    282  * are enabled for each clock domain via the sysfs pp_dpm_mclk, pp_dpm_sclk,

    293  * mode is recommended for profiling specific work loads where you do
    294  * not want clock or power gating for clock fluctuation to interfere
    295  * with your results. profile_standard sets the clocks to a fixed clock
    296  * level which varies from asic to asic.  profile_min_sclk forces the sclk
    297  * to the lowest level.  profile_min_mclk forces the mclk to the lowest level.

    676  *
    677  * - a list of valid ranges for sclk, mclk, and voltage labeled OD_RANGE
    678  *
    679  * To manually adjust these settings, first select manual using
    680  * power_dpm_force_performance_level. Enter a new value for each
    681  * level by writing a string that contains "s/m level clock voltage" to
    682  * the file.  E.g., "s 1 500 820" will update sclk level 1 to be 500 MHz
    683  * at 820 mV; "m 0 350 810" will update mclk level 0 to be 350 MHz at
    684  * 810 mV.  When you have edited all of the states as needed, write
    685  * "c" (commit) to the file to commit your changes.  If you want to reset to the
    686  * default power levels, write "r" (reset) to the file to reset them.

    709  *   should be 0 if to set minimum clock. And 1 if to set maximum
    710  *   clock. E.g., "s 0 500" will update minimum sclk to be 500 MHz.
    711  *   "m 1 800" will update maximum mclk to be 800Mhz.
    712  *
    713  *   For sclk voltage curve, enter the new values by writing a
    714  *   string that contains "vc point clock voltage" to the file. The
    715  *   points are indexed by 0, 1 and 2. E.g., "vc 0 300 600" will
    716  *   update point1 with clock set as 300Mhz and voltage as
    717  *   600mV. "vc 2 1000 1000" will update point3 with clock set

    953  *
    954  * The amdgpu driver provides a sysfs API for adjusting what power levels
    955  * are enabled for a given power state.  The files pp_dpm_sclk, pp_dpm_mclk,
    956  * pp_dpm_socclk, pp_dpm_fclk, pp_dpm_dcefclk and pp_dpm_pcie are used for
    957  * this.
    958  *
    959  * pp_dpm_socclk and pp_dpm_dcefclk interfaces are only available for
    960  * Vega10 and later ASICs.
    961  * pp_dpm_fclk interface is only available for Vega20 and later ASICs.
    962  *
    963  * Reading back the files will show you the available power levels within
    964  * the power state and the clock information for those levels.
    965  *
    966  * To manually adjust these states, first select manual using
    967  * power_dpm_force_performance_level.
    968  * Secondly, enter a new value for each level by inputing a string that
    969  * contains " echo xx xx xx > pp_dpm_sclk/mclk/pcie"
    970  * E.g.,
    971  *
    972  * .. code-block:: bash
    973  *
    974  *	echo "4 5 6" > pp_dpm_sclk
    975  *
    976  * will enable sclk levels 4, 5, and 6.
    977  *
    978  * NOTE: change to the dcefclk max dpm level is not supported now
