Ben A, thank you for you comment. Verified the Trusty configuration as per: git clone git://kernel.ubuntu.com/ubuntu/ubuntu-trusty.git && cd ubuntu-trusty && grep -r CONFIG_X86_POWERNOW_K8= && grep -r CONFIG_X86_ACPI_CPUFREQ= | grep debian debian.master/config/config.common.ubuntu:CONFIG_X86_POWERNOW_K8=y debian.master/config/config.common.ubuntu:CONFIG_X86_ACPI_CPUFREQ=y
As per the Ubuntu maintainer discussion comments (ex. https://bugs.launchpad.net/ubuntu/+source/linux/+bug/355232/comments/15 ) it would seem a strong preference exists not to adjust the defaul config to =m. Would there be a way to achieve undervolt for those who want it in a default install, without modifying the noted configurations or compiling anything (I did notice https://wiki.ubuntu.com/UndervoltingHowto)? ** Changed in: linux (Ubuntu) Importance: Low => Wishlist ** Changed in: linux (Ubuntu) Status: Incomplete => Triaged ** Tags added: bot-stop-nagging trusty ** Description changed: Binary package hint: linux-image-generic - acpi-cpufreq is not a module anymore and is directly included in the kernel. - I think it is a bad decision because it is now very difficult to use phc to undervolt a processor : we need to compile the whole kernel with acpi-cpufreq as a module instead of just compile the module. - http://www.linux-phc.org/index.php + I am using ubuntu jaunty. acpi-cpufreq is not a module anymore and is + directly included in the kernel.
