|
|
=========================================================
|
|
|
|
* **Updated the EAL Pseudo-random Number Generator.**
|
|
|
|
The lrand48()-based rte_rand() function is replaced with a
|
|
DPDK-native combined Linear Feedback Shift Register (LFSR)
|
|
pseudo-random number generator (PRNG).
|
|
|
|
This new PRNG implementation is multi-thread safe, provides
|
|
higher-quality pseudo-random numbers (including full 64 bit
|
|
support) and improved performance.
|
|
|
|
In addition, <rte_random.h> is extended with a new function
|
|
rte_rand_max() which supplies unbiased, bounded pseudo-random
|
|
numbers.
|
|
|
|
* **Updated the bnxt PMD.**
|
|
|
|
Updated the bnxt PMD. The major enhancements include:
|
|
|
|
* Performance optimizations in non-vector Tx path
|
|
* Added support for SSE vector mode
|
|
* Updated HWRM API to version 1.10.0.74
|
|
|
|
* **Added support for Broadcom NetXtreme-E BCM57500 Ethernet controllers.**
|
|
|
|
Added support to the bnxt PMD for the BCM57500 (a.k.a. "Thor") family
|
|
of Ethernet controllers. These controllers support link speeds up to
|
|
200Gbps, 50G PAM-4, and PCIe 4.0.
|
|
|
|
* **Added hinic PMD.**
|
|
|
|
Added the new ``hinic`` net driver for Huawei Intelligent PCIE Network
|
|
Adapters based on the Huawei Ethernet Controller Hi1822.
|
|
See the :doc:`../nics/hinic` guide for more details on this new driver.
|
|
|
|
* **Updated the ice driver.**
|
|
|
|
Updated ice driver with new features and improvements, including:
|
|
|
|
* Enabled Tx outer/inner L3/L4 checksum offload.
|
|
* Enabled generic filter framework and supported switch filter.
|
|
* Supported UDP tunnel port add.
|
|
|
|
* **Updated Solarflare network PMD.**
|
|
|
|
Updated the Solarflare ``sfc_efx`` driver with changes including:
|
|
|
|
* Added support for Rx interrupts.
|
|
|
|
* **Added memif PMD.**
|
|
|
|
Added the new Shared Memory Packet Interface (``memif``) PMD.
|
|
See the :doc:`../nics/memif` guide for more details on this new driver.
|
|
|
|
* **Updated the AF_XDP PMD.**
|
|
|
|
Updated the AF_XDP PMD. The new features include:
|
|
|
|
* Enabled zero copy through mbuf's external memory mechanism to achieve
|
|
high performance
|
|
* Added multi-queue support to allow one af_xdp vdev with multiple netdev
|
|
queues
|
|
* Enabled need_wakeup feature which can provide efficient support for case
|
|
that application and driver executing on the same core.
|
|
|
|
* **Enabled infinite Rx in the PCAP PMD.**
|
|
|
|
Added an infinite Rx feature which allows packets in the Rx PCAP of a PCAP
|
|
device to be received repeatedly at a high rate. This can be useful for quick
|
|
performance testing of DPDK apps.
|
|
|
|
* **Added Intel QuickData Technology PMD**
|
|
|
|
The PMD for Intel\ |reg| QuickData Technology, part of
|
|
Intel\ |reg| I/O Acceleration Technology `(Intel I/OAT)
|
|
<https://www.intel.com/content/www/us/en/wireless-network/accel-technology.html>`_,
|
|
allows data copies to be done by hardware instead
|
|
of via software, reducing cycles spent copying large blocks of data in
|
|
applications.
|
|
|
|
* **Introduced NTB PMD.**
|
|
|
|
Added a PMD for Intel NTB (Non-transparent Bridge). This PMD implemented
|
|
handshake between two separate hosts and can share local memory for peer
|
|
host to directly access.
|
|
|
|
* **Updated telemetry library for global metrics support.**
|
|
|
|
Updated ``librte_telemetry`` to fetch the global metrics from the
|
|
``librte_metrics`` library.
|
|
|
|
* **Added new telemetry mode for l3fwd-power application.**
|
|
|
|
Added telemetry mode to l3fwd-power application to report
|
|
application level busyness, empty and full polls of rte_eth_rx_burst().
|

|
Removed Items
|
|
-------------
|
|
|
|
.. This section should contain removed items in this release. Sample format:
|
|
|

|
|
in the past tense.

|
|
Also, make sure to start the actual text at the margin.
|
|
=========================================================
|
|
|
|
* Removed KNI ethtool, CONFIG_RTE_KNI_KMOD_ETHTOOL, support.
|
|
|
|
* build: armv8 crypto extension is disabled.

API Changes
|
|
-----------
|
|
|
|
.. This section should contain API changes. Sample format:
|
|
|
|
* sample: Add a short 1-2 sentence description of the API change
|
|
which was announced in the previous releases and made in this release.
|
|
Start with a scope label like "ethdev:".
|
|
Use fixed width quotes for ``function_names`` or ``struct_names``.
|
|
Use the past tense.
|
|
|
|
This section is a comment. Do not overwrite or remove it.
|
|
Also, make sure to start the actual text at the margin.
|
|
=========================================================
|
|
|
|
* The ``rte_mem_config`` structure has been made private. The new accessor
|
|
``rte_mcfg_*`` functions were introduced to provide replacement for direct
|
|
access to the shared mem config.
|
|
|
|
* The network structures, definitions and functions have
|
|
been prefixed by ``rte_`` to resolve conflicts with libc headers.
|
|
|
|
* malloc: The function ``rte_malloc_set_limit`` was never implemented
|
|
is deprecated and will be removed in a future release.
|
|
|
|
* eventdev: No longer marked as experimental.
|
|
|
|
The eventdev functions are no longer marked as experimental, and have
|
|
become part of the normal DPDK API and ABI. Any future ABI changes will be
|
|
announced at least one release before the ABI change is made. There are no
|
|
ABI breaking changes planned.
|
|
|
|
|
|
ABI Changes
|
|
-----------
|
|
|
|
.. This section should contain ABI changes. Sample format:
|
|
|
|
* sample: Add a short 1-2 sentence description of the ABI change
|
|
which was announced in the previous releases and made in this release.
|
|
Start with a scope label like "ethdev:".
|
|
Use fixed width quotes for ``function_names`` or ``struct_names``.
|
|
Use the past tense.

|
|
=========================================================
|
|
|
|
* eventdev: Event based Rx adapter callback
|
|
|
|
The mbuf pointer array in the event eth Rx adapter callback
|
|
has been replaced with an event array. Using
|
|
an event array allows the application to change attributes
|
|
of the events enqueued by the SW adapter.
|
|
|
|
The callback can drop packets and populate
|
|
a callback argument with the number of dropped packets.
|
|
Add a Rx adapter stats field to keep track of the total
|
|
number of dropped packets.
|
|
|
|
|
|
