The ctrl_val[] array for a struct rdt_hw_resource only holds configurations of one type. The type is implicit. Once the CDP resources are merged, the ctrl_val[] array will hold all the configurations for the hardware resource. When a particular type of configuration is needed, it must be specified explicitly. Pass the expected type from the schema into resctrl_arch_get_config(). Nothing uses this yet, but once a single ctrl_val[] array is used for the three struct rdt_hw_resources that share hardware, the type will be used to return the correct configuration value from the shared array.

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.
