The old transfer ioctls may work on blob resources, and there is no TRANSFER_BLOB hypercall now for simplicity. The guest may have a image view on the blob resources such that the stride is not equal to width * bytes_per_pixel. For host-only blobs, we can repurpose the transfer ioctls to synchronize caches as well. For guest-only blobs, these operations are undefined for now so leave them out. Also, with seamless Wayland integration between guest/host looking increasingly attractive, it also makes sense to keep track of one value for stride.

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.
