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 ?
try to apply this patch 29e9bf1841e4f (x86, mce, therm_throt: Don't report
power limit and package level thermal throttle events in mcelog)

probably not the best solution, but I just ended up disabling the
function in the kernel: (either its below or its under a different name)
X86_MCE_INTEL = n
this way when I watch hulu, dmesg is not spammed with something about
"above threshold" by just watching a movie.
