Hi guys,

I know Linux support the PCID in recent Linux kernels (3.0 and upwards?)
http://linuxeco.com/?p=488

But how about other OSes? *BSD, Windows, MacOS?


Probably Windows supports PCID via update a while ago or maybe since Windows 7. Anyone knows the specifics?

What about the other OSes?

I don't really get it what he meant by "pure architectures" Confused

As for PCID, I have read only the Intel Software Developer Manual so far. Haven't read it on the AMD-side of the equation.
