A Primer to Clocks and Power Management Through ARM SCMI

Explore the fundamentals of ARM System Control and Management Interface (SCMI) in this 26-minute conference talk. Delve into the standardized communication protocol for managing power, performance, and system resources in multi-core systems. Learn how platform controllers can be integrated into Trusted Firmware-A (TF-A) for power and clock management. Discover the process of implementing SCMI protocol and associated Linux kernel drivers for new devices to communicate with secure entities like TF-A. Gain insights into the benefits of using ARM SCMI for efficient development on heterogeneous systems. Examine the current state of kernel and TF-A SCMI clock and power domain drivers, and identify areas for potential improvements and optimizations.
