ARMv9/v8 Power Management Domains (Voltage Domain/Power Domain)

ARMv9/v8 Power Management Domains (Voltage Domain/Power Domain)

ver0.2 Introduction In previous articles, we briefly introduced the Power Control Framework (PCF) and understood the main functions of its core components, which revolve around two key concepts: “power domains” and “power modes”. Building on this foundation, this article will further explore the concept of granular “domains” controlled by the SCP for various agents. Modern … Read more
