--- Comment #23 from Rui Zhang 2012-08-02 01:31:01 UTC ---
you can use thermal.psv=80 to override the passive trip point to 80C,
but as the firmware may not generate thermal events for this new trip point,
you need to use thermal.tzp= to set a polling frequency, (Note that this pulls
all the time, no matter the temperature is high or not).
But I think there are some problems to verify,
re: The output of cpupower monitor without the acpi_cpufreq loaded
why the processor is running at 1200 when it is busy? who changes the cpu
frequency?
re: The output of cpupower monitor with the acpi_cpufreq loaded
this seems to be reasonable, and the processor is always near the highest
frequency when it is busy
re: The output of cpupower monitor with the acpi_cpufreq forcefully unloaded
this is also reasonable because the processor is running at 1200 MHZ when the
cpufreq driver is unloaded, and no one changes it any more.
BTW, can you please attach the output of "grep . /sys/class/thermal/*/*"
without acpi_cpufreq loaded?
say "watch -n1 grep . /sys/class/thermal/*/* >> log" and burn the processor.
I'd like to see how thermal works before shutting down.
