schedutil is already a hard-requirement for EAS, which has lead to making it default on arm (when CONFIG_BIG_LITTLE), see: commit8fdcca8e25("cpufreq: Select schedutil when using big.LITTLE") One thing worth pointing out is that schedutil isn't only relevant for asymmetric CPU capacity systems; for instance, schedutil is the only governor that honours util-clamp performance requests. Another good example of this is x86 switching to using it by default in: commita00ec3874e("cpufreq: intel_pstate: Select schedutil as the default governor") Arguably it should be made the default for all architectures, but it seems better to wait for them to also gain frequency invariance powers. Make it the default for arm && arm64 for now.

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.
