Subject: [dpdk-ci] Intel VFIO-PCI Driver Error -22
Date: Thu, 8 Oct 2020 12:51:33 -0400 [thread overview]
Message-ID: <CAOeXdvYwEWjQvjuBC1ZFuiceE8Twry3b7ZSJ7ftRJuueC6y9rQ@mail.gmail.com> (raw)
Hi everyone,
I am having issues trying to bind both Intel Niantic and Fortville
NICs over to VFIO-PCI.
The machines are running Ubuntu 18.04 with kernel 4.15.0-55.
The dpdk-devbind.py tool outputs "Cannot bind to driver vfio-pci" and
"Cannot open /sys/bus/pci/drivers//unbind".
The dmesg output contains "vfio-pci: probe of [PCI Address] failed
with error -22" whenever I try to bind it.
Both machines have "intel_iommu=on iommu=pt" in their kernel parameters.
Thanks,
Brandon
