The System Control and Management Interface (SCMI) is a set of operating system-independent software interfaces that are used in system resources management that has been originally specified to standardize the interface between Application Processors and the power coprocessor. Nevertheless, systems dont always have a dedicated coprocessor for system resources management but still need to safely manage them.The secure world is a good candidate as it uses some of these critical resources. Instead of defining a new custom interface, it has been decided to enable a SCMI server in secure world that will handle system request from all agents of the system being the non secure world of AP or other processors of the system.<br /> This talk will present the SCMI server implementation in secure world, the constraints that have driven the implementation choices, the open items and next features. During the talk, we will have a special focus on the OP-TEE arm32 implementation.
