56 =======================================================
58 * **Added auxiliary bus support.**
60 An auxiliary bus provides a way to split a function into child-devices
61 representing sub-domains of functionality. Each auxiliary device
62 represents a part of its parent functionality.
64 * **Added XZ compressed firmware support.**
66 Using ``rte_firmware_read`` a driver can now handle XZ compressed firmware
67 in a transparent way, with EAL uncompressing using libarchive, if this library
68 is available when building DPDK.
70 * **Updated Amazon ENA PMD.**
72 Updated the Amazon ENA PMD. The new driver version (v2.4.0) introduced
73 bug fixes and improvements, including:
75 * Added Rx interrupt support.
76 * RSS hash function key reconfiguration support.
78 * **Updated Intel iavf driver.**
80 * Added Tx QoS VF queue TC mapping.
81 * Added FDIR and RSS for GTPoGRE, and support for filters based on GTPU TEID/QFI,
82 outermost L3 or innermost L3/L4.
84 * **Updated Intel ice driver.**
86 * Added new RX and TX paths in the AVX2 code to use HW offload
87 features. When the HW offload features are configured to be used, the
88 offload paths are chosen automatically. In parallel the support for HW
89 offload features was removed from the legacy AVX2 paths.
90 * Added Tx QoS TC bandwidth configuration in DCF.
92 * **Added support for Marvell CN10K SoC Ethernet device.**
94 * Added net/cnxk driver which provides the support for the integrated Ethernet
97 * **Updated Mellanox mlx5 driver.**
99 * Added Sub-Function support based on auxiliary bus.
100 * Added support for meter hierarchy.
101 * Added support for metering policy actions of yellow color.
102 * Added support for metering trTCM RFC2698 and RFC4115.
103 * Added devargs option ``allow_duplicate_pattern``.
104 * Added matching on IPv4 Internet Header Length (IHL).
105 * Added support for matching on VXLAN header last 8-bits reserved field.
106 * Optimized multi-thread flow rule insertion rate.
108 * **Updated Solarflare network PMD.**
110 Updated the Solarflare ``sfc_efx`` driver with changes including:
112 * Added COUNT action support for SN1000 NICs.
114 * **Added Wangxun ngbe PMD.**
116 Added a new PMD driver for Wangxun 1Gb Ethernet NICs.
117 See the :doc:`../nics/ngbe` for more details.
119 * **Added inflight packets clear API in vhost library.**
121 Added an API which can clear the inflight packets submitted to
122 the DMA engine in the vhost async data path.
124 * **Updated Intel QuickAssist crypto PMD.**
126 Added fourth generation of QuickAssist Technology(QAT) devices support.
127 Only symmetric crypto has been currently enabled. Compression and asymmetric
128 crypto PMD will fail to create.
130 * **Added support for Marvell CNXK crypto driver.**
132 * Added cnxk crypto PMD which provides support for an integrated
133 crypto driver for CN9K and CN10K series of SOCs. Support for
134 symmetric crypto algorithms was added to both the PMDs.
135 * Added support for lookaside protocol (IPsec) offload in cn10k PMD.
136 * Added support for asymmetric crypto operations in cn9k and cn10k PMD.
138 * **Updated Marvell OCTEON TX crypto PMD.**
140 Added support for crypto adapter ``OP_FORWARD`` mode.
142 * **Added support for Nvidia crypto device driver.**
144 Added mlx5 crypto driver to support AES-XTS cipher operations.
145 The first device to support it is ConnectX-6.
147 * **Updated ISAL compress device PMD.**
149 The ISAL compress device PMD now supports Arm platforms.
151 * **Added Baseband PHY CNXK PMD.**
153 Added Baseband PHY PMD which allows configuration of the BPHY hardware block
154 comprising accelerators and DSPs specifically tailored for 5G/LTE inline
155 use cases. Configuration happens via standard rawdev enq/deq operations. See
156 the :doc:`../rawdevs/cnxk_bphy` rawdev guide for more details on this driver.
158 * **Added support for Marvell CN10K, CN9K, event Rx/Tx adapter.**
160 * Added Rx/Tx adapter support for event/cnxk when the Ethernet device requested
162 * Added support for event vectorization for Rx/Tx adapter.
164 * **Added cppc_cpufreq support to Power Management library.**
166 Added support for cppc_cpufreq driver which works on most arm64 platforms.
168 * **Added multi-queue support to Ethernet PMD Power Management.**
170 The experimental PMD power management API now supports managing
171 multiple Ethernet Rx queues per lcore.
173 * **Updated testpmd to output log errors to stderr.**
175 Updated testpmd application to output log errors and warnings to stderr
182 .. This section should contain API changes. Sample format:
184 * sample: Add a short 1-2 sentence description of the API change
185 which was announced in the previous releases and made in this release.
186 Start with a scope label like "ethdev:".
187 Use fixed width quotes for ``function_names`` or ``struct_names``.
190 This section is a comment. Do not overwrite or remove it.
191 Also, make sure to start the actual text at the margin.
192 =======================================================
194 * eal: ``rte_strscpy`` sets ``rte_errno`` to ``E2BIG`` in case of string
197 * eal: ``rte_bsf32_safe`` now takes a 32-bit value for its first argument.
198 This fixes warnings about loss of precision
199 when used with some compilers settings.
201 * eal: ``rte_power_monitor`` and the ``rte_power_monitor_cond`` struct changed
202 to use a callback mechanism.
204 * rte_power: The experimental PMD power management API is no longer considered
205 to be thread safe; all Rx queues affected by the API will now need to be
206 stopped before making any changes to the power management scheme.
212 .. This section should contain ABI changes. Sample format:
214 * sample: Add a short 1-2 sentence description of the ABI change
215 which was announced in the previous releases and made in this release.
216 Start with a scope label like "ethdev:".
217 Use fixed width quotes for ``function_names`` or ``struct_names``.
220 This section is a comment. Do not overwrite or remove it.
221 Also, make sure to start the actual text at the margin.
222 =======================================================
224 * No ABI change that would break compatibility with 20.11.
230 .. This section should contain new known issues in this release. Sample format:
232 * **Add title in present tense with full stop.**
234 Add a short 1-2 sentence description of the known issue
235 in the present tense. Add information on any known workarounds.
237 This section is a comment. Do not overwrite or remove it.
238 Also, make sure to start the actual text at the margin.
239 =======================================================
241 * **Last mbuf segment not implicitly reset.**
243 It is expected that free mbufs have their field ``nb_seg`` set to 1,
244 so that when it is allocated, the user does not need to set its value.
245 The mbuf free functions are responsible of resetting this field to 1
246 before returning the mbuf to the pool.
248 When a multi-segment mbuf is freed, the field ``nb_seg`` is not reset
249 to 1 for the last segment of the chain. On next allocation of this segment,
250 if the field is not explicitly reset by the user,
251 an invalid mbuf can be created, and can cause an undefined behavior.
253 This issue has a root cause in DPDK 17.05, meaning it is 4 years old.
254 A fix is available and discussed but not merged in DPDK 21.08:
255 https://patches.dpdk.org/patch/86458/
261 .. This section should contain a list of platforms that were tested
266 * <vendor> platform with <vendor> <type of devices> combinations
271 * Other relevant details...
