Better Thermal Management for the Workstation
Summary
Better thermal management and peak performance on Intel CPUs by including thermald in the default install.

- Product: Workstation
- Responsible WG: Workstation

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.
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.
