      drm/amd/pm: improve the fine grain tuning function for RV/RV2/PCO · 37030aba
      Xiaojian Du authored
      This patch is to improve the fine grain tuning function for RV/RV2/PCO.
      This patch adds two new commands: "restore" and "commit".
      This function uses the pp_od_clk_voltage sysfs file to configure the min
      and max value of gfx clock frequency manually or restore the default value.
      
      Command guide:
      echo "s level value" > pp_od_clk_voltage
              "s" - set the sclk frequency
              "level" - 0 or 1, "0" represents the min value,  "1" represents
              the max value
              "value" - the target value of sclk frequency, it should be limited in the
              safe range
      echo "r" > pp_od_clk_voltage
              "r" - reset the sclk frequency, restore the default value instantly
      echo "c" > pp_od_clk_voltage
              "c" - commit the min and max value of sclk frequency to the system
              only after the commit command, the target values set by "s" command
              will take effect.
      Example:
      1)change power profile from "auto" to "manual"
              $ cat power_dpm_force_performance_level
              auto
              $ echo "manual" > power_dpm_force_performance_level
              $ cat power_dpm_force_performance_level
              manual
      2)check the default sclk frequency
              $ cat pp_od_clk_voltage
              OD_SCLK:
              0:        200Mhz
              1:       1400Mhz
              OD_RANGE:
              SCLK:     200MHz       1400MHz
      3)use "s" -- set command to configure the min and max sclk frequency
              $ echo "s 0 600" > pp_od_clk_voltage
              $ echo "s 1 1000" > pp_od_clk_voltage
              $ echo "c" > pp_od_clk_voltage
              $ cat pp_od_clk_voltage
              OD_SCLK:
              0:        600Mhz
              1:       1000Mhz
              OD_RANGE:
              SCLK:     200MHz       1400MHz
      4)use "r" -- reset command to restore the min or max sclk frequency
              $ echo "r" > pp_od_clk_voltage
              $ cat pp_od_clk_voltage
              OD_SCLK:
              0:        200Mhz
              1:       1400Mhz
              OD_RANGE:
              SCLK:     200MHz       1400MHz
