P2P (Local Peer-to-Peer) on Intel X58 IOH

[nathow]

What minimal combination of registers need to be set/unset in order for P2P to be enabled on this chipset?  How can one test that the same is correctly configured on some given host system?

I do.  I tried with the HPC group, but apparently no-one was able to help--though it really is an HPC question.  Are you familiar with the details behind P2P?

nathow, Thank you very much for sharing that information.

It depends, in order to confirm that we first need to know the information requested previously, depending on the system or platform being used we might be able to assist you with this topic or if it is necessary we will transfer your case to the proper department but we need to know all those details first.

The OS is not Windows.  Your request above seemed to imply a Windows OS.

nathow, Thank you very much for clarifying that information.

In that case, what is the complete model of the motherboard?

If this is a laptop, what is the model of it?

Which specific Linux* version are you using?
