Subject: [dpdk-dev] [virtio] virtio-net PMD cannot be used on Ubuntu 16.10
Date: Thu, 24 Nov 2016 15:44:04 +0000 [thread overview]
Message-ID: <DB5PR06MB168650FD160E86F2FEB9E874C0B60@DB5PR06MB1686.eurprd06.prod.outlook.com> (raw)
Hello,
While I (almost) never had a problem with testpmd, Ubuntu 16.10 make it fail:
$ sudo ./testpmd -c 0x3 -n1 --no-huge -- --disable-hw-vlan --disable-rss -i --rxq=1 --txq=1 --rxd=256 --txd=256
EAL: Detected 4 lcore(s)
EAL: Probing VFIO support...
EAL: WARNING: cpu flags constant_tsc=yes nonstop_tsc=no -> using unreliable clock cycles !
EAL: PCI device 0000:00:08.0 on NUMA socket -1
EAL: probe driver: 1af4:1000 net_virtio
EAL: Error - exiting with code: 1
Cause: Requested device 0000:00:08.0 cannot be used
This boils down to virtio_pci.c
if (!check_vq_phys_addr_ok(vq))
return -1;
which fails because vq is 0x7ffff7172700 and is greater than 16TB.
is there an issue or do I configure something badly?
I used the same method to test on 14.04 15.10 and 16.04 without problems.
Huge pages are configured and are used by DPDK.
