    SubjectRE: [PATCH v2 01/12] iommu/vt-d: Enumerate the scalable mode capability
    Date

    > The Intel vt-d spec rev3.0 introduces a new translation
    > mode called scalable mode, which enables PASID-granular
    > translations for first level, second level, nested and
    > pass-through modes. At the same time, the previous
    > Extended Context (ECS) mode is deprecated (no production
    > ever implements ECS).
    >
    > This patch adds enumeration for Scalable Mode and removes
    > the deprecated ECS enumeration. It provides a boot time
    > option to disable scalable mode even hardware claims to
    > support it.
