Recall that the Device Physical Address (DPA) space of a CXL Memory Expander is potentially partitioned into a volatile and persistent portion. A decoder maps a Host Physical Address (HPA) range to a DPA range and that translation depends on the value of all previous (lower instance number) decoders before the current one. In preparation for allowing dynamic provisioning of regions, decoders need an ABI to indicate which DPA partition a decoder targets. This ABI needs to be prepared for the possibility that some other agent committed and locked a decoder that spans the partition boundary. Add 'decoderX.Y/mode' to endpoint decoders that indicates which partition 'ram' / 'pmem' the decoder targets, or 'mixed' if the decoder currently spans the partition boundary.

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.
