Hello,
If you are looking for information like C States Interrupt Service Requests like Core C1, Package C1e etc., i think these seem to be confidential, they are not advertised publicly.
The only public docs for the Processors are here:
http://www.intel.com/p/en_US/products/server/processor/xeon5000/technical-documents
However, if you have an NDA inplace or respective FAE, you can contact them to see if you can obtain some information from them.
All the best,
Kind Regards,
Aryan.

Thank you for the suggestion.
What I would like to know is the interrupt latency measured from the time of external interrupt
to the time when an application in CPU detects the interrupt (maybe through Interrupt Service Routine).
I've got the following paper from Intel site (under 5500 series page).
http://download.intel.com/design/intarch/papers/321070.pdf http://download.intel.com/design/intarch/papers/321070.pdf
According to the paper, it seems that Fig 8 (page 18) shows an approximate interrupt latency.
But I'm not sure if I can count on these numbers for my purpose.
Any comments would be appreciated!

Hello again,
It is difficult to give you an answer since it is mentioned in the doc that you were referring that it is an estimated value.
May be you can try to post the question on the server room.
