The Pine64+ 2GB having been basically idle for hours (and still being basically idle): # sysctl dev.aw_sid.0.ths-calib dev.aw_thermal dev.aw_sid.0.ths-calib: 820788078307 dev.aw_thermal.0.gpu2: 19C dev.aw_thermal.0.gpu1: 19C dev.aw_thermal.0.cpu: 18C dev.aw_thermal.0.%parent: simplebus0 dev.aw_thermal.0.%pnpinfo: name=thermal_sensor@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: So: Well below room temperature and similar to Daniel B.'s results. It does suggest a delta of about 13 degC between idle and the -j4 libllvm example cpu figures --and about 10 degC for the gpus. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)help
