SAGV Points

SAGV (System Agent Geyserville) is a way by which the SoC can dynamically scale the work point (V/F), by applying DVFS (Dynamic Voltage Frequency Scaling) based on memory bandwidth utilization and/or the latency requirement of the various workloads for better energy efficiency at System-Agent. Pcode heuristics are in charge of providing request for Qclock work points by periodically evaluating the utilization of the memory and IA stalls.

Notes:
  1. The processors supports dynamic gearing technology where the Memory Controller can run at 1:1 (Gear-1, Legacy mode) or 1:2 (Gear-2 mode) and 1:4 (Gear-4 mode) ratio of DRAM speed. The gear ratio is the ratio of DRAM speed to Memory Controller Clock. MC Channel Width equal to DDR Channel width multiply by Gear Ratio
  2. SA-GV modes
    1. LowBW - Low frequency point, Minimum Power point. Characterized by low power, low BW, high latency. The system will stay at this point during low to moderate BW consumption.
    2. MedBW - Tuned for balance between power and performance
    3. HighBW - Characterized by high power, low latency, moderate BW also used as RFI mitigation point.
    4. MaxBW/Lowest Latency - Lowest Latency point, low BW and highest power.
