[Xen-devel] [PATCH] IOMMU: Add two generic functions to vendor neutral interface
Hi, This patch adds 2 generic functions into the vendor neutral iommu interface, The reason is that from changeset 19732, there is only one global flag "iommu_enabled" that controls iommu enablement for both vtd and amd systems, so we need different code paths for vtd and amd iommu systems if this flag has been turned on. Also, the early checking of "iommu_enabled" in iommu_setup() is removed to prevent iommu functionalities from been disabled on amd systems.
