Subject: [dpdk-dev] A bug in DPDK ENA driver
Date: Tue, 19 Jun 2018 21:23:56 +0300 [thread overview]
Message-ID: <CAA9qGqUrEtu+O25B2HDZFQMZYoboJtmF3kYn4sOPPzNdh2Pw5g@mail.gmail.com> (raw)
Hi! I’m trying to launch NFF-GO (https://github.com/intel-go/nff-go)
on AWS instances and faced a problem (Program received signal SIGFPE,
Arithmetic exception.) which was caused by:
0x00000000006f703c in ena_rss_init_default (adapter=0x7fffef399200)
at /home/ec2-user/projects/src/github.com/intel-go/nff-go/dpdk/dpdk-18.02/drivers/net/ena/ena_ethdev.c:571
571 val = i % nb_rx_queues;
nb_rx_queues is 0, cause our application does not receive and we do
not use rx queues. Could you please fix it by wrapping with 0 check
(and making val 0 if 0 queues) before division?
Best regards,
Kolistratova Daria
