Subject: [dpdk-dev] [PATCH v3 0/2] testpmd: simulating noisy host
environment
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.
Comments are appreciated.
regards,
Jens

This patch set does not apply to the current master branch, could you rebase
please to the latest master branch.
As Jens isn't available until mid-July, I'll take care to rebase it.
Thanks for the notification,
Maxime
