For regular cpuidle states we are reflecting over the selected/entered state to see if the sleep-duration meets the residency for the state. The output from the reflection is an "above" value to indicate the number of times the state was too deep and a "below" value for the number of times it was too shallow. Let's implement the similar thing for genpd's domain-idlestates along with genpd's governor and put the information in the genpd's debugfs.

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 reStructuredText 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.
