Bob,
Your third patch has an issue.
In rxe_cq_post()
addr = producer_addr(cq->queue, QUEUE_TYPE_TO_CLIENT);
It should be
addr = producer_addr(cq->queue, QUEUE_TYPE_FROM_CLIENT);
After making this change, I have tested my patch and rping works.
Bob can you please point me to the discussion which lead to the current
changes, particularly the need for user barrier.
Zhu can you apply Bob's 3 patches + the change above + my patch and report
back. In my testing it works.
I'll expect Bob to resend

I have not seen a reply to this email thread. Has the issue been
resolved and I missed it?
