Subject: [dpdk-users] Output to /dev/console provokes packet loss?
Date: Fri, 12 Feb 2016 13:32:07 +0100 [thread overview]
Message-ID: <87pow2yurc.fsf@obh-fbu.ti.telenor.net> (raw)
Hi,
I'm running a DPDK application on HP ProLiant DL360 Gen9, BIOS P89 and
CentoS 7.2.1511 with a 10Gb 2-port 560SFP+ Adapter/ixgbe.
A periodically packet loss (increasing stats.imissed) was traced back
to log messages to /dev/console. A simple loop like this provoked the
packet loss:
while :; do echo "foo bar" > /dev/console; done
I saw the same ting when running stock kernel and running standard
iperf so my guess is a problem with the BIOS / motherboard / ILO and
not DPDK. Does anybody have any other hypothesis?
Regards,
Ole Bjørn Hessen.
Telenor.
