Linux kernel source tree
1c14b0e4ba
Lacking the support of device specific mapping supported in virtio, VDUSE must trick the DMA API in order to make virtio-vdpa transport work. This is done by advertising vDPA device as dma device with a VDUSE specific dma_ops even if it doesn't do DMA at all. This will be fixed by this patch. Thanks to the new mapping operations support by virtio and vDPA. VDUSE can simply switch to advertise its specific mappings operations to virtio via virtio-vdpa then DMA API is not needed for VDUSE any more and iova domain could be used as the mapping token instead.

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 reStructuredText 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.
