Linux kernel source tree
ce0e3c403e
Add struct iova_allocator, which gives tests a convenient way to generate legally-accessible IOVAs to map. This allocator traverses the sorted available IOVA ranges linearly, requires power-of-two size allocations, and does not support freeing iova allocations. The assumption is that tests are not IOVA space-bounded, and will not need to recycle IOVAs. This is based on Alex Williamson's patch series for adding an IOVA allocator [1].

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.
