With the VIOT support in place, x86 platforms can now use the virtio-iommu. Because the other x86 IOMMU drivers aren't yet ready to use the acpi_dma_setup() path, x86 doesn't implement arch_setup_dma_ops() at the moment. Similarly to Vt-d and AMD IOMMU, clear the DMA ops and call iommu_setup_dma_ops() from probe_finalize(). Acked-by: Joerg Roedel <jroedel@suse.de> Acked-by: Michael S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
