Modifying QPI Routing Table Array.

Hi.

Could you tell me how to access the control register for Routing Layer in QPI ??

I want to modify RTA(Router Table Array) for research purpose.

Now I'm using CentOS6, but I couldn't find any piece of codes and "base address" related with QPI.

any hints?

Thanks.

Hello Wonjun,

Intel has not disclosed the QPI router table structure except under an NDA legal agreement, to folks such as BIOS writers working for companies shipping platforms.

Does this clarify things?
