So, the radeon_hd driver has the ability to query thermal GPU status

I am thinking of introducing a
/dev/thermal/<driver_name>/<device_instance>/0 path for thermal info.
I personally think the layout above matches other things in /dev, and
is generic enough that
other drivers can use it.
Example for radeon_hd driver:
/dev/thermal/radeon_hd/0/0 would contain:
"
Radeon HD 5830 - GPU 0
44000
"
First line is a quick driver description of what thermal sensor this
is
Second line is temperature in millidegree Celsius (to avoid floats)
Another Idea in IRC (thanks dr_evil) is returning binary data instead
of
clear text and putting it into a simple struct:
/dev/sensors/radeon_hd/0/0 would be placed over the following API
header:
struct {
char* name;
int32 value;
} sensor_data;
I think sensors may be better as it is more generic and could include
fan speed, etc.
