From: Eric Auger <eric.auger(a)redhat.com&gt; redhat/configs: Fix CONFIG_VIRTIO_IOMMU to 'y' on aarch64 Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1972795 Upstream Status: RHEL only Tested: on ARM with qemu (Jean-Philippe Brucker's qemu branch as the qemu integration is not yet upstream, with both protected virtio-blk-pci and a virtio-net-pci devices) Commit fe6d9534dbe4 ("redhat/configs: Set CONFIG_VIRTIO_IOMMU on aarch64") enabled the compilation of the virtio-iommu driver on ARM but set the config to 'm'. However if there are devices behind the vIOMMU that are needed during the boot such as a virtio-blk-pci device, the guest fails to boot as the driver is not loaded. Let's fix this bootstrap issue by compiling the driver in-kernel as it is done for other iommu drivers.
