Learn how to abstract peripheral resources using performance and power domains in this 31-minute technical talk from Linaro. Explore an innovative approach that extends beyond traditional CPU-focused performance domains to encompass non-CPU devices like clocks, regulators, interconnects, and PHYs. Discover the implementation of logical performance and power domains for peripheral devices, eliminating the need to manage individual components separately. Examine how firmware resource abstraction and SCMI power and performance protocols optimize peripheral resource configuration and requests, leading to reduced agent-platform traffic and improved boot Key Performance Indicators (KPIs). Follow along with the latest upstreaming efforts and implementation strategies for this resource management technique.
