      Obviously, the __memset call is generated by gcc(8.3.1). It optimizes
      this for loop into memset. But this may break on some platforms which
      cannot map device memory correctly. So, just invoke `writel` to handle this.

      drm/amdgpu: fix a GPU hang issue when remove device · 26eb6b51
      Dennis Li authored
      When GFXOFF is enabled and GPU is idle, driver will fail to access some
      registers. Therefore change to disable power gating before all access
      registers with MMIO.
      
      Dmesg log is as following:

      drm/amd/pm: add support to umd P-state function for vangogh · ea173d15
      Xiaojian Du authored
      This patch is to add support to umd P-state function for vangogh.
      It enables the "set" function of 3 sysfs nodes: pp_dpm_mclk,
      pp_dpm_fclk, pp_dpm_socclk, the functions is used to set the DPM
      frequency level of memclk/fclk/socclk.
      Due to only after enabling the "power_dpm_force_performance_level"
      sysfs node, it is allowed to set these three nodes,
      so this patch also enables the "powe_dpm_force_performance_level"
      sysfs node, which is used to change power profile.

      drm/amd/pm: add the fine grain tuning function for renoir · ca55f459
      Xiaojian Du authored
      This patch is to add the fine grain tuning function for renoir.
      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 "standard"
              $ cat power_dpm_force_performance_level
              auto
              $ echo "profile_standard" > power_dpm_force_performance_level
              $ cat power_dpm_force_performance_level
              profile_standard
      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:

      This patch is to improve the fine grain tuning function for RV/RV2/PCO.

      drm/amd/pm: add two new sysfs nodes for vangogh · 9577b0ec
      Xiaojian Du authored
      This patch is to add two new sysfs nodes for vangogh:
      pp_dpm_dclk and pp_dpm_vclk.
      The two sysfs nodes are similar to pp_dpm_fclk/memclk/socclk.
      pp_dpm_dclk represents the DPM frequency of dcn unit.
      pp_dpm_vclk represents the DPM frequency of vcn unit.
