DPDKInfo
DPDKInfo — Click element; Set DPDK global parameters.
DPDKInfo([keywords NB_MBUF, MBUF_SIZE, RX_PTHRESH, etc.])
Ports: none
Set Intel's DPDK global parameters used by FromDPDKDevice and ToDPDKDevice elements. See DPDK documentation for details.
Keyword arguments:
-
NB_MBUF — Integer. Number of message buffers to allocate. Defaults to 65536.
-
MBUF_SIZE — Integer. Size of a message buffer in bytes. Defaults to 2048 + RTE_PKTMBUF_HEADROOM.
-
MBUF_CACHE_SIZE — Integer. Number of message buffer to keep in a per-core cache. It should be such that NB_MBUF modulo MBUF_CACHE_SIZE == 0. Defaults to 256.
-
RX_PTHRESH — Integer. RX prefetch threshold. Defaults to 8.
-
RX_HTHRESH — Integer. RX host threshold. Defaults to 8.
-
RX_WTHRESH — Integer. RX write-back threshold. Defaults to 4.
-
TX_PTHRESH — Integer. TX prefetch threshold. Defaults to 36.
-
TX_HTHRESH — Integer. TX host threshold. Defaults to 0.
-
TX_WTHRESH — Integer. TX write-back threshold. Defaults to 0.
-
MEMPOOL_PREFIX — String. Prefix for the mempool name. Use this to get a predictable
mempool name and attach secondary processes. -
DEF_RING_NDESC — Integer. Number of frame descriptors in the ring buffer. Used for interprocess communication. Defaults to 1024.
-
DEF_BURST_SIZE — Integer. Number of frames to read/write from/to a DPDK device. Defaults to 32.
-
RING_FLAGS — Integer. Parameters to pass to a ring-based DPDK process communication. Defaults to 0.
-
RING_SIZE — Integer. The size of the ring used for DPDK inter-process communication. Defaults to 64.
-
RING_POOL_CACHE_SIZE — Integer. The size of the message buffer for DPDK inter-process communication. Defaults to 32.
-
RING_PRIV_DATA_SIZE — Integer. The size of the private memory area for a pair of interconnected DPDK process. Defaults to 0 as there is no need to share something privately.
This element is only available at user level, when compiled with DPDK support.
