Sunil V L <sunilvl@ventanamicro.com> says: This series enables the support for "Collaborative Processor Performance Control (CPPC) on ACPI based RISC-V platforms. It depends on the encoding of CPPC registers as defined in RISC-V FFH spec [2]. CPPC is described in the ACPI spec [1]. RISC-V FFH spec required to enable this, is available at [2].

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.
