PHC support for Intel latest CPU families Sandy/Ivy Bridge

[Docet]

Hey everybody,

here I am with bad news from Intel. "There's no easy way to say this, so I'll just say it."* The voltage control interface has been deeply modified, so right now, the latest Intel CPU families are not supported.

Sandy/Ivy Bridge CPUs have 0x00 VIDs @ any FID.

I wrote myself a MSR dumper, to try to relate any other MSR address to FID steps, but it seems there's no good news.
I'm going to try a word-by-word (2 bytes) or byte-by-byte correlation test, but is sounds time consuming.

If anybody has new infos, here's the place to share them!

Regards

Any news on this? I have a Chromebook Pixel based on Ivy Bridge i5, and it runs much hotter than I would like it to. Being able to under-volt it would be a real boon.
