SubjectRE: [PATCH v2 01/12] iommu/vt-d: Enumerate the scalable mode capability
Date
> From: Lu Baolu [mailto:baolu.lu@linux.intel.com]
> Sent: Thursday, August 30, 2018 9:35 AM
>
> 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.
