Subject: RE: [PATCH] drm/amd/powerplay: correct SW smu11 thermal range settings
Ping..
Yes, the lowest settings for thermal controller is 0.
Regards
Evan
Hi Evan,
So due to the below code, we don’t get a chance to set -273.15, right?
+ low = max(SMU_THERMAL_MINIMUM_ALERT_TEMP,
+ range.min / SMU_TEMPERATURE_UNITS_PER_CENTIGRADES);
+ high = min(SMU_THERMAL_MAXIMUM_ALERT_TEMP,
+ range.max / SMU_TEMPERATURE_UNITS_PER_CENTIGRADES);
[CAUTION: External Email]
Comment inline
the temperature min value should be 0, not -273 on smu11.
you can refrence window driver code or register spec.
output_ptr->operating_temperature_min_Limit = 0;
output_ptr->operating_temperature_max_Limit = ppt_info->software_shutdown_temp;
[Quan, Evan] There was a discussion over the min value(0 or -273.15) and we decided to use the later considering the OD case.
All the existing and coming ASICs should follow this design.
and in smu11, the thermal control has a 8bit register to set min and max value, and the unit is temperature.
[Quan, Evan] That is still honored, no violation here.
so there is something wrong with this patch.
Problems with current settings:
1. The min value was overrided to 0 on Vega20 & Navi10. While
the expected should be -273.15 C.
2. The thermal min/max threshold was output in wrong unit on
Navi10 & Arcturus. As TEMP_RANGE_MIN/MAX is already in
millicelsius. And "*1000" in smu_v11_0_start_thermal_control
makes the output wrongly.
