    sys/kern             kern_cpu.c 
  Log:
  Add support for the CPUFREQ_FLAG_INFO_ONLY flag.  Devices that report this
  are not added to the list(s) of available settings.  However, other drivers
  can call the CPUFREQ_DRV_SETTINGS() method on those devices directly to
  get info about available settings.
  
  Update the acpi_perf(4) driver to use this flag in the presence of
  "functional fixed hardware."  Thus, future drivers like Powernow can
  query acpi_perf for platform info but perform frequency transitions
  themselves.
