thermal device detected by asus-nb-wmi platform driver
Hi,
I booted Ubuntu13.10 onto ASUS T100 Tablet and upgraded it with upstream kernel (3.14.0-rc7+). There is a thermal device under /sys/devices/platform/asus-nb-wmi.

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,

Adapter: ISA adapter
temp1: +6280.0°CPretty hot ;-). Not your problem, though - it looks like the temperature is reported in Kelvin and the code converting from Kelvin to degrees C turns out to be buggy.

I don't think I understand your question. Yes, this is a thermal sensor. What is it you want to do (in addition to having it report reasonable temperatures) ?
Guenter
Sorry for the confusing question. I'd like to verify whether this sensor works. What I want to do is to make some changes so that the sensor could give me a different temperature value other than always +6280.0°. I have no idea about what kind of changes should I make.
For example, when I work with thermal sensors in CPU core. I can see different temperature values at different core states (idle and busy).
