Web• Collaborative Processor Performance Control (CPPC) extension: support platform-based, fully autonomous selection of performance states with OSPM providing information that guides the selection. Additionally, the UEFI Forum is now responsible for assigning the Plug-and-Play (PNP) Identifiers and the ACPI Identifiers to avoid namespace collision. CPPC exposes a set of registers to describe abstract performance scale, to request performance levels and to measure per-cpu delivered performance. For more details on CPPC please refer to the ACPI specification at: http://uefi.org/specifications Some of the CPPC registers are exposed via sysfs under: /sys/devices/system/cpu/cpuX/acpi_cppc/
