Hi Jens, <snip>
> 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 > <snip> This patch set does not apply to the current master branch, could you rebase please to the latest master branch.
