Quote: pp_od_clk_voltage
The amdgpu driver provides a sysfs API for adjusting the clocks and voltages in each power level within a power state. The pp_od_clk_voltage is used for this.
< For Vega10 and previous ASICs >
Reading the file will display:
a list of engine clock levels and voltages labeled OD_SCLK a list of memory clock levels and voltages labeled OD_MCLK a list of valid ranges for sclk, mclk, and voltage labeled OD_RANGE
To manually adjust these settings, first select manual using power_dpm_force_performance_level. ...
