Arm SCMI spec. v3.2, s4.5.3.4 PERFORMANCE_DOMAIN_ATTRIBUTES defines a per-domain rate_limit for performance requests: """ Rate Limit in microseconds, indicating the minimum time required between successive requests. A value of 0 indicates that this field is not supported by the platform. This field does not apply to FastChannels. """" The field is first defined in SCMI v1.0. Add support to fetch this value and advertise it through a rate_limit_get() callback.

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.
