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 addressable by devices.**
+
+ Some devices can have addressing limitations so a new function,
+ ``rte_mem_check_dma_mask``, has been added for checking allocated memory is
+ not out of the device range. Because now memory can be dynamically allocated
+ after initialization, a dma mask is kept and any new allocated memory will be
+ checked out against that dma mask and rejected if out of range. If more than
+ one device has addressing limitations, the dma mask is the more restricted one.
+
+* **Updated the C11 memory model version of ring library.**
+
+ The latency is decreased 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 ring.
+
* **Added hot-unplug handle mechanism.**
``rte_dev_hotplug_handle_enable`` and ``rte_dev_hotplug_handle_disable`` are
See the :doc:`../nics/atlantic` nic driver guide for more details on this
driver.
+* **Updated mlx5 driver.**
+
+ Updated the mlx5 driver including the following changes:
+
+ * Improved security of PMD to prevent the NIC from getting stuck when
+ application misbehaves.
+ * reworked flow engine to supported e-switch flow rules (transfer attribute).
+ * Supported header re-write(L2-L4), VXLAN encap/decap, count ,match
+ on TCP flags and multiple flow groups with e-switch flow rules.
+ * Supported match on medatada, VXLAN and MPLS encap/decap with flow rules.
+ * Supported RTE_ETH_DEV_CLOSE_REMOVE flag to provide better support for
+ representors.
+ * Supported meson build.
+ * Fixed build issue with PPC.
+ * Supported BlueField VF.
+ * Supported externally allocated static memory for DMA.
+
* **Updated Solarflare network PMD.**
Updated the sfc_efx driver including the following changes:
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 the telemetry API which allows applications to transparently expose
+ their telemetry via a UNIX socket in JSON. 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 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 :doc:`../prog_guide/kernel_nic_interface` for more information.
+
+ Added the new API function ``rte_kni_update_link`` to allow the user
+ to set the carrier state of the KNI kernel network interface.
+
+ 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 :doc:`../sample_app_ug/kernel_nic_interface` 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
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, to it more
+ awkward. 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.
+
API Changes
-----------
* eventdev: Type of 2nd 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 enabled (``CONFIG_RTE_KNI_KMOD_ETHTOOL=y``)
+ ethtool commands ``ETHTOOL_GSET & ETHTOOL_SSET`` are no more supported for the
+ kernels that has ``ETHTOOL_GLINKSETTINGS & ETHTOOL_SLINKSETTINGS`` support.
+ This means ``ethtool "-a|--show-pause", "-s|--change"`` won't work, and
+ ``ethtool <iface>`` output will have less information.
+
ABI Changes
-----------
- 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 more restricted
+ dma mask based on devices addressing limitations.
+
* eal: The structure ``rte_device`` got a new field to reference a ``rte_bus``.
It is changing the size of the ``struct rte_device`` and the inherited
device structures of all buses.
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 by 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.
+ Issue has been identified as a GCC defect and reported to GCC community [3]. Further
+ actions will be taken based on the GCC defect result.
