System Control and Management Interface (SCMI) is a communication
|
|
protocol that defines standard interfaces for power, performance
|
|
and system management. The SCMI specification is available at
|
|
https://developer.arm.com/architectures/system-architectures/software-standards/scmi
|
|
|
|
An SCMI agent communicates with a related SCMI server firmware
|
|
located in another sub-system, as a companion micro controller
|
|
or a companion host in the CPU system.
|
|
|
|
Communications between agent (client) and the SCMI server are
|
|
based on message exchange. Messages can be exchange over tranport
|
|
channels as a mailbox device or an Arm SMCCC service with some
|
|
piece of identified shared memory.
