1. DPDK Release 21.02

Note

A dependency has been added for building DPDK on Linux or FreeBSD: the Python module pyelftools (version 0.22 or greater), often packaged as python3-pyelftools, is required.

If not available as a distribution package, it can be installed with:

pip3 install pyelftools

1.1. New Features

  • Added new ethdev API for PMD power management.

    Added rte_eth_get_monitor_addr(), to be used in conjunction with rte_power_monitor() to enable automatic power management for PMDs.

  • Added Ethernet PMD power management helper API.

    A new helper API has been added to make using Ethernet PMD power management easier for the user: rte_power_ethdev_pmgmt_queue_enable(). Three power management schemes are supported initially:

    • Power saving based on UMWAIT instruction (x86 only)

    • Power saving based on rte_pause() (generic) or TPAUSE instruction (x86 only)

    • Power saving based on frequency scaling through the librte_power library

  • Added GENEVE TLV option in rte_flow.

    Added support for matching and raw encap/decap of GENEVE TLV option.

  • Added support for Modify field action in the flow API.

    Added “modify” action support to rte_flow to perform various operations on any arbitrary header field (as well as mark, metadata or tag values): RTE_FLOW_ACTION_TYPE_MODIFY_FIELD. Supported operations are: overwriting a field with the content from another field, addition and subtraction using an immediate value.

    • Added Double VLAN support for DCF switch QinQ filtering.

    • Added support for UDP dynamic port assignment for eCPRI tunnels in DCF.

  • Updated Intel iavf driver.

    Updated iavf PMD with new features and improvements, including:

    • Added support for FDIR/RSS packet steering for eCPRI flow.

    • Added support for FDIR TCP/UDP pattern without input set.

  • Updated Mellanox mlx5 driver.

    Updated the Mellanox mlx5 driver with new features and improvements, including:

    • Introduced basic support on Windows.

    • Added GTP PDU session container matching and raw encap/decap.

    • Added support for a RSS action in the sample sub-actions list.

    • Added support for E-Switch mirroring and jump action in the same flow.

    • Added support to handle the modify action in correct order regarding the mirroring action on E-Switch.

    • Enlarged the number of flow priorities to 21844 (0 - 21843) for ingress or egress flow groups greater than 0 and for any transfer flow group.

    • Added support for the Tx mbuf fast free offload.

    • Added support for flow modify field action.

  • Updated the Pensando ionic driver.

    Updated the Pensando ionic driver with new features and improvements, including:

    • Fixed bugs related to link autonegotiation.

    • Fixed bugs related to port start/stop and queue start/stop.

    • Added support for probing the supported queue versions. Note that extremely old (pre-1.0) firmware will no longer be usable with the PMD.

    • Removed unused code.

    • Reduced device startup time.

  • Updated Wangxun txgbe driver.

    Updated the Wangxun txgbe driver with new features and improvements, including:

    • Add support for generic flow API.

    • Add support for traffic manager.

    • Add support for IPsec.

  • Updated GSO support.

    • Added inner UDP/IPv4 support for VXLAN IPv4 GSO.

  • Added enqueue and dequeue callback APIs for cryptodev library.

    The Cryptodev library has been enhanced with enqueue and dequeue callback APIs to enable applications to add/remove user callbacks which get called for every enqueue/dequeue operation.

  • Updated the OCTEON TX2 crypto PMD.

    • Updated the OCTEON TX2 crypto PMD lookaside protocol offload for IPsec with ESN and anti-replay support.

    • Updated the OCTEON TX2 crypto PMD with CN98xx support.

    • Added support for aes-cbc sha1-hmac cipher combination in OCTEON TX2 crypto PMD lookaside protocol offload for IPsec.

    • Added support for aes-cbc sha256-128-hmac cipher combination in OCTEON TX2 crypto PMD lookaside protocol offload for IPsec.

  • Added mlx5 compress PMD.

    Added a new compress PMD driver for Bluefield 2 adapters.

    See the MLX5 compress driver for more details.

  • Added python script to run crypto perf tests and graph the results.

    A new Python script has been added to automate running crypto performance tests and output graphed results to PDF files. See the dpdk-test-crypto-perf Application guide for more details.

  • Added Windows support to pmdinfogen.

    PMD information strings were added for Windows as well as for other OS. Extracting them from Windows DLL is not yet supported. The build-time tool pmdinfogen was rewritten in Python, thus libelf dependency was replaced with pyelftools as new build dependency.

  • Added support for build-time checking of header includes.

    A new build option check_includes has been added, which, when enabled, will perform build-time checking on DPDK public header files, to ensure none are missing dependent header includes. This feature, disabled by default, is intended for use by developers contributing to the DPDK SDK itself, and is integrated into the build scripts and automated CI for patch contributions.

1.2. Removed Items

  • The internal header files rte_ethdev_driver.h, rte_ethdev_vdev.h and rte_ethdev_pci.h are no longer installed as part of the DPDK ninja install action and are renamed to ethdev_driver.h, ethdev_vdev.h and ethdev_pci.h respectively in the source tree, to reflect the fact that they are non-public headers.

  • The internal header files rte_eventdev_pmd.h, rte_eventdev_pmd_vdev.h and rte_eventdev_pmd_pci.h are no longer installed as part of the DPDK ninja install action and are renamed to eventdev_pmd.h, eventdev_pmd_vdev.h and eventdev_pmd_pci.h respectively in the source tree, to reflect the fact that they are non-public headers.

  • Removed support for NetXtreme devices belonging to BCM573xx and BCM5740x families. Specifically the support for the following Broadcom PCI device IDs 0x16c8, 0x16c9, 0x16ca, 0x16ce, 0x16cf, 0x16df, 0x16d0, 0x16d1, 0x16d2, 0x16d4, 0x16d5, 0x16e7, 0x16e8, 0x16e9 has been removed.

  • The check-includes.sh script for checking DPDK header files has been removed, being replaced by the check_includes build option described above.

1.3. API Changes

  • config: Removed the old macros, included in rte_config.h, to indicate which DPDK libraries and drivers are built. The new macros are generated by meson in a standardized format: RTE_LIB_<NAME> and RTE_<CLASS>_<NAME>, where NAME is the upper-case component name, e.g. EAL, ETHDEV, VIRTIO, and CLASS is the upper-case driver class, e.g. NET, CRYPTO.

  • cryptodev: The structure rte_cryptodev has been updated with pointers for adding enqueue and dequeue callbacks.

1.4. ABI Changes

  • No ABI change that would break compatibility with 20.11.

  • The experimental function rte_telemetry_init has been removed from the public API and is now an internal-only function. Where telemetry library is available, it is called automatically from rte_eal_init() and so no end application need use it.
