Isal compress PMD has build failures on Arm platform. As dependent library ISA-L is supported on Arm platform, support of the PMD is expanded to Arm architecture. Fixed build failure caused by architecture specific code, and made the PMD multi architecture compatible. Bugzilla ID: 755 Signed-off-by: Ruifeng Wang <ruifeng.wang@arm.com>

|
|
|
|
Use proper spelling, capitalization and punctuation in all sections.
|
|
|
|

|
|
|
|

|
|
|
|
Refer to the previous release notes for examples.
|
|
|
|
Suggested order in release notes items:
|
|
* Core libs (EAL, mempool, ring, mbuf, buses)
|
|
* Device abstraction libs and PMDs (ordered alphabetically by vendor name)
|
|
- ethdev (lib, PMDs)
|
|
- cryptodev (lib, PMDs)
|
|
- eventdev (lib, PMDs)
|
|
- etc
|
|
* Other libs
|
|
* Apps, Examples, Tools (if significant)

|
=======================================================
|
|
|
|
* **Added auxiliary bus support.**
|
|
|
|
Auxiliary bus provides a way to split function into child-devices
|
|
representing sub-domains of functionality. Each auxiliary device
|
|
represents a part of its parent functionality.
|
|
|
|
* **Added XZ compressed firmware support.**
|
|
|
|
Using ``rte_firmware_read``, a driver can now handle XZ compressed firmware
|
|
in a transparent way, with EAL uncompressing using libarchive if this library
|
|
is available when building DPDK.
|
|
|
|
* **Updated Intel iavf driver.**
|
|
|
|
* Added Tx QoS VF queue TC mapping.
|
|
* Added FDIR and RSS for GTPoGRE, support filter based on GTPU TEID/QFI,
|
|
outer most L3 or inner most l3/l4.
|
|
|
|
* **Updated Intel ice driver.**
|
|
|
|
* In AVX2 code, added the new RX and TX paths to use the HW offload
|
|
features. When the HW offload features are configured to be used, the
|
|
offload paths are chosen automatically. In parallel the support for HW
|
|
offload features was removed from the legacy AVX2 paths.
|
|
* Added Tx QoS TC bandwidth configuration in DCF.
|
|
|
|
* **Added support for Marvell CN10K SoC ethernet device.**
|
|
|
|
* Added net/cnxk driver which provides the support for the integrated ethernet
|
|
device.
|
|
|
|
* **Updated Mellanox mlx5 driver.**
|
|
|
|
* Added support for meter hierarchy.
|
|
* Added devargs options ``allow_duplicate_pattern``.
|
|
* Added matching on IPv4 Internet Header Length (IHL).
|
|
* Added support for matching on VXLAN header last 8-bits reserved field.
|
|
* Optimized multi-thread flow rule insertion rate.
|
|
|
|
* **Added Wangxun ngbe PMD.**
|
|
|
|
Added a new PMD driver for Wangxun 1 Gigabit Ethernet NICs.
|
|
See the :doc:`../nics/ngbe` for more details.
|
|
|
|
* **Updated Solarflare network PMD.**
|
|
|
|
Updated the Solarflare ``sfc_efx`` driver with changes including:
|
|
|
|
* Added COUNT action support for SN1000 NICs
|
|
|
|
* **Updated Intel QuickAssist crypto PMD.**
|
|
|
|
Added fourth generation of QuickAssist Technology(QAT) devices support.
|
|
Only symmetric crypto has been currently enabled, compression and asymmetric
|
|
crypto PMD will fail to create.
|
|
|
|
* **Added support for Marvell CNXK crypto driver.**
|
|
|
|
* Added cnxk crypto PMD which provides support for an integrated
|
|
crypto driver for CN9K and CN10K series of SOCs. Support for
|
|
symmetric crypto algorithms is added to both the PMDs.
|
|
* Added support for lookaside protocol (IPsec) offload in cn10k PMD.
|
|
* Added support for asymmetric crypto operations in cn9k and cn10k PMD.
|
|
|
|
* **Updated Marvell OCTEON TX crypto PMD.**
|
|
|
|
Added support for crypto adapter OP_FORWARD mode.
|
|
|
|
* **Updated ISAL compress device PMD.**
|
|
|
|
The ISAL compress device PMD now supports Arm platforms.
|
|
|
|
* **Added Baseband PHY CNXK PMD.**
|
|
|
|
Added Baseband PHY PMD which allows to configure BPHY hardware block
|
|
comprising accelerators and DSPs specifically tailored for 5G/LTE inline
|
|
usecases. Configuration happens via standard rawdev enq/deq operations. See
|
|
the :doc:`../rawdevs/cnxk_bphy` rawdev guide for more details on this driver.
|
|
|
|
* **Added support for Marvell CN10K, CN9K, event Rx/Tx adapter.**
|
|
|
|
* Added Rx/Tx adapter support for event/cnxk when the ethernet device requested
|
|
is net/cnxk.
|
|
* Added support for event vectorization for Rx/Tx adapter.
|
|
|
|
* **Added cppc_cpufreq support to Power Management library.**
|
|
|
|
Added support for cppc_cpufreq driver which works on most arm64 platforms.
|
|
|
|
* **Added multi-queue support to Ethernet PMD Power Management**
|
|
|
|
The experimental PMD power management API now supports managing
|
|
multiple Ethernet Rx queues per lcore.

|
|
truncation.
|
|
|
|
* eal: ``rte_power_monitor`` and the ``rte_power_monitor_cond`` struct changed
|
|
to use a callback mechanism.
|
|
|
|
* rte_power: The experimental PMD power management API is no longer considered
|
|
to be thread safe; all Rx queues affected by the API will now need to be
|
|
stopped before making any changes to the power management scheme.
