hello devs, I am using DPDK 1.5.0 and trying to use KNI interface to measure throughput through it
------------------------------------------------------------------------------------------------------------ I have machine with 2 lcores and 2 physical interface, and in running kni sample application --config parameter we are supposed to give 1)port no, 2)lcore_rx, 3)lcore_tx, right? so can it be possible to give same lcore no. for both ports, like kni -c 0x3 -n 4 -- -P -p 0x3 --config"(0,0,1),(1,0,1)" As i have tried and after running this two interface vEth0 and vEth1 is created, but when i am giving ip with ifconfig to vEth1 then it is showing the below message ... SIOCSIFFLAGS: Timer expired, while i am able to bring up the the vEth0 interface successfully. ----------------------------------------------------------------------------------------------------- i am pasting some details which prints while running the application ... Checking link status .....done Port 0 Link Up - speed 1000 Mbps - full-duplex Port 1 Link Up - speed 1000 Mbps - full-duplex APP: Lcore 1 is writing to port 0 APP: Lcore 0 is reading from port 0 and here in last two line Lcore 1 and Lcore 0 is writting and reading for port 0 and may be therefore i am able to bring up the vEth0. and there is no core for port 1 so it is failing. --------------------------------------------------------------------------------------------------------- So my question is why can't we use same lcores for reading and writing for both ports, does DPDK restricts using same lcores for 2 ports (as it seems), and if so, then why?? Thanks in advance C R
