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.
