If the PSCI OSI mode isn't supported or fails to be enabled, the PM domain topology with the genpd providers isn't initialized. This is perfectly fine from cpuidle-psci point of view. However, since the PM domain topology in the DTS files is a description of the HW, no matter of whether the PSCI OSI mode is supported or not, other consumers besides the CPUs may rely on it. Therefore, let's always allow the initialization of the PM domain topology to succeed, independently of whether the PSCI OSI mode is supported. Consequentially we need to track if we succeed to enable the OSI mode, as to know when a domain idlestate can be selected. Note that, CPU devices are still not being attached to the PM domain topology, unless the PSCI OSI mode is supported.

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.
