It seems to me it would be useful to have a simple ib_send_page() function.
This is essentially what I'm going to end up writing for what I need IB to do. If there is anyone else that has similar needs or interests I'd be happy to work with them.
The CM works well enough to allow me to initiate connections between HCA's. I'm now going to spend some time trying to write something to kmalloc pages and test the different ways to initiate IB communication between the hosts. Hopefully I can get something smart enough to perform better than IPoIB does.
FYI, this is what SDP in regular sockets mode is doing. The internal buffers are allocated using __get_free_page and then userspace data is copied to/from the buffer which are transmitted/received by posting send/receive on the allocated pages.
OK. Well I would rather make something generic. Besides, wasn't there some MS patent issue? The last thread on the subject that I read kinda made it sound like you were going to look into the issue and respond. Maybe I missed the response; there's a lot of mail in the archives for this list.
In any case, I'd rather just make something more generic that perhaps can be used with NBD.
