KVM: arm64: vgic-its: Implement vgic_mmio_uaccess_write_its_iidr The GITS_IIDR revision field is used to encode the migration ABI revision. So we need to restore it to check the table layout is readable by the destination. By writing the IIDR, userspace thus forces the ABI revision to be used and this must be less than or equal to the max revision KVM supports.
