1. DPDK Release 20.11
1.1. New Features
Added write combining store APIs.
Added
rte_write32_wc
andrte_write32_wc_relaxed
APIs that enable write combining stores (depending on architecture). The functions are provided as a generic stub and x86 specific implementation.Added prefetch with intention to write APIs.
Added new prefetch function variants e.g.
rte_prefetch0_write
, which allow the programmer to prefetch a cache line and also indicate the intention to write.Added the rte_cldemote API.
Added a hardware hint CLDEMOTE, which is similar to prefetch in reverse. CLDEMOTE moves the cache line to the more remote cache, where it expects sharing to be efficient. Moving the cache line to a level more distant from the processor helps to accelerate core-to-core communication. This API is specific to x86 and implemented as a stub for other architectures.
Added support for limiting maximum SIMD bitwidth.
Added a new EAL config setting
max_simd_bitwidth
to limit the vector path selection at runtime. This value can be set by apps using therte_vect_set_max_simd_bitwidth
function, or by the user with EAL flag--force-max-simd-bitwidth
.Added zero copy APIs for rte_ring.
For rings with producer/consumer in
RTE_RING_SYNC_ST
,RTE_RING_SYNC_MT_HTS
modes, these APIs split enqueue/dequeue operation into three phases (enqueue/dequeue start, copy data to/from ring, enqueue/dequeue finish). Along with the advantages of the peek APIs, these provide the ability to copy the data to the ring memory directly without the need for temporary storage.Updated CRC modules of the net library.
Added runtime selection of the optimal architecture-specific CRC path.
Added optimized implementations of CRC32-Ethernet and CRC16-CCITT using the AVX512 and VPCLMULQDQ instruction sets.
Introduced extended buffer description for receiving.
Added the extended Rx buffer description for Rx queue setup routine providing the individual settings for each Rx segment with maximal size, buffer offset and memory pool to allocate data buffers from.
Added the FEC API, for a generic FEC query and config.
Added the FEC API which provides functions for query FEC capabilities and current FEC mode from device. An API for configuring FEC mode is also provided.
Added thread safety to rte_flow functions.
Added the
RTE_ETH_DEV_FLOW_OPS_THREAD_SAFE
device flag to indicate whether a PMD supports thread safe operations. If the PMD doesn’t set the flag, the rte_flow API level functions will protect the flow operations with a mutex.Added flow-based traffic sampling support.
Added a new action
RTE_FLOW_ACTION_TYPE_SAMPLE
that will sample the incoming traffic and send a duplicated traffic with the specified ratio to the application, while the original packet will continue to the target destination.The packets sampling is ‘1/ratio’. A ratio value set to 1 means that the packets will be completely mirrored. The sample packet can be assigned with a different set of actions than the original packet.
Added support of shared action in flow API.
Added shared action support to use single flow actions in multiple flow rules. An update to the shared action configuration alters the behavior of all flow rules using it.
Added a new action:
RTE_FLOW_ACTION_TYPE_SHARED
to use shared action as a flow action.Added new flow APIs to create/update/destroy/query shared actions.
Added support to flow rules to allow private PMD items/actions.
Flow rule verification has been updated to accept private PMD items and actions.
Added a generic API to offload tunneled traffic and restore missed packets.
Added a new hardware independent helper to the flow API that offloads tunneled traffic and restores missed packets.
Updated the ethdev library to support hairpin between two ports.
New APIs have been introduced to support binding / unbinding of 2 ports in a hairpin configuration. The hairpin Tx part flow rules can be inserted explicitly. A new API has been added to get the hairpin peer ports list.

, where the hardware fills an area of memory with a repeating pattern.Added a per-device configuration flag to disable management of user-provided completion handles.
Renamed the
rte_ioat_do_copies()

rte_ioat_fence()

Updated the pipeline library for alignment with the P4 language.
Added a new Software Switch (SWX) pipeline type that provides more flexibility through APIs and feature alignment with the P4 language. Some enhancements are:
The packet headers, meta-data, actions, tables and pipelines are dynamically defined instead of selected from a pre-defined set.

pci_map_resource
andpci_unmap_resource
) and moved it to the PCI bus driver along with the PCI resources lists and associated structures (pci_map
,pci_msix_table

RTE_CRYPTO_AEAD_LIST_END
fromenum rte_crypto_aead_algorithm
,RTE_CRYPTO_CIPHER_LIST_END
fromenum rte_crypto_cipher_algorithm
andRTE_CRYPTO_AUTH_LIST_END
fromenum rte_crypto_auth_algorithm
are removed to avoid future ABI breakage while adding new algorithms.scheduler: Renamed functions
rte_cryptodev_scheduler_slave_attach
,rte_cryptodev_scheduler_slave_detach

touint8_t
so that a new fieldsdap_enabled
can be added to support SDAP.security: The API
rte_security_session_create
is updated to take two mempool objects: one for session and other for session private data. So the application need to create two mempools and get the size of session private data using APIrte_security_session_get_size
for private session mempool.ipsec:
RTE_SATP_LOG2_NUM
has been dropped fromenum
and subsequently movedrte_ipsec
lib from experimental to stable.baseband/fpga_lte_fec: Renamed function

rte_rawdev_queue_setup()
,rte_rawdev_queue_conf_get()
,rte_rawdev_info_get()
andrte_rawdev_configure()
, allowing limited driver type-checking and ABI compatibility.rawdev: Changed the return type of the function
rte_dev_info_get()
and the functionrte_rawdev_queue_conf_get()
fromvoid
toint
allowing the return of error codes from drivers.rawdev: The running of a drivers
selftest()
function can now be done using therawdev_autotest
command in thedpdk-test
binary. This command now calls the self-test function for each rawdev found on the system, and does not require a specific command per device type. Following this change, theioat_rawdev_autotest
command has been removed as no longer needed.raw/ioat: As noted above, the
rte_ioat_do_copies()
andrte_ioat_completed_copies()
functions have been renamed torte_ioat_perform_ops()
andrte_ioat_completed_ops()
respectively.stack: the experimental tag has been dropped from the stack library, and its interfaces are considered stable as of DPDK 20.11.
bpf:
RTE_BPF_XTYPE_NUM
has been dropped fromrte_bpf_xtype
.gso: Changed
rte_gso_segment
behaviour and return value:pkt
is not saved topkts_out[0]
if not GSOed.Return 0 instead of 1 for the above case.
pkt
is not freed, no matter whether it is GSOed, leaving to the caller.
acl:
RTE_ACL_CLASSIFY_NUM
enum value has been removed. This enum value was not used inside DPDK, while it prevented the addition of new classify algorithms without causing an ABI breakage.sched: Added
subport_profile_id
as an argument to functionrte_sched_subport_config
.sched: Removed
tb_rate
,tc_rate
,tc_period
andtb_size

eth_rx_descriptor_status_t rx_descriptor_status;
eth_tx_descriptor_status_t tx_descriptor_status;
struct eth_dev_ops
is no longer accessible by applications, which was already an internal data structure.ethdev
internal functions are marked with__rte_internal
tag.Added extensions’ attributes to struct
rte_flow_item_ipv6
. A set of additional values added to struct, indicating the existence of every defined extension header type. Applications should use the new values for identification of existing extensions in the packet header.Added fields
