    Enabling Per Core P-States (PCPS) on Haswell-EP


      Hopefully someone can find the answers I seem to me missing.


      I'm wanting to test a set of applications' performance on Haswell-EP (Xeon E5-1600/2600 v3 series) with a governor that makes use of the "Per Core P-States" feature. I'm having difficultly finding a lot of documentation on the feature to be able to first ensure the test bench I put together will allow me to use the feature as well as how to enable/disable the feature for testing purposes. There are a couple of research publications that mention or use the feature, but they do not give a lot of information on how it was enabled or how to enable/disable it.


      Any help would be appreciated!
