Qualcomm Snapdragon SoCs feature a rich and complex power management architecture, which maximizes frequency and power control of each sub-component. Nearly nothing is connected directly to fixed clock or power sources. This can achieve outstanding performance/power ratios, but also brings some software implementation challenges. In this talk, Konrad will describe how Qualcomm’s power management model affects the upstream kernel today. He will highlight some of the biggest outstanding issues, and outline the end-user experience impact. He will also present ways to rectify these problems that could improve power savings while retaining system snappiness.
