I am testing this on ARM64 and see below continuous error prints:
virtio_iommu_translate sid=8 is not known!!
virtio_iommu_translate sid=8 is not known!!
virtio_iommu_translate sid=8 is not known!!
virtio_iommu_translate sid=8 is not known!!
virtio_iommu_translate sid=8 is not known!!
virtio_iommu_translate sid=8 is not known!!
virtio_iommu_translate sid=8 is not known!!
virtio_iommu_translate sid=8 is not known!!
virtio_iommu_translate sid=8 is not known!!
virtio_iommu_translate sid=8 is not known!!
Also in guest I do not see device-tree node with virtio-iommu.
I am using qemu-tree you mentioned below and iommu-driver patches published by
Jean-P.
Qemu command line have additional ""-device virtio-iommu-device". What I am
missing ?
Thanks
