My application already uses igb_uio.
I am trying to change for vfio-pci in order to run my application without
root permissions.
I fixed the issue with the bind by adding this: "intel_iommu=on iommu=pt"
to the grub file.
Now i having another problem:

EAL:   0000:06:00.0 failed to select IOMMU type


dmesg output:

[11597.560394] vfio-pci 0000:06:00.1: Device is ineligible for IOMMU domain
attach due to platform RMRR requirement.  Contact your platform vendor.
