Intel vt-d rev3.0 [1] introduces a new translation mode called
'scalable mode', which enables PASID-granular translations for
first level, second level, nested and pass-through modes. The
vt-d scalable mode is the key ingredient to enable Scalable I/O
Virtualization (Scalable IOV) [2] [3], which al
