Support for: Intel(R) Core(TM) i7-1270P

My Lenovo X1 Carbon Gen 10 doesn't seem supported:

I'm happy to help if something needs to be checked

@mpawlowski-eyeo Can you confirm if the latest release of throttled fixes the issue for you?

[mpawlowski-eyeo]

I had to send back the laptop and can't check right now.

I'm not 100% sure if I kept using the https://github.com/erpalma/throttled/commit/2629c786a6f4b17a26dfb6d17b8bf3d69e541937 proof-of-concept commit or ended up pulling from master after https://github.com/erpalma/throttled/pull/310 got merged. I think I pulled from master and it worked.

IMO we can close this ticket and if I find it's not working after I get the laptop again, I'll file a bug.

Alright, so I ended up getting a Lenovo laptop and I can confirm throttled works on Arch Linux:

[I] Detected CPU architecture: Intel AlderLake-P/H
[I] Trying to unlock MSR allow_writes.
[I] Testing if undervolt is supported...
[I] Testing if HWP is supported...
[I] Loading config file.
[I] Starting main loop.

At least on the X1 Yoga (i7-1280P), all cores perform relatively stable at around ~95 C, consuming ~40 W of power after running stress for some time. I was able to see power bursts of up to 66W as well, so I guess throttled is working as expected.
