[PATCH v7 3/3] PM: Introduce Intel PowerClamp Driver

2013-01-16 Thread Jacob Pan
Intel PowerClamp driver performs synchronized idle injection across all online CPUs. The goal is to maintain a given package level C-state ratio. Compared to other throttling methods already exist in the kernel, such as ACPI PAD (taking CPUs offline) and clock modulation, this is often more effici
