From 70e89132c9e67473b7cbb507dd13c96aab598517 Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Fri, 14 Feb 2020 14:27:44 +0100 Subject: hw/arm/virt: Add the virtio-iommu device tree mappings Adds the "virtio,pci-iommu" node in the host bridge node and the RID mapping, excluding the IOMMU RID. This is done in the virtio-iommu-pci hotplug handler which gets called only if no firmware is loaded or if -no-acpi is passed on the command line. As non DT integration is not yet supported by the kernel we must make sure we are in DT mode. This limitation will be removed as soon as the topology description feature gets supported.
