Hi Rami,
Yes, I mean “uio_pci_generic” kernel module.
I will update the change accordingly.
Thanks.

Hi Tone,

please make
The three kernel modules which can be used for DPDK binding are vfio-pci,
uio_pci_generic and igb_uio. Don't you mean here uio_pci_generic ?

When binding the devices used by DPDK to the "uio-pci" kernel module,

because of the virtual / physical address mapping.
The patch clarifies the IOMMU configuration on both x86_64 and arm64
