== Summary ==
Better thermal management and peak performance on Intel CPUs by
including thermald in the default install.

== Detailed Description ==
Modern Intel-based systems provide sensors and methods to monitor and
control temperature of its CPUs. The Thermal daemon will use those
sensors to monitor the temperature and use the best available method
to keep the CPU in the right temperature envelop. On certain systems
this is needed to reach the maximal performance. For optimal
performance a per-model thermald configuration should be created, this
can either be done by using dptfxtract (available from rpmfusion) or
we could ship static configuration files for a set of known models.
So what are we going to do about this in F32? Are we going to create
configuration files or we will provide some page how to create it
yourself? Does Intel provide one?
For a more details explanation please consult Intel's
introduction] to thermald.
== Benefit to Fedora ==
Better out-of-the-box experience due to improved cooling methods and
performance on Intel systems.
== Scope ==
* Proposal owners:
- Include the thermald package in the default Workstation install
- Optionally provide patches for thermald to be able to read hardware
specific configuration data
- Optionally collect hardware specific configuration data and ship it
* Other developers: N/A (not a System Wide Change)
* Release engineering:
* Policies and guidelines: N/A (not a System Wide Change)
* Trademark approval: N/A (not needed for this Change)
== Upgrade/compatibility impact ==
N/A (not a System Wide Change)
== How To Test ==
Install the packages and use e.g. turbostat to monitor the
performance. Improvements may only be visible if the non-free
dptfxtract package is also installed.
So what is the point of a change if improvements are visible only if
non-free package is installed?
