           Summary: PowerTOP should use the supported_max_cstates kstat
                    field
    Classification: Development
           Product: power-mgmt
           Version: unspecified
          Platform: Other
        OS/Version: OpenSolaris
            Status: ACCEPTED
          Severity: minor
          Priority: P3
         Component: powertop

PowerTOP currently enumerates idle states as the system transitions between
them, in other words, the tool doesn't know how that a state is supported until
the system transitions to it. With the integration of PAD, we now know how many
c-states are supported on a system. The kstat cpu_info module has the
supported_max_cstates field for this purpose.
