FWIW, you absolutely need iommu suport in order to make thunderbolt even
somewhat secure. So polishing and enabling iommu support for amd64 would
have to come first.

Hi Tom,
I share your understanding that Thunderbolt has a lower security
profile due to TB having dynamic memory addresses access while USB does
not. I presume the engineering idea is that the IOMMU (when enabled and
properly configured) should uphold memory safety.
Remember though you have this

Hi tech@,
If anyone is interested in implementing Thunderbolt support for
OpenBSD, I'd like to donate some PCIe expansion Thunderbolt 3 enclosure
and M.2 NVMe SSD Thunderbolt 3 enclosure as appropriate, if so please
let me know.

Hi Joseph,All
There are some PCI-E attack surfaces that might need to be considered...
perhaps the availability of more devices with thunderbolt connections make
PCI-E / DMA Attacks more viable and hence more prevalent.
