I've been quite intrigued by the recent advancements in power management technology, particularly regarding AMD's Advanced Power Management firmware. As I delved into the subject, I began to wonder about the specific ways in which this firmware manages and conserves power within AMD's processors.
Additionally, I found the role of the System Management Unit (SMU) in achieving fine-grained power gating at the sub-core level to be particularly fascinating. It seems that the SMU plays a crucial part in optimizing power efficiency, but I would love to understand more about this process.
Could someone provide me with some detailed insights into how AMD's Advanced Power Management firmware functions to save power in these processors, and how the SMU contributes to this clock gating and power gating mechanism?
