Description
I am running OpenIndiana Hipster when I run the Device Driver Utility it reports that the following AMD components are unknown devices.

OpenIndiana Hipster is reporting that it failed to attach the AMD IOMMU could this be related to the Starship/Matisse PCIe Dummy Function?
In the attached extract of /var/adm/messages it reports
May 4 07:44:42 tesla genunix: [ID 596552 kern.info] Reading Intel IOMMU boot options
May 4 07:44:42 tesla rootnex: [ID 349649 kern.info] npe0 at root: space 0 offset 0
May 4 07:44:42 tesla genunix: [ID 936769 kern.info] npe0 is /pci@0,0
If the Intel IOMMU options have been read then would it be able to attach the AMD IOMMU?

Couple notes here:
- On AMD systems in general (Rome, Milan, etc.) you'll find devices without drivers. For some of these like the dummy ports, that's expected.
- No one has written a driver for the PSP encryption/decryption controller there because there are no docs.
- Currently the IOMMU on AMD isn't supported.
- On Zen2/3 systems you'll actually find that the device we care about for enumerating subsequent devices are the actual host bridges. That is generally on Zen 2 pciex1022,1484. The dummies are just dummies.
