This section should contain new features added in this release. 29 Sample format: 30 31 * **Add a title in the past tense with a full stop.** 32 33 Add a short 1-2 sentence description in the past tense. 34 The description should be enough to allow someone scanning 35 the release notes to understand the new feature. 36 37 If the feature adds a lot of sub-features you can use a bullet list 38 like this: 39 40 * Added feature foo to do something. 41 * Enhanced feature bar to do something else. 42 43 Refer to the previous release notes for examples. 44 45 Suggested order in release notes items: 46 * Core libs (EAL, mempool, ring, mbuf, buses) 47 * Device abstraction libs and PMDs 48 - ethdev (lib, PMDs) 49 - cryptodev (lib, PMDs) 50 - eventdev (lib, PMDs) 51 - etc 52 * Other libs 53 * Apps, Examples, Tools (if significant) 54 55 This section is a comment. Do not overwrite or remove it. 56 Also, make sure to start the actual text at the margin. 57 ========================================================= 58 59* **Added non-EAL threads registration API.** 60 61 Added a new API to register non-EAL threads as lcores. This can be used by 62 applications to have its threads known of DPDK without suffering from the 63 non-EAL previous limitations in terms of performance. 64 65* **rte_*mb APIs are updated to use DMB instruction for ARMv8.** 66 67 ARMv8 memory model has been strengthened to require other-multi-copy 68 atomicity. This allows for using DMB instruction instead of DSB for IO 69 barriers. rte_*mb APIs, for ARMv8 platforms, are changed to use DMB 70 instruction to reflect this. 71 72* **Added the support for vfio-pci new VF token interface.** 73 74 From Linux 5.7, vfio-pci supports to bind both SR-IOV PF and the created VFs, 75 it uses a shared VF token (UUID) to represent the collaboration between PF 76 and VFs. Update DPDK PCI driver to gain the access to the PF and VFs devices 77 by appending the VF token parameter. 78 79* **Added the RegEx Library, a generic RegEx service library.** 80 81 Added the RegEx library which provides an API for offload of regular 82 expressions search operations to hardware or software accelerator devices. 83 84* **Updated PCAP driver.** 85 86 Updated PCAP driver with new features and improvements, including: 87 88 * Support software Tx nanosecond timestamps precision. 89 90* **Updated Mellanox mlx5 driver.** 91 92 Updated Mellanox mlx5 driver with new features and improvements, including: 93 94 * Added new PMD devarg ``reclaim_mem_mode``. 95 * Added new devarg ``lacp_by_user``. 96 97* **Added vDPA device APIs to query virtio queue statistics.** 98 99 A new 3 APIs has been added to query virtio queue statistics, to get their 100 names and to reset them by a vDPA device. 101 102* **Updated Mellanox mlx5 vDPA driver.** 103 104 Updated Mellanox mlx5 vDPA driver with new features, including: 105 106 * Added support for virtio queue statistics. 107 * Added support for MTU update. 108 109* **Updated Marvell octeontx2 ethdev PMD.** 110 111 Updated Marvell octeontx2 driver with cn98xx support. 112 113* **Updated the Intel ice driver.** 114 115 Updated the Intel ice driver with new features and improvements, including: 116 117 * Added support for DCF datapath configuration. 118 119* **Added DOCSIS protocol to rte_security.** 120 121 Added support for combined crypto and CRC operations for the DOCSIS protocol 122 to ``rte_security`` API. 123 124* **Updated the AESNI MB crypto PMD.** 125 126 Added support for lookaside protocol offload for DOCSIS through the 127 ``rte_security`` API. 128 129* **Updated the QuickAssist Technology (QAT) PMD.** 130 131 * Added support for lookaside protocol offload for DOCSIS through the 132 ``rte_security`` API. 133 134* **Updated the OCTEON TX2 crypto PMD.** 135 136 Added Chacha20-Poly1305 AEAD algorithm support in OCTEON TX2 crypto PMD. 137 138* **Added support for BPF_ABS/BPF_IND load instructions.** 139 140 Added support for two BPF non-generic instructions: 141 ``(BPF_ABS | <size> | BPF_LD)`` and ``(BPF_IND | <size> | BPF_LD)`` 142 which are used to access packet data in a safe manner. Currently JIT support 143 for these instructions is implemented for x86 only. 144 145* **Added flow performance test application.** 146 147 Added new application to test ``rte_flow`` performance, including: 148 149 * Measure ``rte_flow`` insertion rate. 150 * Measure ``rte_flow`` deletion rate. 151 * Dump ``rte_flow`` memory consumption. 152 * Measure packet per second forwarding. 153 154* **Added --portmap command line parameter to l2fwd example.** 155 156 Added new command line option ``--portmap="(port, port)[,(port, port)]"`` to 157 pass forwarding port details. 158 See the :doc:`../sample_app_ug/l2_forward_real_virtual` for more 159 details of this parameter usage. 160 161 162Removed Items 163------------- 164 165..
