I am trying to run the kni sample application from dpdk, so I did the following steps:
1. Compiled the program 2. Allocated 256 hugepages 3. Unbinded the ethernet port from the ixgbe driver and binded them to the igb_uio driver When I tried to run the program, it crashed, with the following error: BUG: Unable to handle kernel paging request at xxxxxxx So I tried to find the line which causes the crash. I narrowed it down to line 260: num = rte_kni_tx_burst(p->kni[i], pkts_burst, nb_rx); Which is part of function kni_ingress. It looks like it crashes when doing fifo read/write, but I'm not sure why. Any idea on what could be wrong or any suggestion would be appreciated!
