Subject: [dpdk-users] BUG: unable to handle kernel paging request, DPDK
Date: Tue, 21 Feb 2017 16:54:29 -0600 [thread overview]
Message-ID: <CAPO9LfR_n4pXtKt-3eDwMOBsXkHt4HyDZeXLU+Lyjo6PUcqiYg@mail.gmail.com> (raw)
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!
