A number of the command line controlled variables are x86- or even x86-HVM-specific. Don't have those variables elsewhere in the first place (in some cases replace them by a #define), and as a result also don't silently accept such "iommu=" sub-options which in fact have no effect.
I can confirm that all the parameters listed below are not used on Arm.
1: iommu_intremap is x86-only 2: iommu_intpost is x86/HVM-only 3: iommu_igfx is x86-only 4: iommu_qinval is x86-only 5: iommu_snoop is x86/HVM-only The series contextually depends on "AMD/IOMMU: without XT, x2APIC needs to be forced into physical mode" Jan
