Test/Enable VT-d support
Closed, ResolvedPublic

Description

VT-d support needs to be specifically enabled by coreboot. VT-x can be enabled in software with a 'wrmsr' command, but VT-d requires iommu to be enabled from coreboot and DMAR ACPI tables to be created.

Note that gm45, and ivybridge has support for VT-d, it just needs to be ported to skylake.
