Subject: [dpdk-users] facing issue with testpmd with ovs in dpdk17.0.2, link is always down with 2m hugepage
Date: Tue, 22 Dec 2020 04:50:14 +0530	[thread overview]
Message-ID: <CAJ+HfNbfd7s+vF0Foat2BsgzOLufsR5B2tFO==b0H3EReD2tRA@mail.gmail.com> (raw)

Hi,

We are running testpmd with 150MB(2M huge pages) with OVS DPDK (17.0.2) but
ran into issues as pmd interfaces are shown as link down.


./testpmd -c 0x3 -n 4 *--socket-mem 150* --no-pci

Same thing works fine with 1024m ( 1G hugepage). Our mbuf doesn't change,
it is around 35m in both cases.

Is there some argument missing in testpmd, as in the non working case queue
is getting disabled.

Regards,
