 810  * The amdgpu driver provides a sysfs API for adjusting what power levels
 811  * are enabled for a given power state.  The files pp_dpm_sclk, pp_dpm_mclk,
 812  * pp_dpm_socclk, pp_dpm_fclk, pp_dpm_dcefclk and pp_dpm_pcie are used for
 813  * this.
 814  *
 815  * pp_dpm_socclk and pp_dpm_dcefclk interfaces are only available for
 816  * Vega10 and later ASICs.
 817  * pp_dpm_fclk interface is only available for Vega20 and later ASICs.
 818  *
 819  * Reading back the files will show you the available power levels within
 820  * the power state and the clock information for those levels.
 821  *
 822  * To manually adjust these states, first select manual using
 823  * power_dpm_force_performance_level.
 824  * Secondly, enter a new value for each level by inputing a string that
 825  * contains " echo xx xx xx > pp_dpm_sclk/mclk/pcie"
 826  * E.g.,

 828  * .. code-block:: bash
 829  *
 830  *      echo "4 5 6" > pp_dpm_sclk
 831  *
 832  * will enable sclk levels 4, 5, and 6.
