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!

I happened to maintain the phc-intel driver for the last couple of years. You can find the repository with latest updates at since is no more.

That's great, thank you so much! excited to try this out again. I'm very curious how much work this project takes to maintain moving forward, or if it only requires minor changes. Whoever is working on it, please consider a patreon.

Hi, phc-intel is broken for 5.8 because they changed some of the acpi_cpufreq interfacs. I added a 5.8 inc directory and patched it so it compiles it SHOULD work, hopefully, too.

I guess the domain lapsed or something, as it is serving scams now. I got a "send us $250 and get rich quick with Bitcoin" page...

glad there's still some interest in this, thank you for maintaining it this far. I asked on the IRC, linux-phc if there was an official statement on the project, and one user said no. It seems fairly dead. does anyone know more about this, why the forums are down, if they're down for good, etc?
