Hi @Deucher, Alexander<mailto:Alexander.Deucher at amd.com> & @Zhu, Rex<mailto:Rex.Zhu at amd.com>, I can remove the od setings for power limit and fan speed related since they seem redundant with other sysfs apis. But for the clock/voltage related, i can not see how to reuse old pp_od_clk_voltage APIs. For the old pp_od_clk_voltage APIs, 1. they output/input the voltages in their exact values. E.g. "s 1 500 820" will update sclk level 1 to be 500 MHz at 820 mV But for vega20, we did not know its original voltage value. The output/input for voltage are just offest from its original value. So, if to reuse these APIs, we will make them have two different explanations( on vega20 or later, the voltage is offset. On previous ASICs, the voltage is exact value). I think that will confuse the users. 2. they support voltage set for each level. But for vega20, it supports only three pairs of clock/voltage set. And per suggestion, these three pairs should be: voltage offset of minimum clock level, voltage offset for middle clock level and voltage offset for maximum clock level. Also, i believe the future ASICs will also take the vega20 OD ways(that is we need the offset, not the exact value for voltage). So, based on previous considerations, i decide to have new APIs instead of reusing existing ones.

Those new added interfaces for OD parameters get/set seems have no difference with the old interface. int (*print_clock_levels)(struct pp_hwmgr *hwmgr, enum pp_clock_type type, char *buf); int (*odn_edit_dpm_table)(struct pp_hwmgr *hwmgr, enum PP_OD_DPM_TABLE_COMMAND type, long *input, uint32_t size);
