RE: [Xen-devel] [PATCH] [VTD] Add 'force_iommu' option
ACKed-by: Joseph Cihula <joseph.cihula@xxxxxxxxx>
This patch is needed to maintain trust in Xen when it is launched using
Intel(R) Trusted Execution Technology, as it will be launched with DMA
protection and needs to fail securely if that protection cannot be
maintained.

Subject: [Xen-devel] [PATCH] [VTD] Add 'force_iommu' option
For security reasons, add 'force_iommu' option to ensure that it should
not be possible under any conditions to boot Xen w/o VT-d being enabled.
This would only be specified by users that really want the added
security.
