Frequency-invariant accounting support based on the ratio of current frequency and maximum supported frequency is an optional feature an arch can implement. Since there are cpufreq drivers (e.g. cpufreq-dt) which can be build for different arch's a default implementation of the frequency-invariance setter function arch_set_freq_scale() is needed. This default implementation is an empty weak function which will be overwritten by a strong function in case the arch provides one. The setter function passes the cpumask of related (to the frequency change) cpus (online and offline cpus), the (new) current frequency and the maximum supported frequency.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
