This driver offers two or more settings as exported via the ACPI _PSS method. OEMs use this interface to encapsulate chipset or processor-specific methods (e.g., SpeedStep or Powernow) and export their settings in a standard way. On systems that have valid ACPI Performance states and a hardware-specific driver (e.g., ichss), acpi_perf(4) is preferred. END
