Intel x553 vfio-pci support

[infinitydon]

Hi,

Please I will like to confirm if vfio-pci can be used with Intel Corporation Ethernet Connection X553?

I tried the following to bind it using dpdk-devbind.py (on the host directly):

root@proxmox-baremetal:~# ./dpdk-devbind.py -b vfio-pci 0000:07:00.0
[ 313.210908] ixgbe 0000:07:00.0: complete

But somewhere in DMESG the following error came up:

[ 559.634879] vfio-pci 0000:07:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xbeef

I also did a PCI passthrough of the same interface into a VM and tried to bind it:

root@proxmox-vm:/home/chris# ./dpdk-devbind.py -b vfio-pci 00:10.0
Error: bind failed for 0000:00:10.0 - Cannot bind to driver vfio-pci
Error: unbind failed for 0000:00:10.0 - Cannot open /sys/bus/pci/drivers//unbind
root@proxmox-vm:/home/chris#

Hi,

I have been able to resolve the issue, I ended installing upstream ubuntu distro.

Also inside my VMs, the following command was the only that made possible to able to bind the passed through interfaces to vfio-pci.

sudo echo Y | sudo tee /sys/module/vfio/parameters/enable_unsafe_noiommu_mode
