If that's the case, then we should *definitely* have that IOMMU_PASID kind of config option.
Then IOMMU_SVA - that needs PASID - can "select" it, but any other use - that doesn't bother about SVA but might want PASID for its own nefarious purposes - can also select it.
This is why we have config options. Not just for legibility, but also for "there are different scenarios".
