Insert "iommus" property pointed to the IOMMU node with "xen,grant-dma" compatible to all virtio devices which backends are going to run in non-hardware domains (which are non-trusted by default). Based on device-tree binding from Linux: Documentation/devicetree/bindings/iommu/xen,grant-dma.yaml The example of generated nodes: xen_iommu { compatible = "xen,grant-dma"; #iommu-cells = <0x01>; phandle = <0xfde9>; }; virtio@2000000 { compatible = "virtio,mmio"; reg = <0x00 0x2000000 0x00 0x200>; interrupts = <0x00 0x01 0xf01>; interrupt-parent = <0xfde8>; dma-coherent; iommus = <0xfde9 0x01>; }; virtio@2000200 { compatible = "virtio,mmio"; reg = <0x00 0x2000200 0x00 0x200>; interrupts = <0x00 0x02 0xf01>; interrupt-parent = <0xfde8>; dma-coherent; iommus = <0xfde9 0x01>; }; Signed-off-by: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx> Reviewed-by: Stefano Stabellini <sstabellini@xxxxxxxxxx> Reviewed-by: Anthony PERARD <anthony.perard@xxxxxxxxxx> commit 2128143c114c52c7536e37c32935fdd77f23edc1 Author: Julien Grall <julien.grall@xxxxxxx> Date: Fri Jul 15 22:20:25 2022 +0300 libxl: Introduce basic virtio-mmio support on Arm This patch introduces helpers to allocate Virtio MMIO params (IRQ and memory region) and create specific device node in the Guest device-tree with allocated params. In order to deal with multiple Virtio devices, reserve corresponding ranges. For now, we reserve 1MB for memory regions and 10 SPIs. As these helpers should be used for every Virtio device attached to the Guest, call them for Virtio disk(s). Please note, with statically allocated Virtio IRQs there is a risk of a clash with a physical IRQs of passthrough devices. For the first version, it's fine, but we should consider allocating the Virtio IRQs automatically. Thankfully, we know in advance which IRQs will be used for passthrough to be able to choose non-clashed ones.

Although the Virtio block device is quite different from traditional Xen PV block device (vbd) from the toolstack's point of view: - as the frontend is virtio-blk which is not a Xenbus driver, nothing written to Xenstore are fetched by the frontend currently ("vdev" is not passed to the frontend). But this might need to be revised in future, so frontend data might be written to Xenstore in order to support hotplugging virtio devices or passing the backend domain id on arch where the device-tree is not available. - the ring-ref/event-channel are not used for the backend<->frontend communication, the proposed IPC for Virtio is IOREQ/DM it is still a "block device" and ought to be integrated in existing "disk" handling. So, re-use (and adapt) "disk" parsing/configuration logic to deal with Virtio devices as well. For the immediate purpose and an ability to extend that support for other use-cases in future (Qemu, virtio-pci, etc) perform the following actions: - Add new disk backend type (LIBXL_DISK_BACKEND_STANDALONE) and reflect that in the configuration - Introduce new disk "specification" and "transport" fields to struct libxl_device_disk. Both are written to the Xenstore. The transport field is only used for the specification "virtio" and it assumes only "mmio" value for now. - Introduce new "specification" option with "xen" communication protocol being default value. - Add new device kind (LIBXL__DEVICE_KIND_VIRTIO_DISK) as current one (LIBXL__DEVICE_KIND_VBD) doesn't fit into Virtio disk model An example of domain configuration for Virtio disk: disk = [ 'phy:/dev/mmcblk0p3, xvda1, backendtype=standalone, specification=virtio'] Nothing has changed for default Xen disk configuration. Please note, this patch is not enough for virtio-disk to work on Xen (Arm), as for every Virtio device (including disk) we need to allocate Virtio MMIO params (IRQ and memory region) and pass them to the backend, also update Guest device-tree. The subsequent patch will add these missing bits. For the current patch, the default "irq" and "base" are just written to the Xenstore. This is not an ideal splitting, but this way we avoid breaking the bisectability.
