This is a userspace inteface, so use a generic name like iommu. We also
need a KVM_CAP so userspace can check whether an iommu is present or not.
How about this?
Looks fine.

That only detects if the headers have the flag, not if the kernel

Which means we expose KVM_CAP_IOMMU only if one was detected?
Yes.
How to do this
correctly?
I don't

Also, is KVM_CAP_foo needed for this? This is the only #define that'll be
used and we can simply do something like

This patch enables pci device assignment based on VT-d support.
When a device is assigned to the guest, the guest memory is pinned and
the mapping is updated in the VT-d IOMMU.
