I will look into this. However, can we rely to have access to all
device resources through platform abstractions, for every type of
platform device
The only resources we care about in vfio are mappable regions
and irqs. So, yes I think we can rely on access to those
resources.
It seems
flag to allow binding via sysfs
only

Type1 is arbitrary. It might as well be named brown and this one
can be
blue.
The difference is that type1 seems to refer to hardware that can do
arbitrary 4K page mappings, possibly constrained by an aperture but
nothing else. More than one IOMMU can reasonably fit that. The odds

Yes, kvm_guest_init is a postcore_initcall, which comes after early.
