Intelligent Power Allocation (IPA) Intelligent Power Allocation (IPA) is a thermal governor that uses a PID (Proportional Integral Derivative) controller to control temperature. Based on the delta from the target temperature, the governor estimates the available power budget. This budget is intelligently allocated among the active actors (CPU cluster, GPUs, etc.) in the system to maximize performance while maintaining temperature control. The governor relies on actor power models which translate performance into power consumption and vice versa. -This kernel contains the set of patches that introduce the power allocator governor, the power actor interface along with an implementation of a simple power model for the CPU cluster actors. The governor and the actor interfaces are used to create a platform thermal management solution for ARM Juno 64-bit Development Platform. +This kernel contains the set of patches that introduce the power allocator governor, the power actor interface along with an implementation of a simple power model for the CPU cluster actors.
