Hello,
I know the b:d.f of my device. However, I am not able to tell if this
specific device is mapped to the right IOMMU. In my specific system there are
two IOMMU, right? If so, I am not sure how I can get the mapping info from
the output of /proc/iomem.
Regards,
Ahmed.

please try:
1) lspci -vs THE_PCI_ID
2) cat /proc/iomem
