By design, SCMI performance domains define the granularity of performance controls, they do not describe any underlying hardware dependencies (although they may match in many cases). It is therefore possible to have some platforms where hardware may have the ability to control CPU performance at different granularity and choose to describe fine-grained performance control through SCMI. In such situations, the energy model would be provided with inaccurate information based on controls, while it still needs to know the performance boundaries. To restore correct functionality, retrieve information of CPUs under the same performance domain from operating-points-v2 in DT, and pass it on to EM.

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.
