I get the following from 'acpitool -c':

Make sure your kernel has ACPI processor support enabled.


In fact processor is missing, as ls /proc/acpi only shows:

ac_adapter/ battery/ button/ wakeup


I have enabled everything that I think is required without avail. What am I missing to provide /proc/acpoi/processor ?

/proc/acpi/processor????

This interface had been deprecated for ages and it was finally removed in 2009 and 2010.

The latest version of acpitool is from 2008. This tool is seriously outdated.

Use sys-power/cpupower instead.
