In general, the kernel should report temperature readings exactly as
reported by the hardware. The cpu / gpu thermal driver works in 5 degree
increments,but we ought to do more accurate. The temperature will do
linear interpolation between the entries in the table.
Test= $md5sum /dev/zero &
$while true; do grep "" /sys/class/thermal/thermal_zone[1-2]/temp;
sleep .5; done
e.g. We can get the result as follows:
/sys/class/thermal/thermal_zone1/temp:39994
/sys/class/thermal/thermal_zone2/temp:39086
/sys/class/thermal/thermal_zone1/temp:39994
/sys/class/thermal/thermal_zone2/temp:39540
/sys/class/thermal/thermal_zone1/temp:39540
/sys/class/thermal/thermal_zone2/temp:39540
/sys/class/thermal/thermal_zone1/temp:39540
/sys/class/thermal/thermal_zone2/temp:39994

Thermal is TS-ADC Controller module supports
user-defined mode and automatic mode.
User-defined mode refers,TSADC all the control signals entirely by
software writing to register for direct control.
Automaic mode refers to the module automatically poll TSADC output,
and the results were checked.If you find that the temperature High
in a period of time,an interrupt is generated to the processor
down-measures taken;If the temperature over a period of time High,
the resulting TSHUT gave CRU module,let it reset the entire chip,
or via GPIO give PMIC.
