[dpdk-dev] Weird behavior of DPDK - ongoing problem

Hi guys, I am still struggling to find a solution for a problem each time I face from different angle (already wrote few posts). Now I think it is some kind of DMA problem. I am modifying l2fwd example to collect packet flow from high speed ethernet device and store it in file, this is why I use

[dpdk-dev] Still rte_pktmbuf_alloc problems

I am modifying l2fwd example to inject additional packets. I am successfully allocating mbufs with rte_pktmbuf_alloc, but weird problems started to occur (feels likes concurrency problems). I enabled DEBUGs in config file and now my application started crashing on: PANIC in rte_mbuf_sanity_check

[dpdk-dev] rte_pktmbuf_alloc fails

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
