Hi, folks.
I'm writing a cpufreq governor and I want to use some acpi info, like
temperature, to make decisions. Is there a way to get this info inside
the kernel without use sysfs? Where can I find linux-acpi interface
documentation?
Thank you in advance,

There isn't one, as such. You can either evaluate the ACPI methods
yourself or in the case of thermal-related values you can use the
generic thermal code.

How? Is there a how-to or some documentation?
Sorry, but I'm very newbie in ACPI. I've downloaded a few papers, but
I can't find how to evaluate ACPI methods nor how to access generic
thermal code (I only saw static functions on thermal code). I really
dont know where look for..
