What exactly do you mean? Why do you need to write to vendo

This commit introduces support for an UNSAFE, no-IOMMU mode in the
vhost-vdpa driver. When enabled, this mode provides no device isolation,
no DMA translation, no host kernel protection, and cannot be used for
device assignment to virtual machines. It requires RAWIO permissions
and will taint the k
