ARM System Control and Management Interface (SCMI) protocol is a
|
||
|
|
set of operating system-independent software interfaces that are
|
||
|
|
used in system management. SCMI is extensible and currently provides
|
||
|
|
interfaces for: Discovery and self-description of the interfaces
|
||
|
|
it supports, Power domain management which is the ability to place
|
||
|
|
a given device or domain into the various power-saving states that
|
||
|
|
it supports, Performance management which is the ability to control
|
||
|
|
the performance of a domain that is composed of compute engines
|
||
|
|
such as application processors and other accelerators, Clock
|
||
|
|
management which is the ability to set and inquire rates on platform
|
||
|
|
managed clocks and Sensor management which is the ability to read
|
||
|
|
sensor data, and be notified of sensor value.
|
||
|
|
|
||
|
|
This protocol library provides interface for all the client drivers
|
||
|
|
making use of the features offered by the SCMI.
