    sys/dev/acpica       acpi_perf.c 
  Log:
  Add the ACPI Performance states driver.  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.
