With this configuration opened, the basic platform-independent s2idle is provided by the sole "s2idle" string in `/sys/power/mem_sleep`. At the end of s2idle, harts will hit the `wfi` instruction or enter the SUSPENDED state through the sbi_cpuidle driver. The interrupt of possible wakeup devices will be kept to wake the system up. And platform-specific sleep states can be provided by future ACPI and SBI SUSP extension support.

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.
