Once the QTG ID _DSM is executed successfully, the QTG ID is retrieved from the return package. Create a list of entries in the cxl_memdev context and store the QTG ID as qos_class token and the associated DPA range. This information can be exposed to user space via sysfs in order to help region setup for hot-plugged CXL memory devices.

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.
