2. DPDK Release 22.07

2.1. New Features

  • Added initial RISC-V architecture support.

    Added EAL implementation for RISC-V architecture. The initial device the porting was tested on was a HiFive Unmatched development board based on the SiFive Freedom U740 SoC. In theory this implementation should work with any rv64gc ISA compatible implementation with MMU supporting a reasonable address space size (U740 uses sv39 MMU).

  • Added Sequence Lock.

    Added a new synchronization primitive: the sequence lock (seqlock). A seqlock allows for low overhead, parallel reads. The DPDK seqlock uses a spinlock to serialize multiple writing threads.

  • Added function to get random floating point number.

    Added the function rte_drand() to provide a pseudo-random floating point number.

  • Added protocol based input color selection for meter.

    Added new functions rte_mtr_color_in_protocol_set(), rte_mtr_color_in_protocol_get(), rte_mtr_color_in_protocol_priority_get(), rte_mtr_meter_vlan_table_update() and updated struct rte_mtr_params and struct rte_mtr_capabilities to support protocol based input color selection for meter.

  • Added Rx queue available descriptors threshold and event.

    Added ethdev API and corresponding driver operations to set Rx queue available descriptors threshold and query for queues that have reached the threshold when a new event RTE_ETH_EVENT_RX_AVAIL_THRESH is received.

  • Added telemetry for module EEPROM.

    Added telemetry command to dump module EEPROM. Added support for module EEPROM information format defined in:

    • SFF-8079 revision 1.7
    • SFF-8472 revision 12.0
