P2P 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?

Hello @nathow

Thank you for posting on the Intel® communities.

We understand you have opened an internal case (through phone) with us and we will continue to help you through that channel now. We will therefore close this community case. Thank you.

Uh, what?  That channel referred me to this channel.  I still need assistance.  That channel did not resolve the outstanding concern.

Hhmmm, this is a 13 year-old chipset. It was discontinued 9 years ago and all interactive support for it terminated 7 years ago.

Unfortunately, this question is beyond my ken. Perhaps there's an aged Server BIOS engineer who can help you with this. I suggest that you repost this question in the Servers forum (Intel Community |  Hardware Products |  Server Products). Unfortunately, I can't move this conversation there for you.

Thank you for the suggestion.  I will repost.
