hwmon: (k10temp) Enable AMD3255 Proc to show negative temperature

2023-08-03T08:26:06Z

commit e146503ac68418859fb063a3a0cd9ec93bc52238 upstream. Industrial processor i3255 supports temperatures -40 deg celcius to 105 deg Celcius. The current implementation of k10temp_read_temp rounds off any negative temperatures to '0'. To fix this, the following changes have been made. A flag 'disp_negative' is added to struct k10temp_data to support AMD i3255 processors. Flag 'disp_negative' is set if 3255 processor is found during k10temp_probe. Flag 'disp_negative' is used to determine whether to round off negative temperatures to '0' in k10temp_read_temp.

hwmon: (k10temp) Check range scale when CUR_TEMP register is read-write

2023-04-19T14:06:38Z

Spec says, when CUR_TEMP_TJ_SEL == 3 and CUR_TEMP_RANGE_SEL == 0, it should use RangeUnadjusted is 0, which is (CurTmp*0.125 -49) C. The CUR_TEMP register is read-write when CUR_TEMP_TJ_SEL == 3 (bit 17-16). Add the check to detect it.
