1DPDK Release 16.04 2================== 3 4 5New Features 6------------ 7 8* **Added function to check primary process state.** 9 10 A new function ``rte_eal_primary_proc_alive()`` has been added 11 to allow the user to detect if a primary process is running. 12 Use cases for this feature include fault detection, and monitoring 13 using secondary processes. 14 15* **Enabled bulk allocation of mbufs.** 16 17 A new function ``rte_pktmbuf_alloc_bulk()`` has been added to allow the user 18 to bulk allocate mbufs. 19 20* **Added device link speed capabilities.** 21 22 The structure ``rte_eth_dev_info`` now has a ``speed_capa`` bitmap, which 23 allows the application to determine the supported speeds of each device. 24 25* **Added bitmap of link speeds to advertise.** 26 27 Added a feature to allow the definition of a set of advertised speeds for auto-negotiation, 28 explicitly disabling link auto-negotiation (single speed) 29 and full auto-negotiation. 30 31* **Added new poll-mode driver for Amazon Elastic Network Adapters (ENA).** 32 33 The driver operates for a variety of ENA adapters through feature negotiation 34 with the adapter and upgradable commands set. 35 The ENA driver handles PCI Physical and Virtual ENA functions. 36 37* **Restored vmxnet3 TX data ring.** 38 39 TX data ring has been shown to improve small packet forwarding performance 40 on the vSphere environment. 41 42* **Added vmxnet3 TX L4 checksum offload.** 43 44 Added support for TCP/UDP checksum offload to vmxnet3. 45 46* **Added vmxnet3 TSO support.** 47 48 Added support for TSO to vmxnet3. 49 50* **Added vmxnet3 support for jumbo frames.** 51 52 Added support for linking multi-segment buffers together to 53 handle Jumbo packets. 54 55* **Enabled Virtio 1.0 support.** 56 57 Enabled Virtio 1.0 support for Virtio pmd driver. 58 59* **Supported Virtio for ARM.** 60 61 Enabled Virtio support for ARMv7/v8. Tested for ARM64. 62 Virtio for ARM supports VFIO-noiommu mode only. 63 Virtio can work with other non-x86 architectures as well, like PowerPC. 64 65* **Supported Virtio offload in vhost-user.** 66 67 Added the offload and negotiation of checksum and TSO between vhost-user and 68 vanilla Linux Virtio guest. 69 70* **Added vhost-user live migration support.** 71 72* **Added vhost driver.** 73 74 Added a virtual PMD that wraps ``librte_vhost``. 75 76* **Added multicast promiscuous mode support on VF for ixgbe.** 77 78 Added multicast promiscuous mode support for the ixgbe VF driver so all VFs 79 can receive the multicast packets. 80 81 Please note if you want to use this promiscuous mode, you need both PF and VF 82 driver to support it. The reason is that this VF feature is configured in the PF. 83 If you use kernel PF driver and the dpdk VF driver, make sure the kernel PF driver supports 84 VF multicast promiscuous mode. If you use dpdk PF and dpdk VF ensure the PF 85 driver is the same version as the VF. 86 87* **Added support for E-tag on X550.** 88 89 E-tag is defined in `802.1BR - Bridge Port Extension <http://www.ieee802.org/1/pages/802.1br.html>`_. 90 91 This feature is for the VF, but the settings are on the PF. It means 92 the CLIs should be used on the PF, but some of their effects will be shown on the VF. 93 The forwarding of E-tag packets based on GRP and E-CID_base will have an effect 94 on the PF. Theoretically, the E-tag packets can be forwarded to any pool/queue 95 but normally we'd like to forward the packets to the pools/queues belonging 96 to the VFs. And E-tag insertion and stripping will have an effect on VFs. When 97 a VF receives E-tag packets it should strip the E-tag. When the VF transmits 98 packets, it should insert the E-tag. Both actions can be offloaded. 99 100 When we want to use this E-tag support feature, the forwarding should be 101 enabled to forward the packets received by the PF to the indicated VFs. And insertion 102 and stripping should be enabled for VFs to offload the effort to hardware. 103 104 Features added: 105 106 * Support E-tag offloading of insertion and stripping. 107 * Support Forwarding E-tag packets to pools based on 108 GRP and E-CID_base. 109 110* **Added support for VxLAN and NVGRE checksum off-load on X550.** 111 112 * Added support for VxLAN and NVGRE RX/TX checksum off-load on 113 X550. RX/TX checksum off-load is provided on both inner and 114 outer IP header and TCP header. 115 * Added functions to support VxLAN port configuration. The 116 default VxLAN port number is 4789 but this can be updated 117 programmatically. 118 119* **Added support for new X550EM_a devices.** 120 121 Added support for new X550EM_a devices and their MAC types, X550EM_a and X550EM_a_vf. 122 Updated the relevant PMD to use the new devices and MAC types. 123 124* **Added x550em_x V2 device support.** 125 126 Added support for x550em_x V2 device. Only x550em_x V1 was supported before. 127 A mask for V1 and V2 is defined and used to support both. 128 129* **Supported link speed auto-negotiation on X550EM_X** 130 131 Normally the auto-negotiation is supported by firmware and software doesn't care about 132 it. But on x550em_x, firmware doesn't support auto-negotiation. As the ports of x550em_x 133 are 10GbE, if we connect the port with a peer which is 1GbE, the link will always 134 be down. 135 We added the support for auto-negotiation by software to avoid this link down issue. 136 137* **Added software-firmware sync on X550EM_a.** 138 139 Added support for software-firmware sync for resource sharing. 140 Use the PHY token, shared between software-firmware for PHY access on X550EM_a. 141 142* **Updated the i40e base driver.** 143 144 The i40e base driver was updated with changes including the 145 following: 146 147 * Use RX control AQ commands to read/write RX control registers. 148 * Add new X722 device IDs, and removed X710 one was never used. 149 * Expose registers for HASH/FD input set configuring. 150 151* **Enabled PCI extended tag for i40e.** 152 153 Enabled extended tag for i40e by checking and writing corresponding PCI config 154 space bytes, to boost the performance. 155 The legacy method of reading/writing sysfile supported by kernel module igb_uio 156 is now deprecated. 157 158* **Added i40e support for setting mac addresses.** 159 160* **Added dump of i40e registers and EEPROM.** 161 162* **Supported ether type setting of single and double VLAN for i40e** 163 164* **Added VMDQ DCB mode in i40e.** 165 166 Added support for DCB in VMDQ mode to i40e driver. 167 168* **Added i40e VEB switching support.** 169 170* **Added Flow director enhancements in i40e.** 171 172* **Added PF reset event reporting in i40e VF driver.** 173 174* **Added fm10k RX interrupt support.** 175 176* **Optimized fm10k TX.** 177 178 Optimized fm10k TX by freeing multiple mbufs at a time. 179 180* **Handled error flags in fm10k vector RX.** 181 182 Parse error flags in RX descriptor and set error bits in mbuf with vector instructions. 183 184* **Added fm10k FTAG based forwarding support.** 185 186* **Added mlx5 flow director support.** 187 188 Added flow director support (``RTE_FDIR_MODE_PERFECT`` and 189 ``RTE_FDIR_MODE_PERFECT_MAC_VLAN``). 190 191 Only available with Mellanox OFED >= 3.2. 192 193* **Added mlx5 RX VLAN stripping support.** 194 195 Added support for RX VLAN stripping. 196 197 Only available with Mellanox OFED >= 3.2. 198 199* **Added mlx5 link up/down callbacks.** 200 201 Implemented callbacks to bring link up and down. 202 203* **Added mlx5 support for operation in secondary processes.** 204 205 Implemented TX support in secondary processes (like mlx4). 206 207* **Added mlx5 RX CRC stripping configuration.** 208 209 Until now, CRC was always stripped. It can now be configured. 210 211 Only available with Mellanox OFED >= 3.2. 212 213* **Added mlx5 optional packet padding by HW.** 214 215 Added an option to make PCI bus transactions rounded to a multiple of a 216 cache line size for better alignment. 217 218 Only available with Mellanox OFED >= 3.2. 219 220* **Added mlx5 TX VLAN insertion support.** 221 222 Added support for TX VLAN insertion. 223 224 Only available with Mellanox OFED >= 3.2. 225 226* **Changed szedata2 driver type from vdev to pdev.** 227 228 Previously szedata2 device had to be added by ``--vdev`` option. 229 Now szedata2 PMD recognizes the device automatically during EAL 230 initialization. 231 232* **Added szedata2 functions for setting link up/down.** 233 234* **Added szedata2 promiscuous and allmulticast modes.** 235 236* **Added af_packet dynamic removal function.** 237 238 An af_packet device can now be detached using the API, like other PMD devices. 239 240* **Increased number of next hops for LPM IPv4 to 2^24.** 241 242 The ``next_hop`` field has been extended from 8 bits to 24 bits for IPv4. 243 244* **Added support of SNOW 3G (UEA2 and UIA2) for Intel Quick Assist devices.** 245 246 Enabled support for the SNOW 3G wireless algorithm for Intel Quick Assist devices. 247 Support for cipher-only and hash-only is also provided 248 along with algorithm-chaining operations. 249 250* **Added SNOW3G SW PMD.** 251 252 A new Crypto PMD has been added, which provides SNOW 3G UEA2 ciphering 253 and SNOW3G UIA2 hashing. 254 255* **Added AES GCM PMD.** 256 257 Added new Crypto PMD to support AES-GCM authenticated encryption and 258 authenticated decryption in software. 259 260* **Added NULL Crypto PMD** 261 262 Added new Crypto PMD to support null crypto operations in software. 263 264* **Improved IP Pipeline Application.** 265 266 The following features have been added to ip_pipeline application; 267 268 * Added CPU utilization measurement and idle cycle rate computation. 269 * Added link identification support through existing port-mask option or by 270 specifying PCI device in every LINK section in the configuration file. 271 * Added load balancing support in passthrough pipeline. 272 273* **Added IPsec security gateway example.** 274 275 Added a new application implementing an IPsec Security Gateway. 276 277 278Resolved Issues 279--------------- 280 281Drivers 282~~~~~~~ 283 284* **ethdev: Fixed overflow for 100Gbps.** 285 286 100Gbps in Mbps (100000) was exceeding the 16-bit max value of ``link_speed`` 287 in ``rte_eth_link``. 288 289* **ethdev: Fixed byte order consistency between fdir flow and mask.** 290 291 Fixed issue in ethdev library where the structure for setting 292 fdir's mask and flow entry was not consistent in byte ordering. 293 294* **cxgbe: Fixed crash due to incorrect size allocated for RSS table.** 295 296 Fixed a segfault that occurs when accessing part of port 0's RSS 297 table that gets overwritten by subsequent port 1's part of the RSS 298 table due to incorrect size allocated for each entry in the table. 299 300* **cxgbe: Fixed setting wrong device MTU.** 301 302 Fixed an incorrect device MTU being set due to the Ethernet header and 303 CRC lengths being added twice. 304 305* **ixgbe: Fixed zeroed VF mac address.** 306 307 Resolved an issue where the VF MAC address is zeroed out in cases where the VF 308 driver is loaded while the PF interface is down. 309 The solution is to only set it when we get an ACK from the PF. 310 311* **ixgbe: Fixed setting flow director flag twice.** 312 313 Resolved an issue where packets were being dropped when switching to perfect 314 filters mode. 315 316* **ixgbe: Set MDIO speed after MAC reset.** 317 318 The MDIO clock speed must be reconfigured after the MAC reset. The MDIO clock 319 speed becomes invalid, therefore the driver reads invalid PHY register values. 320 The driver now set the MDIO clock speed prior to initializing PHY ops and 321 again after the MAC reset. 322 323* **ixgbe: Fixed maximum number of available TX queues.** 324 325 In IXGBE, the maximum number of TX queues varies depending on the NIC operating 326 mode. This was not being updated in the device information, providing 327 an incorrect number in some cases. 328 329* **i40e: Generated MAC address for each VFs.** 330 331 It generates a MAC address for each VFs during PF host initialization, 332 and keeps the VF MAC address the same among different VF launch. 333 334* **i40e: Fixed failure of reading/writing RX control registers.** 335 336 Fixed i40e issue of failing to read/write rx control registers when 337 under stress with traffic, which might result in application launch 338 failure. 339 340* **i40e: Enabled vector driver by default.** 341 342 Previously, vector driver was disabled by default as it couldn't fill packet type 343 info for l3fwd to work well. Now there is an option for l3fwd to analyze 344 the packet type so the vector driver is enabled by default. 345 346* **i40e: Fixed link info of VF.** 347 348 Previously, the VF's link speed stayed at 10GbE and status always was up. 349 It did not change even when the physical link's status changed. 350 Now this issue is fixed to make VF's link info consistent with physical link. 351 352* **mlx5: Fixed possible crash during initialization.** 353 354 A crash could occur when failing to allocate private device context. 355 356* **mlx5: Added port type check.** 357 358 Added port type check to prevent port initialization on non-Ethernet link layers and 359 to report an error. 360 361* **mlx5: Applied VLAN filtering to broadcast and IPv6 multicast flows.** 362 363 Prevented reception of multicast frames outside of configured VLANs. 364 365* **mlx5: Fixed RX checksum offload in non L3/L4 packets.** 366 367 Fixed report of bad checksum for packets of unknown type. 368 369* **aesni_mb: Fixed wrong return value when creating a device.** 370 371 The ``cryptodev_aesni_mb_init()`` function was returning the device id of the device created, 372 instead of 0 (on success) that ``rte_eal_vdev_init()`` expects. 373 This made it impossible to create more than one aesni_mb device 374 from the command line. 375 376* **qat: Fixed AES GCM decryption.** 377 378 Allowed AES GCM on the cryptodev API, but in some cases gave invalid results 379 due to incorrect IV setting. 380 381 382Libraries 383~~~~~~~~~ 384 385* **hash: Fixed CRC32c hash computation for non multiple of 4 bytes sizes.** 386 387 Fix crc32c hash functions to return a valid crc32c value for data lengths 388 not a multiple of 4 bytes. 389 390* **hash: Fixed hash library to support multi-process mode.** 391 392 Fix hash library to support multi-process mode, using a jump table, 393 instead of storing a function pointer to the key compare function. 394 Multi-process mode only works with the built-in compare functions, 395 however a custom compare function (not in the jump table) can only 396 be used in single-process mode. 397 398* **hash: Fixed return value when allocating an existing hash table.** 399 400 Changed the ``rte_hash*_create()`` functions to return ``NULL`` and set 401 ``rte_errno`` to ``EEXIST`` when the object name already exists. This is 402 the behavior described in the API documentation in the header file. 403 The previous behavior was to return a pointer to the existing object in 404 that case, preventing the caller from knowing if the object had to be freed 405 or not. 406 407* **lpm: Fixed return value when allocating an existing object.** 408 409 Changed the ``rte_lpm*_create()`` functions to return ``NULL`` and set 410 ``rte_errno`` to ``EEXIST`` when the object name already exists. This is 411 the behavior described in the API documentation in the header file. 412 The previous behavior was to return a pointer to the existing object in 413 that case, preventing the caller from knowing if the object had to be freed 414 or not. 415 416* **librte_port: Fixed segmentation fault for ring and ethdev writer nodrop.** 417 418 Fixed core dump issue on txq and swq when dropless is set to yes. 419 420 421Examples 422~~~~~~~~ 423 424* **l3fwd-power: Fixed memory leak for non-IP packet.** 425 426 Fixed issue in l3fwd-power where, on receiving packets of types 427 other than IPv4 or IPv6, the mbuf was not released, and caused 428 a memory leak. 429 430* **l3fwd: Fixed using packet type blindly.** 431 432 l3fwd makes use of packet type information without querying if devices or PMDs 433 really set it. For those devices that don't set ptypes, add an option to parse it. 434 435* **examples/vhost: Fixed frequent mbuf allocation failure.** 436 437 The vhost-switch often fails to allocate mbuf when dequeue from vring because it 438 wrongly calculates the number of mbufs needed. 439 440 441API Changes 442----------- 443 444* The ethdev statistics counter ``imissed`` is considered to be independent of ``ierrors``. 445 All drivers are now counting the missed packets only once, i.e. drivers will 446 not increment ierrors anymore for missed packets. 447 448* The ethdev structure ``rte_eth_dev_info`` was changed to support device 449 speed capabilities. 450 451* The ethdev structures ``rte_eth_link`` and ``rte_eth_conf`` were changed to 452 support the new link API. 453 454* The functions ``rte_eth_dev_udp_tunnel_add`` and ``rte_eth_dev_udp_tunnel_delete`` 455 have been renamed into ``rte_eth_dev_udp_tunnel_port_add`` and 456 ``rte_eth_dev_udp_tunnel_port_delete``. 457 458* The ``outer_mac`` and ``inner_mac`` fields in structure 459 ``rte_eth_tunnel_filter_conf`` are changed from pointer to struct in order 460 to keep code's readability. 461 462* The fields in ethdev structure ``rte_eth_fdir_masks`` were changed 463 to be in big endian. 464 465* A parameter ``vlan_type`` has been added to the function 466 ``rte_eth_dev_set_vlan_ether_type``. 467 468* The af_packet device init function is no longer public. The device should be attached 469 via the API. 470 471* The LPM ``next_hop`` field is extended from 8 bits to 24 bits for IPv4 472 while keeping ABI compatibility. 473 474* A new ``rte_lpm_config`` structure is used so the LPM library will allocate 475 exactly the amount of memory which is necessary to hold application’s rules. 476 The previous ABI is kept for compatibility. 477 478* The prototype for the pipeline input port, output port and table action 479 handlers are updated: the pipeline parameter is added, 480 the packets mask parameter has been either removed or made input-only. 481 482 483ABI Changes 484----------- 485 486* The RETA entry size in ``rte_eth_rss_reta_entry64`` has been increased 487 from 8-bit to 16-bit. 488 489* The ethdev flow director structure ``rte_eth_fdir_flow`` structure was 490 changed. New fields were added to extend flow director's input set. 491 492* The cmdline buffer size has been increase from 256 to 512. 493 494 495Shared Library Versions 496----------------------- 497 498The libraries prepended with a plus sign were incremented in this version. 499 500.. code-block:: diff 501 502 + libethdev.so.3 503 librte_acl.so.2 504 librte_cfgfile.so.2 505 + librte_cmdline.so.2 506 librte_distributor.so.1 507 librte_eal.so.2 508 librte_hash.so.2 509 librte_ip_frag.so.1 510 librte_ivshmem.so.1 511 librte_jobstats.so.1 512 librte_kni.so.2 513 librte_kvargs.so.1 514 librte_lpm.so.2 515 librte_mbuf.so.2 516 librte_mempool.so.1 517 librte_meter.so.1 518 + librte_pipeline.so.3 519 librte_pmd_bond.so.1 520 librte_pmd_ring.so.2 521 librte_port.so.2 522 librte_power.so.1 523 librte_reorder.so.1 524 librte_ring.so.1 525 librte_sched.so.1 526 librte_table.so.2 527 librte_timer.so.1 528 librte_vhost.so.2 529 530 531Tested Platforms 532---------------- 533 534#.
