Disabling parallel make fixed the issue of not finding the acpi-cpufreq.c file here, but I'm still getting the other issue where it doesn't find the kernel version (unless I disable the line that sets the SKIPKERNEL flag).

I'll try a clean install soon and report back. Thanks for looking upon my issues!

I just made a clean install, now of Fedora 24. After installing, I updated the system and added the dependencies:

Code: Select all

dnf groupinstall "Development Tools" "Development Libraries"
dnf install kernel-headers kernel-devel dkms rpm-build
I still need to comment the line that sets the SKIPKERNEL flag to have a successful compile with dkms.
On Fedora 24 (x86_64) dkms version is 2.2.0.3-34.git.9e0394d.fc24 and make version is 4.1-5.fc24.
Do you remember doing something different with your install? Maybe I'm missing something on my system.

Thanks!

Just checked the installation's history:
I installed rpmbuild, kernel-headers, kernel-devel and kernel-devel-4.2.3-300.fc23.i686 then recognized you used kernel 4.5 so I also installed kernel-4.5.7-200.fc23.i686 and kernel-devel-4.5.7-200.fc23.i686

That's all I did.

Hi,

First off, thank you for all your work!

Has anyone attempted to undervolt an i7 kaby lake? I understand that PHC is not compatible with intel p-states but I am wondering if that is still true...

I found this guide that undervolts newer intel processors, but for windows :(
http://www.ultrabookreview.com/10167-la ... ercloking/
Therefore, undervolting can be done, does anyone know of any way to do this in linux? Please note that they offset the voltage and not directly define it (I am assuming that this is because intel p-states directly controls the scaling of the frequency and voltages).

Sorry if this is a little off-topic, its just that it seems that I might get a response in this thread.

Thanks!

Thanks, sounds interesting! The problem mostly is that Intel made it pretty much impossible to undervolt anything. I don't know how they managed to undervolt a Kaby Lake processor, unfortunately Intel keeps their documentation secret. I'll take a look, but without proper documentation and without an appropriate processor it is virtually impossible to implement the same for Linux...
