Create the /sys/bus/cxl hierarchy to enumerate: * Memory Devices (per-endpoint control devices) * Memory Address Space Devices (platform address ranges with interleaving, performance, and persistence attributes) * Memory Regions (active provisioned memory from an address space device that is in use as System RAM or delegated to libnvdimm as Persistent Memory regions). For now, only the per-endpoint control devices are registered on the 'cxl' bus. However, going forward it will provide a mechanism to coordinate cross-device interleave.

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.
