What is P-state management policy used in Windows kernel? RRS feed

  • Question

  • I'm interested in details on the policies offered by the Windows kernel (preferably Seven and S2008) regarding managing P-states, and I'd like to know how these policies are implemented.  In particular, I'm interesting in knowing if processor or platform temperature is ever a factor in choosing a P-state, or is it always assumed that the platform cooling solution is adequate to keep the processor below any self-throttling point.  Also, what is the policy for activating Intel Turbo mode (P0) when available?  Is there a way that I can know all this?  I apologize that this qustion has an Intel slant to it.  (I have the same questions about the Linux kernel, but there I can read the source.)

    Thanks.
