I have done some searching around and each of the OD_RANGE parameters,
as they appear in PP_OD_CLK_VOLTAGE seem to be defined in lines 4495 to
4506 of linux/drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c as
follows:
linux/drivers/gpu/drm/amd/powerplay/hwmgr/smu7_hwmgr.c
As copied from file:
""
case OD_RANGE:
if (hwmgr->od_enabled) {
size = sprintf(buf, "%s:\n", "OD_RANGE");
size += sprintf(buf + size, "SCLK: %7uMHz %10uMHz\n",
data->golden_dpm_table.sclk_table.dpm_levels[0].value/100,
hwmgr->platform_descriptor.overdriveLimit.engineClock/100);
size += sprintf(buf + size, "MCLK: %7uMHz %10uMHz\n",
data->golden_dpm_table.mclk_table.dpm_levels[0].value/100,
hwmgr->platform_descriptor.overdriveLimit.memoryClock/100);
size += sprintf(buf + size, "VDDC: %7umV %11umV\n",
data->odn_dpm_table.min_vddc,
data->odn_dpm_table.max_vddc);
""
Hope this helps
