Hi All,

I am getting these prints in my Atom based device, running 2.6.35 kernel.

[ 350.084005] CPU0: Temperature above threshold, cpu clock throttled (total
events = 26)
[ 350.084029] CPU1: Temperature above threshold, cpu clock throttled (total
events = 26)
[ 350.085293] CPU0: Temperature/speed normal
[ 350.085311] CPU1: Temperature/speed normal

Seems like these are from therm_throt.c and the flow for this,
Starts from smp_thermal_interrupt(...) method.

Can somebody tell me when this method gets called ?
Also, does this actually throttle the CPU ?

Thanks,
Durga
