23 .. This section should contain new features added in this release. Sample
26 * **Add a title in the past tense with a full stop.**
28 Add a short 1-2 sentence description in the past tense. The description
29 should be enough to allow someone scanning the release notes to
30 understand the new feature.
32 If the feature adds a lot of sub-features you can use a bullet list like
35 * Added feature foo to do something.
36 * Enhanced feature bar to do something else.
38 Refer to the previous release notes for examples.

42 =========================================================
44 * **Extended port_id range from uint8_t to uint16_t.**
46 Increased port_id range from 8 bits to 16 bits in order to support more than
47 256 ports in dpdk. All ethdev APIs which have port_id as parameter are changed
50 * **nfp: Added PF support.**
52 Previously Netronome's NFP PMD had just support for VFs. PF support is
53 just as a basic DPDK port and has no VF management yet.
55 PF support comes with firmware upload support which allows the PMD to
56 independently work from kernel netdev NFP drivers.
58 NFP 4000 devices are also now supported along with previous 6000 devices.
60 * **Updated bnxt PMD.**
62 Major enhancements include:
64 * Support for Flow API
65 * Support for Tx and Rx descriptor status functions
67 * **Added IOMMU support to libvhost-user**
69 Implemented device IOTLB in Vhost-user backend, and enabled Virtio's IOMMU
72 * **Added Membership library (rte_member).**
74 Added membership library. It provides an API for DPDK applications to insert a
75 new member, delete an existing member, or query the existence of a member in a
76 given set, or a group of sets. For the case of a group of sets the library
77 will return not only whether the element has been inserted before in one of
78 the sets but also which set it belongs to.
80 The Membership Library is an extension and generalization of a traditional
81 filter (for example Bloom Filter) structure that has multiple usages in a wide
82 variety of workloads and applications. In general, the Membership Library is a
83 data structure that provides a “set-summary” and responds to set-membership
84 queries whether a certain member belongs to a set(s).
86 See the :ref:`Membership Library <Member_Library>` documentation in
87 the Programmers Guide document, for more information.
93 .. This section should contain bug fixes added to the relevant
94 sections. Sample format:
96 * **code/section Fixed issue in the past tense with a full stop.**
98 Add a short 1-2 sentence description of the resolved issue in the past
101 The title should contain the code/lib section like a commit message.

107 =========================================================
113 * **Service core fails to call service callback due to atomic lock**
115 In a specific configuration of multi-thread unsafe services and service
116 cores, a service core previously did not correctly release the atomic lock
117 on the service. This would result in the cores polling the service, but it
118 looked like another thread was executing the service callback. The logic for
119 atomic locking of the services has been fixed and refactored for readability.
140 .. This section should contain new known issues in this release. Sample format:
142 * **Add title in present tense with full stop.**
144 Add a short 1-2 sentence description of the known issue in the present
145 tense. Add information on any known workarounds.

163 =========================================================
165 * **Service cores API updated for usability**
167 The service cores API has been changed, removing pointers from the API
168 where possible, instead using integer IDs to identify each service. This
169 simplifed application code, aids debugging, and provides better
170 encapsulation. A summary of the main changes made is as follows:
172 * Services identified by ID not by ``rte_service_spec`` pointer
173 * Reduced API surface by using ``set`` functions instead of enable/disable
174 * Reworked ``rte_service_register`` to provide the service ID to registrar
175 * Rework start and stop APIs into ``rte_service_runstate_set``
176 * Added API to set runstate of service implementation to indicate readyness
178 * **The following changes made in mempool library**
180 * Moved ``flags`` datatype from int to unsigned int for ``rte_mempool``.
181 * Removed ``__rte_unused int flag`` param from ``rte_mempool_generic_put``
182 and ``rte_mempool_generic_get`` API.
183 * Added ``flags`` param in ``rte_mempool_xmem_size`` and
184 ``rte_mempool_xmem_usage``.
186 * Xen dom0 in EAL was removed, as well as xenvirt PMD and vhost_xen.
188 * ``rte_mem_phy2mch`` was used in Xen dom0 to obtain the physical address;
189 remove this API as Xen dom0 support was removed.
195 .. This section should contain ABI changes. Sample format:
197 * Add a short 1-2 sentence description of the ABI change that was announced
198 in the previous releases and made in this release. Use fixed width quotes
199 for ``rte_function_names`` or ``rte_struct_names``. Use the past tense.

203 =========================================================
205 * **Extended port_id range.**
207 The size of the field ``port_id`` in the ``rte_eth_dev_data`` structure
208 changed, as described in the `New Features` section.
