Description

Platform drivers are the implementation of the different profiles for the whole system. A driver will need to implement support for power-saver and balanced at a minimum.

If no system-specific platform driver is available, a placeholder driver will be put in place, and the performance profile will be unavailable.

There should not be a need to implement system-specific drivers, as the [platform_profile] (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/ABI/testing/sysfs-platform_profile) kernel API offers a way to implement system-specific profiles which power-profiles-daemon can consume.

When a driver implements the performance profile, it might set the “performance-degraded” property if the profile isn't running to its fullest performance for any reason, such as thermal limits being reached, or because a part of the user's body is too close for safety, for example.
