Now that amd-iommu support interrupt remapping, enable the GASup in IVRS table and GASup in extended feature register to indicate that IOMMU support guest virtual APIC mode. GASup provides option to guest OS to make use of 128-bit IRTE. Note that the GAMSup is set to zero to indicate that amd-iommu does not support guest virtual APIC mode (aka AVIC) which would be used for the nested VMs. See Table 21 from IOMMU spec for interrupt virtualization controls Signed-off-by: Brijesh Singh <brijesh.singh@amd.com> Reviewed-by: Peter Xu <peterx@redhat.com> Cc: Peter Xu <peterx@redhat.com> Cc: "Michael S.
