Some platforms supports multiple low power states for CPUs that can be used when entering system-wide suspend. Currently we are always selecting the deepest possible state for the CPUs, which can break the system wakeup latency constraint that may be required for a use case. Let's take the first step towards addressing this problem, by introducing an interface for user space, that allows us to specify the CPU system wakeup QoS limit. Subsequent changes will start taking into account the new QoS limit.

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.
