From 8b4eb09e32456ebd769fe09a1aa338d6a3536376 Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Fri, 14 Feb 2020 14:27:43 +0100 Subject: virtio-iommu-pci: Add virtio iommu pci support This patch adds virtio-iommu-pci, which is the pci proxy for the virtio-iommu device. Currently non DT integration is not yet supported by the kernel. So the machine must implement a hotplug handler for the virtio-iommu-pci device that creates the device tree iommu-map bindings as documented in kernel documentation: Documentation/devicetree/bindings/virtio/iommu.txt Signed-off-by: Eric Auger Reviewed-by: Jean-Philippe Brucker Reviewed-by: Michael S.
