i forgot to mention the other files in the cpu and thermal directory. they
would help setting up the scripts. also you'll need /dev/cpu/microcode,
/dev/cpu/cpuid, /dev/cpu/msr, Intel MCE features, Intel core2/ newer xeon
compiled directly into the kernel and not as modules. they're in the
processor types and features of the kernel. also you'll need the following
from the power management options:
- acpi support
---> everything compiled into the kernel and not as modules with the
exception of dock, asus extras, toshiba extras, acpi container, smart
battery system which are not mandatory.

after controlling this and recompiling if necessary reboot (if you've
recompiled) and do another cat on the thermal trip points to see if it shows
also other states. if it doesn't we will really have to impose the
throttling manually when the temperature goes too high. we'll use the
cpufreq governor to impose the speed when needed and then we'll impose
throttling (processor suspension) when the thermal temp goes too high with
it. if your pc supports limits and other speq steps we could have it lower
the current state to a lower one to cool off a bit. but for this there's the
need to know what your processor can do.
