449c49b93a
Until now, the objects stored in a mempool were internally stored in a ring. This patch introduces the possibility to register external handlers replacing the ring. The default behavior remains unchanged, but calling the new function rte_mempool_set_ops_byname() right after rte_mempool_create_empty() allows the user to change the handler that will be used when populating the mempool. This patch also adds a set of default ops (function callbacks) based on rte_ring.

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
|
|
-------------------
|
|
|
|
* The log history is deprecated.
|
|
It is voided in 16.07 and will be removed in release 16.11.
|
|
|
|
* 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.
|
|
|
|
* 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.
|
|
|
|
* 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]
|
|
|
|
* ABI will change for rte_mempool struct to move the cache-related fields
|
|
to the more appropriate rte_mempool_cache struct. The mempool API is
|
|
also changed to enable external cache management that is not tied to EAL
|
|
threads. Some mempool get and put calls are removed in favor of a more
|
|
compact API. The ones that remain are backwards compatible and use the
|
|
per-lcore default cache if available. This change targets release 16.07.
|
|
|
|
* 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.
