 816  * pp_dpm_socclk and pp_dpm_dcefclk interfaces are only available for
 817  * Vega10 and later ASICs.
 818  * pp_dpm_fclk interface is only available for Vega20 and later ASICs.

 820  * Reading back the files will show you the available power levels within
 821  * the power state and the clock information for those levels.
 822  *
 823  * To manually adjust these states, first select manual using
 824  * power_dpm_force_performance_level.
