Subject: [dpdk-dev] [PATCH v4 0/2] testpmd: simulating noisy host environment
Date: Sat, 23 Jun 2018 10:08:38 +0200 [thread overview]
Message-ID: <20180623080840.315-1-maxime.coquelin@redhat.com> (raw)
This forth version is a rebase of Jen's v3, fixing meson build
and checkpatch errors.
Some checkpatch warnings remain to keep consistency with other
code.
This series adds a new forwarding mode 'noisy'. It proposes
enhancements to testpmd to simulate more realistic behavior of a guest
machine engaged in receiving and sending packets performing Virtual
Network Function (VNF).
The goal is to enable simple of measuring performance impact on cache and
memory footprint utilization from various VNF co-located on the
same host machine.
This series of patches adds the new command line switches to
testpmd:
--noisy-buffersize-before-sending [packet numbers]
Keep the mbuf in a FIFO and forward the over flooding packets from the
FIFO. This queue is per TX-queue (after all other packet processing).
--noisy-flush-timeout [delay]
Flush the packet queue if no packets have been seen during
[delay]. As long as packets are seen, the timer is reset.
Options to simulate route lookups:
--noisy-memory-footprint [size]
Size of the VNF internal memory (MB), in which the random
read/write will be done, allocated by rte_malloc (hugepages).
--noisy-nb-rnd-write [num]
Number of random writes in memory per packet should be
performed, simulating hit-flags update. 64 bits per write,
all write in different cache lines.
--noisy-nb-rnd-read [num]
Number of random reads in memory per packet should be
performed, simulating FIB/table lookups. 64 bits per read,
all write in different cache lines.
--noisy-nb-rnd-read-write [num]
Number of random reads and writes in memory per packet should
be performed, simulating stats update. 64 bits per read-write, all
reads and writes in different cache lines.
