Component Type: kbuild config

Description: Enable Intel IOMMU scalable mode by default

More info: Selecting this option will enable by default the scalable mode if hardware presents the capability. The scalable mode is defined in VT-d 3.0. The scalable mode capability could be checked by reading /sys/devices/virtual/iommu/dmar*/intel-iommu/ecap. If this option is not selected, scalable mode support could also be enabled by passing intel_iommu=sm_on to the kernel. If not sure, please use the default value.
