Yes. We don't need to check it every time. Check once and save the
result during boot is enough.

If Intel IOMMU runs in caching mode, a.k.a. virtual IOMMU, the
IOMMU driver should rely on the emulation software to allocate
and free PASID IDs. The Intel vt-d spec revision 3.0 defines a

a virtual command register
