6. DPDK Release 18.11

6.1. New Features

• Added support for using externally allocated memory in DPDK.

  DPDK has added support for creating new rte_malloc heaps referencing memory that was created outside of DPDK’s own page allocator, and using that memory natively with any other DPDK library or data structure.

• Added check for ensuring allocated memory is addressable by devices.

  Some devices can have addressing limitations so a new function, rte_mem_check_dma_mask(), has been added for checking that allocated memory is not out of the device range. Since memory can now be allocated dynamically after initialization, a DMA mask is stored and any new allocated memory will be checked against it and rejected if it is out of range. If more than one device has addressing limitations, the DMA mask is the more restrictive one.

• Updated the C11 memory model version of the ring library.

  Added changes to decrease latency for architectures using the C11 memory model version of the ring library.

  On Cavium ThunderX2 platform, the changes decreased latency by 27-29% and 3-15% for MPMC and SPSC cases respectively (with 2 lcores). The real improvements may vary with the number of contending lcores and the size of the ring.

• Added hot-unplug handle mechanism.

  Added rte_dev_hotplug_handle_enable() and rte_dev_hotplug_handle_disable() for enabling or disabling the hotplug handle mechanism.

• Added support for device multi-process hotplug.

  Added support for hotplug and hot-unplug in a multiprocessing scenario. Any ethdev devices created in the primary process will be regarded as shared and will be available for all DPDK processes. Synchronization between processes will be done using DPDK IPC.

• Added new Flow API actions to rewrite fields in packet headers.

  Added new Flow API actions to:

  • Modify source and destination IP addresses in the outermost IPv4/IPv6 headers.
  • Modify source and destination port numbers in the outermost TCP/UDP headers.

• Added new Flow API action to swap MAC addresses in Ethernet header.

  Added new Flow API action to swap the source and destination MAC addresses in the outermost Ethernet header.

• Add support to offload more flow match and actions for CXGBE PMD.

  The Flow API support has been enhanced for the CXGBE Poll Mode Driver to offload:

  • Match items: destination MAC address.
  • Action items: push/pop/rewrite vlan header, rewrite IP addresses in outermost IPv4/IPv6 header, rewrite port numbers in outermost TCP/UDP header, swap MAC addresses in outermost Ethernet header.

• Added a devarg to use the latest supported vector path in i40e.

  A new devarg use-latest-supported-vec was introduced to allow users to choose the latest vector path that the platform supported. For example, users can use AVX2 vector path on BDW/HSW to get better performance.

• Added support for SR-IOV in netvsc PMD.

  The netvsc poll mode driver now supports the Accelerated Networking SR-IOV option in Hyper-V and Azure. This is an alternative to the previous vdev_netvsc, tap, and failsafe drivers combination.

• Added a new net driver for Marvell Armada 3k device.

  Added the new mvneta net driver for Marvell Armada 3k device. See the MVNETA Poll Mode Driver NIC guide for more details on this new driver.

• Added NXP ENETC PMD.

  Added the new enetc driver for the NXP enetc platform. See the ENETC Poll Mode Driver NIC driver guide for more details on this new driver.

• Added Ethernet poll mode driver for Aquantia aQtion family of 10G devices.

• Updated mlx5 driver.

  Updated the mlx5 driver including the following changes:

  • Improved security of PMD to prevent the NIC from getting stuck when the application misbehaves.
  • Reworked flow engine to supported e-switch flow rules (transfer attribute).
  • Added support for header re-write(L2-L4), VXLAN encap/decap, count, match on TCP flags and multiple flow groups with e-switch flow rules.
  • Added support for match on metadata, VXLAN and MPLS encap/decap with flow rules.
  • Added support for RTE_ETH_DEV_CLOSE_REMOVE flag to provide better support for representors.
  • Added support for meson build.
  • Fixed build issue with PPC.

• Updated the enic driver.

  • Added AVX2-based vectorized Rx handler.
  • Added VLAN and checksum offloads to the simple Tx handler.
  • Added the “count” flow action.
  • Enabled the virtual address IOVA mode.

• Updated the failsafe driver.

  Updated the failsafe driver including the following changes:

  • Added support for Rx and Tx queues deferred start.
  • Added support for runtime Rx and Tx queues setup.
  • Added support multicast MAC address set.

• Added a devarg to use a PCAP interface physical MAC address.

  A new devarg phy_mac was introduced to allow users to use the physical MAC address of the selected PCAP interface.

• Added TAP Rx/Tx queues sharing with a secondary process.

  Added support to allow a secondary process to attach a TAP device created in the primary process, probe the queues, and process Rx/Tx in a secondary process.

• Added classification and metering support to SoftNIC PMD.

  Added support for flow classification (rte_flow API), and metering and policing (rte_mtr API) to the SoftNIC PMD.

• Added Crypto support to the Softnic PMD.

  The Softnic is now capable of processing symmetric crypto workloads such as cipher, cipher-authentication chaining, and AEAD encryption and decryption. This is achieved by calling DPDK Cryptodev APIs.

• Added cryptodev port to port library.

  Cryptodev port is a shim layer in the port library that interacts with DPDK Cryptodev PMDs including burst enqueuing and dequeuing crypto operations.

• Added symmetric cryptographic actions to the pipeline library.

  In the pipeline library support was added for symmetric crypto action parsing and an action handler was implemented. The action allows automatic preparation of the crypto operation with the rules specified such as algorithm, key, and IV, etc. for the cryptodev port to process.

• Updated the AESNI MB PMD.

  The AESNI MB PMD has been updated with additional support for the AES-GCM algorithm.

• Added NXP CAAM JR PMD.

  Added the new caam job ring driver for NXP platforms. See the NXP CAAM JOB RING (caam_jr) guide for more details on this new driver.

• Added support for GEN3 devices to Intel QAT driver.

  Added support for the third generation of Intel QuickAssist devices.

• Updated the QAT PMD.

  The QAT PMD was updated with additional support for:

  • The AES-CMAC algorithm.

• Added support for Dynamic Huffman Encoding to Intel QAT comp PMD.

  The Intel QuickAssist (QAT) compression PMD has been updated with support for Dynamic Huffman Encoding for the Deflate algorithm.

• Added Event Ethernet Tx Adapter.

  Added event ethernet Tx adapter library that provides configuration and data path APIs for the ethernet transmit stage of an event driven packet processing application. These APIs abstract the implementation of the transmit stage and allow the application to use eventdev PMD support or a common implementation.

• Added Distributed Software Eventdev PMD.

  Added the new Distributed Software Event Device (DSW), which is a pure-software eventdev driver distributing the work of scheduling among all eventdev ports and the lcores using them. DSW, compared to the SW eventdev PMD, sacrifices load balancing performance to gain better event scheduling throughput and scalability.

• Added extendable bucket feature to hash library (rte_hash).

  This new “extendable bucket” feature provides 100% insertion guarantee to the capacity specified by the user by extending hash table with extra buckets when needed to accommodate the unlikely event of intensive hash collisions. In addition, the internal hashing algorithm was changed to use partial-key hashing to improve memory efficiency and lookup performance.

• Added lock free reader/writer concurrency to hash library (rte_hash).

  Lock free reader/writer concurrency prevents the readers from getting blocked due to a preempted writer thread. This allows the hash library to be used in scenarios where the writer thread runs on the control plane.

• Added Traffic Pattern Aware Power Control Library.

  Added an experimental library that extends the Power Library and provides empty_poll APIs. This feature measures how many times empty_polls are executed per core and uses the number of empty polls as a hint for system power management.

  See the Power Management section of the DPDK Programmers Guide document for more information.

• Added JSON power policy interface for containers.

  Extended the Power Library and vm_power_manager sample app to allow power policies to be submitted via a FIFO using JSON formatted strings. Previously limited to Virtual Machines, this feature extends power policy functionality to containers and host applications that need to have their cores frequency controlled based on the rules contained in the policy.

• Added Telemetry API.

  Added a new telemetry API which allows applications to transparently expose their telemetry in JSON via a UNIX socket. The JSON can be consumed by any Service Assurance agent, such as CollectD.

• Updated KNI kernel module, rte_kni library, and KNI sample application.

  Updated the KNI kernel module with a new kernel module parameter, carrier=[on|off] to allow the user to control the default carrier state of the KNI kernel network interfaces. The default carrier state is now set to off, so the interfaces cannot be used until the carrier state is set to on via rte_kni_update_link or by writing 1 to /sys/devices/virtual/net/<iface>/carrier. In previous versions the default carrier state was left undefined. See Kernel NIC Interface for more information.

  Also added the new API function rte_kni_update_link() to allow the user to set the carrier state of the KNI kernel network interface.

  Also added a new command line flag -m to the KNI sample application to monitor and automatically reflect the physical NIC carrier state to the KNI kernel network interface with the new rte_kni_update_link() API. See Kernel NIC Interface Sample Application for more information.

• Added ability to switch queue deferred start flag on testpmd app.

  Added a console command to testpmd app, giving ability to switch rx_deferred_start or tx_deferred_start flag of the specified queue of the specified port. The port must be stopped before the command call in order to reconfigure queues.

• Add a new sample application for vDPA.

  The vdpa sample application creates vhost-user sockets by using the vDPA backend. vDPA stands for vhost Data Path Acceleration which utilizes virtio ring compatible devices to serve virtio driver directly to enable datapath acceleration. As vDPA driver can help to set up vhost datapath, this application doesn’t need to launch dedicated worker threads for vhost enqueue/dequeue operations.

• Added cryptodev FIPS validation example application.

  Added an example application to parse and perform symmetric cryptography computation to the NIST Cryptographic Algorithm Validation Program (CAVP) test vectors.

• Allow unit test binary to take parameters from the environment.

  The unit test “test”, or “dpdk-test”, binary is often called from scripts, which can make passing additional parameters, such as a coremask, difficult. Support has been added to the application to allow it to take additional command-line parameter values from the DPDK_TEST_PARAMS environment variable to make this application easier to use.

6.2. API Changes

• eal: rte_memseg_list structure now has an additional flag indicating whether the memseg list is externally allocated. This will have implications for any users of memseg-walk-related functions, as they will now have to skip externally allocated segments in most cases if the intent is to only iterate over internal DPDK memory.

  In addition the socket_id parameter across the entire DPDK has gained additional meaning, as some socket ID’s will now be representing externally allocated memory. No changes will be required for existing code as backwards compatibility will be kept, and those who do not use this feature will not see these extra socket ID’s. Any new API’s must not check socket ID parameters themselves, and must instead leave it to the memory subsystem to decide whether socket ID is a valid one.

• eal: The following devargs functions, which were deprecated in 18.05, were removed in 18.11: rte_eal_parse_devargs_str(), rte_eal_devargs_add(), rte_eal_devargs_type_count(), and rte_eal_devargs_dump().

• eal: The parameters of the function rte_devargs_remove() have changed from bus and device names to struct rte_devargs.

• eal: The deprecated functions attach/detach were removed in 18.11. rte_eal_dev_attach can be replaced by rte_dev_probe or rte_eal_hotplug_add. rte_eal_dev_detach can be replaced by rte_dev_remove or rte_eal_hotplug_remove.

• eal: The scope of rte_eal_hotplug_add()/rte_dev_probe() and rte_eal_hotplug_remove()/rte_dev_remove() has been extended. In the multi-process model, they will guarantee that the device is attached or detached on all processes.

• mbuf: The __rte_mbuf_raw_free() and __rte_pktmbuf_prefree_seg() functions were deprecated since 17.05 and are replaced by rte_mbuf_raw_free() and rte_pktmbuf_prefree_seg().

• ethdev: The deprecated functions attach/detach were removed in 18.11. rte_eth_dev_attach() can be replaced by RTE_ETH_FOREACH_MATCHING_DEV and rte_dev_probe() or rte_eal_hotplug_add(). rte_eth_dev_detach() can be replaced by rte_dev_remove() or rte_eal_hotplug_remove().

• ethdev: A call to rte_eth_dev_release_port() has been added in rte_eth_dev_close(). As a consequence, a closed port is freed and seen as invalid because of its state RTE_ETH_DEV_UNUSED. This new behavior is enabled per driver for a migration period.

• A new device flag, RTE_ETH_DEV_NOLIVE_MAC_ADDR, changes the order of actions inside rte_eth_dev_start() regarding MAC set. Some NICs do not support MAC changes once the port has started and with this new device flag the MAC can be properly configured in any case. This is particularly important for bonding.

• The default behavior of CRC strip offload has changed in this release. Without any specific Rx offload flag, default behavior by a PMD is now to strip CRC. DEV_RX_OFFLOAD_CRC_STRIP offload flag has been removed. To request keeping CRC, application should set DEV_RX_OFFLOAD_KEEP_CRC Rx offload.

• eventdev: The type of the second parameter to rte_event_eth_rx_adapter_caps_get() has been changed from uint8_t to uint16_t.

• kni: By default, interface carrier status is off which means there won’t be any traffic. It can be set to on via rte_kni_update_link() API or via sysfs interface: echo 1 > /sys/class/net/vEth0/carrier.

  Note interface should be up to be able to read/write sysfs interface. When KNI sample application is used, -m parameter can be used to automatically update the carrier status for the interface.

• kni: When ethtool support is enabled (CONFIG_RTE_KNI_KMOD_ETHTOOL=y) ethtool commands ETHTOOL_GSET & ETHTOOL_SSET are no longer supported for kernels that have ETHTOOL_GLINKSETTINGS & ETHTOOL_SLINKSETTINGS support. This means ethtool "-a|--show-pause", "-s|--change" won’t work, and ethtool <iface> output will have less information.

6.3. ABI Changes

• eal: added legacy_mem and single_file_segments values to rte_config structure on account of improving DPDK usability when using either --legacy-mem or --single-file-segments flags.
• eal: EAL library ABI version was changed due to previously announced work on supporting external memory in DPDK:
  • Structure rte_memseg_list now has a new field indicating length of memory addressed by the segment list
  • Structure rte_memseg_list now has a new flag indicating whether the memseg list refers to external memory
  • Structure rte_malloc_heap now has a new field indicating socket ID the malloc heap belongs to
  • Structure rte_mem_config has had its malloc_heaps array resized from RTE_MAX_NUMA_NODES to RTE_MAX_HEAPS value
  • Structure rte_malloc_heap now has a heap_name member
  • Structure rte_eal_memconfig has been extended to contain next socket ID for externally allocated segments
• eal: Added dma_maskbits to rte_mem_config for keeping the most restrictive DMA mask based on the devices addressing limitations.
• eal: The structure rte_device has a new field to reference a rte_bus. It thus changes the size of the struct rte_device and the inherited device structures of all buses.

6.5. Known Issues

• When using SR-IOV (VF) support with netvsc PMD and the Mellanox mlx5 bifurcated driver the Linux netvsc device must be brought up before the netvsc device is unbound and passed to the DPDK.
• IBM Power8 is not supported in this release of DPDK. IBM Power9 is supported.
• AVX-512 support has been disabled for GCC builds [1] because of a crash [2]. This can affect native machine type build targets on the platforms that support AVX512F like Intel Skylake processors, and can cause a possible performance drop. The immediate workaround is to use clang compiler on these platforms. The issue has been identified as a GCC defect and reported to the GCC community [3]. Further actions will be taken based on the GCC defect result.
