commit c47e5d94d0bd0c283bf7f1b31e42314065d82be4 Author: Xenia Ragiadakou <burzalodowa@xxxxxxxxx> AuthorDate: Thu Jan 12 11:09:16 2023 +0100 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Thu Jan 12 11:09:16 2023 +0100 x86/iommu: introduce AMD-Vi and Intel VT-d Kconfig options Introduce two new Kconfig options, AMD_IOMMU and INTEL_IOMMU, to allow code specific to each IOMMU technology to be separated and, when not required, stripped. AMD_IOMMU will be used to enable IOMMU support for platforms that implement the AMD I/O Virtualization Technology. INTEL_IOMMU will be used to enable IOMMU support for platforms that implement the Intel Virtualization Technology for Directed I/O. Since, at this point, disabling any of them would cause Xen to not compile, the options are not visible to the user and are enabled by default if X86.
