arch_topology.c provides functionality to parse and scale CPU capacity. It also provides a corresponding sysfs interface. Some architectures parse and scale CPU capacity differently as per their own needs. On Intel processors, for instance, it is responsibility of the Intel P-state driver. Relocate the implementation of that interface to a common location in topology.c. Architectures can use the interface and populate it using their own mechanisms. An alternative approach would be to compile arch_topology.c even if not needed only to get this interface. This approach would create duplicated and conflicting functionality and data structures.

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 reStructuredText 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.
