Processor AUX Power Management
VCCIN AUX IMON Feature
This feature is the new power feature which allows the processor to read VCCIN Aux average current via the IMVP9.1 controller over SVID.
It allows the processor to get an accurate power estimation of VCCIN Aux, which is reflected in more accurate package power reporting and better accuracy in meeting the package power limits (PL1, PL2, and PL3).
