When the SUSP SBI extension is present it implies that the standard "suspend to RAM" type is available. Wire it up to the generic platform suspend support, also applying the already present support for non-retentive CPU suspend. When the kernel is built with CONFIG_SUSPEND, one can do 'echo mem > /sys/power/state' to suspend. Resumption will occur when a platform-specific wake-up event arrives.

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.
