FYI: A Pine64+ 2GB thermal result during a -j4 buildworld's libllvm build on head -r338341

[Mark Millard]

[The build got past doing llvm library related builds and so is doing
less intense buildworld activity.]

During a less intense build stage it shows the likes
of:

# sysctl dev.aw_sid.0.ths-calib dev.aw_thermal
dev.aw_sid.0.ths-calib: 820788078307
dev.aw_thermal.0.gpu2: 24C
dev.aw_thermal.0.gpu1: 24C
dev.aw_thermal.0.cpu: 26C
dev.aw_thermal.0.%parent: simplebus0
dev.aw_thermal.0.%pnpinfo: name=thermal_sensor at 1c25000 compat=allwinner,sun50i-a64-ths
dev.aw_thermal.0.%location: 
dev.aw_thermal.0.%driver: aw_thermal
dev.aw_thermal.0.%desc: Allwinner Thermal Sensor Controller
dev.aw_thermal.%parent: 

It is summer and the room temperature is above
26 degC, more like 28.3 degC.

It does look like the figures are systematically low in
my context.

It will be some time before I'll get a figure for idle.
