Deprecation Notices
-------------------
-* ring: Changes are planned to rte_ring APIs in release 17.05. Proposed
- changes include:
-
- - Removing build time options for the ring:
- CONFIG_RTE_RING_SPLIT_PROD_CONS
- CONFIG_RTE_RING_PAUSE_REP_COUNT
- - Adding an additional parameter to enqueue functions to return the
- amount of free space in the ring
- - Adding an additional parameter to dequeue functions to return the
- number of remaining elements in the ring
- - Removing direct support for watermarks in the rings, since the
- additional return value from the enqueue function makes it
- unneeded
- - Adjusting the return values of the bulk() enq/deq functions to
- make them consistent with the burst() equivalents. [Note, parameter
- to these functions are changing too, per points above, so compiler
- will flag them as needing update in legacy code]
- - Updates to some library functions e.g. rte_ring_get_memsize() to
- allow for variably-sized ring elements.
+* eal: the following functions are deprecated starting from 17.05 and will
+ be removed in 17.08:
+
+ - ``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``
+
+* devargs: An ABI change is planned for 17.08 for the structure ``rte_devargs``.
+ The current version is dependent on bus-specific device identifier, which will
+ be made generic and abstracted, in order to make the EAL bus-agnostic.
+
+ Accompanying this evolution, device command line parameters will thus support
+ explicit bus definition in a device declaration.
* igb_uio: iomem mapping and sysfs files created for iomem and ioport in
igb_uio will be removed, because we are able to detect these from what Linux
has exposed, like the way we have done with uio-pci-generic. This change
targets release 17.05.
-* vfio: Some functions are planned to be exported outside librte_eal in 17.05.
- VFIO APIs like ``vfio_setup_device``, ``vfio_get_group_fd`` can be used by
- subsystem other than EAL/PCI. For that, these need to be exported symbols.
- Such APIs are planned to be renamed according to ``rte_*`` naming convention
- and exported from librte_eal.
+* The VDEV subsystem will be converted as driver of the new bus model.
+ It may imply some EAL API changes in 17.08.
-* The PCI and VDEV subsystems will be converted as drivers of the new bus model.
- It will imply some EAL API changes in 17.05.
+* The struct ``rte_pci_driver`` is planned to be removed from
+ ``rte_cryptodev_driver`` and ``rte_eventdev_driver`` in 17.08.
-* ``eth_driver`` is planned to be removed in 17.05. This currently serves as
- a placeholder for PMDs to register themselves. Changes for ``rte_bus`` will
- provide a way to handle device initialization currently being done in
- ``eth_driver``. Similarly, ``rte_pci_driver`` is planned to be removed from
- ``rte_cryptodev_driver`` in 17.05.
-
-* ethdev: An API change is planned for 17.05 for the function
- ``_rte_eth_dev_callback_process``. In 17.05 the function will return an ``int``
+* ethdev: An API change is planned for 17.08 for the function
+ ``_rte_eth_dev_callback_process``. In 17.08 the function will return an ``int``
instead of ``void`` and a fourth parameter ``void *ret_param`` will be added.
-* ethdev: for 17.05 it is planned to deprecate the following nine rte_eth_dev_*
+* ethdev: for 17.08 it is planned to deprecate the following nine rte_eth_dev_*
functions and move them into the ixgbe PMD:
``rte_eth_dev_bypass_init``, ``rte_eth_dev_bypass_state_set``,
``rte_pmd_ixgbe_bypass_wd_timeout_show``, ``rte_pmd_ixgbe_bypass_ver_show``,
``rte_pmd_ixgbe_bypass_wd_reset``.
-* ABI changes are planned for 17.05 in the ``rte_mbuf`` structure: some fields
- may be reordered to facilitate the writing of ``data_off``, ``refcnt``, and
- ``nb_segs`` in one operation, because some platforms have an overhead if the
- store address is not naturally aligned. Other mbuf fields, such as the
- ``port`` field, may be moved or removed as part of this mbuf work. A
- ``timestamp`` will also be added.
-
* 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 until 17.02 and will be removed in 17.05.
+ their behavior will be kept until 17.05 and will be removed in 17.08.
-* mempool: The functions ``rte_mempool_count`` and ``rte_mempool_free_count``
- will be removed in 17.05.
- They are replaced by ``rte_mempool_avail_count`` and
- ``rte_mempool_in_use_count`` respectively.
-
-* mempool: The functions for single/multi producer/consumer are deprecated
- and will be removed in 17.05.
- It is replaced by ``rte_mempool_generic_get/put`` functions.
+* ethdev: Tx offloads will no longer be enabled by default in 17.08.
+ 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
Target release for removal of the legacy API will be defined once most
PMDs have switched to rte_flow.
-* vhost: API/ABI changes are planned for 17.05, for making DPDK vhost library
- generic enough so that applications can build different vhost-user drivers
- (instead of vhost-user net only) on top of that.
- Specifically, ``virtio_net_device_ops`` will be renamed to ``vhost_device_ops``.
- Correspondingly, some API's parameter need be changed. Few more functions also
- need be reworked to let it be device aware. For example, different virtio device
- has different feature set, meaning functions like ``rte_vhost_feature_disable``
- need be changed. Last, file rte_virtio_net.h will be renamed to rte_vhost.h.
-
-* kni: Remove :ref:`kni_vhost_backend-label` feature (KNI_VHOST) in 17.05 release.
- :doc:`Vhost Library </prog_guide/vhost_lib>` is currently preferred method for
- guest - host communication. Just for clarification, this is not to remove KNI
- or VHOST feature, but KNI_VHOST which is a KNI feature enabled via a compile
- time option, and disabled by default.
-
-* ABI changes are planned for 17.05 in the ``rte_cryptodev_ops`` structure.
- A pointer to a rte_cryptodev_config structure will be added to the
- function prototype ``cryptodev_configure_t``, as a new parameter.
-
-* distributor: library API will be changed to incorporate a burst-oriented
- API. This will include a change to ``rte_distributor_create``
- to specify which type of instance to create (single or burst), and
- additional calls for ``rte_distributor_poll_pkt_burst`` and
- ``rte_distributor_return_pkt_burst``, among others.
-
-* The architecture TILE-Gx and the associated mpipe driver are not
- maintained and will be removed in 17.05.
+* cryptodev: All PMD names definitions will be moved to the individual PMDs
+ in 17.08.
+
+* cryptodev: The following changes will be done in in 17.08:
+
+ - the device type enumeration ``rte_cryptodev_type`` will be removed
+ - the following structures will be changed: ``rte_cryptodev_session``,
+ ``rte_cryptodev_sym_session``, ``rte_cryptodev_info``, ``rte_cryptodev``
+ - the function ``rte_cryptodev_count_devtype`` will be replaced by
+ ``rte_cryptodev_device_count_by_driver``
+
+* crypto/scheduler: the following two functions are deprecated starting
+ from 17.05 and will be removed in 17.08:
+
+ - ``rte_crpytodev_scheduler_mode_get``, replaced by ``rte_cryptodev_scheduler_mode_get``
+ - ``rte_crpytodev_scheduler_mode_set``, replaced by ``rte_cryptodev_scheduler_mode_set``
