There is a thermal device under /sys/devices/platform/asus-nb-wmi. root@t100:~/linux# tree /sys/class/hwmon/ /sys/class/hwmon/ ├── hwmon0 -> ../../devices/platform/coretemp.0/hwmon/hwmon0 └── hwmon1 -> ../../devices/platform/asus-nb-wmi/hwmon/hwmon1 root@t100:/sys/devices/platform/asus-nb-wmi# ls cpufv driver hwmon input modalias power subsystem uevent root@t100:~/linux# sensors coretemp-isa-0000 Adapter: ISA adapter Core 0: +38.0°C (high = +90.0°C, crit = +90.0°C) Core 1: +38.0°C (high = +90.0°C, crit = +90.0°C) Core 2: +39.0°C (high = +90.0°C, crit = +90.0°C) Core 3: +38.0°C (high = +90.0°C, crit = +90.0°C) asus-isa-0000 Adapter: ISA adapter temp1: +6280.0°C I didn't get any information about thermal interface in "Documentation/ABI/testing/sysfs-platform-asus-wmi". Is this a thermal sensor? If it's the fact, how can I change the environment so that this sensor gives me variable data? Thanks, baolu
