[dpdk-dev] L2FWD uses 'too much' CPU

2014-04-01 Thread Vladimir Medvedkin
Hi, One of the objectives of DPDK is avoiding of interrupts, so application (not only L2FWD) polls NIC infineteley. You can look at programmers guide section 24 "Power Management" and "L3 Forwarding with Power Management Sample Application" in Sample Applications User Guide. Regards, Vladimir.

Thanks for the information. Indeed, it was failing during NIC initialization stage. The problem was due to frequency scaling. After I disable it from bios, I am now able to run dpdk. Thanks again! -hs On Mon, Mar 31, 2014 at 2:46 PM, Shaw, Jeffrey B wrote: > If you read the output that you p

[dpdk-dev] rte_pktmbuf_alloc fails

2014-04-01 Thread Meir Tseitlin
I think I found the problem - it was solved by manually calling rte_pktmbuf_free for each packet. It seems that rte_pktmbuf_free is not automatically called from within rte_eth_tx_burst if packets are sent to pcap device. Is it possible? On Tue, Apr 1, 2014 at 2:08 PM, Meir Tseitlin wrote: > H

[dpdk-dev] rte_pktmbuf_alloc fails

Hello, Ok. Can you help me with something else ? Right now, at a rate of 1.3~1.4 Mpps I am having about 4~5% of packet loss, I wonder if I use my application wth a 10G NIC, will it not be able to cope with more than 1.4 Mpps ? Because by seeing a packet loss I got a little afraid of it. Si

[dpdk-dev] L2FWD uses 'too much' CPU

2014-04-01 Thread Fred Pedrisa
Hi, Why by default L2FWD saturate both cores ? I mean, it seems it keeps wasting cycles due to the infinite loop placed there to check the queues. Which would be the way to improve this and make it to become more efficient ? Sincerely, Fred
