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.

The Linux kernel user-space API guide
|
|
=====================================
|
|
|
|
.. _man-pages: https://www.kernel.org/doc/man-pages/
|
|
|
|
While much of the kernel's user-space API is documented elsewhere
|
|
(particularly in the man-pages_ project), some user-space information can
|
|
also be found in the kernel tree itself. This manual is intended to be the
|
|
place where this information is gathered.
