i/oat quickdata reference documentation

On an OpenSolaris based OS we use, we have an I/OAT driver which was old and I brought forward from V1 to V3 I/OAT. I have done this based on old documentation and I am having some difficulties (it appears to lose interrupts under high load), and I am looking for some more definitive and up-to-date documentation. The system I am developing on is in fact a Supermicro X10DRS with a pair of these in:

Intel(R) Xeon(R) CPU E5-2620 v3 @ 2.40GHz

The exact same software works 100% reliable on

Intel(R) Xeon(R) CPU E5-2420 v2 @ 2.20GHz

A pointer at recent docs. is all I'm after at the moment

Thanks

- Paul
