            Bug ID: 110208
           Summary: New GPU sysfs Power State Interface for custom
                    pp_od_clk_voltage
           Product: DRI
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: richard.llom@gmail.com

In order to use a custom pp_od_clk_voltage one has to set
power_dpm_force_performance_level to manual.

However this way it is not possible to use custom pp_od_clk_voltage and force -
for instance - high or peak performance levels.

The forcing of different performance levels doesn't (and shouldn't) relate to
custom clocks/voltages. Putting this setting in the same interface is a poor
choice and (unnecessarily) restricts the possibilities.

Please add a new sysfs interface for *solely* choosing between default and
custom pp_od_clk_voltage.
