Subject: [dpdk-dev] dpdk 1.8.0 disable burst problem
Date: Thu, 10 Sep 2015 21:54:26 +0800 (CST) [thread overview]
Message-ID: <278d006e.109ef.14fb78933fa.Coremail.zhangwqh@126.com> (raw)
Hi all,
I am using the dpdk example dpdk-1.8.0/examples/multi_process/client_server_mp on ubuntu 14.04. I need to disable the batch. At first, I just change the macro in mp_server/main.c and mp_client/client.c
#define PACKET_READ_SIZE 32 to 1
The server and the client can not receive any packets. Almost of the packets are counted to err from the port stat.
Port:0, rx:511, rx_err:33011882, rx_nombuf:0, tx:0, tx_err:0
Port:0, rx_rate:0, rx_err_rate:782253,rx_nombuf_rate:0, tx_rate:0, tx_err_rate:0
However, DPDK 1.4.1 works only changing the batch size from 32 to 1 in server and client.
What I did in the next step is
disable the vector PMD burst on DPDK 1.8.0 version.
disable the macro from config file
CONFIG_RTE_IXGBE_INC_VECTOR=n
However, nothing is changed. Port still reports packets errs.
Can anyone help to look at this problem? I will be very appreciated.
BTW, why DPDK 1.4.1 can not be compiled on ubuntu 14.04?
