Documentation: Add documentation about class interface for platform profiles2024-12-10T17:18:22ZMario Limonciellomario.limonciello@amd.com2024-12-06T03:19:18Zurn:sha1:0056b0852c326cf21201661f68ab41002ae9a845
The class interface allows changing multiple platform profiles on a system
to different values. The semantics of it are similar to the legacy
interface.

Documentation: Add documentation for new platform_profile sysfs attribute2020-12-30T17:28:57ZMark Pearsonmarkpearson@lenovo.com2020-12-30T00:18:25Zurn:sha1:8e0cbf356377fabac47a027dd176cd1cacc5fc01
On modern systems the platform performance, temperature, fan and other
hardware related characteristics are often dynamically configurable. The
profile is often automatically adjusted to the load by some
automatic-mechanism (which may very well live outside the kernel).
These auto platform-adjustment mechanisms often can be configured with
one of several 'platform-profiles', with either a bias towards low-power
consumption or towards performance (and higher power consumption and
thermals).
Introduce a new platform_profile sysfs API which offers a generic API for
selecting the performance-profile of these automatic-mechanisms.
