Just wanted to wrap up this thread by confirming what Alex said is true (in
case anyone else is interested in this topic in the future). After enabling
IOMMU tracing on the host I was able to confirm that IOMMU mappings were,
in fact, being created properly to map the gPA to hPA of both devices'

I'm trying to use the vfio-pci driver to pass-through two PCIe endpoint
devices into a VM. On the host, each of these PCIe endpoint devices is in
its own IOMMU group. From inside the VM, I would like to perform P2P DMA
operations. So basically, programming the DMA engine of one of the devices
