9 .. **Read this first.**
11 The text in the sections below explains how to update the release notes.
13 Use proper spelling, capitalization and punctuation in all sections.
15 Variable and config names should be quoted as fixed width text:
18 Build the docs and view the output file to ensure the changes are correct::
21 xdg-open build/doc/html/guides/rel_notes/release_20_11.html
27 .. This section should contain new features added in this release.
30 * **Add a title in the past tense with a full stop.**
32 Add a short 1-2 sentence description in the past tense.
33 The description should be enough to allow someone scanning
34 the release notes to understand the new feature.
36 If the feature adds a lot of sub-features you can use a bullet list
39 * Added feature foo to do something.
40 * Enhanced feature bar to do something else.
42 Refer to the previous release notes for examples.
44 Suggested order in release notes items:
45 * Core libs (EAL, mempool, ring, mbuf, buses)
46 * Device abstraction libs and PMDs
48 - cryptodev (lib, PMDs)
49 - eventdev (lib, PMDs)
52 * Apps, Examples, Tools (if significant)

56 =======================================================
58 * **Extended flow-perf application.**
60 * Started supporting user order instead of bit mask:
61 Now the user can create any structure of rte_flow
62 using flow performance application with any order,
63 moreover the app also now starts to support inner
64 items matching as well.
70 .. This section should contain removed items in this release. Sample format:
72 * Add a short 1-2 sentence description of the removed item

76 Also, make sure to start the actual text at the margin.
77 =======================================================
83 .. This section should contain API changes. Sample format:
85 * sample: Add a short 1-2 sentence description of the API change
86 which was announced in the previous releases and made in this release.
87 Start with a scope label like "ethdev:".
88 Use fixed width quotes for ``function_names`` or ``struct_names``.

93 =======================================================
95 * eal: The ``rte_logs`` struct and global symbol was made private
96 and is no longer part of the API.
98 * eal: Made the ``rte_dev_event`` structure private to the EAL as no public API
101 * mem: Removed the unioned field ``phys_addr`` from
102 the structures ``rte_memseg`` and ``rte_memzone``.
103 The field ``iova`` is remaining from the old unions.
105 * mempool: Removed the unioned fields ``phys_addr`` and ``physaddr`` from
106 the structures ``rte_mempool_memhdr`` and ``rte_mempool_objhdr``.
107 The field ``iova`` is remaining from the old unions.
108 The flag name ``MEMPOOL_F_NO_PHYS_CONTIG`` is removed,
109 while the aliased flag ``MEMPOOL_F_NO_IOVA_CONTIG`` is kept.
111 * mbuf: Removed the functions ``rte_mbuf_data_dma_addr*``
112 and the macros ``rte_pktmbuf_mtophys*``.
113 The same functionality is still available with the functions and macros
114 having ``iova`` in their names instead of ``dma_addr`` or ``mtophys``.
116 * mbuf: Removed the unioned field ``buf_physaddr`` from ``rte_mbuf``.
117 The field ``buf_iova`` is remaining from the old union.
119 * mbuf: Removed the unioned field ``refcnt_atomic`` from
120 the structures ``rte_mbuf`` and ``rte_mbuf_ext_shared_info``.
121 The field ``refcnt`` is remaining from the old unions.
123 * pci: Removed the ``rte_kernel_driver`` enum defined in rte_dev.h and
124 replaced with a private enum in the PCI subsystem.
126 * pci: Removed the PCI resources map API from the public API
127 (``pci_map_resource`` and ``pci_unmap_resource``) and moved it to the
128 PCI bus driver along with the PCI resources lists and associated structures
129 (``pci_map``, ``pci_msix_table``, ``mapped_pci_resource`` and
130 ``mapped_pci_res_list``).
132 * ethdev: Removed the ``kdrv`` field in the ethdev ``rte_eth_dev_data``
133 structure as it gave no useful abstracted information to the applications.
135 * ethdev: ``rte_eth_rx_descriptor_done()`` API has been deprecated.
137 * Renamed internal ethdev APIs:
139 * ``_rte_eth_dev_callback_process()`` -> ``rte_eth_dev_callback_process()``
140 * ``_rte_eth_dev_reset`` -> ``rte_eth_dev_internal_reset()``
142 * rawdev: Added a structure size parameter to the functions
143 ``rte_rawdev_queue_setup()``, ``rte_rawdev_queue_conf_get()``,
144 ``rte_rawdev_info_get()`` and ``rte_rawdev_configure()``,
145 allowing limited driver type-checking and ABI compatibility.
147 * rawdev: Changed the return type of the function ``rte_dev_info_get()``
148 and the function ``rte_rawdev_queue_conf_get()``
149 from ``void`` to ``int`` allowing the return of error codes from drivers.
151 * bpf: ``RTE_BPF_XTYPE_NUM`` has been dropped from ``rte_bpf_xtype``.
157 .. This section should contain ABI changes. Sample format:
159 * sample: Add a short 1-2 sentence description of the ABI change
160 which was announced in the previous releases and made in this release.
161 Start with a scope label like "ethdev:".
162 Use fixed width quotes for ``function_names`` or ``struct_names``.

166 Also, make sure to start the actual text at the margin.
167 =======================================================
171 * Following device operation function pointers moved
172 from ``struct eth_dev_ops`` to ``struct rte_eth_dev``:
174 * ``eth_rx_queue_count_t rx_queue_count;``
175 * ``eth_rx_descriptor_done_t rx_descriptor_done;``
176 * ``eth_rx_descriptor_status_t rx_descriptor_status;``
177 * ``eth_tx_descriptor_status_t tx_descriptor_status;``
179 * ``struct eth_dev_ops`` is no more accessible by applications,
180 which was already internal data structure.
182 * ``ethdev`` internal functions are marked with ``__rte_internal`` tag.
188 .. This section should contain new known issues in this release. Sample format:
190 * **Add title in present tense with full stop.**
192 Add a short 1-2 sentence description of the known issue
193 in the present tense. Add information on any known workarounds.
195 This section is a comment. Do not overwrite or remove it.
196 Also, make sure to start the actual text at the margin.
197 =======================================================
203 .. This section should contain a list of platforms that were tested
208 * <vendor> platform with <vendor> <type of devices> combinations
213 * Other relevant details...
