The Energy Aware Scheduler (EAS) used to rely on statically defined Energy Models (EMs) in the device tree. Now that EAS uses the EM framework, the old-style EMs are not usable by default. To address this issue, introduce a driver able to read DT-based EMs and to load them in the EM framework, hence making them available to EAS. Since EAS now uses only the active costs of CPUs, the idle cost and cluster cost of the old EM are ignored. The driver can be compiled in using the CONFIG_LEGACY_ENERGY_MODEL_DT Kconfig option (off by default). The implementation of the driver is highly inspired by the EM loading code from android-4.14 and before (written by Robin Randhawa <robin.randhawa@arm.com>), and the arch_topology driver (Juri Lelli <juri.lelli@redhat.com>).

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.
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.
