The region provisioning flow involves selecting interleave ways + granularity settings for a region, and then programming the decoder topology to meet those constraints, if possible. For example, root decoders set the minimum interleave ways + granularity for any hosted regions. Given decoder programming is not atomic and collisions can occur between multiple requesting regions userspace will be responsible for conflict resolution and it needs these attributes to make those decisions.

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.
