempool flag status so adding new param rte_mempool in those API.
+ - Removing __rte_unused int flag param from ``rte_mempool_generic_put``
+ and ``rte_mempool_generic_get`` API.
+ - ``rte_mempool`` flags data type will changed from int to
+ unsigned int.
+
+* ethdev: Tx offloads will no longer be enabled by default in 17.11.
+ Instead, the ``rte_eth_txmode`` structure will be extended with
+ bit field to enable each Tx offload.
+ Besides of making the Rx/Tx configuration API more consistent for the
+ application, PMDs will be able to provide a better out of the box performance.
+ As part of the work, ``ETH_TXQ_FLAGS_NO*`` will be superseded as well.
+
+* 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.
+
+* ethdev: The device flag advertizing hotplug capability
+ ``RTE_ETH_DEV_DETACHABLE`` is not needed anymore and will be removed in
+ v17.11.
+ This capability is verified upon calling the relevant hotplug functions in EAL
+ by checking that the ``unplug`` ops is set in the bus. This verification is
+ done by the EAL and not by the ``ethdev`` layer anymore. Users relying on this
+ flag being present only have to remove their checks to follow the change.
+
+* ABI/API changes are planned for 17.11 in all structures which include port_id
+ definition such as "rte_eth_dev_data", "rte_port_ethdev_reader_params",
+ "rte_port_ethdev_writer_params", and so on. The definition of port_id will be
+ changed from 8 bits to 16 bits in order to support more than 256 ports in
+ DPDK. All APIs which have port_id parameter will be changed at the same time.
+
+* ethdev: An ABI change is planned for 17.11 for the structure rte_eth_dev_data.
+ The size of the unique name will increase RTE_ETH_NAME_MAX_LEN from 32 to
+ 64 characters to allow using a globally unique identifier (GUID) in this field.
+
+* ethdev: new parameters - ``rte_security_capabilities`` and
+ ``rte_security_ops`` will be added to ``rte_eth_dev_info`` and
+ ``rte_eth_dev`` respectively to support security operations like
+ ipsec inline.
+
+* cryptodev: new parameters - ``rte_security_capabilities`` and
+ ``rte_security_ops`` will be added to ``rte_cryptodev_info`` and
+ ``rte_cryptodev`` respectively to support security protocol offloaded
+ operations.
+
+* cryptodev: the following function is deprecated starting from 17.08 and will
+ be removed in 17.11:
+
+ - ``rte_cryptodev_create_vdev``
+
+* cryptodev: the following function will be static in 17.11 and included
+ by all crypto drivers, therefore, will not be public:
-* The APIs rte_mempool_count and rte_mempool_free_count are being deprecated
- on the basis that they are confusing to use - free_count actually returns
- the number of allocated entries, not the number of free entries as expected.
- They are being replaced by rte_mempool_avail_count and
- rte_mempool_in_use_count respectively.
+ - ``rte_cryptodev_vdev_pmd_init``
-* The mempool functions for single/multi producer/consumer are deprecated and
- will be removed in 16.11.
- It is replaced by rte_mempool_generic_get/put functions.
+* librte_table: The ``key_mask`` parameter will be added to all the hash tables
+ that currently do not have it, as well as to the hash compute function prototype.
+ The non-"do-sig" versions of the hash tables will be removed
+ (including the ``signature_offset`` parameter)
+ and the "do-sig" versions renamed accordingly.
