Thank you very much for maintaining the app with new kernel revision.

Only this app can work with intel core and core 2 duo. I still using core 2 duo laptop until today with arch and arch variant distro eg manjaro. Also using Debian variant such as Linux Mint and Debian.

Current intel-undervolt app only can be use with haswell and newer cpu.

I test phc-intel on both sandbridge and lvybridge cpu, but I cant find phc file under /sys/devices/system/cpu/cpu0/cpufreq, what's wrong? Also I follow the tips in archwiki of PHC, I cant find unit dkms-phc-intel.service, and command phc-intel setup not work. why?

UPDATE: after add intel_pstate=disable parameter, phc file appeared. But when I execute command phc-intel start after edit the phc vid config file, it just tell me :: Setting PHC VIDs, but nothing changed. I also try to edit /sys/devices/system/cpu/cpu0/cpufreq/phc_vids manually, but also nothing changed. This file always contains many ZERO even though I actually edit it with vim.

Any help will be great appreciate, thanks!
