Re: [Xen-devel] Infiniband support



Thanks a lot for the response.

I am not sure if I asked it right: I already have Infiniband installed on my kernel and it is working fine in the user space. However, I would like to use the RDMA Verbs API inside the Xen code, like calling RDMA functions to send/receive data. That requires Infiniband headers to be included in the Xen code, but I'm have difficulty with that. So is there any sample code of someone already calling Infiniband/RDMA functions within Xen code or any guide on how to recompile Xen with custom headers?

Thanks a lot!

Xen itself doesn't typically contain I/O drivers at all, that is delegated
to the domain 0 or driver domain kernel(s).

IOW you need to be looking at how to compile Infiniband support into your
dom0 kernel, i.e. in Linux or BSD or whatever, I would presume there are
plenty of resources on that subject on the web.
